Inspired by the classic French onion soup, this skillet dinner transforms simple ingredients like caramelized onions, tender gnocchi, and rich, melty cheese into a hearty, one-pan dish perfect for weeknight dinners or casual entertaining.

How To Make French Onion Gnocchi Skillet

The Ingredients

Onion: Onions are the heart of this dish, caramelized slowly to bring out their natural sweetness and rich flavor.
Substitutes: Shallots for a milder flavor, leeks for a softer onion taste, or yellow onions if you want a slightly stronger taste.

Butter: Butter adds richness and helps caramelize the onions to a beautiful golden brown.
Substitutes: Olive oil, avocado oil, or plant-based margarine for a dairy-free version.

Gnocchi: Gnocchi are soft potato dumplings that soak up the sauce and provide a tender, pillowy texture.
Substitutes: Sweet potato gnocchi, cauliflower gnocchi for a low-carb option, or even small pasta shapes like mini shells or tortellini.

Broth: Broth adds moisture and savory depth to the dish, enhancing the onion flavor and helping cook the gnocchi.
Substitutes: Vegetable broth, chicken broth, beef broth, or mushroom broth for an earthy twist.

Balsamic Vinegar: Balsamic vinegar adds a touch of acidity and sweetness that brightens the caramelized onions and balances the richness of the cheese.
Substitutes: Red wine vinegar, apple cider vinegar, or sherry vinegar.

Mozzarella and Gruyère: Mozzarella melts beautifully for gooey stretchiness, while Gruyère adds a nutty, slightly sweet flavor that’s classic in French onion dishes.
Substitutes: Provolone, fontina, Emmental, or Swiss cheese. For a dairy-free option, try vegan mozzarella and cashew-based cheese alternatives.

Chives: Chives garnish the dish with a fresh, mild onion flavor and a pop of green color.
Substitutes: Green onions, parsley, or thyme.
