How to Make Mediterranean Crockpot Lemon Herb Chicken
Step 1: Prepare the Chicken
Season the chicken with salt and pepper to taste. Heat a large skillet over medium-high heat and sear the chicken for 1-2 minutes on each side until golden brown. Transfer the seared chicken into a greased slow cooker.
Step 2: Add Remaining Ingredients
Arrange the chopped onions, kalamata olives, roasted red peppers, and capers around the chicken in the slow cooker, ensuring these toppings stay on the sides and don’t completely cover the chicken.
Step 3: Whisk and Pour
In a small bowl, whisk together the Italian seasoning, fresh lemon juice, and minced garlic. Pour this mixture evenly over the chicken.
Step 4: Cook to Perfection
Cover the slow cooker and set it to cook on low for 4 hours or on high for 2 hours, or until the chicken is fully cooked and tender.
Step 5: Serve
Once cooked, garnish with fresh thyme, oregano, or basil if desired. Serve the chicken hot, paired with your favorite Mediterranean sides. If you’re looking for a side dish idea, try our Mediterranean pasta salad with whipped feta.
