French Onion Gnocchi Ingredients

• Take a look at what you’ll need to create this comforting dish!

For the Gnocchi Base

  • Gnocchi (24 oz.) – The star of the dish; these soft potato dumplings absorb the rich sauce beautifully.
  • Yellow Onion (2 lbs.) – Essential for creating that sweet, caramelized base; don’t skimp on the quantity!
  • Olive Oil – Adds richness and aids in caramelizing the onions; butter can be used as a tasty substitute.
  • Salted Butter – Enhances the flavor while frying; use unsalted if you prefer to control the saltiness.
  • Kosher Salt – Season to taste, considering the saltiness of the broth you choose.
  • Black Pepper – Adds warmth and depth; freshly cracked is recommended for the best flavor.

For the Flavorful Sauce

  • Thyme (1½ tbsp.) – Infuses the dish with aromatic herbal notes; fresh rosemary or sage can also be fantastic alternatives.
  • Garlic (6 cloves) – Elevates the flavors with robust notes; adjust according to your flavor preference.
  • Dry White Wine (½ cup) – Adds complexity and balances richness; switch to broth for a non-alcoholic version.
  • Dijon Mustard (2½ tsp.) – Introduces a tangy depth; no substitutes necessary here.
  • All-Purpose Flour (2½ tbsp.) – Thickens the sauce perfectly; cornstarch or gluten-free flour works as a substitution if needed.
  • Worcestershire Sauce (1 tsp.) – Adds a lovely umami depth; it’s best to stick with this ingredient.
  • Bay Leaf (1 large) – Infuses the sauce with herbal undertones; remember to remove it before serving.
  • Beef Stock (2½ cups) – Forms the rich sauce base; low sodium options help control salt levels. Use vegetable broth if a lighter version is desired.

For the Cheesy Topping

  • Gruyère Cheese (1½ cups) – This melted topping adds creaminess and flavor; swap with Swiss or mozzarella if needed.
  • Parmesan Cheese (½ cup) – Sprinkled on top for that salty, nutty flavor when melted; Pecorino Romano can provide a sharper taste.

Gather these ingredients, and you’re all set to create a dish that’s as comforting as a warm hug—your very own French Onion Gnocchi awaits!

Step‑by‑Step Instructions for French Onion Gnocchi

Step 1: Sauté the Aromatics
In an 11-inch skillet, heat 2 tablespoons of olive oil and 2 tablespoons of salted butter over medium heat until melted and bubbly. This should take about 1-2 minutes. Add the 2 lbs of sliced yellow onions and stir occasionally, ensuring they are well coated in the oil and butter, allowing them to begin caramelizing, which will take approximately 45-60 minutes. If they start to brown too quickly, add a splash of water to prevent burning.

Step 2: Add Herbs and Garlic
Once the onions have reached a deep, golden brown color, about 60 minutes in, toss in 1½ tablespoons of thyme and 6 minced garlic cloves. Stir continually for about 2 minutes, allowing the garlic to release its fragrance and mingle with the sweet caramelized onions. The delightful aroma will fill your kitchen, signaling that your French Onion Gnocchi is coming together beautifully.

Step 3: Pour in the Wine
Next, pour in ½ cup of dry white wine, scraping up any browned bits from the bottom of the skillet for extra flavor. Increase the heat slightly to medium-high, cooking the mixture until the wine has reduced by half, which should take roughly 3-4 minutes. This will deepen the complexity of the sauce, enhancing the overall taste profile of your French Onion Gnocchi.

Step 4: Thicken the Sauce
Sprinkle in 2½ tablespoons of all-purpose flour, stirring continuously for 1-2 minutes until the mixture thickens. Be sure to thoroughly integrate the flour to avoid any lumps. Add 2½ teaspoons of Dijon mustard and 1 teaspoon of Worcestershire sauce, stirring well to incorporate them into this rich base for the sauce, turning down the heat to medium.

Step 5: Create the Sauce Base
Gradually pour in 2½ cups of beef stock and add 1 large bay leaf. Increase the heat to bring the sauce to a gentle boil, then reduce to a simmer. Let it cook until the sauce reduces slightly, about 6-7 minutes; the sauce should be thicker and flavorful. Now is the time to season with kosher salt and freshly cracked black pepper to your liking.

Step 6: Cook the Gnocchi
In a separate pot, bring salted water to a boil and add 24 oz of gnocchi. Cook until they float to the surface, which typically indicates they are done; this should take about 2-3 minutes. Once cooked, drain the gnocchi and immediately add them to the skillet with the onion sauce, gently folding to coat each piece in the luscious flavor.

Step 7: Broil to Perfection
Preheat your broiler to high. In the skillet, sprinkle 1½ cups of grated Gruyère cheese and ½ cup of Parmesan cheese evenly over the gnocchi. Place the skillet under the broiler, watching closely, and broil for 3-5 minutes until the cheese is melted, bubbly, and golden. This step adds a deliciously gooey texture that elevates your French Onion Gnocchi.

Step 8: Garnish and Serve
Remove the skillet from the oven and carefully take out the bay leaf. Garnish your decadent French Onion Gnocchi with a sprinkle of fresh thyme for a pop of color and flavor. Serve immediately while hot, ideally alongside crusty bread or a refreshing salad to complete this comforting meal—a true delight that brings warmth to your table!

What to Serve with Decadent French Onion Gnocchi Skillet

As the warm aroma of cheese and caramelized onions fills the air, you might be wondering what delightful additions can complete this cozy meal.

  • Crusty Bread: This is a classic partner for French Onion Gnocchi, perfect for soaking up every bit of that rich sauce. A warm, buttery baguette can elevate the entire experience.

  • Simple Leafy Salad: A fresh salad with mixed greens and a tangy vinaigrette cuts through the creamy richness of the gnocchi. Light and crisp, it’s a refreshing contrast that complements every bite perfectly.

  • Roasted Asparagus: The earthy flavor and slight crunch of roasted asparagus provide a lovely texture contrast, making it a delicious and nutritious side dish that won’t overshadow the gnocchi.

  • Creamy Mashed Potatoes: If you’re looking for ultimate comfort, serve alongside creamy mashed potatoes. They’re a dreamy, buttery addition that harmonizes wonderfully with the flavorful sauce.

  • Garlic Green Beans: Crisp-tender green beans sautéed with garlic add a crunchy element to the meal. Their bright color and flavor balance the richness of the gnocchi beautifully.

  • Chardonnay or Sauvignon Blanc: A glass of crisp white wine not only enhances the dining experience but also pairs wonderfully with the savory elements of this dish. The acidity helps cleanse the palate after each luxurious bite.

Make Ahead Options

These French Onion Gnocchi are perfect for meal prep enthusiasts! You can sauté the onions and prepare the rich sauce up to 24 hours in advance; just allow it to cool completely before refrigerating in an airtight container. When you’re ready to serve, simply reheat the sauce on the stovetop while you cook the gnocchi, which only takes about 2-3 minutes to float. Additionally, you can cook the gnocchi ahead of time and refrigerate them for up to 3 days. To maintain quality, ensure the sauce is well-seasoned and avoid overcooking when reheating. Finish with broiling the cheese for that golden, bubbly top just before serving to enjoy this delightful French Onion Gnocchi at its best!
