Spring Veggie Loaded Chicken Potato Casserole: Step-by-Step Instructions

Step 1: Gather and Prep Your Ingredients

Main Ingredients:

• 2 large boneless, skinless chicken breasts (or about 3 cups cooked, shredded chicken)

• 1.5 pounds baby potatoes, quartered (Yukon Gold or red potatoes work best)

• 1 bunch asparagus, trimmed and chopped into 1-inch pieces

• 1 cup green peas, fresh or frozen

• 1 cup carrots, peeled and diced

• 1 cup green beans, trimmed and cut into bite-sized pieces

• 3 cloves garlic, minced

• 1 small yellow onion, finely chopped

• 2 tablespoons olive oil

• 1 tablespoon fresh thyme leaves (or 1 tsp dried thyme)

• Salt and freshly ground black pepper, to taste

For the Creamy Herb Sauce:

• 2 tablespoons butter

• 2 tablespoons all-purpose flour

• 1 1/2 cups chicken broth

• 1 cup whole milk (or half-and-half for a richer version)

• 1/2 cup sour cream or Greek yogurt

• 1 teaspoon Dijon mustard

• 1/4 teaspoon crushed red pepper flakes (optional)

• 1/4 teaspoon ground nutmeg

• 1/4 cup grated Parmesan cheese

• 2 tablespoons fresh parsley, chopped

For Topping:

• 1 1/2 cups shredded mozzarella or cheddar cheese

• Optional: extra Parmesan, crushed crackers or breadcrumbs for texture

Step 2: Cook the Chicken (If Starting with Raw)

If using pre-cooked or leftover chicken, skip to Step 3.

1. Season and Sear: Pat chicken breasts dry and season both sides with salt, pepper, and a sprinkle of thyme. Heat 1 tablespoon olive oil in a skillet over medium-high heat. Add the chicken and sear for 5–6 minutes per side, until golden and cooked through (internal temp 165°F/74°C).

2. Rest and Chop: Remove chicken from skillet, let it rest for 5–10 minutes, then chop or shred into bite-sized pieces. Set aside.

Step 3: Par-Cook the Potatoes

1. Boil: Bring a large pot of salted water to a boil. Add quartered potatoes and cook for 8–10 minutes, just until fork-tender but not falling apart.

2. Drain and Dry: Drain the potatoes well and allow them to steam dry for a few minutes. This will help them roast better later.

Step 4: Roast the Vegetables

1. Preheat Oven: Preheat your oven to 400°F (200°C).

2. Toss Veggies: In a large bowl, toss asparagus, green beans, carrots, peas, and onion with olive oil, minced garlic, thyme, salt, and pepper.

3. Roast: Spread the vegetables in a single layer on a baking sheet and roast for 15–20 minutes, or until slightly browned and tender-crisp. Roasting brings out their sweetness and adds depth to the dish.

Step 5: Make the Creamy Herb Sauce

1. Make a Roux: In a medium saucepan over medium heat, melt butter. Add flour and whisk constantly for 1–2 minutes until a smooth paste forms. This is your roux — the base for your sauce.

2. Add Liquids: Slowly whisk in chicken broth, then milk. Continue whisking until the mixture is smooth.

3. Simmer: Bring to a gentle simmer and cook for 5–7 minutes until thickened.

4. Add Flavor: Stir in sour cream (or Greek yogurt), Dijon mustard, red pepper flakes, nutmeg, Parmesan, and chopped parsley. Taste and adjust seasoning with salt and pepper as needed.

5. Remove from Heat: Set aside. The sauce should be creamy but pourable.

Step 6: Assemble the Casserole

1. Prepare Baking Dish: Lightly grease a 9×13-inch baking dish (or equivalent size).

2. Layer Ingredients:

   • Spread the par-cooked potatoes evenly across the bottom.

   • Scatter the roasted vegetables on top.

   • Add the chopped/shredded chicken evenly over the vegetables.

3. Pour Sauce: Pour the creamy herb sauce over the entire casserole, using a spatula or spoon to ensure everything is coated.

4. Top with Cheese: Sprinkle shredded mozzarella (or cheddar) evenly over the top. For extra crunch, add a sprinkle of breadcrumbs or crushed crackers if desired.

Step 7: Bake the Casserole

1. Bake: Transfer the casserole to the preheated oven and bake uncovered for 25–30 minutes, until bubbly and golden on top.

2. Broil (Optional): For a crispier top, place the casserole under the broiler for 2–3 minutes at the end. Keep a close eye to prevent burning.

Step 8: Rest and Serve

1. Cool Slightly: Let the casserole rest for about 5–10 minutes after removing it from the oven. This helps it set and makes it easier to serve.

2. Garnish: Sprinkle with additional fresh herbs like parsley or thyme before serving for a pop of color and freshness.

3. Serve: Serve hot, either on its own or with a light green salad, crusty bread, or a side of spring fruit.
