DON’T BE INTIMIDATED BY THIS DELICIOUS MEAT
Prime rib has always intimidated me, even as a food blogger. This traditional holiday staple always wigged me out, because I convinced myself I would overcook it and or under cook it. On Christmas, I decided it was time to let these silly thoughts go and make Prime Rib.
I’ve created this easy and perfect prime rib recipe just for you! The ones who are intimidated when cooking huge chunks of meat. Be intimidated no more because my Prime Rib recipe is easy and I’ve listed the steps below.

USE THE RIGHT TOOLS
The most important item you need for this Prime Rib recipe, besides the meat, is a good meat thermometer. You can pick one up at your local grocery store or from Amazon.
Make sure it’s a quality brand because the meat thermometer is an integral part of creating a perfectly cooked prime rib. You will also need a good roasting pan with a roasting pan rack.
This ensures even cooking and tender meat. The prime rib should be pink in the middle. Some people prefer it really raw, but I don’t. I like mine to be a good pink hue, but not bloody. If red juice coming out of your Prime Rib is your jam, simply cook the prime rib for less time per pound.

SPICES AND LOADS OF BUTTER ARE YOUR FRIENDS
You can find a good, quality prime rib seasoning from your local butcher or grocery store. I purchased a store-bought that’s made with no nasty chemicals.
The key to a quality prime rib seasoning is low salt. The only ingredients you want in your prime rib rub are sea-salt, paprika, oregano, celery, garlic, onion, pepper, rosemary, and parsley. That’s it!
If you are unable to find a good prime rib rub with these seasonings, simply make one yourself. It’s easy and you can use it for roasting other meats as well.

Butter, butter, butter. You know when you go to a steak house and the steak you order is tender and full of flavor? You achieve this by basking your prime rib in butter. Loads of butter. And not just any butter, but you want to use a high-quality Irish Butter.
If you follow me on Instagram, then you know the only type of butter we use in our household is Kerry Gold Irish Butter. It’s a rich gold color, and it makes it so much more flavorful. Not sponsored at all, I just love this stuff for cooking.

LET’S MAKE THE PERFECT PRIME RIB
Preheat your oven to 450-degrees. The first step is you take your prime rib, pat it dry, and rub room temperature butter all over it. Next, rub your spices all over the buttered prime rib. Place the prime rib in a roasting pan and let it sit room temperature before you cook it. Add some fresh rosemary sprigs to the bottom of the roasting pan.


Place the prime rib in the oven and roast it for 30-minutes at 450-degrees. Then, roast it at 350-degrees for an hour to an hour and a half. The sweet spot to making perfect prime rib is to roast it in total for an hour and thirty minutes.
You don’t want to overcook the meat, but you don’t want to undercook it either. Insert a meat thermometer into the prime rib and make sure it reaches an internal temperature of 120-degrees for medium.
If you like it more on the rare side, 110-degrees is rare, and medium well would be 130-degrees. We found that 120-degrees was perfect!

Let the prime rib sit under tinfoil for 5-minutes and then slice into it. That’s it! This is how you make perfect prime rib.
Not nearly as intimidating as you thought, and you’ll impress all of your family and friends with this easy holiday staple.
Pair it with fresh horseradish sauce and you’ve got a delicious meal right at your fingertips!
