Ingredients

Scale

For the Rib Roast:

  • 1 bone-in rib roast (4 to 6 pounds)

  • 2 tbsp kosher salt

  • 1 tbsp black pepper

  • 1 tbsp garlic powder

  • 2 tsp dried thyme

  • 2 tsp dried rosemary

  • 2 tbsp olive oil or beef tallow

For the Chimichurri Sauce:

  • 1 cup fresh parsley (packed)

  • 1/4 cup fresh oregano (or 1 tbsp dried)

  • 4 garlic cloves

  • 2 tbsp red wine vinegar

  • 1/2 cup olive oil

  • 1/2 tsp red pepper flakes (optional)

  • Salt and black pepper to taste

  • Juice of 1/2 lemon (optional)

Instructions

  1. Let the roast sit at room temperature for 1–2 hours.

  2. Preheat oven to 250°F (120°C).

  3. Pat roast dry. Rub with olive oil or tallow.

  4. Mix salt, pepper, garlic powder, thyme, and rosemary. Rub all over the roast.

  5. Place roast bone-side down in a roasting pan with a rack.

  6. Insert meat thermometer into thickest part of the roast.

  7. Roast until internal temp reaches 120°F (rare), 125°F (medium rare), or 130°F (medium). This takes about 3–4 hours.

  8. Remove roast. Let rest 30–40 minutes.

  9. Turn oven up to 500°F (260°C).

  10. Return roast to oven for 10 minutes to crisp up the outside.

  11. Rest another 10 minutes before slicing.

For the Chimichurri:

  1. In a blender or food processor, add parsley, oregano, garlic, vinegar, salt, pepper, and red pepper flakes.

  2. Pulse until chopped.

  3. Slowly add olive oil while blending lightly.

  4. Taste and adjust salt or lemon if needed.

  5. Let it sit for 10–15 minutes before serving.

Notes

  • Always use a meat thermometer for best results.

  • Resting the roast twice is key for juicy meat.

  • Chimichurri can be made a day ahead and kept in the fridge.

  • Great with cauliflower mash, green beans, or grilled vegetables.
