What beef cut to use for keto pot roast?
When making this recipe, I always use a 3 lb. chuck roast that I get at the meat counter at Whole Foods.
Chuck roast is perfect for slow cooking. It’s a tough piece of meat, but it’s very flavorful and well-marbled, and slow cooking makes it very tender.
I usually make this recipe with store-bought beef broth. You can use red wine instead, or half broth and half wine. If you happen to have homemade bone broth, that would be perfect.
Do you have to brown the meat first?
No. I’ve experimented with browning the meat before placing it in the slow cooker and have found that it makes very little difference to the final outcome, so I skip this annoying step. Although it won’t hurt to do it, of course, if you have the patience.
How long does it take to cook a 3 lb. roast in the slow cooker?
You can cook the beef in the crockpot on LOW for 7-8 hours. I actually prefer to cook it for 7 hours, as I find that it sometimes dries out after the full 8 hours.
Do you need flour to thicken the gravy?
Not necessarily. You can thicken any gravy, if you’re patient, by simply cooking it and reducing some of the liquid.
If you want it to happen faster, while keeping the pot roast keto and gluten-free, I suggest mixing 1 tablespoon of organic cornstarch with 1 tablespoon of cold water and stirring that into the gravy.
The cornstarch will only add 7 grams of carbs for the entire recipe. You can also use konjac flour as a thickener. Follow the directions on the package, but probably no more than 1/2 teaspoon (it’s a very powerful thickener) mixed with cold water.
What to serve with keto pot roast?
What about leftovers?
Leftovers keep well for up to 4 days in the fridge. They do tend to easily dry out when reheated, so it’s best to reheat them covered in the microwave, on 50% power.
keto Pot Roast
- 3 lb. boneless beef chuck roast
- 1 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 1 medium onion, sliced
- 2 tablespoons minced garlic
- 1 bunch parsley
- 1 cup beef broth (or red wine)
- Strained cooking juices
- 1/2 teaspoon kosher salt
- 1/4 teaspoon black pepper

- Place the roast in the slow cooker pan and add the sliced onion, garlic and parsley. Pour the beef broth (or wine) on top.

- Remove the slow cooker pot roast to a plate. Set the slow cooker to WARM. Strain the cooking juices into a glass measuring cup, then return the beef to the slow cooker and cover, to keep warm while you make the gravy.
- Use a spoon to skim the fat layer off the top of the cooking juices. Season with 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper. Transfer to a medium saucepan. Heat over medium heat, and continue to simmer, whisking occasionally, until reduced into a rich sauce, about 10 minutes.
- Flake the beef with a fork. Distribute evenly among plates lined with mashed cauliflower. Spoon 2-4 tablespoons of gravy on top of each plate and serve.
