Pat the chicken breasts dry with a paper towel. Season both sides generously with salt, garlic powder, oregano, black pepper, and chili powder.
Heat the olive oil in a large skillet over medium-high heat. Add the seasoned chicken breasts and cook undisturbed for 5-7 minutes until golden brown on one side.
Flip the chicken breasts using tongs and cook for another 5-7 minutes until the internal temperature reaches 165°F (75°C). Remove the chicken from the skillet and set aside.
Add 2 tablespoons of butter to the same skillet. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant, being careful not to burn it.
Add the broccoli florets and water or chicken stock to the skillet. Sprinkle Italian seasoning and crushed red pepper on top. Cover with a lid and steam for 3-4 minutes until tender and vibrant green.
Slice the cooked chicken into strips and return it to the skillet with broccoli. Add remaining butter and lemon juice, stirring to combine and coat everything in garlic butter sauce.
Serve hot, garnished with additional lemon juice if desired. Enjoy with rice, quinoa, or on its own for a low-carb meal.
