Ingredients
  

  • 2 to 2.5 pounds boneless, skinless chicken thighs or breasts
  • 1 pound fresh green beans, trimmed (or 12 ounces frozen, unthawed)
  • 6 tablespoons unsalted butter, cut into pieces
  • 6 cloves garlic, minced (or 2 teaspoons garlic powder in a pinch)
  • 1 small onion, finely chopped (optional but recommended)
  • 1/2 cup low-sodium chicken broth
  • 1 tablespoon fresh lemon juice (plus extra wedges for serving)
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon black pepper
  • 1 teaspoon dried Italian seasoning or a mix of dried thyme and oregano
  • 1/2 teaspoon paprika (smoked or sweet)
  • 1/4 teaspoon red pepper flakes (optional, for heat)
  • 2 tablespoons chopped fresh parsley or chives, for garnish

Method
 

  1. Prep the chicken: Pat the chicken dry with paper towels. Season both sides with salt, pepper, paprika, and Italian seasoning. This simple rub helps lock in flavor.
  2. Optional sear for extra flavor: If you have 5 minutes, brown the chicken in a skillet with a little oil for 1–2 minutes per side. It’s not required, but it adds a nice golden edge and richer taste.
  3. Build the base: Add chopped onion, minced garlic, and butter pieces to the slow cooker. Pour in the chicken broth and lemon juice. Stir lightly to spread the aromatics and butter around.
  4. Nestle in the chicken: Place the seasoned chicken in a single layer if possible. Spoon some of the buttery mixture over the top.
  5. Cook low and slow: Cover and cook on Low for 3.5 to 4.5 hours (thighs) or Low for 3 to 4 hours (breasts), until the chicken reaches 165°F and is tender but not falling apart.
  6. Add the green beans: About 45–60 minutes before the chicken is done, scatter the green beans on top. Gently toss them with the sauce so they cook evenly. If using frozen beans, add them 60–75 minutes before the end.
  7. Taste and adjust: When done, taste the sauce. Add a pinch of salt, a squeeze of lemon, or a few red pepper flakes if you want more zing.
  8. Serve and garnish: Transfer the chicken and green beans to plates. Spoon over the garlicky butter sauce. Finish with fresh parsley or chives. Serve with rice, mashed potatoes, or crusty bread to soak up the juices.
