French Onion Gnocchi Ingredients
• Discover the essential components for a delightful meal!
For the Sauce
- Olive Oil – Adds richness to the dish and prevents sticking; can substitute with canola oil if desired.
- Salted Butter – Enhances flavor while promoting caramelization; unsalted butter can be used for more controlled salt levels.
- Kosher Salt – Enhances all flavors; adjust to personal taste.
- Freshly Cracked Black Pepper – Provides seasoning; white pepper can be used for a milder flavor.
- Yellow Onion (2 pounds) – Delivers sweetness when caramelized; sweet onions could provide a mellower flavor.
- Thyme (1½ tablespoons) – Offers an earthy note; dried thyme (1 teaspoon) works in a pinch.
- Garlic (6 cloves, minced) – Adds depth and aroma; garlic powder (1½ teaspoons) may be used for convenience.
- Dry White Wine (½ cup, e.g., Sauvignon Blanc) – Enhances flavor and acidity for deglazing; substitute with vegetable broth for a non-alcoholic version.
- Dijon Mustard (2½ teaspoons) – Adds tanginess and depth; you can swap for whole grain mustard for a different texture.
- All-Purpose Flour (2½ tablespoons) – Aids in thickening the sauce; use gluten-free flour for a gluten-free option.
- Worcestershire Sauce (1 teaspoon) – Provides umami flavor; soy sauce is a good alternative.
- Bay Leaf (1 large) – Adds aromatic depth; be sure to remove before serving.
- Low Sodium Beef Stock (2½ cups) – The base for the sauce; vegetable stock can be used for a vegetarian version.
For the Gnocchi
- Gnocchi (24 ounces) – The star of the dish, traditionally potato-based; fresh homemade gnocchi can elevate the experience.
For the Cheese Topping
- Gruyère Cheese (1½ cups, freshly grated) – Provides a rich, nutty flavor that melts beautifully; Emmental cheese is a fine substitute.

Step-by-Step Instructions for French Onion Gnocchi
Step 1: Heat the Base
In an 11-inch skillet, combine 2 tablespoons of olive oil and 2 tablespoons of salted butter over medium heat. Allow the butter to melt completely, creating a rich base. Once melted, add 2 pounds of thinly sliced yellow onions to the skillet, ensuring they are evenly distributed for optimal caramelization.
Step 2: Caramelize the Onions
Stir the onions every few minutes, keeping the heat low to encourage even caramelization. This process will take about 45–60 minutes, during which the onions will turn a deep golden brown. If they start to stick, add 1½ teaspoons of water occasionally, stirring to release any flavorful bits from the skillet bottom.
Step 3: Add Aromatics
In the last 5 minutes of caramelizing the onions, stir in 1½ tablespoons of fresh thyme and 6 cloves of minced garlic. Continue cooking until the garlic is fragrant, about 1–2 minutes. This will enhance the depth of flavor in your French Onion Gnocchi, making it truly delightful.
Step 4: Deglaze the Skillet
Pour in ½ cup of dry white wine and allow it to reduce for 3–4 minutes, scraping any bits off the bottom of the skillet. This step adds complexity to the sauce. Once reduced, sprinkle in 2½ tablespoons of all-purpose flour, stirring well to eliminate lumps and create a luscious base for your sauce.
Step 5: Season and Simmer
Mix in 2½ teaspoons of Dijon mustard and 1 teaspoon of Worcestershire sauce for added flavor. Gradually pour in 2½ cups of low sodium beef stock, adding a bay leaf for aromatic depth. Bring the mixture to a boil, then reduce the heat to a simmer for 6–7 minutes, until the sauce thickens slightly.
Step 6: Prepare the Gnocchi
While the sauce simmers, bring a medium pot of salted water to a boil. Add 24 ounces of gnocchi and cook until they float, indicating that they are done—this should take about 2–3 minutes. Drain the gnocchi and gently fold them into the sauce, ensuring they are well coated.
Step 7: Add Cheese Topping
Spread 1½ cups of freshly grated Gruyère cheese and ½ cup of freshly grated Parmesan cheese evenly over the gnocchi in the skillet. Preheat your broiler, then place the skillet under the broiler for 3–5 minutes, watching carefully until the cheese is melted and bubbling, creating a beautiful golden crust.
Step 8: Garnish and Serve
Remove the skillet from the oven and let it sit for a minute. Garnish with additional thyme leaves for a fresh touch. Serve your comforting French Onion Gnocchi immediately, enjoying it with crusty bread or a side salad for a delightful meal.
How to Store and Freeze French Onion Gnocchi
Fridge: Store any leftover French Onion Gnocchi in an airtight container for up to 3 days. This will help maintain its flavors and texture.
Freezer: For longer storage, freeze the gnocchi in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 3 months.
Reheating: When ready to enjoy, reheat the gnocchi in the oven at 350°F (175°C) for about 20 minutes or until heated through. This will restore the creamy sauce and melted cheese texture beautifully.
Expert Tips for French Onion Gnocchi
-
Slow and Steady: Caramelizing onions takes time—allow them 45-60 minutes over low heat for that perfect sweetness. Rushing results in burnt bits and less flavor.
-
Scraping is Key: Regularly scrape the bottom of your skillet while deglazing; this helps incorporate flavorful bits into the sauce, enhancing your French Onion Gnocchi.
-
Cheese Monitoring: Keep a close eye while broiling the cheese; a literal minute can turn it from golden-brown perfection to burnt.
-
Adjusting Thickness: If your sauce seems too thick, add a splash of beef stock or water to reach your desired consistency without sacrificing flavor.
-
Custom Flavor: Experiment with different cheese blends or herbs—adding a hint of rosemary or a dash of smoked cheddar can elevate your French Onion Gnocchi to new heights!

French Onion Gnocchi Recipe FAQs
How do I choose the right onions for this recipe?
Absolutely! For the best flavor, choose yellow onions as they caramelize beautifully and provide that rich sweetness essential to this dish. Look for onions that are firm without dark spots or blemishes, as these will lead to better caramelization. If you can’t find yellow onions, sweet onions are also a great substitution.

How should I store leftovers?
To enjoy your French Onion Gnocchi beyond the dinner table, store leftovers in an airtight container in the fridge for up to 3 days. Make sure to cover them well to prevent the sauce from drying out. When reheating, I suggest using the oven at 350°F for about 20 minutes to bring back that creamy texture.
Can I freeze French Onion Gnocchi?
Very! To freeze your French Onion Gnocchi, first spread it in a single layer on a baking sheet and freeze until solid. This prevents the gnocchi from sticking together. Once frozen, transfer them to a freezer-safe bag. You can store them this way for up to 3 months. When ready to enjoy, cook from frozen in boiling water until they float, then mix them into your sauce.
What if my onions are burning while caramelizing?
If your onions start to burn, don’t panic! Lower the heat immediately and add 1-2 teaspoons of water to the skillet to deglaze and prevent them from sticking. Give them a good stir to lift any brown bits off the bottom, which are packed with flavor. The goal is to achieve a deep brown, sweet flavor, so patience is key—this should take about 45-60 minutes.
Are there any dietary considerations I should keep in mind?
Absolutely! If you need a vegetarian option, simply replace beef stock with vegetable stock. Also, if you’re concerned about gluten, use a gluten-free flour for thickening the sauce and ensure that your gnocchi are gluten-free as well. Always check labels to avoid allergens, especially if you’re serving this dish to guests with dietary restrictions.
Can I make this dish in advance?
Yes! You can prepare the sauce ahead of time and store it in the fridge for up to 3 days. When you’re ready to serve, simply cook the gnocchi fresh and combine them with the prepared sauce. This way, you’ll save time while still serving a delicious, homemade meal.
