Epic Coffee Crusted Prime Rib Roast Recipe

Ingredients

• 3.63 kg (8 lb)bone-in prime rib roast
• 30 ml (2 tbsp)olive oil
• 120 ml (1/2 cup)coffee rub
• 1 medium, thickly slicedonion
• to tastewhole garlic cloves
• to tastewhole mini sweet peppers

Instructions

1. 1

   Prepare the roast

   Ask your butcher to remove the chine bone and trim the fat to 6 mm (1/4 inch) to save time and effort.

2. 2

   Bring to room temperature

   Let the meat stand at room temperature for up to 3 hours before cooking.

3. 3

   Apply the rub

   Either the night before or 2 hours before cooking, coat the whole roast with olive oil and a generous amount of coffee rub. Use more or less depending on the size of your roast.

4. 4

   Heat the oven

   Preheat the oven to 220°C (425°F).

5. 5

   Sear the meat

   Heat a skillet with olive oil and sear the roast on all sides for 1–2 minutes per side, including the ends.

6. 6

   Set up the pan

   Arrange the thick onion slices on the bottom of a roasting pan. Set the roast on top, with the rib bones down and the fat side up.

7. 7

   Position the rack

   Adjust the oven racks so the roasting pan will sit in the bottom third of the oven.

8. 8

   Roast the meat

   Roast for 20 minutes, then reduce the oven to 175°C (350°F) and roast for 2 hours, or until it reaches your desired temperature.

9. 9

   Add the vegetables

   One hour into cooking, place the whole garlic cloves and mini sweet peppers around the roast.

10. 10

    Check the temperature

    Use a digital thermometer. For medium-rare, it should read 43–49°C (110–120°F); the meat will continue cooking after it comes out of the oven.

11. 11

    Rest the roast

    Transfer the roast to a carving board and let it rest for at least 30 minutes before slicing.

12. 12

    Remove the twine

    Remove the twine before slicing.

13. 13

    Serve

    Serve immediately.

What is coffee-crusted prime rib?

Prime rib is a large rib roast, traditionally served as a centrepiece in American cooking. This version uses a coffee-based seasoning to give the outside a dark, aromatic crust.

Coffee rub: Ground coffee or espresso is often paired with pepper, brown sugar and spices in this style of rub. The roast’s high-heat start and long, gentler cook help build a browned exterior while keeping the centre tender.

Nutrition and macros by portion

The nutrition label shows one serving as written: 1050 calories, 84g protein, 4g carbs, 78g fat.

Most of the protein and fat come from the prime rib, while the coffee rub may contribute some carbohydrate depending on its ingredients, including any brown sugar. The garlic, onion and peppers add relatively small amounts per serving; balance the plate with vegetables or salad, and add potatoes or bread if you want a more substantial meal.

Choosing and preparing the roast

Butcher’s trim: Having the chine bone removed and the fat trimmed to about 6 mm makes the roast easier to handle and carve. Ask the butcher to keep the rib bones attached beneath the meat.

Room temperature: The method allows up to 3 hours out of the fridge before cooking. Keep to that stated limit, and avoid leaving the roast somewhere warm.

Building the coffee crust

Seasoning time: The rub can go on the night before or 2 hours before roasting, giving you flexibility around the meal. Coat the roast evenly so the seasoning reaches the sides as well as the top.

Rub quantity: The recipe gives 120 ml (1/2 cup) as a guide and notes that the amount may vary with the roast’s size. Use enough to cover the surface generously without leaving large bare patches.

Why sear before roasting?

Hot pan: Searing for 1–2 minutes on each side, including the ends, browns the outside before the roast goes into the oven. Use a pan large enough to turn the meat safely.

Onion base: Thick onion slices sit beneath the roast in the roasting pan. They provide a bed for the meat while the bones face down and the fat faces up, as directed.

Getting the doneness right

Thermometer check: Insert a digital thermometer into the thickest part of the meat, avoiding bone. The recipe’s stated medium-rare target is 43–49°C (110–120°F) before resting.

Carry-over cooking: The roast continues to cook after it leaves the oven, so the final doneness will be higher than the reading taken in the oven. Begin checking before the end of the cooking period if you are aiming for a particular result.

Timing and resting

Two-stage roast: The method starts at 220°C for 20 minutes, then lowers the oven to 175°C for 2 hours or until the desired temperature is reached. Actual timing can vary with the roast and oven, so use temperature rather than time alone to judge doneness.

Resting time: Leave the roast on a carving board for at least 30 minutes before slicing. This pause is part of the recipe, so allow for it when planning when to serve.

Serving the roast

Roasted vegetables: The garlic cloves and mini sweet peppers go into the pan one hour after roasting begins, so they cook alongside the beef. Serve them with the sliced roast and the softened onions.

A fresh side: Pair the rich meat with a crisp green salad or simply cooked vegetables. Potatoes or bread can make the meal more filling.

Recipe notes & tips

• Ask the butcher to remove the chine bone and trim the fat before you bring the roast home.
• Apply the rub evenly, including the sides and ends of the roast.
• Use a digital thermometer and check the thickest part without touching bone.
• Set the roasting pan in the bottom third of the oven as directed.
• Rest the roast for at least 30 minutes before carving.
• Remove all the twine before slicing and serving.

Variations

• Extra pepper: Add more freshly ground black pepper to the coffee rub for a sharper crust.
• Herb finish: Serve with chopped fresh herbs for a bright contrast to the roast.
• More vegetables: Add extra onions or mini sweet peppers around the roast.
• Garlic flavour: Serve the cooked garlic cloves alongside the sliced beef.
• Different doneness: Use the thermometer to cook the roast to your preferred level, checking it carefully as it approaches the target.

Common mistakes to avoid

• Skipping the sear: The exterior misses the browning step; sear every side, including the ends, for 1–2 minutes.
• Guessing doneness: Roasting time alone can mislead; use a digital thermometer in the thickest part of the meat.
• Cutting too soon: Slicing immediately loses the required resting time; wait at least 30 minutes before carving.
• Leaving on the twine: It gets in the way of carving; remove it before slicing.
• Ignoring the bones: A thermometer touching bone can give an unhelpful reading; position it in the meat instead.
• Forgetting the vegetables: Adding garlic and peppers at the start changes their cooking time; add them one hour into roasting.

How to store

Refrigerate leftover beef and vegetables in a covered container within 2 hours of serving and eat within 3–4 days. Reheat portions until piping hot, or serve the beef cold in sandwiches; gentle reheating helps avoid drying it out.
