How to Make French Onion Soup Pasta

1. Step 1: Preheat your oven to 350°F (175°C). This ensures your French Onion Soup Pasta bakes up golden and bubbly, just like a traditional French onion soup pasta bake.
2. Step 2: Slice 1/2 baguette and pulse in a food processor to create coarse breadcrumbs. Toss them with 1 tbsp olive oil, 1 tsp oregano, and a pinch of salt for a crunchy topping. Set these aside for later.
3. Step 3: Thinly slice 5 onions into long strips. The aroma will begin to fill your kitchen, and this is the first step in how to make French onion soup pasta with real depth.
4. Step 4: In a large skillet, heat olive oil over medium. Add onions and sauté for 30–40 minutes, stirring every so often, until they turn rich and caramel brown. Sprinkle in 1 tsp sugar halfway through to encourage that caramelized sweetness.
5. Step 5: If onions start sticking, pour in 1/2 cup beef broth and gently simmer for 10 minutes, letting the liquid reduce and the flavor intensify. Set the onions aside when deeply golden.
6. Step 6: Using the same skillet, melt 2 tbsp butter over low-medium heat. Stir in 1 tbsp flour and cook for 1 minute, then slowly whisk in 3 cups heavy cream to form a silky béchamel. Use 3 tbsp water if needed to smooth out lumps.
7. Step 7: Fold in two-thirds of the caramelized onions. Add 1 cup parmesan cheese, 1 tsp salt, pepper, parsley, 1 tbsp garlic powder, 1 tbsp smoked paprika, 1/2 tsp nutmeg, and 1 tsp oregano. Let the sauce gently simmer for 2–3 minutes—it should smell creamy and savory, like the best one pot French onion pasta ever.
8. Step 8: Meanwhile, boil a large pot of salted water. Cook 300 g cavatappi macaroni just shy of al dente, about 7–8 minutes. Drain, reserving 1/4 cup pasta water.
9. Step 9: In a large bowl, toss the cooked pasta with your luscious onion béchamel sauce. Add a splash of reserved pasta water if you want a creamier result.
10. Step 10: Transfer the mixture to a greased baking dish. Top evenly with remaining caramelized onions and your homemade breadcrumbs for that irresistible French onion pasta bake texture.
11. Step 11: Bake uncovered for 10–15 minutes until the top is crisp and golden, and the scent is absolutely mouthwatering.
12. Step 12: Serve hot, garnished with extra parsley and parmesan if you like. Every forkful of this homemade French onion soup pasta casserole is pure comfort—creamy, cheesy, and packed with sweet, savory onion flavor.
