Ingredients You’ll Need:
Here’s my simple and wholesome ingredient list for creamy seafood gratin. Trust me, it’s streamlined because busy moms like us need nutrition without complexity!
- 1 lb mixed seafood (shrimp, scallops, crab meat, or firm white fish) – rich in protein and omega-3 fatty acids
- 2 cups milk (whole or 2%) – for a creamy base that’s calcium-rich
- 2 tbsp butter – adds flavor and smooth texture
- 2 tbsp all-purpose flour – helps thicken the seafood sauce gratin
- 1 cup shredded cheddar cheese – kid-friendly and adds great melt without overpowering
- 1/2 cup grated Parmesan cheese – boosts savory depth in this baked shellfish gratin
- 1/2 cup chopped onion – mild sweetness and fiber
- 2 cloves garlic, minced – antioxidant perks and flavor punch
- 1/2 cup panko breadcrumbs – gives a crunchy topping for your cheesy seafood bake
- Salt and pepper to taste
- Fresh parsley for garnish – optional but adds a fresh pop
No worries if you don’t have cheddar on hand – I sometimes swap in a mix of mozzarella and Gruyere for extra gooeyness and melt power. Or if you want a lighter creamy seafood gratin, using a milk alternative like oat milk works great, too!
You can find these ingredients at your regular grocery store. For budget-friendly swaps, canned seafood like crab or shrimp works well. Keeping these staples on hand means dinnertime nutrition wins even when life feels chaotic.
To save time, I often prep seafood by peeling and cleaning the shrimp ahead on the weekend, so I’m ready to assemble this creamy baked seafood dish faster during the week. My family also gets extra nutrition when I toss in chopped spinach or peas — stealthy veggies that melt right into the creamy sauce.
Let’s Make it Happen!
Ready to make this creamy seafood gratin come to life? Here’s my step-by-step, kitchen-tested method, perfect for busy moms juggling a million things.
- Preheat your oven to 375°F. This allows your baked shellfish gratin the perfect cozy heat to develop golden bubbly goodness.
- Prepare the seafood: If using raw shrimp or scallops, rinse and pat dry. If pre-cooked, just drain and set aside.
- In a saucepan, melt butter over medium heat. Add chopped onion and garlic, sauté for 3-4 minutes until soft and fragrant. This step unlocks that savory base for your creamy seafood gratin.
- Sprinkle flour over the butter and onions, stirring constantly for 1-2 minutes — this makes your thick, luscious seafood sauce gratin.
- Slowly whisk in the milk. Keep stirring until the sauce thickens like creamy pudding – this usually takes about 5 minutes. Patience here means a silky seafood casserole base.
- Stir in cheddar and Parmesan cheeses until melted. Your kitchen will smell like comfort and a little celebration.
- Add the seafood into the sauce, folding gently so everything is coated evenly.
- Pour into a greased baking dish. Sprinkle panko breadcrumbs and a little extra Parmesan on top for that irresistible crunchy topping.
- Bake uncovered for 20-25 minutes, until bubbly and golden brown. Don’t worry if the gratin looks a little runny before baking; it firms up as it cooks.
- Take a moment to breathe! While your creamy seafood gratin bakes, perfect time to prep tomorrow’s lunch or tidy the kitchen.
In my busy kitchen, this nutritious creamy seafood gratin usually takes about 45 minutes total. I’ve found that using a mix of seafood keeps flavors interesting and helps the kids try something new. The sauce’s creaminess hides the textures some picky eaters resist!
