From adding a savory crunch to salads and soups to serving as a flavorful topping for sandwiches and wraps, crispy fried onions bring a burst of flavor and texture to every bite.

Why Avoid Deep Frying?

While deep frying is a traditional method for achieving crispy onions, it comes with several drawbacks.

Deep frying requires large amounts of oil, which can be unhealthy and add unnecessary calories to your dish.

Additionally, the process of deep frying can be messy and time-consuming, involving splattering oil and lingering odors in your kitchen.

The Secret to Crispy Perfection: Oven-Baked Method

Fortunately, there’s a simpler and healthier alternative to deep frying—oven-baking! By using your oven instead of a deep fryer, you can achieve the same crispy texture and delicious flavor without the excess oil and mess.

Here’s how to make crispy fried onions using the oven-baked method:


  • 2 large onions, thinly sliced
  • 2 tablespoons of olive oil
  • Salt and pepper to taste


  1. Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper or aluminum foil.
  2. In a large bowl, toss the thinly sliced onions with olive oil, ensuring that they are evenly coated.
  3. Spread the coated onions in a single layer on the prepared baking sheet, making sure they are not crowded.
  4. Season the onions with salt and pepper to taste, giving them an extra flavor boost.
  5. Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the onions are golden brown and crispy, stirring occasionally to ensure even cooking.
  6. Once crispy, remove the baking sheet from the oven and let the fried onions cool for a few minutes before serving or storing.

Tips for Perfectly Crispy Onions:

Thinly Sliced Onions:

For optimal crispiness, slice the onions as thinly as possible.

This ensures that they cook evenly and become crispy rather than soggy.

Even Coating of Oil:

Make sure that the sliced onions are evenly coated with olive oil before baking.

This helps to achieve a crispy texture and prevents them from sticking together.

Single Layer on Baking Sheet:

To ensure that the onions crisp up evenly, spread them out in a single layer on the baking sheet.

Crowding the onions can result in uneven cooking and soggy texture.

Regular Stirring:

While baking, stir the onions occasionally to ensure that they cook evenly and don’t burn.

This helps to achieve a uniform golden brown color and crispy texture.


With this simple oven-baked method, you can enjoy the irresistible crunch of crispy fried onions without the hassle of deep frying.

By thinly slicing the onions, coating them with olive oil, and baking them to golden perfection, you’ll create a delicious and healthy topping for all your favorite dishes.

So say goodbye to the mess and calories of deep frying, and hello to crispy perfection with oven-baked fried onions!
