Why You’ll Love This Recipe
If we go to a restaurant and they serve Crispy Brussels Sprouts, I order them! Just ask my husband. So I’m sure he’s glad I’ve learned to make them at home.
Or maybe not…..since he doesn’t care for Brussels sprouts. He’s totally missing out, of course. But that’s okay–it just means more Brussels sprouts for me.
I admit, I hated Brussels sprouts as a kid. I mean, who didn’t? Now, along with things like pasta salad and potato salad (which I also hated as a kid), I love them. Like, a lot.
Even better when they’re served with something delicious for dipping. Maybe if I’d been offered this delicious Dijon mustard aioli as a child, I would have liked Brussels sprouts back then.
Who are we kidding? Probably not. But now I’d eat these crispy, crunchy veggies every day. Especially since this recipe is so incredibly easy to make.

The Brussels sprouts themselves are simply tossed with olive oil, salt and pepper. That’s it! The secret to getting them crispy is cranking up the oven to 450 degrees.
Fifteen to twenty minutes later, you’ve got delicious sprouts that are tender on the inside and crispy on the outside. Which gives you just enough time to whip up the aioli.
If you’re wondering what aioli is, it’s a garlic sauce usually made with eggs and olive oil. Kind of like mayonnaise–which is what I use in this recipe to make things quick and easy.
Of course, the Brussels sprouts aren’t quite as healthy dipped in a mayonnaise based sauce, but I say when you’re eating something so healthy, why not indulge a little.
If you’re in charge of the appetizer or side dish for Thanksgiving dinner, it doesn’t get any easier than these Crispy Brussels Sprouts with Mustard Aioli. If you’re not a fan of Brussels sprouts, this recipe may just win you over!

I made this tonight. I LOVE Brussels sprouts and this dipping sauce was a nice addition. I also realized that I had been cooking my brussel sprouts about 25 degrees too low. I did use garlic powder instead of the minced garlic as sometimes raw garlic upsets my stomach.

Thank you! So glad you liked it. And yes, I like the higher temperature because I love those crispy edges!
