Creamy Shrimp Lasagna
A rich, velvety white-sauce lasagna packed with tender, garlic-butter sautéed shrimp, fresh herbs, and a bubbly golden cheese crust.
- Searing the shrimp first prevents them from releasing excess water during the bake, keeping the lasagna structurally intact.
- A starch-gelatinized BĂ©chamel sauce clings to the lasagna noodles and suspends the seafood beautifully without breaking.
- Fresh lemon zest and chopped dill cut through the rich mozzarella and parmesan layers, balancing the heavy fats.
I still remember the humid Tuesday evening I tried to make a seafood lasagna for my sister's birthday, only to end up with a watery, rubbery disaster that slid off the plate like a sad, lukewarm puddle.
My mistake was treating delicate shrimp like ground beef, letting them boil to death in a heavy, store-bought marinara.
It was tragic.
Bear with me here: shrimp are mostly water and protein. When you bake them raw inside a heavy lasagna, those proteins contract violently, squeezing out moisture and turning your beautiful creamy cheese sauce into a watery soup while the shrimp themselves turn into rubber erasers.
The fix is surprisingly simple: we quick-sear the shrimp in garlic butter first, pull them out while they are still slightly underdone, and build a rich, starch-stabilized white sauce to lock in that moisture.
This ensures every single bite is velvety, structurally sound, and absolutely packed with sweet, garlicky seafood flavor.
Creamy Shrimp Lasagna
Ingredients
- 9 lasagna noodles (oven-ready or boiled al dente)
- 1.5 lbs medium shrimp, peeled, deveined, and chopped into bite-sized pieces
- 1 tbsp olive oil
- 4 tbsp unsalted butter, divided
- 4 cloves garlic, minced
- 1/4 cup all-purpose flour
- 2.5 cups whole milk, warmed
- 1 cup heavy cream
- 1/4 tsp freshly grated nutmeg
- 1.5 tsp Diamond Crystal kosher salt
- 1/2 tsp freshly cracked black pepper
- 1 tbsp fresh lemon juice
- 1 tsp lemon zest
- 2 cups low-moisture mozzarella cheese, shredded and divided
- 1 cup Parmigiano-Reggiano, freshly grated and divided
- 1/2 cup ricotta cheese
- 2 tbsp fresh flat-leaf parsley, finely chopped
- 1 tbsp fresh dill, finely chopped
Directions
- Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with butter or cooking spray.
- Heat the olive oil and 1 tablespoon of butter in a large skillet over medium-high heat. Add the chopped shrimp and cook for just 1 to 2 minutes until they turn pink but are still slightly translucent in the center; transfer them to a bowl using a slotted spoon, leaving the juices behind.
- Melt the remaining 3 tablespoons of butter in the same skillet over medium heat, then whisk in the flour to form a paste (roux) and cook for 1 minute to remove the raw flour taste.
- Slowly pour in the warm milk and heavy cream, whisking constantly until your forearm aches to prevent lumps, then bring to a gentle simmer and cook for 3 to 4 minutes until the sauce thickens enough to coat the back of a spoon.
- Remove the skillet from the heat and stir in the Diamond Crystal kosher salt, black pepper, nutmeg, lemon juice, lemon zest, ricotta cheese, half of the parmesan, and half of the chopped herbs.
- Spread a thin layer of the white sauce on the bottom of the prepared baking dish, then arrange 3 lasagna noodles on top.
- Scatter half of the par-cooked shrimp over the noodles, drizzle with a third of the remaining white sauce, and sprinkle with a third of the mozzarella cheese.
- Repeat the layers: 3 noodles, the remaining shrimp, another third of the sauce, and another third of the mozzarella.
- Place the final 3 noodles on top, spread the remaining white sauce evenly over them, and top with the remaining mozzarella and parmesan cheese.
- Cover the dish loosely with foil (ensuring it doesn't touch the cheese) and bake for 25 minutes, then remove the foil and bake for an additional 10 minutes until the cheese is bubbly and golden brown. Let it rest for 15 minutes before slicing.
Notes
- I highly recommend using Diamond Crystal kosher salt for this recipe; if you only have standard table salt, cut the measurement in half (use 3/4 teaspoon instead of 1.5 teaspoons) to avoid over-salting the delicate seafood.
- Whisking ricotta directly into the warm BĂ©chamel sauce stabilizes the emulsion, preventing the cheese from curdling or separating into a grainy texture during the high-heat bake.
- Do not fully cook the shrimp in the skillet! They will bake for another 35 minutes in the oven, so pulling them out when they are barely pink prevents them from turning into rubbery, dry nuggets.
- Keep in mind that seafood lasagna absorbs liquid as it sits; after a day in the fridge, the noodles will drink up the sauce, making the leftovers slightly firmer but incredibly flavorful.
- If you are using oven-ready (no-boil) noodles, make sure they are completely submerged in the sauce during assembly, or the edges will remain crunchy and dry.
Serving Suggestions
To balance the rich, buttery layers of this seafood masterpiece, you want side dishes that offer brightness, acidity, and a bit of crunch.
- A crisp, citrus-forward green salad like our Avocado Citrus Salad to cut through the heavy cream.
- Warm, crusty artisan bread rubbed with raw garlic and dipped in olive oil.
- Lightly charred or roasted green vegetables, such as Garlic Parmesan Broccoli.
- A chilled glass of high-acid white wine like Sauvignon Blanc or Pinot Grigio.
Storage and Reheating
Handle leftovers with care.
Store any remaining lasagna in an airtight container in the refrigerator for up to two days.
Because shrimp can dry out rapidly, avoid the microwave if you can; instead, place a slice in an oven-safe dish, splash a tablespoon of milk over it, cover tightly with foil, and warm at 325°F (160°C) for 15 minutes.
I do not recommend freezing this dish, as the dairy-heavy white sauce tends to separate and turn grainy upon thawing.
Ingredient Substitutes
If you need to swap ingredients based on what is in your pantry, here are the most reliable conversions:
- Shrimp: Swap with bay scallops, crab meat, or even shredded chicken if you want to pivot to a Creamy Chicken & Mushroom Lasagna with White Sauce.
- Heavy Cream: You can use half-and-half, but the sauce will be slightly thinner; add an extra tablespoon of flour to the roux to compensate.
- Fresh Herbs: If you don't have fresh dill or parsley, use half the amount of dried herbs, though fresh is highly preferred for seafood.
- Mozzarella: Provolone or Fontina make excellent, melty alternatives that still provide that gorgeous cheese pull.
This creamy shrimp lasagna is the ultimate labor of love that actually delivers on its promise of decadent, restaurant-quality comfort. Pour yourself a glass of wine, take your time whisking that sauce, and enjoy the process of building something truly spectacular.
