Ingredients

• 1 cup roasted red bell peppers, divided
• 2 cups tomato sauce
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1 teaspoon sugar
• 1/2 teaspoon crushed red pepper flakes
• 5 each chicken thighs
• 1/2 teaspoon Kosher salt
• 1/4 teaspoon cracked pepper

Prep notes

Plan about 6 to 8 hours on low or 3 to 4 hours on high for cooking time, depending on your slow cooker and how tender you like the chicken. If you prefer a thicker sauce, remove the lid for the last 30 minutes of cooking or transfer the sauce to a saucepan and simmer briefly. Use a slotted spoon to remove olives or artichokes for picky eaters and reserve them on the side if desired.

Step-by-step directions

Follow these clarified steps to achieve the best results while keeping the original ingredient amounts and order in mind.

1. Prepare your slow cooker by ensuring it is clean and dry, then set it on a stable surface. If your slow cooker has a removable insert, place it in the base.
2. Place 1/2 cup of the roasted red bell peppers into the bottom of the slow cooker. Spread them out so they form a thin layer. Reserve the remaining roasted red bell peppers to add later.
3. Pour 2 cups of tomato sauce over the roasted red bell peppers in the slow cooker.
4. Sprinkle 1 teaspoon dried oregano and 1 teaspoon dried basil evenly over the tomato sauce. Add 1 teaspoon sugar and 1/2 teaspoon crushed red pepper flakes to the sauce layer.
5. Stir the sauce and seasonings gently in the slow cooker to combine them. This helps distribute the herbs and sugar evenly before adding the chicken.
6. Pat the 5 chicken thighs dry with paper towels. Season both sides of each thigh with 1/2 teaspoon Kosher salt distributed across the pieces and 1/4 teaspoon cracked pepper. Place the seasoned chicken thighs into the slow cooker on top of the sauce in a single layer. If necessary, nestle pieces so they fit comfortably.
7. Scatter 1/2 cup artichoke hearts and 1/2 cup kalamata olives over and around the chicken thighs. Distribute them so each chicken thigh will have some artichokes and olives nearby for flavor.
8. Add the remaining 1/2 cup roasted red bell peppers on top of the chicken and vegetables. This keeps some of the peppers closer to the surface so they soften without overcooking.
9. Cover the slow cooker with its lid and set to cook. For best results, cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the chicken thighs register at least 165°F (74°C) and are very tender.
10. Once the chicken is fully cooked, carefully remove the lid, watching for steam. Optionally, remove the chicken to a serving platter and spoon the sauce, peppers, artichokes, and olives over the top. If you prefer a thicker sauce, transfer some of the sauce to a saucepan and simmer gently for 5 to 10 minutes to reduce, then return it to the slow cooker or pour over the chicken.
11. Taste the sauce and adjust seasoning if needed, adding a pinch more salt or a squeeze of lemon if you want extra brightness. Serve the chicken hot with your choice of sides.

Troubleshooting & tips

• If your slow cooker runs hot, check for doneness toward the lower end of the suggested cooking window to avoid overcooking the chicken thighs.
• For a creamier variation, stir in a few tablespoons of plain yogurt or a splash of cream right before serving, warming through briefly.
• To keep the sauce vibrant, add a handful of fresh chopped parsley or basil right before serving.
• If you prefer less heat, reduce the crushed red pepper flakes to 1/4 teaspoon or omit entirely.
• Make-ahead: prepare through step 8, refrigerate up to 24 hours, then cook from chilled on low for 7 to 9 hours or on high for 4 to 5 hours, adding a little extra time if necessary.

Serving suggestions

This Slow Cooker Mediterranean Chicken is wonderfully versatile. Here are a few ways to serve it:

• Over fluffy couscous with a drizzle of olive oil and a sprinkle of lemon zest to brighten the dish.
• With steamed basmati or jasmine rice to soak up the savory tomato sauce.
• Alongside roasted or steamed vegetables for a lighter plate.
• With warm crusty bread or pita for dunking and enjoying every last bit of sauce.

Make it a meal plan staple

Leftovers transform into quick lunches—tuck the shredded chicken and sauce into wraps or fold into a grain bowl with fresh cucumber, cherry tomatoes, and a dollop of yogurt. The dish freezes well: cool completely, portion into airtight containers, and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stove or in the microwave.

Flavor variations

• Smoky twist: add 1/2 teaspoon smoked paprika for a subtle smoky depth.
• Herb-forward: stir in 1 tablespoon chopped fresh oregano and 1 tablespoon chopped fresh basil near the end of cooking for a herbier finish.
• Vegetable boost: toss in a cup of sliced mushrooms or quartered zucchini at the start for extra veggies.
• Spicy kick: increase the crushed red pepper flakes to 1 teaspoon or add a chopped jalapeño to the sauce.

Notes on ingredients

Roasted red bell peppers can be store-bought from a jar or homemade—either works. Use plain tomato sauce without added meat stocks to keep the flavor profile clean and suited to the recipe. The artichoke hearts can be jarred or canned; if canned, drain and rinse them before adding. Choose pitted kalamata olives for convenience, halved if large. The recipe uses chicken thighs for their forgiving nature and rich texture; bone-in or boneless thighs can be used according to preference.

Nutrition snapshot (per serving, approximate)

This depends on portion size and specific ingredient brands, but a generous estimate per serving includes moderate protein from the chicken, moderate fat mainly from the chicken thighs and olives, and carbohydrates from the tomato sauce and any sides you serve with it. To lower the fat, use leaner cuts or trim excess skin; to boost fiber, serve over whole grains or a hearty salad.
