How Long Does It Take to Cook a Crown Roast?

Quick Answer

A crown roast takes 2–3.5 hours to cook, depending on whether you are preparing pork or lamb and the size of the roast. The general rule is 20 minutes per pound at 350°F (175°C), plus resting time. A typical 8–10 pound crown roast of pork needs about 2.5–3.5 hours in the oven.

Preparing a Crown Roast

What Is a Crown Roast?

A crown roast is formed by curving one or two racks of ribs into a circle with the bones pointing upward, resembling a crown. The center is often filled with stuffing. It is one of the most visually impressive roasts for holiday entertaining.

Preparation (15–20 Minutes)

Remove the roast from the refrigerator 30–60 minutes before cooking to allow it to come to room temperature, which promotes even cooking. Season generously with salt, pepper, garlic, and fresh herbs. For pork, a rub of sage, rosemary, and thyme is traditional. For lamb, use rosemary, garlic, and Dijon mustard.

Wrap the exposed bone tips in foil to prevent charring during roasting.

Cooking Methods

Standard Method (Recommended)

Roast at a consistent 350°F (175°C) for the entire cooking time. This produces even cooking and a tender result. Use a meat thermometer inserted into the thickest part of the meat, avoiding bone contact.

Reverse Sear Method

Start at 250°F (120°C) until the internal temperature reaches 10°F below target, then blast at 450°F (230°C) for 10–15 minutes to brown the exterior. This method takes slightly longer but produces a more evenly cooked roast with a beautiful crust.

High-Heat Start Method

Begin at 450°F (230°C) for 15–20 minutes to develop a golden crust, then reduce to 350°F (175°C) for the remainder. This is the most traditional approach for crown roasts.

Doneness Temperatures

Meat	Doneness	Remove at	After Resting
Pork	Safe minimum	140°F (60°C)	145°F (63°C)
Lamb	Medium-rare	130°F (54°C)	135°F (57°C)
Lamb	Medium	140°F (60°C)	145°F (63°C)
Lamb	Medium-well	150°F (66°C)	155°F (68°C)

Always remove the roast 5°F before your target temperature, as carryover cooking will bring it up during the rest.

Stuffing the Center

If filling the crown with stuffing, add it during the last 45–60 minutes of cooking. Pre-cook the stuffing before placing it in the center to ensure it reaches a safe 165°F (74°C). Popular fillings include wild rice pilaf, cornbread stuffing, and herbed bread stuffing.

Resting Is Essential

Allow the crown roast to rest for 15–20 minutes after removing from the oven. This redistributes juices throughout the meat, ensuring each slice is moist. Tent loosely with foil to retain warmth.

Key Takeaway

Plan for 2–3.5 hours of oven time for a crown roast, using 20 minutes per pound at 350°F as your baseline. A reliable meat thermometer is the best tool for ensuring perfect doneness regardless of variations in oven temperature and roast size.
