Ingredients

Exact quantities were not provided, so the amounts below are practical estimates for a family-size batch of about 4 servings. Adjust to taste.

• 1.5 to 2 lb (680 to 900 g) boneless, skinless chicken thighs or breasts
• 2 bell peppers, sliced (any color)
• 1 small onion, sliced
• 1 can (14.5 oz / 411 g) diced tomatoes
• 3 cloves garlic, minced
• 1 tsp (5 g) salt, plus more to taste
• 1 tsp (2 g) dried oregano or Italian seasoning
• 1/2 tsp (1 g) black pepper
• 1 tbsp (15 ml) olive oil (optional, for sauteing)
• Cooked pasta or rice, for serving

Ingredient Notes

Chicken thighs stay juicier during long cooking, while breasts work well if you prefer leaner meat. Canned diced tomatoes create a flavorful base with little effort. Bell peppers soften as they cook and add a mild sweetness to the sauce.

Equipment You’ll Need

• Slow cooker (4 to 6 quart)
• Cutting board and sharp knife
• Measuring spoons and cups
• Meat thermometer
• Tongs or two forks for shredding

How to Make Slow Cooker Chicken with Peppers and Tomatoes

1. Prep the vegetables. Slice the peppers and onion into strips about 1/4 inch (6 mm) thick. Mince the garlic.
2. Layer the slow cooker. Place the onions and peppers on the bottom of the slow cooker. This keeps them from scorching and helps them cook evenly.
3. Add the chicken. Arrange the chicken on top of the vegetables. Season both sides with salt, pepper, and oregano.
4. Add the tomatoes and garlic. Pour the diced tomatoes with their juices over the chicken and sprinkle the garlic on top.
5. Cook. Cover and cook on low for about 6 to 8 hours, or on high for about 3 to 4 hours. Cooking times vary by slow cooker and chicken size, so start checking near the earlier end of the range.
6. Check for doneness. The chicken is done when it reaches 165 F (74 C) at the thickest part and shreds or slices easily. Use a meat thermometer to confirm.
7. Shred or slice. Transfer the chicken to a cutting board and shred with two forks or slice into pieces. Return it to the sauce and stir gently.
8. Taste and adjust. Add salt or pepper if needed. If the sauce looks thin, leave the lid off for 10 to 15 minutes on high to thicken it slightly.
9. Serve. Spoon the chicken, peppers, and tomatoes over cooked pasta or rice.

Pro Tips for the Best Results

• Layer the vegetables under the chicken so they cook in the flavorful liquid without burning.
• Choose chicken thighs if you want the most tender, forgiving result.
• Pat the chicken dry and season it before adding it to the pot for better flavor.
• Cut the peppers into even strips so they cook at the same rate.
• Avoid lifting the lid often, since each opening lets heat escape and slows cooking.
• Taste the sauce before serving, because canned tomatoes and salt levels vary.

Common Mistakes to Avoid

Dry or stringy chicken: Cooking breasts too long can make them tough. Check the internal temperature early and remove the chicken once it reaches 165 F (74 C).

Watery sauce: Vegetables release liquid as they cook. Reduce the sauce with the lid off for a short time if it looks thin.

Mushy peppers: Peppers can soften too much on high for a long time. Cut them into larger strips or add them later in the cooking time if you prefer more bite.

Variations and Substitutions

• Italian style: Add a pinch of red pepper flakes and a splash of balsamic vinegar.
• Extra vegetables: Add sliced mushrooms along with the peppers.
• Creamy finish: Stir in a little cream cheese or heavy cream during the last few minutes.
• Different cut of meat: Bone-in thighs work well, but cooking times may increase slightly.

Serving Suggestions

This dish is excellent over spaghetti, penne, or rice. Serve it with a simple green salad, crusty bread for soaking up the sauce, or roasted potatoes. Fresh basil or grated Parmesan adds a bright finish.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator within about 2 hours of cooking. Refrigerated leftovers are generally best eaten within 3 to 4 days. Reheat portions on the stove or in the microwave until steaming hot throughout. Freezing is possible, though the peppers may soften more after thawing.

Frequently Asked Questions

Can I use frozen chicken?

It is safest to thaw chicken before slow cooking. Frozen chicken may take longer to reach a safe internal temperature and can affect the texture of the dish.

Can I cook this on high only?

Yes. Cooking on high usually takes about 3 to 4 hours. Check the chicken early to make sure it is cooked through and not drying out.

Do I need to add water?

Usually not. The canned tomatoes and the vegetables release enough liquid to cook the chicken.

What can I serve with this dish?

Pasta and rice are the most common choices, but crusty bread, mashed potatoes, and a simple salad also work well.

How do I know when the chicken is done?

Use a meat thermometer. Chicken is safe to eat when the thickest part reaches 165 F (74 C).
