Frequently Asked Questions
- → Can I prepare this dish ahead of time?
You can get everything ready beforehand. Just wait to combine and bake until serving. Storing cauliflower in cream for too long can make it watery.
- → How do I keep cauliflower from being too soggy?
Steam it lightly and pat dry before mixing it in. Cooking it al dente helps prevent extra moisture.
- → Are other cheeses okay to use?
Sure, swap gruyère for emmental or comté. Just pick a melty cheese and pair it with a firmer one like parmesan.
- → Can I use frozen seafood?
Yes, but thaw it completely and make sure to dry it thoroughly. Excess water from seafood can make the bake runny.
- → How do I reheat leftovers?
Use the oven at 180°C instead of a microwave to keep the creamy texture and crispy topping.
