Air-fried croissant croutons are a quick, rich, flaky alternative to bread croutons—especially handy for day-old croissants. Cut them into roughly 1/2-inch cubes and start at 350°F for 5–7 minutes, flipping halfway. Air fryers and recipes vary, so check early and remove pieces once they reach your preferred browning. “Best” is a matter of taste: published recipes show the idea works, but there is no controlled comparison proving croissant croutons are objectively superior.
How to make croissant croutons in an air fryer
- Cut the croissants: Slice them into roughly 1/2-inch cubes. Day-old croissants are a useful choice because the recipe from Beyond the Noms recommends them, though that is not evidence that fresh croissants will not work.
- Season to taste: For a savory version, toss the cubes with dried rosemary, garlic powder, grated Parmesan, salt, and black pepper. Seasonings are optional; use less salt if your Parmesan is already salty.
- Air fry: Arrange the cubes in an even layer and cook at 350°F for 5–7 minutes, flipping halfway. This is Beyond the Noms’ published setting, not a universal appliance guarantee.
- Check and serve: Look in around the midpoint. Remove pieces that are already deeply golden, and let the rest cook only until they reach the finish you want. Serve over salad or soup.
The method’s short cook and halfway flip are important because small pieces can brown quickly. Follow your air fryer’s manual, and avoid assuming that a full basket will cook like a single, even layer.
Why recipe times and temperatures differ
Published croissant recipes use different settings, so treat them as recipe-specific starting points rather than interchangeable instructions.

|---|---|---|
| Beyond the Noms, air fryer | 350°F for 5–7 minutes; flip halfway | Roughly 1/2-inch cubes; rosemary, garlic powder, Parmesan, salt, and pepper |
| Modern Bites, air fryer | 400°F for 5–6 minutes | Cubes coated with olive oil, garlic, garlic powder, Italian seasoning, salt, and pepper |
| Kate Reid’s Epicurious oven recipe (2023) | 310°F for 15–20 minutes; toss every five minutes | Day-old croissants in roughly 1-inch pieces, with olive oil, salt, and pepper; oven method |
The 400°F setting comes from a separate recipe and should not be paired with the 350°F recipe’s timing as if that combination had been tested. Appliance design, cube size, basket load, and the result you prefer can all affect cooking. Food Network Kitchen says settings may vary by air-fryer model and recommends consulting the manual; its general air-fryer crouton recipe is not croissant-specific. GE Appliances notes that its recipe was developed for GE Profile equipment and results can differ on other ovens.

Seasoning ideas and serving
Croissants bring buttery layers, so the seasoning can be simple. Try rosemary and Parmesan for a savory topping, or use the Modern Bites combination of olive oil, garlic, garlic powder, Italian seasoning, salt, and pepper. Add seasonings sparingly at first, then adjust the next batch to suit your taste. Scatter the finished pieces over salad or soup shortly before serving to preserve their texture.
What “best” means here
Croissant croutons have a clear appeal: they turn leftover pastry into a rich, flaky topping with little cooking time. But the available recipes are not head-to-head tests, and none establishes that croissant croutons are objectively the best. If you want a lighter result, stop when the pieces are just golden; for a more deeply toasted bite, cook longer while checking often. Your preferred finish—and what you are topping—decides whether they are best for you.
