Ingredients

All ingredients needed to make Keto Salisbury Steak with Mushroom Sauce.

Beef Bouillon Base – I like to use an organic, high quality bouillon base, one without a ton of added sugars. If you can’t find any, it can either be skipped or you could use a broken up beef bouillon cube.

Xanthan gum – If the mushroom sauce does not get thick enough on its own, xanthan gum can be sprinkled in to thicken it up.

How to make Keto Salisbury Steak

It’s a good idea to prep the veggies ahead of time. Slice the mushrooms, onion and garlic for the mushroom sauce and set them aside for later.

A bowl of sliced mushrooms and diced onion.

Heat a skillet on medium heat with the avocado oil. Mince the onion for the steaks and add it to a medium sized bowl with the dijon, worcestershire, salt, pepper, bouillon base and egg.

Mix well, ensuring the bouillon base is fully mixed in with the rest. Knead the ground beef into the wet until fully combined, then do the same with the almond flour.

Separate the beef into five equal portions and shape each into a patty.

5 beef patties.

Add the patties to the hot oil and sear, about 1-2 minutes on each side, then remove and set aside.

Now onto the mushroom sauce! Add the butter into the hot skillet along with the sliced mushrooms, diced onion, minced garlic, salt and pepper. Turn the heat up a little to medium high and continue to cook, stirring often, until the onion and mushrooms have turned golden brown.

Reduce the heat to low and add the beef broth and warmed heavy whipping cream. Whisk to fully combine and then place the low carb salisbury steaks right into the sauce. Allow the sauce to simmer for 5-10 minutes, until the internal temperature of the steaks has reached 165°.

Remove the steak, whisk in room temperature sour cream until fully combined, and if the sauce is not as thick as you like, sprinkle in the xanthan gum and whisk to combine.

Serve the keto salisbury steak on top of mashed cauliflower and top with extra mushroom sauce.

Instructions

Equipment Needed

Notes

  1. I like to use an organic, high quality bouillon base, one without a ton of added sugars. If you can’t find any, it can either be skipped or you could use a broken up beef bouillon cube.
  2. If the mushroom sauce does not get thick enough on its own, xanthan gum can be sprinkled in to thicken it up.
  3. Be sure to warm the cream before adding to the hot mushrooms. If it is cold, right from the fridge, it could curdle once it hits the hot skillet.
  4. Same goes for the sour cream. Leave it at room temperature while you cook the rest of the dish to warm it slowly from the fridge so that it does not curdle. If it is still cold when you need to add it, warm the sour cream slowly by adding a little of the hot mushroom sauce right into the sour cream. Give it a stir, add a bit more mushroom sauce, and repeat until the sour cream is warm.
  5. Depending on how hot your skillet was when the beef broth was added, your sauce may or may not be thick enough. This is why it is a good idea to have some xanthan gum. It will thicken that saucy goodness last minute if need be!
