How to Make A Keto Herb Butter Roast

When it comes to making a roast, the most important part is choosing the right cut of meat. An eye of round roast is best because it’s lean yet has a good amount of marbling.

Marbling in meat refers to the white striping within the meat that comes from fat deposits in the muscle tissue. We specifically want this fat marbling to create flavor, but it also helps keep our keto roast nice and moist!

If you can’t find an eye of round roast, a chuck roast would work as well. It will have a bit more marbling and require less baking time. Other cuts that work well are top round, rib-eye roast, and bottom round roasts.

It’s important to also remove any of the thin membranes from your cut. This will make it easier to slice and eat after it’s cooked. You can have this done for you at the meat counter at most grocery stores!

Prepping this keto-friendly roast is really very simple. Just rub generously with salt, freshly cracked pepper, and herbs and wrap in plastic wrap. The hardest part is waiting until the next day to roast it!

The next day, you’ll remove the cling wrap and cover the roast in the herb butter and bake at 350 degrees for a little under an hour or until it reaches an internal temperature that you desire. For the most tender slices of roast, medium-rare 135-140 degrees is best but feel free to adjust for your preference.

When your roast is almost done, turn on the broiler for about 5 minutes to get a beautiful brown crust on top. Be sure to keep an eye on it at this stage, things move quickly under the broiler!

How to Make Herb Butter

What takes this roast from good to great is, of course, the herb butter. It’s one of the greatest perks of the ketogenic diet. Being able to enjoy the best things in life, like butter!

Joking aside, fat as we all know is where all of the great flavors come from and this roast has plenty of it! That’s what makes it a perfect keto-friendly option. Lots of fat equals tons of flavor and staying satiated longer, what more could you want from a dish?

Herb butter is easy to make, keto-friendly, and can be made days before you decide to use it for this roast. It’s also great on pretty much anything including grilled veggies!

All you need to make this herb butter is softened butter, fresh chopped herbs (you can also use dried), salt, and pepper.

Mix these ingredients well together in a small bowl and you’ve got yourself some herb butter. I told you it was easy!

I add a layer of onions and mushrooms on both sides of the roast which basically makes its own sauce as the mushrooms and onions cook in the meat juices and butter.

Our family came to the keto diet looking at it from a Christian perspective, it’s the filter we choose to see from. When we decided to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.

To say we needed God’s intervention is putting it mildly. When we followed the Holy Spirit’s lead to embrace the ketogenic diet and to combine it with our faith, we got on the path to real transformation.

This Keto Herb Butter Roast Beef is easy to make and will be a hit at your next party. The herbs combine beautifully with garlic and butter in the oven to create an irresistible, moist, tender roast of round beef.


  • 5 pound eye of round roast, with the thin membrane removed
  • 1 3/4 teaspoons sea salt
  • 1/2 teaspoon freshly cracked black pepper
  • 2  teaspoons fresh rosemary, chopped
  • 1/2 teaspoon fresh thyme, chopped
  • 1 large onion, sliced
  • 1 cup sliced mushrooms

Keto Herb Butter

  • 1/2 cup butter, softened
  • 1 1/2 teaspoons salt
  • 1/2 teaspoon freshly cracked black pepper
  • 1 1/2 teaspoons fresh rosemary, chopped
  • 1 teaspoon fresh thyme, chopped
  • 6 cloves of garlic, minced


  1. In a small bowl, combine the salt, pepper, and herbs. Rub this mixture all over the roast and then wrap the entire thing in plastic wrap. Place in the refrigerator overnight or for at least 8 hours.
  2. Preheat the oven to 350 degrees. In a small bowl, prepare the herb butter by combining the butter, herbs, garlic, salt, and pepper.
  3. Remove the roast from the refrigerator and place it on a large baking pan that can accommodate the roast and mushrooms and onion. Spread the herb butter all over the top of the roast and add the sliced onions and mushrooms around the roast.
  4. Place in the oven and bake for approximately 45 minutes, until the internal temperature reaches 10 degrees under your desired temperature. Set the oven to broil and cook for an additional 5 minutes until the roast is browned and reaches your desired doneness. I recommend 135-140 degrees for medium-rare.
  5. Remove from the oven and allow the roast to rest for 10 minutes before slicing thinly and serving.
  6. Store leftovers in the fridge for up to 3-4 days. Freeze in an airtight container for up to 3 weeks.


If you can't find fresh herbs, dry herbs will work fine as well.

You can also use chuck roast, bottom round, or top round roast, ribeye roast in this recipe. Cooking times will vary depending on the meat you choose.
