This slow cooker lemon garlic chicken transforms simple ingredients into a restaurant-worthy meal with minimal effort. The tender chicken soaks up the bright citrus flavors while the slow cooking process ensures each bite remains juicy and flavorful.
I first made this dish when trying to impress my in-laws without spending all day in the kitchen. They were so impressed they asked for the recipe before leaving—now it's their go-to for entertaining as well.
Ingredients
- Boneless skinless chicken breasts: select plump pieces of even thickness for the most consistent cooking
- Olive oil: use a good quality oil as it forms the base of your sauce
- Fresh garlic: minced the aromatic heart of this dish providing depth of flavor
- Lemon juice and zest: from fresh lemons the bright acidity cuts through the richness
- Dried oregano: adds a Mediterranean earthiness that complements the lemon
- Dried thyme: brings a subtle herbaceous note that stands up to slow cooking
- Salt and pepper: enhances all the flavors and brings the dish together
- Fresh parsley: for garnish adds color and a fresh finish to the cooked dish
- Lemon slices: for serving provides visual appeal and extra flavor when squeezed over
Step-by-Step Instructions
- Create the marinade:
- Whisk together olive oil, minced garlic, lemon juice, lemon zest, oregano, thyme, salt, and pepper until fully combined. The mixture should look slightly cloudy as the oil and lemon juice emulsify. Make sure to zest your lemons before juicing them for easier handling.
- Prepare the slow cooker:
- Place the chicken breasts in an even layer at the bottom of your slow cooker. Try not to overlap them too much to ensure even cooking throughout each piece.
- Add the marinade:
- Pour the lemon garlic mixture evenly over the chicken breasts, making sure each piece is thoroughly coated. Use a spoon to scoop some of the minced garlic and herbs on top of each chicken breast.
- Slow cook:
- Set your slow cooker to low for 6-7 hours or high for 3-4 hours. The chicken is done when it reaches an internal temperature of 165°F and pulls apart easily with a fork. The slower cooking time yields more tender results.
- Serve with style:
- Transfer the chicken to a serving platter, spooning some of the sauce from the slow cooker over the top. Garnish with fresh chopped parsley and arrange lemon slices around the dish for both flavor and presentation.
The lemon zest is my secret weapon in this recipe. While many cooks discard it and just use juice, the oils in the zest contain intense citrus flavor that infuses the entire dish. My grandmother taught me this trick, and I still remember her carefully zesting lemons in her sunny kitchen, telling me "this is where the magic happens."
Make-Ahead Options
This lemon garlic chicken is perfect for meal prep. You can combine all ingredients in a freezer bag and freeze for up to three months. When ready to cook, thaw overnight in the refrigerator and then place in your slow cooker as directed. The flavors actually develop further when the chicken has time to marinate in the lemon garlic mixture before cooking.
Serving Suggestions
While this chicken is delicious on its own, it truly shines when paired with sides that complement its bright flavor profile. Serve over fluffy white rice or orzo pasta that will absorb the delicious sauce. For a lower carb option, cauliflower rice works beautifully. Add a side of steamed asparagus or broccoli to complete the meal. The sauce from the slow cooker can be spooned over everything for an extra burst of flavor.
Flavor Variations
This versatile recipe welcomes creative adaptations. For a Greek-inspired version, add 1/4 cup of Kalamata olives and 1/2 cup crumbled feta cheese during the last 30 minutes of cooking. For an Italian twist, incorporate 1 cup halved cherry tomatoes and 1 tablespoon of capers. If you enjoy heat, add 1/4 teaspoon of red pepper flakes to the marinade. Rosemary or basil can be substituted for thyme based on your preference or what you have on hand.

Recipe FAQs
- → Can I use chicken thighs instead of breasts for this dish?
Yes, boneless skinless chicken thighs work wonderfully in this dish and often result in even more tender meat. They typically contain more fat which helps them stay juicy during the long cooking process. You may need to adjust cooking time slightly, but the flavor will be excellent.
- → What side dishes pair well with lemon garlic chicken?
This chicken pairs beautifully with rice or couscous to absorb the flavorful sauce. Roasted vegetables like asparagus, broccoli, or green beans complement the lemony flavors. A light Greek salad or simple garden salad also makes for a refreshing accompaniment.
- → Can I prepare this dish ahead of time?
Absolutely! You can mix the marinade the night before and store it separately in the refrigerator. In the morning, simply place the chicken in the slow cooker, pour the marinade over it, and start cooking. You can also fully cook the dish and refrigerate for up to 3 days, reheating gently when ready to serve.
- → How can I make the sauce thicker?
If you prefer a thicker sauce, you can remove the chicken once cooked and transfer the liquid to a saucepan. Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water, then whisk into the sauce. Simmer for 3-5 minutes until thickened to your liking, then pour over the chicken before serving.
- → Can I freeze this lemon garlic chicken?
Yes, this dish freezes well. Allow it to cool completely, then transfer to airtight containers or freezer bags. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or microwave until warmed through. The sauce may separate slightly, but a quick stir will recombine it.
- → Is there a way to make this dish without a slow cooker?
Certainly! You can marinate the chicken in the lemon-garlic mixture for at least 30 minutes, then bake in a covered dish at 350°F (175°C) for about 25-30 minutes until the chicken reaches 165°F (74°C) internally. Alternatively, you can simmer it covered on the stovetop over low heat for about 20-25 minutes until cooked through.
