What To Do
1. Steam or boil the cauliflower florets until tender (about 5-7 minutes); drain very well.
2. Make the sauce: In a large saucepan, simmer heavy cream and cream cheese until smooth.
3. Whisk in the Roasted Garlic Cheddar and dry mustard until the sauce is thick and glossy.
4. Combine: Fold the cauliflower into the cheese sauce until every floret is coated.
5. Bake (optional): Transfer to a dish and bake at 375°F for 10 minutes for a bubbly, golden top.
