Guys, get ready.

I’m about to share some exciting news with you and I want you to be fully prepared. Hold on to your hats. Take a seat. Buckle up.

This is big.

My kids ate vegetables last night and they were happy about it.

I mean, maybe just maaaaaaaybe it has something to do with the ultra creamy cheese sauce that I poured over the top, but who can say for sure.

I am a total sucker for roasted vegetables and I bet most of you are too. So, rather than steam the cauliflower and broccoli in this gratin recipe, I popped it in the oven to roast. And THEN! (this is the part where it gets really good) I made this utterly heavenly cheese sauce with Roth Original Havarti Cheese.

Y’all.

This cauliflower au gratin is so good that even my picky kids asked for seconds.

I am a fan of creamy dreamy Havarti cheese. I normally just slice it up and serve with crackers, but it is divine when melted into a cheese sauce. Like, out of this world good and it pairs so well with the nutty flavors of roasted broccoli and cauliflower.

Basically, if my kids ate a vegetable recipe and didn’t complain, you are for sure going to like that recipe. Because my kids, man. They can sure complain about some vegetables, if you know what I’m saying.

Also, hello, silky smooth cheese sauce. I want to marry you and have your babies.

Roth uses traditional cheese making methods with milk from local Wisconsin farmers to create an ultra creamy Havarti. The original flavor is perfect for this cauliflower gratin, but be sure to snag a package of the jalapeno Havarti too. Because how could you not? I mean, imagine that on your cheese plate for Thanksgiving alongside some cranberry jelly. Cracker + jalapeno Havarti + cranberry jelly = life.

I’m so excited to dump this cheese sauce over some pasta next time. Think about how amazing mac and cheese would be with creamy Havarti in place of the dreaded block of orange cheese-like substance? Totally dreamy. Or maybe just grating it over my French dip sandwich for a delightful dinner experience. I just know I want more cheese in my life, okay?
