Ingredients

For the base:

2.5–3 pounds bone-in, skinless chicken thighs (or use boneless thighs for less fat)
1.5 pounds baby potatoes, halved if large (Yukon gold or red work well)
1 cup low-sodium chicken broth

For the sauce:

6 tablespoons unsalted butter, cut into pieces
6 cloves garlic, minced (about 2 tablespoons)
1 cup grated Parmesan cheese (freshly grated if possible)
1 teaspoon Italian seasoning
1 teaspoon kosher salt (adjust to taste)
1/2 teaspoon black pepper
1 tablespoon lemon juice (fresh)
1 tablespoon cornstarch mixed with 1 tablespoon water (optional, for thicker sauce)

Garnish:

2 tablespoons chopped fresh parsley (optional)
Lemon wedges for serving (optional)

Notes: If using salted butter, reduce added salt. Freshly grated Parmesan melts better and tastes brighter.

How to Make Slow Cooker Garlic Parmesan Chicken and Potatoes

Prep the slow cooker and ingredients: spray the insert with nonstick spray or rub with a little oil. Mince garlic, halve large potatoes, and pat chicken dry. (Why this matters: a lightly oiled pot prevents sticking and makes cleanup easier.)
Season the chicken: rub thighs with salt, pepper, and half the Italian seasoning. Place the chicken skin-side up in the slow cooker.
Add potatoes: tuck the potatoes around and under the chicken so they soak up the juices.
Make the sauce: in a bowl, whisk together melted butter, minced garlic, chicken broth, lemon juice, remaining Italian seasoning, and half the Parmesan. Pour the mixture over the chicken and potatoes. (Mini-tip: the lemon brightens the sauce and prevents it from tasting too heavy.)
Cook low and slow: cover and cook on LOW for 4–6 hours, or on HIGH for 2–3 hours, until the chicken reaches 165°F and potatoes are tender. Avoid lifting the lid too often.
Finish the sauce: about 15 minutes before serving, remove 1/4 cup of cooking liquid into a small bowl and whisk in the cornstarch slurry if you want a thicker sauce; stir it back into the slow cooker. Sprinkle the remaining Parmesan over the chicken and potatoes, then cover for the final 10–15 minutes so the cheese melts into the sauce. (Why this step matters: adding Parmesan at the end keeps it creamy and helps form a glossy coating.)
Rest and garnish: let the dish sit for 5 minutes, then sprinkle with chopped parsley and serve with lemon wedges.

How to Serve Slow Cooker Garlic Parmesan Chicken and Potatoes

Plate the chicken and potatoes with a spoonful of the garlicky sauce over the top and a sprinkle of fresh parsley.
Serve with a simple green salad or steamed green beans for color and crunch.
Offer crusty bread or warm rolls to mop up the sauce and complete the meal.

How to Store Slow Cooker Garlic Parmesan Chicken and Potatoes

Fridge: Cool to room temperature, then store in an airtight container for up to 3 days.
Freezer: Freeze in a freezer-safe container for up to 2 months (texture of potatoes may soften). Thaw overnight in the fridge before reheating.
To reheat: Warm in a covered oven-safe dish at 325°F for 15–20 minutes, or microwave single portions until hot. Add a tablespoon of chicken broth if the sauce seems dry.

Tips to Make Slow Cooker Garlic Parmesan Chicken and Potatoes

Use chicken thighs for juicier meat; breasts can dry out if overcooked.
Cut potatoes evenly so they cook at the same rate.
If you want crisp skin, broil the chicken on a baking sheet for 2–3 minutes after slow cooking.
Taste before serving and adjust salt or lemon if the sauce needs brightness.

Variation (if any)

Gluten-free: Use cornstarch or a gluten-free thickener and check that your Parmesan is gluten-free.
Lighter: Swap half the butter for olive oil, and use boneless chicken breasts—watch cooking time to avoid dryness.
Vegetarian swap: Replace chicken with large portobello caps or cauliflower steaks and use vegetable broth; cook until vegetables are tender.

FAQs

Can I use frozen chicken?

Yes, but thawing first gives more even cooking. If you must use frozen, add extra cooking time and check the internal temperature to be safe.

Can I use chicken breasts instead of thighs?

Yes. Boneless breasts work but check them at the shorter end of the cooking time to avoid dryness. Consider a little extra broth or butter.

How do I make the sauce thicker?

Stir a cornstarch slurry (1 tbsp cornstarch + 1 tbsp cold water) into a small amount of hot cooking liquid, then mix back into the slow cooker and cook 10–15 minutes more.

What if my potatoes are still firm?

Cut potatoes smaller next time or cook on LOW a bit longer. You can remove the chicken early and keep it warm while the potatoes finish.
