Ingredients You’ll Need

It’s important to use high-quality fresh ingredients for maximum flavor in this shrimp Alfredo bake.

  • Penne Pasta (12 oz): Holds up well to baking and soaks up the sauce.
  • Butter (3 tbsp, divided): The base for the Alfredo sauce and key to sautéing.
  • Garlic (3 cloves, minced): Adds depth and classic flavor.
  • Shrimp (1 lb, peeled and deveined): Medium or large preferred; quick-cooking and sweet.
  • Fresh Parsley (2 tbsp, chopped, plus more to garnish): Lifts the flavor and color.
  • Kosher Salt: Enhances all the flavors.
  • All-Purpose Flour (2 tbsp): For thickening the sauce.
  • Milk (3/4 cup, preferably whole or 2%): Creamy, but slightly lighter than using all cream.
  • Low-Sodium Chicken Broth (1/4 cup): Adds subtle savory depth.
  • Mozzarella Cheese (1 cup, shredded, divided): For stretch and melting.
  • Parmesan Cheese (1/4 cup plus 2 tbsp, grated, divided): Savory, nutty, and the classic Alfredo must-have.
  • Ground Black Pepper: For subtle heat.
  • Tomatoes (1 cup, chopped, about 2 large): Juicy bursts of brightness to offset the creamy sauce.

Ingredient Substitutions

  • Pasta: Swap penne for rigatoni, ziti, or even fettuccine.
  • Shrimp: Try chicken, scallops, or omit for a vegetarian version.
  • Milk: Use half-and-half for a richer sauce, or lactose-free milk as needed.
  • Cheese: Add Gruyère or Fontina for a different cheesy profile.

Step-By-Step Instructions

This Alfredo bake is easy to assemble, making it suitable for both beginners and experienced cooks.

  1. Cook the Pasta
    • Preheat your oven to 350°F (175°C).
    • Bring a large pot of salted water to boil. Add the penne and cook until just al dente, according to package instructions.
    • Drain the pasta, reserving a small cup of the pasta water (just in case your sauce needs to be thinned later).
  2. Sauté the Shrimp
    • In a large oven-safe skillet over medium heat, melt 1 tablespoon of the butter.
    • Add the minced garlic, shrimp, and half your chopped parsley; season with salt.
    • Cook shrimp for about 2 minutes per side until pink and opaque. Transfer shrimp to a plate. Keep any juices in the skillet.
  3. Make the Alfredo Sauce
    • Add the remaining 2 tablespoons of butter to the skillet and melt.
    • Stir in the flour and whisk until golden and slightly nutty-smelling, about 1 to 2 minutes.
    • Slowly pour in the milk and chicken broth, continuing to whisk smooth. Bring to a simmer.
    • Stir in 3/4 cup shredded mozzarella and 1/4 cup grated Parmesan until fully melted and sauce is creamy. Season with salt and pepper to taste.
  4. Combine and Bake
    • Return the shrimp (plus any juices) to the skillet. Add the chopped tomatoes and cooked pasta; toss to coat everything in sauce. If needed, add a splash of your reserved pasta water to loosen.
    • Top evenly with the remaining mozzarella and Parmesan.
    • Bake in the preheated oven for 5 to 7 minutes, or until the cheese is melty and bubbling.
    • Turn on the broiler for 2 to 3 minutes; broil until the top is golden (watch closely to avoid burning!).
  5. Garnish and Serve
    • Sprinkle with the rest of your fresh parsley before serving for a pop of color and flavor.

Tips for Perfect Shrimp

  • Don’t overcook: Shrimp cook quickly (about 2 minutes per side). Overcooked shrimp will become rubbery.
  • Season well: Even a little salt and parsley helps bring out the natural sweetness.
  • Freshness counts: Use fresh or well-thawed shrimp, peeled and deveined for the best texture.
  • Leave tails on or off: Tails add visual appeal, but removing them before baking makes eating easier.

Customizations and Variations

This shrimp Alfredo bake is incredibly versatile. Here are some popular twists to tailor it to your tastes:

  • Vegetable Add-ins: Sautéed spinach, peas, broccoli, or asparagus can be stirred in before baking.
  • Protein Swaps: Substitute with grilled chicken, pan-seared scallops, or even sausage for a heartier meal.
  • Spicy Kick: Add a pinch of crushed red pepper flakes or a touch of Cajun seasoning for heat.
  • Cheese Layering: Mix in cream cheese for extra richness or use a blend of Italian cheeses for more complexity.
  • Low-Carb Alternative: Use cauliflower florets or zucchini noodles instead of pasta for a lower-carb option.

Serving Suggestions

Elevate your shrimp Alfredo bake into a complete meal with these classic pairings:

  • Garlic Bread: Perfect for scooping up extra sauce.
  • Crisp Green Salad: Mixed greens with a light vinaigrette help balance the creamy pasta.
  • Roasted Veggies: Oven-roasted asparagus, broccoli, or bell peppers for added nutrition.
  • Wine Pairings: A chilled Pinot Grigio or Sauvignon Blanc complements the richness of Alfredo sauce.

Storing and Reheating

  • Refrigerate: Place cooled leftovers in an airtight container and refrigerate up to 3 days.
  • Reheat: Warm individual portions in the microwave or heat in a 350°F (175°C) oven, covered, until bubbling. Add a splash of milk or cream if sauce thickens during storage.
  • Freeze: Not recommended, as the dairy-based sauce may separate when thawed.

Frequently Asked Questions (FAQs)

Q: Can I make Shrimp Alfredo Bake ahead of time?

A: Yes, assemble the bake up to the point of adding cheese on top. Cover tightly and refrigerate for up to 1 day. Bake just before serving; you may need to add 5–10 minutes to the baking time if baking from cold.

Q: What is the best type of shrimp for this recipe?

A: Use medium or large shrimp that are peeled and deveined for the best texture and flavor. Fresh or properly thawed frozen shrimp are both excellent; pat dry before cooking for best browning.

Q: Can I use store-bought Alfredo sauce instead?

A: Absolutely. If in a hurry, substitute 2 cups of your favorite jarred Alfredo sauce in place of the homemade version. For the best results, gently heat and thin with a splash of milk before mixing with pasta and shrimp.

Q: How can I make this lighter?

A: Use 2% milk, reduced-fat cheeses, and add extra vegetables like broccoli or spinach. There is also the option to use whole-wheat or legume-based pasta for added fiber.

Q: The sauce turned out thick—how do I fix it?

A: Stir in a splash of reserved pasta water or milk. Add gradually and mix until you reach the desired creamy consistency.

Q: How do I prevent the shrimp from turning rubbery?

A: Sauté the shrimp very briefly—about 2 minutes per side—until just pink. They’ll finish cooking during the bake, ensuring juicy, tender results.
