Step-by-Step Instructions

Making Slow Cooker Mediterranean Chicken is a breeze, with just a few steps to create a flavorful, hands-off meal. Follow these steps for a delicious result.

Step 1: Prep the Chicken

Pat 4 boneless, skinless chicken breasts dry with paper towels.
Season both sides with a pinch of salt, pepper, 1 tsp dried oregano, 1 tsp dried basil, and ½ tsp red pepper flakes (if using).
Place the chicken breasts in the slow cooker in a single layer.
Tip: Trim any excess fat from the chicken for a cleaner dish.

Step 2: Add the Sauce Ingredients

Pour 1 can (14 oz) undrained diced tomatoes over the chicken.
Add 1 cup pitted and halved Kalamata olives, ½ cup sliced red onion, and 4 minced garlic cloves on top.
Gently stir to distribute the ingredients, ensuring the chicken is partially covered by the tomatoes.
Tip: Spread the olives and onions evenly to avoid clumping.

Step 3: Cook

Cover and cook on low for 6–7 hours or high for 3–4 hours, until the chicken is tender and reaches an internal temperature of 165°F (74°C).
Check doneness at the lower end of the time to avoid overcooking, as slow cookers vary.
Tip: Avoid lifting the lid during cooking to maintain consistent heat.

Step 4: Serve

Carefully transfer the chicken to a serving platter or plates, shredding it slightly with two forks if desired for easier eating.
Spoon the tomato-olive sauce over the chicken, ensuring each serving gets plenty of olives, onions, and juices.
Garnish with chopped fresh parsley and serve over cooked couscous or quinoa.
Tip: If the sauce is too thin, simmer it in a saucepan for 5–7 minutes to reduce, or thicken with a slurry of 1 tsp cornstarch and 1 tbsp water.

Assembly

Assembling Slow Cooker Mediterranean Chicken is all about creating a vibrant, flavorful plate. Here’s how to bring it together:

Choose Your Base: Serve the chicken and sauce over a bed of fluffy couscous or quinoa to soak up the tangy, savory juices. Cauliflower rice or roasted vegetables work for a low-carb option.
Add the Chicken and Sauce: Place a chicken breast (whole or shredded) on each plate, spooning a generous amount of the tomato-olive sauce over the top, including olives and onions.
Garnish: Sprinkle with chopped fresh parsley for a fresh, colorful finish.
Presentation Tips:
- Use wide, shallow bowls to showcase the vibrant red sauce and colorful olives.
- Arrange the chicken slightly off-center with the sauce cascading over for a rustic, Mediterranean look.
- Pair with a side of Greek salad, roasted zucchini, or pita bread for a complete Mediterranean meal.

Tip: For a family-style presentation, serve the chicken and sauce in a large dish with couscous or quinoa on the side, letting everyone help themselves.

Storage and Make-Ahead Tips

Keep your Slow Cooker Mediterranean Chicken fresh and ready to enjoy with these tips:

Storing Leftovers:
- Store cooled chicken and sauce in an airtight container in the fridge for up to 3–4 days.
- Reheating: Reheat in the microwave (1–2 minutes, stirring halfway) or on the stovetop over low heat, adding a splash of broth or water to loosen the sauce. Reheat only the portion you need.
Make-Ahead Tips:
- Ingredients: Prep the red onion, garlic, and olives up to 2 days in advance and store in the fridge.
- Chicken: Season the chicken up to 1 day ahead and refrigerate. Combine with sauce ingredients when ready to cook.
- Assembly: Place all ingredients in the slow cooker insert the night before, cover, and refrigerate. Start cooking in the morning.
- Full Dish: Cook the entire dish a day ahead; flavors deepen overnight. Reheat gently before serving.
Freezing: Freeze cooled chicken and sauce (without garnish) in a freezer-safe container for up to 3 months. Thaw in the fridge overnight and reheat with a splash of broth to restore texture. Couscous/quinoa should be prepared fresh.

Tip: Use leftovers in wraps, over pasta, or as a topping for flatbread pizzas with extra olives and feta.

Recipe Variations

Slow Cooker Mediterranean Chicken is versatile and easy to customize. Try these creative twists:

Veggie Boost: Add artichoke hearts, zucchini, or cherry tomatoes in the last hour for extra Mediterranean flair.
Spicy Kick: Increase red pepper flakes to 1 tsp or add a diced fresh chili for more heat.
Creamy Twist: Stir in ½ cup crumbled feta or Greek yogurt at the end for a creamy, tangy finish.
Herb Swap: Replace oregano and basil with rosemary, thyme, or a Mediterranean herb blend for a different flavor profile.
Protein Swap: Use shrimp (cook for 2–3 hours on low) or chickpeas for a vegetarian version, adjusting cooking time as needed.

Tip: Keep the olives and tomatoes as the core Mediterranean elements, but adjust herbs or proteins to suit your taste.
