Step‑by‑Step Instructions for French Onion Gnocchi

Step 1: Sauté the Aromatics
In an 11-inch skillet, melt 2 tablespoons of salted butter with 2 tablespoons of olive oil over medium heat. Once the butter is melted and bubbling, add 2 pounds of sliced yellow onions. Sauté the onions gently, stirring occasionally, for about 45 to 60 minutes until they reach a deep brown and caramelized color, releasing a sweet aroma that fills your kitchen.

Step 2: Monitor and Adjust Onions
As the onions cook, keep an eye on their moisture level. If they dry out, add water in 1½ teaspoon increments to keep them moist and prevent burning. This process is crucial in achieving the perfect caramelization for your French Onion Gnocchi, intensifying the flavor of each bite.

Step 3: Prep for the Sauce
About 40 minutes into the caramelization process, bring a medium saucepan of salted water to a boil over high heat. This will be used for cooking the gnocchi later, ensuring they are tossed into the rich, creamy sauce at just the right moment. Preparing this in advance makes for a smoother cooking experience.

Step 4: Add Herbs and Garlic
Once the onions are beautifully caramelized, sprinkle in 1½ tablespoons of finely chopped thyme and 6 minced garlic cloves. Sauté for an additional 2 minutes, letting the garlic’s aroma bloom alongside the onions. This addition enhances the depth of flavor in your sauce, setting the foundation for your irresistible dish.

Step 5: Deglaze with Wine
Pour in ½ cup of dry white wine, scraping the bottom of the skillet with a wooden spoon to deglaze and lift those flavorful brown bits. Allow the wine to reduce by half, which should take about 3 to 4 minutes. This step infuses your French Onion Gnocchi with an extra layer of complexity and richness.

Step 6: Thicken the Sauce
Stir in 2½ tablespoons of all-purpose flour, cooking it briefly for about 1 minute until it’s fully incorporated. This will help thicken the sauce and create a creamy texture that clings to the gnocchi. Then mix in 2½ teaspoons of Dijon mustard and 1 teaspoon of Worcestershire sauce for added depth.

Step 7: Pour in the Stock
Gradually incorporate 2½ cups of low sodium beef stock along with 1 large bay leaf, stirring continuously to combine. Scrape any remaining brown bits off the bottom of the pan and bring the mixture to a gentle simmer for 6 to 7 minutes. This will develop the base of your creamy sauce for the French Onion Gnocchi.

Step 8: Cook the Gnocchi
Once the water is boiling, add the 24 ounces of gnocchi, cooking them for a few minutes until they float to the surface. This indicates they’re perfectly cooked and ready to be added to the sauce. Drain the gnocchi, but don’t rinse them, to retain that lovely starch that helps the sauce adhere.

Step 9: Combine Gnocchi and Sauce
Carefully fold the drained gnocchi into the luscious sauce in the skillet, ensuring they are well-coated. Allow the gnocchi to simmer in the sauce for a few minutes, absorbing all those delightful flavors. This step is essential for achieving the perfect blend of creamy richness with every bite of your French Onion Gnocchi.

Step 10: Add Cheese Toppings
Sprinkle ½ cup of freshly grated Parmesan cheese over the top of the gnocchi, followed by 1½ cups of freshly grated Gruyère cheese. Place the skillet under a broiler set to high for 3 to 5 minutes, watching closely until the cheese is melted and bubbly with a golden brown crust, creating that irresistible finish.

Step 11: Garnish and Serve
Remove the skillet from the broiler and let it cool slightly. Garnish your creamy French Onion Gnocchi with more fresh thyme for added color and flavor before serving. Dish out generous portions and soak in the comforting aromas as you present this delightful skillet meal straight from the oven to your dinner table.

Expert Tips for French Onion Gnocchi

Caramelization Patience: Be patient while caramelizing onions; rushing can lead to burnt flavors. Allowing them to cook slowly enhances the depth of your French onion gnocchi.

Adjusting Sauce Consistency: If the sauce thickens too much while cooking, add a splash of beef stock or water to maintain the creamy texture you desire.

Skillet Selection: Use a broiler-safe skillet for the final baking step. This saves time and makes serving easier, ensuring your French onion gnocchi has that perfect melted cheese topping.

Taste Test Seasoning: Always taste the sauce before combining the gnocchi. Adjust salt and pepper accordingly to avoid underseasoning, making each bite deliciously fulfilling.

Cheese Variations: Experiment with different cheeses like fontina or aged cheddar for a unique twist on flavor profiles. This helps keep your French onion gnocchi exciting and versatile!

French Onion Gnocchi Recipe FAQs

How do I select ripe onions for my French Onion Gnocchi?
Absolutely! Look for yellow onions that are firm and free from dark spots or soft areas. The more vibrant the color, the sweeter the onions will be once caramelized. Shallots can also be a delightful substitute if you’re looking for a milder flavor.

How should I store leftovers of my French Onion Gnocchi?
To keep your creamy creation fresh, transfer leftovers to an airtight container and store them in the fridge for up to 3 days. When you’re ready to enjoy it again, reheat gently in the oven at 350°F for about 20 minutes to maintain that luscious creaminess.

Can I freeze French Onion Gnocchi, and if so, how?
Yes, you can! First, allow your dish to cool completely. Then, transfer it to a freezer-safe container. I recommend wrapping it tightly with plastic wrap before sealing the container to prevent freezer burn. It can last for up to 2 months. When you’re ready to eat it, simply thaw it overnight in the fridge before reheating in the oven.

What if the sauce is too thick during cooking?
Very good question! If your sauce thickens more than you’d like, just add a splash of beef stock or water and gently stir to adjust the consistency back to creamy. This will keep your French Onion Gnocchi delightful and smooth!

Are there any dietary considerations for this dish?
Certainly! For a vegetarian version, simply substitute the beef stock with vegetable broth and omit the Worcestershire sauce. Additionally, if you’re accommodating food allergies, double-check labels for any gluten-containing ingredients, and opt for gluten-free gnocchi or cornstarch as a thickening agent if needed.

Can I use homemade gnocchi instead?
Absolutely! Using homemade gnocchi can elevate your dish, giving it a gourmet touch. It’s quite the labor of love but well worth the effort for that authentic taste. If you do go this route, be sure to cook the gnocchi lightly until they float, ensuring the soft texture melds beautifully with your creamy sauce.
