Ingredients You’ll Need

Chicken

2 to 3 pounds boneless skinless chicken thighs
- Use thighs for juicy, tender meat that stays moist in the slow cooker.
- Swap with boneless skinless chicken breasts if you prefer leaner meat, and check them a bit earlier so they do not dry out.

Vegetables

1.5 pounds baby potatoes, halved
- Use gold or red potatoes; they hold shape and stay creamy.
- If you only have russet potatoes, peel them and cut into 1.5 inch chunks.
3 to 4 large carrots, peeled and cut into 1 inch chunks
- Baby carrots also work; keep them whole or cut thick ones in half.
8 ounces fresh green beans, trimmed
- Frozen green beans work in a pinch; add them in the last hour so they do not turn mushy.
1 small yellow onion, sliced
- Use sweet onion if you like a milder flavor.

Garlic Butter Sauce

8 tablespoons (1 stick) unsalted butter, melted
- Use salted butter and reduce added salt slightly if that is what you have.
- I like a good quality American or European-style butter since it adds richer flavor.
6 to 8 garlic cloves, minced or pressed
- Use jarred minced garlic as a shortcut; 1.5 teaspoons equals about 1 clove.
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper
1 teaspoon dried Italian seasoning
- Or mix ½ teaspoon dried basil, ¼ teaspoon dried oregano, ¼ teaspoon dried thyme.
½ teaspoon smoked paprika or sweet paprika
Juice of ½ lemon (about 1 tablespoon)
- Bottled lemon juice works when fresh lemons hide from you.
2 tablespoons fresh parsley, chopped, for serving
- Dried parsley works in a pinch; use 2 teaspoons and stir it into the sauce.

Optional Add-ins

½ teaspoon onion powder for extra savory flavor
¼ teaspoon crushed red pepper flakes for gentle heat
½ cup low sodium chicken broth if you want more sauce for spooning over rice or pasta

Pantry Shortcuts & Brand Notes

Use pre-peeled garlic or jarred minced garlic on busy days.
Grab a bag of pre-washed baby carrots and baby potatoes to cut prep time.
Any reliable store brand butter and broth works; just choose low sodium broth so the dish does not taste too salty.

Equipment List

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

Tips & Tricks

Cut potatoes and carrots into similar sizes so they cook evenly.
Place potatoes and carrots on the bottom of the slow cooker since they need more heat.
Use chicken thighs if you want the juiciest result; use breasts if you prefer lean meat and shorten the cook time slightly.
Melt the butter gently so it does not brown unless you want a nutty flavor.
Taste the garlic butter sauce before you pour it in and adjust salt, pepper, or lemon.
Add green beans in the last 45 to 60 minutes so they stay bright and tender-crisp.
Avoid lifting the lid often since that drops the temperature and extends cook time.
Check doneness with a thermometer; aim for 165°F in the thickest part of the chicken.
Stir gently near the end to coat all veggies in the garlic butter without breaking them up.
Garnish with fresh parsley or chives right before serving for color and freshness.

How to Make Slow Cooker Garlic Butter Chicken and Veggies

Step 1: Prep the Vegetables

Wash and halve the baby potatoes. Peel and slice the carrots into thick chunks, then slice the onion. Trim the green beans, but set them aside for later if you plan to add them near the end.

Step 2: Layer the Veggies in the Slow Cooker

Place potatoes in an even layer on the bottom of the slow cooker. Add carrots and onion on top of the potatoes. Sprinkle with a pinch of salt and pepper to season the vegetables from the start.

Step 3: Add the Chicken

Pat the chicken dry with paper towels so the sauce sticks better. Lay the chicken pieces in a single layer over the vegetables. Season both sides lightly with salt and pepper.

Step 4: Mix the Garlic Butter Sauce

In a small bowl, combine melted butter, minced garlic, Italian seasoning, paprika, lemon juice, and any optional onion powder or red pepper flakes. Whisk until the mixture looks smooth and the garlic spreads evenly. Taste and adjust seasoning with a little more salt or lemon if needed.

Step 5: Pour the Sauce and Add Broth if Using

Pour the garlic butter sauce evenly over the chicken and vegetables. Tilt the slow cooker slightly and spoon some sauce over any dry spots. Add chicken broth around the edges if you want extra sauce, not directly over the top so you keep the butter flavor strong.

Step 6: Cook Low and Slow

Cover the slow cooker with the lid. Cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the chicken reaches 165°F and the potatoes feel tender when you pierce them with a fork. Avoid opening the lid more than once or twice so the heat stays consistent.

Step 7: Add Green Beans Near the End

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

Step 8: Finish and Serve

Taste the sauce and veggies and adjust with a pinch of salt, pepper, or a squeeze of extra lemon. Sprinkle chopped fresh parsley over the chicken and vegetables. Serve the Slow Cooker Garlic Butter Chicken and Veggies straight from the crock with plenty of sauce spooned over each plate.

What to Serve with Slow Cooker Garlic Butter Chicken and Veggies

This Slow Cooker Garlic Butter Chicken and Veggies already counts as a full meal, but a simple side rounds it out nicely. Serve it over fluffy white rice, brown rice, or buttery mashed potatoes to soak up every drop of garlic butter. Add a crisp green salad or sliced cucumbers and tomatoes for freshness and crunch. Pair it with iced tea, sparkling water, or a citrusy lemonade for a family-friendly dinner.

Storage Options

Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
Cool everything completely before you transfer it to containers so condensation does not water down the sauce.
Freeze portions in freezer-safe containers or bags for up to 2 months, and label with the date.
Reheat gently in a covered skillet over low heat with a splash of broth or water, or use the microwave in short bursts, stirring between each round so the chicken stays tender.
