Best Slow Cooked Prime Rib

I love prime rib. I look forward to making a delicious, juicy prime rib recipe every holiday season for my family! It's always a difficult choice which to choose from every year - they're all so delicious! - but my most popular recipe for prime rib is slow-cooked in the oven.

Cooking prime rib low and slow locks in all the juices for the best flavor and tenderness. You'll notice there's hardly any juice that drips from the roast when you perfectly cook it in the oven - that means all that juicy goodness stays in the beef!

This results in a prime rib roast that is more tender and juicy than any other method. After it's done roasting, I sear it for a beautiful, crisp brown crust.

I guarantee you're going to love this slow-cooked roast. It truly is the best prime rib recipe!
