Cook the Pasta:
Boil the pasta in a large pot of salted water until al dente (firm to the bite). Reserve ½ cup of pasta water before draining.
Sear the Shrimp:
Season the shrimp with salt, black pepper, and paprika. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Cook the shrimp for 2 minutes per side until pink and opaque. Remove the shrimp from the skillet and set aside.
Sauté Garlic and Bell Peppers:
In the same skillet, melt 2 tablespoons of butter. Add the diced bell pepper and cook for 2–3 minutes until slightly softened, then add the minced garlic and cook for 30–60 seconds until fragrant.
Build the Cream Sauce:
Pour in the heavy cream and lemon juice (plus lemon zest). Let it simmer gently for 2–3 minutes until it thickens slightly.
Add Cheese and Toss:
Stir in the grated Parmesan cheese until melted and smooth. Add the cooked pasta and a splash of the reserved pasta water, tossing to coat every strand.
Combine and Serve:
Nestle the cooked shrimp back into the pasta to warm through for 1 minute. Garnish with fresh parsley and extra Parmesan before serving.
If you'd like, I can give you low-calorie swaps for the heavy cream or suggest a quick side salad to pair with this dish.
