How to Make the Most Tender Slow Cooker Roast Beef

While the roast beef has to be slow cooked for a little over eight hours, it’s incredibly quick to get everything ready to go in the morning. Start by placing your chopped onion, minced garlic, peppercorns, bay leaf and one cup of water in the slow cooker. I’ve been using this same crockpot for years without fail.

Using onion and garlic is a great way to add an immense amount of flavor into this recipe right from the get-go, and they’re both excellent sources of allicin as well. Allicin is the compound responsible for giving them their distinctive taste along with many of their associated health benefits like boosting your immune system, lowering blood pressure, and helping to prevent atherosclerosis.

Next, use a small bowl and combine your salt, dried thyme, paprika, black pepper, and garlic powder. You’ll be using this mixture as a rub for your crockpot roast beef, and believe me when I tell you, it really helps to take this recipe and make it into an almost gourmet style meal!

I love adding paprika into the mix as well because it’s one of my favorite herbs to cook with. In fact, it’s an incredible match for the keto diet as well as studies have indicated that paprika helps to both prevent and improve obesity-related insulin resistance, making it a great herb to use for anyone trying to manage their weight.

Add some olive oil into a large skillet and then take your mixture of herbs and spices and pat it evenly on all sides of the roast beef. Sear your beef on all sides for a few minutes before transferring it into the slow cooker.

Use the balsamic vinegar to deglaze the pan and then pour it all over top of the roast. That’s all there is to the keto roast beef prep, now simply leave it to cook for eight hours.

Before you serve it, you’ll want to make the homemade gravy by straining the cooking juices out of the crockpot and into a saucepan after removing the roast beef.

Next, in order to make the gravy even more appealing for keto fans, add in some cream cheese and heavy cream to add plenty of flavorful fats into the mix. Simmer the gravy until it’s warmed up and then go ahead and serve it alongside your roast beef meal.

Slicing the roast beef before you serve it is so easy due to how incredibly tender it turns out. The beef is already incredibly flavorful thanks to the savory mix of herbs and spices and then slow cooking it in the garlic, onion, and peppercorn mix — it’s so yummy you could just eat it as is!

However, I like to smother mine in the gravy mixture because it adds even more healthy fats to my meal and it tastes amazing.

P.S. If you’re looking for something just as soul-satisfying and have a little extra time to make them, you’ll love this keto crockpot Swedish meatballs recipe:

  1. I made this as directed for my husband who is following the Keto diet and he absolutely loved it. Making a second time today 🙂

    • Sometimes that happens! The best way to make it blend smoothly is to ladel a small amount of gravy into a bowl with the cream cheese and slowly add in more and more as you stir. That will make the cream cheese blend without chunks in the roast beef gravy.

      Also try bringing your cream cheese closer to room temperature before adding so it isn’t super cold.
