How long do you cook beef round sirlion?

You can't cook beef round sirloin. That's because round sirloin is not a cut of beef.

"Sirloin" refers to a specific section of the beef, usually implying a more tender cut like strip steak or top sirloin. "Round" refers to a different part of the animal that is generally tougher.

Here's what you might be looking for:

* Beef round roast: This is a very common cut of beef, and the cooking time will vary depending on the size and method. A 3-4 pound roast will typically cook for 2-3 hours at 325 degrees F.

* Beef round steak: These can be tough, but they are delicious when cooked low and slow. A 1-inch thick steak will cook for about 1-1.5 hours at 300 degrees F.

If you're unsure about what cut you have, check the label or ask your butcher. They will be able to guide you on the best cooking method and time for your specific cut.
