Pot roasts are one of those comfort foods that I always look forward to when the weather starts to cool down. I’m not a huge fan of potatoes so instead I opt to make my pot roast with radishes instead. 

By replacing the potatoes with radishes it’s an easy way to reduce the carbohydrates in dish. We also don’t add cornstarch to our pot roast so that’s another way to reduce the carbs in our meal.

And because I don’t always remember to throw everything into the slow cooker before a long day at work, I love using the Instant Pot to make this pot roast tender and delicious in a fraction of the time.

How to cook a pot roast

Traditionally a pot roast is a fatter cut of beef sauteed in a pan to brown it. Then it is slowly cooked in an oven, pressure cooker, or crock pot for 8+ hours. Vegetables, herbs, spices and liquid are also added to it. Our keto pot roast recipe is full of flavor, but takes a fraction of the time to make and makes less dirty dishes by using an instant pot. 

How to make a pot roast?

To make a pot roast you need to select a fatter cut of beef. Our recipe calls for a beef chuck roast, but other visibly fatter cuts of beef will be a good pot roast meat. These cuts are large and often cheaper because these have more fat than expensive, leaner cuts of beef.

Once you have selected your beef you need plenty of non-starchy vegetables, herbs, and a couple other ingredients. For example, our easy instant pot recipe uses radishes, garlic, and rosemary.

Why is my pot roast tough?

If your pot roast is too tough and still has plenty of liquid it likely needs to cook longer. A properly cooked pot roast should easily tear apart with a fork. Another reason a pot roast is tough is that it has been overcooked and has dried out. However, our easy instant pot recipe makes it easy to not overcook. 

Why is my pot roast chewy?

If your pot roast is chewy it is undercooked. The fatter cuts of beef for pot roasts have a lot of connective tissue, which takes time to break down. Cooking for additional time should make the pot roast meat easily fall apart.

Can I overcook my pot roast?

Even when cooking slow and at a low temperature, it can still be overcooked. An overcooked pot roast will become dry and much of the liquid will be gone. This is why it is important to check your pot roast and keep track of how long it has been cooking. The thicker the meat the longer it will take to cook it entirely.  

What temperature should my pot roast be?

The internal temperature varies depending on how done you want your low carb pot roast. The minimum internal temperature should be 145 degrees Fahrenheit for medium rare. For medium it would be 160 degrees Fahrenheit.  

Can you cook frozen meat in instant pot?

An instant pot is a versatile kitchen tool. It has many different settings and methods of cooking. An instant pot can cook frozen meat, but it will take more time to reach the proper temperature. It is better to let the pot roast meat thaw in the refrigerator before cooking.

How long does it take to cook meat in an instant pot?

The cook time of meat in the instant pot depends on the type and cut of the protein. The cook times for various meats range from 5 minutes to an hour. Our keto instant pot pot roast recipe takes a little under an hour after browning in it. 

Does pot roast need to be covered in liquid?

A pot roast does not need to be covered in liquid while cooking. Our low carb pot roast recipe only requires 1 cup of beef broth. While cooking the meat more juice will form, which you can eat with your food. You can also fill it up with more liquid, if you want more leftover keto pot roast juices. 

How do I know when my pot roast is done?

The pot roast is done if it has reached the internal temperature you desire. In addition, the meat should tear apart easily with a fork if it has cooked long enough. The vegetables will be soft and you can add the pot roast juices to your dish. 

Pro Tip: You will often have a lot of leftovers so plan to use those within a couple days. 

Pro Tip: Substitute radishes with other non-starchy vegetables such as broccoli, cauliflower, or Brussels sprouts. You could also use a mix of in-season vegetables for your keto pot roast.
