What are Fried Onions?
Fried onions are thinly sliced onions pan-fried or deep-fried until they turn golden brown and crisp. They add a savory crunch and a burst of onion flavor to many dishes.
Use them as a garnish, an appetizer, or a snack. They pair beautifully with mashed potatoes, creamy soups, green bean casserole, salads, grain bowls, or simply eaten on their own.
Why This Recipe Works:
- Minimal Ingredients: This recipe uses only a few pantry staples, keeping things simple and budget-friendly.
- Quick Prep: About 10 minutes of prep is all you need before frying to golden crisp.
- Crispy Texture: A light coating creates a satisfying crunch that enhances soups, casseroles, and more.
- Allergen-Friendly: The recipe is naturally gluten-free, dairy-free, and vegan, suitable for many dietary needs.

Recipe Notes + Substitutions:
- Onion variety: Yellow onions work well, but white or red onions can be used for different flavor profiles.
- Coating: Cornstarch gives a light, crisp coating. For a gluten-free alternative use a gluten-free all-purpose flour blend that contains rice flour, tapioca, potato starch, or similar. Regular flour works if gluten is not a concern.
- Oil: Neutral oils with a high smoke point are best—sunflower, canola, or avocado oil are good choices. Olive oil can be used, though its flavor is more pronounced.
- Seasoning: Adjust with salt and freshly ground black pepper. For extra flavor, mix in a pinch of garlic powder, onion powder, or paprika with the starch before tossing the onions.
How to Make Gluten-Free Fried Onions (Step by Step):
1. Peel and Cut Onions
Peel the onions and slice them into thin, even strips so they cook uniformly.
2. Coat Sliced Onions with Cornstarch
Place the sliced onions in a large bowl, add cornstarch, and toss until each piece is lightly coated. Wearing disposable gloves makes this quick and tidy.
3. Heat Up Oil
Heat a few tablespoons of oil in a large skillet over medium-high heat until hot. Add the coated onions in a single layer—do not overcrowd the pan.
4. Fry Until Crispy
Fry, stirring occasionally, until the onions turn golden and crisp, about 5–6 minutes. If needed, fry in batches so each piece has room to crisp properly.
5. Absorb Excess Oil
Remove the fried onions with a slotted spoon and transfer them to a plate lined with paper towels to drain and crisp as they cool.
Tips & Tricks:
- Onion choices: Sweet varieties like Vidalia or standard yellow onions work well; red onions add a sharper flavor and color.
- Deep-frying option: For classic French-fried onion texture, deep-fry in a pot with 2–3 inches of oil. Be mindful of safety and oil temperature.
- Onion rings: To make rings instead of straws, slice the onion crosswise into rings, coat, and fry.
- Season the coating: Add spices to the cornstarch—garlic powder, onion powder, or smoked paprika—to customize the flavor.
What to Eat with Crispy Onions:
These fried onions pair well with many dishes. Try them on:
- Mashed potatoes
- Creamy soups (potato, mushroom, or chowders)
- Green bean casserole
- Roasted or air-fried green beans
- Grain bowls and salads for added crunch
Recipe FAQs:
Allow the fried onions to cool completely, then store them in an airtight container. Cooling fully prevents steam from making them soggy.
