Ingredients
  

Main ingredients

  • 1 pound potato gnocchi Use store-bought for speed.
  • 4 tablespoons unsalted butter Controls seasoning.
  • 2 tablespoons olive oil Prevents butter from browning too fast.
  • 4 large yellow onions, thinly sliced Sweet onions caramelize beautifully.
  • 1 teaspoon sugar Speeds up caramelization.
  • Salt to taste Layer it during cooking.
  • Black pepper to taste Freshly cracked is better.
  • 2 cloves garlic, minced Add toward the end of sautéing.
  • 2 tablespoons all-purpose flour For the roux.
  • 1 cup beef broth Use a good-quality broth.
  • 1 cup whole milk Adds creaminess.
  • 1 teaspoon fresh thyme leaves Can substitute dried at 1/3 amount.
  • 1 cup Gruyère cheese, grated Nutty and melty.
  • 1/2 cup Parmesan cheese, grated Adds sharpness.
  • 1 cup mozzarella cheese, shredded For gooey texture.
  • Fresh thyme sprigs for garnish For presentation.

Instructions
 

Preparation

  • Preheat the oven to 375°F (190°C).
  • Melt 2 tablespoons of butter with 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions, sugar, salt, and black pepper.
  • Caramelize the onions on medium-low heat for about 25–30 minutes, stirring occasionally, until deeply golden brown.
  • Meanwhile, bring a pot of salted water to a boil. Add the gnocchi and cook until they float, about 2–3 minutes. Drain and set aside.
  • Remove half of the caramelized onions and set aside for topping. Add the remaining 2 tablespoons of butter to the skillet, melt, and then add minced garlic. Cook for about 30 seconds.
  • Stir in the flour to make a roux, cooking for about a minute, then gradually whisk in the beef broth and whole milk. Simmer until thickened, about 3–5 minutes.
  • Gently fold the gnocchi and half of the caramelized onions into the sauce.

Baking

  • Transfer the mixture to a baking dish. Top with Gruyère, Parmesan, and mozzarella, then layer on the reserved caramelized onions.
  • Bake for 15–20 minutes until the cheese is melted and bubbly. Rest for 5 minutes before serving.

Notes

Don't rush the caramelization process. Freshly grate your cheeses for optimal melting, and taste as you cook to adjust seasoning.
