How to Make Vegetarian Pizza Casserole with White Beans and Rice

Step 1: Sauté Aromatics

Preheat your oven to 375°F (190°C). In a skillet, heat olive oil over medium heat. Add diced onion and sauté until soft, about 3–4 minutes. Stir in minced garlic and cook for another minute.

Step 2: Mix the Casserole Base

In a large bowl, combine cooked rice, white beans, sautéed onion and garlic, marinara sauce, Italian herbs, salt, and pepper. Stir in half of the mozzarella cheese and all the Parmesan.

Step 3: Assemble the Casserole

Lightly grease an 8×8-inch or similar-sized casserole dish. Spread the rice and bean mixture evenly into the dish.

Step 4: Add Toppings

Layer your favorite pizza-style toppings—mushrooms, bell peppers, spinach, olives—over the rice mixture. Sprinkle the remaining mozzarella over the top.

Step 5: Bake Until Bubbly

Bake uncovered for 20–25 minutes, or until the cheese is melted and the casserole is hot and bubbly.

Step 6: Cool Slightly and Serve

Let the casserole rest for 5 minutes before serving. Slice and enjoy warm!

Flavor and Texture Tips

Use full-fat mozzarella for that classic pizza melt and stretch.
Add a pinch of red pepper flakes for heat.
Layer veggies strategically: soft ones (like mushrooms) on bottom, firmer ones (like peppers) on top.
Use short-grain rice if you want a slightly creamier texture.
