Ingredients You’ll Need
To make a truly unforgettable Rich and Simple French Onion Soup Recipe, you don’t need a pantry full of fancy ingredients. Each element plays a critical role—from the mellow sweetness of caramelized onions to the savory depth of beef broth, plus a touch of cheesy goodness on top to seal the deal.
- 1/2 cup unsalted butter: Essential for slowly caramelizing onions without burning them while adding a creamy base to the soup.
- 2 tablespoons olive oil: Helps prevent butter from browning too quickly and adds a subtle richness to balance flavors.
- 4 cups sliced onions: The hero of the dish, these onions become sweet, tender, and packed with flavor as they cook down.
- 5 cups beef broth: Provides a hearty, savory backbone with deep umami that makes every sip satisfying.
- 2 tablespoons dry sherry: Adds a subtle fruity complexity and helps lift all the layers of flavor.
- 1 teaspoon dried thyme: Infuses the soup with a fragrant earthiness that complements the sweet onions perfectly.
- Salt and pepper to taste: Simple seasonings that bring the entire soup together with just the right balance.
- 4 slices French bread: Toasted to soak up the soup and hold the melty cheese topping without turning soggy too fast.
- 4 slices provolone cheese: Offers smooth meltability and mild nuttiness atop the soup bowls.
- 2 slices Swiss cheese, diced: Adds gooey pockets of flavor that make each bite extra cheesy and delicious.
- 1/4 cup grated Parmesan cheese: Sprinkled on top for a sharp, salty finish that crisps beautifully under the broiler.
How to Make Rich and Simple French Onion Soup Recipe
Step 1: Caramelize the Onions
Start by melting the butter along with olive oil in a large pot over medium heat. Add the sliced onions and a pinch of salt to draw out moisture. This step requires patience as you slowly cook the onions for about 30 to 40 minutes, stirring occasionally. The goal is a deep golden brown color, which creates a natural sweetness that’s the soul of the soup.
Step 2: Add Broth and Herbs
Once the onions are perfectly caramelized, pour in the beef broth and stir in the dried thyme. Bring the mixture to a gentle simmer. Let the flavors meld together for another 10 minutes so the broth absorbs all the onion’s richness. This simmering step develops that classic, hearty soup you’re craving.
Step 3: Season and Shimmy with Sherry
Season the soup with freshly cracked pepper and salt to taste. Add the dry sherry at this point and stir well. The sherry’s subtle fruitiness brightens the soup and adds a layer of complexity without overpowering the other ingredients.
Step 4: Prepare the Bread and Cheese Topping
While the soup simmers, toast the French bread slices until golden brown, then layer each slice with the provolone and diced Swiss cheeses. These toasty, cheesy croutons become the crowning glory for your soup bowls.
Step 5: Assemble and Broil
Ladle the hot soup into oven-safe bowls and float the cheesy bread on top. Sprinkle with grated Parmesan for that final touch. Place the bowls under a broiler until the cheese is bubbling and browned in spots, creating the iconic crispy, gooey topping that makes this Rich and Simple French Onion Soup Recipe unforgettable.
How to Serve Rich and Simple French Onion Soup Recipe
Garnishes
A little sprinkle of fresh thyme or finely chopped parsley adds a pop of color and a fresh aroma to your soup. For a touch of indulgence, a tiny drizzle of truffle oil on top before serving also elevates the experience dramatically.
Side Dishes
This soup is a meal in itself, but if you want to round it out, consider a crisp green salad with a light vinaigrette to cut through the richness. A plate of simple roasted vegetables or a baguette with herbed butter also pairs beautifully with the flavors in your Rich and Simple French Onion Soup Recipe.
Creative Ways to Present
Presenting your soup in rustic, individual crock bowls adds to the cozy vibe. You can also serve the cheesy toasts on a separate plate for dipping, letting guests scoop their own cheesy goodness. For parties, serve mini portions in small ramekins for a charming appetizer that promises big flavor.
Make Ahead and Storage
Storing Leftovers
Leftover soup keeps beautifully in an airtight container in the fridge for up to 3 days. Keep the cheesy bread separate until you’re ready to serve to maintain the perfect texture.
Freezing
You can freeze the soup without the cheese toppings for up to 2 months. Allow it to cool completely before transferring to freezer-safe containers. When ready to enjoy, thaw overnight in the fridge and reheat gently on the stove.
Reheating
Reheat the soup slowly over medium heat, stirring occasionally to prevent sticking or burning. If you want to enjoy the cheesy crust again, add the toasted bread and cheeses, then broil the soup just before serving.
FAQs
Can I make this soup vegetarian?
Absolutely! Substitute the beef broth with a rich vegetable broth and skip the sherry or use a non-alcoholic alternative. The onions and cheese still create a wonderfully flavorful soup.
What type of onions work best in this recipe?
Yellow onions are the classic choice due to their balance of sweetness and pungency. They caramelize beautifully and give the soup its signature flavor and appearance.
Can I use a different type of cheese?
Yes! Gruyère is a traditional option with excellent melting qualities and nutty taste. Swiss and provolone also work well if you want a milder flavor profile.
Is dry sherry necessary?
Dry sherry adds a subtle depth and brightness to the soup, but if you don’t have it, a splash of dry white wine or even apple cider vinegar can provide a similar lift.
How long does it take to caramelize the onions?
Patience is key here — it generally takes about 30 to 40 minutes over medium heat to reach that perfect deep golden color and sweet flavor binding the soup together.

- 1 pinch salt and pepper to taste
Toppings

Instructions
- Caramelize Onions: Heat the unsalted butter and olive oil in a large pot over medium heat.

Notes
- For a vegetarian version, substitute beef broth with vegetable broth and omit sherry or replace with a vegetarian cooking wine.
- Use a heavy-bottomed pot to prevent onions from burning during caramelization.
- Dry sherry enhances flavor but can be omitted if unavailable; a splash of white wine vinegar can add acidity.
- Adjust salt and pepper according to broth saltiness.
- The cheese blend can be modified to include Gruyere for a traditional touch.
- Leftovers are best reheated gently on the stovetop or in the oven to maintain texture.
