Ingredients
  

  • Chicken: 2 pounds boneless, skinless chicken thighs (or breasts if you prefer leaner meat)
  • Low-carb vegetables: 1 medium zucchini, 1 small yellow squash, 1 red bell pepper, 1 small red onion, 1 cup grape tomatoes
  • Olives (optional but great): 1/3 cup sliced black or Kalamata olives
  • Garlic: 3–4 cloves, minced
  • Olive oil: 3 tablespoons
  • Italian seasoning: 2 teaspoons (or a mix of dried oregano, basil, thyme)
  • Smoked paprika: 1 teaspoon (adds warmth and color)
  • Red pepper flakes: 1/2 teaspoon (adjust to taste)
  • Salt and pepper: 1–1.5 teaspoons kosher salt, 1/2 teaspoon black pepper
  • Tomato element: 1/3 cup no-sugar-added marinara or crushed tomatoes
  • Cheese: 1 cup shredded mozzarella, 1/4 cup grated Parmesan
  • Fresh basil or parsley: A handful, chopped, for garnish
  • Lemon: 1 lemon for zest and a squeeze of juice (optional but brightens the dish)

Method
 

  1. Preheat and prep. Heat your oven to 400°F (200°C). Lightly grease a large baking dish or sheet pan. Pat the chicken dry with paper towels for better browning.
  2. Chop the vegetables. Slice zucchini and squash into half-moons, bell pepper into strips, and onion into wedges. Leave grape tomatoes whole so they burst as they bake.
  3. Season everything. In a big bowl, toss chicken and vegetables with olive oil, garlic, Italian seasoning, smoked paprika, red pepper flakes, salt, and pepper. Add lemon zest if using for a fresh lift.
  4. Layer the pan. Spread vegetables evenly in the dish. Nestle the seasoned chicken on top. Spoon the no-sugar-added marinara in small dollops over the chicken and vegetables so it bakes into the juices.
  5. Add olives. Scatter sliced olives across the pan for briny, salty balance. If you don’t love olives, capers work too—use half as much.
  6. Bake uncovered. Roast for 20–25 minutes if using chicken breasts, or 25–30 minutes for thighs, until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender.
  7. Cheese time. Sprinkle mozzarella and Parmesan over the chicken and vegetables. Return to the oven for 5–7 minutes, until melted and lightly golden. For extra color, broil for 1–2 minutes, watching closely.
  8. Finish with freshness. Let it rest 5 minutes. Squeeze a little lemon juice over the top and scatter chopped basil or parsley. This little step wakes up the flavors.
  9. Portion for meal prep. Divide evenly into 4–5 airtight containers. Spoon pan juices over each portion to keep the chicken moist.
