The day before you plan to serve the prime rib, remove roast from the package and dry thoroughly with paper towels. Set roast on a baking sheet, and place in refrigerator overnight. Remove from refrigerator 1 hour before cooking to allow beef to reach room temperature.

Rub the roast all over with horseradish and Dijon mustard. Mix kosher salt, black pepper, thyme, and garlic powder together in small bowl; sprinkle over the roast.

Preheat the oven to 450 degrees F (230 degrees C). Place celery, carrot, and onion into the bottom of a roasting pan; place the roast on top.

Roast in the preheated oven for 30 minutes. Reduce oven temperature to 350 degrees F (175 degrees C), and roast until the meat is browned and an instant-read meat thermometer inserted into the thickest part of the roast reads 130 degrees F (54 degrees C) for medium-rare.

Remove from oven, transfer roast to a platter, and cover with a tent of aluminum foil. Allow to rest for 30 minutes. The temperature of the meat will rise about 10 degrees during resting time.

To make au jus sauce: Skim excess fat from pan drippings in the roasting pan. Place the pan over a burner set to medium heat; stir in beef base and 1 1/2 cups of water. Bring to a boil, scraping and dissolving any brown flavor bits from the bottom of the pan.

Strain out and discard vegetables. Combine cornstarch and 1 teaspoon of water in a small bowl; whisk the mixture into sauce.

Allow sauce to thicken slightly; pour into a gravy boat and serve with roast.

Over the Fire Scalloped Potatoes
I make these great hands-on potatoes beforehand when everything is going to be cooked on the grill. They're also great for a campfire on a small grill. These scalloped potatoes will keep everyone coming back for more. Have the recipe in hand!

This is Alexis Olivia's best recipe ever! A true Italian sharing a delicious pasta carbonara dish with chicken that everyone will love. Yes, a bit fattening, yet worth it if you are able to indulge every once in a while! Enjoy!
Duck Fat Steak Fries
You know a potato side dish is going to be good when 75% of the name refers to fat or meat. These super-crusty, oven-fried potato wedges, or 'steak fries' as they call them where I'm from, are done with rendered duck fat, and while I'm a big fan of ones done with olive oil and/or butter, these really are better.
