Step-by-Step Guide: How to Make Baked French Onion Gnocchi
Step 1: Caramelize the Onions
Heat olive oil in a large skillet over medium heat.
Add thinly sliced sweet onion and a pinch of salt.
Cook slowly for 20–30 minutes, stirring occasionally, until onions are:
- Deep golden brown
- Soft and tender
- Slightly sweet
Add butter during the final few minutes for extra richness.
Tip: Low and slow cooking is key. Don’t rush this step.
Step 2: Deglaze with White Wine
Pour in 1/4 cup white wine.
Scrape up any browned bits from the bottom of the pan.
Simmer for 2–3 minutes until wine reduces slightly.
This adds complexity and depth.
Step 3: Add Broth and Seasonings
Stir in:
- 2 cups beef broth
- Fresh minced thyme
- Pepper
Bring mixture to a gentle simmer.
Taste and adjust salt if needed.
Step 4: Add the Gnocchi
Add 1 lb gnocchi directly into the simmering broth mixture.
Cook according to package instructions (usually 3–5 minutes for fresh, slightly longer for frozen).
The gnocchi should become tender and absorb some of the broth.
Step 5: Transfer to Baking Dish
Preheat oven to 400°F (200°C).
Transfer the gnocchi and onion mixture into an oven-safe baking dish.
Spread evenly.
Step 6: Add the French Bread Layer
Arrange slices of French bread over the top.
You can slightly overlap them for full coverage.
Day-old bread works best because it crisps beautifully.
Step 7: Add the Cheese
Sprinkle shredded Gruyere evenly over the bread.
Make sure to cover all slices for maximum melt.
Step 8: Bake Until Golden
Bake for 15–20 minutes, or until:
- Cheese is melted
- Top is golden brown
- Edges are bubbling
For extra browning, broil for 1–2 minutes at the end (watch carefully).
