The cooking time for beef in an electric pressure cooker varies depending on the cut and desired doneness. Generally, cooking times range from 15 to 45 minutes. For example, a 1-inch thick steak can be cooked to medium rare in about 15 minutes, while a 3-inch thick roast beef may take up to 45 minutes to reach the desired level of doneness.

The reason for the variation in cooking times is due to the different cooking temperatures and pressures that electric pressure cookers can achieve. These cookers typically operate at temperatures around 250°F (121°C) and pressures up to 15 psi (pounds per square inch). The high pressure and temperature combination helps to cook the beef faster than traditional cooking methods like boiling or slow cooking.

According to the National Center for Home Food Preservation, cooking times in electric pressure cookers are approximately 70% of the cooking times in a conventional oven. This is because the pressure and heat combination accelerates the cooking process. For instance, a 1-inch thick steak that would take about 20 minutes to cook in a conventional oven can be cooked in about 14 minutes in an electric pressure cooker.

Additionally, the type of beef and its cut also play a significant role in cooking times. tougher cuts like brisket or chuck require longer cooking times to tenderize the meat, while tender cuts like ribeye or sirloin can be cooked faster. The fat content of the beef also affects cooking times, as higher fat content can slow down the cooking process.

In summary, the cooking time for beef in an electric pressure cooker ranges from 15 to 45 minutes, depending on the cut and desired doneness. The high pressure and temperature combination of electric pressure cookers allow for faster cooking times compared to traditional methods, making them a convenient option for busy cooks.
