Roast Cauliflower Mac and Cheese

Mac and cheese is sure-fire crowd pleaser. Over the last 7 years of blogging, I’ve shared have several of our favourite versions, this Roast cauliflower Mac and Cheese being one of the all time favourites. While the recipe is my own, the idea to use a sheet pan is one I found on Food 52. Amanda Hesser explains that a baking sheet is the only way to ensure everyone has their fair share of crunchy toppings.

Roasting the cauliflower adds a lovely nuttiness. Most of the ingredients for the recipe are kitchen basics like milk, bread, butter and cheese. The topping for my roasted cauliflower Mac and Cheese is a combination of salty Parmesan and walnuts, although a sharp cheddar or gruyere can also do the job. If you prefer a stringy cheese, mozzarella is the only cheese that can deliver the pull. Pasta doesn’t like hanging around so get everyone around the table before it comes out the oven.

    Much more crunch per bite, right? A complete win with my family every time.

  • Looks wonderful! Can you convert to ounces, tablespoon/teaspoon, and fahrenheit? Will a 9×13 inch glass pan work?

    I’m hoping to make this for my son’s 3rd birthday! Thank you!!

  • Hi there Minh-Hai. Sure. You can bake the pasta at 350 fahrenheit. If you have a slightly bigger dish, you’ll get more topping into each bite. If not, the 9 x 13 will be fine. 1 Tablespoon = 15ml and 1 teaspoon = 5ml. For the weight, 50g = 1.8 ounces and 60g = 2 ounces. Hope that helps.
