Equipment

  • Cast iron skillet
  • Tongs
  • Knife
  • cutting board
  • Wooden Spoon or Spatula
  • Meat thermometer Optional

Ingredients

  • 6 chicken thighs bone-in or boneless
  • 2 tablespoons oil olive or avocado
  • 1 teaspoon salt
  • ½ teaspoon pepper optional
  • 1 teaspoon lemon pepper
  • 1 teaspoon Italian seasoning
  • 2 tablespoons butter
  • 2 cups trimmed green beans
  • 1 cup sliced sweet mini peppers any color

Instructions

  • Heat oil in cast iron skillet over medium heat.
  • Season chicken thighs with salt, pepper, lemon pepper, and Italian seasoning.
  • Add chicken to skillet and sear 6–7 minutes per side, until cooked through.
  • Lower heat and add green beans, sweet peppers, and butter to the skillet.
  • Sauté everything together for 5–6 minutes, until veggies are tender-crisp.
  • Serve hot, straight from the pan.

Notes

  • Chicken Options: You can use boneless skinless thighs or bone-in with skin — both work great. Just adjust cooking time slightly depending on thickness.
  • Vegetable Swaps: Swap green beans for asparagus, broccoli, or even zucchini. Add veggies during the last 5–7 minutes so they don’t overcook.
  • Butter Boost: The butter added at the end adds richness and helps the veggies sauté beautifully — don’t skip it!
  • Cast Iron Tip: If your pan is newer or not well-seasoned, add a little extra oil before cooking to prevent sticking.
  • Want it spicy? Add a pinch of crushed red pepper flakes or a dash of hot sauce when you add the peppers.
