Pot roast has to be one of the best comfort foods around and with a slow cooker, it’s so easy to make! This pot roast is crusted with a super tasty mixture of dried mushroom powder, dijon mustard, miso paste, parmesan cheese, garlic, thyme, Worcestershire sauce and pepper that infuses the beef with its magical flavours as it slowly roasts in the slow cooker! The beef is placed into the slow cooker on top of a bed of mushrooms, onions, carrots and potatoes which cook in beef broth making this a really easy one pot meal where everything is ready when you get home from work. The veggies are cooked at the bottom of the pot so that the drippings from the roasting beef along with some of the beefs seasoning comes down and infuses them with even more flavour! When the beef is roasted until fall apart tender you remove it from the pot to sliced, add some cornstarch to the liquid and cook in the slow cooker on high until it thickens and forms a tasty gravy to smother everything in! What an easy and tasty meal!

What do you do to dried mushrooms ground to a course? And what is miso paste and where do you get it? Thanks.
The ground dried mushrooms are mixed into a paste and rubbed onto the beef. Miso paste is a salty fermented bean paste that can be found in the international section at your grocery store (or the sushi section) or at an Asian grocery store. You could omit the miso paste and add extra salt to the rub mixture. Enjoy!

I’m going to make this in the oven using a dutch oven. Is 1/2 cup of the Beef Broth enough liquid to prevent burning? I’ll be cooking at 300 degrees for 3 hours.
2 cups of broth will do in the oven, with a lid on the dutch oven. Enjoy!
This new recipe sounds delicious..!! I can’t wait to try it, Kevin..🙂
Looks great but I don’t see the cornstarch/water mixture listed with the ingredients. How much of each. Thanks.
