Chicken Cacciatore Casserole Recipe: Rustic Bake With Herbed Tomato Sauce

This baked chicken cacciatore transforms a classic stovetop dish into a hands-off casserole with all the bold flavors intact. The secret is layering tender chicken with a rich tomato sauce infused with garlic, herbs, and bell peppers.

What makes this version special is the oven finish, which deepens the flavors and creates a bubbling, golden top without constant stirring. The chicken stays juicy while the vegetables soften into the sauce.

The result is a rustic one-dish meal that tastes like it simmered for hours but comes together with minimal effort. Serve it with crusty bread to soak up every last drop of the herbed tomato sauce.

Perfect for weeknight dinners or feeding a crowd. Here’s how to make it.

Ingredients for Chicken Cacciatore Casserole

Bold flavors come from simple ingredients layered with care in this rustic dish.

The chicken is the foundation—boneless, skinless thighs stay juicier than breasts during baking. Look for them at Whole Foods or your local butcher for the best quality. Bell peppers add sweetness and color; any color works, but red peppers (with their higher sugar content) caramelize beautifully. San Marzano canned tomatoes are worth the splurge for their rich, sweet flavor.

No white wine? Chicken broth with a splash of lemon juice mimics the acidity. Fresh herbs can replace dried—use triple the amount since dried are more concentrated. For extra depth, add a pinch of fennel seeds or a bay leaf to the sauce. If using fresh tomatoes, roast and peel them first to remove excess moisture.

This casserole reheats well—store leftovers in an airtight container for up to 4 days in the fridge or freeze for 3 months. The flavors actually improve overnight as everything melds together. Always bring to room temperature before reheating to prevent drying out.

Step-by-Step Instructions for Chicken Cacciatore Casserole

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear and Brown the Chicken Thighs

Heat the 2 tbsp olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Pat the 1.5 lb chicken thighs dry with paper towels and season both sides evenly with the 1 tsp kosher salt and 0.5 tsp ground black pepper.

Working in batches if needed, add the chicken thighs skin-side down and sear undisturbed for 4-5 minutes until the skin becomes deep golden brown and crispy. Flip and sear the other side for another 3-4 minutes until evenly browned. Transfer to a plate and set aside.

Step 2: Sauté the Vegetables and Build the Base

In the same skillet, add the 2 whole bell peppers (sliced into strips) and the 1 whole yellow onion (thinly sliced). Cook over medium heat for 5-6 minutes, stirring occasionally, until the vegetables soften and begin to caramelize.

Add the 4 cloves garlic cloves (minced) and cook for 30 seconds until fragrant. Stir in the 2 tbsp tomato paste, 1 tsp dried oregano, 1 tsp dried basil, and 0.5 tsp red pepper flakes, cooking for 1 minute to deepen the flavors.

Step 3: Deglaze and Simmer the Sauce

Pour in the 0.5 cup dry white wine and scrape up any browned bits from the bottom of the skillet with a wooden spoon. Let the wine simmer for 2-3 minutes until it reduces by half.

Add the 28 oz canned diced tomatoes (with juices) and the 0.5 cup chicken broth. Stir to combine, then return the chicken thighs to the skillet, nestling them into the sauce. Bring to a gentle simmer.

Step 4: Bake to Perfection

Preheat your oven to 375°F. Cover the skillet with a lid or foil and transfer it to the oven. Bake for 25-30 minutes until the chicken is cooked through and the sauce has thickened slightly.

Remove from the oven and let it rest for 5 minutes before serving. The chicken should be tender and the sauce rich and flavorful, with the vegetables fully softened and infused with the herbs.

Step 5: Garnish and Serve

Sprinkle the 0.25 cup fresh parsley (chopped) over the top just before serving. This adds a bright, fresh contrast to the rich, rustic flavors of the dish.

Serve hot, directly from the skillet, with crusty bread or over polenta to soak up the delicious herbed tomato sauce. Each bite should deliver tender chicken, sweet peppers, and a perfectly balanced sauce.

Storing and Reheating Leftovers

Refrigerator Storage

Let the casserole cool completely before transferring to airtight containers. It will keep in the fridge at 40°F or below for up to 4 days. I use glass containers because they don’t absorb odors like plastic sometimes can. 💡

Freezer Storage

This dish freezes beautifully for up to 3 months. Portion into freezer-safe bags or containers, leaving 1 inch of headspace for expansion. Squeeze out excess air to prevent freezer burn. Label with the date so you remember.

Stovetop Reheating

Transfer to a saucepan and heat over medium-low heat for 10-15 minutes, stirring occasionally. Add a splash of chicken broth or water if the sauce seems thick. This method keeps everything perfectly tender.

Oven Reheating

Preheat oven to 350°F and cover the casserole with foil. Bake for 20-25 minutes until bubbling. This works great for larger portions and revives the dish’s fresh-baked feel. 🔥

Microwave Reheating

For single servings, microwave on 70% power for 2-3 minutes, stir, then continue in 30-second intervals until reaching 165°F. Cover with a damp paper towel to retain moisture.

Pro Tip

I always let the dish sit at room temperature for 15-20 minutes before reheating. This prevents the chicken from drying out. The flavors taste even richer the next day.
