How to make the gratin

Cook the cauliflower
Steam the florets for 5-7 minutes until they're tender but still have some bite.
Get the seafood ready
Heat olive oil in a pan over medium heat. Cook the chopped garlic until fragrant, then add the shrimp and scallops. Season them and cook for 2-3 minutes until they turn pearly white.
Mix everything together
Combine the cauliflower, seafood, and cream in a large bowl so all ingredients get nicely coated.
Build your gratin
Pour the mixture into a buttered dish. Sprinkle Gruyere and Parmesan on top.
Bake it
Put it in a preheated oven at 200°C for 25-30 minutes until you get a beautiful golden crust.
Finish up
Take it out of the oven, sprinkle with chopped parsley and serve right away.

Frequently Asked Questions

→ Can I prep this ahead of time?

Sure, but keep the assembly and baking until later. Letting cauliflower sit in the sauce for too long could make it watery.

→ How do I keep the cauliflower from being soggy?

Steam it lightly and dry it thoroughly before adding it in. Cooking it until just tender helps prevent extra moisture.

→ Can I swap out the cheeses?

Of course! Go for emmental or comté instead of gruyère. You want one melty cheese plus a harder one like parmesan.

→ Are frozen seafood mixes okay?

They work fine if you defrost them fully and pat them dry. Excess moisture can make your bake too wet.

→ What's the best way to reheat leftovers?

Stick it in the oven at 180°C instead of using the microwave. The oven keeps it creamy and gives the top its crisp texture back.
