Ingredients

  

• 2 to 2.5 pounds boneless, skinless chicken thighs (or breasts), trimmed
• 1 medium yellow onion, thinly sliced
• 4 garlic cloves, minced
• 1 red bell pepper, sliced into strips
• 1 (14.5-ounce) can diced tomatoes, undrained
• 1/3 cup pitted Kalamata olives, halved
• 1/3 cup green olives (Castelvetrano or similar), halved
• 2 tablespoons capers, drained (optional but recommended)
• 2 tablespoons tomato paste
• 1/3 cup low-sodium chicken broth (or dry white wine)
• 2 tablespoons extra-virgin olive oil
• 1 teaspoon lemon zest and 2 tablespoons fresh lemon juice
• 1 1/2 teaspoons dried oregano
• 1 teaspoon dried basil or Italian seasoning
• 1/2 teaspoon smoked paprika (or regular paprika)
• 1/2 teaspoon red pepper flakes (optional, for heat)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 2 tablespoons chopped fresh parsley or basil, for garnish
• Cooked couscous, orzo, rice, or crusty bread, for serving

Instructions

 

• Prep the base: Add the sliced onion and bell pepper to the bottom of your slow cooker. Sprinkle with a pinch of salt.
• Mix the sauce: In a bowl, whisk together diced tomatoes, tomato paste, chicken broth, olive oil, lemon zest, lemon juice, garlic, oregano, basil, paprika, red pepper flakes, salt, and black pepper until smooth and combined.
• Layer the chicken: Place the chicken thighs over the vegetables. Pour the sauce mixture over the top, making sure the chicken is mostly covered.
• Add olives and capers: Scatter the Kalamata olives, green olives, and capers over everything.
• Cook low and slow: Cover and cook on Low for 5 to 6 hours, or on High for 2.5 to 3.5 hours, until the chicken is very tender and easily pulls apart.
• Adjust seasoning: Taste the sauce and add more salt, pepper, or lemon juice if needed. If you want a thicker sauce, remove the lid for the last 20 to 30 minutes or stir in a slurry made from 1 teaspoon cornstarch and 1 tablespoon water, then cook 10 more minutes.
• Finish and serve: Shred or slice the chicken into large chunks. Stir back into the sauce. Garnish with fresh parsley or basil. Serve over couscous, orzo, rice, or alongside crusty bread to soak up the juices.

Storage Instructions

• Refrigerator: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Freeze in meal-size portions for up to 3 months.

  Thaw overnight in the fridge before reheating.

• Reheating: Warm gently on the stovetop over medium-low heat or in the microwave, adding a splash of broth or water if the sauce thickens too much.

Why This is Good for You

• Lean protein: Chicken thighs offer iron, B vitamins, and satisfying protein that keeps you full.
• Healthy fats: Olives and extra-virgin olive oil provide monounsaturated fats linked to heart health.
• Antioxidants: Tomatoes, garlic, and peppers bring vitamin C and plant compounds that support immunity.
• Balanced meal: Pairing with whole grains like brown rice or whole-wheat couscous adds fiber for steady energy.

Pitfalls to Watch Out For

• Overcooking chicken breasts: If using breasts instead of thighs, reduce the cook time on Low to about 4 to 4.5 hours to prevent dryness.
• Too salty: Olives and capers add salt. Use low-sodium broth and taste before adding extra salt at the end.
• Watery sauce: Some slow cookers create more liquid. Thicken by simmering uncovered at the end or adding a small cornstarch slurry.
• Skipping the acid: Lemon juice brightens the dish.

  Don’t skip it, especially if using sweeter tomatoes.

• Overcrowding with add-ins: Extra vegetables are great, but too many can dilute the sauce. Keep the ratio balanced.

Variations You Can Try

• Artichoke twist: Add 1 cup quartered artichoke hearts (drained) in the last hour of cooking.
• Sun-dried tomato boost: Stir in 1/3 cup chopped sun-dried tomatoes (oil-packed, drained) for deeper flavor.
• Herb-forward: Swap dried oregano and basil for 1/4 cup chopped fresh herbs at the end for a brighter finish.
• Spicy version: Increase red pepper flakes to 1 teaspoon and add a pinch of cayenne.
• Veggie-loaded: Add sliced zucchini or mushrooms in the last 1.5 to 2 hours so they don’t get mushy.
• Creamy finish: Stir in 2 to 3 tablespoons heavy cream or coconut milk at the end for a silky sauce.
• Chicken swap: Use bone-in, skinless thighs for extra flavor. Remove bones before serving.

FAQ

Can I make this on the stovetop instead of in a slow cooker?

Yes.

Sauté the onion and pepper in olive oil, add the garlic, then the tomatoes, broth, and seasonings. Nestle in the chicken and olives. Simmer covered on low for about 25 to 35 minutes, until the chicken is tender.

Adjust seasoning and finish with lemon and herbs.

Do I need to brown the chicken first?

You don’t have to, but it adds a deeper flavor. If you have time, sear the chicken in a hot skillet with a bit of olive oil for 2 to 3 minutes per side before adding to the crockpot.

What can I use instead of olives?

If you’re not an olive fan, try rinsed capers, roasted red peppers, or quartered artichoke hearts. You’ll lose some briny depth, so add an extra splash of lemon or a teaspoon of red wine vinegar.

How do I keep chicken breasts from drying out?

Use the Low setting and check early at the 3.5 to 4-hour mark.

Breasts cook faster than thighs. Shredding the meat back into the sauce also helps it stay moist.

What should I serve with this?

Couscous, orzo, rice, or polenta all work well. A side salad with cucumbers, tomatoes, and a lemony dressing balances the richness.

Don’t forget crusty bread for the sauce.

Can I add potatoes?

Yes, but cut them small (1-inch pieces) and place them at the bottom under the chicken. They’ll need the full cook time to get tender.

Is this recipe freezer-friendly?

Very. Freeze cooked portions in airtight containers.

Reheat gently with a splash of broth to bring the sauce back to life.
