Step-by-Step Instructions
- Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the thinly sliced onions and a pinch of salt, sautéing for 30–40 minutes.
- Optionally, sprinkle in 1 teaspoon of sugar to speed up caramelization. If onions stick, pour in ½ cup of beef broth and deglaze.
- In the same skillet, lower the heat and melt 2 tablespoons of butter. Whisk in 1 tablespoon of flour, cooking until bubbling.
- Gradually add 3 cups of heavy cream while whisking until thickened, about 5 minutes. Stir in two-thirds of caramelized onions.
- Bring a large pot of salted water to a boil. Add 12 ounces of cavatappi and cook until just shy of al dente, about 7-8 minutes.
- Combine cooked pasta with béchamel sauce in a large mixing bowl. Add reserved pasta water if too thick.
- Transfer the mixture to a greased baking dish, layer the remaining onions on top, and sprinkle with breadcrumbs.
- Preheat oven to 350°F (175°C) and bake the dish uncovered for 10–15 minutes until golden and crispy.
- Remove from the oven, let cool briefly, and serve warm, garnished with fresh parsley.

Notes
Use yellow onions for the best sweetness. Low and slow caramelization is key. Store leftovers in an airtight container for 3-4 days.
