How to Make It

Follow these simple steps to prepare your creamy pasta dish.

Cook the Pasta

Bring a large pot of salted water to a boil. Add the radiatore pasta and cook according to the package directions (typically 10-11 minutes). Drain and set aside, reserving about ½ cup of the pasta water.

Sauté the Onion

In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook for about 5 minutes, stirring occasionally, until the onion is soft and translucent.

Add Tomato Paste and Seasonings

Reduce heat to low. Add the tomato paste, minced garlic, salt, dried basil, and red pepper flakes. Stir well and cook for 1-2 minutes to bring out the flavors.

Add Cream and Parmesan

Pour in the heavy cream, stirring to combine. Bring the sauce to a gentle simmer, then add the grated Parmesan, stirring until the cheese is fully melted and the sauce is smooth.

Combine Pasta and Sauce

Add the cooked radiatore pasta to the skillet, tossing to coat each piece in the creamy sauce. If the sauce is too thick, add a little reserved pasta water to reach your desired consistency.

Serve

Serve the pasta hot, garnished with extra Parmesan if desired. Enjoy!

How to Store It
