Creating this delicious Jamaican Shrimp Pasta is uncomplicated when following these steps:

1. Cook Pasta: In a large pot of salted boiling water, cook the linguine or spaghetti according to package instructions until al dente. Drain and set aside.
2. Sauté Shrimp: In a large skillet, heat olive oil over medium heat. Add the shrimp and cook for about 2-3 minutes until they turn pink. Remove shrimp from the skillet and set aside.
3. Sauté Vegetables: In the same skillet, add garlic and onion. Sauté until translucent, about 2-3 minutes.
4. Add Bell Pepper: Include the sliced bell pepper and cook for another 2 minutes, until slightly tender.
5. Season: Stir in paprika, cayenne pepper, thyme, allspice, salt, and pepper. Mix well.
6. Add Cream: Pour in the heavy cream (or coconut milk) and bring to a simmer. Allow the sauce to thicken slightly for about 2-3 minutes.
7. Combine Ingredients: Add the cooked pasta and shrimp back to the skillet. Toss everything together until well coated in the sauce.
8. Final Adjustments: Stir in optional cherry tomatoes or spinach if using, and cook for an additional minute, just until heated through.
9. Garnish: Remove from heat and garnish with chopped cilantro or parsley before serving.

With these straightforward steps, you will create a mouthwatering Jamaican Shrimp Pasta that is bursting with flavor!
