Instructions

  1. Bring a large pot of salted water to a boil. Meanwhile, wash and dry all produce. Core, deseed and thinly slice the long green pepper. Halve, peel and thinly slice the shallot. Mince the garlic.
  2. Once the water is boiling, add the penne and cook until al dente, 9-11 minutes. Drain and set aside.
  3. Rinse the shrimp and pat very dry with paper towels. Place in a medium bowl and toss with a drizzle of olive oil, half the oregano, salt and pepper. Heat a large nonstick pan over medium-high heat. Add the shrimp and cook, stirring occasionally, until opaque and cooked through, 3-4 minutes. Transfer to a plate.
  4. In the same pan, heat a drizzle of olive oil over medium-high heat. Add the sliced green pepper, shallot and a pinch of salt. Cook, stirring occasionally, until slightly softened, about 5 minutes. Stir in the garlic, remaining oregano and ¼ teaspoon chili flakes (adjust to taste). Cook until fragrant, 30 seconds to 1 minute.
  5. Stir in the diced tomatoes (with their juices), seafood stock concentrate and ½ teaspoon salt. Bring to a boil, then reduce heat to medium and simmer until the sauce thickens slightly, 5-7 minutes. Add the cooked shrimp, drained penne and butter; stir until the butter melts and everything is well combined. Taste and adjust seasoning with salt. For extra heat, add more chili flakes.
  6. Divide the pasta among bowls. Sprinkle with additional chili flakes if desired.

Recipe Tips

For a milder dish, reduce or omit the chili flakes. For extra heat, add more at the end.

Pat the shrimp very dry before cooking to ensure they sear properly and don’t steam.

If you don’t have seafood stock concentrate, substitute with ½ cup fish or chicken broth and reduce the added salt.

FAQ

Can I use a different type of pasta?

Yes, any short pasta like rigatoni, fusilli or farfalle works well. Adjust cooking time according to package directions.

Can I substitute the shrimp with chicken or tofu?

Absolutely. For chicken, use boneless skinless thighs or breasts, cut into bite-sized pieces and cook until no longer pink. For tofu, use extra-firm, cubed and pan-fry until golden.

How do I store leftovers?

Store in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave, adding a splash of water if needed.
