Ingredients

Scale

Breadcrumbs

  • ½ Baguette
  • 1 tablespoon Olive Oil
  • 1 teaspoon Salt
  • 1 teaspoon Pepper
  • 2 teaspoons Oregano

Pasta Ingredients

  • 300 g Cavatappi Macaroni
  • 5 Onions, thinly sliced
  • ½ cup Beef Broth
  • 3 cups Heavy Cream
  • 1 cup Parmesan Cheese, grated
  • 1 tablespoon Flour + 3 tablespoons water (for béchamel)
  • 1 teaspoon Sugar
  • Fresh Parsley, chopped (to taste)
  • 2 teaspoons Salt
  • 1 tablespoon Garlic Powder
  • 1 tablespoon Smoked Paprika Powder
  • ½ teaspoon Nutmeg

Instructions

  1. Slice Onions: Thinly slice the onions into long strips to ensure even caramelization and a tender texture in the final dish.
  2. Caramelize Onions: Heat olive oil in a large skillet over medium heat and sauté the onions for 30–40 minutes, stirring occasionally. Allow them to caramelize slowly without burning. Optionally, add 1 teaspoon of sugar to speed up caramelization. If onions stick, add beef broth and simmer for 10 more minutes until fully caramelized, then set aside.
  3. Prepare Béchamel Sauce: In the same skillet, melt butter over low to medium heat. Whisk in flour and cook for one minute. Gradually add heavy cream while whisking to avoid lumps. If the sauce lumps, add ice-cold water and whisk vigorously to smooth it out.
  4. Combine Onions and Season Sauce: Stir in two-thirds of the caramelized onions into the béchamel sauce. Simmer and season with salt, pepper, chopped parsley, and 1 cup of grated Parmesan cheese, enhancing the creamy depth of flavor.
  5. Cook Pasta: Boil a large pot of salted water and cook cavatappi macaroni until just shy of al dente, as the pasta will finish cooking in the oven.
  6. Mix Pasta and Sauce: Combine the drained pasta with the béchamel onion sauce, mixing thoroughly to ensure every piece is coated.
  7. Prepare Breadcrumb Topping: Tear or cube the baguette. Toss with olive oil, salt, pepper, and oregano. Optionally, air fry or toast in the oven until golden and crisp.
  8. Assemble and Bake: Transfer the pasta mixture to a baking dish. Top with the remaining one-third of caramelized onions and then sprinkle the prepared breadcrumbs evenly over the top.
  9. Bake: Bake uncovered at 350°F (175°C) for 10–15 minutes, or until the top is golden and crisp, and the dish is heated through.
  10. Serve: Serve immediately for a warm, comforting, and flavorful pasta dish that captures the essence of French onion soup.

Notes

  • You can speed up onion caramelization by adding a teaspoon of sugar, but it is optional.
  • If béchamel sauce gets lumpy, add ice-cold water slowly and whisk vigorously to smooth it.
  • Cooking pasta just shy of al dente ensures it does not overcook during baking.
  • Breadcrumbs can be air-fried or toasted in the oven for extra crispiness.
  • Using beef broth enhances the classic French onion flavor, but you can substitute with vegetable broth for a lighter taste.
