FAQs
Can I use frozen cauliflower for this recipe?
While fresh cauliflower works best for roasting, you can use frozen florets if dried thoroughly. Roast a bit longer to achieve a tender and browned texture.

Dijon mustard provides a smooth, tangy flavor, but you can substitute with whole grain or yellow mustard if preferred. Keep in mind this will slightly change the taste profile.
