You’re planning to prepare a roast for dinner, but you forgot to defrost it. I hate it when that happens. But, you have a pressure cooker, and/or instant pot. Problem solved. So, you ready… Let’s get into the kitchen.
How Many Minutes Per Pound Will It Take To Cook A Frozen Roast Beef?
The weight of the beef determines how long it will take to cook.
Roast beef is served at 135°F for medium rare and 145°F for medium.
Roast beef should be cooked for 30-35 minutes per pound for medium-rare and 40-45 minutes per pound for medium.
The following chart illustrates how long it takes to cook a frozen roast beef to the following temperatures:

Tips For Cooking Frozen Roast Beef
When preparing a frozen roast beef, there are steps you should take that are even more crucial than when preparing a fresh roast beef.
Follow these instructions when preparing your frozen roast beef:
Season The Meat
Make sure to heavily season the roast beef. Use salt, pepper, and any additional seasonings or herbs you prefer.
Thyme, rosemary, sage, oregano, butter, garlic, mustard seed, and other common herbs and spices are used to flavor roast beef.
Using chicken or beef broth when cooking roast beef is another way to guarantee its tenderness and flavor.
Place the piece of beef on a rack over a roasting pan, then pour broth into the pan’s bottom. For added flavor, you can also add aromatics like onion, garlic, and herbs to the broth.
