Yield
4 cups
3 cups gluten-free buttermilk cornbread, cut into ¾-inch cubes
¼ cup grated Parmigiano-Reggiano cheese
Preheat the Oven
Preheat your oven to 350°F. Prepare a large baking sheet by lining it with parchment paper or lightly greasing the surface.
A properly preheated oven helps the croutons dry out evenly while developing a crisp exterior and beautiful golden color.
Prepare the Cornbread
Cut the gluten-free buttermilk cornbread into approximately ¾-inch cubes. Using slightly stale or day-old cornbread is ideal because it contains less moisture and crisps more effectively during baking.
Arrange the cubes in a single layer on the prepared baking sheet. Avoid overcrowding the pan, as proper air circulation helps create evenly toasted croutons.
Add the Parmesan Cheese
Sprinkle the grated Parmigiano-Reggiano cheese evenly over the cornbread cubes. The cheese melts slightly as the croutons bake, creating a rich, savory flavor and helping the exterior become beautifully golden.
Bake Until Golden and Crispy
Place the baking sheet in the preheated oven and bake for approximately 40 minutes.
Stir the croutons once or twice during baking to ensure they brown evenly on all sides. Continue baking until the cubes are crisp, golden brown, and dry throughout.
The exact baking time may vary slightly depending on the moisture content of your cornbread.
Cool Completely
Remove the baking sheet from the oven and allow the croutons to cool completely before serving.
As they cool, the croutons will continue to crisp, resulting in an even crunchier texture.
The Best Ways to Use Gluten-Free Cornbread Croutons
One of the reasons these homemade gluten-free croutons are so popular is their versatility. Their hearty texture and rich flavor make them suitable for a wide variety of dishes.
Add them to garden-fresh salads filled with lettuce, cucumbers, tomatoes, and herbs from your backyard garden. The crunchy texture provides the perfect contrast to crisp vegetables and creamy dressings.
Sprinkle them over classic soups such as tomato soup, potato soup, broccoli cheddar soup, corn chowder, or butternut squash soup. The croutons absorb just enough liquid while maintaining their satisfying crunch.
These gluten-free soup toppings are also delicious on hearty chili recipes. Whether you prefer beef chili, turkey chili, white chicken chili, or vegetarian chili, cornbread croutons add flavor and texture that pair beautifully with bold spices.
You can even use them as a topping for baked casseroles, macaroni and cheese, roasted vegetables, and stuffing-inspired holiday side dishes.
Flavor Variations
This cornbread crouton recipe is easy to customize.
For garlic Parmesan croutons, toss the cornbread cubes with garlic powder before baking.
For an herbed version, add dried thyme, rosemary, parsley, or Italian seasoning.
For a smoky flavor, sprinkle the cubes with smoked paprika before baking.
For a spicy variation, add a pinch of cayenne pepper or chili powder.
These simple additions allow you to create different flavors to complement a variety of meals.
Storage Tips
Once completely cooled, store the croutons in an airtight container at room temperature.
They will stay fresh and crispy for up to 5 days. If they begin to soften, simply place them back in a 350°F oven for a few minutes to restore their crunch.
You can also freeze baked croutons for longer storage. Place them in a freezer-safe container and freeze for up to 3 months. Reheat directly from frozen in a warm oven until crisp.
Day-old gluten-free buttermilk cornbread produces the best results because it contains less moisture.
For extra-crispy croutons, turn off the oven after baking and leave the croutons inside for an additional 10 minutes.
Freshly grated Parmigiano-Reggiano provides the best flavor and texture.
These homemade gluten-free croutons make an excellent addition to meal prep because they can be prepared in advance and used throughout the week.
These homemade gluten-free cornbread croutons are simple to make and require only a handful of ingredients. They are naturally flavorful, wonderfully crunchy, and incredibly versatile.

Another advantage of making homemade gluten-free croutons is that they can be customized to suit your tastes. Add herbs, spices, or seasonings to create unique flavor combinations that work with different meals throughout the week.
