Air fryer french onion soup isn’t a gimmick, I promise. Instead, this recipe uses science to take a 2 hour dish into a 60 minute one. By dehydrating the onions slightly in the air fryer, the onions caramelize much quicker and deeper in the pan. The result is a wonderfully complex soup that is as comforting as they come (and truly not that terrible for you). Air fryer french onion soup will become one of your favorite soup recipes, I assure you!
Air Fryer French Onion Soup
- 3 tablespoons butter
- 6 cups sliced onions (thats about 6 onions)
- 2 teaspoons fresh thyme
- 1 teaspoon soy sauce
- 1/2 teaspoon salt
- 1 bay leaf
- 6 cups low sodium beef stock
- 4 thick slices sourdough
- 2 cups shredded Provolone cheese
- Set your air fryer to 300 degrees. Line the basket with foil if you like, and cook sliced onions for 30 minutes to dry out. Stir often.
- Heat a large pot or dutch oven over medium heat. Add butter, onions, thyme, soy, and salt to the onions. Cook for another 15-20 minutes or until caramel and brown. Add in beef stock and bay leaf, and bring to a simmer. Simmer for at least 10 minutes (as you prepare the rest of the ingredients), though you can slow cook for several hours if you have it.
- Set broiler on high. Arrange 4 soup bowls (oven safe would be wise) on a baking sheet. Transfer the soup to the bowls, covering with the bread and the cheese evenly. Broil for 3-4 minutes or until the cheese is beautiful. Serve as soon as you won’t burn your mouth.
