Upside Down Pizza Ingredients

Upside Down Pizza raw ingredients that are labeled

You’ll need: 

For the Meat Mixture

  • 1½ pounds lean ground beef
  • ½ large yellow onion, diced finely 
  • 1 (24-ounce) jar traditional spaghetti sauce 
  • 1 (7-ounce) package pepperoni, chopped
  • 1 tablespoon minced garlic
  • 1 tablespoon Italian seasoning 
  • 1 teaspoon salt
  • ½ teaspoon black pepper

For the Cheese Layer

  • 1½ cups of shredded mozzarella cheese

For the Popover Top

  • 3 large eggs, room temperature 
  • 1½ cups whole milk, room temperature
  • 2 tablespoons olive oil
  • 1½ cups all-purpose flour, sifted 
  • ¾ teaspoon salt 
  • ⅓ cup shredded parmesan cheese

SUBSTITUTIONS AND ADDITIONS

CRESCENT ROLLS OR BISCUITS: If you’d like to skip the traditional popover top of this pizza, you can substitute a roll of Pillsbury Crescent Rolls or Biscuits. You’ll need to pre-bake them for half of the recommended time, and then flip them over and bake them for the remaining time on top of your pizza. This will ensure that they cook through and aren’t underdone on the bottom. 

VEGGIES OR OTHER “TOPPINGS”: While they won’t be actual toppings since they will be inside casserole, you could definitely add any of your favorite items that you usually would order on a pizza. Add green pepper, olives, hot peppers, and mushrooms to make it supreme.

How To Make This Upside Down Pizza Recipe

OUR RECIPE DEVELOPER SAYS

Take out your eggs and milk a few minutes before starting this recipe to bring them to room temperature. 

STEP ONE: Preheat the oven to 400°F. Spray a glass 9×13-inch baking dish with cooking spray. Set aside. 

PRO TIP:

For best results, use a glass rather than a ceramic baking dish for your pizza. 

STEP TWO: In a large skillet, brown beef over medium heat until no longer pink. Drain the grease and return the ground beef to the skillet. Use a meat masher to break the meat into small pieces. 

STEP THREE: Add onions and cook for 5 minutes, stirring often so that they do not burn. Add minced garlic and cook for an additional 2 minutes, stirring often. 

STEP FOUR: Add Italian seasoning, salt, black pepper, and pepperoni. Stir well and continue to cook for an additional 3 to 5 minutes, or until the pepperoni is cooked and heated through.

STEP FIVE: Add tomato sauce to the beef mixture and stir well. Let simmer for 3 minutes. 

STEP SIX: Add the meat mixture to the bottom of the pan and spread out evenly using a rubber spatula. Top with shredded mozzarella cheese.

STEP SEVEN: Place in the preheated oven while you combine the popover mixture so that the baking dish is very hot when you pour the popover mixture into it so that it bubbles up. 

PRO TIP:

It is very important that your baking dish is HOT before you add the popover top or this recipe will not work properly.

STEP EIGHT: In a separate medium mixing bowl combine sifted flour, eggs, milk, vegetable oil, and salt. Use a large spoon to mix together but make sure not to over mix.

PRO TIP:

This batter will be a bit runny and should be able to pour onto the top of the casserole.

STEP NINE: Remove the baking dish from the oven and pour the popover top mixture over the meat mixture, making sure to get the top all the way to the edges of the casserole dish. Sprinkle cup shredded parmesan cheese over the top of the bubble up top and place the pan back in the oven.

STEP TEN: Bake for 30 minutes, or until the top “crust” has puffed up and is a deep golden brown color. 

PRO TIP:

Do not open the oven while this is baking! Doing so could cause the top to not bubble up correctly or collapse.

How To Serve

Turn things upside down (literally!) on pizza night with something new. This cheesy dish is a great way for a different twist on traditional pizza. Add a simple Caesar salad on the side to complete your meal.

Storage

IN THE FRIDGE: If you have leftover upside-down pizza, it’s recommended to store it in your fridge for no longer than 2 to 3 days. Because of the popover top, the texture of the pizza will change quickly and may become soggy. 

IN THE FREEZER: We don’t recommend freezing this recipe as the popover top will become soggy during the thawing process.

FREQUENTLY ASKED QUESTIONS

Why did my popover top not bubble up?

There are a few reasons why your top might not have bubbled up. First, you need to make sure your milk and eggs are at room temperature. Second, you have to make sure your pan is HOT before adding the popover mixture. Third, you must not open the oven during baking or the top may fall.

Can I use different meat in this recipe?

Any ground meat or Italian sausage will work fine in this delicious recipe.

Can I add other toppings to the casserole?

Any of your favorite pizza toppings can be added to the casserole if you’d like.
