Air Fryer Croutons

Store-bought croutons are usually stale, oddly salty, and full of oil you cannot taste. Homemade ones take about ten minutes, cost almost nothing, and let you use up the end of a loaf that is too dry for sandwiches. The air fryer is the fastest way to make them. Hot air circulates around every cube at once, so they crisp evenly without heating up the whole kitchen or babysitting a sheet pan in the oven. New to the appliance? Our guide to baking in an air fryer covers the basics.

The tricky part is not the method, it is picking a temperature. Search around and you will see everything from 325°F to 400°F, which is confusing when all you want is crunchy bread. So let me give you the clear answer first, then explain how to adjust it for your bread and your machine.

What temperature and how long to air fry croutons

That 375°F middle ground is the sweet spot for most breads and most air fryers. It is hot enough to brown and dry the bread in one short session, but not so hot that the outside scorches while the inside is still soft. If you want a quicker, darker, more toasted crouton, you can push to 390°F to 400°F and watch closely from the 4 minute mark. If your bread is thin or already dry, drop to 350°F so it does not burn.

Why every recipe gives a different temperature

If you have compared a few crouton recipes and felt lost, you are not doing anything wrong. The numbers really are all over the place, and there is a reason for each one. Here is what is actually going on so you can pick with confidence instead of guessing.

The other reason times vary so much is that air fryers are not standardized. A compact basket model runs hotter and closer to the food than a large oven-style one, so the same cube can be perfect in 4 minutes in one machine and need 8 in another. Bread density matters too. A dense sourdough cube holds more moisture and takes longer than an airy slice of white. This is why the honest instruction is always a range plus a look for the color, not a stopwatch. Once you have made a batch in your machine, you will know your number. If you often adapt oven recipes, our air fryer baking conversion guide explains the temperature math behind all of this.

Why you'll love making croutons in the air fryer

• Fast. Prep to bowl in about 10 minutes, faster than a trip to the store.
• Zero waste. The best use there is for a heel, a stale slice, or an orphaned bun.
• Less oil than the oven. A tablespoon coats a whole batch because the circulating air does the crisping.
• Fully yours. Garlic, herb, cheesy, spicy, or sweet cinnamon sugar. You control every pinch.
• No hot kitchen. No preheating a full oven for a handful of bread cubes.

Ingredients

One thing worth knowing up front: 4 cups of bread cubes is roughly 6 ounces, which is about 4 to 5 slices of sandwich bread or a quarter of a large sourdough boule. That saves you weighing anything. If you are doubling the batch, work in two rounds so the basket stays in a single layer.

Best bread for air fryer croutons

Almost any bread will crisp up, but they do not all behave the same way. Here is how the common choices actually cook so you can match the bread to the result you want.

• Sourdough. My favorite. Sturdy, tangy, and it holds a great crunch without turning to dust. Cook a minute longer since the cubes are dense.
• French bread or baguette. The classic. Crisp shell, open crumb, browns fast, so watch it near the end.
• Ciabatta. Light and airy with big holes. Crisps quickly and can fly around, so see the trick below.
• White sandwich bread. Always in the house, works fine, and cooks a little faster. Lower to 350°F so it does not scorch.
• Whole wheat. Nutty and hearty, a slightly denser crumb, cooks much like sandwich bread.
• Gluten-free bread. Works well and often crisps even harder. Check a minute early.

You do not need stale bread, which is the myth that trips people up. Fresh bread works because the air fryer dries it out as it cooks. That said, day-old bread is easier to cut into clean cubes and soaks up a touch less oil, so if you happen to have some, use it. If you like a fully homemade version, a loaf of our air fryer bread makes excellent croutons once it is a day old.

How to make air fryer croutons, step by step

1. Cut the bread into even ¾-inch cubes. Use a serrated knife so you do not squash the loaf, and keep the sizes uniform so they finish together. For a rustic look you can tear soft bread by hand instead.

   

2. Add the cubes to a bowl and drizzle over the oil. Toss first so every piece gets a light coat, which helps the seasoning stick and the surface crisp.
3. Sprinkle in the garlic powder, Italian seasoning, salt, pepper, and parmesan if using. Toss again until evenly coated with no dry patches.

   

4. Preheat the air fryer to 375°F (190°C) for 2 to 3 minutes. A warm basket starts crisping the moment the bread goes in.
5. Spread the cubes in a single layer, not crowded. Overlapping bread steams instead of crisping, so use two batches if your basket is small.

   

6. Air fry at 375°F for 6 to 8 minutes, shaking the basket at the halfway mark. Start checking at 5 minutes, since croutons go from golden to too dark quickly.
7. Tip them onto a plate and let them cool completely. They keep crisping as they cool, so the final crunch happens off the heat, not in the basket.

How to stop croutons flying around the basket

This is the one thing nobody warns you about. Light, airy bread like ciabatta or thin white slices can get picked up by the fan and thrown against the top of the air fryer, where they can hit the heating element. It is harmless but annoying, and it stops the cubes browning evenly. Two easy fixes:

Olive oil or butter for croutons?

Both work, and the choice is about flavor, not technique. Olive oil browns more evenly and gives a cleaner, savory crouton that suits most salads. Melted butter gives a richer, steakhouse-style crouton, the kind you get on a good Caesar, though it can brown a little faster so keep an eye on it. If you cannot decide, use half of each and get the best of both. For a dairy-free batch, olive or avocado oil is the way to go.

Flavor variations to try

• Garlic parmesan. Add 2 tablespoons grated parmesan with the seasoning. A crowd favorite on Caesar salad.
• Cacio e pepe. Heavy on black pepper and parmesan, skip the herbs. Great on tomato soup.
• Spicy Cajun. Swap the Italian seasoning for Cajun spice or add a pinch of cayenne and smoked paprika.
• Ranch. Toss with a teaspoon of dry ranch seasoning for a snacky, tangy crouton.
• Cheesy vegan. Use nutritional yeast in place of parmesan for a savory, dairy-free hit.
• Cinnamon sugar. For sweet croutons, use melted butter, cinnamon, and sugar. Lovely on a bowl of squash soup or as a snack.

Ways to use homemade croutons

Salad is only the start. Once you have a jar of these on the counter you will find uses fast:

• The obvious one, piled on a Caesar or a Greek salad.
• Floated on tomato, butternut squash, or French onion soup.
• Crushed into breadcrumbs for meatballs, meatloaf, or a crispy pasta topping.
• Stirred into stuffing or a savory bread pudding.
• Straight from the bowl as a snack, which is honestly where half of every batch goes.

They also make a great crunchy topper for a bowl of soup, or crushed over soft eggs on air fryer toast, where the contrast of crisp bread against soft egg is the whole point.

Troubleshooting

• Croutons came out chewy, not crisp. They needed a little longer, or the bread was very fresh and moist. Give them 1 to 2 more minutes, and remember they crisp further as they cool.
• They burned before crisping through. Too hot, or cut too small. Drop to 350°F and cut slightly bigger cubes next time.
• Some are done, some are soft. The cubes were uneven or crowded. Cut to a uniform size and keep a single layer.
• Bread is blowing around. Weigh it down with a trivet, and make sure the cubes are well coated in oil. See the section above.
• Seasoning fell off. Toss in oil first, then add the dry seasoning so it has something to cling to.

Storage and reheating

Let the croutons cool completely first. Warm croutons release steam in a sealed container and turn soft. Once cool, store them in an airtight container or a zip-top bag at room temperature for up to a week. Skip the fridge, since the moisture in there softens them.

To freeze, spread the cooled croutons on a tray until firm, then transfer to a freezer bag for up to 2 months. To bring back the crunch, whether from the counter or the freezer, air fry at 350°F (175°C) for 2 to 3 minutes and let them cool again.
