Ingredients
Instructions
1. Prepare Your Baking Surface: Preheat your oven to 400 F (200 C). Lightly grease a large baking sheet (approximately 13×18 inches) or line it with parchment paper for easy cleanup.
2. Roll Out the Dough: On a lightly floured surface, gently roll out your thawed sourdough pizza dough into a large rectangle, roughly 12×16 inches. The dough should be about 1/4 inch thick. If the dough springs back, let it rest for 5 minutes, then continue rolling.
3. Transfer and Score: Carefully transfer the rolled dough to your prepared baking sheet. Using a pizza cutter or a sharp knife, lightly score the dough into 12 equal squares. Do not cut all the way through, just score the surface to create guides for individual portions.
4. Add the Sauce and Cheese: Spread the pizza sauce evenly over the entire surface of the dough, leaving a small border around the edges. Sprinkle the shredded mozzarella cheese over the sauce, followed by the grated Parmesan cheese.
5. Distribute Toppings: If using, scatter your desired optional toppings evenly over the cheese. Don’t overload the squares, as this can make them soggy.
6. Season and Bake: Sprinkle the dried oregano over the toppings. Place the baking sheet in the preheated oven and bake for 18-22 minutes, or until the crust is golden brown and the cheese is bubbly and lightly browned.
7. Cool and Cut: Once baked, remove the pizza squares from the oven. Let them cool on the baking sheet for 5 minutes before using your scores as a guide to cut completely through the dough to separate the individual squares.
8. Serve or Freeze: Serve warm, or allow to cool completely before packaging for meal prep or freezing.

Everything You Need To Make This Recipe Without Stress
INGREDIENTS:

- 1 pound frozen sourdough pizza dough, thawed overnight in the refrigerator
- 1/2 cup pizza sauce
- 1 1/2 cups shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 1/2 teaspoon dried oregano
- Optional toppings: mini pepperoni, cooked sausage crumbles, diced bell peppers, sliced mushrooms, black olives
For the frozen sourdough pizza dough, you can use homemade sourdough discard pizza dough that you’ve previously frozen, or a store-bought frozen sourdough pizza dough if available. If using homemade, ensure it’s fully thawed before starting. For the pizza sauce, any brand you enjoy will work well; look for a low-sugar option if preferred. Feel free to use a blend of cheeses if you like, such as provolone or a pizza blend, in addition to or instead of mozzarella. The oregano adds a classic pizza flavor, but you can also use Italian seasoning.

Easy Variations And Serving Ideas That Fit Real Life
These pizza squares are incredibly versatile. For a kid-friendly twist, stick to classic pepperoni and extra cheese. You can also make “white pizza” squares by swapping the tomato sauce for a garlic and olive oil base, topped with mozzarella, ricotta, and a sprinkle of fresh parsley. For a heartier meal, add cooked ground beef or crumbled Italian sausage. Vegetarians can load up on finely diced bell peppers, onions, spinach, or roasted vegetables.
Serve these squares warm with a side of marinara sauce for dipping – kids especially love this! They’re also excellent alongside a fresh green salad for a balanced lunch or dinner. For a party or buffet, arrange them on a platter with various dipping sauces like ranch or a balsamic glaze. You can even make mini versions by cutting the dough into smaller squares before baking, perfect for appetizers.
Common Slip-Ups And How To Avoid Them
One common mistake is trying to roll out cold dough. If your sourdough pizza dough isn’t fully thawed and at room temperature, it will be difficult to roll and will spring back constantly. Plan ahead and let it thaw overnight in the refrigerator, then bring it to room temperature for about 30 minutes before working with it. Another pitfall is overloading the squares with too many toppings, which can lead to a soggy crust. Stick to a moderate amount of toppings to ensure even baking and a crispy base. Also, make sure your oven is fully preheated to the correct temperature. An underheated oven can result in a pale, chewy crust instead of a golden, crisp one. Finally, don’t skip the scoring step; it makes separating the individual squares much easier after baking.
How To Store It And Make It Ahead Without Ruining Texture
These sourdough lunchbox pizza squares are perfect for making ahead. Once baked and completely cooled, you can store them in an airtight container in the refrigerator for up to 3-4 days.
For longer storage and true meal prep convenience, these squares freeze beautifully. Arrange the cooled squares in a single layer on a baking sheet and freeze for about 1-2 hours until solid. This prevents them from sticking together. Once frozen solid, transfer them to freezer-safe bags or containers. They will keep well in the freezer for up to 2-3 months.
To reheat from the refrigerator, simply microwave for 30-60 seconds, or warm in a toaster oven at 350°F (175°C) for 5-7 minutes until heated through and crispy. From frozen, you can reheat them directly in a toaster oven or conventional oven at 375°F (190°C) for 10-15 minutes, or until hot and the cheese is bubbly. Microwaving from frozen is possible, but the crust won’t be as crisp.
Questions People Always Ask Before Making This Recipe
Can I use fresh sourdough pizza dough instead of frozen? Yes, absolutely! If you have fresh sourdough pizza dough, simply proceed with the recipe as written. Just ensure it’s at room temperature and ready to be rolled out.
What if I don’t have sourdough pizza dough? While this recipe highlights sourdough, you can substitute it with any store-bought fresh or frozen pizza dough. The cooking times might vary slightly, so keep an eye on it.
Can I make these gluten-free? If you use a gluten-free sourdough pizza dough, then yes, this recipe can be made gluten-free. Ensure all other ingredients are also certified gluten-free.
How do I prevent the crust from getting soggy? Avoid overloading with toppings, especially watery vegetables. You can also pre-bake the crust for 5-7 minutes before adding sauce and toppings if you’re concerned about a soggy bottom.
Can I prepare these and freeze them unbaked? It’s generally recommended to bake them first, then freeze. Freezing unbaked dough with toppings can lead to a less desirable texture and potentially soggy results when baked from frozen.
What are some good dipping sauces for these squares? Classic marinara, ranch dressing, garlic butter, or even a pesto aioli are all delicious options for dipping.
How do I get the cheese to be perfectly melted and bubbly? Ensure your oven is fully preheated. For extra browning, you can switch to the broiler for the last minute or two, but watch it very carefully to prevent burning.
Can I use different types of cheese? Absolutely! A blend of mozzarella and provolone is excellent, or you can add a sprinkle of cheddar for a sharper flavor.
