Keto Sous Vide Prime Rib Roast Recipe

If you are doing a keto or low carb diet you probably eat quite a bit of meat.  But, buying better cuts of meat can get pretty expensive.  I received an Anova Nano Sous Vide cooker last year as a gift.  One of the best things about Sous Vide cookers is the ability to make cheap cuts of meat tender and they can make the best keto friendly sous vide prime rib roast so perfectly.

It is guaranteed to be the best you have ever had. Sous Vide Prime Rib can be made with many different cuts of meat.

With a sous vide cooker it’s now easier than ever to have a perfectly cooked prime rib dinner without a lot of the hassle you normally have to go through.

Usually you have to have the prime rib cooking in the oven for several hours. Basting is normally recommended and takes time as well as well as having to suffer with high temperatures opening and closing the oven.

All of this takes away from enjoying your day. On top of all the work you still need to make all of the other sides for the dinner.

Making a Sous Vide Prime Rib Roast

Eliminates the majority of the work entailed with the prime rib itself and ensures that the prime rib meat will come out perfectly tender and medium-rare throughout.

We like to add some extra flavor by applying a rub or paste to the outside of the roast then quickly searing or broiling it to form a nice crust.

I prefer a nice garlic and rosemary flavoring but many people love a horseradish or mustard crust on their prime rib beef. With a Anova Sous Vide cooker it’s easy to make anyway you choose.

This cooking technique can be applied to any kind of roast, from a sous vide prime standing rib roast to a pork roast or a simple sirloin roast or to Pork Knuckles. For some of the tougher cuts of beef you might want to increase the time spent in the sous vide cooker.

I also used grass-fed beef which I’ve found to have better texture when not cooked as long as the supermarket beef but costco meat is quite a bargain and can feed an army. If you’re looking for a place to get grass-fed beef, Carnivore Style has a lot of guides and reviews to help you out.

The Process of Cooking a Good Sous Vide Prime Rib Roast

You first season the meat with any seasonings you want to create a nice base flavor. The flavor injection is so delicious.

I often use a mix of garlic powder, salt, pepper, and ancho chili powder, as well as some fresh rosemary and thyme of sous vide Roast.

Then you place the prime rib roast in the bag and seal it

Cook the prime prime rib for between 5 and 10 hours. I now almost exclusively cook mine at 131°F (55°C) for a nice medium-rare. I wouldn’t go above 137°F (58.3° C) unless everyone at the table like it at least medium.

And remember not to go much below 130°F (54.4°C) for more than a few hours as per the sous vide safety guidelines.

Perfect Sous Vide Prime – Keto Friendly

HIGH-FAT MEAT CAN IMPROVE KETOSIS RATESKetosis is a state where the body burns fat as a source of energy instead of glucose or carbs. The length of time that it takes for an individual to achieve a state of ketosis can vary, but consuming fattier cuts of meat can help to make the transition faster.

The best cuts of meat for a ketogenic diet are those that contain higher levels of fat, since even excess lean protein can interfere with the ability to achieve and maintain ketosis. They also add extra flavor.

Excess protein without fat can be converted into glucose for energy. With a ketogenic diet, the goal is to have ketones from fat as the primary source of fuel.

While consuming very low carbs is essential for achieving ketosis, it can also be beneficial to eat the right cuts of meat, as well as high-quality meat. Grass-fed and pastured meats are higher in nutrients and more beneficial fats, especially since they contain higher levels of the anti-inflammatory omega-3 fatty acids.

Along with the meat selection a good BHB salt with MCT oil like Nutriflair Keto can help kickstart ketosis.


Choosing meat for a ketogenic diet should revolve around how many grams of fat there are per serving. Additionally, fatty cuts of meat can also be cooked in other fats, like lardtallow, avocado oil, gheebutter, or coconut oil, and can be paired with other keto-friendly foods like avocado, eggs, and low-carb vegetables like leafy greens, asparagus, and zucchini.

Prime Rib has always been one of my favorite things to order at a restaurant and you might be surprised how many restaurants use cookers to make their Sous Vide Prime Rib.  Its so juicy and always perfectly cooked.  I’d never tried to make it at home before but I figured I’d give it a shot.

However, when I went to the store the actual prime rib at my local store it was $120, Costco of course is much cheaper if you are a member!!  Luckily, I was able to get the butcher to cut me a more manageable 5 Lb cut of rib. To cook it, I decided to use my homemade Sous Vide setup so I could get the ideal finish level.

It worked out really well! Perfect Keto Friendly Sous Vide Prime Rib. The sous vide prime turned out excellent! It was really tender and medium rare!

Start with a nice cut of prime rib and liberally apply salt and pepper.  Note that prime rib is a little confusing in the sense that prime is the grade of the meat and rib refers to the section which it is cut.  So in reality you will probably end up getting choice rib but that’s besides the point.

I went to my butcher at my local grocery store and asked him for 5 lbs of prime rib to make sous vide prime.

Next, seal the prime rib with your vacuum sealer.

To cook the sous vide, we will submerge it in hot water for 10 hours.  I am using my homemade sous vide machine but you can also buy one from amazon.

I cooked it at 58 degrees which is on the border of medium and medium rare.  If you like it more rare, adjust it down.

Here is After 10 Hours of Cooking

The method doesn’t char the outside of the roast at all so after cooking it, briefly broil it in the oven to char the outside.

After the roasting of the Sous Vide, you can see that the roast is a perfect 133 F via my thermapen. By the way, I just got this thermometer and it is by far the best thermometer I’ve ever had. It’s super fast to read and waterproof.

Sous Vide Prime Roast is a family favorite for any occasion and also create sous vide Mexican food iteams.
