- Butter: Use salted or unsalted butter; just make sure you take the type of butter you used into account when seasoning.
- Onions: Yellow onions are best here because of their subtle sweetness.
- Thyme: This is a classic herb used in French onion soup recipes. I recommend fresh, but you could use one teaspoon of dried thyme if you don't have fresh.
- Salt: Adjust the salt to your taste. I recommend sea salt or kosher salt.
- Pepper: Use freshly ground black pepper for the best flavor.
- Garlic: A must in any good soup recipe!
- Sherry: Cooking sherry is a type of fortified wine found in most grocery stores' cooking aisle, next to the vinegar. You could also use white wine if you prefer.
- Beef Broth: I like to use low sodium or homemade to control the amount of salt in the soup.
- Worcestershire Sauce: This is a classic ingredient in French onion soup and adds an excellent depth of flavor.
- Baguette: Thick slices of French bread are the perfect way to finish Ninja Foodi onion soup
- Gruyere Cheese: This is a type of cheese that melts beautifully and has a slightly nutty flavor.
Tips & Tricks
- Slicing the onions: I like to slice my onions thinly so that they cook evenly and melt into the soup. If you have a food processor, you could use that to slice the onions quickly.
- Cooking the onions: Take your time cooking the onions until they are a deep golden brown color. This will take at least 15 minutes. The longer you cook them, the more flavor they will have.
- Adding the sherry: Be sure to deglaze the pan after adding the sherry. This means scraping up all of the brown bits from the bottom of the pan. This adds flavor, and scraping helps to prevent the soup from burning. You will want to use a silicone spoon to scrape your Ninja, as a metal spoon can destroy the coating.
- Serving: I like to serve this soup with a slice of baguette and some gruyère cheese melted on top. You could also use Swiss cheese or mozzarella cheese if you prefer.
This Ninja french onion soup would be great served with a salad for a light lunch or dinner. For a heartier meal, you could serve it with some roasted chicken or beef.
Frequently Asked Questions
Why is it called French onion soup?
Many theories exist about how French onion soup got its name.
One view is that it was created by the French chef Antonin Carême.
Another theory is that it was created in a French restaurant in New York City called Delmonico's. Whatever the true story, we know that this soup is a classic!
What can you not cook in an air fryer? Can I use the air fryer function to make this soup?
While the air fryer function is perfect for crisping up the bread in this recipe, anything that is too watery, like soup, does not work well in an air fryer.
This is because the fan blows the soup too much and will create a big mess in your Ninja Foodi.
For this reason, I don’t recommend using the air fryer function for cooking the soup.
Can you put metal in a Ninja Foodi?
Using a metal spoon to stir the soup is not recommended as it can damage the coating on the inner pot.
Instead, use a silicone or wooden spoon.

Store leftover Ninja Foodi French Onion Soup in the fridge for 3-4 days or in the freezer for 2-3 months.
To reheat, simply place the soup in a pot on the stove over medium heat. You may need to add a splash of water or beef broth if the soup has thickened too much.
Once heated, ladle into oven-safe bowls and broil the cheese on top of the toast. (Alternatively, you can cook the toast in your Ninja Foodi or on a baking sheet under the broiler.)
How to Make
First, start by selecting Sear/Sauté on your Ninja Foodi. Set the temperature to high.
Next, add ¼ cup of the butter to the pot. When the butter melts, add the onions, thyme, salt, and pepper to the pot and cook for 5 minutes.
After that, reduce the temperature to medium (3), and cook for another 10 minutes, stirring the vegetables occasionally. Then, add the garlic and cook for 1 more minute.
After the garlic has cooked, add the cooking sherry and cook for 2 minutes, scraping up any browned bits.
Make sure you use a wooden or silicone spoon to avoid scraping the bottom of the pot.
Then, add the beef broth and Worcestershire sauce. Hit cancel and close the pressure lid. Slide to pressure cook and ensure the steam release knob is in the seal.
Finally, select pressure, manual, and set the timer to 15 minutes. Select Start.
When the time is complete, do a quick release of the pressure by moving the pressure release valve to the vent position.
Carefully transfer the soup to serving dishes.
Toasting the Bread
Spread the remaining butter on the bread slices.
Add the air fryer basket to the inner pot and arrange the toast. Add the cheese to the top of the bread.
Close the crisping lid. Select air fry, 390 ° F, and set the time to 5 minutes. (You could also use the broil function.) Hit start.
When the time is up, carefully remove the french baguette slices from the Foodi and serve them over the soup.
