Loaded with flavor from garlic, Dijon, and dill, this vegan mustard roasted cauliflower side dish is easy to make with only 5 ingredients. If you enjoy the taste of Dijon salad dressing, this is the recipe for you.
There's nothing like roasting vegetables to bring out their flavor. And while it's common to use olive oil and salt and pepper, you can add other ingredients, as well.
Inspired by my Mediterranean cauliflower salad, this mustard roasted cauliflower recipe stars tangy Dijon mustard. Along with garlic and fresh dill, it elevated the flavor of this cruciferous vegetable.

I didn’t have Dijon so I use 2 tablespoons of Stone ground and 1 tablespoon of regular mustard and I couldn’t fit the whole head of cauliflower in the dressing so it was about 2/3 of the head I would guess. I use the air fryer. It’s pretty good. I would’ve probably liked some more coating, but I would make this again. It was easy and simple and what else could you ask for?
Amy Katz says
Great! I hope you try it with extra coating next time. I bet you'll like it even more. 🙂
SG says
Easy and very tasty recipe with great instructions. I made it for Mother's Day. Thanks you!
Amy Katz says
I'm so happy you enjoyed it and found it easy to make!
Korina says
Hi would this work without the dill or with another herb? I've got a family of non dill likers (except me). Or would you suggest just a bit of dried dill added to the sauce instead to give it a little dill flavour without the very obvious dill garnish?
Amy Katz says
You can use a different fresh herb such as parsley. (Or you can leave the herbs off entirely and just add some fresh dill to your portion only.) But this dish is still delicious without the herbs. I hope you enjoy it, Korina!
Terry says
I thought I had enough cauliflower recipes, until I tried this one! The other recipes will be deleted. This is so good! Does the sauce work on broccoli? Thank you!
Amy Katz says
Thank you so much, Terry! Yes, broccoli will work great!
