UPSIDE DOWN PIZZA INGREDIENTS

A tray of food, with Pizza and Popover

You will need: 

Meat mixture: 

  • 1.5 lb lean ground beef
  • 1⁄2 large yellow onion, diced finely 
  • 1 (24 oz) jar traditional spaghetti sauce 
  • 1 (7 oz) package pepperoni
  • 1 tbsp minced garlic
  • 1 tbsp Italian Seasonings 
  • 1 tsp salt
  • 1⁄2 tsp black pepper

Cheese layer: 

  • 1.5 cups of shredded mozzarella cheese 

Popover top: 

  • 3 large eggs 
  • 1 1⁄2 cups whole milk
  • 2 tbsp olive oil
  • 1.5 cups all-purpose flour 
  • 3⁄4 tsp salt 
  • 1⁄3 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 you usually would order on a pizza. Add green peppers, olives, and mushrooms to make it supreme, or anything else to the mix!

HOW TO MAKE THIS UPSIDE DOWN PIZZA RECIPE

STEP 1: Preheat the oven to 400 degrees. Spray a glass 9×13” baking dish with cooking spray. Set aside. 

STEP 2: In a large skillet cook the ground 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 3: 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 4: Add Italian seasoning, salt, black pepper, and pepperoni. Stir well and continue to cook for an additional 3-5 minutes, or until the pepperoni is cooked and heated through. 

STEP 5: Add spaghetti sauce to the meat mixture and stir well. Let simmer for 3 minutes.

STEP 6: Add the meat mixture to the bottom of the baking dish and spread out evenly using a rubber spatula. Top with shredded mozzarella cheese. 

STEP 7: Place in the oven at 400 degrees while you combine the popover mixture. You want your baking dish to be very hot when you pour the bubble up mixture into it.

STEP 8: In a separate medium mixing bowl combine sifted flour, eggs, milk, vegetable oil, and salt. Use a large spoon to mix together. Don’t over mix. (NOTE: This batter will be a bit runny and should be able to pour onto the top of the casserole) 

STEP 9: 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 1⁄3 cup shredded parmesan cheese over the top of the bubble up top and place the pan back in the oven.

STEP 10: Cook at 400 degrees 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. 

STEP 11: Remove from the oven and serve immediately. 

Tips for making upside down pizza: 

  • Use a glass baking dish: For best results, use a glass (rather than ceramic) 9 x 13” baking dish for your pizza. 
  • Make sure your dish is hot before you pour in the popover top: Your baking dish will bake at 400 degrees for several minutes before adding your popover mixture. Be careful not to skip this step – your dish needs to be hot so that your top bubbles up! 
  • Don’t open the oven while the popover top is baking: Keep your oven closed the entire time your popover top is baking. Doing so could cause it to collapse! 
  • Keep your eggs and milk room temperature: Take out your eggs and milk a few minutes before starting this recipe to bring them to room temperature. 

STORAGE

AT ROOM TEMPERATURE 

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

Notes

Tip: Resist the urge to open the oven door while this is cooking, as doing so will prevent the top from rising. Make sure popover top is puffed and golden brown before opening oven door.
