Double-Cheese Air Fryer Croutons
These double-cheese air fryer croutons are so easy to make and add crunch, savory flavor, and a little character to soups and salads. They’re also a great way to use up leftover or stale sourdough.
I developed them to top my Roasted Red Pepper Gouda Soup. I had some Gouda left over and thought they would be perfect combined with a bit of freshly grated Parmesan cheese. The double cheese gives the crouton so much more flavor …..and they’re great for snacking on too.

How To Make Double Cheese Air Fryer Croutons
Refer to the printable recipe card below for ingredient quantities and detailed instructions.



1. Remove the crusts and cut the sourdough into 1-inch cubes.
2. Toss the bread with olive oil and salt.
3. Arrange the cubes in a single layer and air-fry at 275°F for 10 minutes



4. Once the cubes are crisp, sprinkle with half of the Gouda-Parmesan blend.
5. Air-fry at 325°F for 5 minutes; gently turn the cubes, then sprinkle with the remaining cheese
6. Air-fry for 5 more minutes, until the cheese is melted and golden

Substitutions & Variations
- Leave the crusts on: For a more rustic look, leave the crusts on and measure 4 cups of cubes. The 147 g measurement comes from my crustless batch.
- Try another loaf: A sturdy white loaf or French bread is a good substitute if that is what you have.
- Change the seasoning: Try a little freshly ground black pepper, cayenne, or dried herbs with the salt.
- Cheese substitutions: Try cheddar, Monterey Jack, or Gruyère in place of the Gouda, keeping the Parmesan for its savory flavor.

Expert Tips
- For less cleanup: If your air fryer’s manufacturer permits it, add a parchment liner beneath the crisped bread before the cheese stage to catch melted cheese. Keep it secured beneath the food, and never preheat with loose parchment.
- Fresh or stale bread both work: The initial air-frying stage brings either to the same crisp texture before the cheese goes on. Air-fry at 275°F for about 10 minutes, checking that the cubes are crisp before moving to the cheese stage.
- Leave space between the bread cubes during the initial air-frying stage so air can circulate and crisp them evenly. Once crisp, move them closer together before sprinkling on the cheese. This keeps more cheese on the bread instead of letting it fall to the bottom of the basket
Recipe Testing Notes (What Worked Best)
- I first tried Parmesan on its own, but it didn’t stick to the bread cubes; most of it fell into the bottom of the basket. Adding Gouda gave the Parmesan a melted layer to cling to. The blend also gave me the stronger cheese flavor I was looking for.
- Keep the Gouda cold: Once the grated Gouda warmed up, it clumped and became harder to sprinkle evenly over the bread cubes. Grating it and keeping it chilled until needed made it easier to distribute.
Make Ahead and Storage
Make ahead: Grate the cheeses and store them in the refrigerator, covered. Cut the bread into cubes and store it in a cool, dry place for up to 2 days.
Storage: Store finished croutons in an airtight container and use within 5 days.

Air Fryer Croutons FAQs
Sourdough is my go-to, but French bread, Italian bread, or a sturdy sandwich loaf should work, too. Fresh or slightly stale bread both work well. Cut it into even, 1-inch cubes and check for crispness before adding the cheese. Smaller cubes or thinner slices will need less cooking time.
Try cheddar, Monterey Jack, or Gruyère in place of the Gouda, keeping the Parmesan for that extra punch of savory flavor. Choose a cheese that melts well and grate it finely. I tested this recipe with Gouda and Parmesan, so other combinations may melt and brown a little differently.
