There’s something deeply satisfying about a meal that practically cooks itself while filling your home with incredible aroma. This slow cooker creation combines tender chicken with rich tomato flavors for a hands-off dish that never sacrifices taste.

The beauty lies in its simplicity—just a few pantry staples and a slow cooker transform everyday ingredients into something extraordinary. Low, steady heat allows the flavors to meld perfectly, resulting in juicy chicken and a sauce that’s rich and deeply savory.

By the time dinner rolls around, you’ll have a restaurant-quality meal ready to serve with minimal effort. The chicken becomes fall-apart tender, while the tomatoes break down into a thick, flavorful base that coats every bite.

Serve it over rice, pasta, or with crusty bread to soak up every last drop. This is comfort food at its most convenient.

Ingredients for Chicken and Tomato Crockpot

Pantry staples plus chicken and tomatoes. Hands-off cooking at its finest.

The chicken is everything here. Thighs stay juicier than breasts in the slow cooker—look for skinless, boneless to save prep time. Costco has great bulk packs, or grab them from the butcher counter at Whole Foods if you want to support local. The tomatoes? San Marzano canned are the gold standard, but any good brand works (just avoid the ones with added salt or herbs).

No tomato paste? Double the ketchup in a pinch, though it’ll be sweeter. Swap dried herbs for fresh at one-third the amount—just add them at the end so they don’t turn bitter. Using chicken breasts instead of thighs? Don’t overcook (4 hours max on low). The broth can be swapped for water plus bouillon, but Better Than Bouillon chicken base is my go-to for depth.

Leftovers keep 4-5 days in the fridge, and the flavors actually improve overnight. Freeze portions for up to 3 months—just thaw in the fridge before reheating. The parsley garnish is best fresh, so add it right before serving (or skip it if you’re lazy).

Step-by-Step Instructions for Chicken and Tomato Crockpot

Here’s the effortless method that delivers deep, complex flavors with minimal hands-on time.

Step 1: Sear the Chicken for Depth

Heat the 2 tbsp Olive Oil in a large skillet over medium-high heat. While it heats, pat the 1.5 lb Boneless Skinless Chicken Thighs dry with paper towels—this prevents steaming and ensures a proper sear.

Season both sides with the 1 tsp Kosher Salt and 0.5 tsp Freshly Ground Black Pepper. Sear the chicken for 3-4 minutes per side until deeply golden brown. You’re not cooking it through, just building a flavor foundation. The seared bits left in the pan will dissolve into the sauce later.

Step 2: Build the Flavor Base

Transfer the seared chicken to your slow cooker. In the same skillet, add the finely diced 1 whole Yellow Onion and cook for 3-4 minutes until softened and translucent. Add the minced 4 cloves Garlic Cloves and cook for 30 seconds until fragrant—don’t let it burn.

Stir in the 2 tbsp Tomato Paste and 1 tsp Paprika, cooking for 1 minute to deepen the flavors. This step is crucial—it removes the raw edge from the tomato paste and paprika. Deglaze the pan with the 0.5 cup Chicken Broth, scraping up all those browned bits, then pour this mixture over the chicken in the slow cooker.

Step 3: Add Tomatoes and Herbs

Pour the 2 cans Canned Diced Tomatoes (with their juices) over the chicken. These tomatoes form the base of your sauce, so their quality matters. Add the 1 tbsp Dried Oregano and 1 tbsp Dried Basil, crushing them between your fingers as you sprinkle to release their essential oils.

Drizzle the 1 tbsp Red Wine Vinegar over the top—this balances the natural sweetness of the tomatoes and brightens all the flavors. Stir everything together gently, just enough to distribute the ingredients without breaking up the chicken thighs.

Step 4: Slow Cook to Perfection

Cover the slow cooker and set it to low heat. Cook for 6-7 hours until the chicken is fall-apart tender. You’ll know it’s done when the 1.5 lb Boneless Skinless Chicken Thighs shred easily with a fork and the sauce has thickened slightly. If you’re short on time, cook on high heat for 3-4 hours, but the low-and-slow method yields the most tender results.

About 30 minutes before serving, taste and adjust seasoning if needed. The flavors will have melded beautifully, with the tomatoes breaking down into a rich, velvety sauce that clings to the chicken.

Step 5: Finish and Serve

Just before serving, sprinkle the chopped 0.25 cup Fresh Parsley over the top. This adds a pop of fresh color and a bright, herby note to balance the rich, savory sauce. Stir gently to incorporate some of the parsley into the dish while reserving some for garnish.

Serve hot, with the sauce spooned generously over the chicken. The 1.5 lb Boneless Skinless Chicken Thighs will have absorbed all the Mediterranean flavors from the tomatoes, herbs, and spices, creating a dish that tastes like it simmered all day—because it did.

Storing and Reheating Leftovers

Refrigerator Storage

Let the dish cool for no more than 2 hours before transferring to airtight containers. I use glass containers with snap-on lids for easy reheating. Store in the fridge at 40°F or below for up to 4-5 days. The flavors actually deepen overnight. ❄️

Freezer Storage

This freezes beautifully for up to 3 months without losing quality. Use quart-sized freezer bags laid flat to save space. Leave 1 inch of headspace for expansion and squeeze out excess air to prevent freezer burn.

Stovetop Reheating

My preferred method: transfer to a saucepan, add ¼ cup chicken broth or water, and heat over medium-low for 10-12 minutes. Stir occasionally to prevent sticking. The sauce will thicken as it warms.

Microwave Reheating

For quick meals, microwave individual portions covered with a damp paper towel. Use 70% power for 2-3 minutes, stir, then continue in 30-second bursts until reaching 165°F. Add a splash of broth if dry. 🔥

Thawing Tips

Always thaw frozen portions in the fridge overnight—never at room temperature. For faster thawing, place the sealed bag in a bowl of cold water, changing the water every 30 minutes. Never refreeze after thawing.
