Creamy Seafood Stuffed Shells
Why I Made This
My sister brought over a bag of frozen shrimp and imitation crab from Costco, saying she’d bought too much and didn’t have freezer space. I had jumbo shells in the pantry from a lasagna phase I went through last month, and the idea of stuffing them with seafood felt more interesting than another baked ziti. It was Sunday afternoon, cold outside, and I wanted something that felt a little fancy but didn’t require me to stand at the stove for an hour. The creamy sauce was because I had ricotta that needed using and heavy cream left from making pasta earlier in the week.
What Happened While Cooking
The shells cooked faster than I expected—I set a timer for eleven minutes but checked at nine and they were already tender enough to stuff. A few split when I drained them, so I cooked a couple extra as backups. When I mixed the filling, it looked too wet at first, and I worried it would leak out during baking. I added more ricotta and some extra Parmesan to thicken it, then let it sit while I made the sauce. The other moment was when I poured the cream sauce into the baking dish—it pooled more than I wanted, and I had to spoon some out so the shells wouldn’t drown.
Ingredient Notes
I used imitation crab because that’s what my sister brought, and honestly it worked fine here—the cream and cheese mellow out the flavor enough that you don’t need real crab. The shrimp I chopped into small pieces so they’d mix evenly into the filling and cook through in the oven. I thought about using mascarpone instead of ricotta for a richer filling, but ricotta has that slight graininess that I actually like in stuffed shells. The mozzarella on top was low-moisture because fresh mozzarella would’ve made everything too watery. I added a pinch of Old Bay to the filling because seafood and Old Bay just go together, and I used about half a teaspoon.
Step-by-Step Cooking Experience
I brought a large pot of salted water to a boil and added the jumbo shells, stirring once so they wouldn’t stick. While they cooked, I chopped the shrimp into bite-sized pieces and shredded the imitation crab with my fingers. In a bowl, I mixed the ricotta, shredded mozzarella, a beaten egg, the seafood, minced garlic, Old Bay, salt, and pepper. The filling smelled briny and garlicky, and it was thick enough to hold on a spoon after I adjusted it.
I drained the shells and ran cold water over them so I could handle them, then laid them out on a clean towel. For the sauce, I melted butter in a saucepan, whisked in flour, and cooked it for a minute until it smelled toasty. I poured in the heavy cream slowly, whisking the whole time, and it thickened as it simmered. I added Parmesan, a squeeze of lemon juice, and a little white wine I had open. The sauce tasted rich and slightly tangy.
I spread a thin layer of sauce in the bottom of a baking dish, then stuffed each shell with a spoonful of the seafood mixture. They were slippery and a few of the shells tore, but most held together. I arranged them in the dish, poured the remaining sauce over the top—then realized it was too much and scooped some back out. I sprinkled more mozzarella on top and covered the dish with foil.
I baked it at 375°F for twenty-five minutes, then pulled off the foil and baked another ten minutes until the cheese browned in spots. The kitchen smelled like garlic and the sea.
Mistakes & Fixes
I should’ve drained the shrimp better before adding them to the filling—they released a little water, which is why the mixture was loose at first. Patting them dry with a paper towel would’ve helped. The other thing is I poured too much sauce into the dish without thinking, and it made the bottom shells a little soupy. Next time I’ll use about three-quarters of the sauce and serve the rest on the side.
Serving & Leftovers
I served it with garlic bread and a simple salad, and my husband ate three shells immediately. My sister came back over for dinner and said it tasted like something from a restaurant, which felt like a win. We had six shells left, and I stored them in the fridge in the same baking dish covered with plastic wrap. The next day I reheated two shells in the microwave for lunch, and they were fine but not as creamy—the sauce had thickened up. Reheating in the oven at a low temperature worked better on day three.
Closing
I’d make this again if I had seafood to use up, though I might try real crab or even lobster if I’m feeling ambitious.

- 24 jumbo pasta shells (about 12 oz)
- 8 oz lump crab meat, drained and picked over
- 8 oz cooked small shrimp, chopped
- 15 oz whole milk ricotta cheese
- 1 cup shredded mozzarella cheese, divided
- ½ cup grated Parmesan cheese, divided
- 1 large egg
- 2 tbsp fresh parsley, chopped
- 1 tsp lemon zest
- 1 tbsp lemon juice
- ½ tsp salt
- ¼ tsp black pepper
- ¼ tsp Old Bay seasoning (optional)
- ¼ cup unsalted butter
- 3 cloves garlic, minced
- 1½ cups heavy cream
- 1 cup chicken or seafood broth
- 1 cup grated Parmesan cheese
- ¼ tsp nutmeg
list Instructions
- Cook Pasta Shells: Bring a large pot of salted water to a boil. Cook jumbo shells according to package directions until al dente (usually 9-11 minutes). Drain and rinse with cool water to stop cooking. Arrange shells in a single layer on a baking sheet to prevent sticking.
- Prepare Filling: In a large bowl, combine crab meat, chopped shrimp, ricotta, ½ cup mozzarella, ¼ cup Parmesan, egg, parsley, lemon zest, lemon juice, salt, pepper, and Old Bay (if using). Mix gently until well combined.
- Make Alfredo Sauce: In a medium saucepan, melt butter over medium heat. Add garlic and cook for 1 minute until fragrant. Pour in heavy cream and broth, whisking to combine. Bring to a simmer, then reduce heat to low. Stir in Parmesan and nutmeg until cheese is melted and sauce is smooth. Remove from heat.
- Assemble: Spread ½ cup of the Alfredo sauce in the bottom of a 9×13 inch baking dish. Using a spoon or piping bag, fill each pasta shell with the seafood mixture (about 2 tablespoons per shell). Arrange stuffed shells in the baking dish in a single layer.
- Add Sauce & Cheese: Pour remaining Alfredo sauce evenly over the stuffed shells. Sprinkle with remaining ½ cup mozzarella and ¼ cup Parmesan cheese.
- Bake: Cover dish with foil and bake at 375°F (190°C) for 20 minutes. Remove foil and bake uncovered for an additional 10-15 minutes, until cheese is golden and sauce is bubbly.
- Rest & Serve: Let the stuffed shells rest for 5-10 minutes before serving. This allows the filling to set slightly. Garnish with additional chopped parsley and lemon wedges if desired.

lightbulb Success Tips & Variations
- Don’t overcook shells: Cook shells just until al dente—they’ll continue cooking in the oven. Overcooked shells tear easily when stuffing.
- Check crab for shells: Gently go through crab meat with your fingers to remove any small shell fragments before mixing.
- Use a piping bag: For neat, easy stuffing, transfer filling to a large plastic bag, snip off a corner, and pipe into shells.
- Make ahead: Assemble stuffed shells up to a day in advance. Cover and refrigerate until ready to bake. Add 5-10 minutes to baking time if cold.
- Seafood variations: Substitute with cooked lobster, scallops, or imitation crab. You can also use all shrimp or all crab.
- Lighter option: Use part-skim ricotta and replace half the heavy cream in the sauce with milk. The sauce will be thinner but still delicious.
package Storage & Reheating
Storage: Cool completely and store in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze unbaked stuffed shells (without sauce on top) for up to 1 month.
Reheating: Reheat individual portions in the microwave at medium power for 2-3 minutes. For larger portions, cover with foil and bake at 350°F (175°C) for 15-20 minutes until heated through.
Freezing: To freeze, assemble shells in a freezer-safe dish without the final cheese topping. Wrap tightly. Thaw overnight in refrigerator before baking as directed, adding extra baking time as needed.
