Step 1: Prepare the Chicken: Pat the chicken breasts dry with paper towels. This helps them brown better. In a small bowl, combine the lemon juice, rosemary, thyme, minced garlic, and black pepper.
Step 2: Marinate the Chicken: Place the chicken breasts in a shallow dish and pour the lemon-herb mixture over them, coating evenly. Allow to marinate for at least 15 minutes, or up to 30 minutes in the refrigerator. The longer it marinates, the more flavorful it will be.
Step 3: Saut the Vegetables: Heat the olive oil in a large skillet or Dutch oven over medium heat. Add the sliced zucchini, yellow squash, and red bell pepper. Saut the vegetables for about 5-7 minutes, or until they are tender-crisp, stirring occasionally. Remove the vegetables from the skillet and set aside.
Step 4: Sear the Chicken: Add the marinated chicken breasts to the same skillet. Sear the chicken for 5-6 minutes per side, or until golden brown and cooked through. The internal temperature should reach 165F (74C).
Step 5: Combine and Simmer: Return the sauted vegetables to the skillet with the chicken. Pour in the low-sodium chicken broth. Bring to a simmer and cook for an additional 2-3 minutes, allowing the flavors to meld together. Ensure the chicken remains moist and the vegetables are heated through.
Step 6: Serve: Garnish with lemon slices (optional). Serve the low-sodium lemon-herb chicken and vegetables immediately. Consider pairing it with quinoa, brown rice, or a side salad.
Optional Tip: For a creamier sauce, add a tablespoon of plain Greek yogurt or a splash of unsweetened almond milk at the end of cooking. Substitute other vegetables according to preference or seasonal availability.
