Ingredient notes and substitutions

The complete list of ingredients to make this recipe is above. Below are notes about some of the ingredients, along with ideas for substitutes.

Boneless chicken breast is my preference for just about every chicken recipe I make. They are lean and easy to prepare.

You can substitute boneless skinless chicken breasts with boneless skinless chicken thighs, or use a combination of boneless thighs or breasts.

Sun-dried tomatoes not packed in oil are the best type to use when making slow-cooker Mediterranean chicken. If you only have oil-packed, you can use them, however, drain the oil off of them before adding them to the slow cooker.

Chicken broth adds flavor to this recipe, it can be substituted with an equal amount of white wine or you can mix half broth and half wine.

Garlic cloves can be replaced with 1/2 teaspoon of dried garlic powder,

Onions. You can use any type of onion in this recipe. I like to use red onion or yellow all-purpose onions.

Two teaspoons of onion powder can be substituted for fresh onions also.

Kalamata Olives add a wonderful briny flavor to this dish. If you don’t like kalamata olives, you can substitute them with regular black olives or green olives such as Castel Vetrano olives.

Serving suggestions

Serve Mediterranean chicken with a side of your favorite roasted vegetables, or green beans with a helping of mashed potatoes, farro, orzo, pasta, rice, zucchini noodles, cauliflower rice or a hunk of crusty bread.

How to store and reheat leftovers

This is the kind of recipe that tastes even better the next day, so don’t worry about having leftovers because they taste great.

Store leftover Slow Cooker Mediterranean Chicken in the refrigerator for up to four days in an airtight container.

Reheat leftover slow cooker chicken in the oven covered at 350 until it is heated through, or in a covered saucepan over low heat. You may need to add a little bit of water or wine to the pan so that it does not burn.

Recipe variations

Artichokes. Stir in 1/2 cup of quartered artichoke hearts during the last half hour of cooking.

Mediterranean Pork Tenderloin. Substitute the chicken for a one-pound pork tenderloin.

Mediterranean Chicken with Roasted Red Peppers. Add 1/4 cup of roasted red bell peppers and 1/4 cup of capers along with a spritz of lemon juice and a pinch of lemon zest.

Make it Spicy. Add 1/2 to 1 teaspoon of red pepper flakes or 1/8 teaspoon cayenne pepper.

Add Cheese. Just before serving sprinkle the chicken with a little feta cheese.

Tips

Spray the slow cooker with a little bit of cooking spray or spread a small amount of olive oil in the crockpot to keep the chicken from sticking and easy cleanup!
Just before serving slow-cooker Mediterranean chicken, remove the chicken pieces from the crockpot and mix together a slurry of 1 tablespoon of flour with 1/2 cup water. Gradually stir the slurry into the sauce in the slow cooker to thicken the sauce and serve it over the chicken.
Sear in extra flavor by quickly browning the chicken breasts in a hot skillet on top of the stove.
