Upside-Down Sausage and Mushroom Pizza

The first time I had anything resembling this pizza was at a potluck during my college days. A friend’s roommate, a self-proclaimed “culinary artist” with a penchant for dramatic flair, brought a bubbling, fragrant dish that looked, well, a little chaotic. He called it “Deconstructed Pizza Surprise.” Despite the questionable name and unconventional appearance, one bite of the savory sausage, earthy mushrooms, and gooey cheese nestled under a golden crust, and I was hooked. It wasn’t just pizza; it was an experience, a comforting, hearty dish that defied expectations and brought everyone together. This recipe is my slightly less chaotic, but equally delicious, homage to that unforgettable potluck creation.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 6
• Yield: 1 pie
• Dietary Type: N/A

Ingredients

• 2 teaspoons olive oil
• 1 lb hot Italian turkey sausage, casing removed
• 1 cup onion, sliced
• 8 ounces mushrooms, sliced
• 1 cup pasta sauce
• 1 cup pizza sauce
• 1/2 cup black olives, sliced
• 16 ounces mozzarella cheese, shredded
• 2 eggs
• 1 cup milk
• 1 tablespoon olive oil
• 1 cup all-purpose flour
• 1/2 teaspoon salt
• 1/4 cup Parmesan cheese, grated

Equipment Needed

• Large skillet
• 13×9 inch baking dish
• Medium bowl
• Whisk
• Wooden spoon

Instructions

1. Begin by preheating your oven to 400 degrees F.
2. Heat 2 teaspoons of olive oil in a large skillet over medium heat.
3. Add 1 lb of hot Italian turkey sausage, with the casing removed, to the skillet. Cook for about 3 minutes, or until the sausage is browned and cooked through. Be sure to break up the meat into smaller pieces as it cooks using a wooden spoon. This ensures even cooking and prevents large clumps of sausage in your final pizza.
4. Add 1 cup of sliced onion and 8 ounces of sliced mushrooms to the skillet with the sausage. Continue to cook for approximately 2 minutes, or until the onions are softened and translucent, and the mushrooms have begun to release their moisture.
5. Pour in 1 cup of pasta sauce, 1 cup of pizza sauce, and ½ cup of sliced black olives. Bring the mixture to a gentle simmer, allowing it to bubble lightly for about 2 minutes. This step helps the flavors meld together beautifully.
6. Remove the skillet from the heat. Transfer the sauce mixture to the bottom of a 13×9-inch baking dish. Ensure that the sauce is spread evenly across the bottom of the dish.
7. Evenly distribute 16 ounces of shredded mozzarella cheese over the sauce layer in the baking dish. The cheese will create a delicious, gooey base for the crust.
8. In a medium bowl, whisk together 2 eggs, 1 cup of milk, and 1 tablespoon of olive oil until the mixture is well blended. This forms the base of the “crust” layer.
9. Whisk in 1 cup of all-purpose flour and ½ teaspoon of salt into the egg mixture until everything is thoroughly combined and smooth. Make sure there are no lumps remaining.
10. Gently pour the flour mixture over the cheese and sauce in the baking pan. Spread evenly to cover the entire surface.
11. Sprinkle the top of the dish with ¼ cup of grated Parmesan cheese. This will add a lovely golden-brown color and a nutty, savory flavor to the crust.
12. Bake in the preheated oven for 25 minutes, or until the top is golden brown and the batter is fully cooked. Use a toothpick to check for doneness; it should come out clean when inserted into the center.
13. Once baked, remove the dish from the oven and let it stand for 5 minutes before slicing and serving. This allows the pizza to set slightly, making it easier to cut and serve.

Expert Tips & Tricks

• Spice it up: If you want an extra kick, add a pinch of red pepper flakes to the sausage mixture while cooking.
• Sausage Swap: Feel free to experiment with different types of sausage. Sweet Italian sausage, chorizo, or even plant-based sausage alternatives work great.
• Vegetarian Version: Replace the sausage with sautéed bell peppers, zucchini, and eggplant for a delicious vegetarian option.
• Make-Ahead Magic: You can prepare the sausage and mushroom mixture a day in advance. Store it in the refrigerator and simply assemble the pizza when you’re ready to bake.
• Prevent Soggy Bottom: If you find the bottom is getting soggy, try placing a baking sheet on the rack below to help deflect some of the heat.

Serving & Storage Suggestions

Serve this upside-down pizza hot, straight from the oven. Garnish with fresh basil or a sprinkle of Parmesan cheese for an extra touch. It’s a crowd-pleaser that’s perfect for weeknight dinners, casual gatherings, or potlucks.

For leftovers, allow the pizza to cool completely before storing it in an airtight container in the refrigerator. It will keep for up to 3 days.

To reheat, you can microwave individual slices for a quick and easy meal. For a crispier crust, reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes. Freezing is not recommended as the texture of the crust and cheese can change.
