Ingredient Notes & Details

• Boneless Skinless Chicken Breasts
  Chicken breasts provide a lean, protein-rich base for this casserole. You can also substitute boneless chicken thighs if you prefer darker meat with extra richness and moisture. Fresh chicken works best, but thawed frozen chicken can also be used.
• Jarred Pasta Sauce
  Choose a high-quality marinara or tomato-based pasta sauce. Many sauces already contain garlic, onions, herbs, and seasonings, which help create authentic cacciatore flavor with minimal effort. Look for varieties labeled rustic tomato, roasted garlic, or Italian herb.
• Sliced Bell Peppers
  Bell peppers are a classic ingredient in traditional chicken cacciatore. Use a mixture of red, yellow, and green peppers for beautiful color and slightly different flavor profiles. Fresh peppers provide the best texture.
• Sliced Mushrooms
  Mushrooms add earthy flavor and create the signature cacciatore taste. White button mushrooms, cremini mushrooms, or baby bella mushrooms all work wonderfully in this recipe.

Step-by-Step Instructions

1. Step 1: Preheat the Oven
   Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and make cleanup easier later.
2. Step 2: Prepare the Chicken
   Place the chicken breasts in a single layer in the prepared baking dish. If your chicken breasts are especially thick, consider pounding them slightly for more even cooking.
3. Step 3: Add the Vegetables
   Scatter the sliced bell peppers and mushrooms evenly over the chicken. Try to distribute them across the entire dish so every serving gets plenty of vegetables.
4. Step 4: Pour on the Sauce
   Cover everything with the pasta sauce. Use a spoon to spread the sauce evenly over the vegetables and chicken, ensuring all ingredients are coated. This layer of sauce helps keep the chicken moist while baking.
5. Step 5: Bake Until Tender
   Cover the dish tightly with aluminum foil. Bake for approximately 35 to 45 minutes. Cooking time may vary depending on the thickness of your chicken breasts.
6. Step 6: Check for Doneness
   The chicken should reach an internal temperature of 165°F (74°C). When fully cooked, the chicken will be tender and easy to cut with a fork. The vegetables should be softened, and the sauce should be bubbling around the edges.
7. Step 7: Rest and Serve
   Allow the casserole to rest for 5 minutes before serving. This helps the juices redistribute and makes serving easier. Spoon extra sauce and vegetables over each piece of chicken for maximum flavor.
