Beef slow cooks with mushrooms for a healthy meal the entire family will enjoy. Make this paleo, whole30, low-carb roast in your slow cooker or Instant Pot!
I’m hoping you like to pair beef with mushrooms as much as I do. Obviously you’ll need to like mushrooms in order to enjoy this recipe. There isn’t a substitute, the name of the recipe is beef with mushrooms.
Normally I don’t take the time to sear my roasts but for this recipe I actually did. I even went a step further and pre-cooked the onions and mushrooms and de-glazed the pan. Who am I ?? While I recommend these steps, they’re always optional. To me, slow cookers are truly meant to for quick and easy recipes so if you don’t have time for this step, don’t worry. Throw everything in the slow cooker; it will still come taste good.
Meat-so-tender-it-shreds-with-a-fork. That’s really what they should call slow cooker roasts. If your roast isn’t so tender it shreds easily then keep cooking it until it is. I used a round roast but other options include chuck roast, rump roast, you can even use brisket. The beauty of slow cooking is that even the toughest meats come out great.Print
