Oven-Baked Crispy Onions (Gluten-Free)

My Danish husband loves to sprinkle crispy onions on his food, especially open sandwiches.

We buy one brand from Whole Foods, which is pretty decent but not something I would eat. I love onions, and adding them to meals seems like a good idea, so I decided to make my own.

Oven-Baked, No Mess

It wasn’t hard. I used one egg, so it remains to be seen if they can be made without eggs. I know they can if they are deep-fried, but these are baked in the oven, and it’s a bit harder to reach crispiness that way.

Anyway, until I test the egg-less version, this one is pretty good if eggs are part of your diet.

Later edit: I did try a version without eggs and didn’t like it.

One medium red onion makes quite a large quantity, mainly if we only use them as a topping. But the baked onions are great even as a side dish, and they will add another layer of taste and texture to your meals.

Ingredients

• 1 medium red onion
• 1 pasture-raised egg
• 1 tablespoon extra virgin olive oil
• 2 tablespoons cassava flour
• salt and pepper

How to make crispy onions in the oven

Preheat the oven to 400F.

Cut the onion in half and then thinly slice each half as finely as possible, ensuring the slices are not attached.

Beat the egg in one large bowl, add the extra virgin olive oil, 1/8 teaspoon salt, and freshly ground pepper and combine, then add the onions to the bowl, and with your hands, mix the onion and the egg, so the onion slices get coated with the egg.

Take the onion from the bowl leaving behind the remaining liquid, and spread it on a large stainless steel baking sheet so it overlaps as little as possible.

Add one tablespoon of the flour to a sieve and sift it over the onions. Mix them around the sheet with two forks, and repeat with the second tablespoon of flour. Mix again with the forks and spread the onions on the baking sheet.

Bake for about 20 minutes, stir again with tongs or forks, and bake for 15 more minutes or until they are crispy. Take them out and let them cool on the baking sheet.

Serve warm or cold.

How to use crispy onions

You can add the roasted onions on top of eggs, sauteed vegetables, and baked sweet potatoes, or mix them with pressure-cooked beans for a warm or cold salad. They also make a good topping for dips such as:

• Beef Liver Pate with Fresh Herbs
• Creamy Artichoke Spread
• Cauliflower and Artichoke Hummus with Roasted Garlic
• Sweet Potato Hummus

And of course, they’ll make a great burger topping.

Notes

You can store leftovers in a glass container in the refrigerator, but they won't stay super crispy. But you can pop them in the oven again, and they'll get crispy.
