How long to cook a 4 lb outside round roast?

It's impossible to give you an exact cooking time for a 4 lb outside round roast without knowing how you want to cook it. Here's why:

* Cooking Method: Roasting in the oven, slow cooking, or using a pressure cooker all have different cooking times.

* Desired Doneness: Do you want it rare, medium-rare, medium, or well done?

* Temperature: Oven temperatures can range from 325°F to 450°F, each impacting cooking time.

Here's a general guideline for roasting a 4 lb outside round roast in the oven:

* 325°F: Expect around 2.5-3 hours for medium-rare to medium doneness.

* 350°F: Expect around 2-2.5 hours for medium-rare to medium doneness.

Tips for Success:

* Use a meat thermometer: The most accurate way to determine doneness is with a meat thermometer. Aim for 135°F for medium-rare, 145°F for medium, and 160°F for well done.

* Rest the meat: After cooking, let the roast rest for 15-20 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
