Step‑by‑Step Instructions for French Onion Gnocchi
Step 1: Caramelize Onions
In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of butter over medium heat. Add 3 sliced yellow onions, stirring to coat them in the oil. Cook for 45-60 minutes, stirring occasionally, until they turn deep brown and caramelized, releasing their sweet aromas. Patience is key, so take your time to achieve that rich flavor!
Step 2: Add Aromatics
Once the onions are beautifully caramelized, stir in 2 teaspoons of fresh thyme and 3 cloves of minced garlic. Cook for another 2 minutes until fragrant, stirring frequently to prevent the garlic from burning. Your kitchen will start to smell heavenly as the flavors blend together, setting the stage for the luscious sauce in the French Onion Gnocchi.
Step 3: Create Sauce
Pour in ½ cup of white wine to deglaze the pan, scraping up the browned bits. Allow it to simmer for about 3 minutes until it reduces by half. Then, sprinkle 2 tablespoons of flour, along with 1 tablespoon of Dijon mustard and 1 teaspoon of Worcestershire sauce, into the mix. Stir well until combined and thickened, creating a flavorful base for your dish.
Step 4: Finish Sauce
Slowly add 2 cups of beef stock and toss in a bay leaf, stirring to incorporate. Bring the sauce to a gentle simmer and let it cook for 6-7 minutes, allowing the flavors to meld beautifully. Keep an eye on the consistency; it should be creamy and invigorating! Season with kosher salt and freshly cracked pepper to taste.
Step 5: Cook Gnocchi
While the sauce simmers, bring a pot of salted water to a boil. Add the gnocchi (about 1 pound), cooking until they float to the top, which should take around 2 minutes. Drain the gnocchi well and gently fold them into the caramelized onion sauce, ensuring they are thoroughly coated with that delectable mixture.
Step 6: Bake
Preheat your oven’s broiler. Transfer the gnocchi mixture into an oven-safe dish, spreading it out evenly. Generously sprinkle ½ cup of grated Parmesan cheese and 1 cup of Gruyère cheese on top. Place it under the broiler for 4-5 minutes or until the cheese is melted, bubbly, and golden brown for that irresistible finish.
Step 7: Garnish & Serve
Remove the dish from the oven and allow it to rest for a couple of minutes. Garnish with fresh thyme for a pop of color and flavor. Serve your indulgent French Onion Gnocchi hot alongside crusty French bread or a crisp green salad for a comforting, satisfying meal that brings French bistro charm right to your table!

Make Ahead Options
These French Onion Gnocchi are perfect for meal prep enthusiasts! You can caramelize the onions and prepare the sauce up to 24 hours in advance. Simply store the sauce in an airtight container in the refrigerator to maintain its rich flavors. Additionally, you can cook the gnocchi and combine it with the sauce, refrigerating the complete dish for up to 3 days. When you're ready to serve, just preheat your oven's broiler, sprinkle the cheese on top, and broil until bubbly and golden.
