Have you tried to bake a whole cauliflower head yet?

Whole, not chopped up in pieces!

I had no idea how good a whole oven roasted cauliflower could be. I have seen them at restaurants, and skipped right over them when they were on the menu.

I feel pretty silly now because OMG this roasted cauliflower recipe is not only tasty, but roasted whole cauliflowers are so easy to make. They can even be a part of a sheet pan dinner! Toss on a pan and bake with your other dinner items! Add my easy creamy alfredo sauce recipe, and you have a delicious easy meal!

Mr. Fearless Dining reports that this baked whole cauliflower that we roasted and topped with my easy four ingredient homemade alfredo sauce is restaurant quality…better than anything he has tried. (And yes, Mr. Fearless Dining is the one who ALWAYS orders the roasted whole cauliflower off the menu!)

Just in case you thought I was kidding about the one pan dinner idea, this is how I cooked this gem. Side by side with a roast wrapped in bacon! If you love the one-pan meal idea, this easy Blackberry Tarragon Chicken Dinner is another dinner recipe to try.
