Prepare Ingredients: Start by mincing the garlic and squeezing the juice from the lemons, ensuring you have all your ingredients ready before cooking begins.
Sear the Chicken: In a skillet over medium-high heat, add olive oil and season the chicken breasts with salt and pepper. Sear each piece until golden brown on both sides.
Layer Ingredients in Crockpot: Place the seared chicken breasts in your crockpot, then top them with minced garlic and capers. Pour in chicken broth and lemon juice.
Season and Cook: Sprinkle Italian seasoning over the top, cover, and set to cook on low for 6 hours or high for 3 hours until the chicken is tender.
Create the Sauce: Once cooked, remove the chicken and whisk in butter into the remaining juices until smooth.
Serve and Enjoy: Plate your chicken with sauce drizzled on top, served over pasta or rice if desired, and garnish with chopped parsley.
