Frequently Asked Questions About Croutons
Croutons seem simple, but many home cooks have questions about making them perfectly crispy, storing them properly, and choosing the right ingredients. These frequently asked questions cover everything from basic preparation to advanced techniques, helping you create restaurant-quality croutons at home.
The answers below draw from culinary science, professional chef techniques, and practical home cooking experience. You'll find specific measurements, temperatures, and timing that take the guesswork out of crouton preparation.
What are croutons made of?
Croutons are small cubes of bread that have been seasoned and baked or fried until crispy. They're typically made from day-old bread, olive oil or butter, and various seasonings like garlic powder, dried herbs, salt, and black pepper. Commercial versions often include cheese powder, particularly for caesar-style croutons, and may contain preservatives to extend shelf life. The bread base can be white, whole wheat, sourdough, or specialty breads like bagels or rye. The key is using bread that's 1-2 days old because it has lost enough moisture to crisp properly without becoming rock-hard. High-quality homemade versions use extra virgin olive oil and fresh seasonings, while store-bought varieties may use vegetable oils and dried flavorings for consistency and cost efficiency.
How do you make homemade croutons?
Cut bread into uniform 0.75-inch cubes and place them in a large bowl. For every 4 cups of bread cubes, drizzle 3-4 tablespoons of olive oil and add your chosen seasonings (typically 0.5 teaspoon salt, 0.25 teaspoon garlic powder, and 0.25 teaspoon dried herbs). Toss everything together until the bread is evenly coated. Spread the cubes in a single layer on a baking sheet, ensuring they don't touch. Bake at 375°F for 10-15 minutes, stirring halfway through for even browning. The croutons are done when they're golden brown and crispy on the outside but still slightly tender inside. Let them cool completely on the baking sheet before storing, as they'll continue to crisp up during cooling. For air fryer preparation, cook at 370°F for 5-7 minutes, shaking the basket every 2 minutes.
How long do croutons last?
Homemade croutons stay fresh for up to one week when stored in an airtight container at room temperature, away from direct sunlight and heat sources. The key to longevity is ensuring they're completely cooled before storage, as any residual warmth creates condensation that makes them soggy. Store-bought croutons typically last several weeks past their printed expiration date if the package remains unopened, thanks to preservatives and nitrogen-flush packaging. Once opened, treat them like homemade versions and use within 7-10 days. If your croutons lose their crunch, you can refresh them by spreading them on a baking sheet and heating at 300°F for 3-5 minutes. Avoid storing croutons in the refrigerator, as the moisture-rich environment will make them soft and chewy rather than crispy.
What kind of bread is best for croutons?
Day-old bread works best for croutons because it's slightly dried out, having lost 15-20% of its moisture content, which allows it to absorb seasonings well without becoming soggy. French bread and baguettes are popular choices for their light, airy texture and mild flavor that complements most dishes. Sourdough creates croutons with a tangy complexity that pairs exceptionally well with caesar salads and bitter greens like arugula. Whole wheat bread adds nutritional value with extra fiber and a nuttier taste. Ciabatta produces very crispy results due to its open crumb structure and crusty exterior. For richer applications like cream soups, challah or brioche work beautifully with their eggy, buttery character. Even specialty breads like pumpernickel for German-style salads or bagels for breakfast applications can create unique variations. The most important factor is that the bread should be sturdy enough to hold its shape when cut and tossed with oil.
Can you freeze croutons?
Yes, croutons freeze exceptionally well for up to 6 months when stored properly in an airtight container or heavy-duty freezer bag with as much air removed as possible. Freezing actually helps preserve their crispy texture better than extended room-temperature storage. You can use frozen croutons directly from the freezer without thawing, adding them straight to hot soups or salads where they'll thaw within seconds. For applications where you want maximum crispness, spread frozen croutons on a baking sheet and refresh them in a 300°F oven for 5-7 minutes. Avoid freezing croutons that have already been dressed or exposed to moisture, as ice crystals will form and destroy their texture. Label your container with the date, and try to use them within 3 months for best quality, though they remain safe to eat for up to 6 months. This makes batch-cooking croutons practical, allowing you to prepare large quantities when you have leftover bread.
Are croutons gluten-free?
Traditional croutons are not gluten-free because they're made from wheat-based bread, which contains gluten proteins. However, gluten-free croutons are increasingly available in stores and easy to make at home using gluten-free bread. Brands like Olivia's Croutons and Mrs. Cubbison's offer certified gluten-free options made from rice flour, tapioca starch, or other gluten-free grain blends. When making your own, choose a sturdy gluten-free bread rather than soft sandwich varieties, as firmer breads hold their shape better during cutting and baking. Gluten-free breads often contain more moisture than wheat breads, so you may need to reduce the oil slightly or extend baking time by 2-3 minutes. The texture will differ somewhat from wheat-based croutons, typically being slightly denser, but proper seasoning and baking technique still produces satisfying crunch. Always check labels on store-bought versions, as cross-contamination during manufacturing can be a concern for those with celiac disease.
Why are my homemade croutons soggy?
Soggy croutons result from one of four common mistakes: using fresh bread instead of day-old, overcrowding the baking sheet, using too much oil, or storing them before they've completely cooled. Fresh bread contains 35-40% water content, which prevents proper crisping and leaves a chewy center. When bread cubes touch each other on the pan, steam gets trapped between them, preventing the dry heat from creating a crispy exterior. Using more than 1 tablespoon of oil per cup of bread cubes oversaturates them, resulting in greasy, soft croutons rather than crispy ones. If you store warm croutons in a container, condensation forms and immediately softens them. To fix soggy croutons, spread them on a baking sheet and bake at 300°F for 5-8 minutes until they crisp up. For prevention, always use day-old bread, maintain space between cubes during baking, measure oil carefully, and let croutons cool completely on the baking sheet for at least 15 minutes before storage.
Can you make croutons without oil?
Yes, you can make oil-free croutons, though they'll have a drier texture and less rich flavor than traditional versions. The simplest method is cutting day-old bread into cubes, seasoning them with salt, garlic powder, and dried herbs, then baking at 350°F for 15-20 minutes until crispy. These work well for people following oil-free diets or wanting to reduce calories, as oil-based croutons contain 40-60 additional calories per serving from fat. For better flavor without oil, try using vegetable broth or tomato juice as a light coating before seasoning, which adds moisture for seasoning adherence without the fat content. Some cooks use aquafaba (chickpea liquid) as a binder that helps seasonings stick. Another option is an egg white wash, which creates a crispy coating while adding protein. The texture will be more similar to melba toast or zwieback than traditional croutons, but they still provide satisfying crunch for salads and soups. Baking time may need adjustment, typically requiring 3-5 minutes longer than oil-based versions to achieve proper crispness.
