How to Dry Roast Onions

How to Dry Roast Onions ~ roasted onions are about as elemental as it gets when it comes to a delicious side dish. These beautiful red onions literally bloom in the high heat of a 400 degree oven, and come out tender and delicious!

I was all set to make red onion rings for you today. The big thick juicy kind. But over the last couple of weeks I’ve been reading articles about problems associated with using oils at high heat levels. The old wisdom of choosing an oil based on its smoke point isn’t enough anymore. And all of the oils we associate with high heat cooking undergo unhealthy changes when heated. Some claim that only coconut oil, clarified butter, and lard are safe at high heat.

There’s a lot of controversy surrounding the subject, and we’re at that unsettling point where the old ‘facts’ are being debunked, but there’s no solid agreement on an alternative. At any rate is seems like a complete overhaul of my cooking oil cabinet will be in order very soon now.

So for the moment, lets not use any oils at all! Instead of the onion rings I’m going to dry roast these luscious red onions in a hot oven.

Take  your onions, either red, white or yellow, and cut them in quarters almost, but not quite, all the way through. My onions were on the large size, if yours are smaller, just make one slice.


Pry the onions apart a little bit and set them in a foil lined baking sheet or pan.

Roast them at 400F for about 2 to 2 and a half hours. The kitchen will smell amazing for that entire time.

Luckily there is no controversy about the fact that onions do very well with high heat. They will blossom and get all caramelized. Bon Appetit recommends drizzling the finished onions with browned butter, but I used my best olive oil and a generous sprinkling of one of one of my Spice Blends.

This is such an elemental way of cooking. It’s basically the equivalent of throwing the onions into the embers of your hearth fire and letting them roast away. It’s nice to know that while science is dithering over smoke points, trans fats and free radicals, we can still eat like kings.

Ingredients

  • small to medium red onions, do not peel

Instructions

  • Preheat oven to 400F
  • Use a sharp knife to slice through each onion almost into quarters, but not cutting through all the way, so the onion stays intact. Start your cuts at the top and leave the root end intact.
  • Pry the onions open slightly with your fingers and set them on a foil lined baking sheet or baking pan. Bake for 2 to 2 1/2 hours until soft and caramelized.
  • Serve the onions with a drizzle of olive oil, melted butter, or browned butter. Season with salt and pepper.

    I am also loving the coconut reprieve! I’ve been having some shredded coconut on my morning Greek yogurt lately.

    Gorgeous onion shots! Give me onions every day – love them!

    It hasn’t been that many years ago that we were told not to touch coconut oil with a 10 foot pole. Now it’s the new wonder food. My son just bought me a bottle at Trader Joe’s and I’m eager to try it. Excellent post, Sue.

      Thanks Cathy, I learned a lot reading up on the subject. I think the lesson I’m beginning to take from it all is that you can’t take any scientific study as gospel, you have to use common sense when it comes to your food.
