FAQ

Can I use frozen cauliflower instead of fresh?

Yes, but add it during the last 10 minutes of cooking since frozen cauliflower cooks faster and can become mushy if overcooked.

What if I don't have a Dutch oven?

Any large, heavy-bottomed pot or deep skillet will work. The key is having enough space for all ingredients and good heat distribution.

How long will this keep in the refrigerator?

Store covered in the refrigerator for up to 4 days. Reheat gently on the stovetop, adding a splash of water if needed to loosen.
