Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese

Balsamic caramelized onions and flavorful mushrooms are a winning combo in this creamy, insanely cheesy mac ‘n’ cheese! Perfect weeknight comfort food.

Mmmmmkay, guys. I’d say it’s most definitely time for some hard-core comfort food.

Can balsamic caramelized onion mushroom mac ‘n’ cheese deliver? Ohhhhhh yes it can.

Can I eat that whole skillet solo? Bet.

So it turned fall here like overnight, guys. Not even kidding the amount of soups, casseroles, and cozy foods that are now being craved. Mac ‘n’ cheese is totally a year-round kinda comfort food deal but even MORE SO right now. I wanna eat this every day forever, the end.

We’re gonna start off nice and simple with a base of flavor GOLD like balsamic caramelized onions, sauteed mushrooms, and garlic hanging out in a rich, luscious cheese sauce.

It’s really, really good. A mess ‘o elbows thrown into the party only makes things wilder and way way better. As carbs tend to do. There’s also both sharp cheddar AND Parm cheese in this mac, guys.

The more cheese the merrier is what the Wisconsinite in me will always preach. ✌️✌️

You will unashamedly be eating this mac straight outta the pan, guys. It is the REAL DEAL cozy food.

Plates unnecessary. Just don’t even bother.
