How to Make French Onion Gnocchi

Sauté Onions: In a large oven-safe skillet over medium heat, add olive oil and butter. Once melted, add the thinly sliced onions and sauté for 15-20 minutes until they turn deeply caramelized and golden.
Deglaze with Wine: Once the onions are caramelized, pour in the red wine. Stir and cook until the wine fully evaporates, letting the rich flavors intensify.
Season & Combine: Sprinkle in salt, black pepper, and garlic powder. Pour in the beef broth and Worcestershire sauce, stirring well. Bring this hearty mixture to a gentle simmer.
Cook Gnocchi: Reduce the heat to low, then add the uncooked gnocchi. Let it simmer for 3-5 minutes until the gnocchi become tender and fluffy.
Broil with Cheese: Evenly distribute the Gruyère cheese over the top of the gnocchi and sauce. Broil in the oven for 2-3 minutes, or until the cheese is melted and lightly browned, creating a luscious crust.
Garnish & Serve: Carefully remove from the oven, sprinkle fresh parsley on top for color, and serve hot for an inviting, comforting meal.

Optional: Pair with crusty bread for a delightful dip into the cheesy goodness.

Expert Tips for French Onion Gnocchi

Caramelization Mastery: Take your time with the onions; they should be deeply caramelized to develop that rich, sweet flavor essential for this French onion gnocchi.
Wine Selection: Use a good quality red wine for deglazing; it will elevate the sauce. If you prefer not to use alcohol, vegetable broth works just fine!
Precise Gnocchi Cooking: Don’t overcook the gnocchi; simmer them just until they float to achieve that perfect tender texture without mushiness.
Cheese Watch: Keep an eye on the cheese while broiling; it can go from perfectly browned to burnt in a flash!
Extra Flavor Boost: Consider adding fresh herbs like thyme or sautéed mushrooms while cooking the onions for even more depth in your dish.

Make Ahead Options

These French Onion Gnocchi are a fantastic choice for busy weeknights and meal prep lovers! You can prep the caramelized onion and broth sauce up to 24 hours in advance, allowing the flavors to deepen overnight in the refrigerator. Simply sauté the onions, deglaze with wine, and combine with the broth as usual; then allow it to cool, cover it in an airtight container, and refrigerate. The gnocchi should be added fresh, so cook those just before serving to maintain their pillowy texture. When ready to enjoy, reheat the sauce in a skillet, add the uncooked gnocchi, and simmer for about 3-5 minutes until tender. Top with cheese and broil for that gooey finish!

French Onion Gnocchi Recipe FAQs

What type of onions work best for this recipe?
For the best flavor, I recommend using yellow onions. They become wonderfully sweet when caramelized, which is essential for achieving that rich depth typical of French onion dishes. You can also experiment with sweet onions, but avoid red onions as they may alter the flavor profile.

How should I store the leftovers?
Absolutely! Leftover French onion gnocchi can be stored in an airtight container in the refrigerator for up to 3-4 days. Just make sure to cool the dish completely before sealing it to maintain its freshness. When reheating, add a splash of broth on the stove to keep it from drying out.

Can I freeze French onion gnocchi?
Very much so! You can freeze the gnocchi for up to 2 months. Follow these instructions: first, spread the gnocchi in a single layer on a baking sheet and freeze until firm. Then, transfer them to a freezer-safe container or bag, removing as much air as possible to prevent freezer burn. For best results, thaw them overnight in the fridge before reheating.

What should I do if my gnocchi become mushy?
If your gnocchi feel mushy, it may be due to overcooking. I suggest that in the future, cook them until they float to the surface, which typically ensures they are tender but not overdone. If they do get mushy, consider adding a thicker sauce base or topping with more cheese for extra texture.

Is this dish safe for my pets?
It’s best to avoid sharing this dish with pets. Ingredients like onions and garlic are toxic to dogs and cats, so I wouldn’t recommend giving them even small portions. Always stick to pet-safe foods if you’re looking to treat your furry friends!

Can I adjust the recipe for vegetarian diets?
Absolutely! For a vegetarian version of French onion gnocchi, simply substitute beef broth with vegetable broth and omit Worcestershire sauce, or use a vegan-friendly alternative. This way, you can enjoy all the flavors without compromising dietary preferences.
