How to Make Simple Baked French Onion Gnocchi

1. Preheat Oven

Preheat your oven to 400°F (200°C). Greasing the baking dish ahead of time prevents sticking.

2. Caramelize the Onions

In a large skillet or Dutch oven, melt the olive oil and butter over medium heat.
Add the thinly sliced sweet onions and cook slowly, stirring occasionally, until deeply golden and caramelized—about 20 minutes. The slower the onions cook, the sweeter and more flavorful they become.

3. Deglaze and Build the Sauce

Pour in the white wine to deglaze the pan, scraping up any browned bits from the bottom.
Add the minced thyme and beef broth, then bring the mixture to a simmer. This creates a rich, flavorful sauce that coats the gnocchi.

4. Cook the Gnocchi

Add the gnocchi to the skillet and stir occasionally over medium heat. Cook until the gnocchi is tender and the sauce has slightly thickened, about 5–10 minutes. Season with salt and pepper to taste.

5. Assemble for Baking

Transfer the gnocchi and onion mixture to a greased medium baking dish, spreading it evenly.
Top with shredded Swiss or Gruyère cheese, ensuring a uniform layer for a golden, bubbly finish.

6. Bake

Bake in the preheated oven for 20–25 minutes, or until the cheese is lightly browned and the gnocchi is bubbly. Remove from the oven and allow to cool slightly before serving.

7. Serve

Serve hot, with slices of French bread on the side for dipping. Enjoy the cheesy, savory goodness with every bite.

Tips for Success

• Take your time caramelizing onions – This step is key to a sweet, deeply flavorful sauce.
• Use day-old bread – For better texture if serving on the side.
• Gruyère is ideal – But Swiss cheese works well for a milder flavor.
• Simmer gnocchi gently – Avoid over-stirring so they don’t break apart.
• Season to taste – Adjust salt and pepper after the sauce reduces.

Recipe Variations

Herb-Enhanced Gnocchi
Sprinkle fresh rosemary or sage over the top before baking for aromatic depth.

Creamy Option
Add a splash of heavy cream or plant-based cream to the sauce before baking for extra richness.

Serving Suggestions

• Serve with French bread slices for dipping
• Pair with a fresh green salad for a lighter side
• Top with extra thyme or parsley for freshness and color
• Perfect as a main dish or hearty side for dinner parties
