Slow Cooker Mushroom Mac and Cheese

The mushrooms are the real star here. The butter melts, the mushroom drippings soak into that cheesy goodness and I’m sure you get the picture—it’s going to be good.

It wasn’t until last year that I caught on to the wonder and ease that is the crockpot. I know I'm way late to the game, but for years I had the misguided notion that crockpots were for home cooks who had given up. Crazy, I know. Who was I ever kidding that I could work part time, raise three kids, and crush dinners Monday-Friday all cooked over a stove and dirtying an embarrassing amount of dishes each night? Finally, in a mad attempt to get some sort of manageable grasp on our dinner routine I busted out a crockpot for the first time in my 8 years of homemaking. Mind blown! Endless recipe possibilities, and tons of nutrition and flavor packed in one easy dish that I don't have to stand stirring for an hour?...well, even better. For all these reasons and more I am thrilled to be partnering with Fred Meyer stores in celebrating #crocktober: an entire month devoted to delicious crockpot recipes that will add some serious ease and excitement to your dinner routine.

Generally, when thinking of crockpot recipes my mind jumps to stews, soups or roasts, so I wanted to mix it up a bit. And so, without further adieu allow me to introduce you to crockpot mushroom mac and cheese. Guys, it's so good!

When I was developing this recipe I couldn't help but think of my favorite Disney Pixar movie, Ratatouille. There’s a scene where the rat chef accidently toasts a mushroom by way of electric shock. He bites down into the toasty fungi and chases it with a bite of French cheese. It’s at that moment that fireworks start going off in his mind representing the satisfaction his tastebuds are experiencing. This mushroom mac and cheese? Yeah, it’s like that. Fireworks exploding, angels name it…as you bite into the perfectly paired flavors of mushrooms, sharp cheddar, parmesan, and gruyere cheese melted together over pasta.

In order to infuse the mac and cheese with the nutty, earthy flavor we all love so much about mushrooms we’ve flipped the caps, filled them with butter and placed them along the top of the dish in the last hour of cooking. The butter melts, the drippings soak into that cheesy goodness and I’m sure you get the’s going to be good.

    Could this be doubled in the same crock pot?

    If it will all fit, I don't see why it wouldn't!

  • K. Fischer

    Love, love mushrooms, so when you add it to Mac & cheese....I think I’m in love. 😍😋

    This recipe is easy to fall in love with!

  • Teresa

    This was the best mac and cheese I've ever had. I made a few changes. I just used the recipe as a base for any topping, so replaced the mushrooms with pork rinds mixed with bacon and bacon fat for a crispy element on top. I used oatmilk instead of milk, and a can of coconut milk instead of evaporated milk. Thank you so much for an amazing treat.

    Thank you, Teresa! Way to experiment with substitutions that work for you and happy you loved it!
