How to Make Creamy Spinach Rigatoni
Making this comforting dish is straightforward and beginner-friendly. You’ll start by sautéing onions and then add your cream and spices to create the sauce. Finally, mix in the rigatoni and spinach for a delightful meal that brings everything together.
What You Need
- 3 cups fresh spinach
- 2 tablespoon unsalted butter
- 1 medium onion (finely diced)
- 2 cups heavy cream
- 1 cup Parmesan cheese (freshly grated)
- 1 tablespoon all-purpose flour
- ¼ teaspoon ground nutmeg
- 1 ½ teaspoon salt
- 8 oz rigatoni (cooked al dente)
Cooking Steps
On medium high heat, melt the butter with some olive oil. Add the diced onion and 1 teaspoon of salt, sautéing for 5 minutes until the onion turns soft and translucent. Pour in the heavy cream and let it cook, stirring frequently, until it thickens, about 5 minutes. In a small bowl, whisk the flour with 3 tablespoons of water until smooth. Stir the flour mixture into the sauce and cook for another 5 minutes until the sauce thickens further. Stir in the grated Parmesan cheese, ground nutmeg, and fresh spinach. Simmer until the spinach wilts, about 3-5 minutes. Add the cooked rigatoni to the skillet and toss to coat the pasta evenly in the creamy spinach sauce. Serve & enjoy!

When you’re ready to enjoy it again, simply reheat in a pot over low heat, adding a splash of cream if the sauce has thickened too much.
Recipe Tips
