Steps
Before you start
- Have your sourdough discard at room temperature (preferably, but cold works)
- Preheat air fryer to 375°F (190°C)
- Prep tomatoes, basil, and burrata before cooking so assembly is quick
Mix dough
- In a large mixing bowl, combine 1 cup (240 ml) sourdough discard, 0.75 cup (90 g) all-purpose flour, 2 tablespoons (30 ml) olive oil, 0.5 teaspoon (3 g) kosher salt, and garlic powder if using.
- Stir with a wooden spoon or rubber spatula until a shaggy dough forms.
- The mixture will be sticky and wet—this is correct.
- Let it rest for 2 minutes so the flour fully hydrates.

Ready when: Sticky, cohesive dough with no dry flour visible
Tip: Don't overmix; slight lumps are fine. The dough will be looser than bread dough.
Shape roundsOven 375°F / 190°C
- Preheat air fryer to 375°F (190°C) if not already done.
- Lightly flour a work surface.
- Divide dough into 8 equal pieces (about 2.5 tablespoons or 40 grams each).
- Working quickly, gently shape each piece into a ball, then pat or flatten it into a 2.5-inch (6.5 cm) round about 0.25 inch (6 mm) thick.
- If the dough springs back, let it rest 30 seconds before reshaping.
- Rounds don't need to be perfectly even.

Ready when: 8 flat rounds, each about 2.5 inches across and 0.25 inch thick
Tip: Keep your hands lightly floured to prevent sticking. If dough is too sticky to handle, chill it for 5 minutes.
Prepare tomatoes
- While shaping dough, halve 1 cup (150 g) cherry tomatoes lengthwise.
- Place in a small bowl and toss with a pinch of salt and red pepper flakes if using.
- Set aside.

Ready when: Tomatoes halved and lightly seasoned
Tip: Don't prep tomatoes too far ahead—halved tomatoes release liquid and can become watery.
Air fry roundsOven 375°F / 190°C
- Line the air fryer basket with parchment paper if desired (makes cleanup easier).
- Working in batches if needed, arrange the 8 dough rounds in a single layer in the air fryer basket, leaving about 0.5 inch (1.3 cm) between them.
- They will expand slightly.
- Air fry at 375°F (190°C) for 8–10 minutes, until the edges are golden brown and the tops begin to show light browning.
- Shake the basket gently at the 5-minute mark if you notice uneven browning.

Ready when: Edges are golden brown, tops are light golden, rounds are slightly puffed
Tip: Don't skip parchment paper—it prevents sticking and the delicate rounds may break when removed from a bare basket.
Roast tomatoesOven 375°F / 190°C
- While the dough rounds air fry, add the halved cherry tomatoes to the air fryer for the final 4–5 minutes of the dough's cooking time (place them on a separate rack or push gently to the side of the basket if you have space).
- They should cook alongside the rounds, softening slightly and releasing their juices.
- If your air fryer is small and the rounds take up all space, roast the tomatoes separately after removing the rounds: set air fryer to 375°F (190°C) for 5 minutes.

Ready when: Tomatoes are soft, skin is lightly charred on edges, and they release their juices
Tip: Roasting tomatoes in the air fryer concentrates their sweetness and creates a light char that balances the rich burrata.
Cool slightly
- Remove the rounds from the air fryer and place them on a cooling rack or clean plate.
- Let them cool for 1–2 minutes so they firm up slightly and become even crispier.
- They will continue to crisp as they cool.
- Don't skip this step—warm rounds are fragile.

Ready when: Rounds are firmer to the touch and sound crispy when tapped
Tip: Cooling also allows burrata to stay creamy when you add it—it won't melt into the hot bread.
Top and serve
- Working quickly while rounds are still warm but cool enough to handle, place a piece of cold burrata (about 1 ounce or 28 grams) on the center of each round, gently pressing down slightly.
- Spoon 2–3 pieces of roasted cherry tomato on top of or beside each burrata portion.
- Scatter torn fresh basil over all 8 rounds.
- Finish with a light pinch of fleur de sel or finishing salt and a few grains of red pepper flakes if desired.
- Serve immediately.

Ready when: All rounds are topped with cheese, tomato, and basil, ready to eat
Tip: Assemble just before serving so the crispy rounds don't soften from the moisture of the burrata and tomatoes.
Good to know
Tips
- Sourdough discard doesn't need to be fed or bubbly—cold, sluggish discard works great here and gives better tang. Use the discarded portion when you feed your starter.
- If your air fryer runs hot, start checking rounds at 7 minutes. They should be light golden, not dark brown, for the best crispy-but-tender texture.
- Make sure burrata is cold before assembling. Room-temperature or warm burrata will lose its creamy center and become rubbery.
- These rounds are best eaten within 30 minutes of assembly—the crispy base will gradually soften from the toppings, but they remain delicious for a few hours.
Make ahead
Sourdough rounds can be shaped, covered, and refrigerated up to 4 hours ahead. Air fry directly from the fridge, adding 1–2 minutes to cooking time. Cherry tomatoes can be halved up to 2 hours ahead and refrigerated. Assemble only just before serving.
Storage & reheating
Unfilled rounds keep in an airtight container at room temperature for 1 day and can be re-crisped in a 350°F (175°C) air fryer for 2–3 minutes before topping. Do not refrigerate filled rounds; they are best served immediately. Leftover filled rounds can be eaten at room temperature within a few hours but will soften.
Substitutions
- burrata cheese → fresh mozzarella di bufala or ricotta (about 2 tablespoons per round). Fresh mozzarella is firmer than burrata; ricotta is tangier and looser. Both work beautifully.
- cherry tomatoes → sliced ripe heirloom tomatoes or sun-dried tomatoes (reconstituted in warm water). Heirloom tomatoes will be juicier; sun-dried will be more intense and chewier.
- fresh basil leaves → fresh oregano, arugula, or a mix of both. Oregano is more herbaceous; arugula adds peppery bite. Both complement burrata and tomato.
- all-purpose flour → whole wheat or spelt flour (use same amount by volume). Whole grains will make slightly denser, nuttier rounds. Increase water by 1–2 tablespoons if dough is too dry.
