Ingredients

1 lb potato gnocchi (store-bought or homemade)
3 tbsp unsalted butter
1 tbsp olive oil
3 large onions, thinly sliced
2 garlic cloves, minced
1 tsp fresh thyme leaves
1 cup beef or vegetable broth
½ cup heavy cream

Salt and pepper to taste

Instructions

Preheat Oven: Set oven to 375°F (190°C).
Caramelize Onions: In a large skillet, melt butter with olive oil over medium heat. Add onions and cook 20–25 minutes, stirring occasionally until golden and soft. Add garlic and thyme during the last 2 minutes.
Cook Gnocchi: If using fresh gnocchi, boil per package instructions for 2–3 minutes until they float. Drain and set aside.
Combine Ingredients: In the skillet with onions, stir in broth and cream, bringing to a simmer. Season with salt and pepper.
Assemble Dish: Add cooked gnocchi to the onion mixture, stir gently, and transfer to a greased baking dish. Sprinkle Gruyère evenly over the top.
Bake: Place in preheated oven and bake 15–20 minutes, or until cheese is melted and golden.
Serve: Garnish with fresh thyme or parsley and serve hot.

Tips for Perfect Baked Gnocchi

Don’t Skip Caramelizing: Slowly cooked onions are the flavor backbone of this dish.
Gnocchi Choice: Fresh gnocchi works best; if using frozen, thaw first.
Cheese Layer: For extra richness, mix half of the Gruyère into the gnocchi mixture before baking.

Variations

Vegetarian Version: Use vegetable broth and add mushrooms or roasted red peppers.
Meaty Twist: Stir in cooked bacon or sausage for added flavor.
Spicy Kick: Add crushed red pepper flakes or a pinch of smoked paprika.

Serving Suggestions

Pair with a crisp green salad for a balanced meal.
Serve with a warm baguette to scoop up extra sauce.
Add a light drizzle of balsamic glaze on top for extra depth.
