This comprehensive guide will walk you through everything you need to know about sous viding prime rib, including time, temperature, and the best practices to achieve a perfectly tender and juicy roast every time.
What Is Sous Vide Cooking?
Sous vide, which means “under vacuum” in French, is a method of cooking in which food is sealed in a vacuum-sealed bag and cooked in a water bath at a precise temperature. This ensures that the food is cooked evenly and remains juicy and flavorful. Sous vide offers an excellent method for achieving consistent doneness throughout a prime rib roast.
To learn more about the fundamentals of sous vide cooking, we recommend this comprehensive guide from Serious Eats, which provides a thorough explanation of the technique and its advantages.
Why Sous Vide a Prime Rib Roast?
The consistent results achieved with sous vide make it a preferred method for preparing prime rib among both chefs and home cooks. Traditional oven roasting can result in uneven cooking, with edges being overdone while the center is just right. With sous vide, the entire roast is cooked to the exact level of doneness you prefer. This ensures a perfect bite every time, with no guesswork involved.
In addition to the consistent cooking, sous vide also preserves the flavor and tenderness of the meat. According to a study by the National Library of Medicine, sous vide cooking preserves moisture content significantly better compared to traditional methods.
How Long Does It Take to Sous Vide a Prime Rib Roast?
The cooking time for sous vide prime rib roast varies depending on the thickness of the meat and the level of doneness desired. Below is a detailed breakdown:
Factors That Affect Cooking Time
- Thickness of the Roast: The thickness of the roast will affect the cooking time. Typically, a 2-3 inch thick prime rib will take about 6 to 8 hours.
- Desired Doneness: The target doneness will also impact the time. The standard temperature and time for various levels of doneness are:
- Rare (125°F / 52°C): 6-8 hours
- Medium-Rare (130°F / 54°C): 8-10 hours
- Medium (135°F / 57°C): 8-10 hours
- Medium-Well (145°F / 63°C): 8-12 hours
- Weight: The weight of the roast can also influence cooking time. Generally, a larger roast will require slightly more time to reach the desired internal temperature.
Step-by-Step Guide to Sous Vide Prime Rib Roast
- Season the Roast: Before sous viding, generously season your prime rib with salt, pepper, garlic, and herbs. You can also add butter to enhance the flavor.
- Vacuum Seal: Place the seasoned roast in a vacuum-sealed bag. If you don’t have a vacuum sealer, you can use the water displacement method with a resealable bag.
- Set the Sous Vide: Fill a container with water and set your sous vide device to the desired temperature (e.g., 130°F for medium-rare).
- Cook: Submerge the bag in the water bath and cook for the recommended time (usually 8-10 hours).
- Finish the Roast: Once cooked, remove the roast from the bag, pat it dry, and sear it in a hot skillet for 1-2 minutes per side to create a crust.
Temperature and Time Chart for Prime Rib Roast
| Doneness Level | Temperature (°F) | Cooking Time (Hours) |
|---|---|---|
| Rare | 125 | 6-8 |
| Medium-Rare | 130 | 8-10 |

Why Cooking Time Matters in Sous Vide
One of the most common questions is, how long does it take to sous vide a prime rib roast? The answer depends largely on the cut, size, and the texture you’re aiming for. Cooking times are more forgiving in sous vide since the water bath maintains an even temperature, allowing the meat to cook gradually without overcooking.
If you have a larger cut, for example, a 5-6 lb roast, you should expect to cook it for about 10 hours. The advantage of sous vide is that you can leave it in the water bath longer without the risk of overcooking.
Sous vide cooking times are also flexible depending on personal preferences. If you prefer your prime rib roast to be extra tender, you can cook it for up to 12 hours. However, if you like it to have a bit more texture, you may opt for a shorter cook time, such as 6 hours.
How to Choose the Right Prime Rib Roast for Sous Vide
Choosing the right cut of prime rib is an important factor in achieving the perfect sous vide roast. Here are a few things to consider:
- Bone-In vs. Boneless: Bone-in roasts tend to have more flavor since the bone helps distribute heat more evenly. Boneless roasts, however, are easier to handle and slice.
- Marbling: Look for a prime rib with good marbling (intramuscular fat) for a juicy and flavorful roast. Higher quality cuts, such as USDA Prime, will generally have more marbling.
- Size: The size of the roast matters for sous vide cooking. Larger roasts will require more time, so ensure you have a sous vide container that is large enough to accommodate the roast.
Prepping the Prime Rib for Sous Vide
Seasoning
Seasoning is crucial for enhancing the flavor of your prime rib roast. Here’s how you can do it:
- Dry Brine: Apply salt evenly to all sides of the roast and let it rest in the refrigerator for at least 24 hours. This helps tenderize the meat and enhances the flavor. To make the most of dry brining, you should absolutely check out our recipe for perfect sous vide prime rib roast. This helps tenderize the meat and enhances the flavor.
- Herbs and Spices: After dry brining, rub the roast with herbs like rosemary and thyme, along with freshly ground black pepper and garlic. Adding a little olive oil can help the herbs adhere better.
- Butter: Adding a few pats of butter to the bag before sealing can add extra richness to the final dish.
Vacuum Sealing and Bagging Tips
When sous viding, it is crucial to properly seal the roast to ensure that no water enters the bag and that the flavor stays locked in.
- Vacuum Sealer: Use a vacuum sealer to remove air from the bag completely. This will help the meat cook evenly and prevent any unwanted moisture from entering.
- Water Displacement Method: If you don’t have a vacuum sealer, use a high-quality freezer bag. Place the roast in the bag, and slowly lower it into a container of water. The pressure of the water will push out the air, and you can then seal the bag tightly.
- Double Bagging: For extra security, consider double-bagging the roast. This is especially helpful if you’re cooking for an extended period.
Step-by-Step Cooking Process
1. Setting Up the Sous Vide Bath
Fill a large container or pot with water. Attach your sous vide immersion circulator and set it to your desired temperature based on the doneness chart provided earlier.
2. Cooking the Prime Rib
Once the water reaches the correct temperature, lower the vacuum-sealed bag into the water. Ensure that the entire roast is submerged, and use clips to attach the bag to the side of the container if necessary.
- Maintaining Water Level: Make sure the water level stays consistent throughout the cooking process. Covering the container with plastic wrap or a lid can help minimize evaporation.
3. Monitoring the Cook
Sous vide cooking is hands-off, but it’s good practice to occasionally check the water level and ensure the bag is fully submerged. You can also use a sous vide weight to keep the bag from floating. You can also check out our recipes like pumpkin banana loaf while you wait!
Finishing the Prime Rib Roast
Resting the Meat
After the cooking time is complete, carefully remove the bag from the water bath. Let the roast rest inside the bag for 10 minutes. This allows the juices to redistribute evenly throughout the meat.
Searing for Maximum Flavor
- Pat Dry: Remove the roast from the bag and pat it completely dry with paper towels. Removing excess moisture ensures a better sear.
- High-Heat Sear: Heat a cast-iron skillet over high heat and add a small amount of high smoke point oil (such as avocado oil). Sear each side of the roast for 1-2 minutes until a deep, golden-brown crust forms.
- Optional Finishes: For added flavor, you can baste the roast with butter, garlic, and herbs during the searing process.
Serving Suggestions for Sous Vide Prime Rib Roast
Carving the Roast
- Bone Removal: If you used a bone-in roast, consider removing the bones before carving. The bones can be served separately or saved for making stock.
- Slicing: Use a sharp carving knife to cut the roast into slices that are about 1/2 inch thick. This thickness provides the best balance of tenderness and flavor.
Side Dishes
Prime rib roast pairs well with a variety of sides, such as:
- Garlic Mashed Potatoes: Creamy mashed potatoes with garlic and butter make an excellent accompaniment.
- Roasted Vegetables: Carrots, Brussels sprouts, and parsnips roasted with olive oil and herbs complement the rich flavor of the roast.
- Yorkshire Pudding: A classic side for prime rib, Yorkshire pudding is perfect for soaking up the flavorful juices.
Sauces
- Au Jus: Use the juices from the sous vide bag to create a flavorful au jus.
- Horseradish Cream: A tangy horseradish sauce is a classic pairing that cuts through the richness of the meat. If you want to top your roast with something sweet, then you should definitely try our earl grey cookies recipe!
