Prepare the Chicken: Start by slicing the chicken breasts into thin strips for even cooking. Season the chicken with salt, black pepper, and oregano.
Heat the Skillet: In a large skillet, heat the olive oil over medium-high heat. Once hot, add the chicken strips in a single layer, cooking for about 5-7 minutes until golden brown and cooked through. Stir occasionally to ensure even cooking.
Add Broccoli: Once the chicken is cooked, add the broccoli florets to the skillet. Stir and cook for an additional 3-4 minutes, until the broccoli is bright green and tender-crisp.
Build the Sauce: Add the minced garlic to the skillet and cook for about 30 seconds until fragrant. Pour in the chicken broth, lemon juice, lemon zest, and red pepper flakes (if using). Stir well to combine all ingredients.
Simmer: Bring everything to a gentle simmer, allowing the sauce to reduce for about 2-3 minutes. Ensure the chicken and broccoli are coated in the tasty lemon sauce.
Serve: Remove from heat and garnish with fresh chopped parsley. Serve warm over rice, quinoa, or enjoy it on its own!
