Ingredients You’ll Need
When it comes to this French Onion Gnocchi Recipe, the ingredients really come together to build deep flavor and creamy texture. Using yellow onions and a good-quality Gruyère will take it to the next level — plus, I always rely on a splash of Sauvignon Blanc to add brightness.
- Olive oil: Adds a fruity base fat for sautéing onions with butter.
- Salted butter: I use a good butter here to enrich the caramelization process.
- Kosher salt: Because it seasons more evenly than table salt.
- Freshly cracked black pepper: For a subtle kick that balances the sweetness of onions.
- Store-bought gnocchi: Convenient and pillowy—look for fresh or high-quality frozen.
- Yellow onion: The star of this dish, slow-cooked until golden and sweet.
- Thyme: Adds an herby layer that pairs beautifully with caramelized onions.
- Garlic: Minced and added near the end for aromatic fragrance.
- Dry white wine (Sauvignon Blanc): Helps deglaze the pan and adds bright acidity.
- Dijon mustard: Gives a subtle tang that cuts through richness.
- All-purpose flour: Helps thicken the onion sauce for a luscious consistency.
- Worcestershire sauce: Brings umami depth to the sauce.
- Bay leaf: Infuses a subtle savory aroma while simmering.
- Beef stock (low sodium): Base for the sauce, enriching the flavor without overpowering.
- Gruyère cheese: Creamy melting cheese that’s nutty and perfect for broiling on top.
- Parmesan cheese: Adds sharpness and an extra cheesy kick as a finishing touch.
Variations
I love that this French Onion Gnocchi Recipe can be customized to suit whatever you’re craving or have on hand. Feel free to play with the cheeses, swap in herbs, or even make it vegetarian-friendly.
- Vegetarian version: Simply replace beef stock with vegetable broth, and you’ll still get that rich flavor.
- Cheese swaps: Try fontina or mozzarella if you want a milder melt or use aged cheddar for sharper flavor.
- Herbs: I sometimes add rosemary or sage along with thyme for an earthier note.
- Spicy twist: A pinch of red pepper flakes stirred in with the garlic gives a subtle heat that my family loves.
How to Make French Onion Gnocchi Recipe
Step 1: Slow-Caramelize the Onions
This is the heart of the recipe and where patience really pays off. Over medium heat, melt your butter and olive oil in a large skillet, then add the sliced yellow onions. Stir every few minutes—it’s crucial not to rush this process. The onions need about 45-60 minutes to reach that perfect deep golden brown without burning. If the mixture starts to dry out, gently add a teaspoon or two of water to keep it soft and sticky rather than crispy. This slow caramelization unlocks the natural sugars for incredible sweetness and depth.
Step 2: Build Flavor With Herbs, Garlic, and Wine
Once the onions are beautifully caramelized, stir in fresh thyme and minced garlic. Cook just a couple of minutes to release their fragrance, then pour in the white wine. Let this simmer and reduce by about half—watch as it intensifies the flavor and helps deglaze the pan, lifting those yummy browned bits off the bottom.
Step 3: Thicken and Season Your Sauce
Sprinkle in the flour and cook it for a minute or two to get rid of the raw taste, stirring constantly until the sauce thickens slightly. Then whisk in Dijon mustard and Worcestershire sauce—this combo adds tang and umami complexity. Pour in the beef stock along with a bay leaf, scraping the bottom of the pan to incorporate all those browned flavors. Bring it to a boil, then lower the heat and simmer until it thickens a bit more, about 6-7 minutes. Taste and season with kosher salt and freshly cracked black pepper to your liking.
Step 4: Cook the Gnocchi and Combine
While the sauce simmers, bring a pot of salted water to a boil. Drop in the gnocchi and watch patiently—they’re done as soon as they float to the top, which usually takes just a couple of minutes. Drain them well and toss immediately into your onion sauce, stirring gently so each gnocchi is coated in that luscious caramelized onion goodness.
Step 5: Cheese It and Broil
Transfer everything to an oven-safe dish if your pan isn’t broiler-safe. Sprinkle a generous layer of freshly grated Parmesan followed by the nutty Gruyère. Pop it under the broiler for 3-5 minutes, keeping a close eye until the cheese bubbles and browns beautifully. This cheesy crust is the ultimate finish—you’re really going to love it!
Step 6: Garnish and Serve
Top with a few fresh thyme leaves for a pop of color and herby fragrance. Serve it hot, preferably with some crusty bread or alongside a fresh salad, and enjoy the magic you just created!
Pro Tips for Making French Onion Gnocchi Recipe
- Patience is key: Don’t rush caramelizing onions; slow cooking brings out their natural sweetness and complexity.
- Keep the pan stirred: Stir every few minutes during caramelization to prevent burning but still allow deep browning.
- Use fresh cheeses: Freshly grated Parmesan and Gruyère melt better and add richer flavor than pre-grated options.
- Watch the broiler closely: The cheese melts quickly and can burn if unattended—stay nearby!
How to Serve French Onion Gnocchi Recipe
Garnishes
I usually finish this dish with a sprinkle of fresh thyme leaves because their subtle earthiness pairs beautifully with the rich onion sauce and melty cheese. Sometimes I add a little extra cracked black pepper on top for a gentle bite. You could even sprinkle a few finely chopped chives for a mild allium freshness that complements the flavors nicely.
Side Dishes
For sides, I love serving this with a crisp green salad tossed in a light vinaigrette to balance the richness of the gnocchi. Crusty bread is a must-have for mopping up every last bit of sauce. And if you want to keep the comfort theme going, creamy mashed potatoes make a lovely pairing that will have your family going crazy.
Creative Ways to Present
For a special occasion, I like to bake this dish in individual ramekins or mini cast iron skillets. The personal-sized portions look charming and are perfect for entertaining. You can also top with caramelized pearl onions or crispy shallots for an extra fancy touch. Trust me, your guests will be impressed by the presentation and the incredible flavors.
Make Ahead and Storage
Storing Leftovers
Leftovers store really well covered tightly in the fridge for up to 3 days. I usually transfer them into an airtight container to keep the gnocchi from drying out. When reheating, you might want to add a splash of beef stock or water to loosen up the sauce, because it thickens as it sits.
Freezing
I’ve frozen this French Onion Gnocchi Recipe a few times without issue. Just allow it to cool completely, then place into a freezer-safe container or bag. Thaw overnight in the fridge before reheating gently on the stovetop or in the oven. The texture might soften a bit after freezing but flavors remain delicious.
Reheating
To reheat, I prefer warming it slowly over low heat in a skillet, stirring gently to retain sauciness and prevent gnocchi from sticking. Alternatively, with leftovers in an oven-safe dish, cover with foil and bake at 350°F (175°C) until heated through, then remove the foil and broil briefly to refresh the cheese topping.
FAQs
-
Can I make French Onion Gnocchi Recipe ahead of time?
Yes! You can caramelize the onions in advance and prepare the sauce. Store it separately in the fridge and cook the gnocchi just before serving. You can also assemble the whole dish and refrigerate it before broiling the cheese topping right before serving for fresh bubbly cheese.
-
What type of gnocchi works best for this recipe?
I recommend using fresh or high-quality store-bought gnocchi for the best texture — they cook quickly and soak up the sauce beautifully. Frozen gnocchi works too, but avoid dry-packed varieties as they can be dense and chewy.
-
Can I substitute the beef stock for a vegetarian option?
Absolutely! Use a rich vegetable broth instead of beef stock to keep the dish vegetarian-friendly. You might want to add a splash of soy sauce or mushroom broth to boost the umami flavor that beef stock provides.
-
How long does it take to caramelize the onions?
Plan for about 45 to 60 minutes over medium heat. The key is to cook them slowly, stirring occasionally, so they become deeply golden and sweet without burning. This step is essential for authentic flavor.

Ingredients
For the Gnocchi and Sauce
- 1½ tablespoons olive oil
- 2½ tablespoons salted butter
- Kosher salt, to taste
- Freshly cracked black pepper, to taste
- 24 ounces store-bought gnocchi
- 2 pounds yellow onion, halved and thinly sliced
- 1½ tablespoons thyme, finely chopped
- 6 cloves garlic, minced
- ½ cup dry white wine (Sauvignon Blanc recommended)
- 2½ teaspoons dijon mustard
- 2½ tablespoons all-purpose flour
- 1 teaspoon worcestershire sauce
- 1 large bay leaf
- 2½ cups beef stock, low sodium
For the Cheese Topping
- 1½ cups gruyere cheese, freshly grated
- ½ cup parmesan cheese, freshly grated
Instructions
- Caramelize the Onions: Over medium heat, heat the olive oil and butter together. Once the butter melts, add the sliced onions. Stir every few minutes to avoid burning, cooking slowly for 45-60 minutes. The onions should turn a deep brown color without rushing or browning too quickly. If the onions begin to dry out, add 1½ teaspoons of water at a time and stir to maintain moisture.
- Add Thyme and Garlic: When the onions are deeply caramelized, stir in the finely chopped thyme and minced garlic. Cook for about two minutes until fragrant.
- Deglaze with Wine: Pour in the dry white wine and cook until the liquid reduces by about half, roughly 3-4 minutes. This adds depth and acidity to the sauce.
- Thicken the Mixture: Stir in the all-purpose flour. Cook for 1-2 minutes until the mixture slightly thickens. Then add the dijon mustard and worcestershire sauce, stirring well to combine evenly with the onion mixture.
- Add Beef Stock and Bay Leaf: Pour in the beef stock and add the bay leaf. Scrape the bottom of the pan to lift and incorporate any browned bits. Bring the sauce to a boil, then lower to a simmer and cook for 6-7 minutes until it slightly reduces and thickens. Season with kosher salt and freshly cracked black pepper to taste.
- Cook the Gnocchi: Around 40 minutes into the onion cooking, bring a medium pot of salted water to a boil. Add the gnocchi to the boiling water and cook until they float to the surface, about 2-3 minutes. Drain the gnocchi well.
- Combine Gnocchi and Sauce: Transfer the drained gnocchi to the skillet with the onion sauce. Stir gently to combine the gnocchi evenly with the sauce.
- Add Cheese Toppings: Sprinkle the grated parmesan cheese evenly over the gnocchi and then layer the grated gruyere on top.
- Broil Cheese: Place the skillet or oven-safe dish under the broiler for 3-5 minutes, or until the cheese is fully melted, bubbly, and slightly golden brown on top.
- Serve and Garnish: Garnish the dish with additional fresh thyme. Serve immediately alongside crusty bread, mashed potatoes, or salad for a complete meal. Enjoy the comforting flavors of this elegant French Onion Gnocchi dish!
