French Onion Gnocchi is a cozy, one-skillet meal that blends the comforting essence of French onion soup with the pillowy texture of potato gnocchi. Melted Gruyère cheese finishes the dish, adding a luscious, savory top layer that’s irresistibly satisfying.

Why You’ll Love This Recipe

I love how this dish turns simple ingredients into something indulgent and full of depth. The slow-cooked caramelized onions create a rich, savory base, while the gnocchi brings a soft, chewy contrast. The Gruyère cheese melted on top is just the right touch to tie everything together. Plus, it all comes together in one pan, making cleanup a breeze.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

extra virgin olive oil
unsalted butter
yellow onions, thinly sliced
red wine
kosher salt
black pepper
garlic powder
beef broth
Worcestershire sauce
potato gnocchi, uncooked
shredded Gruyère cheese
parsley, for garnish

Directions

I start by heating olive oil and butter in an oven-safe skillet over medium heat. Once the butter melts, I add the sliced onions and cook them slowly, stirring often, until they’re deeply caramelized—about 15 to 20 minutes.
I pour in the red wine, deglazing the pan and letting it simmer until it reduces.
Then I season with salt, pepper, and garlic powder before adding the beef broth and Worcestershire sauce.
I stir in the uncooked gnocchi and let it cook for around 5 minutes until it’s tender and coated in the flavorful sauce.
Next, I sprinkle Gruyère cheese on top and place the skillet under the broiler until the cheese is melted and golden.
I finish the dish with a sprinkle of chopped parsley and serve it hot.

Servings and Timing

Servings: 4
Prep Time: 10 minutes
Cook Time: 28 minutes
Total Time: 38 minutes

Variations

I use vegetable broth instead of beef broth to make a vegetarian version.
When I don’t have red wine, I substitute it with more broth or a splash of balsamic vinegar.
For added texture, I sometimes stir in sautéed mushrooms or a handful of fresh spinach.

Storage/Reheating

I let leftovers cool and store them in an airtight container in the fridge for up to 4 days. To reheat, I use a skillet over low heat to keep the gnocchi from getting mushy, or I microwave it in short intervals until heated through. If I want the cheese topping to crisp up again, I pop it under the broiler for a couple of minutes.

FAQs

Can I use a different type of cheese?

Yes, I’ve swapped Gruyère with Swiss, Fontina, or Monterey Jack when needed. Each brings its own delicious twist.

Is it possible to make this dish ahead of time?

Definitely. I prepare everything up to the broiling step, refrigerate it, and then reheat on the stove and broil just before serving.

Can I freeze French Onion Gnocchi?

Yes. I cool the dish completely and freeze it in a sealed container for up to 2 months. When I’m ready to enjoy it, I thaw it overnight in the fridge and reheat.

What can I serve with this dish?

I like to pair it with a crisp green salad or roasted vegetables for a balanced meal.

Can I use homemade gnocchi?

Absolutely. Homemade gnocchi gives the dish a personal, rustic touch and works beautifully.
