Troubleshooting Cooking Whole Roast Cauliflower

If the whole roasted cauliflower is sliced immediately after cooking it may fall apart.

Cool whole baked cauliflower for at least 15 minutes before slicing or quartering it to avoid it falling apart when slicing.

The stem may be a little al dente compared to the rest of the cauliflower. Next time try boiling it for a couple minutes longer.

If the florets are too soft then try cooking for less time next go around.

Turn the oven down 25-50 degrees to 375F or 400F if the whole cauliflower browns or burns too fast.

If the whole cauliflower does not brown at all try turning the oven up 25-50 degrees to 450F or 475F.

Notes

Larger cauliflower heads need to be boiled for 9-10 minutes in 2" of water.
Smaller cauliflower heads need 7-8 minutes boiled in 1 ½" of water.
If the whole cauliflower is not browning then bring the temperature of your oven up to 450F.
If the cauliflower is browning to fast, drop the temperature of your oven to 375F or 400F.
Flip the sheet pan in the oven half way through if one side of your oven cooks faster than the other side.
