Crockpot Lemon Garlic Boneless Skinless Chicken Thighs

These crockpot lemon garlic boneless skinless chicken thighs cook on low for 3 to 4 hours in butter, lemon zest, lemon juice and six cloves of garlic, and the juices get thickened into a sauce at the end.

The thickening step is what sets this version apart.

Most slow cooker lemon chicken recipes leave you with tender thighs sitting in a puddle of thin, watery liquid, so this one finishes with a quick cornstarch slurry that turns that liquid into a glossy butter sauce you can actually spoon over rice.

The whole thing takes about 4 hours, and almost none of that is hands-on.

Boneless skinless thighs are the right cut here because they stay moist on a short cook and have no skin to go flabby.

Ingredients

For the Chicken

3 lb boneless skinless chicken thighs (about 8 thighs)

1 1/2 teaspoons kosher salt

1 teaspoon paprika

1 teaspoon dried oregano

1/2 teaspoon onion powder

1/2 teaspoon black pepper

1/4 teaspoon red pepper flakes (optional)

For the Lemon Garlic Sauce

6 cloves garlic, minced (about 2 tablespoons)

1 tablespoon lemon zest (from 1 large lemon)

3 tablespoons fresh lemon juice (from 1 to 2 lemons)

1/4 cup low-sodium chicken broth

4 tablespoons salted butter, cut into 8 pieces

1 tablespoon cornstarch

2 tablespoons cold water

2 tablespoons chopped fresh parsley

Lemon slices, for serving (optional)

Steps

1. Pat the thighs dry with paper towels so the seasoning sticks instead of sliding off in the juices.

2. Stir the salt, paprika, oregano, onion powder, black pepper and red pepper flakes together in a small bowl, then rub the mix over both sides of every thigh.

3. Lay the thighs in a 6-quart slow cooker in a mostly single layer, overlapping a little where you have to.

4. Zest the lemon with a microplane zester before you juice it, taking only the yellow part and none of the bitter white pith.

5. Scatter the minced garlic and lemon zest over the chicken, then pour the lemon juice and chicken broth around the edges so the seasoning on top stays put.

6. Dot the butter pieces over the thighs.

7. Cover and cook on low for 3 to 4 hours, until the thickest thigh reads 175°F (79°C) on an instant-read thermometer.

8. Check at the 3-hour mark, because boneless thighs go from tender to stringy somewhere past 5 hours, and the lid can stay off for the 30 seconds it takes to test.

9. Move the thighs to a plate and cover them loosely with foil.

10. Turn the slow cooker to high, whisk the cornstarch and cold water together in a small cup until smooth, and stir the slurry into the juices.

11. Cover and cook on high for 10 to 15 minutes, stirring once, until the sauce turns glossy and coats a spoon.

12. If you want it faster, pour the juices into a small saucepan instead and simmer with the slurry over medium heat for 2 to 3 minutes.

13. Return the thighs to the sauce, turn them to coat, and top with the parsley and lemon slices.

Helpful Tips & Substitutions

Use both zest and juice, because they do different jobs: zest carries the lemon oil and aroma through 4 hours of cooking, while juice on its own just turns the sauce sharp.

If you want a brighter finish, hold back 1 tablespoon of the lemon juice and stir it in with the parsley at the very end.

Do not add more liquid than the 1/4 cup of broth, because the thighs release close to a cup of their own juices and anything extra just dilutes the butter and garlic.

Fresh garlic matters here, since jarred minced garlic tastes flat and slightly sour after a long cook.

Unsalted butter works if that is what you have, but add another 1/4 teaspoon of salt to the rub.

Boneless skinless chicken breasts can stand in, but cook them on low for 2 1/2 to 3 hours and pull them at 165°F (74°C), because breasts dry out past that point in a way thighs never do.

Always mix the cornstarch with cold water before it goes in, since dry cornstarch stirred into hot liquid seizes into lumps that never dissolve.

Italian seasoning can replace the oregano one for one, and a teaspoon of dried thyme is a good swap if you want it less pizza-adjacent.

For a creamier sauce, whisk 1/4 cup heavy cream into the thickened juices right before the chicken goes back in.

Serving Ideas

Spoon the thighs and sauce over white rice, since the rice soaks up the butter and lemon better than anything else.

Mashed potatoes work just as well, and the 10 crockpot potato sides for weeknight dinners has a couple you can run in a second cooker alongside this one.

For a garlic-on-garlic dinner, serve the chicken sliced over crockpot creamy garlic pasta with extra lemon squeezed over the top.

Steamed green beans or broccoli tossed in a spoonful of the sauce are the fastest vegetable side.

If you want the same hands-off format with vegetables cooked in the pot, the crockpot garlic herb butter chicken with veggies is the one to make on a different night.

Leftover thighs slice well cold into a salad with cucumber, feta and the leftover sauce whisked with a little olive oil as the dressing.

Make-Ahead & Storage

You can season the thighs and mix the garlic, zest and juice up to 24 hours ahead, then keep everything covered in the fridge and load the slow cooker in the morning.

Do not zest more than a day ahead, because the zest dries out and loses most of its aroma.

Leftovers keep 4 days in the fridge in glass meal prep containers, with the sauce stored over the chicken so the meat does not dry out.

The sauce firms up when cold because of the butter and cornstarch, so reheat in a covered skillet over medium-low with a tablespoon of water per serving until it loosens.

The microwave works too, in 1-minute bursts at 70 percent power, stirring between rounds.

Freeze the chicken and sauce together in a gallon freezer bag pressed flat for up to 3 months.

The butter sauce can look separated after thawing, so whisk it as it reheats and it comes back together.

Thaw overnight in the fridge rather than on the counter, since chicken should never sit above 40°F (4°C) for more than 2 hours.

The sauce is the part people ask about, and it comes entirely from the thigh juices, butter and that one tablespoon of cornstarch.

By the second day the garlic has mellowed into the butter and the lemon tastes rounder, which is why the leftovers over rice are often better than the first plate.
