How long to cook a 15 lb rolled bottom round roast?

It's impossible to give you an exact cooking time without knowing your preferred level of doneness and your cooking method. Here's why and how to determine the best cook time:

Factors Affecting Cook Time:

* Doneness: Do you prefer rare, medium-rare, medium, medium-well, or well-done?

* Cooking Method: Roasting in an oven, slow cooking, or grilling all have different heat levels and timings.

* Oven Temperature: Higher temperatures mean faster cooking times, but can also lead to dryness.

* Roast Shape and Size: A rolled roast cooks differently than a whole bottom round.

* Bone-in or Boneless: Bone-in roasts take longer to cook.

General Guidelines:

* Oven Roasting: Plan for about 15-20 minutes per pound at 325°F for a medium-rare roast. Adjust the time for your desired doneness.

* Slow Cooking: A 15 lb roast could take 8-10 hours on low or 4-6 hours on high.

* Grilling: You'll likely need to break a 15 lb roast into smaller pieces to grill effectively.

How to Determine the Best Cook Time:

1. Use a Meat Thermometer: The most accurate way to tell when your roast is cooked is to use a meat thermometer. Insert it into the thickest part of the roast, making sure it's not touching bone.

2. Check for Doneness:

* Rare: 125-130°F

* Medium-Rare: 130-135°F

* Medium: 140-145°F

* Medium-Well: 150-155°F

* Well-Done: 160°F

Important Tip: Let your roast rest for 15-20 minutes after cooking. This allows the juices to redistribute, resulting in a more tender and flavorful roast.

For a 15 lb roast, I recommend using a slow cooker to ensure even cooking. This will take 8-10 hours on low. You can also use a combination of oven roasting and slow cooking, roasting the roast at 325°F for 1-2 hours and then finishing it in the slow cooker.

Enjoy your delicious bottom round roast!
