The Bistro Classics: The Essential Ingredients
This iconic dish uses a handful of high-quality ingredients to create its signature rich and savory flavor.
- The Onions (The Heart of the Soup!):
- For the best, sweetest, and most complex flavor, it is highly recommended to use classic yellow onions. The number one secret to a truly great French Onion Soup is to take the time to caramelize them slowly. This is a low-and-slow process that coaxes out their natural sugars and transforms them from sharp and pungent to deeply sweet, jammy, and a beautiful amber color.
- The “Dumplings” (Gnocchi!):
- Potato Gnocchi: This is the brilliant and easy twist that makes this soup a complete and hearty meal! Using a 16-ounce package of your favorite brand of store-bought, shelf-stable potato gnocchi provides the perfect, tender, and pillowy bite that beautifully soaks up the savory broth.
- The Broth:
- Beef Broth: For the most authentic, rich, and deeply savory flavor, a high-quality beef broth is the classic and highly recommended choice.
- The Cheese (Gruyère is a Must!):
- Gruyère Cheese: For that classic, authentic, and unforgettable cheesy topping, there is no substitute for a good quality Gruyère cheese. This classic Swiss alpine cheese has a wonderful, nutty, slightly sweet, and complex flavor, and it melts into the most perfect, gooey, and beautifully browned blanket.
Step-by-Step to the Best French Onion Gnocchi Soup
This elegant, one-pot meal is incredibly simple to prepare.
Step 1: The Art of Perfectly Caramelized Onions
In a large pot or Dutch oven, melt your 3 tablespoons of butter over a medium-low heat. Add your 4 thinly sliced onions and a generous pinch of salt.
Cook, stirring occasionally, for 30 to 40 minutes. Be patient! This low-and-slow process is the key that will transform the onions from sharp and white to deeply sweet, jammy, and a beautiful, rich amber-brown color.
Part 2: Build the Soup Base and Cook the Gnocchi
Step 1: Add 2 cloves of minced garlic and 1 teaspoon of fresh thyme leaves to the pot with the caramelized onions. Cook for 1 more minute, until the garlic is very fragrant.
Step 2: Pour in 1/2 cup of dry white wine to deglaze the pot. Use your spoon to scrape up all the delicious, flavorful browned bits from the bottom of the pot.
Step 3: Pour in your 4 cups of beef broth and bring the mixture to a simmer.
Step 4: Stir in your 16-ounce package of gnocchi and cook for about 3 minutes, until the gnocchi are plump and have floated to the surface of the broth.
Part 3: The Final, Cheesy Finish (Under the Broiler!)
Step 1 (The Most Important Step!): Preheat your oven’s broiler. Step 2: Ladle the hot soup into individual, oven-safe bowls or crocks. Step 3: Top each bowl with a very generous handful of your 1 cup of shredded Gruyère cheese. Step 4: Carefully place the bowls on a baking sheet and put them under the broiler for just 2 to 3 minutes. Watch them like a hawk! You want the cheese to be completely melted, bubbly, and a beautiful, deep golden brown with a few slightly charred spots.
Serve the soup immediately, being careful as the bowls will be very hot.
French Onion Gnocchi Soup (The Ultimate Comfort Food!)
A comforting and easy soup that combines the classic, rich flavors of French Onion Soup with soft, pillowy potato gnocchi. This one-pot recipe features thinly sliced onions that are slowly sautéed in butter until deeply sweet and caramelized. A savory beef broth is then added to the pot, and the gnocchi are cooked directly in the flavorful broth. The soup is served hot in bowls with a generous topping of shredded Gruyère cheese that melts into the rich broth.
Ingredients
- 4 onions, thinly sliced
- 3 tbsp butter
- 4 cups beef broth
- 1 package (16 oz) gnocchi
- 1 cup shredded Gruyere cheese
- Salt and pepper to taste
Instructions
- In a large pot or Dutch oven, melt the butter over medium-low heat. Add the thinly sliced onions and a pinch of salt.
- Cook slowly, stirring occasionally, for 20-30 minutes, until the onions are deeply caramelized, soft, and sweet.
- Add the beef broth to the pot, scraping up any browned bits from the bottom. Bring the soup to a simmer.
- Stir in the gnocchi and cook for about 3 minutes, or until they float to the surface and are tender.
- Season the soup with salt and pepper to taste.
- Ladle the hot soup into bowls and serve immediately, topped with a generous sprinkle of shredded Gruyere cheese.
Notes
- The key to this soup’s deep, rich flavor is taking the time to properly caramelize the onions until they are soft and golden brown. This process should not be rushed.
- Cooking the gnocchi directly in the broth is a quick and easy method that also helps to slightly thicken the soup.
- For a more traditional presentation, you can ladle the soup into oven-safe bowls, top with a slice of toasted bread and the cheese, and place it under the broiler until the cheese is melted and bubbly.
What to Serve With Your French Onion Gnocchi Soup
This beautiful and rich soup is a fantastic, all-in-one meal that is incredibly hearty and satisfying. If you’d like to round it out, here are a few simple and classic pairings:
- A Simple Green Salad: A crisp green salad, especially one with a bright and zesty mustard vinaigrette, is the perfect, fresh counterpoint to the rich, cheesy soup.
- A Glass of Wine: A glass of a crisp white wine (like the one you used in the soup!) or a light-bodied red wine is a wonderful accompaniment for the adults.
Storage and Make-Ahead Tips
- Make-Ahead: For a super-fast and impressive meal, you can get a head start by preparing the entire soup base (the caramelized onions and the broth) up to 3 days in advance. Store it in an airtight container in the refrigerator. When you are ready to eat, you can simply reheat the soup base on the stovetop, cook the gnocchi, and then proceed with the final broiling step.
- Storage: Store any leftover soup (without the broiled cheese topping) in an airtight container in the refrigerator for up to 4 days.

Creative Recipe Variations
- Make it Vegetarian: For a delicious and hearty vegetarian version, you can simply substitute the beef broth with an equal amount of a high-quality, savory mushroom or a dark vegetable broth.
- Add a Classic Crouton: For the full, authentic French Onion Soup experience, you can float a single, thick slice of a toasted baguette on top of the soup in each bowl before you add the Gruyère cheese and broil it.
- Use a Different Cheese: If you can’t find Gruyère, a classic Swiss cheese, a nutty Comté, or even a simple Provolone would also be delicious and would melt beautifully.

Frequently Asked Questions (FAQs)
Q1: What is the absolute, number one secret to truly deep, sweet, and flavorful caramelized onions?
The secret is time and patience. You must cook your onions low and slow over a medium-low heat. This gentle heat is the key that coaxes out the natural sugars in the onions and allows them to slowly caramelize, which is what creates that signature, deep, jammy, and incredibly sweet flavor. Rushing the process over a high heat will just burn the onions.
Q2: What is the best kind of cheese to use for French Onion Soup?
For the most authentic and delicious flavor, a classic, nutty, and slightly sweet Gruyère cheese is the number one choice. It has a wonderful, complex flavor and a superior melting quality that creates the most perfect, gooey, and beautifully browned cheese blanket.
Q3: Can I make this soup ahead of time?
Yes, this is a perfect make-ahead soup! You can prepare the entire soup base, with the caramelized onions and the broth, and store it in the refrigerator for up to 3 days. When you are ready to eat, you can simply reheat the soup, cook the fresh gnocchi in it, and then do the final, quick broiling step with the cheese.
Q4: Can I freeze this soup?
Yes, the soup base (without the gnocchi or the cheese topping) freezes beautifully! Let it cool completely, and then you can store it in a freezer-safe container for up to 3 months. When you are ready to eat, you can thaw the soup base, bring it to a simmer, and then cook your fresh gnocchi in it.
Q5: What is gnocchi?
Gnocchi are a type of classic, Italian “dumpling.” The most common variety, and the one that is perfect for this recipe, is a potato gnocchi, which is made from a simple dough of cooked, mashed potatoes and flour. They have a wonderfully soft, tender, and pillowy texture when they are cooked.
