Preheat your oven to 400°F (200°C) and make sure your oven rack is positioned in the center for even browning. If you're using an air fryer instead, set it to 375°F (190°C).

Lightly grease an oven-safe bowl or ramekin with a small amount of olive oil or cooking spray. This prevents sticking and makes the cheese easier to scoop out later.

Spread 1–2 tablespoons of marinara sauce on the bottom of the bowl to create a flavorful base layer and keep the chicken from drying out as it bakes.

Add half of your diced or shredded chicken into the bowl, spreading it out evenly so every bite has protein.

Sprinkle a small handful of shredded mozzarella over the chicken. This helps the layers bind together as the cheese melts.

Add your veggies of choice (such as chopped bell peppers, mushrooms, onions, olives, or jalapeños). If using watery vegetables, pat them dry first or lightly sauté them to remove moisture.

Add the remaining chicken on top of the veggies, spreading it out so the bowl fills evenly from edge to edge.

Spoon over the remaining marinara sauce, making sure it coats the chicken well. This keeps the bowl juicy and prevents dry spots.

Sprinkle your seasonings evenly: Italian seasoning, garlic powder, salt, pepper, and red pepper flakes if you enjoy heat. Rub a little of the seasoning into the top to help it stick.

Add a final, generous layer of mozzarella cheese, followed by grated parmesan for a golden, bubbly finish.

Drizzle 1 teaspoon of olive oil over the top. This helps the cheese brown beautifully and adds richness to the dish.

Place the bowl in the preheated oven and bake for 10–12 minutes, or until the cheese is melted, bubbling around the edges, and starting to turn lightly golden on top.

Remove carefully (the bowl will be very hot) and let it rest for 2 minutes. This allows the layers to settle and makes the texture thicker and easier to eat.

Serve warm and enjoy your cheesy, high-protein crustless pizza bowl straight from the oven-safe dish.
