Every component of this dish adds another dimension of flavor and the radiatori makes it fun to eat. When I was growing up, pasta was part of our daily diet. Whether it was a dried pasta dish, like Penne Pomodoro or a fresh homemade pasta, it was part of our dinner just about everyday.

As a kid the short squat pasta shapes were my favorite because of the way they held on to thick sauces and they were easier to eat. I have to admit not much has changed! Now Casarecce with Pesto is one of my favorites. If you want to try a tasty long pasta give Trenette al Pesto a go!

What is radiatori pasta?

Radiatori is a short pasta shape that appears to resemble the grill of a radiator from an automobile. To some they look like old-fashioned heating fixtures. There is some debate about it’s origin, but the inspiration for it’s shape seems to have come from the Italian auto industry. Some say that it was first introduced between WWI and WWII, while others contend that it was created around 1960.

Radiatori is typically made from durum wheat semolina flour, which produces a high gluten pasta that holds up well and cooks to a lovely al dente bite. It is made using an extrusion type of mold that creates a rough surface, so the pasta is able to stand up to hearty sauces.

Radiatori pasta is wonderfully versatile. Similar to rotini and other squat pasta shapes, radiatori are great for holding chunky sauces like this one. The folds and curves also work well with creamy sauces, soup, pasta salad and baked pasta.

Ingredients notes and substitutions

As with most Italian dishes, simple ingredients create great flavor. That is why when it comes to food, in order to have the best experience you should use fresh premium ingredients.

  • Pancetta adds a smokey pork flavor to the pasta but if you can’t find it you can substitute a thick good quality bacon instead.
  • Sun-dried tomatoes are one of the main components to this dish. They have a much more concentrated sweetness then fresh tomatoes and they add a delightful texture to the dish. You can use a dried version or those preserved in oil. If you use the dried version, they will need to be reconstituted in boiling water before chopping them and adding them to the dish.
  • The white wine can be any variety you like. I prefer something a little more oaky and robust like a Chardonnay. Just make sure that you enjoy the flavor of the wine as it will become more concentrated as it cooks.
  • Spinach is the other main ingredient in this chunky sauce and for this dish I like using frozen spinach that has been thawed. Don’t bother straining the liquid out, just go ahead and add it to the sauce.
  • Pecorino Romano cheese provides a wonderful saltiness to the dish. You can substitute grated parmesan.
  • Radiatori Pasta is the star ingredient, but if you can’t find it, you can substitute other similar pastas like rotini, girelli, campanelle, or cavatappi.

Radiatori pasta FAQ’s

How long does it take to cook radiatori pasta?

In this recipe I am using a dried pasta product, which takes about 8-12 minutes to cook. I recommend following the package instructions for the brand you are using. If you are using fresh pasta, the cooking time would be closer to 3 minutes.

Generally cooking times will vary slightly depending on how al dente (toothy) you want the pasta to be when you add it to your sauce. In most cases the pasta will continue to cook in the sauce so you will want to remove from the boiling water closer to the 8 minute mark. In this recipe you will simply be tossing the pasta with the spinach mixture so you can allow it to cook a little longer.

What can you serve with Radiatori with Spinach and Sun-Dried Tomatoes?

This pasta dish can be served as your main course with a side salad. You can also make this your first course or a “primo” as they do in Italy. Follow it with a meat course like Grilled Lollipop Lamb Chops or Lemon Pepper Salmon with Dill.

Where can you buy Radiatori pasta?

For a while most supermarkets imported this pasta from Italy and many still do. Most recently, more US pasta companies have been producing radiatori as well. Some of the more common brands available are Colvita, Anna and Garofalo. You can find radiatori in many local grocery stores and Italian food stores. Wegmans, Walmart and Target all carry this shape under their own brand, along with other less common pasta shapes.
