Step-by-step instructions
- Begin by allowing your bone-in prime rib roast to come to room temperature for roughly 1 hour. Pat it dry to promote a nice crust when cooking.
- Generously rub the roast with olive oil or softened butter, minced garlic, salt, pepper, and your chopped fresh herbs. Don’t be shy—this is where a lot of the flavor comes from!
- Preheat your oven to 450°F (230°C). Place the roast in the oven for 15 minutes for a good sear.
- After 15 minutes, reduce the oven temperature to 325°F (165°C) and continue roasting for 1½ – 2 hours. Use a meat thermometer to ensure you reach an internal temperature of 130°F (54°C) for that perfect medium-rare.
- Once done, let the roast rest for at least 20 minutes to allow the juices to redistribute.
- Slice and serve with your choice of au jus or horseradish sauce for an extra flavor kick.
Best ways to enjoy it
When it comes to serving the BEST Prime Rib Roast, the options are endless. Serve it thinly sliced on a platter, garnished with fresh herbs for a beautiful presentation. Pair it with classic sides like creamy mashed potatoes or roasted vegetables, or go for something a bit different—try a tangy Brussels sprouts salad for a delightful contrast. Don’t forget to offer horseradish sauce, which adds a nice kick that complements the rich beef beautifully.
Storage and reheating tips
To keep leftover prime rib fresh, wrap it tightly in plastic wrap or foil and store it in the refrigerator. It should last about 3-4 days. For longer preservation, you can freeze slices wrapped in airtight containers or freezer bags—just remember to label them. When reheating, aim for low and slow methods, like in the oven, to prevent drying it out.
Helpful cooking tips
- For the best sear, ensure your roast is pat dry. Moisture can inhibit that beautiful crust you’re aiming for.
- Use a meat thermometer for precision—no more guessing! It’s the best way to ensure you get the perfect doneness.
- If you prefer a herb crust, consider adding additional herbs to the rub (like parsley or tarragon) for more complexity.
Creative twists
If you’re feeling adventurous, there are plenty of ways to switch it up. Try experimenting with different flavors by adding mustard to your herb rub or using smoked salt for an extra layer of taste. You can also serve with a variety of sauces, like a port wine reduction or a garlic and herb chimichurri. For a fun twist, think about making prime rib sandwiches with the leftovers, adding toppings like sautéed mushrooms or blue cheese.
