How to Make Low Carb Instant Pot Roast

Let’s get cooking! You’re going to want to sear the roast before you cook it, so hit the “saute” button on your Instant Pot and allow it to start heating up.

Next thing you’ll do is take some paper towels and pat down the roast really well, which will ensure your seasonings stick and that it gets a good sear.

Because much of the flavor from this Keto pot roast occurs during the searing phase, you’ll want to cut your roast into several large chunks. This allows more surface area for browning which means more flavor!

Next, you will season each piece generously with salt and pepper.

Once the roast is seasoned, add just enough olive oil to coat the bottom of the pot and allow to heat.

Carefully add the beef and sear each piece, turning them as you go. You want to make sure every side is seared. Depending on the size of your roast, you may have to do this in batches. Remove the roast from the pot and set it aside.

Now it’s time to add in the onions with another dash of salt and pepper, and sauté for about 2 minutes. Add in the garlic and continue sautéing for another 20 seconds.

Once the onion and garlic have been sautéed, add in the white wine to deglaze the pot, making sure you scrape up the brown bits of flavor.  

The wine is optional, but it truly gives this low carb pot roast and gravy a great depth of flavor.  You can certainly omit it and to do so, you just deglaze the pot with a little chicken stock.

After you have scraped up all those little bits of deliciousness, stir in the chicken stock, tomatoes, tomato paste and Herbs de Provence.

Place your beef back into the Instant Pot and lock the lid in place. Set the valve to the “seal” position.

Turn the “pressure cook/manual” setting to high pressure and set the time based on the size roast you have. You can figure cooking time on being 20 minutes per pound. Walk away and let the magic happen!

While the roast is cooking, you can start making this yummy Cheesy Mashed Cauliflower.

When the time on the Instant Pot is up, allow it to naturally release for 20 minutes or longer, then switch it to manual release.

Open the lid and just take a look at those beautiful chunks of meat! Remove them from the pot and set aside. If you want to pull them apart, you won’t even need a knife, they will fall apart that easily!

Next, let’s get started on that Keto gravy! Right into the Instant Pot, add the Mascarpone cheese and Xanthan Gum and mix with all the pan juices.

For the easiest and best results, use an immersion blender to make sure everything is mixed well.

However, if you don’t have an immersion blender, just pour everything into your food processor or Vitamix and blend it together.

This savory low carb gravy will be thick, rich and loaded with flavor.

Because this recipe makes plenty of gravy, you’ll want to be sure and save the leftovers to enjoy later over these amazing low carb Bacon Cheddar Drop Biscuits.

Serve with your Cheesy Mashed Cauliflower or one of your other favorite low carb sides.

And there you have it, the absolute best pressure cooker pot roast with Keto gravy you will ever taste!

Tips for Making the Perfect Low Carb Instant Pot Roast

• The most important step of perfecting your Instant Pot roast, is to start off with a good cut of meat. Chuck roast is the most popular and certainly the most favored cut for making pot roast due its marbling. Other cuts such as a top round or rump roast are alternatives, but they are leaner cuts which can sometimes make a drier roast.
• Make sure you season the meat prior to searing. This seals in the flavor and helps in browning.
• Store bought chicken stock is perfectly acceptable to use for your roast. But, keeping homemade Chicken Stock in the freezer to use when making roast and many other low carb recipes is truly worth the effort. The flavor can not be beat, and it can be made in an hour in your Instant Pot!
• Though the wondrous smell of the pot roast cooking may tempt you to manually release after cooking, by allowing it to slow release for at least 20 minutes, the meat will relax and become more tender.
• To freeze leftover Keto pot roast, just place the pieces into a freezer safe container and completely cover it with the gravy or other cooking liquid. Make sure to label the outside of the container with the date and freeze up to 4 months.
