Ingredients

3-4 boneless, skinless chicken breasts (about 2 lbs)
1/4 tsp salt
1/4 tsp pepper
1/4 tsp garlic powder
1 medium zucchini
1 medium yellow squash
1/2 medium sweet yellow onion
1/2 cup prepared pesto
4 oz parmesan cheese
4 oz mozzarella cheese

Instructions

Step 1: Preheat the oven to 375˚F.
Step 2: Chop the zucchini, yellow squash, and onion, then combine them in a bowl.
Step 3: In a large casserole dish, lay the chicken breasts in a flat, single layer. Season evenly with salt, pepper, and garlic powder.
Step 4: Spread the chopped vegetables evenly over the chicken. Dollop the pesto over the veggies, then top with parmesan and mozzarella cheeses.
Step 5: Bake on the middle rack for 35-45 minutes, or until the chicken reaches an internal temperature of 165˚F. If the topping begins to brown too much, loosely cover the dish with foil and continue baking until done.
Step 6: Serve hot and enjoy your comforting casserole!

Tips & Variations

For a creamier texture, stir a little cream or ricotta cheese into the pesto before spreading.
Try adding sliced cherry tomatoes or bell peppers for extra color and flavor.
Use fresh herbs like basil or thyme to garnish before serving.
Swap out mozzarella for a sharper cheese like fontina or gouda if preferred.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. This casserole can also be frozen for up to 2 months; thaw overnight in the fridge before reheating.
