15 Easy Seafood Casseroles to Conquer the Sunday Scaries

Hey, seafood!

Let’s talk about Sunday Scaries for a minute: you know, that moment when you realize tomorrow is Monday. And not only is your next week full, but your meal prep game is nonexistent. Before you fall into the temptation of takeout, let us introduce you to your new weekend warrior: the anything-but-boring seafood casserole.

We’re talking 15 sophisticated wonders that will make your future self want to high-five your present self! Think of this collection of recipes as your own personal kitchen time machine. While you relax in your weekend sweats, you can assemble the masterpiece of next week’s meal, stash it in the fridge, and turn those Sunday dreads into delicious seafood dishes faster than your kid (or your partner) can say” What’s for dinner?”

Let’s be real: In the time it takes to scroll through delivery apps and argue over toppings, your make-ahead wonder could already be bubbling in the oven, filling your home with comforting aromas that will have your family gathering around the table, sooner you also call to eat.

The beauty of these dishes lies in their “whatever works” flexibility. Got some frozen peas stashed in the back of the freezer? Throw them in. That half-empty box of quinoa from your health kick last month? Perfect. Some cheese that needs a purpose in life? Welcome to the party. The only non-negotiable is seafood, which adds a slew of nutritional benefits like protein that really keeps you full, a bevy of beneficial vitamins, and omega-3s to aid heart health!

In keeping with our KISS (Keep it Simple, Seafoodies) mantra, consider this your permission to break the rules. These aren’t just 15 great fish casserole recipes — they’re starting points for your creativity in the kitchen. Because let’s face it, the best cuisine is the one that fits your life, not the other way around.

So grab that casserole dish, channel your inner chef, and show Monday who’s boss. Your future self will thank you, and who knows, you might start looking forward to the start of the week!
