Ingredients You Need

Chicken

2 to 2.5 pounds boneless skinless chicken thighs
- Thighs stay juicy and forgiving in the slow cooker.
- Use boneless skinless chicken breasts if you prefer leaner meat, but check for doneness a bit earlier so they do not dry out.

Vegetables

1.5 pounds baby potatoes, halved
- Use Yukon gold or red potatoes for a creamy texture.
- If you only have large russet potatoes, peel them and cut into 1.5 inch chunks so they cook evenly.
3 to 4 large carrots, peeled and cut into 1 inch chunks
- Baby carrots also work; just toss them in whole.
1 medium yellow onion, sliced thick
- Sweet onion works too and adds a mild sweetness.
1 cup fresh green beans, trimmed and cut in half
- Use frozen green beans in a pinch and add them during the last hour so they do not turn mushy.

Garlic Butter Sauce

8 tablespoons (1 stick) unsalted butter, melted
- Use salted butter and reduce the added salt slightly.
- I like a good quality butter like Kerrygold or a store brand European style butter for richer flavor.
6 to 8 cloves garlic, minced or pressed
- Use jarred minced garlic from the fridge if you need a shortcut, about 2 to 3 teaspoons.
1 teaspoon kosher salt
- If you use table salt, start with 1/2 teaspoon and adjust at the end.
1/2 teaspoon black pepper
1 teaspoon dried Italian seasoning
- Or use a mix of dried oregano, basil, and thyme.
1/2 teaspoon smoked paprika or regular paprika
- Smoked paprika adds a subtle smoky note that tastes amazing with butter.
Juice of 1/2 lemon (about 1 tablespoon)
- Bottled lemon juice works if that is what you have.
2 tablespoons low sodium chicken broth or water
- This keeps the sauce from turning too thick and helps everything cook evenly.

Optional Finishing Touches

2 tablespoons chopped fresh parsley
Extra lemon wedges for serving
Grated Parmesan for sprinkling over the veggies

Pantry Shortcuts

Use pre-peeled garlic or jarred minced garlic.
Use pre-cut carrot sticks and bagged baby potatoes to cut prep time.
Use frozen green beans or a frozen mixed veggie blend and stir in near the end.

Equipment

5 to 7 quart slow cooker
Cutting board and sharp knife
Small bowl for mixing the garlic butter
Measuring spoons and cup
Tongs or a large spoon for serving

Tips & Mistakes

Cut potatoes and carrots into similar size chunks so they cook at the same rate.
Place potatoes and carrots on the bottom of the slow cooker since they need more heat and time.
Avoid stacking chicken in a huge pile; spread it out so each piece cooks evenly.
Melt the butter gently so it does not brown unless you want a nutty flavor.
Taste the garlic butter before you pour it and adjust salt, pepper, and lemon to your liking.
Do not skimp on the garlic; the slow cooker softens the sharpness and gives a mellow flavor.
Use low heat for the most tender chicken; high heat can make it a bit tougher.
Add green beans during the last 45 to 60 minutes so they stay bright and not mushy.
Resist the urge to open the lid often; each peek drops the temperature and extends cook time.
Check chicken for doneness near the end; it should reach 165°F and feel tender when you pierce it.
Stir gently before serving so the garlic butter coats every veggie and piece of chicken.
Let the dish sit for 5 minutes after cooking so the juices settle and the sauce thickens slightly.

How to Make Slow Cooker Garlic Butter Chicken and Veggies

Step 1: Prep the Vegetables

Wash and halve the baby potatoes. Peel and chop the carrots into 1 inch pieces and slice the onion into thick wedges. Add potatoes, carrots, and onion to the bottom of the slow cooker in an even layer.

Step 2: Season the Chicken

Pat the chicken thighs dry with paper towels so the seasoning sticks. Sprinkle both sides with a pinch of salt and pepper. Lay the chicken on top of the veggies in a single layer as much as possible.

Step 3: Mix the Garlic Butter

In a small bowl, combine melted butter, minced garlic, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, Italian seasoning, paprika, lemon juice, and chicken broth or water. Whisk until the mixture looks smooth and the seasonings distribute evenly. Taste a tiny bit and adjust salt or lemon if you want more punch.

Step 4: Add Sauce and Start Cooking

Pour the garlic butter mixture evenly over the chicken and veggies. Tilt the slow cooker slightly if needed so the sauce reaches all sides. Cover with the lid.

Step 5: Choose Your Cook Time

Cook on low for 4.5 to 6 hours, depending on your slow cooker and the thickness of your chicken. Or cook on high for about 3 to 3.5 hours if you need it sooner. Check the chicken around the earlier time mark and continue until it reaches 165°F and feels tender.

Step 6: Add Green Beans

About 45 to 60 minutes before the end of cooking, lift the lid quickly and add the green beans on top. Spoon a little of the garlic butter sauce over them. Cover again and finish cooking until the green beans turn tender but still keep some bite.

Step 7: Finish and Adjust Seasoning

Once the chicken and veggies reach your preferred tenderness, turn off the slow cooker. Gently stir everything so the garlic butter coats each piece. Taste the sauce and sprinkle in a bit more salt, pepper, or lemon juice if needed.

Step 8: Garnish and Serve

Sprinkle chopped fresh parsley over the top. Add a light shower of grated Parmesan if you want extra richness. Serve hot with extra lemon wedges on the side.

Variations I've Tried

Use bone-in chicken thighs and increase the cook time by about 30 to 45 minutes on low. The bones add extra flavor and the meat tastes even richer. Just make sure the thickest part of the meat reaches 165°F.

Swap the potatoes for cauliflower florets and extra carrots for a lower carb version. Add the cauliflower during the last 2 hours on low so it does not fall apart. The garlic butter clings to the cauliflower and tastes almost like roasted veggies.

Try a ranch twist and replace the Italian seasoning with 1 tablespoon dry ranch seasoning mix. Reduce the salt slightly since ranch mix already contains salt. This version tastes especially good with extra carrots and green beans.

Use sweet potatoes instead of regular potatoes for a slightly sweet and savory combo. Cut them into 1 inch chunks and keep them on the bottom with the carrots. The sweetness pairs nicely with the garlic and paprika.

How to Serve Slow Cooker Garlic Butter Chicken and Veggies

Serve the chicken and veggies straight from the slow cooker with a big spoon so everyone gets plenty of sauce. Spoon extra garlic butter over each plate for maximum flavor. Pair it with a simple green salad, steamed rice, or warm crusty bread to soak up the buttery juices. Add lemon wedges and a sprinkle of fresh herbs at the table so people can customize their plate.

How to store

Cool leftovers until they reach room temperature, then transfer to airtight containers.
Store in the fridge for up to 3 to 4 days.
Freeze portions in freezer-safe containers or bags for up to 2 months.
Reheat gently in a covered skillet over low heat with a splash of broth or water until hot, or use the microwave in short bursts, stirring between each burst so the chicken stays tender and the veggies do not overcook.
