Easy peasy weeknight alfredo made completely from scratch, made in 35 min or less! With the creamiest alfredo sauce ever with perfectly flavored, tender shrimp! This is comfort food at its best (and easiest!).
In a large pot of boiling salted water, cook pasta according to package instructions; drain well.
Preheat oven to broil. Lightly oil a baking sheet or coat with nonstick spray.
Place shrimp in a single layer onto the prepared baking sheet. Add olive oil and paprika; season with salt and pepper, to taste. Gently toss to combine.
Place into oven and broil just until pink, firm and cooked through, about 3-4 minutes. Stir in lemon juice; set aside.
Melt butter in a large skillet over medium heat. Add garlic and red pepper flakes, and cook, stirring frequently, until fragrant, about 1-2 minutes. Whisk in flour until lightly browned, about 1 minute.
Gradually whisk in milk and half and half. Cook, whisking constantly, until thickened, about 2-4 minutes.
Remove from heat. Stir in cheese until melted, about 1-2 minutes. If the mixture is too thick, add more milk as needed; season with salt and pepper, to taste.
Stir in pasta and gently toss to combine.
Serve immediately with shrimp, garnished with parsley, if desired.
Notes
*Half and half is equal parts of whole milk and cream. For 1 cup half and half, you can substitute 3/4 cup whole milk + 1/4 cup heavy cream or 2/3 cup skim or low-fat milk + 1/3 cup heavy cream.
