Let’s begin!

  • Prep Time: 40 minutes
  • Cook Time: 90 minutes
  • Total Time: 2 hours 10 minutes
  • Yield: 6 servings 1x

Ingredients

Units Scale

For the prime rib:

  • 1 (4-5 pound) boneless prime rib roast
  • 2 tablespoons olive oil
  • 2 tablespoons kosher salt
  • 1 tablespoon black pepper
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon dried thyme
  • 1 tablespoon dried rosemary

For the garlic mash:

  • 3 pounds Yukon Gold potatoes, peeled and quartered
  • 4 cloves garlic, minced
  • 1 cup heavy cream
  • 1/2 cup unsalted butter
  • Salt and pepper to taste

Instructions

  1. Prepare the Prime Rib (10 minutes):
    Let the prime rib sit at room temperature for about 1 hour before cooking. Preheat your oven to 450°F (232°C). Rub the prime rib all over with olive oil. Mix salt, pepper, garlic powder, onion powder, thyme, and rosemary together in a bowl and rub this mixture evenly over the meat.
  2. Roast the Prime Rib (Approx. 90 minutes):
    Place the seasoned prime rib in a roasting pan or another oven-safe pan, fat side up. Roast in the preheated oven for 20 minutes, then reduce the oven temperature to 325°F (163°C). Continue roasting until the desired doneness is reached, about 15 minutes per pound for medium-rare. Use a meat thermometer to check for doneness: 135°F (57°C) for medium-rare.
  3. Rest the Meat (20 minutes):
    Once cooked to your liking, remove the prime rib from the oven. Cover it loosely with foil and let it rest for at least 20 minutes before slicing. This allows the juices to redistribute throughout the meat, ensuring it’s moist and flavorful.
  4. Prepare the Garlic Mashed Potatoes (30 minutes):
    While the prime rib is resting, boil the potatoes in a large pot of salted water until tender, about 20 minutes. In a small saucepan, melt the butter with the garlic and then add the cream, heating until just warm. Drain the potatoes and return them to the pot. Mash the potatoes, adding the garlic-butter-cream mixture gradually until the potatoes are smooth and creamy. Season with salt and pepper to taste.
  5. Serve:
    Slice the rested prime rib and serve alongside the garlic mashed potatoes. You can garnish the potatoes with a bit of chopped parsley or chives for added color and flavor.

Pair this with...

Roasted Asparagus with Sea Salt

Start by preheating your oven. Take fresh asparagus spears, snap off the tough ends, and lay them out on a baking sheet. A little drizzle of olive oil goes a long way in giving them a lovely coat. Now, for the pièce de résistance, sprinkle some coarse sea salt over the top. It not only elevates the flavor but also gives a delightful crunch. Pop them in the oven and roast until they're tender yet crisp, with hints of golden brown at the tips. The result? A dish that's vibrant in color, rich in flavor, and just a touch fancy.

Honey Glazed Carrots

Begin by cleaning and peeling your carrots. If they're large, you might want to slice them into smaller, uniform pieces for even cooking. In a pan, bring a bit of water to a simmer and add the carrots, letting them steam until they're tender but still have a bite. Drain any excess water, then return the pan to the heat. Add a good dollop of butter and let it melt, followed by a generous drizzle of honey. Toss the carrots in this buttery, sweet mixture, seasoning with a pinch of salt and maybe a sprinkle of fresh thyme or parsley for an herbal touch. Let them cook a bit longer until they're beautifully glazed and glistening.

Easy Dinner Rolls

Start by combining warm water, yeast, and a bit of sugar in a bowl, letting it sit until it's frothy. In a larger bowl, mix together softened butter, salt, the rest of your sugar, and some milk. Slowly add in flour, mixing until you have a soft dough. Knead this dough on a floured surface until smooth. Place it in a greased bowl, cover, and let it rise until doubled in size. Once risen, divide the dough into small balls and arrange them on a baking tray. Let them rise again briefly. Bake in a preheated oven until golden brown. Brush with melted butter right out of the oven for a glossy finish.
