Cook the Pasta:
Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente, about 8-10 minutes. Reserve 1 cup of pasta water, then drain.
Sauté Aromatics:
In a large skillet, heat olive oil over medium heat. Add the onion and sauté for 3-4 minutes until translucent. Stir in garlic and bell pepper, cooking for another 2-3 minutes.
Cook the Shrimp:
Increase the heat to medium-high and add shrimp to the skillet. Season with salt, pepper, and jerk seasoning. Cook for 3-4 minutes until shrimp turn pink and are cooked through.
Make the Sauce:
Pour in coconut milk and lime juice, stirring to combine. Let the mixture simmer for 3-5 minutes to meld flavors. If the sauce is too thick, add reserved pasta water gradually.
Combine:
Add the drained pasta to the skillet, tossing to coat in the creamy sauce. Adjust seasoning as needed.
Serve:
Serve hot, garnished with cilantro and lime wedges on the side for an extra burst of flavor.
