Keto Prime Rib

My recipes are grain free, refined sugar free and most are dairy free. My son’s favorite meal is prime rib. It’s expensive if you order it in a restaurant. It is cheaper to make this delectable savory dish at home. I don’t know why so many are afraid to make this dish. It really is not that hard. If you don’t have a digital meat thermometer get one. It is well worth the money so that you don’t overcook your prime rib. Medium rare is my goal. This means that the end pieces will be well done or almost well done.

First, you will need to choose a bone in roast or bone out. If you get a bone out roast it might be called a standing rib roast or an eye of rib roast or rib roast. I do think that the roast tastes better with the bone in. I do prefer to get bone it as I use the bones to make a bone broth. If you are not ready to make a bone broth store your bones in a ziplock plastic bag and store in the freezer. This time I couldn’t find a bone in Prime Rib so all the pictures are of a bone out Prime Rib.

The day before I take the prime rib out of the fridge and out of the plastic wrap. I rub pink salt all over the outside of the roast and press into the roast. I then tightly wrap the roast in plastic wrap and place inside and a container of some sort to spare my fridge from any spillage. Place inside the fridge.

1 serving is 8 oz of cooked meat per adult.



8 lb prime rib no bones

2 – 4 tablespoons salt

The day before remove the prime rib from the fridge and rub with salt. Next, wrap the prime rib in plastic wrap and place inside a 2-gallon size plastic bag. Place inside a casserole dish (to spare your fridge any blood or mess) and put back in the fridge.

Spice Rub

2 tablespoons salt

1 teaspoon pepper

1 tablespoon onion powder

1 tablespoon garlic powder

1 teaspoon parsley

1/2 teaspoon celery seed

1 tablespoon paprika

1/2 teaspoon smoked paprika

1 teaspoons rosemary

1 teaspoon oregano

1 teaspoon tarragon

2 cup homemade beef broth or store bought

Information: Remember to allow time for the roast to come to room temperature before cooking. Get all of the seasonings and measure them out in a bowl. Stir until well combined. There may or may not be Prime Rib Rub leftover depending on how much you rub on. After making the rub remove the roast from the plastic. I lay down two sheets of plastic wrap slightly overlapping as it makes for easier cleanup. I place the roast on the plastic wrap and rub and press the prime rib rub on the roast on all sides. If you bought a bone in roast make sure the bone side gets rub too. Place your roast in a deep sided pan like you would use for lasagna. Make sure the pan is bigger than the roast. Place the roast fat side up regardless whether you have a bone in or bone out roast. As the roast cooks the fat will seep down into the meat and make it more flavorful. Using a digital meat thermometer place it into your roast as far as it will go. My thermometer beeps when it hits the desired heat.


Preheat oven to 450* F. Place spice rubbed Prime Rib Roast fat side up inside a deep dish pan with high sides in a preheated oven. Pour two cups of beef broth in the bottom of a pan to use for later if you want gravy or au jus. Roast for 10 minutes at 450* F. After 10 minutes turn down the temperature to 350* F. Cook at 350* F for the remaining time approximately 1 1/2 hours or until digital thermometer reaches 120 – 125 for medium rare. Once your roast hits your desired temperature remove from oven and let sit 15 – 20 minutes. Your roast will continue to go up in temperature as you wait. Do not cover as the crust on the roast will become soggy.
