How to Make Vegetarian Pizza Casserole with White Beans and Rice Recipe
Step 1: Prepare Your Oven and Baking Dish
Preheat your oven to 375°F and lightly grease a 9 x 13 inch baking dish. This ensures everything cooks evenly and your casserole doesn’t stick when it’s time to serve.
Step 2: Mix the Base Ingredients
In a large mixing bowl, combine the cooked white rice, rinsed white beans, marinara or pizza sauce, diced bell peppers, diced onion, sliced mushrooms, garlic powder, dried oregano, dried basil, red pepper flakes if using, salt, and black pepper. Stir everything together gently but thoroughly until all ingredients are evenly distributed. This is where the magic begins as all the flavors start to meld.
Step 3: Assemble the Casserole
Spread the mixture evenly into the prepared baking dish. A smooth and even layer helps the casserole cook uniformly and looks inviting once baked.
Step 4: Add the Cheesy Toppings
Top the mixture with shredded mozzarella and parmesan cheese, spreading them evenly to create a luscious cheese blanket. Add the sliced black olives if you want that little extra savory burst.
Step 5: Bake Until Bubbly and Golden
Bake the casserole uncovered for 25 to 30 minutes, or until it is hot and bubbly and the cheese is melted with a lightly golden crust. The bubbling sauce and melted cheese are the ultimate signals of a perfect bake.
Step 6: Let It Rest
Allow the casserole to rest for about 5 minutes after baking. This step is crucial to let the flavors settle and the dish firm up slightly, making it easier to serve.

Garnishes
Fresh garnishes like chopped basil, a sprinkle of red pepper flakes, or a drizzle of quality olive oil can elevate the casserole’s flavor and add a beautiful finishing touch. The bright green basil offers a fresh contrast to the rich cheese and sauce.
Side Dishes
This casserole pairs wonderfully with simple sides like a crisp green salad dressed lightly with lemon vinaigrette or steamed vegetables that add crunch and freshness to complement the cheesy, hearty main event.
Creative Ways to Present
For a fun twist, serve the casserole family-style in the baking dish or scoop individual portions into mini ramekins for single servings. You can also top each portion with a swirl of pesto or a sprinkle of toasted pine nuts for an extra gourmet flair.

Storing Leftovers
After the casserole has cooled completely, store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors deepen over time, making for tasty meals later in the week.
Freezing
This Vegetarian Pizza Casserole with White Beans and Rice Recipe freezes beautifully. Portion into freezer-safe containers and freeze for up to 3 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
