How to Make French Onion Gnocchi

Step 1: Caramelize the Onions
In a large skillet or Dutch oven, heat olive oil and butter over medium.

Add thinly sliced onions and stir occasionally for about 20 minutes until deeply golden and soft.

Step 2: Deglaze and Simmer
Pour in white wine and scrape up any browned bits.

Add minced thyme and beef broth. Bring to a simmer.

Step 3: Cook the Gnocchi
Stir gnocchi into the broth.

Let simmer for 5–10 minutes until gnocchi is tender and the sauce has reduced and thickened.

Season with salt and pepper.

Step 4: Bake with Cheese
Transfer everything to a greased medium baking dish.

Top with shredded cheese.

Bake at 400°F for 20–25 minutes until cheese is melted and bubbly.

Step 5: Toast and Serve
Serve with slices of toasted French bread for scooping up all that cheesy goodness.
