Cheesy Broccoli Casserole

You know, it’s the holidays and I feel like maybe my kids could take it easy on me? Spread some holiday cheer, quit annoying each other for sport, and maaaaaaaybe stop begging me to play the horror video game Five Nights at Freddy’s. Have you guys heard of that game?

I mean, I like scary movies. If my husband is home, of course. I don’t watch them all alone like a mad woman or anything.

But, this video game that they beg me to play all the time is terrifying. They just pooled together their money to buy Five Nights at Freddy’s 2 and it’s even worse than the first.

I played a few minutes ago and now my heart is pounding and I’m all hot and sweaty. I’m in flight mode and setting here trying to type up this blog post is difficult. Creepy things are coming for me, I’m sure of it.

Basically, I’d like to ask for a refund on my children. They’re defective. Instead of singing me Christmas carols and baking me cookies, they’re plotting my murder with video games. Someone send help.

In the meantime, I’ll just be over here comforting myself with a big dish of vegetables. <—Yeah, I just said that.

I lightly steamed broccoli and cauliflower and then tossed it in a dish with some heavy cream and Kerrygold Dubliner cheese. You guys. I can’t even handle the cheesy perfection of this broccoli recipe. I love broccoli. Did you know that the first time I ever tasted it I was an adult? I was like, an adult adult. I was a mother the first time I tasted broccoli.

I’m making up for lost time now, because it’s my favorite veggie and it’s one that even my kids will eat. I usually just serve it steamed with a sprinkle of salt, but every now and then you’ve got to go all out.

The cream and cheese just add this sweet nuttiness that is only enhanced by the crispy parts of the broccoli that get roasted in the oven. I’m a sucker for roasted broccoli. I’ve been on a low carb kick lately, and this is one of my staples.

We also love this easy squash casserole and these oven roasted potatoes!
