How to Make French Onion Gnocchi Soup with Gruyere

Step 1: Caramelize the onions

Start by thinly slicing your onions. Heat butter and olive oil in a large pot over medium-low heat, then slowly cook the onions, stirring occasionally, until they turn deep golden brown and sweet, about 40-50 minutes. This slow caramelization builds the deep, rich flavor foundation of the soup.

Step 2: Add garlic and deglaze

Stir in minced garlic and cook for a minute until fragrant. Pour in dry white wine or sherry to deglaze the pot, scraping up any browned bits stuck to the bottom. Let the wine reduce by half to concentrate the flavor.

Step 3: Pour in broth and simmer

Add beef or vegetable broth along with fresh thyme. Bring the soup to a gentle boil, then reduce the heat and let it simmer for about 20 minutes. Season with salt and pepper to taste.

Step 4: Cook the gnocchi

Meanwhile, cook gnocchi separately according to package instructions until they float, indicating they’re done. Drain and gently fold them into the soup just before serving.

Step 5: Assemble and melt Gruyere

Ladle the soup into oven-safe bowls, top with toasted baguette slices or croutons, and generously pile grated Gruyere on top. Place the bowls under a broiler until the cheese is melted, bubbly, and golden brown.

Pro Tips for Making French Onion Gnocchi Soup with Gruyere

• Be patient caramelizing: Low and slow cooking ensures maximum onion sweetness and prevents bitterness.
• Use good-quality broth: A flavorful broth makes all the difference in the soup’s depth.
• Don’t skip the wine: It adds acidity and rounds out the flavors beautifully.
• Toast your bread: Lightly toasting the baguette slices helps them hold up under the cheese without getting soggy.
• Serve immediately: The melty Gruyere is best enjoyed fresh right out of the oven for optimal texture and taste.
• Fresh thyme is key: Adds a fragrant, herbal brightness that balances the richness.

How to Serve French Onion Gnocchi Soup with Gruyere

Garnishes

Fresh herbs like thyme or parsley sprinkled on top add color and a fresh note. A drizzle of truffle oil or a few grinds of black pepper can also elevate the flavor layers perfectly.

Side Dishes

This soup pairs wonderfully with a simple mixed greens salad dressed in vinaigrette, roasted vegetables, or a crisp apple slaw for balancing richness with freshness. Crusty bread or a warm baguette is always a crowd-pleaser for dipping.

Creative Ways to Present

Serve in rustic ramekins or mini cast iron skillets for individual portions that look cozy and inviting. For a dinner party, consider setting out a “build your own” soup bar with various cheeses, garnishes, and breads for guests to customize their bowls.

Make Ahead and Storage

Storing Leftovers

French Onion Gnocchi Soup with Gruyere is best stored without the cheese topping in an airtight container in the refrigerator. It will keep fresh for up to 3 days.

Freezing

While the soup base freezes well, avoid freezing with cooked gnocchi or melted Gruyere, as they may become mushy or lose texture after thawing. Freeze the broth and onions separately if possible.

Reheating

Reheat the soup gently on the stovetop over low heat, stirring occasionally. Add fresh gnocchi and top with Gruyere, then broil just before serving to restore the melty cheese goodness.

FAQs

Can I make French Onion Gnocchi Soup with Gruyere vegetarian?

Absolutely! Simply substitute beef broth with a rich vegetable broth and ensure your wine is vegetarian-friendly. The flavor will still be rich and delicious.

Is it better to use homemade or store-bought gnocchi?

Both options work well; store-bought gnocchi is convenient and cooks quickly, while homemade gnocchi offers a fresh, tender texture if you have time to make it.

Can I use a different cheese instead of Gruyere?

Yes, cheeses like fontina, mozzarella, or sharp white cheddar make great alternatives with slightly different flavors and melt qualities.

How do I prevent my onions from burning during caramelization?

Keep the heat low and stir frequently. If onions start to stick or burn, add a splash of water or broth to loosen the pan.

What’s the best way to reheat leftover soup with cheese topping?

Remove the cheese topping before storing. When reheating, warm the soup on the stove and add fresh cheese on top, then broil until bubbly and golden right before serving.
