Garlic Shrimp Alfredo Bake with Creamy Parmesan Sauce

This Garlicky Shrimp Alfredo Bake is my go-to for using up leftover shrimp from a shrimp boil or a meal out. Rich, creamy, cheesy and packed with garlic, I usually make it with fettuccine—friends often call it shrimp fettuccine. Whatever you call it, it’s delicious.

Shrimp Alfredo

Shrimp season makes this dish especially popular at my house. We often boil shrimp and then have just enough left over to turn into this creamy bake. Shrimp seasons vary by region—for example, in Louisiana the season often runs from May to December, with different species available at different times.

  • Step 1: Cook pasta to al dente according to package directions. Drain, reserving 1 cup of pasta water, and set aside.
  • Step 2: Heat olive oil in a large, oven-safe skillet over medium–medium-high heat.
  • Step 3: If using raw shrimp, sear briefly on each side until just cooked; remove and set aside. Add onions, garlic and parsley to the skillet and cook until softened and fragrant.
  • Step 4: Add butter, cream cheese, red pepper flakes, salt and pepper, then pour in heavy cream. Stir and bring to a gentle simmer.

  • Step 5: Stir in grated Parmesan until the sauce is smooth.
  • Step 6: Add the cooked pasta and shrimp (or cooked shrimp) to the sauce and toss to coat evenly.
  • Step 7: Top with grated mozzarella, spreading it evenly.
  • Step 8: Place the skillet under a broiler for a few minutes until the top is golden and bubbly.

Hint: Save a cup of pasta water when draining. If the alfredo sauce becomes too thick, add a little pasta water to reach the desired consistency.

Recipe variations and substitute ideas

  • Crawfish – swap shrimp for crawfish for a Louisiana twist.
  • Sour cream – use sour cream in place of cream cheese for a tangier sauce.
  • Penne or spaghetti – any pasta shape works well, switch to your favorite.
  • Vegetarian – omit the shrimp for a simple cheesy pasta bake.
  • Chicken – cooked diced chicken makes a great alternative protein.
  • Spicy – increase red pepper flakes for more heat.
  • Extra garlic – a pinch of garlic powder boosts garlic flavor differently than fresh garlic.
  • Deluxe – add lump crab meat for a special treat.
  • Kid friendly – skip red pepper flakes for a milder dish.

Necessary gear: Equipment

I prefer using a cast iron skillet for this recipe because it sears and broils beautifully and adds even heat. Any oven-safe skillet will work.

A whisk or wooden spoon is useful for stirring the sauce.

How to store leftovers

Let the bake cool completely, then transfer to an airtight container and refrigerate for up to 3 days.

Reheat gently on the stove or in the microwave, adding a splash of milk or reserved pasta water if the sauce has thickened.

Mel’s kitchen notes

If you want extra flavor, simmer shrimp shells in water for 30 minutes to make a quick shell stock, then cook the pasta in that water. It adds a subtle seafood depth to the dish.

What to serve with Shrimp Alfredo

A simple dipping sauce like a buttery Cajun sauce pairs nicely, and crusty bread is perfect for mopping up the sauce. Garlic butter rolls, stuffed garlic bread or a garlic monkey bread are all excellent companion breads to serve alongside.
