Step-by-Step Instructions

1. Preheat and Prepare

Preheat your oven to 375°F (190°C) . Lightly grease a 9×13-inch baking dish with cooking spray or a little olive oil.

2. Arrange the Chicken and Peppers

Place the chicken pieces in the prepared baking dish, skin side up. Scatter the sliced bell peppers over and around the chicken.

3. Make the Sauce

In a medium bowl, stir together the marinara sauce and the dry Italian dressing mix until well combined.

4. Cover and Bake

Pour the sauce evenly over the chicken and peppers, making sure everything is well coated. Cover the dish tightly with foil. Bake for 45 minutes.

5. Uncover and Finish

Remove the foil and bake for an additional 15-20 minutes, or until the chicken is cooked through and tender, and the sauce is bubbly and slightly thickened.

6. Rest and Serve

Let the casserole rest for a few minutes before serving. The sauce will thicken slightly as it cools. Serve with a big wooden spoon, letting everyone scoop out the tender chicken, peppers, and rustic red sauce.


Pro Tips for Perfect Chicken Cacciatore

  • Use Bone-In Chicken: Bone-in, skin-on chicken thighs and drumsticks are the best choice for this dish. The bone and skin add flavor and moisture, and the meat becomes wonderfully tender as it braises.
  • Don’t Skimp on the Sauce: Choose a good-quality marinara sauce, or even a crushed tomato sauce with a little added Italian seasoning. The sauce is what makes this dish so special.
  • Add a Little Pizazz: While the 4-ingredient version is perfect, you can add a few fresh herbs, a splash of red wine, or a sprinkle of red pepper flakes for extra flavor.
  • Let It Rest: Letting the casserole rest for a few minutes allows the sauce to settle and the flavors to meld beautifully.

Serving Suggestions

  • Over Hot Buttered Egg Noodles: The classic pairing. The wide, flat noodles are perfect for soaking up all that rich, savory sauce.
  • With Spaghetti or Linguine: A more traditional Italian-style serving.
  • Alongside Fluffy White Rice: Another wonderful way to enjoy every drop of the sauce.
  • With a Simple Green Salad: A crisp, fresh salad with a tangy vinaigrette balances the richness of the casserole.
  • With Crusty Bread or Garlic Toast: Perfect for swiping through the bottom of the pan and catching every last bit of sauce.

Leftovers: A Second Delicious Meal

This casserole is wonderful the next day. Shred the leftover chicken and stir it into the remaining sauce. Serve it over pasta or rice for a quick and comforting lunch.

This Oven-Baked 4-Ingredient Chicken Cacciatore Casserole is more than just a recipe; it’s an invitation to slow down and enjoy the simple pleasures of home cooking. It’s a dish that asks for very little but gives back so much—comfort, warmth, and the joy of sharing a meal with those we love.
