Ingredients You’ll Need

To make the best French onion soup, you’ll need a handful of pantry staples and fresh ingredients:

• Onions – The star of the dish! Yellow onions are traditional, but you can use white or red onions for a twist.
• Beef stock – Forms the rich, savory base (vegetable stock can be used for a vegetarian option).
• Butter – Essential for caramelizing the onions.
• Flour – Helps thicken the soup; use gluten-free flour if needed.
• Dry white wine – Adds depth and deglazes the pan.
• Seasonings – Worcestershire sauce, fresh thyme, garlic, and bay leaves enhance the flavor.
• French bread – Toasted slices to soak up the soup.
• Swiss cheese – The finishing touch, though Gruyère, mozzarella, provolone, or gouda can be used.

How to Make French Onion Soup

This easy French onion soup recipe may taste complex, but the process is quite simple:

1. Caramelize the Onions – Melt butter in a pot, add thinly sliced onions, and cook until golden brown.
2. Add Garlic and Flour – Stir in garlic and flour to form a thick base.
3. Deglaze the Pan – Pour in white wine to lift flavorful bits from the pan.
4. Simmer the Soup – Add beef stock, Worcestershire sauce, thyme, and a bay leaf, then let it simmer.
5. Toast the Bread – Slice a French baguette and toast until crispy.
6. Assemble and Broil – Ladle soup into oven-safe bowls, top with bread and cheese, then broil until the cheese is bubbly and golden.

Expert Tips for the Perfect French Onion Soup

• Don’t Skimp on Wine – If brown bits stick to the pan, add extra wine to deglaze—it won’t overpower the soup.
• Gluten-Free & Vegetarian Options – Use vegetable stock instead of beef and swap in gluten-free flour and bread.
• Cheese Variations – While Swiss is commonly used, Gruyère is traditional. Try gouda, mozzarella, or provolone for a different flavor.
• No Bread? – Croutons make a great substitute!
• Perfect Broiling – Use a broiler rather than an oven to get that classic, golden cheese crust.
