1-First Step: Get everything ready Start by peeling and deveining the shrimp if needed, then pat them dry with a paper towel. This helps them sear instead of steaming in the pan. Cut the broccoli into small florets so they cook evenly, mince the garlic, and measure out the flour, milk, parmesan, salt, and pepper. Cook the pasta shells in salted water until tender, then drain them and set them aside.

2-Second Step: Cook the broccoli Add the broccoli florets and 1/4 cup water to a large skillet over medium heat. Cover the pan and let the broccoli steam for 3 to 4 minutes, just until it turns bright green and is tender but still has some bite. Remove the broccoli from the skillet and set it aside. This keeps the broccoli from overcooking later.

3-Third Step: Sauté the shrimp Wipe out the skillet if needed, then add 2 tablespoons olive oil over medium-high heat. Place the shrimp in the pan in a single layer. Cook for about 2 minutes per side, or until the shrimp turn pink and opaque. Do not cook them too long or they can turn rubbery. Transfer the shrimp to a plate once done.

4-Fourth Step: Build the Alfredo sauce Turn the heat down to medium and add 3 tablespoons butter to the skillet. Once it melts, stir in the minced garlic and cook for about 30 seconds until fragrant. Sprinkle in the flour and stir for 1 minute to cook out the raw flour taste. Slowly whisk in the milk, a little at a time, so the sauce stays smooth. Keep stirring as it thickens, which usually takes 3 to 5 minutes.

5-Fifth Step: Add the cheese and seasonings Reduce the heat to low and stir in the shredded parmesan cheese. Add 1 teaspoon salt first, then taste the sauce and add more if needed. Stir in the black pepper. If you are using half and half or heavy cream, the sauce will look even richer and thicker. Keep the heat low so the cheese melts smoothly instead of clumping.

6-Sixth Step: Combine the pasta, shrimp, and broccoli Add the drained pasta shells to the sauce and toss until every shell is coated. Gently fold in the cooked shrimp and broccoli. Let everything warm through for 1 to 2 minutes, stirring softly so the shrimp stay tender and the broccoli keeps its color. If the sauce feels too thick, add a splash of milk or a spoonful of pasta water to loosen it.

7-Final Step: Serve and top Spoon the Broccoli Shrimp Alfredo into warm bowls and finish with extra grated parmesan cheese on top. Serve it right away while the sauce is creamy and smooth. This dish is perfect with garlic bread, a crisp salad, or simple roasted vegetables on the side.
