Ingredients
- 2 tablespoons olive oil (30 ml)
- 1 1/2 pounds boneless, skinless chicken thighs or breasts (680 g), cut into bite-sized pieces
- 1 medium onion, chopped
- 3 cloves garlic, minced
- 2 cups carrots, sliced (about 3 large carrots) (300 g)
- 2 cups broccoli florets (150 g)
- 1 cup frozen peas (150 g), thawed
- 1 can (14.5 oz / 411 g) diced tomatoes, drained
- 1/2 cup low-sodium chicken broth (120 ml)
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- Salt and black pepper to taste
- 1 cup shredded cheddar cheese (about 115 g)
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Prepare the Chicken and Vegetables Preheat your oven to 375ยฐF (190ยฐC). Heat olive oil in a large skillet over medium heat. Add the chicken pieces and cook until browned and no longer pink inside, about 5-7 minutes. Remove from heat and set aside.
- Sautรฉ Aromatics and Mix Casserole Ingredients In the same skillet, add chopped onion and garlic and sautรฉ until softened, about 3 minutes. In a large mixing bowl, combine browned chicken, sautรฉed onions and garlic, carrots, broccoli florets, peas, drained diced tomatoes, chicken broth, thyme, rosemary, salt, and pepper. Mix well.
- Assemble and Bake the Casserole Transfer the mixture into a greased 9×13-inch (23×33 cm) baking dish and spread evenly. Sprinkle shredded cheddar cheese evenly on top. Cover with foil and bake for 30 minutes.
- Finish Baking and Serve Remove the foil and bake uncovered for an additional 10 minutes, or until the cheese is melted, bubbly, and lightly browned. Insert a meat thermometer into the thickest part of the casserole; chicken should reach 165ยฐF (74ยฐC) for safe consumption. Let the casserole rest for 5 minutes before serving. Garnish with chopped fresh parsley if desired.
Helpful Tips
- Ensure chicken pieces are evenly sized for uniform cooking.
- You can substitute vegetables based on seasonal availability, such as green beans or zucchini.
- Leftovers can be reheated thoroughly in the microwave or oven until piping hot (165ยฐF/74ยฐC internal temperature).
- For a richer sauce, add 1/2 cup (120 ml) of cream or sour cream before baking if desired.
Storage and Make-Ahead
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat leftovers until the internal temperature reaches 165ยฐF (74ยฐC) for food safety.
Do not freeze the casserole after baking as cheese texture may change upon thawing.
