Make this beef and mushroom recipe for comfort food that makes you feel good too

I walk a tricky line on Sunday afternoons and evenings between wanting all of the cozy comfort foods AND wanting to feel my best on a Monday morning. Luckily this beef and mushroom recipe with keto cauliflower mash dish brings me the best of both worlds.

It’s hard for me to know when my food is actually delicious and when I am just being biased, but I tasted this beef and mushroom dish and immediately said, “WOW this is good!” Thankfully my taste tester agreed and I hope that you all will too!

What is cauliflower mash?

Cauliflower mash is an alternative to mashed potatoes that is made by steaming cauliflower and blending with salt, milk, and butter. Cauliflower mash is keto friendly because it is much lower in carbohydrates than traditional mashed potatoes.

Replace your regular mashed potatoes with keto cauliflower mash

You might think that the beef and beef broth are the star of the show in this beef and mushrooms with cauliflower mash dish, but don’t sleep on the cauliflower mash! Ever since doing the Whole30 in January, my girlfriend and I have been converted from mashed potatoes to mashed cauliflower.

Its easier to make, so creamy and doesn’t leave me feeling Like I have a bowling ball in my stomach after I eat. When we are not following a Whole30 in this house we make it with salt, butter and heavy cream.

If we are following a Whole30 we use salt, ghee and almond milk! Both ways are delicious, but definitely something to note for my Whole30 friends.

How to make this beef and mushroom recipe

This beef and mushroom with cauliflower mash dish honestly looks harder to throw together than it actually is. For me this came together in less than 30 minutes which is the kind of thing I need when that evening hanger starts to set in!!

To make this comforting meal just take your flank steak and tenderize it. Then season on both sides and cube the meat. Toss the meat in tapioca flour and set aside.

Cut your cauliflower into florets and steam in its own pot. Slice the mushroom and onions. Heat some oil over medium and add the flank steak to the pan. Cook the flank steak for about 5 minutes.

Remove from the pan and add the mushrooms, onion and a splash of beef broth. Allow the veggies to soften, then add the remainder of the beef broth, the beef and a few sprigs of thyme.

Simmer for a few minutes to allow the flavors to combine and sauce to thicken. While this is simmering add cream and butter to steamed cauliflower and blend in the pot with an immersion blender. Serve beef warm with sauce over cauliflower mash!
