How to cook keto slow cooker pot roast
Step 1: Sprinkle both sides of the chuck roast with salt and pepper. Heat oil in a large skillet over medium high heat and sear the roast on both sides until browned. This step adds flavor but can be skipped if you are short on time.
Step 2: Transfer the roast to the slow cooker. Add the balsamic vinegar to the pan and turn the burner down to medium-low. Scrape up and browned bits on the bottom of the pan and simmer the vinegar for 1 minute. Pour this over the top of the pot roast in the slow cooker. Add beef broth, sliced onions, garlic, and mushrooms.
Step 3: Cover and cook on low for 7 to 8 hours or on high for 5 to 6 hours until fork tender. Add zucchini during the last 30 minutes so it softens without becoming mushy.
Step 4: Remove the roast carefully and break into bite sized chunks. Spoon pan drippings over the top and garnish with fresh parsley.
Substitutions and Variations
- Leave out mushrooms and zucchini to reduce carbs further.
- Add whole radishes or small amounts of carrots if desired.
- Use avocado oil instead of canola oil.
- Skip searing if you need a true dump and go option.
- Make a gravy from the pot roast juices. After removing the roast, strain the pan drippings. Whisk in ¼ teaspoon xanthan gum and salt and pepper to taste. Simmer until it starts to thicken, and drizzle over the top of the pot roast.
- Add herbs- add a bundle of fresh herbs like fresh rosemary and thyme to your pot roasts.

No. It is not recommended to cook a frozen roast in a slow cooker because the temperature rises too slowly to safely kill bacteria. For food safety, thaw the roast completely before placing it in the crock pot. If you need to cook it from frozen, use the oven, stovetop, or a pressure cooker instead.

What cut of beef is best for keto pot roast?
Chuck roast is ideal because it becomes tender and juicy after slow cooking.
Can I skip searing the roast?
Yes. Searing adds flavor but the recipe will still work if you place everything directly in the slow cooker.
How do I thicken keto pot roast gravy?
Use a small amount of xanthan gum to thicken the pan drippings instead of flour or cornstarch.

Instructions
- Sprinkle both sides of the roast with salt and pepper.
- Heat a large skillet over medium-high heat. Add the oil. Sear the roast on the top and bottom.
- Remove the roast and add it to the slow cooker. Add the balsamic vinegar to the pan the roast was seared in, and turn the burner down to medium-low. Scrape up and browned bits on the bottom of the pan and simmer the vinegar for 1 minute. Pour this over the top of the roast in the slow cooker.
- Add the beef broth, sliced onions, minced garlic, and halved mushrooms to the slow cooker.
- Cover and simmer on low for 7-8 hours or high for 5-6 hours. Add the zucchini slices to the slow cooker and simmer until soft, which will take about 30 minutes.

Notes
- The mushrooms and zucchini can be left out of the roast if you want to reduce the carbs even more.
- Other great low carb veggies to add would be carrots (in moderation) or whole radishes.
- If you're in a hurry, the searing step can be skipped. Just add everything to the slow cooker and proceed with the recipe.
- Likewise, if you have extra time, we recommend you saute the minced garlic and onion before adding it to the pot to bring out extra flavor.
- To make a gravy from the pan drippings, after removing the roast, strain the pan drippings. Whisk in ¼ teaspoon xanthan gum and salt and pepper to taste. Simmer until it starts to thicken, drizzle over the top of the roast.
