I have a confession, I am 100% obsessed with cauliflower. You shouldn’t be too surprised since I have been posting a lot of cauliflower recipes lately…Cauliflower Bolognese, Cauliflower Lentil Sloppy Joes, and Roasted Cauliflower Orzo Salad. I was going to take a break from cauliflower, but it was on sale so I was forced to make another recipe:) I made Roasted Mustard Cauliflower and I am so glad I didn’t quit cauliflower because this easy recipe is AMAZING!

I wasn’t going to share this recipe on the blog for awhile because I thought you were probably all sick of my cauliflower obsession, but I shared a teaser on Instagram stories and I received A TON of messages from people begging for the recipe. So I guess you guys are obsessed with cauliflower too. YAY! We should start a cauliflower club. All of the cool kids will want to join us. We can wear cauliflower t-shirts and maybe even make cauliflower hats. Ok, maybe not so cool. Forget that whole club idea:)

Toss the cauliflower in mustardy goodness sauce and roast until crispy and caramelized on the edges. The extra crispy pieces are my favorite. I have to fight my boys for those. Yes, my boys ate this cauliflower and they loved it too! Roasting the cauliflower brings out the BEST flavor and the mustard sauce makes it even better.

This Roasted Mustard Cauliflower is an easy side dish and goes great with any meal. I could eat it every single day. Cauliflower club for life! Oh yeah, we weren’t going to do the whole club thing. Maybe it will have to be a secret club. I won’t tell if you won’t tell:)

    I’m totally obsessed with cauliflower too and yesterday while I was having dinner (of course with roasted cauliflower, because roasting brings out the BEST flavours), I was already thinking about the next cauliflower recipe I would make, and cauliflower+mustard seemed like a strangely good idea.
    So I googled it and BOOM your post comes up haha Will try it soon!
