Detailed Step-by-Step Instructions

Step 1: Prepare the Zucchini Boats

1. Wash and Cut the Zucchini:
   • Begin by thoroughly washing the zucchinis under cold water to remove any dirt or residues. After washing, cut the zucchinis in half lengthwise. If you prefer, you can slice them slightly at an angle for a more visually appealing presentation.
2. Scoop Out the Centers:
   • Using a spoon or melon baller, gently scoop out the center of each zucchini half to create a hollow “boat.” Leave about a ¼-inch border around the edges to ensure the zucchini boats retain their shape during grilling. The scooped-out zucchini flesh can be saved for another recipe, such as adding to a stir-fry or smoothie.
3. Brush the Zucchini with Olive Oil:
   • Drizzle the hollowed-out zucchini halves with olive oil. Use a pastry brush or your hands to ensure that the zucchini boats are evenly coated. This will help them grill nicely and prevent them from drying out. Season with salt and pepper to taste. You can also rub a minced garlic clove into the surface for an extra layer of flavor, but this step is optional.
4. Preheat the Grill:
   • While you’re preparing the zucchini, preheat your grill to medium-high heat (about 375°F – 400°F or 190°C – 200°C). If using a grill pan, heat it on the stovetop over medium-high heat. You can also prepare these zucchini boats in the oven if a grill is not available, but grilling them adds a beautiful smoky flavor.

Step 2: Prepare the Caprese Filling

1. Prepare the Tomatoes:
   • While the zucchini boats are being prepped, wash and quarter the cherry or grape tomatoes. The tomatoes should be ripe, firm, and bursting with flavor, as they are the centerpiece of the Caprese stuffing.
2. Prepare the Fresh Mozzarella:
   • Shred the fresh mozzarella cheese or cut it into small cubes. Fresh mozzarella is soft and creamy, which gives a perfect contrast to the slightly crisp grilled zucchini. If you prefer a more intense cheese flavor, you can substitute fresh mozzarella with burrata or provolone.
3. Chop the Fresh Basil:
   • Finely chop the fresh basil leaves. Fresh basil is essential in bringing that bright, herbaceous flavor to the dish. Don’t skip this step—basil is a defining ingredient in the classic Caprese flavor profile.
4. Assemble the Filling:
   • In a medium-sized bowl, combine the quartered tomatoes, shredded mozzarella, chopped basil, and a tablespoon of extra virgin olive oil. Drizzle with balsamic vinegar, if using, for a tangy finish that complements the sweetness of the tomatoes. Season the mixture with salt and pepper to taste. You can also add a teaspoon of dried oregano and a pinch of red pepper flakes for an additional layer of flavor if desired. Stir gently to combine.

Step 3: Grill the Zucchini Boats

1. Grill the Zucchini:
   • Once your grill has reached the desired temperature, place the zucchini boats cut-side down on the grill. Close the lid and grill for 5-6 minutes. You want the zucchini to develop grill marks and start to soften but still hold its shape. If you’re using a grill pan on the stovetop, place the zucchini halves cut-side down and grill for the same amount of time.
2. Flip the Zucchini:
   • After 5-6 minutes, carefully flip the zucchini boats over so that the hollowed-out side is facing up. At this point, the zucchini should be slightly tender but not fully cooked. You’ll now fill them with the Caprese mixture and continue grilling.

Step 4: Stuff the Zucchini Boats

1. Stuff with the Caprese Filling:
   • Spoon the prepared Caprese filling generously into each zucchini boat. Be sure to pack the filling in lightly so that each boat is full but not overflowing.
2. Grill the Stuffed Zucchini:
   • Close the grill lid and grill the stuffed zucchini boats for an additional 6-8 minutes. The zucchini will finish cooking and become tender, while the mozzarella will melt beautifully, blending with the tomatoes and basil to create a delicious filling. If you like, you can sprinkle the stuffed boats with grated Parmesan cheese for a cheesy crust, or add extra mozzarella if you’re craving a cheesier version.

Step 5: Garnish and Serve

1. Add Fresh Basil:
   • After grilling, remove the zucchini boats from the grill and let them cool slightly. Garnish with additional fresh basil leaves for a pop of color and flavor.
2. Serve and Enjoy:
   • Serve the grilled Caprese-stuffed zucchini boats warm. They can be enjoyed as a main dish or as a side, depending on the portion size. They also pair beautifully with a light salad or grilled proteins like chicken or fish.

Tips and Variations

1. Choosing the Right Zucchini:
   • Select medium-sized zucchinis that are firm and free of soft spots. Larger zucchinis may be watery and not as flavorful, while smaller ones may be too delicate to stuff and grill. Opt for zucchinis that are about 6-8 inches long for the best balance of flavor and texture.
2. Add Protein to the Filling:
   • For a heartier version, add cooked ground turkey, chicken, or even sausage to the Caprese filling. You can also add cooked quinoa or rice for a vegetarian protein boost.
3. Grill Marks and Flavor:
   • For the best grilled flavor, make sure your grill grates are clean and lightly oiled. This will ensure that the zucchini doesn’t stick to the grates and that it develops perfect grill marks. The smoky flavor from the grill is an essential part of this dish!
4. Using the Oven Instead:
   • If you don’t have access to a grill, these zucchini boats can easily be prepared in the oven. Preheat your oven to 375°F (190°C), place the stuffed zucchini boats on a baking sheet, and bake for 20-25 minutes or until the zucchini is tender and the cheese is melted and bubbly.
5. Use Pesto:
   • Instead of using olive oil and balsamic vinegar, you can drizzle the zucchini boats with fresh pesto for a unique twist on the classic Caprese. Pesto adds an extra layer of richness and complements the basil in the filling.
6. Low-Carb and Keto-Friendly:
   • This recipe is naturally low-carb and keto-friendly. For an even more decadent option, sprinkle the stuffed zucchini boats with a generous amount of shredded mozzarella and Parmesan cheese before grilling.

Health Benefits and Nutritional Information

• Low in Calories and Carbs: Zucchini is a low-calorie vegetable that is naturally low in carbohydrates. This dish is an excellent choice for those following a low-carb or keto diet.
• Rich in Antioxidants: Tomatoes are a rich source of antioxidants like lycopene, which has been shown to support heart health and reduce inflammation. Basil is also packed with antioxidants and has anti-inflammatory properties.
• Good Source of Healthy Fats: The olive oil used in this recipe provides healthy monounsaturated fats, which are great for heart health.
• Calcium and Protein: Fresh mozzarella and Parmesan cheese offer a good amount of calcium and protein, both essential for bone health and muscle repair.

• As a Main Dish: Serve the zucchini boats with a side of leafy greens or a light pasta for a complete meal. They also pair well with grilled meats like chicken, shrimp, or steak.
• As a Side Dish: These zucchini boats are perfect as a side for a summer barbecue, paired with grilled fish, burgers, or roasted vegetables.

Frequently Asked Questions

• Can I make these zucchini boats ahead of time? Yes, you can prepare the zucchini boats ahead of time, stuff them with the filling, and store them in the refrigerator for up to 24 hours. Just grill them when you’re ready to serve.
• Can I freeze stuffed zucchini boats? Yes, you can freeze the stuffed zucchini boats before grilling. Wrap them tightly in plastic wrap and place them in a freezer bag. When ready to cook, bake them straight from the freezer, adding a few extra minutes to the grilling time.

The Appeal of Grilled Zucchini Boats

What makes zucchini boats so appealing is their versatility. They are naturally a great vessel for a variety of fillings, making them a fantastic option for adapting to different seasons and preferences. During the summer, when zucchini is abundant and at its peak, these boats are a great way to highlight fresh, seasonal ingredients. They are also a great way to use up leftover vegetables or to incorporate other garden-fresh produce into your meals.

Grilled zucchini boats, like the Caprese variety, are light yet filling, and they’re perfect for meal prepping. You can prepare them ahead of time, grill them when ready, or even freeze them for future enjoyment. The dish is also ideal for entertaining, as it’s simple to prepare in large batches and can be easily served as an appetizer or side dish at barbecues or gatherings.

Zucchini: A Nutritional Powerhouse

Zucchini is not only delicious but also a nutritional powerhouse. It’s low in calories but high in vitamins, minerals, and fiber. A medium zucchini provides a good amount of vitamin C, which is essential for immune function and skin health. It’s also a good source of potassium, which is vital for heart health and muscle function. Additionally, zucchini is high in water content, making it a hydrating vegetable that can help support digestion and maintain skin health.

Zucchini’s versatility and mild flavor make it an excellent base for various dishes, and by grilling it, you’re unlocking a smoky flavor that pairs beautifully with the fresh, creamy filling in the Caprese-stuffed boats.

Why Grilling?

Grilling adds a unique depth of flavor to zucchini that is hard to achieve through other cooking methods. The process of grilling caramelizes the natural sugars in the zucchini, enhancing its flavor while giving it a slightly crispy texture on the outside. Grilled zucchini also retains its nutrients better than other forms of cooking, as the high heat of grilling helps to preserve vitamins such as vitamin C and antioxidants.

Grilling also creates those beautiful char marks, which not only contribute to the aesthetic of the dish but also introduce an additional layer of smoky, savory flavor that pairs perfectly with the fresh and tangy Caprese filling.

Creative Variations to Experiment With

While the Caprese-style filling is undoubtedly a classic, you can get creative with different stuffing options. Here are a few variations to try:

1. Mexican-Inspired Zucchini Boats: Replace the mozzarella and basil with a mixture of shredded cheddar or Monterey Jack cheese, diced tomatoes, black beans, corn, and taco-seasoned ground turkey or beef. Top with a dollop of sour cream and a sprinkle of cilantro for a fun twist on the classic recipe.
2. Mediterranean Zucchini Boats: Swap the mozzarella with crumbled feta cheese and add olives, diced cucumbers, and sun-dried tomatoes. A drizzle of tzatziki sauce and a sprinkle of oregano will give these boats a Mediterranean flair.
3. Cheesy Spinach and Artichoke Zucchini Boats: Combine sautéed spinach, artichoke hearts, and cream cheese for a rich and indulgent filling. Add a handful of Parmesan cheese and mozzarella for a cheesy, creamy filling that’s sure to please.
4. Bacon and Avocado Zucchini Boats: Add crispy bacon bits and avocado to the Caprese filling for a savory, crunchy twist. The smoky flavor from the bacon pairs wonderfully with the creamy avocado, creating a filling that’s rich in flavor and texture.
5. Vegan Caprese Zucchini Boats: For a vegan version, replace the mozzarella with cashew cheese or a dairy-free cheese alternative. You can also use a balsamic glaze to finish the dish instead of regular balsamic vinegar. Add more fresh herbs such as oregano or thyme to bring out additional flavors.

Making Grilled Zucchini Boats Your Own

One of the reasons grilled zucchini boats are so popular is their adaptability. You can easily switch up the stuffing to match your dietary preferences, the season, or what’s available in your kitchen. Not only does this make the dish exciting and customizable, but it also ensures that you can enjoy it year-round. As you explore new flavors and ingredients, you may discover your own perfect variation.

A Crowd-Pleaser for Every Occasion

Grilled Caprese-Stuffed Zucchini Boats are perfect for a variety of occasions. Their light and fresh flavors make them ideal for summer barbecues, picnics, or as a starter to a larger meal. They also work beautifully as a main course for a light lunch or dinner, especially when paired with a side salad or some fresh crusty bread.

For a more formal gathering, these zucchini boats can be served as an appetizer, with each boat individually portioned for guests to enjoy. The vibrant colors of the red tomatoes, green basil, and golden zucchini make for an appealing and festive dish that’s sure to impress.

Pairing the Zucchini Boats with Drinks

When serving Grilled Caprese-Stuffed Zucchini Boats, consider pairing them with a light, refreshing beverage. White wines such as Sauvignon Blanc, Pinot Grigio, or Chardonnay work well with the fresh and tangy flavors of the Caprese stuffing. If you prefer non-alcoholic options, consider serving sparkling water with a squeeze of lemon or a light iced tea with fresh herbs like mint or basil.

Perfect for Meal Prep and Leftovers

If you’re making these zucchini boats in advance, you’ll be glad to know that they store well for later meals. You can prepare them and store them in the refrigerator for up to 2-3 days. The flavors only get better as they meld together over time. Reheat in the oven or microwave when you’re ready to enjoy, or eat them cold as part of a fresh salad.

If you want to freeze the stuffed zucchini boats, place them in a freezer-safe container or wrap them tightly in foil. When you’re ready to enjoy them, simply bake from frozen, adding a few extra minutes to the grilling or baking time.

Notes

Grill Temperature: To achieve the best grill marks and texture, preheat your grill to medium-high heat (375°F - 400°F or 190°C - 200°C). If using a grill pan, make sure it's properly heated before placing the zucchini on it.

Zucchini Size: For best results, use medium-sized zucchinis. Larger zucchinis may become too watery and may not hold the filling well, while smaller ones might be too delicate. Ideally, each zucchini should be about 6-8 inches long.

Avoid Overstuffing: While it’s tempting to pile on the Caprese filling, be sure not to overstuff the zucchini boats. A slightly heaping filling is fine, but overstuffing may cause it to spill out during grilling.

Cheese Substitutes: If fresh mozzarella isn’t available, you can substitute it with other cheeses like goat cheese, ricotta, or even a sharp cheddar for a different flavor. However, mozzarella works best for its melting properties.

Balsamic Glaze: If you prefer a tangy, slightly sweet finish, consider drizzling your zucchini boats with balsamic glaze after grilling, instead of balsamic vinegar in the filling. The glaze adds a richer flavor and a shiny finish.

Chill the Zucchini: If you're making these ahead, you can prepare the zucchini boats and fill them with the Caprese mixture, then refrigerate them for up to 24 hours before grilling. This will allow the flavors to meld together.

Vegetarian-Friendly: This recipe is naturally vegetarian and can be made vegan by replacing mozzarella with plant-based cheese alternatives and skipping the Parmesan topping.

Adding Protein: For a heartier meal, consider adding cooked ground turkey, chicken, or sausage to the Caprese filling. Alternatively, grilled shrimp or sliced steak could be served alongside as a topping.
