Pizza night and breakfast don't usually have much in common, but this recipe might change your mind. The first time I made it, I discovered something surprising-the magic doesn't happen right away. After a night in the refrigerator, the eggs soak in, the flavors mingle, and the whole Leftover Pizza Casserole bakes up into something far greater than the sum of its parts.
If you're looking for an easy make-ahead breakfast for a weekend, holiday morning, or house full of guests, keep reading. This one has a way of disappearing fast, and nobody will believe it started with a few leftover slices from the night before!

What makes this recipe irresistible
This is what happens when pizza meets breakfast and decides to stay. The crust soaks up the eggs, the cheese gets melty and golden, and every bite has those little pockets of flavor from whatever toppings you started with. It feels hearty without being heavy-and it's a great way to clean out the fridge without anyone catching on.

Leftover Pizza Casserole
Equipment
- 1 9x13 casserole dish
Ingredients
- 4-5 slices leftover pizza cut into bite-sized pieces
- 8 large eggs
- 1 cup milk
- ½ cup heavy cream
- 1 ½ cups shredded cheese mozzarella, cheddar, or a mix
- ½ teaspoon garlic powder
- ½ teaspoon Italian seasoning
- ½ teaspoon salt
- ¼ teaspoon pepper
Instructions
- Spray a 9x13 baking dish with non-stick cooking spray.
- Chop the pizza slices into small ½ pieces. Spread the chopped pizza pieces evenly in the baking dish.

- In a large bowl, whisk together eggs, milk, cream (if using), garlic powder, Italian seasoning, salt, and pepper.

- Pour the egg mixture over the pizza. Sprinkle shredded cheese evenly on top.

- Cover it with plastic wrap and refrigerate. Let it soak overnight or at least 6 hours.
- Remove the casserole dish from the refrigerator and allow to sit on the counter for 30 minutes prior to baking.
- Preheat the oven to 375°F. Bake uncovered for 35-40 minutes, until the center is set and the top is golden.
- Let it rest 5-10 minutes before slicing so it holds together nicely. Enjoy!

Frequently asked questions (FAQ's)
Yes. The casserole needs to chill in the refrigerator for at least 4 hours so the egg mixture can soak into the pizza crust. For the best texture, assemble it the night before and let it rest overnight. The extra time helps everything bake up tender, flavorful, and evenly set.
Yes. Cooked bacon, breakfast sausage, diced bell peppers, onions, mushrooms, or spinach are all great additions. Just avoid adding ingredients with a lot of moisture unless they've been cooked first.
The center should be set and no longer jiggly when the dish is gently shaken. A knife inserted in the center should come out clean.

Deb's top tips
If your leftover pizza is loaded with toppings, increase the eggs from 8 to 10 to make sure everything is well coated and the casserole bakes up evenly. Before sliding the dish into the oven, sprinkle a little Parmesan cheese over the top. It adds a rich, savory flavor and helps create that golden, pizza-parlor finish everyone loves.
