Ingredients for Instant Pot French Onion Soup
This ingredient list is a bit lengthy but don’t let that scare you away! Once you have all of these ingredients on hand then it’s a breeze to make! You won’t regret it. See the recipe card at the bottom of the post for exact measurements.
- Butter: I used unsalted butter in this recipe.
- Olive oil: You can use vegetable instead if that’s what you have on hand.
- Sweet onions: I used medium sized Walla Walla onions.
- Brown sugar: This really brings in a deep, sweet flavor to the soup.
- Dry white wine: This deglazes the bottom of the pot adding in more bits of flavor to the soup! You can use extra beef broth if you prefer to use that instead.
- Beef broth: This has a lot of protien and it adds that rich and hearty flavor to the soup.
- Worcestershire sauce: Even if you can’t say this name, you won’t want to miss out on this in the recipe!
- Minced garlic: Garlic is a must. I know that I love it but really, it adds a lot to the soup.
- Bay leaves and dried thyme: These herbs really pair well with the onions and beef broth.
- Salt and pepper: Use these to season to taste.
- Baguette: You can buy a baguette or two or make one at home with this recipe.
- Gruyere cheese: This cheese is a MUST for french onion soup! It’s traditional for french onion soup for a reason! Don’t substitute this.
