It’s simple enough for a weeknight and special enough for company. If you love pizza but want to stay on track with a low-carb lifestyle, this dish is the perfect solution.
Ingredients
Method
- Prep the oven and pan: Preheat the oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish with olive oil.
- Flatten the chicken: Place each chicken breast between two pieces of parchment and pound to an even 1/2–3/4-inch thickness. This helps it cook evenly and stay juicy.
- Season well: In a small bowl, mix garlic powder, onion powder, Italian seasoning, smoked paprika, salt, and pepper. Drizzle the chicken with olive oil and rub the seasoning mix all over both sides.
- Par-bake the chicken: Arrange the breasts in the baking dish, not overlapping. Bake for 12–15 minutes, until the centers are just starting to turn opaque. This step ensures the chicken isn’t overcooked later.
- Add the “pizza” layers: Remove the dish from the oven. Spoon marinara over each piece (about 1/4 cup per breast). Sprinkle evenly with mozzarella and Parmesan. Top with pepperoni, olives, and red onion if using.
- Finish baking: Return to the oven for 8–12 minutes, until the cheese is melted and bubbling and the chicken reaches an internal temperature of 165°F (74°C).
- Broil for color (optional): Switch to broil for 1–2 minutes to brown the cheese slightly. Watch closely to avoid burning.
- Rest and serve: Let the bake rest for 5 minutes. Garnish with chopped basil or parsley. Serve hot with a simple green salad or roasted veggies.

Storage Instructions
- Refrigerator: Cool completely, then store in an airtight container for up to 4 days.
- Freezer: Freeze portions tightly wrapped or in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating: Warm in a 325°F (165°C) oven for 12–15 minutes or microwave in 45-second bursts until hot.
Add a sprinkle of extra cheese before reheating to refresh the top.
Health Benefits
- Low in carbs: Skips the crust while delivering the pizza vibe, helping support ketosis or lower-carb goals.
- High in protein: Chicken and cheese keep you full longer and help maintain muscle mass.
- Balanced fats: Cheese and olive oil provide satisfying fats that support energy and satiety on keto.
- Customizable nutrients: Add fiber-rich, low-carb veggies like bell peppers, spinach, or mushrooms to boost vitamins and minerals without spiking carbs.
Common Mistakes to Avoid
- Using sugary sauce: Many jarred sauces contain added sugar. Choose one with 3–5 grams of carbs per 1/2 cup or make your own.
- Skipping the par-bake: If you add toppings to raw chicken, the cheese may burn before the meat cooks through.
- Overbaking: Dry chicken ruins the dish. Pull it as soon as it hits 165°F (74°C).
- Overcrowding the pan: Crowding traps steam and makes everything watery.
Use a large enough dish so pieces don’t overlap.
- Too many wet toppings: Watery veggies like mushrooms or spinach should be sautéed first to release moisture.
Variations You Can Try
- Meat Lover’s: Add cooked crumbled sausage and diced bacon with the pepperoni.
- Veggie Supreme: Sauté mushrooms, bell peppers, spinach, and onions, then layer under the cheese.
- BBQ “Pizza” Twist: Swap marinara for a low-sugar BBQ sauce and top with red onion and jalapeños. Use smoked gouda with mozzarella.
- Margherita Style: Use crushed tomatoes, fresh mozzarella slices, and plenty of fresh basil.
- Buffalo Ranch: Mix a little buffalo sauce with ranch (both low-sugar), top with mozzarella, and finish with green onions.
- Pesto Base: Use a basil pesto instead of marinara for a rich, herby version. Check the carb count on your pesto.
FAQ
Can I use chicken thighs instead of breasts?
Yes.
Boneless, skinless thighs work well and stay very juicy. Adjust baking time slightly, as thighs can cook a bit faster once flattened.
What’s the best keto-friendly marinara?
Look for a brand with no added sugar and simple ingredients like tomatoes, olive oil, garlic, and herbs. Aim for 3–5 grams of net carbs per 1/2 cup.
If in doubt, make a quick sauce by simmering crushed tomatoes with olive oil, garlic, salt, and oregano.
How do I prevent watery sauce?
Use a thicker marinara and avoid excess liquid from toppings. Sauté high-moisture veggies first, and don’t cover the dish while baking so steam can escape.
Can I make this ahead?
You can season and par-bake the chicken earlier in the day. Assemble with sauce and toppings just before the final bake for the best texture.
Fully baked leftovers also reheat well.
Is this recipe gluten-free?
Yes, as long as your marinara, pepperoni, and seasonings are certified gluten-free. Always check labels.
What sides go well with this?
Try a simple arugula salad with lemon and olive oil, roasted broccoli, or garlicky green beans. Cauliflower mash also pairs nicely.
Can I cook it in the air fryer?
Yes.
Air fry the seasoned chicken at 375°F (190°C) for 10–12 minutes, add sauce and toppings, then air fry another 3–5 minutes until the cheese is melted and the chicken is 165°F (74°C).
How do I scale this for a crowd?
Double the ingredients and use two baking dishes so the chicken isn’t crowded. Rotate the pans halfway through baking for even cooking.
