Low-Carb Slow Cooker Mushroom Lover’s Pot Roast!
Way back in the archives on the blog there’s a recipe called Stove Top Pot Roast with Mushrooms and Sage, and when I stumbled across it recently, it inspired me to create a slow cooker version of pot roast smothered with mushrooms. The other inspiration for this Low-Carb Slow Cooker Mushroom Lover’s Pot Roast was a new brand of mushroom bouillon cubes that I just had to try in a recipe!
If you don’t have mushroom bouillon cubes or concentrate, I hope you’ll get some before you make this, because that’s what makes the pot roast so flavorful! There are lots of good brands, and if your store doesn’t carry them you can follow the link above and see a variety of options on Amazon.com. The one I used had only 2 carbs in a cube, but check the ingredients if you’re looking for one that’s gluten-free or Paleo. (There are some more photos of mushroom bouillon cubes in the stove top post roast recipe linked above.)
I served this to my niece Kara‘s family, which has mostly mushroom haters, but everyone liked the pot roast and Kara and I enjoyed the mushrooms. Even the seven year old who isn’t a big meat eater ate some of this.I already shared some Low-Carb Menus for Valentine’s Day, but if you didn’t pick one yet I think this pot roast would be a hit with Valentines who love mushrooms.
Dissolve 2 mushroom cubes or 2 T of mushroom stock concentrate in 1/2 cup of water. Trim the chuck roast well and rub with steak rub; then heat the olive oil and brown the meat well on all sides.
Put the meat into the slow cooker, then add the mushroom broth to the frying pan and cook for a minute, scraping off any browned bits from the bottom of the pan. Pour that liquid over the meat and cook on HIGH for 3 hours. Then wash the mushrooms and cut into thick slices.
Put mushrooms over the meat in the slow cooker and cook 45-60 minutes more, or until the meat feels very tender when you pierce it with a fork. Remove mushrooms and meat to the cutting board and strain the au jus. Taste to see if you want to reduce it to concentrate the flavor. Slice the meat and serve smothered with mushrooms, with mushroom au jus to serve over the meat at the table. You could thicken the liquid and make gravy if you prefer, but it’s also great without thickening.

Low-Carb Slow Cooker Mushroom Lover’s Pot Roast
(Makes about 6 servings; recipe created by Kalyn with inspiration from Stove Top Pot Roast with Mushrooms and Sage.)
I used the 6 Quart Ninja Cooker for this recipe, but any smaller slow cooker that will hold the roast and mushrooms will work.
2 mushroom stock cubes or 2 T mushroom stock base + 1/2 cup water (There are a lot of good brands of mushroom bouillon cubes or concentrate; check the label if you need gluten-free or Paleo)
3-4 lb. chuck roast (before trimming), fat trimmed (cut apart as needed to cut out the fat)
1 – 2 T steak rub for rubbing the meat before browning (There are a lot of good brands, but I love Szeged Steak Rub.)
1 tsp. onion powder for rubbing the meat before browning
3/4 tsp. kosher salt for rubbing the meat before browning (Use less if your steak rub has salt.)
1/2 tsp. fresh ground pepper for rubbing the meat before browning
2-3 tsp. olive oil
1 – 1 1/2 lbs. Cremini mushrooms
Put the mushroom cubes or stock base into a glass measuring cup with 1/2 cup of water and microwave until the mushroom base has dissolved into the water, about a minute. Stir to combine.
Trim the roast, removing most of the fat even if you have to cut the roast into sections to get the fat off. (If you like the flavor of beef fat you can trim less vigorously; I prefer it to be well trimmed.) Mix the steak rub, onion powder, salt, and black pepper. Rub all sides of the meat generously with the spice mixture.
Heat the oil in a non-stick or cast-iron frying pan and brown the meat well on all sides. This will take about 5-7 minutes; don’t rush the browning step. When the meat is nicely browned, put it into the slow cooker. Pour the mushroom stock mixture into the frying pan and cook on high for 1-2 minutes, scraping with the turner to remove any browned bits from the bottom of the pan. Pour the liquid over the meat in the slow cooker.
Cook on HIGH for 3 hours. Wash mushrooms and cut into thick slices. Put mushrooms over the meat in the slow cooker and cook 45-60 minutes more, or until mushrooms are cooked and the meat feels tender when you pierce it with a fork. Scoop out the meat and mushrooms with a slotted spoon; put the mushrooms in a bowl and the meat on a cutting board. Strain the juice and taste to see if you want to simmer it to reduce and intensify the flavor. (Mine was very flavorful without doing that. You might want to use the slow cooker to keep the meat and mushrooms warm if you’re reducing the au jus or making gravy.)
Slice the meat, arrange on a platter, and serve with mushrooms and mushroom au jus. (If you don’t care about low-carb you can thicken the au jus with some cornstarch and make gravy.)
