What is the Best Cheese for French Onion Soup?

If you are worried about french onion soup cheese there are a few options. Personally I love the taste of Gruyere cheese on french onion soup.

If you are struggling to find either one, swiss cheese will work in a pinch.

Whenever I am serving soup I like to also make Cheddar Keto Biscuits or Keto Copy Cat Red Lobster Biscuits.

Thinly sliced onions. You want to have thin slices of onions when you are making this soup.

Do not stir the onions right away. When you are cooking the onions you do not want to stir them for the first 4 minutes.

Keep and eye on the soup when broiling. When you are broiling the ramekins with soup and topped with cheese the cheese will get melty and bubbly quickly so keep an eye on it so it does not burn.
