Slow Cooker Keto Pot Roast

This keto pot roast is made with onion soup mix and 3 other ingredients to make a savory beef roast. Making keto pot roast in the slow cooker creates tender meat with little effort. And I have a delicious keto mashed cauliflower dish to go with it if you are on a low carb diet to create the perfect keto comfort meal. Each serving has only 4.4g net carbs!

I’m sure you have all made that classic pot roast in the crockpot along with onion soup mix and canned soup. It’s so easy to basically mix dump and set it on low and slow for a hearty and comforting dinner.

Well today I decided to make this keto pot roast in a similar way. I used onion soup mix but I didn’t use any canned soups which tend to be higher in carb. I put it in the slow cooker and the result was tender, juicy and super flavorful beef roast with rich gravy.

I also made some mashed cauliflower to take the place of regular mashed potatoes and covered it with the gravy from the roast. It was an awesome keto dinner and my family loved it.

Recipe ingredients I used.

Below you can see the simple ingredients I used for this recipe. I had a boneless beef chuck roast on hand, butter, balsamic vinegar, onion soup mix and Better than Bouillon beef base. That’s all you need.

You can use different cuts of meat for this recipe like round or rump roasts but chuck roasts have a lot of marbling of fat and that really adds to the flavor to the meat. 

I am constantly singing the praises of Better than Bouillon bases because they are fantastic for soup, casseroles and dishes like this. They add so much flavor so I high recommend you buy some.

But if you don’t have any you can use regular beef bouillon or beef broth. You can also add some beef stock or broth instead of the water for more flavor. 

Also if you don’t care about carbs feel free to add some chopped carrots, celery, yellow onion, potatoes or whatever you would regularly cook along side the roast for a one dish meal.

How to make a keto pot roast in the slow cooker.

Step 1: Spray the crockpot with nonstick cooking spray and set aside. Heat up the butter in the microwave then pour it into a mixing bowl along with the soup mix, water, vinegar and Better than Bouillon. Mix well.

Step 2: Place the chuck beef roast into the crockpot and pour the soup mixture over top. Place the lid on a cook for 6-8 hours on low or 4-6 hours on high. The meat with be nice and tender when it’s done. Cooking time may vary.

I used a 3 pound roast and it took me 4-5 hours on high. Normally I would have cooked it on low all day but I needed to take pictures of it for this post.

Step 3: When the meat is done, slice it and place in a large serving bowl. Pour the gravy over top and serve.

If you want a thicker gravy you can use a keto thickener like xanthan gum. If you are not on a low carb diet you can use traditional flour. I thought it was fine as it was.

You can also serve this low carb pot roast with mashed potatoes if you don’t care about carbs. Use the cooking juice as a keto gravy to top your potatoes.

I made cauliflower mash for me and regular mashed potatoes for my family to make this more of a complete meal.

How to make keto cauliflower mash to go with the roast.

You can easily make cauliflower mash in the blender. All you need is a head of cauliflower, butter, salt and black pepper. So about 15 minutes before dinner time make the cauliflower mash.

1. Cut up your cauliflower into florets and place in a microwaveable bowl. Rinse with water and drain the extra water out. Add the butter and microwave for up to 10 minutes until fork tender.
2. Check on it half way and stir to get the butter all through it. Test the florets to see if a fork can easily pierce them. If not cook for a few more minutes.
3. Once the cauliflower is cooked, add to a high speed blender or food processor and blend on high until you reach a mashed potato consistency.
4. Season with salt and pepper if you wish. If it is thick you can thin with a tablespoon of water, heavy cream or almond milk.
5. If it’s too thin you can try adding a bit of cream cheese or shredded cheese to thicken it. The cheese will change the flavor a bit and I just like to keep it simple because I used the gravy on top to add flavor.
