Prime Rib Roast — A Keto Holiday Showstopper
Few dishes command a table like a perfectly cooked Prime Rib Roast. This keto version keeps all the indulgence — buttery, tender beef with a crisp herb crust — but stays low in carbs and rich in flavor. Garlic, rosemary, and thyme blend beautifully into the buttery rub, creating a roast that’s both elegant and effortless. Whether it’s for Christmas dinner, a family gathering, or a Sunday feast, this roast guarantees you’ll impress without stress.
A Roast Worth Celebrating
I still remember my first time cooking prime rib — that moment of slicing into the roast and seeing the rosy center surrounded by a crust so aromatic it filled the house. It’s the kind of dish that feels like a celebration in itself. Over time, I learned that great prime rib isn’t about complicated steps — it’s about quality ingredients, a good sear, and patience while it rests. Once you’ve done it right, it becomes your signature holiday centerpiece.
The Secret to Perfect Prime Rib
- Room Temperature Start: Letting the roast warm before cooking ensures even doneness.
- High-Heat Sear: That first blast at 450°F locks in flavor and creates a crisp crust.
- Gentle Finish: Lower heat keeps the inside tender and juicy.
- Resting Time: It’s not optional — it’s when the magic happens and the juices settle.
Pro Tip from the Kitchen
Salt your roast the day before. This simple dry brine draws moisture to the surface, helping you achieve that restaurant-quality crust while enhancing every bite with deeper flavor.
Perfect Keto Pairings
Round out your plate with:
- Creamy cauliflower mash for a buttery, potato-free side.
- Garlic butter green beans for freshness and crunch.
- Keto horseradish cream sauce to add that bold, classic contrast.

Prime Rib Roast
Equipment
- Roasting Pan
- Meat Thermometer
- Basting Brush
- Oven
Ingredients
Main Ingredients
- 5 lb prime rib roast bone-in or boneless
- 1/3 cup butter softened
- 4 cloves garlic minced
- 1 tbsp fresh rosemary finely chopped
- 1 tbsp fresh thyme finely chopped
- 1 tbsp olive oil
- 2 tsp kosher salt
- 1 tsp black pepper freshly ground
Instructions
- Remove the prime rib from the refrigerator at least 1 hour before cooking to bring it to room temperature. Preheat oven to 450°F (230°C).
- In a small bowl, combine softened butter, olive oil, garlic, rosemary, thyme, salt, and black pepper to form a paste.
- Pat the roast dry with paper towels. Rub the butter mixture all over the meat, ensuring an even coating on all sides.
- Place the roast bone-side down in a roasting pan fitted with a rack. Insert a meat thermometer into the thickest part of the roast, avoiding bone.
- Roast at 450°F (230°C) for 20 minutes to sear, then reduce heat to 325°F (165°C) and continue roasting for about 1 hour 30 minutes, or until the thermometer reads 125°F (52°C) for medium-rare or 135°F (57°C) for medium.
- Remove from oven and tent loosely with foil. Let rest for 20 minutes before slicing to allow juices to redistribute.
- Slice thickly against the grain and serve warm with pan drippings or keto horseradish cream sauce.
