Step-by-Step Beginner-Friendly Instructions

1. Prep the meat: Remove the beef roast from the refrigerator 1 hour before cooking to allow it to reach room temperature for even roasting.
2. Create the compound butter: In a small bowl, combine the softened butter, minced garlic, chopped rosemary, thyme, salt, and pepper. Mix until smooth.
3. Season the roast: Pat the beef completely dry with paper towels. Rub the garlic butter mixture generously all over the surface of the roast.
4. Start roasting: Preheat your oven to 450°F (230°C). Place the roast on a rack in a roasting pan, fat-side up.
5. Searing step: Roast at 450°F for 20 minutes to sear the outside. Then, reduce the heat to 325°F (165°C) and continue cooking for approximately 1.5 to 2 hours.
6. Check doneness: Use a meat thermometer to check the center of the thickest part. Aim for 125°F for medium-rare. ✨
7. Resting: Remove the roast from the oven, tent loosely with foil, and let it rest for at least 20-30 minutes before slicing. This locks in the juices!

💡 Pro Tips

• Always Rest: Never skip the resting phase; it is the secret to a succulent roast.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Substitution: If you cannot find a bone-in prime rib, a boneless beef ribeye roast works beautifully, though you may need to reduce the cooking time slightly.

Variations

• Citrus Kick: Add a tablespoon of fresh lemon zest to your butter mixture for a bright, aromatic twist.
• Extra Heat: Stir in a half-teaspoon of crushed red pepper flakes if you prefer a slight spicy kick.
