Cut into a hot roll-up and the center opens to pink shrimp, sweet crab, and soft ricotta under browned mozzarella. Shrimp and Crab Alfredo Lasagna Roll Ups bring tender noodles, garlicky glossy Alfredo, and edges that catch just enough heat to turn savory and golden.
Give yourself about 55 minutes total. Most of the work happens before the dish reaches the oven: boiling the noodles, making the sauce, mixing the filling, and rolling everything into the pan.
Why You’ll Love Shrimp and Crab Alfredo Lasagna Roll Ups
Alfredo roll-ups can go wrong when the seafood gets overcooked or the filling carries too much liquid. This version keeps both problems in check while still giving you plenty of creamy sauce and browned cheese.
The shrimp is cut into bite-size pieces and cooked briefly, so it stays visible and tender through the final bake.
A milk-based Alfredo thickened with a small roux coats the noodles without becoming heavy or greasy.
Lump crab adds sweet, delicate seafood flavor without needing a separate sauce or topping.
Eight noodles fit neatly in a 9×13-inch dish, making the portions easy to divide and the pan easy to scale.
The roll-ups hold well overnight, and the garlic-Parmesan flavor settles into the sauce as the leftovers rest.
The uncovered finish gives the mozzarella color while the foil-covered bake keeps the noodles from drying out.
How to Make Shrimp and Crab Alfredo Lasagna Roll Ups
Active prep takes about 25 minutes. The move that matters most is taking the Alfredo off the heat before adding Parmesan, which helps keep the sauce smooth.
The shrimp should be pink and opaque but not firm and rubbery before it goes into the filling. It will finish cooking in the oven.
1. Heat the oven to 375°F. Boil the regular lasagna noodles until flexible but still slightly firm, then drain and lay them flat.
2. Pat the shrimp dry and sauté it in 1 tablespoon of butter for 2 to 3 minutes. Let it cool briefly before mixing it with the crab.
3. Stir together the ricotta, egg, Parmesan, parsley, lemon juice, and seasonings. Fold in the cooled seafood gently so the crab keeps some texture.
4. Make the Alfredo by cooking garlic in the remaining butter, whisking in flour, then gradually adding the milk and half-and-half. Simmer until the sauce coats a spoon but still pours easily, then remove it from the heat and add the Parmesan.
5. Spread sauce in the dish, fill and roll the noodles, and arrange them seam-side down. Cover with the remaining sauce and mozzarella, bake covered for 15 minutes, then uncovered for 10 minutes. Rest 5 minutes before serving.
Storing and Reheating Tips
The sauce firms up in the refrigerator, and the noodles soften slightly, but the flavor deepens overnight. Keep leftovers refrigerated for up to 3 days, or freeze baked portions for longer storage.
Let the roll-ups cool before sealing them in an airtight container. Store them with plenty of sauce so the noodles don’t dry out.
For make-ahead prep, assemble the pan up to 1 day ahead and refrigerate it covered. Starting with a cold dish usually requires about 10 extra minutes under the foil.
Freeze baked portions for up to 1 month. Thaw them overnight in the refrigerator because frozen Alfredo can separate if reheated too aggressively.
Reheat larger portions in a covered 325°F oven until the center is hot and the sauce loosens. Add a spoonful of milk if the edges look dry.
For one portion, use the microwave at 50 percent power in short bursts. Keep it covered and stop as soon as the center is hot.
Variations and Substitutions
The seafood filling has some room to move, but keep the bite-size shrimp and pourable Alfredo sauce anchored. Those two details give the roll-ups their structure and prevent the filling from feeling loose.
Medium shrimp work well as long as you cut them into bite-size pieces. Large whole shrimp make the rolls bulky and take longer to heat through.
Pre-cooked shrimp can be used in a pinch. Cut it into pieces and fold it into the filling without sautéing, but expect a slightly softer texture.
Canned lump crabmeat is a practical substitute for fresh crab. Drain it thoroughly and pick through it for shell pieces before adding it to the ricotta mixture.
Replace the half-and-half with an equal amount of whole milk for a lighter sauce. Simmer it a little longer if it seems too loose.
Regular noodles are the safest choice here. Oven-ready noodles need different liquid and can leave the center chewy when used like boiled noodles.
For more heat, increase the red pepper flakes. Keep the lemon juice and parsley in place because they cut through the rich Alfredo.
Ingredient Notes
Each ingredient has a specific job in this pan. The shrimp brings the visible seafood texture, while the ricotta, egg, and Parmesan hold the filling together without making it dense.
Start with peeled, deveined shrimp and cut it into bite-size pieces. Smaller pieces distribute evenly and finish cooking quickly.
Lump crabmeat should be drained and gently flaked. Pressing out excess liquid keeps the filling from watering down the sauce.
Regular lasagna noodles roll more easily than oven-ready noodles. Cook them just until flexible, then lay them flat so they don’t dry or stick together.
Ricotta gives the filling a soft, creamy center, while the egg helps it set during baking. Whole-milk ricotta gives the smoothest texture.
Finely grated Parmesan melts more evenly into the Alfredo. The milk and half-and-half keep the sauce pourable, while flour gives it enough body to cling to the noodles.
Garlic, lemon juice, parsley, and red pepper flakes keep the seafood from disappearing under the dairy. Hold back some parsley for the finished pan so the top looks fresh.
Expert Cooking Tips
The most common miss is overcooking the seafood before the pan even reaches the oven. The shrimp only needs a short skillet cook, and the crab should be folded in gently.
Don’t do this: cook the shrimp until fully firm in the skillet. Pink and opaque is enough; the covered bake finishes the center without making it rubbery.
Add the Parmesan after removing the sauce from the heat. If the sauce turns grainy, return it to very low heat and whisk in a tablespoon of milk.
Keep a layer of sauce under the noodles and cover the dish for the first 15 minutes. That combination protects the bottom edges from drying out.
Roll the noodles with an even layer of filling rather than a thick mound. An overfilled roll splits and leaves less room for sauce between the pieces.
Arrange every roll seam-side down. If one opens during baking, add a little extra sauce over that spot and it will still hold together.
Let the pan rest for 5 minutes before serving. The filling settles, the sauce thickens slightly, and the rolls lift out more cleanly.
What to Serve with Shrimp and Crab Alfredo Lasagna Roll Ups
For shrimp Alfredo sides, choose something crisp, green, or lightly acidic. The roll-ups already bring pasta, dairy, and seafood, so the best pairings should refresh the plate rather than add another heavy component.
A romaine salad with lemon vinaigrette cuts through the creamy sauce and adds crunch.
Steamed broccoli or green beans gives the meal a fresh vegetable component without competing with the crab.
Roasted cherry tomatoes bring acidity and a little sweetness that works well with garlic and Parmesan.
A small piece of toasted garlic bread is useful for catching the sauce, especially when the pan has plenty left around the edges.
For a lighter lunch plate, serve one roll-up with cucumber salad and a squeeze of lemon.
FAQ
Most questions about this recipe come down to seafood doneness, make-ahead timing, and keeping the filling from getting watery.
1. Can I assemble the roll-ups ahead?
Yes. Assemble the dish up to 1 day ahead, cover it, and refrigerate. Add about 10 minutes to the covered bake when starting with a cold pan.
2. How do I know the shrimp are done?
The pieces should be pink, opaque, and just firm in the center. They should not look translucent, but cooking them until hard in the skillet will leave them rubbery after baking.
3. Can I freeze baked portions?
Yes, for up to 1 month. Thaw overnight in the refrigerator and reheat covered so the Alfredo doesn’t dry out.
4. Why is my filling watery?
The crab may not have been drained well, or the shrimp may have released excess moisture. Drain the crab thoroughly and pat the shrimp dry before cooking.
5. Can I use oven-ready noodles?
Regular noodles work better for this version. Oven-ready noodles need more liquid and may stay chewy around the center of each roll.
