Onion and Potato Mac and Cheese Bake

Delicious freshly cooked Macaroni and cheese with a metal spoon.
All right, we’ve tried a lot of macaroni and cheeses in our time – just about every variety, or so we thought…. The cauliflower-packed versions, the store-bought iterations, the Martha Stewart staples (https://bit.ly/2AgHW05), we love giving them each a shot (and have found ourselves totally hooked on many of them), but thought we’d kind of exhausted all possible options in terms of reinventing the classic dish. That was, until we realized we hadn’t really tried a recipe where veggies were totally integral to this dish. Unlike cauliflower, we weren’t trying to put vegetables in here, hoping no one would notice them, we wanted these veggies to shine!

Obviously, in order to sell this to the die-hard mac and cheese fans in our life, we had to make sure the cheesy sauce – i.e. the most important part of the whole thing – lived up to everyone’s standards. Similar to our other favorite versions, we made a roux-based sauce and then added ridiculous amounts of cheese. Yum, can’t go wrong with tons of cheese! And to that we added our perfectly sautéed veggies and cooked pasta. Sautéeing the vegetables first ensures you don’t get weirdly crunchy bites interspersed between your al dente noodles, plus, we season them up and brown them just a little, so you get a great, round depth of flavor that will have you hooked. Seriously, our kids didn’t even realize how many veggies we packed in here!

Delicious Macaroni and cheese
This dish is a little bit of work and you do end up using a couple dishes throughout the process, but please don’t let that stop you! (And definitely wrangle someone else into doing the dishes.) We can’t begin to explain how yummy this is, or impress upon you enough how glad you’ll be that you made this. Bonus: it freezes exceptionally well, so if you happen to make it and freeze it, people will be praising your name weeks down the line when they take their first bite!
