This keto Instant Pot butter beef recipe is full of flavor, tender to eat, and perfect as a keto beef recipe, on a sandwich, or over mashed potatoes. For those of you trying to eat keto or low-carb, this is also a perfect beef roast recipe for your diet plan. This butter beef roast is like the Mississippi pot roast recipe in many ways with the stick of butter, banana peppers, and zesty seasonings.

We all have an Instant Pot in our pantry or cabinets. Pull it back out because if you want a keto pot roast, this recipe makes it fast! This was a recipe I made the very first time in the Instant Pot I made where my husband looked at me and said, "You could make this again anytime".

Low-Carb Instant Pot Butter Beef Ingredients

Five ingredients get you on the way to the most flavorful and tender beef roast you will have had in a long time. The butter beef roast is similar to the Mississippi beef roast but the ingredients are slightly different. Here are the ingredients you will need to make this keto beef roast recipe.

• Ranch and Italian salad dressing mix - Yes, both ranch and Italian seasonings for this recipe. No need for gravy or au jus like in the Mississippi pot roast. These two flavors together are perfect.
• Banana pepper rings - Mild peppers or hot pepper rings depending on your heat preference. Like hot spicy? Then get the hot banana pepper rings. Don't love spicy food, go for the milk pepper rings.
• Butter - A whole stick of real butter is what brings the fat levels up in this recipe to make sure it gets the keto blessing.
• Beef Chuck Roast - I prefer chuck roast for this recipe. It has nice back fat plus intermuscular fat to make for a simple yet delicious low-carb beef roast recipe.

This roast is not at all dried out thanks to the stick of butter used in the recipe. Tangy and savory with just a little bit of spice makes this Instant Pot butter beef a melt in your mouth Instant Pot roast.

How to Make Keto Instant Pot Butter Beef Roast

Start by setting your Instant Pot to saute or brown. When the pot is hot, add a tablespoon of olive oil and sear the roast on both sides. Shut the pressure cooker off. Then add the remaining ingredients to the Instant Pot. The inspiration for this recipe comes from the Mississippi beef roast recipe, but I had to reinvent it to be lower carb.

The ingredients I used for the Instant Pot butter beef are banana pepper rings, zesty Italian seasoning, ranch dressing mix and a stick of butter. I use about a quarter cup of the pepper ring juice as well. I just pour it all over the top of the beef roast along with a cup of water and call it good. Then place the lid on the Instant Pot and lock it into place. Set the vent valve to seal and then put it on manual for 60 minutes. For reference, it took my Instant Pot about 15 minutes to pressurize. My roast was not fully thawed. When the Instant Pot is finished and shuts off, release the pressure.

Then start shredding the beef or cutting it apart. I use a pair of salad scissors on mine to help the process. Note - if the beef for some reason is not done or tough, I have been known to put the lid back on and pressurize for another 10-15 minutes.

I placed my Instant Pot butter beef on top of pureedcauliflower while my kids made sandwiches with Hawaiian sweet rolls and put some over mashed potatoes too.

There isn't much liquid at the bottom of the Instant Pot for a gravy, but there is enough to have the juices poured over top of the Instant Pot butter beef.

There will not be leftovers of this low-carb beef roast. Trust me.

Variations to the Instant Pot Butter Beef

This method of making a low carb pot roast can be altered for different flavors that are still keto diet compatable.

• Red Wine and Mushroom Beef Pot Roast - Use beef broth with red wine in place of the butter and mushrooms in place of the pepper rings for a rich beef roast recipe. Checkout the slow cooker red wine and mushroom beef roast recipe.
• Add veggies - Mix in parsnips, turnips, rutabaga, Brussels sprouts, cauliflower, or others for variety.
• Swap the meat - Use pork roast, turkey breast, or venison roast instead of a beef roast.
• Make it saucy - When finished, remove the meat and thicken the cooking liquid with xanthan gum.

Tips for Making Keto Instant Pot Butter Beef

• I prefer using chuck roasts for this recipe, but any beef roast can be used.
• Every roast thickness can be different. If the roast is still tough, try 15 minutes longer under pressure after cutting into smaller pieces.
• Don't overdo the pepper juice. It can make the roast too salty with the salad dressing mix.
• Don't have an Instant Pot, try the crock pot butter beef recipe. It is just as good and is still the best keto beef roast recipe.
