Chicken Marinara Crock Pot Recipe: Tomato-Braised Chicken With Italian Herbs

This slow-cooker method transforms simple ingredients into tender, fall-off-the-bone chicken bathed in rich marinara sauce with Italian herbs.

I developed this recipe to deliver restaurant-quality results with minimal effort. The crock pot does all the work, slowly braising the chicken in tomato sauce until perfectly tender.

What emerges is juicy chicken pieces coated in a thick, herb-infused marinara that soaks into every bite. The aroma alone will have everyone gathering in the kitchen.

Serve over pasta, polenta, or crusty bread to soak up every drop of the flavorful sauce.

Ingredients for Chicken Marinara Crock Pot

Simple ingredients transform into restaurant-quality chicken with Italian flair in your slow cooker.

The chicken thighs are non-negotiable here—bone-in works too but takes slightly longer. Costco and Sam’s Club sell family packs perfect for this. For the marinara, Rao’s or Victoria brands have the right consistency and flavor depth. If using fresh herbs, triple the amount since dried are more concentrated. Look for marinara with visible herb flecks for the best results.

No marinara on hand? Crushed tomatoes plus Italian seasoning gets you 80% there. Swap chicken thighs for breasts (reduce cook time to 3-4 hours). Fresh out of balsamic? Red wine vinegar works but use 1 tbsp less. The tomato paste can be omitted in a pinch, but the sauce won’t be as rich. Trader Joe’s has great pre-minced garlic if you’re short on time.

Leftovers taste even better the next day as flavors meld. Store in airtight containers for up to 4 days in the fridge or freeze for 3 months. The sauce thickens as it cools—thin with broth or water when reheating if needed.

Step-by-Step Instructions for Tomato-Braised Chicken With Italian Herbs

This method ensures tender chicken infused with rich tomato and herb flavors.

Step 1: Sear the Chicken Thighs

Heat the 2 tablespoons olive oil in a large skillet over medium-high heat until shimmering. Pat the 2 lb boneless, skinless chicken thighs dry with paper towels—this step is crucial for achieving a proper sear.

Season both sides of the chicken with the 1 teaspoon kosher salt and ½ teaspoon freshly ground black pepper. Working in batches if necessary, sear the thighs for 3-4 minutes per side until deep golden brown and they release easily from the pan. Transfer to your slow cooker, leaving the browned bits in the skillet for the next step.

Step 2: Build the Flavor Base

In the same skillet, add the finely diced 1 whole yellow onion and cook over medium heat for 5 minutes until softened and translucent. Add the 5 cloves minced garlic cloves and cook for 30 seconds until fragrant—be careful not to let it burn.

Stir in the 2 tablespoons tomato paste and cook for 1 minute, which deepens its flavor and removes the raw taste. Deglaze the pan with the 2 tablespoons balsamic vinegar, scraping up all the browned bits from the bottom. This step captures all that concentrated flavor for your sauce.

Step 3: Combine and Slow Cook

Transfer the onion mixture to the slow cooker with the chicken. Add the 3 cups marinara sauce, ½ cup chicken broth, 1 tablespoon dried basil, 1 tablespoon dried oregano, 1 teaspoon dried thyme, and ½ teaspoon red pepper flakes.

Stir to combine all ingredients, ensuring the chicken is well-coated with the sauce. Cover and cook on low for 6-7 hours or on high for 3-4 hours. The chicken is done when it shreds easily with a fork and the sauce has thickened slightly.

Step 4: Finish and Serve

Once the cooking time is complete, give everything a good stir. The chicken should be fall-apart tender and the sauce rich and aromatic. Taste and adjust seasoning if needed, though the combination of marinara, herbs, and balsamic vinegar should provide a balanced flavor.

Ladle into shallow bowls and garnish with the ¼ cup chopped fresh parsley. The parsley adds a bright, fresh contrast to the deep, savory flavors of the dish. Serve with crusty bread or over pasta to soak up every bit of the delicious sauce.

Make-Ahead Tips for This chicken marinara crock pot

Night Before Prep

You can prep all your vegetables and measure spices the night before. Store diced onion and minced garlic in separate airtight containers in the fridge. Combine all dried herbs in a small bowl and cover tightly. This saves 15-20 minutes on cooking day. 💡

Morning Assembly

Sear the chicken in the morning, then transfer everything to your crock pot. The beauty of this dish is that it cooks unattended. I start mine at 7 AM on low setting, and it’s ready by 2 PM with perfectly tender results every time.

Crock Pot Timing

For the most tender chicken, stick to low for 6-7 hours. If you need it faster, switch to high for 3-4 hours. I recommend setting a timer for 1 hour before it’s done to prepare your pasta or bread.

Portion Control

Divide the finished dish into meal-sized portions before storing. I use 16-ounce glass containers that hold exactly one serving. This makes reheating individual portions easier and prevents waste.

Freezer Meals

This recipe freezes beautifully for up to 3 months. Let cool completely, then transfer to freezer-safe bags, removing as much air as possible. Label with the date and reheat from frozen in the microwave with 1-2 tablespoons water. ❄️

Reheating Tips

For best results, reheat on the stovetop over medium-low heat with a splash of chicken broth. Microwave works in a pinch—use 50% power and stir every 2 minutes until heated through.
