Ingredients

2 large boneless, skinless chicken breasts
1 pound fresh green beans, trimmed
1 packet (1 oz) garlic herb seasoning mix (or Italian dressing seasoning)
½ cup unsalted butter, melted

Optional Garnishes

Fresh chopped parsley
Freshly cracked black pepper
Grated Parmesan cheese
Lemon wedges for serving

Instructions

Lightly coat the inside of your slow cooker with nonstick cooking spray or a small amount of oil.
Arrange the trimmed green beans evenly across the bottom of the slow cooker.
Place the chicken breasts directly on top of the green beans.
Sprinkle the garlic herb seasoning mix evenly over both the chicken and the beans.
Pour the melted butter over everything, making sure the chicken is well coated.
Cover with the lid and cook on LOW for 5–6 hours or HIGH for 2½–3½ hours, depending on the thickness of the chicken.
Check that the chicken has reached an internal temperature of 165°F (74°C) using a meat thermometer.
If desired, remove the chicken and let it rest for 5 minutes before serving.
Stir the green beans gently to coat them in the flavorful butter and cooking juices.
Plate the green beans first, then place the chicken breast on top. Spoon extra garlic butter sauce over everything and garnish with parsley, black pepper, or Parmesan if desired.

Tips, Notes & Q&A

Can I use frozen green beans?
Yes. Frozen green beans work well, although they may release a little extra liquid. Reduce the cooking time slightly if using frozen vegetables.
Can I use chicken thighs instead?
Absolutely. Boneless or bone-in chicken thighs stay extra juicy and are a great substitute.
How can I add more flavor?
Add a few minced garlic cloves, sliced onions, mushrooms, or a splash of chicken broth for even richer flavor.
Can I make this dairy-free?
Yes. Replace the butter with olive oil or a dairy-free butter alternative.
How do I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or on the stovetop with a splash of broth or water to keep the chicken moist.
Can I freeze it?
Yes. Cool completely before transferring to freezer-safe containers. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
