Ingredients You’ll Need

Every ingredient here plays a starring role in creating this ultra-creamy, seafood-packed comfort food. Simple, power-packed staples blend with top-notch seafood, offering both sophistication and absolute indulgence in every forkful.

• Lobster meat (8 oz): Sweet, succulent, and the “wow” factor in every shell.
• Lump crab meat (8 oz): Delicate yet flavorful, it pairs perfectly with the lobster for a satisfying seafood medley.
• Garlic cloves, minced (3): Brings aromatic depth that lifts the entire filling.
• All-purpose flour (1 tablespoon): Helps thicken the creamy sauce to luxurious consistency.
• Salt and pepper, to taste: Essential for seasoning and bringing all the flavors together—it’s the backbone of good cooking!
• Shredded mozzarella cheese (1 cup, divided): Melty, stretchy, and kid-approved; use half for the filling and half for the sauce.
• Butter (1 ½ tablespoons, divided): Adds richness to both the seafood and the sauce.
• Cream cheese (8 oz): The secret to that extra-creamy filling—smooth, tangy, and irresistible.
• Heavy whipping cream (½ cup): Ensures your cheese sauce is silky and indulgent.
• Parmesan Reggiano cheese, grated (¾ cup): Salty, nutty, and wonderfully melts into the sauce for a savory finish.
• Jumbo pasta shells (about 20 shells): Sturdy “boats” for your gorgeous seafood mixture.
• Aluminum foil: Keeps moisture in during baking so the shells come out perfectly tender.

How to Make Creamy Seafood Stuffed Shells

Step 1: Prepare the Seafood

Start by heating ½ tablespoon of butter in a large skillet over medium heat. Toss in the garlic and sauté until fragrant—about one minute is all it takes to make your kitchen smell incredible. Next, add your lobster and crab, cooking just until they’re warmed through and succulent (2-3 minutes). Don’t overcook—you want your seafood to stay tender and juicy. Set it aside, and get ready to mix up pure magic in the next step.

Step 2: Make the Filling

Grab a large mixing bowl and gently combine your cooked seafood, softened cream cheese, ½ cup of shredded mozzarella, plus a pinch of salt and pepper. Mix everything until it’s luxuriously creamy and the seafood is well distributed—this will be the star of your dish. Every scoop should feel rich and indulgent, just waiting to be tucked into a pasta shell.

Step 3: Cook and Cool the Pasta Shells

It’s time for the iconic jumbo pasta shells! Cook them according to your package instructions so they’re al dente—firm yet tender. Once they’re done, drain them and let them cool slightly. This makes filling them a breeze (and keeps your fingers safe from the heat). Your patience here will pay off in the end result!

Step 4: Prepare the Sauce

Let’s build that luscious cheese sauce. In the same skillet, melt your remaining butter over medium heat. Sprinkle in the flour and give it a minute, whisking constantly till it forms a pale, fragrant roux. Slowly pour in the heavy cream, whisking all the while so it stays smooth. Stir in the grated Parmesan and remaining mozzarella, then keep stirring until the sauce turns silky, glossy, and irresistible. This sauce is what brings everything together.

Step 5: Assemble the Dish (Don’t Forget to Preheat the oven to 375°F (190°C)!)

Now, preheat the oven to 375°F (190°C) before you start assembling—this step is key for a bubbly, beautifully browned finish. In a baking dish, spread a thin layer of that dreamy cheese sauce on the bottom. Fill each shell with generous spoonfuls of your seafood filling and nestle them snugly in the dish. Pour the rest of the sauce evenly over the top so every shell is coated in creamy goodness.

Step 6: Bake the Shells

Cover your baking dish tightly with aluminum foil, then slide it into the oven (remember, preheat the oven to 375°F (190°C)!). Bake for 20 minutes to keep everything juicy, then remove the foil and bake for another 10 minutes. This last stretch gives you a bubbling, golden crown that you’ll want to dig right into.

Step 7: Serve and Enjoy!

Once out of the oven, let your stuffed shells cool for a few minutes. This helps them set up so they stay picture-perfect on your plate. Top with extra Parmesan or a sprinkle of fresh herbs, then serve while still warm and marvel at your creation!

How to Serve Creamy Seafood Stuffed Shells

Garnishes

For a final flourish, I love to shower the shells with extra grated Parmesan and a scatter of chopped fresh parsley or basil. A squeeze of lemon right before serving adds a bright, fresh hit that cuts through the richness. Cracked black pepper or a pinch of red pepper flakes brings a gentle kick if you fancy a little spice.

Side Dishes

Pair these indulgent shells with something light and vibrant. A crispy garden salad with a lemony vinaigrette balances out the richness, or go classic and serve with steamed asparagus or green beans. For bread lovers, a loaf of crusty Italian bread is perfect to soak up every drop of that gorgeous sauce.

Creative Ways to Present

If you’re entertaining, consider serving individual portions in small baking dishes or ramekins for a restaurant-worthy touch. You can also top each portion with a little extra cheese and broil for 2-3 minutes for a bubbly, golden finish. Plating on a bed of wilted spinach or arugula adds color and a peppery contrast.

Make Ahead and Storage

Storing Leftovers

Let leftovers cool completely before transferring to an airtight container. These shells will keep in the refrigerator for up to 2 days. The flavors deepen even more, so they’re just as delicious for lunch the next day!

Freezing

To freeze, simply assemble the shells (but don’t bake). Cover tightly with aluminum foil and freeze. When you’re ready to enjoy them, thaw overnight in the refrigerator, then preheat the oven to 375°F (190°C) and bake as directed. This makes a fabulous make-ahead option for busy weeknights or special occasions.

Reheating

Reheat individual portions in the microwave, or for best results, cover the baking dish with foil and warm in your preheated oven at 375°F (190°C) until heated through (about 15-20 minutes). Add a splash of cream or extra cheese sauce before reheating to refresh that creamy texture.

FAQs

Can I use frozen seafood instead of fresh?

Absolutely! Just make sure to thaw it thoroughly and gently press out excess moisture before using. This helps prevent a watery filling and keeps your shells creamy and luscious.

What type of pasta shells work best?

Jumbo pasta shells are ideal since they hold plenty of creamy filling and bake up perfectly. Avoid using smaller shells, as they won’t have enough room for your decadent mixture.

Could I swap out the seafood for something else?

Definitely! Chopped cooked shrimp or even cooked scallops make great substitutes if lobster or crab isn’t available. You could also try a mix for extra flavor and texture.

Is it possible to make these shells in advance?

Yes, you can assemble everything a day ahead, cover with foil, and refrigerate until you’re ready to bake. When it’s time to serve, preheat the oven to 375°F (190°C) and bake as directed, adding a few extra minutes if they’re cold from the fridge.

What if I don’t have heavy cream for the sauce?

You can substitute with half-and-half or even whole milk in a pinch, though your sauce will be a bit lighter. Adding a tablespoon or two of extra cream cheese helps maintain creaminess.
