Step-by-Step Instructions
- Prepare the Shrimp:
- Begin by thoroughly peeling and washing the shrimp then gently pat them dry with paper towels to help them sear better. In a mixing bowl toss the shrimp with fresh lemon juice olive oil Cajun seasoning garlic powder both types of paprika and oregano mixing well until shrimp are evenly coated and glistening.
- Cook the Shrimp:
- Warm a large skillet over medium high heat then swirl in a light coating of oil. Lay the shrimp in without crowding and cook for about one to two minutes per side just until they turn pink and opaque. Promptly remove the shrimp from the skillet and set aside so they do not overcook.
- Sauté the Vegetables:
- Add unsalted butter to the same warm skillet and let it melt. Stir in the diced jalapeño red bell pepper and onion. Let these sauté gently for seven to ten minutes stirring every so often until the vegetables have softened and their aroma intensifies.
- Prepare the Sauce:
- Pour in the tomato sauce stirring it around to deglaze the pan and incorporate any browned bits stuck to the bottom. Let it cook for two to three minutes. Next stir in the heavy cream and the remaining Cajun seasoning garlic powder paprika and oregano. Mix until the sauce is smooth and gently simmering.
- Return the Shrimp and Finish the Sauce:
- Add the cooked shrimp and chopped fresh parsley back into the skillet. Sprinkle in freshly grated Parmesan if desired. Let everything simmer gently for about five minutes. This melds the shrimp into the sauce and allows the flavors to bloom.
- Cook the Pasta:
- Meanwhile cook the rigatoni pasta in a large pot of aggressively salted boiling water. Cook until just al dente following your package instructions. Scoop out a small cup of pasta water before draining which helps with sauce consistency later.
- Combine and Serve:
- Tumble the hot drained pasta into the skillet with the creamy shrimp sauce. Add a generous splash of reserved pasta water and toss everything together allowing the sauce to cling to every noodle. Simmer for another five minutes to thicken and let flavors marry.
- Garnish and Serve:
- Taste the finished dish and tweak with salt and pepper to your preference. Serve hot in bowls garnished with extra Parmesan fresh parsley and a few cracks of black pepper.
