How long does it take to cook a 15 lb beef roast at 250 degrees in barbecue pit?

It's impossible to give you an exact time for cooking a 15 lb beef roast at 250 degrees in a barbecue pit. Here's why:

* Meat Type and Cut: The specific cut of beef will heavily influence cooking time. A chuck roast will take longer than a ribeye roast.

* Internal Temperature: You want your beef roast to reach a safe internal temperature for consumption, typically 145°F for medium-rare.

* Pit Type and Size: Different barbecue pits have different heat distribution and insulation levels.

* Fat Content: Fattier cuts of beef will take longer to cook through.

* Desired Doneness: How well-done you prefer your roast will also determine cooking time.

Here's a general guide, but it's crucial to use a meat thermometer:

* Estimate: A 15 lb beef roast will likely take 4-6 hours at 250°F.

* Internal Temperature: Aim for an internal temperature of 145°F for medium-rare.

* Resting Time: Let the roast rest for at least 15-20 minutes after cooking to allow juices to redistribute.

Recommendations:

1. Use a Thermometer: The most reliable way to determine doneness is with a meat thermometer. Insert it into the thickest part of the roast, making sure not to touch bone.

2. Check Frequently: Start checking the internal temperature after 3 hours and check every 30-45 minutes.

3. Adjust Cooking Time: If the roast is cooking too quickly, lower the pit temperature slightly. If it's taking too long, raise the temperature slightly.

Remember: Cooking times are just estimates. Always use a meat thermometer for accurate results.
