Step 1: Prepare the Pasta - Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Reserve about 1 cup of pasta water, then drain the pasta and set aside.
Step 2: Sauté the Garlic and Rosemary - In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute, or until fragrant. Stir in the chopped rosemary and salt, cooking for an additional 30 seconds.
Step 3: Cook the Shrimp - Add the peeled and deveined shrimp to the skillet. Cook for about 2-3 minutes on each side until they turn pink and opaque.
Step 4: Combine Pasta and Shrimp - Once the shrimp are cooked, add the drained pasta to the skillet. Toss everything together, adding a little reserved pasta water to loosen the mixture if necessary.
Step 5: Add Lemon Zest and Season - Sprinkle the lemon zest over the pasta and shrimp, mixing well. Season with additional salt and pepper to taste.
Step 6: Serve and Enjoy - Plate the Rosemary Shrimp Pasta immediately, garnishing with extra rosemary if desired.
