This Classic One-Pot French Onion Soup is home-y, easy to make, ready on about 35 minutes, and is truly SO delicious. It will become your new go-to for dinner during the colder months!

Ingredients

Instructions

  • In a 6 quart stock pot, melt butter.
  • Add onions and sauté until cooked down and starting to brown.
  • Add wine and cook an additional 5 minutes.
  • Add chicken stock, beef stock, and thyme.
  • Simmer for 15-20 minutes.
  • Ladle into serving bowls.
  • Top with bread slices and cheese.
  • Place under broiler until cheese is melted and edges of bread are toasted.

Notes

Substitutions:
  • If you don't have homemade chicken stock or beef stock, you can use bullion cubes or your favorite store-bough brand.
  • Dried thyme can be used in place of fresh, but you will need to decrease the amount to about 1/8 teaspoon.
  • Fontina is our favorite with this soup, but you can use any kind of white cheese like it! From Gruyère to a white cheddar.
 
Expert Tips:
  • Make sure the onions are thinly sliced! I highly recommend using a mandoline to make the slicing easier!
  • Use a white wine with a lot of citrus!
  • This soups keeps and reheats really well.
