Ingredients
Scale
- 3 tablespoons unsalted butter
- 3 large yellow onions (thinly sliced)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
- 2 garlic cloves (minced)
- 2 tablespoons all-purpose flour
- ½ cup dry white wine (optional, can sub extra broth)
- 3 cups beef broth (low sodium)
- 1 pound penne (or similar)
- 1 cup Gruyère cheese (shredded)
- 1 cup mozzarella cheese (shredded)
- ½ cup Parmesan cheese (grated)
Instructions
- Preheat the oven to 375°F.
- Melt the butter in a large oven-safe skillet or Dutch oven over medium heat. Add the onions, salt, and pepper. Cook for 20 to 25 minutes, stirring often, until the onions are deeply caramelized.
- Stir in the thyme and garlic. Cook for 1 minute, then sprinkle the flour over the onions. Stir and cook for another 1 to 2 minutes.
- Pour in the wine, scraping up any browned bits, and cook until mostly evaporated, about 2 minutes. Stir in the beef broth and bring to a simmer.
- Meanwhile, cook the pasta in a large pot of salted boiling water until just shy of al dente. Drain well.
- Add the pasta to the onion mixture and stir to coat. Sprinkle with Gruyère, mozzarella, and Parmesan cheese.
- Transfer the skillet to the oven and bake for 15 to 20 minutes, until the cheese is melted and bubbly.
- Serve hot, garnished with extra thyme if desired.
Notes
- Use low sodium beef broth for better control of saltiness.
- Feel free to substitute pasta shapes based on preference.
- Garnish with fresh herbs for added flavor.
