I used a combo of broccoli and cauliflower because it's what I had on hand. Really glad I did! Classic flavor combo and so easy to throw together on roasted vegetables makes this infinitely adaptable. Subbed some garlic oil for the butter, and I was tempted to do as directed and make it all on the sheet pan - but for the sake of cleanup - I roasted on aluminum foil and tossed the florets in a bowl where I'd already whisked the oil, vinegar, and mustard. Perfect!
This did not turn out well as written. The butter and vinegar go their separate ways on the hot baking sheet and are impossible to emulsify. The second time around I pre-melted the butter and whisked it together with the mustard and vinegar in a large storage bowl that has a lid. Then I added the roasted broccoli, put on the lid, and shook it gently for half a minute or so. Worked much better. I also preheated my sheet pan for a nice under-char on the broccoli. Tastes great.
I've made this a few times and find it comes out best if I pre-heat the cooking sheet in a 425° oven before adding the broccoli.
I like this with smaller bite-size pieces of broccoli. Added slices of garlic to the pan. Followed others' suggestions to mix melted butter, vinegar and mustard in a bowl and add the broccoli right after it is cooked. I did it at 425 since the pieces were smaller. It was good after 15 minutes - I'll try a shorter time next time as I like the broccoli to retain a little crunch.
Any new roasting instructions for this recipe if I only use frozen broccoli? E
Can i adapt to an air fryer?
@Alicia I don’t see why not. Air fry at 375° for about 9 minutes. I would then toss with the mustard mixture in a separate container.
