Seafood Pasta Bake

There's something magical about opening the oven to find a seafood pasta bake bubbling away, golden cheese just starting to brown at the edges. I stumbled upon this dish years ago when a friend brought leftovers to a casual dinner, and I was immediately hooked by how the creamy tomato sauce clung to every piece of pasta and seafood. What struck me most was how effortless it felt to put together, yet it tasted like something you'd order at a proper Italian trattoria. The combination of tender shrimp, briny mussels, and the richness of cream made me realize baking pasta could be just as satisfying as any pasta dish I'd made before.

I remember making this for my partner on a particularly grey evening when neither of us felt like going out, and the aroma of the baking dish filled our small kitchen with this warm, comforting presence. By the time we sat down to eat, we'd already decided this was going into regular rotation. There's something about a baked pasta that transforms an ordinary Tuesday into something worth celebrating, especially when you plate it up with that creamy sauce still steaming.

Ingredients

• Penne or rigatoni (300 g): The tube shapes trap the sauce beautifully, so avoid long thin pastas that let everything slip right through.
• Mixed seafood (300 g): Thaw frozen seafood properly and pat it dry before adding, or excess moisture will make the dish watery and dilute all those beautiful flavors.
• Olive oil (2 tbsp): Use a decent quality oil you'd actually taste on bread, not the cheapest bottle.
• Onion and garlic: The aromatic foundation that makes everything taste intentional and layered.
• Canned chopped tomatoes (400 g): Quality matters here since this is your sauce's backbone, so pick a brand you trust.
• Heavy cream (150 ml): This is what transforms a simple tomato sauce into something luxurious and coating.
• Tomato paste (2 tbsp): A small amount deepens the tomato flavor without making things too acidic.
• Dried oregano (1 tsp) and chili flakes (1/2 tsp optional): The oregano whispers Italian seasoning throughout, while chili flakes add a subtle warmth if you like that heat.
• Salt, pepper, mozzarella, and Parmesan: Season boldly and don't skimp on the cheese topping, which becomes wonderfully golden and slightly crispy.
• Fresh parsley: A bright finish that cuts through the richness and looks intentional.

Instructions

Heat your oven and prepare:

Set your oven to 200°C (400°F) and grease a large baking dish so nothing sticks when you pour everything in later. This small step saves frustration and keeps your dish looking beautiful when you serve it.

Cook the pasta just shy of done:

Boil your pasta in well-salted water but stop two minutes before the package says, since it'll continue cooking in the oven. Drain it, set it aside, and don't rinse it—that starchy surface helps the sauce cling.

Build your sauce foundation:

Warm olive oil in a large skillet over medium heat and let the chopped onion soften for about three minutes, then add minced garlic and cook just until fragrant. You want to smell the garlic, not taste raw harshness in the final dish.

Deepen the tomato flavor:

Stir in your canned tomatoes, tomato paste, oregano, chili flakes if using, salt, and pepper, then let everything simmer gently for ten minutes. This time allows the flavors to meld and the sauce to lose its raw edge.

Add the cream and taste:

Pour in your heavy cream and simmer for another two minutes to marry the flavors, then taste and adjust seasoning because this is your last chance to balance everything before the seafood goes in.

Introduce the seafood gently:

Fold in your mixed seafood carefully and let it cook for just two to three minutes until it turns opaque—overcooked seafood becomes rubbery and ruins everything you've built. Trust that brief window.

Combine and transfer:

Toss the cooked pasta with the sauce and seafood until every strand is coated, then pour it all into your prepared baking dish. This is when it starts looking like the finished dish you imagined.

Top and bake:

Scatter mozzarella and Parmesan evenly across the top, then slide it into the oven for eighteen to twenty minutes until it's bubbling at the edges and golden on top. You'll know it's ready when the cheese smells toasted and the sauce peeks out around the edges.

Rest and finish:

Let it sit for five minutes after coming out of the oven so everything sets slightly, then garnish with fresh parsley for color and a bright flavor note.

One afternoon, my neighbor smelled this baking and appeared at my door with hopeful eyes, and I ended up making an extra portion on the spot because that's what happened when something smells this good. We shared it on my kitchen steps, and she told me it reminded her of a little restaurant near her childhood home, which felt like the highest compliment I could receive. Food has this way of connecting us across time and place, and this dish seems to do that effortlessly.

Why Seafood Pasta Bake Works as Comfort Food

There's a quiet confidence in baked pasta that stovetop versions don't quite capture—the gentle, even heat transforms everything into something cohesive and deeply satisfying. The cheese on top gets just crispy enough to add texture, while the creamy sauce below stays luxurious and coating. It's the kind of dish that feels abundant and indulgent without demanding technical skill or constant attention, which is exactly what comfort food should be.

Building Layers of Flavor

The secret to this dish singing is taking time with your sauce foundation—those few minutes of sautéing onion and garlic aren't wasted moments, they're where you build the flavor architecture that carries everything else. Adding tomato paste concentrates the tomato notes without making things acidic, and letting it simmer before the cream goes in allows all those flavors to knit together. By the time seafood and pasta join the sauce, you've created something with real depth that doesn't taste thrown together.

Making It Your Own

This recipe welcomes adaptation beautifully because seafood flavor is forgiving and versatile. You might skip the chili flakes entirely if heat isn't your thing, or add a splash of white wine to the sauce if you want brightness and complexity. Some nights I use crème fraîche instead of heavy cream for something slightly lighter, and other times I'll add a pinch of saffron if I'm feeling a little fancy and have it on hand.

• A squeeze of fresh lemon juice over the top right before serving brightens everything without overwhelming the seafood.
• If you have fresh basil available, use it instead of parsley for a different but equally lovely finish.
• Leftover portions actually improve slightly the next day as flavors continue melding, making this an excellent dish for meal planning.
