  • 3 bell peppers (red, yellow, green), sliced – Adds color, natural sweetness, and a healthy dose of vitamins A and C.
  • 1 medium onion, thinly sliced – Builds a sweet, savory flavor base as it caramelizes during slow cooking.
  • 3 garlic cloves, minced – Infuses the dish with deep, aromatic flavor.
  • 1 (14.5 oz) can diced tomatoes (with juices) – Provides a rich, slightly acidic base that enhances the chicken and vegetables.
  • 1/2 cup low-sodium chicken broth – Adds moisture and depth without overpowering the dish.
  • 1 tablespoon tomato paste – Concentrates the tomato flavor and thickens the sauce.
  • 1 teaspoon dried oregano – Lends a warm, herbaceous note that complements the peppers.
  • 1/2 teaspoon smoked paprika – Adds subtle smokiness and depth.
  • Salt and freshly ground black pepper, to taste – Essential for seasoning and bringing out all the natural flavors.

Optional Add-ins:

  • 1/2 teaspoon red pepper flakes – For a spicy kick.
  • 1 teaspoon Italian seasoning – To enhance the herb profile further.
  • 1 tablespoon balsamic vinegar – Adds a touch of acidity and sweetness to balance the flavors.

Step-by-Step Instructions

Prepare Your Crockpot

Step 1: Prepare Your Crockpot

Spray the inside of your slow cooker with a light coating of non-stick spray or use a liner for easy cleanup.

Step 2: Layer the Vegetables

Place the sliced onions and bell peppers at the bottom of the crockpot. This forms a flavorful base that allows the vegetables to soak up juices and tenderize slowly.

Step 3: Add the Chicken

Lay the chicken breasts over the vegetables. Season with salt, pepper, oregano, and smoked paprika.

Step 4: Add Sauce Ingredients

In a bowl, combine the diced tomatoes (with juices), tomato paste, chicken broth, garlic, and any optional ingredients like balsamic vinegar or red pepper flakes. Stir well, then pour over the chicken and vegetables.

Step 5: Cook Low and Slow

Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the chicken is cooked through and tender. Internal temperature should reach 165°F (74°C).

Step 6: Shred and Stir

Once cooked, shred the chicken directly in the crockpot using two forks and stir it back into the sauce. Let it sit for 5-10 minutes to soak up the flavors.


Why This Recipe Works

This recipe is beloved because the slow-cooked method locks in moisture and enhances the natural sweetness of the bell peppers. The acidity from the tomatoes balances the richness of the chicken, while the blend of herbs and spices brings warmth and complexity.


Pro Tips for Perfect Results

  • Use chicken thighs if you prefer more flavor and a richer texture.
  • Don’t overfill the crockpot—leave about 1-2 inches from the top to allow for even cooking.
  • Add fresh basil or parsley just before serving for a pop of freshness.
  • Make it creamy: Stir in a splash of cream or coconut milk before serving for a richer sauce.

Serving Suggestions

  • Serve over white or brown rice for a hearty, satisfying meal.
  • Pair with buttered noodles or quinoa for added texture and protein.
  • Use leftovers to stuff into pita bread or tortillas for flavorful wraps.
  • Serve with a crisp green salad or garlic bread for a complete dinner spread.

Frequently Asked Questions: Chicken and Bell Pepper Crockpot Recipe

1. Can I use frozen chicken in the crockpot?

It’s not recommended to use frozen chicken directly in a crockpot due to food safety concerns. Slow cookers heat food gradually, which means frozen chicken may spend too much time in the danger zone temperature range (40°F–140°F), allowing bacteria to grow. Always thaw chicken fully in the refrigerator before adding it to your crockpot.

2. Can I substitute the bell peppers with other vegetables?

Absolutely. While bell peppers add color and sweetness, you can substitute or add vegetables like zucchini, mushrooms, carrots, or spinach. Just keep in mind that softer vegetables should be added in the last hour of cooking to prevent overcooking.

3. How do I store and reheat leftovers?

Let the dish cool completely, then store in an airtight container in the refrigerator for up to 4 days. To reheat, warm in a saucepan over medium heat or microwave in short bursts, stirring in between. This dish also freezes well for up to 3 months—just thaw overnight in the fridge before reheating.

4. Can I make this recipe spicier?

Yes, for extra heat, add red pepper flakes, diced jalapeños, or a dash of hot sauce when combining the sauce ingredients. You can also stir in cayenne pepper or chipotle powder to intensify the spice level to your liking.
