Prime rib is one of the most popular special-occasion beef dishes in America. Although it looks like something you’d order at an expensive steakhouse, you can prepare a delicious version at home with a few simple ingredients and the right cooking technique.
The secret is choosing a good-quality beef roast, seasoning it properly, and using a meat thermometer to avoid overcooking.
What Is Prime Rib?
Prime rib is a beef roast cut from the rib section of the animal. It is known for its rich flavor, tender texture, and beautiful marbling.
Despite the name, prime rib does not always mean USDA Prime grade beef. The word can refer to the cut itself, while USDA Prime is a separate quality grade.
Prime rib is often served during holidays, celebrations, and special family dinners.

How to Make Garlic Herb Prime Rib Roast
Step 1: Prepare the Beef
Remove the beef roast from the refrigerator and pat it dry with paper towels.
Let it sit while you prepare the seasoning. Avoid leaving raw meat at room temperature for an extended period.
Preheat your oven to 450°F (232°C).
Step 2: Make the Garlic Herb Seasoning
In a small bowl, combine the olive oil or softened butter, minced garlic, rosemary, thyme, salt, black pepper, and onion powder.
Mix until a thick herb paste forms.
Step 3: Season the Roast
Rub the garlic herb mixture evenly over the entire surface of the beef.
Place the roast fat-side up in a roasting pan fitted with a rack.
Step 4: Start Roasting
Roast the beef at 450°F (232°C) for 15 minutes to help develop a flavorful outer crust.
Reduce the oven temperature to 325°F (163°C) and continue roasting.
Cooking time varies depending on the size, shape, and starting temperature of the roast. Use a reliable meat thermometer rather than relying only on the clock.
Step 5: Check the Internal Temperature
Insert the thermometer into the thickest part of the meat, avoiding the bone and large pockets of fat.
For food safety, the USDA recommends that beef roasts reach an internal temperature of 145°F (63°C), followed by a rest of at least 3 minutes.
If you prefer a pinker center, understand that lower cooking temperatures do not meet that USDA whole-cut beef recommendation.
Step 6: Rest Before Slicing
Remove the roast from the oven and transfer it to a cutting board.
Loosely cover it with foil and allow it to rest for at least 15–20 minutes before carving.
Resting helps the juices settle and makes slicing easier.
Step 7: Prepare the Asparagus
While the beef rests, toss the asparagus with olive oil, salt, and black pepper.
Roast at 400°F (204°C) for approximately 10–15 minutes, depending on thickness, until tender.
Step 8: Prepare the Loaded Baked Potatoes
Bake the potatoes at 400°F (204°C) until tender when pierced with a fork, usually around 45–60 minutes depending on their size.
Cut each potato open and gently fluff the inside with a fork.
Add butter, sour cream, shredded cheddar, bacon bits, and chopped chives.
Step 9: Slice and Serve
Slice the rested prime rib against the grain.
Arrange the beef on a serving platter with roasted asparagus and loaded baked potatoes.
Serve immediately while everything is warm.
What Is the Best Temperature for Cooking Prime Rib?
A meat thermometer is one of the most useful tools when preparing a beef rib roast.
The USDA’s recommended minimum internal temperature for beef roasts is 145°F (63°C), followed by a rest of at least 3 minutes.
Remember that oven temperature and internal meat temperature are two different things. Always measure the temperature inside the thickest part of the roast.
How Much Prime Rib Should You Buy Per Person?
A practical estimate for planning a dinner is:
- Bone-in roast: approximately 1 pound per person.
- Boneless roast: approximately 3/4 pound per person.
The amount you need depends on appetites, side dishes, and whether you want leftovers.
How Much Does Prime Rib Cost?
Prime rib prices vary depending on the beef grade, location, butcher, season, and whether you choose bone-in or boneless.
USDA Prime beef generally costs more than Choice or Select grades.
For the best value, compare prices at local grocery stores and butcher shops. Ask whether the roast is USDA Prime, Choice, or another grade before purchasing.
Tips for the Best Homemade Prime Rib
- Use a meat thermometer: This is the best way to monitor doneness.
- Season generously: A large roast needs enough seasoning to flavor the outer surface.
- Dry the surface: Patting the meat dry helps the seasoning stick and encourages browning.
- Avoid cutting immediately: Resting makes carving easier.
- Slice against the grain: This helps make each serving more tender.
- Save the pan drippings: They can be used to prepare a flavorful beef gravy or au jus.
What to Serve With Prime Rib
Prime rib pairs beautifully with many classic side dishes:
- Loaded baked potatoes
- Roasted asparagus
- Garlic mashed potatoes
- Creamed spinach
- Roasted carrots
- Yorkshire pudding
- Fresh garden salad
- Homemade beef gravy or au jus
How to Store and Reheat Leftover Prime Rib
Allow leftovers to cool and refrigerate them promptly in shallow, airtight containers.
Store cooked beef in the refrigerator for 3–4 days.
For longer storage, freeze leftovers in airtight, freezer-safe packaging.
To reheat, place slices in an oven-safe dish with a little beef broth. Cover with foil and warm gently until heated through. Avoid excessive heat because it can dry out the meat.
Frequently Asked Questions
Is prime rib the same as ribeye?
They come from the same general rib section of the cow, but they are usually sold differently. Prime rib is generally a roast, while ribeye is commonly cut into individual steaks.
Is prime rib always USDA Prime beef?
No. Prime rib describes a cut of beef, not necessarily its USDA quality grade. A prime rib roast may be graded Prime, Choice, or another grade.
Why is prime rib pink inside?
The pink color is related to the cooking temperature and the way the meat is prepared. Color alone cannot confirm whether beef is safely cooked, so use a meat thermometer.
Should prime rib be cooked covered or uncovered?
It is commonly roasted uncovered so the outside can brown. If the surface becomes too dark, you can loosely cover it with foil.
Can I prepare prime rib the day before?
You can prepare the seasoning mixture ahead of time and refrigerate it. For the best texture, roast the beef close to serving time. Leftovers can be refrigerated and reheated carefully.
