Parmesan Roasted Cauliflower


Total Time:



We do a LOT of quick / fun / easy dinner recipes here on What’s Gaby Cooking but I also feel VERY strongly about a good side dish. This Parmesan Roasted Cauliflower is the perfect example!

There were many occasions back in my private chef days when people would be anti-veggies. I think that stems from not knowing how to cook them years ago and never growing to love them. Here’s the deal – if you cook them right, you’ll be hooked. Take my roasted potatoes for example – best potatoes ever. Brussels – obsessed. Adults love them, kids love them, everyone wins. Same goes for this Parmesan Roasted Cauliflower. It’s roasted until the outside areas are caramelized and flavored with tons of onion, thyme, garlic, oil, salt and pepper. Simple but perfect. It’s finished with a touch of Parmesan but you could easily leave that you if you’re vegan or non-dairy.

Make it!! You won’t be disappointed! Everything about it makes me happy – including peeling the individual cloves of garlic once they are roasted and slathering them on every piece of cauliflower. YES PLEASE!

ALSO – side note. If you make this on the regular like me, it’s pretty freaking awesome when you dip the leftovers in hummus. Just saying.

    If I want to bring this for Thanksgiving, what the best way to reheat it? Should I add the Parmesan or wait until the day of?

    • Gaby

      you can make it entirely ahead of time – and pop it into an oven for 15 minutes at 350 before serving to warm it back up

    I added 2 extra spices to cauliflower while baking and added extra Parmesan. It had a great flavor! This dish is good to take to a dinner and serve at room temperature. Was enjoyed by all!
