Equipment

  • large heavy skillet (12-inch minimum)

Ingredients

  • 1 pound mixed seafood, thawed if purchased frozen (Mixed seafood usually includes shrimp, scallops, mussels and calamari)
  • ¼ cup olive oil
  • 1 onion, diced
  • 2 teaspoons red chili flakes Use less for a milder sauce
  • ¼ teaspoon sea salt
  • 4 garlic cloves, diced
  • 2 pounds fresh tomatoes (diced) or 28oz can diced or crushed tomatoes
  • 1 cup water
  • 1 teaspoon dried oregano
  • ½ pound spaghetti Use gluten-free spaghetti if needed

Instructions

Fra Diavolo Sauce:

  • Add the oil, onions, chili flakes and salt to a large, shallow pan. (Use a 12" pan or larger, see recipe notes.) Cook the onions over medium heat until they begin to brown (~5 min).
    Add the garlic and cook 1 more minute, or until the garlic is fragrant.
    Cook Onions, Peppers + Garlic in Oil
  • Add the tomatoes, water, and oregano to the pan. Increase the heat to medium-high and bring to a simmer.
    Add Tomatoes, Water + Oregano
  • Simmer the tomatoes for 20-25 minutes, or until most of the water has evaporated and the sauce has thickened.
    Taste the sauce and add more chili flakes, salt, or oregano if desired. Simmer 1-2 more minutes if you added more seasoning.
    Simmer Fra Diavolo Sauce Until Thickened
  • While the sauce simmers, bring a large pot of salted water to a rolling boil. Add the mixed seafood and cook for about 2 minutes. (If the seafood mix includes shrimp, cook until the shrimp turn pink.)
    Use a mesh sieve, skimmer or slotted spoon to remove the seafood from the water into a colander. Rinse with cold water to stop the seafood from cooking. Place the seafood in the fridge until your sauce is ready.
    (Do not discard the hot water.)

Notes

Serves: This serves two people generously.  For more modest portions, store half the pasta sauce for later and use ¼ lb. spaghetti.
Pan Size: Some readers have reported that their 12″ pans were too small for the volume of sauce. You may find a heavy Dutch oven works best for you, although I’ve always had success with my 12″ carbon steel pan.
Prepare Ahead: The sauce can be prepared ahead of time and refrigerated for 4-6 days, or frozen and used within a year.
Smoother Sauce with Fresh Tomatoes: Canned tomatoes are peeled, and will yield a smoother sauce with less texture.  If you’re using fresh tomatoes and want an extra-smooth marinara, you have two options:
1.  Peel the tomatoes first.  Use a knife to mark an X on each tomato, and then blanch them in boiling water until the tomato peel loosens (~15-30 seconds).  Peel, and then proceed with the recipe.  Crush tomatoes with your hands instead of dicing.
or
2. Blend the sauce.  After cooking, add the sauce to a blender or use an immersion blender to blend the peels into the sauce.
Varieties of tomatoes: For the thickest sauce, use San Marzano tomatoes (or other varieties of Roma tomatoes).  However, this recipe works well with juicy tomatoes also.
