Ingredients
  

  • 8 ounces of pasta penne or rotini
  • 2 tablespoons olive oil
  • 1 large onion thinly sliced
  • 2 cloves garlic minced
  • 1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 2 cups beef broth
  • 1 cup heavy cream
  • 1 cup grated Gruyère cheese
  • 1 cup grated mozzarella cheese
  • ½ cup grated Parmesan cheese
  • Fresh parsley chopped (for garnish)

Instructions
 

  • Preheat your oven to 375°F (190°C).
  • Cook the pasta according to package instructions until al dente. Drain and set aside.
  • In a large skillet, heat the olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they are caramelized and golden brown, about 15-20 minutes.
  • Add the minced garlic, thyme, salt, and pepper to the skillet. Cook for an additional 2-3 minutes until fragrant.
  • Pour in the beef broth and heavy cream, stirring to combine. Bring the mixture to a simmer and let it cook for about 5 minutes, allowing it to thicken slightly.
  • In a large mixing bowl, combine the cooked pasta with the onion mixture. Stir in half of the Gruyère, all of the mozzarella, and half of the Parmesan cheese.
  • Transfer the pasta mixture to a greased 9x13-inch baking dish. Top with the remaining Gruyère and Parmesan cheese.
  • Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown.
  • Remove from the oven and let it cool for a few minutes before serving. Garnish with fresh parsley.

Notes

  • For a vegetarian version, substitute vegetable broth for beef broth and use a plant-based cream alternative.
  • Add cooked mushrooms or spinach to the pasta mixture for extra flavor and nutrition.
