Meaty Zucchini Casserole with Ground Beef: Step-by-Step Instructions
Step 1: Gather Your Ingredients
Before beginning, assemble all the ingredients to streamline the cooking process.
Ingredients:
-
1.5 to 2 pounds ground beef (choose lean or medium fat depending on preference)
-
3 to 4 medium zucchinis (about 2 pounds), washed and sliced into ¼-inch thick rounds or half-moons
-
1 medium onion, finely chopped
-
3 cloves garlic, minced
-
1 can (14.5 oz) diced tomatoes, drained (optional for added moisture and flavor)
-
1 cup shredded mozzarella or cheddar cheese (plus extra for topping)
-
½ cup grated Parmesan cheese
-
1 cup tomato sauce or marinara sauce
-
1 tablespoon olive oil
-
1 teaspoon dried oregano
-
1 teaspoon dried basil
-
½ teaspoon crushed red pepper flakes (optional)
-
Salt and freshly ground black pepper to taste
-
Fresh parsley or basil for garnish (optional)
Step 2: Prepare the Zucchini
-
Wash the zucchinis thoroughly and trim off the ends.
-
Slice into rounds about ¼ inch thick or cut lengthwise into half-moons, depending on your preferred texture.
-
To remove excess moisture from the zucchini (which can make the casserole watery), lightly salt the slices and place them in a colander for 15 to 20 minutes.
-
After resting, pat the zucchini dry with paper towels to remove released water.
Step 3: Cook the Ground Beef Mixture
-
Heat olive oil in a large skillet over medium heat.
-
Add the chopped onion and sauté for 3 to 4 minutes until softened and translucent.
-
Add the minced garlic and cook for another 30 seconds until fragrant.
-
Increase heat to medium-high and add the ground beef. Break the meat apart with a spatula or wooden spoon.
-
Cook until browned and no longer pink, about 7 to 10 minutes.
-
Drain excess fat if necessary.
-
Stir in diced tomatoes (if using), tomato sauce, dried oregano, basil, crushed red pepper flakes (if desired), salt, and pepper.
-
Simmer the mixture for 10 minutes to blend flavors and thicken the sauce slightly. Stir occasionally to prevent sticking.
Step 4: Preheat the Oven and Prepare the Baking Dish
-
Preheat your oven to 375°F (190°C).
-
Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of olive oil to prevent sticking.
Step 5: Layer the Casserole
-
Spread a thin layer of the cooked beef and tomato sauce mixture evenly on the bottom of the baking dish.
-
Arrange a layer of zucchini slices evenly over the beef.
-
Sprinkle a light layer of mozzarella or cheddar cheese over the zucchini.
-
Repeat the layering: beef mixture, zucchini, cheese until all ingredients are used, ending with a cheese layer on top.
-
Sprinkle the grated Parmesan cheese over the top layer for a flavorful crust.
Step 6: Bake the Casserole
-
Cover the baking dish with aluminum foil to retain moisture.
-
Bake in the preheated oven for 30 minutes.
-
Remove the foil and bake for an additional 10 to 15 minutes, or until the cheese is bubbly and golden brown on top.
-
If desired, switch to broil for the last 2 minutes to get a nicely browned crust—watch carefully to avoid burning.
Step 7: Rest and Serve
-
Remove the casserole from the oven and let it rest for 10 minutes before serving. This helps the layers set and makes slicing easier.
-
Garnish with fresh parsley or basil if desired.
-
Serve warm as a satisfying main dish alongside a fresh salad or crusty bread.
