How to Make Shrimp Crab Alfredo Bake Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F and lightly greasing a 9×13-inch baking dish. This ensures a non-stick surface and helps the bake cook evenly while letting the flavors meld beautifully.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil and cook your pasta according to the package directions until al dente. This helps it keep a bit of bite and prevents mushiness once baked. Drain and set aside while you prepare the sauce and seafood.
Step 3: Sauté Garlic and Shrimp
In a large skillet over medium heat, melt the butter until foaming. Add the minced garlic and sauté for about one minute until fragrant—it’s the aroma that really starts to wake up the senses! Then add the shrimp, cooking them for 2–3 minutes per side just until pink and opaque. Remove the shrimp from the skillet and set aside to keep them tender and juicy.
Step 4: Create the Alfredo Sauce
Using the same skillet, pour in the heavy cream and bring it to a gentle simmer. Stir in Parmesan cheese, salt, black pepper, and Old Bay seasoning if you’re using it. Let this sauce cook for 3–4 minutes, stirring frequently until it thickens slightly, creating that signature rich and creamy texture we all cherish.
Step 5: Combine Pasta, Seafood, and Sauce
Add the cooked pasta, shrimp, and delicate lump crab meat into the skillet with your Alfredo sauce. Gently fold everything together to coat all the ingredients evenly without breaking up the tender crab. This harmony of textures is what makes the Shrimp Crab Alfredo Bake Recipe truly memorable.
Step 6: Assemble and Bake
Transfer the creamy seafood and pasta mixture into your greased baking dish. Evenly sprinkle half of the shredded mozzarella cheese over the top. Pop the dish into your preheated oven and bake for 15–20 minutes until everything is heated through and bubbling with cheesy goodness. If you’re craving a golden, crispy top, broil for an additional 1–2 minutes—just keep a close eye to avoid burning.
Step 7: Garnish and Serve
Once out of the oven, sprinkle the freshly chopped parsley over the top for a burst of color and herbal brightness. Serve warm and watch everyone dive in, savoring every creamy, seafood-packed bite.
How to Serve Shrimp Crab Alfredo Bake Recipe

Garnishes
Brighten your dish with freshly chopped parsley as the perfect herbaceous finish. If you want an extra touch, a squeeze of lemon juice or a sprinkle of grated Parmesan right before serving can bring out the flavors even more.
Side Dishes
This rich, creamy bake pairs beautifully with light, crisp sides like a green salad with tangy vinaigrette or garlic roasted asparagus. A crusty baguette also works wonders to soak up any leftover sauce on the plate.
Creative Ways to Present
For a fun twist, try serving individual portions in small ramekins or mini cast iron skillets topped with melted mozzarella. You can also present the bake atop a bed of sautéed spinach or with a few roasted cherry tomatoes for extra color and a pop of freshness.
Make Ahead and Storage
Storing Leftovers
Store any uneaten Shrimp Crab Alfredo Bake Recipe in an airtight container in the refrigerator for up to 3 days. Make sure to cool the dish completely before refrigerating to keep the sauce from separating.
Freezing
This bake freezes quite well! For best results, assemble but do not bake. Wrap tightly with foil and plastic wrap and freeze for up to 2 months. When ready, thaw overnight in the refrigerator, then bake as directed.
Reheating
Reheat leftovers in the oven at 350°F until warmed through, about 15–20 minutes. Cover with foil to prevent drying out and remove the foil during the last few minutes if you want to refresh the melty cheese topping.
FAQs
Can I use frozen shrimp for the Shrimp Crab Alfredo Bake Recipe?
Absolutely! Just be sure to thaw the shrimp thoroughly and pat them dry before cooking to avoid excess moisture that could thin the sauce.
Is it possible to make this recipe dairy-free?
You can substitute heavy cream with coconut cream and use dairy-free cheese alternatives, but keep in mind the flavor and texture will be different from the traditional rich Alfredo taste.
Can I add other seafood to this bake?
Yes! Scallops, lobster chunks, or even crab claws can be wonderful additions. Just adjust cooking times to ensure all seafood is perfectly cooked without overdoing it.
What pasta works best for this recipe?
Fettuccine and penne are both excellent because their shapes hold the creamy sauce well, but rigatoni, rotini, or even shells would be delicious alternatives.
How can I make the dish spicier?
Incorporate red pepper flakes into the sauce or sprinkle a dash of Cajun seasoning on the shrimp before cooking for a flavorful kick.
