Seafood lovers, rejoice. You’re going to love this easy Italian pasta recipe for Seafood Linguine fra Diavolo!

Fra Diavolo is Italian for “Brother Devil,” and is the name for a spicy red sauce served with pasta, seafood, or both. This recipe is so simple, so delicious, and uses only four ingredients and takes 20 minutes to make, start to finish. No joke. Perfect for a busy weeknight, but special and tasty enough to serve at a dinner party.

It’s easy to control the amount of spice in this recipe based on personal preference. All you need is seafood (I used a bag of frozen mixed seafood… more on the specifics later), marinara sauce, linguine, and crushed red pepper to make this (along with some salt and olive oil).

Let’s get to it!

Ingredients and Substitutions

  • Seafood – I used a 1 lb. bag of frozen mixed seafood, which included shrimp, calamari, octopus, and mussels. You can use any kind of seafood, frozen or fresh, cooked or uncooked, for this recipe. Shrimp, calamari, lobster, crawfish, octopus, mussels, clams… anything and everything goes here! (A note on fish: it may not hold up well in the sauce and flake apart too much- shellfish and sturdy seafood are best here.)
  • Marinara sauce – I recommend homemade marinara sauce or Rao’s, but any kind of prepared marinara sauce will do.
  • Linguine – or another kind of pasta. I prefer long pasta for this, such as fettuccini or spaghetti.
  • Crushed red pepper – for the spiciness Fra Diavolo sauce is known for.
  • Fresh Parsley – optional, but adds a little something-something and some beautiful color.
  • Olive oil and Kosher Salt

How to make Seafood Linguine with Fra Diavolo Sauce

  1. First, COOK THE PASTA according to the directions in heavily salted water until 1 minute before al dente.
  2. Then, SAUTÉ the seafood with crushed red pepper in olive oil in a large skillet. Make sure you pat the seafood dry first.
  3. ADD MARINARA SAUCE to the seafood and heat up.
  4. TRANSFER THE COOKED PASTA directly to the sauce using tongs. This will help the pasta water cling to it and thicken the sauce. Also add 1/2 cup of the pasta cooking water to the sauce. The starches from the water will help thicken the sauce and make it stick to the pasta.
  5. FINISH COOKING THE PASTA directly in the sauce for 1-2 more minutes, until it’s thickened up and clings to the pasta.
  6. SERVE with parmesan, parsley, olive oil, black pepper, and more crushed red pepper if desired.

How to defrost frozen seafood

Just leave it in the fridge for 24 hours, or if you need it sooner than that, run cool water over it in a colander until it’s defrosted. You can also soak it in cool water until it’s thawed.

How to make the fra diavolo extra spicy

You can use a pre-made arrabbiata sauce (Rao’s makes a good arrabbiata) in place of regular marinara sauce. Arrabbiata is already spicy, so this with the crushed red pepper will add some fire to the sauce!

You can also just add a lot of crushed red pepper to your personal taste preference to make it extra spicy (and use less for a mild version).

  • 16 oz. linguine (or another long pasta shape, such as fettuccini or spaghetti)
  • kosher salt
  • 1 – 1 1/2 lb. seafood such as shrimp, scallops, and/or calamari (see notes)
  • 2 tablespoons extra-virgin olive oil
  • 1/2-1 teaspoon crushed red pepper flakes (depending on how spicy you want it)
  • 24 oz. marinara sauce (about 2 1/2 cups)
  • 2 tablespoons chopped fresh parsley (optional)
  • olive oil, more parsley, parmesan cheese, black pepper, and more crushed red pepper for serving (optional)


  • Bring a large pot of heavily salted water to a boil and cook linguine according to directions until one minute before al dente.

  • Pat seafood dry with a paper towel. (If using frozen seafood, make sure it’s completely defrosted.)

  • Heat the olive oil (2 tablespoons) in a large deep skillet or pot over medium heat. Add the seafood (16 oz.) and the crushed red pepper (1/2 -1 teaspoon) and sauté until seafood is cooked through, about 5-6 minutes (or if already cooked, heated through, about 3-4 minutes).

  • Add marinara sauce (24 oz.) and parsley (2 tablespoons, if using) to the seafood in the skillet and heat through. If it’s ready before the pasta is done, turn off heat and cover to keep it warm.

  • When pasta is finished cooking to 1 minute before al dente, transfer it directly to the skillet with tongs, as well as 1/2 cup of the pasta cooking water, and toss to coat. Heat for about 1-2 more minutes, until the pasta is finished cooking to al dente and the sauce thickens and coats the pasta well (you can add more pasta water 1/4 cup at a time if it seems dry at all).

  • Serve with an extra drizzle of olive oil, parmesan cheese, parsley, black pepper, and more crushed red pepper if desired.


  • I used a 1-lb. bag of frozen mixed seafood with calamari, shrimp, mussels, and octopus to make this. You can use any kind of seafood you want, cooked or uncooked, fresh or frozen, but fish may flake apart a lot as you make the sauce (shellfish and calamari/octopus are more ideal for this reason). If using frozen, sure it’s defrosted completely by leaving it in the fridge for 24 hours before cooking or by running cool water over the seafood in a colander or soaking in cool water until defrosted.
  • If you want an extra spicy version of this diavolo sauce, try using arrabbiata sauce (which is a spicy marinara sauce) instead of traditional marinara.
  • Seafood linguine fra diavolo is best served right away, but leftovers will stay good (and still taste great reheated) for about 2 days.
  • Some purists out there may argue that parmesan cheese is not traditionally served with seafood. I acknowledge this, and also say do whatever makes you happy (I love parmesan cheese with mine!).
