Garlic Butter Shrimp Scampi Lasagna

Indulge in the ultimate comfort food fusion with this Garlic Butter Shrimp Scampi Lasagna. Plump, garlic-seared shrimp are layered between tender pasta sheets, a velvety white wine cream sauce, and a mountain of melted mozzarella and Parmesan cheese for a decadent seafood dinner everyone will love.

Why This Recipe Works:

• Par-cooking the shrimp prevents overcooking, keeping them plump and juicy during the final bake.
• A flour-thickened garlic butter roux stabilizes the cream sauce, preventing it from breaking or turning greasy under high heat.
• Freshly grated low-moisture mozzarella and Parmesan create a tight protein matrix that melts beautifully without releasing excess water.

I still remember the exact Tuesday evening my kitchen smelled like a seaside trattoria and a cheese factory had a beautiful, chaotic collision. I was trying to impress my partner with a seafood pasta. Instead, I ended up overcooking the shrimp into rubbery little erasers while the cream sauce broke into a greasy puddle on the plate.

It was a disaster.

The problem with combining delicate seafood like shrimp scampi with a heavy, baked pasta format like lasagna is a matter of thermal mass and protein structure. If you bake raw shrimp inside a heavy stack of pasta sheets for forty minutes, those proteins will tightly coil, squeeze out all their moisture, and turn completely chalky.

Worse, standard store-bought ricotta often releases excess water as it heats, turning your beautiful layers into a soggy, swimming mess.

To fix this, we par-cook our shrimp in a screaming hot skillet with garlic butter for just sixty seconds to build flavor through the Maillard reaction, then let them finish gently in the oven's residual heat. We also ditch the watery ricotta entirely in favor of a velvety, starch-stabilized garlic cream sauce—similar to the base of my Garlic Butter Shrimp Alfredo—which locks in moisture and prevents the dreaded sauce separation.

Trust me on this one, it makes all the difference.

Ingredients

• 12 lasagna noodles (oven-ready or boiled)
• 1.5 lbs large shrimp, peeled, deveined, and chopped
• 6 tablespoons unsalted butter, divided
• 6 cloves garlic, minced
• 1/4 cup all-purpose flour
• 3 cups whole milk
• 1 cup heavy cream
• 1/2 cup dry white wine (like Pinot Grigio)
• 1 tablespoon fresh lemon juice
• 1.5 teaspoons Diamond Crystal kosher salt
• 1/2 teaspoon freshly cracked black pepper
• 1/4 teaspoon red pepper flakes
• 2.5 cups low-moisture mozzarella cheese, shredded
• 1 cup Parmesan cheese, freshly grated
• 1/4 cup fresh Italian parsley, finely chopped

Directions

1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with butter.
2. Melt 2 tablespoons of butter in a large skillet over medium-high heat. Add the chopped shrimp and half of the minced garlic, searing for just 1 minute until barely pink, then immediately transfer them to a bowl to prevent overcooking.
3. In the same skillet, melt the remaining 4 tablespoons of butter over medium heat. Whisk in the flour to form a roux, cooking for 1 to 2 minutes until fragrant but not browned.
4. Slowly pour in the white wine to deglaze the pan, scraping up any browned bits, then gradually whisk in the milk and heavy cream until completely smooth.
5. Bring the sauce to a gentle simmer, stirring constantly, until it thickens enough to coat the back of a spoon. Stir in the remaining garlic, lemon juice, kosher salt, black pepper, and red pepper flakes, then remove from heat.
6. Spread a thin layer of the garlic cream sauce over the bottom of the prepared baking dish.
7. Place 3 to 4 lasagna noodles over the sauce, followed by a layer of the par-cooked shrimp, a generous drizzle of cream sauce, and a handful of mozzarella and Parmesan cheeses.
8. Repeat the layers twice more (noodles, shrimp, sauce, cheeses), ending with a final layer of noodles topped with the remaining cream sauce and a heavy blanket of mozzarella and Parmesan.
9. Cover the dish loosely with aluminum foil (make sure it doesn't touch the cheese!) and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown on top.
10. Let the lasagna rest for 15 minutes before slicing to allow the layers to set, then garnish with fresh parsley and serve.

Notes

• Salt Conversion: We use Diamond Crystal kosher salt. If you are using standard fine table salt, cut the measurement in half (use 3/4 teaspoon) to avoid over-salting your delicate seafood.
• Science of the Roux: We use a flour-based roux to stabilize the cream sauce. This prevents the fat in the heavy cream from separating from the liquid when exposed to the high heat of the oven, ensuring a velvety texture rather than a broken, oily mess.
• Workflow Warning: When sautéing the garlic in the butter, keep your eyes glued to the pan. Garlic burns in a flash, and burnt garlic will impart a bitter, metallic taste to your entire scampi sauce that no amount of cheese can save.
• Storage Behavior: Keep in mind that seafood lasagna behaves differently in the fridge than beef lasagna. The shrimp will continue to absorb moisture from the sauce overnight, making the leftovers slightly firmer but incredibly flavorful the next day.

Serving Suggestions

Complete your decadent seafood dinner by pairing this rich, cheesy lasagna with light, vibrant sides that cut through the buttery cream sauce.

• A crisp, green salad tossed in a zesty lemon vinaigrette.
• Warm, crusty Italian bread or a batch of my Italian Garlic Bread Sloppy Joes (minus the meat) to scoop up every drop of garlic butter.
• Quick roasted asparagus spears drizzled with fresh lemon juice.
• A chilled glass of dry Pinot Grigio or Sauvignon Blanc to complement the wine in the scampi sauce.
• Steamed broccoli florets tossed with a touch of sea salt.

Storage and Reheating

Leftover seafood lasagna is a beautiful thing, but it requires a little extra care to keep the shrimp from turning into rubber.

Store any leftovers in an airtight container in the refrigerator for up to two days. Because shrimp is highly perishable and delicate, I don't recommend pushing it past the 48-hour mark if you want to maintain the best texture and flavor.

When it comes to reheating, step away from the microwave. The intense, uneven electromagnetic waves will instantly overcook the shrimp while turning the outer edges of the pasta dry and leathery. Instead, place a slice in a small baking dish, splash a tablespoon of milk or water over the top to restore moisture, cover it tightly with foil, and warm it in a 325°F (160°C) oven for about 15 to 20 minutes until heated through.

This gentle reheating method preserves the delicate protein matrix of both the cheese and the seafood, keeping everything as luscious as the night you baked it.

Ingredient Substitutes

If you need to make a few swaps based on what's in your pantry, here are my tested and approved substitutions.

1. Shrimp: You can easily swap the shrimp for bay scallops, crab meat, or a mix of seafood. If you love scallops, check out my Garlic Butter Scallop Bake for inspiration on how to handle delicate shellfish.
2. White Wine: If you prefer to cook without alcohol, replace the dry white wine with an equal amount of low-sodium chicken broth or vegetable broth mixed with an extra squeeze of fresh lemon juice.
3. Lasagna Noodles: Standard boil-first lasagna noodles work beautifully, but high-quality oven-ready (no-boil) sheets are a fantastic time-saver—just ensure they are completely submerged in the sauce so they hydrate properly.
4. Heavy Cream: For a slightly lighter sauce, you can use half-and-half, but you may need to simmer the sauce a few minutes longer to achieve the desired thickness.

There is something incredibly comforting about a bubbling, golden-brown tray of lasagna, and adding the bright, garlicky punch of shrimp scampi makes it feel like an absolute celebration. Pour yourself a glass of wine, take your time whisking that beautiful cream sauce, and enjoy every single bite of this cozy masterpiece!
