Revitalize stale sourdough bread by transforming it into crunchy, seasoned croutons using the rapid air circulation of your air fryer.
This method is faster and more energy-efficient than using your oven. It also gives you incredible control over the texture. You can make them as soft or as crunchy as you like. Best of all, it’s a great way to reduce food waste.
This guide will walk you through the entire process, from choosing your bread to storing the finished croutons.
How To Make Sourdough Croutons In Air Fryer
This section covers the core recipe and technique. The beauty of this method lies in its simplicity and speed. You only need a few basic ingredients to get started.
The most important ingredient is, of course, your sourdough bread. Stale bread is actually preferable here, as it has less moisture and will crisp up better. If your bread is very fresh, you can dry out the cubes slightly in a low oven for 10 minutes before seasoning.
Essential Ingredients And Equipment
You likely have everything you need already in your kitchen. Here is your basic shopping list.
- Sourdough Bread: About 4 cups of 1/2-inch to 3/4-inch cubes. Any variety works, from plain white sourdough to whole wheat or rye.
- Oil: 2-3 tablespoons of a good cooking oil. Olive oil, avocado oil, or melted butter all work wonderfully.
- Seasonings: Salt is essential. Beyond that, classic choices include garlic powder, onion powder, dried oregano, dried thyme, black pepper, and grated Parmesan cheese.
- Your Air Fryer: Any model will do. Basket-style or oven-style air fryers both produce excellent results.
- Mixing Bowl: A large bowl to toss the bread cubes with oil and seasonings.
Step By Step Instructions
Follow these simple steps for perfect croutons every single time. The key is even coating and not overcrowding the air fryer basket.
- Cut your sourdough bread into cubes. Aim for a consistent size, between 1/2-inch and 3/4-inch, so they cook evenly. Remove any very hard crusts if you prefer.
- In a large mixing bowl, drizzle the oil over the bread cubes. Use your hands or a spatula to toss until every cube is lightly and evenly coated. This is crucial for even browning.
- Sprinkle all of your chosen seasonings and salt over the oiled cubes. Toss again thoroughly to distribute the flavor.
- Preheat your air fryer to 350°F (175°C) for 3 minutes. While not always required, preheating helps start the cooking process immediately for a more uniform texture.
- Place the seasoned bread cubes in the air fryer basket in a single layer. Do not pile them on top of each other. You may need to cook in batches.
- Air fry for 5 minutes. Shake the basket or stir the croutons. Check for doneness. Air fry for another 3-5 minutes, shaking every couple of minutes, until they are golden brown and crispy to your liking.
- Immediately transfer the hot croutons to a plate or baking sheet to cool. They will crisp up further as they cool down.
Pro Tips For Perfect Air Fryer Croutons
A few small adjustments can make a big difference in your final product. Keep these tips in mind.
- Dry Bread is Best: Stale, day-old bread yields the crunchiest croutons. Fresh bread can work, but may result in a slightly chewier center.
- Don’t Skimp on Oil: The oil is what makes the seasonings stick and promotes that beautiful golden color. Every piece should glisten lightly.
- Season Generously: Bread cubes are bland on their own. Be bold with your seasonings, especially the salt.
- Shake Frequently: The hot air needs to circulate around all sides of the cubes. Shaking the basket every few minutes prevents burning and ensures even cooking.
- They Cook Quickly: Watch them closely after the 5-minute mark. They can go from perfect to burnt in a very short time.
Flavor Variations And Seasoning Ideas
The basic recipe is just the beginning. Once you master the technique, you can start experimenting with different flavor profiles to match any meal.

- 1 tsp garlic powder
- 1 tsp dried Italian seasoning
- 1/2 tsp onion powder
- 1/2 tsp salt
- 1/4 tsp black pepper
- 2 tbsp finely grated Parmesan cheese (add after cooking if your air fryer manual advises against cooking cheese)
Everything Bagel Seasoning
This trend translates perfectly to croutons, adding a wonderful savory, seedy crunch.

Storing And Using Your Homemade Croutons
Proper storage keeps your croutons crunchy for days. And their uses go far beyond just a Caesar salad.
Best Practices For Storage
Let the croutons cool completely before storing them. Any residual heat will create steam and make them soft.
- Airtight Container: Store cooled croutons in an airtight container or a resealable plastic bag.
- Cool, Dark Place: Keep them in your pantry or cupboard. They do not need to be refrigerated.
- Freezing: For longer storage, you can freeze them for up to 2 months. Spread them on a baking sheet to freeze solid first, then transfer to a freezer bag.
Properly stored, your homemade croutons will stay crisp for about 1 to 2 weeks. If they lose a little crunch, you can refresh them in the air fryer for 1-2 minutes at 350°F.
Creative Ways To Use Sourdough Croutons
Don’t limit these crunchy cubes to just salad. Here are several other ideas.
- Soup Topper: The classic use. They add perfect texture to creamy soups like tomato, broccoli cheddar, or potato leek.
- Stuffing Base: Use your seasoned croutons as the base for a quick stuffing or dressing. Just add sautéed vegetables and broth.
- Breadcrumb Substitute: Pulse them in a food processor to make coarse, flavorful breadcrumbs for topping casseroles or coating chicken.
- Snack Mix: Toss them with nuts, pretzels, and your favorite seasonings for a unique snack mix.
- Panzenella Salad: Make a traditional Italian bread salad by combining your croutons with ripe tomatoes, cucumbers, red onion, and a simple vinaigrette.
Troubleshooting Common Issues
Even with a simple recipe, sometimes things don’t go as planned. Here are solutions to common problems.
Croutons Are Burning
If your croutons are burning before they crisp up, the temperature is likely too high or they are overcrowded.
- Reduce the temperature to 325°F and extend the cooking time, shaking frequently.
- Ensure you are cooking in a single layer with space between cubes.
- Check your air fryer’s calibration; some models run hotter than the set temperature.
Croutons Are Not Crispy
Soft or chewy croutons are usually a sign of too much moisture.
- Your bread may have been too fresh. Use staler bread or dry fresh cubes in a 250°F oven for 10 minutes before air frying.
- You may have used too much oil, which can make them soggy. Use just enough to coat.
- They might be undercooked. Add 1-2 more minutes to the cook time, but watch closely.
Seasoning Is Not Sticking
The seasoning falls to the bottom of the bowl or basket if not properly adhered.
- Always toss the bread cubes with oil first, before adding any dry seasonings. The oil acts as a glue.
- You can also try tossing the seasoning with the oil in a small bowl first, then coating the bread cubes with this mixture.
Frequently Asked Questions
Can I Use Fresh Sourdough Bread?
Yes, you can use fresh bread. However, for the crispiest results, it is better to use stale bread or to dry out fresh cubes on a baking sheet in a low oven (250°F) for about 10 minutes before seasoning and air frying. This removes excess moisture.
What Is The Best Temperature For Air Fryer Croutons?
350°F (175°C) is the ideal starting temperature. It cooks the croutons quickly enough to get crispy without burning the outside before the inside dries out. If you find they are browning to fast, reduce to 325°F.
How Long Do You Put Croutons In The Air Fryer?
The total time is usually between 8 to 10 minutes at 350°F. This can vary based on the size of your cubes, your specific air fryer model, and how crispy you like them. Always start checking at the 5-minute mark and shake the basket frequently.
Can I Make These Croutons Oil-Free?
You can try, but the results will be different. The oil is critical for browning and helping the seasonings adhere. For a lower-oil version, use an oil spray to very lightly mist the cubes, ensuring you still get some coverage for browning.
Are Sourdough Croutons Healthier Than Store-Bought?
Homemade sourdough croutons are typically healthier. You control the quality and amount of oil, the type of salt, and you can avoid the preservatives and artificial flavors often found in commercial brands. Sourdough bread itself also has nutritional benefits due to its fermentation process.
