Ingredients
  

  • 1 pound Store-bought or homemade gnocchi
  • 1 tablespoon olive oil
  • 2 large onions thinly sliced
  • 2 tablespoons butter
  • 2 cloves garlic minced
  • 2 teaspoons all-purpose flour
  • 2 cups beef or vegetable broth use less if you like a thicker sauce
  • 1/2 cup dry white wine optional
  • 1/2 teaspoon dried thyme
  • Salt and black pepper to taste
  • 1 cup Gruyère cheese shredded
  • 1/4 cup Parmesan cheese grated

Instructions
 

  • Cook the gnocchi according to the package instructions, usually by boiling them in a large pot of salted water. Once they float to the surface, cook for an additional 1-2 minutes, then drain and set them aside.
  • In a large skillet, heat the butter over medium-low heat. Add the thinly sliced onions and cook, stirring occasionally, for about 20-25 minutes or until the onions are caramelized and golden brown. Adjust the heat as needed to prevent burning.
  • Add the minced garlic to the caramelized onions and cook for another minute until fragrant.
  • Sprinkle the flour over the onions and stir to combine. Cook for 1-2 minutes to remove the raw flour taste.
  • Pour in the white wine (if using) and cook for a couple of minutes to allow the alcohol to evaporate.
  • Add the beef or vegetable broth and dried thyme, stirring to combine. Simmer for a few minutes until the sauce thickens. Season with salt and black pepper to taste.
  • Add the cooked gnocchi to the skillet with the French onion sauce. Gently stir to coat the gnocchi with the sauce and let them heat through for a couple of minutes.
  • Sprinkle the shredded Gruyère (or Swiss) cheese over the gnocchi and onion mixture. Also, sprinkle the grated Parmesan cheese over the top.
  • Place the skillet under the broiler in your oven, leaving the oven door slightly ajar. Broil for 2-3 minutes or until the cheese is melted, bubbly, and lightly browned. Keep a close eye on it to avoid burning.
  • Remove the skillet from the oven, and let it cool for a moment as it will be very hot. Serve your French Onion Gnocchi while it’s still hot and bubbling. Enjoy!
