Roasted Cauliflower Vegan Mac + Cheese Recipe

GET THIS: It’s cheese-free.

The perfect fall side doesn’t exis————- hold the harvest!

I spoke too soon. When roasted, caramelized cauliflower and chickpea noodles are tossed in a creamy, non-dairy cheese sauce and topped with crispy salty prosciutto, you might find yourself tasting something dang near perfection.

Mac and cheese without the cheese?!? Yes and I swear you could fool the best of them. I’ve been making this vegan mac and cheese recipe based off of this dish for years because it tastes UNBELIEVABLY like the real deal and it’s made from veggies. Witchcraft? Possibly. But you’ll never look back!

Carrots, potatoes, onions, cashews and nutritional yeast are mixed together to make a creamy, insanely cheesy-tasting sauce. Nutritional yeast has a unique, cheesy flavor and can usually be found in the spices aisle of your grocery.

I love the flavor that roasting at high heat gives veggies — it concentrates their flavors, gives them a slight sweetness and the perfect tender/crispy texture!

You can easily make this dish vegetarian by leaving out the prosciutto as well.

Here’s how you’ll make Roasted Cauliflower Mac and Cheese:

  1. Roast cauliflower florets and prosciutto at 425 degrees for 20 minutes.
  2. Soak 1 cup of raw cashews in water.
  3. Meanwhile, bring a pot of water to boil + cook chickpea pasta.
  4. In a medium saucepan, boil onion, carrots and potato until soft.
  5. Blend together boiled veggies, cashews, nutritional yeast and seasonings to create sauce.
  6. Toss everything together and serve warm!

I hope this delicious vegan cheese sauce helps to open your mind to other veggie-based dairy substitutes! I love cheese as much as the next girl but eating it completely guilt free is an even deeper love 🙂

    I was following you before you competed on Guy’s Grocery Games but I’m way late to the game and just saw the episode lol. I was exited to try your cashew queso and decided to do the pasta version!

    So good! I’m a wimp and only did 1/2 tsp cayenne and still spicy but flavors and consistency were perfect!

    Love your recipes, keep ‘em coming! : )

    Thank you!
