The Easy Process

Make-Ahead Advice
You can prepare the cauliflower and sauce a day in advance. Store them separately in the fridge to keep the texture best. Combine and bake just before you are ready to serve dinner.
Leftovers stay fresh in the fridge for up to four days. Reheat them in the oven at 350°F to keep the top crisp and golden. Avoid the microwave to prevent the sauce from becoming oily.
Tips for Best Results
- Pat the steamed cauliflower very dry to avoid a watery sauce.
- Don’t skip the nutmeg because it enhances the cheese flavor perfectly.
- Use a block of Gruyère and grate it yourself for better melting.
- Whisk the milk in slowly to ensure your sauce stays silky smooth.
- Prepare this as a festive side for your Christmas or Thanksgiving table.
- Add a pinch of cayenne pepper if you want a tiny kick.
Easy Swaps

- Add a handful of cooked bacon bits for a smoky winter twist.
- Swap half the cauliflower for broccoli to add more vibrant color.
Common Questions
Can I use frozen cauliflower?
