Frequently Asked Questions

What's the difference between ribeye roast and prime rib?
Prime rib is bone-in, while ribeye roast is boneless. Both come from the same primal cut (the rib section) and have similar flavor and marbling. Ribeye roast is easier to carve.
How long to cook a 5 lb ribeye roast?
A 5 lb ribeye roast at 325°F takes about 1 hour 10 minutes for medium-rare (130°F internal). Use a meat thermometer and remove 5°F below target temp.
Should I sear ribeye roast before or after roasting?
Both methods work. Searing before gives a head start on the crust. Reverse searing (roast first, sear last) gives more control over doneness. Many prefer reverse sear for better results.
