How long do you cook a 2.64lb sirloin roast?

The cooking time for a 2.64lb sirloin roast will depend on the desired doneness. Here is a general guideline for cooking a sirloin roast:

1. Preheat your oven to 425 degrees Fahrenheit.

2. Pat the roast dry with paper towels and season it with salt, pepper, and any other desired herbs or spices.

3. Place the roast in a roasting pan and cook it in the preheated oven for 20 minutes.

4. Reduce the oven temperature to 375 degrees Fahrenheit and continue to cook the roast for an additional 25-30 minutes per pound, or until it reaches your desired doneness.

5. Use a meat thermometer to check the internal temperature of the roast. The internal temperature should be 125 degrees Fahrenheit for rare, 135 degrees Fahrenheit for medium-rare, 145 degrees Fahrenheit for medium, and 155 degrees Fahrenheit for well-done.

6. Let the roast rest for 10-15 minutes before slicing and serving.

Please note that these times are approximate and may vary depending on the specific oven and the cut of meat. It's always a good idea to use a meat thermometer to ensure that the roast is cooked to your desired doneness.
