Serve over rice or with crusty bread to soak up every last bit of the rich sauce. This becomes a family favorite with its balanced flavors and easy preparation.
Ingredients for Chicken and Peppers Crock Pot
Simple ingredients transform into restaurant-quality comfort food with minimal effort in your crock pot.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Skinless Chicken Breasts 🍗 | 1 ½ lb | Cut into 1-inch pieces |
| Red Bell Peppers 🌶️ | 2 whole | Sliced into strips |
| Green Bell Peppers 🌶️ | 2 whole | Sliced into strips |
| Yellow Onion 🧅 | 1 whole | Diced medium |
| Garlic Cloves 🧄 | 4 cloves | Minced fine |
| Canned Diced Tomatoes 🍅 | 1 can | 14.5 oz, undrained |
| Chicken Broth 💧 | ½ cup | Low-sodium preferred |
| Tomato Paste 🍅 | 2 tbsp | For depth of flavor |
| Dried Oregano 🌿 | 1 tsp | Mediterranean variety |
| Dried Basil 🌿 | 1 tsp | Or substitute fresh |
| Paprika 🌶️ | 1 tsp | Sweet or smoked |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
The chicken is the foundation—boneless, skinless breasts stay moist during the long cook. Look for vibrant, firm bell peppers (mix colors for visual appeal) at your regular supermarket. For the tomatoes, San Marzano canned are ideal, but any quality brand works. The broth deepens flavor; low-sodium lets you control salt levels precisely.
No red bell pepper? Extra green peppers work fine. Out of fresh garlic? Garlic powder at one-third the amount (about 1 tsp) substitutes well. Need more liquid? Add an extra 1/4 cup broth. For heat, a pinch of cayenne or red pepper flakes complements without overpowering. The tomato paste can be swapped for 2 tbsp ketchup in a pinch.
This keeps beautifully in the fridge for 4-5 days—the flavors actually improve overnight. Freezes for up to 3 months (portion before freezing for easy reheating). The peppers soften perfectly after storing, so it’s ideal for meal prep.

Step-by-Step Instructions for Chicken and Peppers Crock Pot
This hands-off method delivers tender chicken and vibrant peppers with minimal effort.
Step 1: Sear the Chicken for Depth of Flavor
Heat the 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the 1.5 lb boneless skinless chicken breasts cut into 1-inch pieces and sear until lightly browned, about 3-4 minutes per side.
This browning step creates a fond that enhances the dish’s richness. Don’t crowd the pan—cook in batches if needed. The chicken doesn’t need to be fully cooked at this stage; it will finish in the slow cooker.
Step 2: Layer Vegetables and Aromatics
Place the 2 whole red bell peppers sliced into strips and 2 whole green bell peppers sliced into strips in the bottom of your crock pot. Add the 1 whole yellow onion diced medium and 4 cloves garlic cloves minced fine.
These form the flavor base. The peppers will soften beautifully during cooking, while the onion and garlic melt into the sauce, creating a sweet, aromatic foundation for the dish.
Step 3: Combine Remaining Ingredients and Slow Cook
Add the seared chicken to the crock pot. Pour in the 1 can canned diced tomatoes (with juices), 0.5 cup chicken broth, and 2 tbsp tomato paste. Sprinkle with 1 tsp dried oregano, 1 tsp dried basil, 1 tsp paprika, 1 tsp salt, and 0.5 tsp black pepper.
Stir gently to distribute the spices evenly. Cover and cook on low for 6-7 hours or high for 3-4 hours, until the chicken is fork-tender and the peppers are silky. Stir once halfway through if possible.
Step 4: Adjust Seasoning and Serve
Before serving, taste and adjust seasoning if needed. The flavors will have melded into a rich, tomato-based sauce with tender chicken and soft peppers.
Let it rest for 10 minutes off the heat to allow the juices to settle. Serve hot over rice, pasta, or with crusty bread to soak up the flavorful sauce.
Pro Tips For Making Chicken And Peppers Crock Pot
- Sear Chicken First: I learned this the hard way—tossing raw chicken straight into the crock pot gives you bland meat. A quick 2-minute sear in a hot pan locks in flavor and adds a depth the slow cooker alone can’t.
- Slice Peppers Thin: Sounds obvious, but thick strips stay crunchy and undercooked. Cut them into 1/4-inch slices so they soften properly in 4-6 hours on low.
- Skip Overcrowding: My first few batches turned out watery because I crammed in too many peppers. Stick to 2 bell peppers max for 1.5 lbs of chicken to avoid a soggy mess.
- Use Fresh Garlic: After burning three batches with powdered garlic, I finally switched to minced fresh cloves. 3-4 cloves give a bright, clean flavor that jarred or dried just can’t match.
Serving Suggestions for This Recipe
Over Rice or Pasta
Serve this hearty dish over steamed white rice or linguine pasta to catch every bit of the rich, tomato-based sauce. I recommend 1 cup uncooked rice for 4 servings—it soaks up the flavors beautifully. 💛
With Crusty Bread
A loaf of warm Italian or sourdough bread is perfect for dipping into the sauce. Look for a baguette or ciabatta from your local bakery. Toast slices lightly for extra crunch.
Fresh Garnishes
Brighten up your plate with fresh toppings like chopped parsley or grated Parmesan cheese. A sprinkle of red pepper flakes adds a nice kick for those who enjoy heat.
Side Salad Pairing
A simple green salad with a light vinaigrette balances the richness of the dish. Toss 4 cups mixed greens with 2 tbsp olive oil and 1 tbsp balsamic vinegar for a refreshing contrast.
Roasted Vegetables
Add roasted zucchini or broccoli as a side for extra texture and nutrition. Toss with 1 tbsp olive oil and roast at 400°F for 15-20 minutes. 🔥
For Meal Prep
Portion leftovers into airtight containers with rice or pasta for easy lunches. The flavors deepen overnight, making it even more delicious the next day. Reheat in the microwave for 2-3 minutes.

Frequently Asked Questions
Can I use chicken thighs instead of breasts?
Boneless, skinless thighs work beautifully and stay extra juicy. They have more fat, which adds richness. Adjust cooking time to 5-6 hours on low since they cook faster than breasts.
Do I need to sear the chicken first?
Searing adds depth but isn’t mandatory. Skip it for a true “dump and go” method. If you do sear, use medium-high heat for just 3-4 minutes per side to avoid drying out the meat.
How can I make this spicier?
Add 1/2 tsp cayenne pepper or 1 chopped jalapeño with the other ingredients. For heat lovers, stir in 1/4 tsp red pepper flakes at the end. The flavors develop beautifully during cooking.
Can I cook this on high instead of low?
Yes, cook on high for 3-4 hours instead of 6-7 on low. Check at 3 hours—the chicken should be fork-tender. High heat works well when you’re short on time.
