If roasted garlic brussels sprouts did not change your mind about brussels sprouts, then hopefully this roasted brussels sprouts gratin with garlic crumble and crispy onion topping will.
Brussels sprouts are legit one of my favorite vegetables of all time. We have roasted brussels sprouts as least once a week and it’s always on my shopping list. I feel like those that despise them are just scarred from having a bad experience (re: boiled). You’ve gotta give this one a shot. The topping itself is WORTH IT.
Will you just LOOK at that gorgeous topping? Breaking into it was a little heartbreaking because it was like shattering the sugar top of creme brulee — but it also meant one step closer to having this delicious gratin on my plate.
I had extra garlic parmesan paste from my extra garlicky and cheesy bread so I mixed that with panko breadcrumbs to make the topping for this brussels sprouts gratin. But I didn’t stop there. I then used gourmet (as TJ’s would call it) fried onions and elevated the dish even more.
GAH YOU GUYS! You just seriously have to make this. Even if it’s not for Thanksgiving; what about for like a party or potluck? Or what if you just want pure comfort food in the form of brussels sprouts and garlicky oniony goodness? Because that’s my favorite kind of party. Well, sort of. Add some form of bubbly and friends…I’m all over that sign up list!
I wasn’t expecting this dish to be that awesome but since it is, I think this is THE dish I am bringing to Thanksgiving dinner this year! To be honest, this doesn’t have to be a Thanksgiving side dish. This can be a side dish year-round because WHY NOT?! I know Thanksgiving is pretty much all about side dishes but why not make side dishes a year-round thing?
I’m tempted to throw a side dish only party in July.
