Dijon Mustard & Lemon Roasted Cauliflower

Sharing is caring!

A side dish of roasted cauliflower roasted in Djjon mustard and lemon butter sauce which is just delicious.

Just when I think I have done everything I can with a cauliflower, then another recipe pops up!   If you are a fan of mustard, then this dish is simply devine and the tang of the lemon is lovely.  I had to stop myself eating the whole dish once I tested a piece after it was cooked.   I almost fell upon it as if it were a chocolate mousse cake.   Absolutely gorgeous!    This sauce would also be good to pour over chicken, or perhaps a strong fish?   Or perhaps beef?   This is a wonderful side dish that could steal the show from the main course!

You could always make this dish a couple of hours ahead at then heat through when you are ready to serve.  I dare you to try and wait a couple of hours once you have tasted it though!  I am skipping off to purchase more cauliflower to make it again!

    I had some leftover pasta and I wanted a sauce with lemon since that was pretty much the only thing I had in the house. Seven minutes after finding this recipe I was eating. So simple… The Dijon mustard combined with lemon and butter is delicious. I am making the full recipe tonight with roasted cauliflower.

    I love whole grain dijon mustard – I’ve been addicted to it lately. Thank you so much for sharing this recipe! I have been trying to find more dishes that use dijon mustard and this one is definitely on the list.

      I agree with you about Dijon! It really makes this dish with the lemon and I hope you find it as addictive as I do!
