Ingredients
Pasta
- 500 grams dry rigatoni pasta (about 1 lb)
Sauce
- 2 tablespoons salted butter
- ½ small onion, finely diced
- 1 tablespoon finely minced fresh garlic (3-4 cloves)
- 1 teaspoon salt
- ½ teaspoon Italian seasoning
- ⅛-¼ teaspoon crushed red pepper flakes (¼ teaspoon for some heat, ⅛ for mild)
- ¼ teaspoon black pepper
- 1 tablespoon all-purpose flour
- 1½ cups heavy cream (or substitute half and half)
- 1½ cups tomato pasta sauce (marinara or other)
- 3 tablespoons freshly grated Parmesan cheese
Instructions
- Cook the Pasta: Bring a large pot of salted water to a rolling boil over high heat. Add rigatoni, reduce heat to medium, and cook until al dente according to package directions.
- Prepare the Base: While the pasta is cooking, melt butter in a large skillet over medium heat. Add the finely diced onion and cook until softened and just beginning to brown.
- Sauté Aromatics: Stir in minced garlic, salt, Italian seasoning, crushed red pepper flakes, and black pepper. Cook for about 1 minute, being careful not to let the garlic burn.
- Create Roux: Stir in all-purpose flour until no white flour remains, forming a roux to thicken the sauce.
- Add Cream and Tomato Sauce: Pour in the heavy cream and tomato pasta sauce, stirring to combine. Simmer over medium heat until the sauce is slightly thickened.
- Drain Pasta: When pasta is cooked, reserve 1 cup of pasta water and drain the rigatoni.
- Combine Pasta and Sauce: Return the cooked pasta to the skillet with the sauce. Stir in reserved pasta water a little at a time (starting with ¼ cup) as needed to bring the sauce together and achieve desired consistency.
- Finish and Serve: Sprinkle freshly grated Parmesan cheese over the pasta, stir gently to combine, and serve immediately.
Notes
- Use half and half instead of heavy cream for a lighter sauce if preferred.
- Adjust crushed red pepper flakes according to your desired spice level.
- Reserving pasta water is key to bringing the sauce and pasta together smoothly.
- Use freshly grated Parmesan for best flavor and texture.
