Why This Recipe Works

Set-it-and-forget-it: Ten minutes of morning prep translates to a fragrant, fully cooked dinner the minute you walk through the door.
Built-in flavor layering: Smoked sausage renders its seasoning into the tomatoes, which in turn baste the chicken for six hours—no sauté pan required.
Budget-friendly stretch: Bone-in thighs stay juicy and cost a fraction of breast meat, while canned tomatoes and dried herbs keep the grocery total under ten dollars in most regions.
One-pot nutrition: Protein, veg, and a silky sauce mean you can serve it straight from the crock or over rice/pasta without extra pans.
Freezer hero: Leftovers freeze flat in zip bags for up to three months; thaw overnight and reheat on the stove for an instant comfort meal.
Customizable heat: Use mild Italian sausage for kids or kick it up with hot andouille; either way the slow cooker mellows and balances the spice.
Weekend to weekday: Double the batch on Sunday, tuck half into the freezer, and you’ve got a head start on next week’s busy night.

Ingredients You'll Need

Great slow-cooker dinners start with grocery-store discernment. Look for plump chicken thighs that still have their skin on; the skin acts like a built-in baster, melting slowly and self-basting the meat. If you can only find skinless, that’s fine—just tuck two tablespoons of butter on top before you set the lid. For sausage, I prefer smoked Andouille for its assertive garlic and cayenne notes, but a simple smoked kielbasa works if you’re feeding spice-shy kids. Seek out a brand without corn syrup so the sauce stays silky, not sticky.

Fire-roasted diced tomatoes are my non-negotiable; the charred edges add a campfire depth you can’t get from plain diced tomatoes. In a pinch, regular diced tomatoes plus a quick pass under your broiler (spread on a sheet pan for five minutes) will approximate the flavor. Tomato paste in a tube keeps forever in the fridge and gives the sauce enough body to cling to rice or crusty bread. Buy dried oregano and basil in small jars; they lose punch after about six months, and since the slow cooker cooks low, you want herbs that still sing.

Bell peppers bring sweetness; I use a mix of red and yellow for color. Slice them thick so they survive the six-hour swim and still offer a little bite. Onion choice matters less—yellow, white, or even a leftover half of a sweet onion work. Garlic should be fresh; the powdered stuff turns harsh over long cooking. If you’re out of fresh garlic, substitute half a teaspoon of garlic powder per clove but add it only in the last hour. Chicken stock sounds extra, yet a quarter cup loosens the sauce just enough to prevent scorching on the slow cooker’s hot edge.

Finally, the secret handshake: a single bay leaf and a pinch of smoked paprika. Both whisper “someone’s been tending a pot of jambalaya all day” without steering the dish into Cajun territory. Finish with chopped parsley for brightness, or swap in sliced scallions if you like an oniony snap.

How to Make Easy Slow Cooker Chicken and Sausage with Tomatoes Dinner

Layer the aromatics first

Scatter sliced onions and bell peppers across the bottom of a 6-quart slow cooker. These vegetables act as a built-in rack, elevating the chicken so it doesn’t stew in its own juices and turn rubbery. Season lightly with salt and pepper; they’ll season everything else as the pot heats.

Whisk the tomato base

In a medium bowl, whisk together the two cans of fire-roasted tomatoes, tomato paste, chicken stock, dried oregano, dried basil, smoked paprika, and a generous crank of black pepper. The paste wants to stay in clumps, so whisk like you mean it for thirty seconds; your future self will thank you for the velvety sauce.

Season the chicken

Pat chicken thighs dry with paper towels—moisture is the enemy of browning, even in a slow cooker. Sprinkle both sides with kosher salt, cracked pepper, and a whisper of garlic powder if you like extra depth. Leave the skin on; it renders and flavors the sauce.

Nestle and pour

Place the chicken, skin-side up, on top of the vegetables. Add the sliced sausage around and between the pieces; it’s okay if some pieces sink—they’ll bob later. Pour the tomato mixture evenly over everything. Add the bay leaf, tucking it under the liquid so it doesn’t float away and become a chewy surprise.

Low and slow is the goal

Cover and cook on LOW for 6 hours or on HIGH for 3½ hours. Resist peeking; every lift of the lid adds 15 minutes to your cook time. The chicken is done when an instant-read thermometer inserted near but not touching the bone registers 175 °F—slightly higher than the USDA minimum because thighs forgive overcooking and become silkier.

Finish with freshness

Taste the sauce and adjust salt. Fish out the bay leaf; it has done its duty. Stir in chopped parsley for color and a hit of chlorophyll brightness. If the sauce seems thin, ladle some into a small bowl, whisk in a teaspoon of cornstarch, and return to the pot for ten minutes on HIGH to thicken.

Serve strategically

Spoon over steamed rice, cheese grits, or wide egg noodles. Alternatively, serve straight from the crock with thick slices of crusty bread for sopping. Garnish with extra parsley or sliced scallions for crunch and color.

Expert Tips

Overnight Flavor Boost

Assemble everything the night before, cover, and refrigerate the insert. In the morning, set it straight into the base and hit START—no extra prep, deeper melded flavors.

De-Fat the Sauce

Chill leftovers; the fat will solidify on top. Lift it off with a spoon for a lighter sauce and happier arteries.

Crisp the Skin

If you can’t resist crispy skin, transfer the chicken to a sheet pan and broil 3 min at the end. Watch closely; it browns fast.

Double Duty Veg

Add a handful of baby spinach during the last 10 minutes for color and a nutrient bump; it wilts instantly.

Keep-Warm Window

Running late? Most slow cookers auto-switch to WARM after the timer ends. The chicken holds beautifully for up to 2 hours without drying.

Food-Safe Thicken

Never add raw flour or cornstarch directly to the hot crock—it clumps. Always slurry first in a small bowl with cool liquid.

Variations to Try

Cajun Kick: Swap the smoked sausage for andouille, add ½ tsp cayenne, and stir in thawed frozen okra during the last 30 minutes for a gumbo vibe.
Mediterranean Twist: Replace paprika with 1 tsp dried oregano and ½ tsp fennel seeds; add a handful of pitted Kalamata olives and a sprinkle of feta at the end.
Creamy Comfort: Stir in 4 oz cream cheese cubes and ¼ cup heavy cream during the last 15 minutes for a tomato-cream sauce reminiscent of Tuscan chicken.
White Bean Stew: Add two drained cans of cannellini beans during the last hour to stretch the meal and boost fiber.
Vegetarian Version: Skip chicken and sausage; substitute two cans of chickpeas and 2 cups cubed butternut squash. Use vegetable stock and add 1 tsp smoked paprika for depth.

Storage Tips

Cool leftovers completely within two hours for food safety. Transfer to airtight containers and refrigerate up to four days. The flavors actually improve on day two when the paprika and herbs have a chance to mingle. For longer storage, portion into quart-size freezer bags, press out excess air, and freeze flat on a sheet pan. Once solid, stack like books; they’ll keep three months. Thaw overnight in the fridge or submerge the sealed bag in cold water for an hour, then reheat gently on the stove over medium-low, adding a splash of chicken stock to loosen.

Planning a potluck? Transport the insert straight from the fridge to the slow-cooker base at the host’s house, set to WARM, and stir occasionally. If you need to freeze individual lunches, ladle the saucy chicken into silicone muffin molds; freeze, pop out, and store the pucks in a bag. One or two pucks plus a handful of frozen rice make a speedy desk-lunch microwave bowl.

Frequently Asked Questions

You can, but reduce the cook time to 4 hours on LOW. Breasts dry out faster than thighs; swap in 1 cup additional stock and check for doneness with a thermometer at 160 °F, then remove immediately.

Vegetables release liquid as they cook. Remove chicken and sausage, set the slow cooker to HIGH, and leave the lid ajar for 30 minutes to reduce. Or whisk 1 tbsp cornstarch with 2 tbsp cold water, stir in, and cook 10 minutes more.

Yes. Use the Slow-Cook function on LOW for the same 6 hours, or pressure-cook on HIGH for 12 minutes with natural release for 10 minutes. Reduce stock to 2 tbsp to avoid thin sauce.

As written, yes. If thickening, use cornstarch or arrowroot rather than flour, and always check sausage labels—some brands contain wheat fillers.

Only if your slow cooker is 8-quart or larger. Overfilling prevents proper heat circulation. Layer ingredients the same way and add 1 extra hour on LOW to ensure the center reaches safe temperature.
