For the Filling
• Mozzarella Cubes – Essential for that gooey, melty core; low-moisture mozzarella is recommended for the best results.
• Pepperoni/Sausage (Optional) – Adds classic pizza flavor; use mini varieties for a fun twist.

Step‑by‑Step Instructions for Sourdough Pizza Bombs
Step 1: Mix the Dough
In a large mixing bowl, combine your sourdough discard, all-purpose flour, baking powder, olive oil, and a dash of salt. Stir with a wooden spoon until a shaggy dough begins to form, ensuring all ingredients are well incorporated. This initial mixing typically takes about 1-2 minutes, resulting in a dough that’s slightly sticky but manageable.
Step 2: Rest the Dough
Cover the bowl with a damp kitchen towel or plastic wrap and allow the dough to rest for 10 minutes. This resting period is vital as it relaxes the gluten, making the dough easier to shape later. During this time, prepare your filling options and preheat the oven to 375°F (190°C) for baking.
Step 3: Shape the Dough
After resting, sprinkle a clean surface with flour and turn the dough out onto it. Divide it into 12 equal pieces and roll each piece into a ball. Flatten each ball gently to form discs approximately 3 inches in diameter. You’ll see the dough should be smooth and pliable, making it ready for filling.
Step 4: Fill the Bombs
Take one disc and place a cube of mozzarella, along with your chosen fillings, in the center. Carefully pinch the edges together, sealing it tightly to form a ball. Repeat this process with the remaining discs, ensuring not to overfill them—aim for a snug fit to avoid any leaks during baking.
Step 5: Bake the Pizza Bombs
Arrange your filled Sourdough Pizza Bombs on a lined baking sheet, spacing them evenly. Place in the preheated oven and bake for 18-20 minutes, or until they are golden brown. For an extra crispy texture, spritz the tops lightly with water halfway through the baking time, creating a delightful crunch.
Step 6: Cool and Serve
Once baked, remove the Sourdough Pizza Bombs from the oven and let them cool on the baking sheet for about 5 minutes. This cooling allows the molten cheese to settle slightly and makes them easier to handle. Serve warm with a side of marinara sauce or your favorite dipping sauce for a delightful snack experience.

How to Store and Freeze Sourdough Pizza Bombs
Room Temperature: Store leftover Sourdough Pizza Bombs in an airtight container for up to 2 days, keeping them fresh and ready for snacking.
Fridge: If you prefer, keep the bombs in the refrigerator for up to 4 days in a sealed container. Reheat in the oven or microwave before serving.
Freezer: Freeze unbaked, filled Sourdough Pizza Bombs on a tray, then transfer to a freezer bag for up to 3 months. Bake from frozen with an additional 5 minutes of cooking time.
Reheating: For best results, reheat the baked bombs in a 350°F oven for about 10 minutes to restore their crispiness, making them just as delightful as the first bite!
Make Ahead Options
These Sourdough Pizza Bombs are a time-saver for busy home cooks! You can prepare the filling and form the bombs up to 24 hours in advance. Just fill and seal the bombs as instructed, then place them on a baking sheet and cover tightly with plastic wrap. Refrigerate until you’re ready to bake. For even longer storage, you can freeze the filled but unbaked bombs for up to 3 months. When ready to enjoy, bake them straight from the freezer, adding 5 extra minutes to the baking time. This way, you’ll have delicious, cheesy snacks that are just as delightful as when freshly made, making your family gatherings or late-night snacks effortless!
Expert Tips for Sourdough Pizza Bombs
-
Don’t Overstuff: Ensure you don’t put too much filling inside each bomb; overstuffing can lead to leaks while baking and make a mess.

Cheese Choice: Use low-moisture mozzarella for that gooey, melty center. If you want a richer flavor, you could mix in cream cheese with your fillings.
-
Chilling Trick: If you’re having trouble shaping the bombs, refrigerate them for about 15 minutes before baking; this firms them up and helps maintain their shape.

Sourdough Pizza Bombs Recipe FAQs
What is the best way to select ripe sourdough discard?
Absolutely! When choosing sourdough discard, look for a bubbly texture and a pleasantly tangy smell. If the discard has dark spots or an off-putting odor, it’s best to discard it. Fresh discard gives your Pizza Bombs that unique sour flavor we love.
How should I store leftover Sourdough Pizza Bombs?
Store any leftover Sourdough Pizza Bombs in an airtight container at room temperature for up to 2 days for the best texture. If you have more time, refrigerate them for up to 4 days. Just remember to reheat them in the oven or microwave before enjoying!
Can I freeze Sourdough Pizza Bombs?
Absolutely! For convenience, freeze unbaked, filled Pizza Bombs on a tray first, then transfer them to a freezer bag. They will keep well for up to 3 months. When you’re ready to bake, cook them directly from frozen, adding an additional 5 minutes to the baking time for a fresh and delicious snack.
What should I do if my dough is too sticky?
No worries! If you find the dough too sticky to handle, simply sprinkle a little more flour on your work surface and your hands as you shape the bombs. Remember, though, that a little stickiness is normal with sourdough, so aim for a balance between stickiness and manageability.
Are there any dietary considerations for Sourdough Pizza Bombs?
Very much so! To make these pizza bombs suitable for a vegan diet, swap the mozzarella for plant-based cheese and include seasonal veggies. If allergies are a concern, always double-check ingredient labels, particularly for fillers in store-bought products like pepperoni or sausages.
How do I avoid leaking during baking?
Great question! To prevent leaking, ensure you accurately gauge your filling amount; don’t overstuff them! Pinching the edges securely is essential—this creates a seal that keeps all the cheesy goodness inside during baking. Aim for a snug fit without too much excess filling, and you’ll be golden!
