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.
