Making low carb simple

Instructions

Instructions are for 4 servings. Please modify as needed.

  1. Heat the coconut oil in a large pan, over medium low heat.

  2. While the oil heats, whisk the eggs together with 1/3 oz. (about 1.5 tbl) coconut flour and a pinch of salt. Whisk until the ingredients are blended.

  3. Combine the rest of the dry ingredients in another medium sized bowl.

  4. Using a fork, completely coat each onion ring with the beaten egg, and then lift and drop the coated onion ring into the flour mixture. Spoon the flour mix over the entire ring, and gently move the rings to a plate.

  5. Add some rings to the pan, leaving space in between each ring. Fry for about 3-4 minutes per side, until golden brown, and then remove to a plate lined with paper towels to cool. Continue this process until done, and then salt to taste.

Ps. This is a new and improved recipe. The old onion ring recipe is replaced with this one. We hope you'll love this one even more!

Tip

Using a fork, versus tongs or a spatula is an easy and gentle way to flip the onion ring without disrupting the coating.

You can fry in tallow, or other fat with a high heat point if you don't like coconut oil.

The batter may be quite thick and stiff, so thin it with either cream or water to a pancake-like batter consistency. Then dip the onion rings in this, placing gently into the low-moderate heated oil.

    a third of an ounce? May as well use cubits and pennyweights. Stop pandering to one country and use 21st century weights and measures please. An ounce is closer to 30g than 25g.

    Coconut flour is very much an acquired taste, I tried these anyway because the picture looked so good, but sure enough they didn't really do it for me. Disappointing.

    Olive Oil at high temperatures oxidizes which causes oxidation. Use animal fats for frying. Fruit oils for finishers or low heat cooking.

    If you have an egg white allergy, surely you must already know what you can use instead when you are following recipes ?
    If not, have a look here. But I doubt the DD team has tried any of them in this recipe.

    The instructions don't convert though, which is the part biggus is mentioning "While the oil heats, whisk the eggs together with 1/3 oz. (about 1.5 tbl) coconut flour and a pinch of salt. Whisk until the ingredients are blended."

    Only the ingredients convert.

    Laura, I understand your point: air fryers are a great innovation for those concerned about dietary fat. However, on a LCHF or ketogenic regimen, cooking with and consuming animal fat is not "taboo." Also, not everyone has the kitchen storage and/or counter space for more appliances, or the budget to purchase them. I like that this recipe for fried onion rings requires no special equipment.

    PATRICIA

    February 20 2020

    Dr. Laura A, measuring cups and spoons (for solids, not liquids) measure "volume" whereas "ounces" is an expression of "weight." Consider: a tablespoon of feathers weighs much less than a tablespoon of lead ball bearings. I use my digital kitchen scale to measure non-liquid ingredients by weight.

    I watched your little tutorial video before making my first batch of these gorgeous onion ring treats tonight.

    They are tasty, crunchy, and very more-ish!

    Served them with your bite size breaded fish as a special treat during this enforced lockdown of Covid19.

    Thank you, My husband has lost nearly 2 stones following your recipes, and my blood sugar level has improved too.

    I made these tonight to go with pork and green beans. It was a special treat. I followed the recipe pretty much as described. I used olive oil instead of coconut oil and it worked ok. The oil was all thick and gummy by the last batch though. The taste was wonderful though. I served it with homemade ranch. Being able to enjoy some of my old favorites makes this way of eating sustainable for me!! Thanks DD.

    I was reading back through the recipe. The parmesan in the video is grated (sort of like a dry flour). The recipe says to use shredded parmesan. Is this correct or should it be changed to grated? Yes, I am being specific because I use grated which mixes well with grain free flours and helps coat foods.

    Hi, Shondra! Either one would work fine. You can use whichever you prefer!

    I found 1tbsp coconut flour enough to mix with the egg otherwise it gets too thick.
    The flavour was enhanced with the addition of 1tsp onion granules.
    I think this would work well as a chicken coating too...... I shall try and report back!
