Save a little time with this Paleo instant pot onion soup recipe. It achieves that classic flavor with only Paleo ingredients.

Why Other Onion Soups Aren’t Paleo

Like many foods, onion soup seems safe enough for Paleo. There’s not a whole lot to it, and the star of the dish is the onion.

How could it not be Paleo?

Recipes and restaurants like to slip in things that are off-limits for the Paleo crowd. A quick search revealed a few potential culprits.

One recipe calls for a few tablespoons of flour. While it’s not much, it’s also not necessary, and you’ll appreciate not going down the grain path.

Another recipe called for sugar. While they only included a teaspoon, onion soup is best served savory, and your body certainly doesn’t need any extra sugar.

And last but not least, let’s talk about the elephant in the room (kitchen?) – cheese.

Is Cheese Paleo?

It depends. There are definitely people in the Paleo world that believe that cheese is strictly off-limits, and many people have sensitivities to it anyway.

Personally, I would recommend eliminating dairy for a month or so when you start Paleo. If you’d like to try reintroducing it into your diet, use raw cheese.

If you still feel OK on raw cheese, feel free to keep eating it. Or, if you’d like more information on the subject, check out this article.

If you would like to include cheese in this recipe, Gruyere is a popular choice. Prepare to shell out a little more than your standard shredded bag of mozzarella though.

The Trick to This Dish

I don’t know about you, but I’m not a fan of gnawing on raw onions. That’s a little…intense…to say the least.

When you cook and caramelize onions, however, you get this magical jammy sweetness and all of that bite has been cooked away.

That’s what you want for this soup: a very jammy, soft, translucent onion. Be very careful not to let them burn, however.

Winter is soup time, and if you’re a soup person you’re in luck – there are a lot of options for you on Paleo.

Paleo Instant Pot Onion Soup Recipe

  • Author: Louise Hendon
  • Prep Time: 10 minutes
  • Cook Time: 45 minutes
  • Total Time: 55 minutes
  • Yield: 2 servings 1x
  • Category: Soup
  • Cuisine: French


A French classic made Paleo.


  • 2 Tablespoons (30 ml) of olive oil
  • 2 medium onions (220 g), peeled and sliced
  • 2 garlic cloves (6 g), peeled
  • 3 cups (720 ml) of best-quality fresh beef broth (warm)
  • 1 Tablespoon of Madeira (optional)
  • salt and freshly ground black pepper
  • fresh parsley, to garnish


  1. Heat the olive oil in a pressure cooker on the stove top and add the sliced onions. Cook over moderately high heat until they darken and caramelize. Add the garlic and continue to cook the mixture until very dark and jammy. Do not allow the mixture to burn, but you want to get a lot of color on the onions.
  2. Pour in the warm beef broth and bring to a simmer. Secure the lid of the pressure cooker and cook under full pressure for 30 minutes.  Allow the pressure cooker to decompress before safely removing the lid.
  3. Season the soup with the salt and freshly ground black pepper. Add the optional Madeira if you’d like. Pour into a bowl and garnish with fresh parsley.
