Ingredients you’ll need
- Boneless, skinless chicken breasts or thighs
- Garlic (fresh is best here)
- Lemons (zest + juice)
- Chicken broth
- Olive oil or melted butter
- Dijon mustard (optional, but adds body and flavor)
- Italian seasoning or oregano + thyme
- Salt and black pepper
- Cornstarch (optional, for thickening)
- Fresh parsley (optional for serving)
How to make slow cooker chicken with lemon garlic sauce
1) Build the sauce. In a bowl, whisk chicken broth, lemon juice, lemon zest, garlic, olive oil (or butter), seasonings, salt, pepper, and Dijon if using.
2) Add chicken. Place chicken in the slow cooker and pour the sauce over the top. Turn chicken to coat.
3) Slow cook. Cook on LOW until the chicken is tender (best for juicy results). Avoid overcooking, especially with chicken breasts.
4) Finish the sauce (optional). If you want a thicker sauce, remove the chicken and whisk a cornstarch slurry into the hot liquid. Cover and cook a few minutes until glossy and lightly thickened.
5) Serve. Spoon lemon garlic sauce over the chicken and garnish with parsley if you like.
Slow cooker times (breasts vs thighs)
- Chicken breasts: cook on LOW until just done and easy to slice/shred. (They dry out faster, so check earlier.)
- Chicken thighs: more forgiving and stay juicy longer; great if dinner timing is flexible.
Tips for the best lemon garlic sauce
- Use zest: lemon zest adds big flavor without extra acidity.
- Don’t drown it: keep liquid moderate so the sauce tastes concentrated, not watery.
- Thicken at the end: a quick cornstarch slurry gives you a silky sauce that clings to the chicken.
- Balance the tang: if your lemons are extra sharp, a small pat of butter or drizzle of honey can round it out.
What to serve with lemon garlic chicken
- Steamed rice, cauliflower rice, or orzo
- Mashed potatoes or roasted baby potatoes
- Pasta or buttered egg noodles
- Roasted broccoli, green beans, asparagus, or a simple salad
- Crusty bread to mop up the sauce
Storage and reheating
- Refrigerator: store chicken and sauce in an airtight container for up to 4 days.
- Freezer: freeze cooled chicken in sauce for up to 3 months.
- Reheat: warm gently on the stovetop or microwave in short bursts. Add a splash of broth if the sauce thickened too much.
Frequently asked questions
- Can I use frozen chicken? For food safety, it’s best to thaw first so the chicken heats quickly and evenly in the slow cooker.
- Can I add veggies? Yes—add hearty veggies (like baby potatoes or carrots) at the start. Add quick-cooking veggies (like spinach) near the end.
- Is it very lemony? It’s bright and garlicky. For a milder lemon flavor, reduce the juice slightly and keep the zest.
