Instructions
 

Cooking the Pasta

  • Cook pasta in generously salted water until just shy of al dente. Reserve 1 cup of pasta water, then drain.

Cooking the Shrimp

  • Season the shrimp with Cajun seasoning and a pinch of salt if needed.
  • Heat a large skillet with olive oil and butter over medium-high heat.
  • Sear shrimp for 1 to 2 minutes per side until pink and just cooked, then transfer to a plate.

Making the Sauce

  • Lower the heat to medium and add more oil if the pan is dry. Cook onion and bell pepper with a pinch of salt until soft, about 4 minutes.
  • Stir in garlic for 30 seconds until fragrant.
  • Add tomato paste and a sprinkle of Cajun seasoning. Toast for a minute until it turns brick red.
  • Pour in heavy cream and bring to a gentle simmer while stirring. If too thick, loosen with reserved pasta water.
  • Taste the sauce and adjust seasoning as necessary.

Combining Ingredients

  • Add the drained pasta to the sauce and toss to combine. Let simmer for 1 minute.
  • Slide the shrimp back in with any juices. Squeeze in lemon juice and toss again. Finish with parsley or green onion and Parmesan if desired.
  • Serve hot with extra lemon on the side.

Note

For seafood swaps, you can use scallops, crab, or firm white fish. If using pre-cooked shrimp, warm it at the end but skip the sear. Store leftovers in a sealed container for up to 2 days. Reheat gently.
