How to Make Rich and Simple French Onion Soup

Ingredients:

  • 0.5 cup unsalted butter
  • 2 tablespoons olive oil
  • 4 cups sliced onions
  • 5 cups beef broth
  • 2 tablespoons dry sherry
  • 1 teaspoon dried thyme
  • A pinch of salt and pepper to taste
  • 4 slices French bread
  • 4 slices provolone cheese
  • 2 slices Swiss cheese, diced

Directions:

  1. Gather all the ingredients.
  2. Melt the butter with olive oil in an 8-quart stock pot over medium heat. Add the sliced onions, stirring continually until they are tender and translucent. Avoid browning the onions as we want that sweet, soft texture.
  3. Pour in the beef broth, dry sherry, and thyme, and season with a pinch of salt and pepper. Let this delicious mixture simmer for about 30 minutes, allowing all those flavors to meld together beautifully. Meanwhile, preheat your oven’s broiler.
  4. Ladle the soup into oven-safe serving bowls and place one slice of French bread on top of each bowl (you can break the bread into pieces if you prefer). Then layer each slice of bread with a slice of provolone, half a slice of diced Swiss, and a tablespoon of Parmesan cheese.
  5. Place the bowls on a cookie sheet and broil in the preheated oven for 2 to 3 minutes, or until the cheese bubbles and turns golden brown.
  6. Serve hot and enjoy the smiles as each spoonful warms you from the inside out!

Serving Suggestions for Your French Onion Soup

This delightful soup shines on its own, but it can also be paired beautifully with a simple green salad or crusty whole-grain bread for a complete meal. Consider preparing a light fruit tart for dessert to round out a cozy evening.

Storing Your French Onion Soup

If you have leftovers (though that’s a rarity), let the soup cool completely before transferring it to an airtight container. You can keep it in the fridge for up to three days. When reheating, simply warm it over low heat on the stove until heated through.

Tips for Making the Best French Onion Soup

  • Be patient with your onions; caramelization is key to developing that rich flavor.
  • Feel free to experiment with different kinds of cheese to find your favorite combination.
  • For a deeper flavor, use a quality beef broth or homemade stock if you have it on hand.

Variations You Can Try

  • For a vegetarian version, swap the beef broth for vegetable broth and add your favorite herbs for extra flavor.
  • Add thinly sliced mushrooms or shallots for a unique twist on this classic dish.

FAQs

1. Can I make this soup ahead of time? Yes, you can make the soup ahead and store it in the fridge. Just add the cheese and broil it right before serving.

2. How do I avoid over-browning the onions? Stirring continuously on medium heat will help prevent them from browning too quickly.

3. Can I freeze the French onion soup? Yes! However, it’s best to freeze the soup without the cheese. Add the cheese fresh when reheating to maintain its texture.

Making this rich and simple French onion soup is not only straightforward but also a memorable culinary experience that fills your home with warmth. So, gather your ingredients and savor the journey as you create this beloved classic!
