Ingredients
Here’s everything you’ll need to create this indulgent French Onion Gnocchi:
- 1½ tablespoons olive oil
- 2½ tablespoons salted butter
- Kosher salt (to taste)
- Freshly cracked black pepper (to taste)
- 24 ounces gnocchi (store bought)
- 2 pounds yellow onion (halved and thinly sliced)
- 1½ tablespoons thyme (finely chopped)
- 6 cloves garlic (minced)
- ½ cup dry white wine (I use Sauvignon Blanc)
- 2½ teaspoons dijon mustard
- 2½ tablespoons all-purpose flour
- 1 teaspoon worcestershire sauce
- 1 large bay leaf
- 2½ cups beef stock (low sodium)
- 1½ cups gruyere cheese (freshly grated)
- ½ cup parmesan cheese (freshly grated)
How to Make French Onion Gnocchi
Step 1: Caramelize the Onions
Over medium heat, add the olive oil and butter. Once the butter melts, add the onions and stir every few minutes. Do not rush this process; caramelizing onions takes about 45-60 minutes. As you cook, ensure they brown slowly. If the mixture dries out, add water by the teaspoon as needed.
Step 2: Add Thyme and Garlic
Once the onions are deep brown in color, stir in the thyme and garlic. Cook for two minutes or until fragrant.
Step 3: Deglaze with Wine
Stir in the white wine and let it reduce by half over about 3-4 minutes.
Step 4: Thicken with Flour
Add flour to the mixture and cook until slightly thickened, about 1-2 minutes. Then incorporate dijon mustard and Worcestershire sauce.
Step 5: Create the Sauce Base
Add beef stock along with a bay leaf. Scrape any brown bits from the skillet’s bottom to enhance flavor. Bring to a boil, then lower to a simmer for about 6-7 minutes. Season with salt and pepper before moving on.
Step 6: Cook Gnocchi
While waiting for your sauce to thicken, add gnocchi to boiling salted water. Once they float to the top, drain well and transfer them into your sauce.
Step 7: Cheese It Up
Top your dish first with grated parmesan cheese followed by gruyère cheese. Transfer to an oven-safe dish and broil for about 3-5 minutes until melted.
Step 8: Serve
Garnish with thyme and serve immediately alongside crusty bread, mashed potatoes, or salad. Enjoy your delicious French Onion Gnocchi!

- Not Seasoning Properly: Failing to taste and adjust seasoning can result in bland gnocchi. Always season with kosher salt and freshly cracked black pepper throughout cooking.
- Overcooking Gnocchi: Cooking gnocchi for too long can make them mushy. They are ready when they float to the top; this usually takes just a couple of minutes.
