Equipment

  • 1 Large Pot For sautéing onions and simmering the soup.
  • 1 Oven-safe bowls For serving the soup.

Ingredients
  

Onions

  • 4 large Onions The star of the soup; sweet, caramelized onions create depth of flavor.
  • 2 tablespoons Butter Adds richness and helps in caramelizing the onions to perfection.
  • 2 tablespoons Olive Oil A great alternative to butter for sautéing the onions; adds a nice flavor.

Broth

  • 4 cups Low-sodium vegetable broth Provides a savory base; opt for low-sodium for better control over saltiness.
  • 1 teaspoon Sugar Helps in caramelizing the onions.
  • 1 teaspoon Salt For seasoning.
  • 1 teaspoon Dried thyme Adds an aromatic touch to the soup.

Bread

  • 4 slices Crusty bread Ideal for topping the soup; choose a crusty variety for the best texture.
  • 1 cup Cheese Gruyère or Swiss cheese melts beautifully on top, adding creaminess.

Instructions
 

Step 1: Gather Your Ingredients

  • Collect 4 large onions, 4 cups of low-sodium vegetable broth, 2 tablespoons of olive oil, 2 tablespoons of unsalted butter, 1 teaspoon of sugar, 1 teaspoon of salt, 1 teaspoon of dried thyme, and 4 slices of crusty bread. Don’t forget the cheese—gruyère or mozzarella works wonders!

Step 2: Slice the Onions

  • Peel and slice the onions thinly. Aim for uniform slices to ensure even cooking. Grab a tissue if you need to; those onions can be tear-jerkers!

Step 3: Sauté the Onions

  • In a large pot, heat the olive oil and butter over medium heat. Add the sliced onions, sugar, and salt. Stir them gently, letting them soften and caramelize for about 20-25 minutes. Patience is key here!

Step 4: Add the Broth and Seasonings

  • Once the onions are beautifully caramelized, pour in the vegetable broth. Add the dried thyme and stir well. Bring the mixture to a gentle simmer and let it cook for another 15 minutes. Your kitchen will smell heavenly!

Step 5: Prepare the Bread

  • While the soup simmers, toast the slices of bread until golden brown. You want them crispy enough to hold up in the soup without getting soggy.

Step 6: Assemble the Soup

  • Once the soup is ready, ladle it into oven-safe bowls. Place a slice of toasted bread on top of each bowl and generously sprinkle with cheese. Don’t be shy—more cheese equals more happiness!

Step 7: Broil to Perfection

  • Place the bowls under the broiler for about 2-3 minutes, or until the cheese is bubbly and golden. Keep a close eye on them; you don’t want to burn that cheesy goodness!

Step 8: Serve and Enjoy!

  • Carefully remove the bowls from the oven (they’ll be hot!). Let them cool for a minute, then dig in! Enjoy your homemade French onion soup with a smile and maybe a little dance!

FAQs

What type of onions are best for French onion soup?

Yellow onions are the classic choice for French onion soup due to their sweetness and depth of flavor when caramelized. However, you can also mix in some sweet onions like Vidalia for an extra layer of sweetness. Just remember to slice them thinly for even cooking!

Can I make French onion soup without cheese?

Absolutely! While cheese adds a creamy texture and rich flavor, you can enjoy a delicious soup without it. Consider adding a sprinkle of nutritional yeast for a cheesy flavor or simply enjoy the savory broth and caramelized onions on their own.

What can I use instead of beef broth?

If you prefer not to use beef broth, vegetable broth is a great substitute. You can enhance the flavor by adding a splash of soy sauce or miso paste for umami richness. This will give your soup a hearty taste without any meat products.

How can I make my soup thicker?

To thicken your French onion soup, you can add a small amount of cornstarch mixed with cold water or a roux made from flour and butter. Another option is to let the soup simmer longer to reduce the liquid, concentrating the flavors and creating a thicker consistency.
