Ingredients for instant pot prime rib roast
Six ingredients transform your Instant Pot into a restaurant-quality prime rib showstopper.
| Ingredient | Amount | Notes |
|---|---|---|
| Prime Rib Roast 🥩 | 4 lb | Bone-in, 1.5-2 inches thick |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Coarse grind for texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for searing |
| Garlic Cloves 🧄 | 8 cloves | Smashed for infusion |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Beef Au Jus 🍲 | 2 cups | Store-bought or homemade |
| Horseradish Cream 🧀 | ½ cup | Classic pairing option |
| Red Wine 🍷 | ½ cup | Bold dry red preferred |
| Beef Tallow or Olive Oil 🫒 | 2 tbsp | For Instant Pot sear |
| Meat Tenderizer 🔪 | 1 tbsp | Powdered, optional |
The prime rib is non-negotiable—look for bone-in cuts at your butcher or Costco for the best marbling. Thickness matters too: 1.5-2 inches ensures even cooking. I always ask for the rib to be trimmed of excess fat—just enough to keep it juicy without grease. For fresh herbs, Whole Foods or local farmers markets have the most vibrant rosemary and thyme. The red wine should be bold—Cabernet Sauvignon or Merlot work best, whatever’s open in your fridge.
No red wine? Beef broth with a splash of balsamic does the trick. Short on fresh herbs? Dried thyme at one-third the amount works, but rosemary’s flavor is harder to replicate. The au jus can be store-bought (Kraft or French’s are fine), but homemade (simmer beef bones with veggies) tastes exponentially better. For the sear, beef tallow adds richness, but olive oil works perfectly if that’s what you’ve got. The meat tenderizer is optional—skip it if your roast is already tender.
Prime rib reheats beautifully—2-3 minutes on low in the Instant Pot keeps it moist. Store leftovers in the fridge for 4-5 days or freeze for 3 months in vacuum-sealed bags. I always slice it thin against the grain for restaurant-style presentation. The au jus reduces beautifully when reheated, so save some extra for dipping. Garnish with fresh herbs right before serving—nothing fancy, just a sprinkle—to keep everything vibrant.
Why You’ll Love This Recipe
- Two-Ingredient Magic: The salt and butter do all the heavy lifting here—no fancy blends or herbs needed. Just a thick coat of kosher salt, a slab of butter studded with garlic, and the Instant Pot handles the rest while you sip wine. (Yes, even on a Tuesday night.)
- Crowd-Pleasing Crust: That crispy, caramelized exterior? It’s not just pretty—it’s addictive. The high-heat sear in the Instant Pot locks in juices while building flavor, so every bite delivers that perfect contrast of tender meat and buttery, golden crust.
- Sunday Dinner Simplified: Honestly, this is my go-to for holidays and lazy Sundays. The same roast works for a family brunch (add eggs!), a game-day spread, or a fancy dinner—just adjust the sides. My kids even ask for it when I serve it cold the next day.
- Leftovers That Win: Between us, the best part might be the leftovers. Thinly sliced, it’s ridiculously good in sandwiches or tacos, and the fridge version stays juicy for days. I’ve sent this home with neighbors just to avoid eating it all myself. (Not the prettiest, but the taste makes up for it.)
Step-by-step instructions for Instant Pot prime rib roast
This method delivers melt-in-your-mouth prime rib with a perfect crust and juicy interior—no oven needed.
Prep the Prime Rib for Maximum Flavor
Begin by patting the 4 lb prime rib roast completely dry with paper towels. This step is critical—moisture on the surface prevents proper browning and crust formation. Place the roast on a cutting board and use a sharp knife to make small slits in the fat cap, being careful not to cut into the meat. This creates pockets for the seasoning to penetrate deeply.
In a small bowl, combine the 2 tbsp kosher salt and 1 tbsp freshly ground black pepper. Generously coat the entire surface of the roast with this mixture, pressing it into the slits and all sides. For extra tenderness, sprinkle 1 tbsp meat tenderizer evenly over the surface. Let the seasoned roast sit at room temperature for 30 minutes while you prepare the aromatics—this ensures even cooking from edge to center.
Sear the Prime Rib for Deep Flavor
Set your Instant Pot to the “Sauté” function and allow it to heat up completely. Add 2 tbsp beef tallow or olive oil and let it shimmer for 1 minute. Place the prime rib roast fat-side down in the pot and sear undisturbed for 8-10 minutes, pressing gently with a spatula to ensure full contact. This creates a flavorful crust that locks in juices during pressure cooking.
Flip the roast and sear the other side for another 6-8 minutes. Here’s the thing—don’t rush this step. You’re building layers of flavor that will make all the difference in the final result. Once both sides are deeply browned, remove the roast and set it aside on a plate.
Build the Herb-Infused Au Jus Base
In the same Instant Pot, add the 8 smashed garlic cloves, 0.25 cup chopped fresh rosemary, and 0.25 cup chopped fresh thyme. Sauté for 1 minute until fragrant—this releases their essential oils and deepens the flavor profile. Pour in the 0.5 cup red wine and scrape up any browned bits from the bottom of the pot with a wooden spoon. These bits are packed with flavor and form the foundation of your au jus.
Let the wine simmer for 2-3 minutes until reduced by half. This step concentrates the flavors and creates a rich base for your sauce. Add the 2 cups beef au jus and stir to combine. Return the seared prime rib to the pot, placing it fat-side up.
Pressure Cook to Perfect Tenderness
Secure the Instant Pot lid and set the valve to “Sealing.” Cook on High Pressure for 90 minutes. The Instant Pot will automatically switch to “Keep Warm” when done, maintaining the perfect temperature until you’re ready to serve. This long cook time ensures the prime rib reaches an internal temperature of 145°F—perfect for medium-rare—while keeping it impossibly tender.
Here’s where it gets interesting: during the last 15 minutes of cooking, the meat releases natural juices that create a self-basting effect. This is why you don’t need to add extra liquid—the prime rib essentially cooks in its own flavorful juices. The result is a roast that’s so tender it practically falls apart with a fork.
Rest and Serve with Horseradish Cream
Once the cooking cycle completes, allow the pressure to release naturally for 15 minutes, then quick-release any remaining pressure. Carefully remove the roast and transfer it to a cutting board. Tent loosely with aluminum foil and let it rest for 15-20 minutes. This resting period is crucial—it allows the juices to redistribute throughout the meat, preventing them from pooling on your plate.
While the roast rests, skim any excess fat from the cooking liquid in the Instant Pot and stir in the 0.5 cup horseradish cream. This classic pairing adds a bright, tangy contrast to the rich prime rib. Slice the roast against the grain into ½-inch thick portions and serve immediately with the au jus drizzled generously over the top. Each bite should be perfectly balanced—tender meat with a crispy exterior and a sauce that’s rich yet not overpowering.
Pro Tips For Making Instant Pot Prime Rib Roast
- Sear First, Then Salt: The Instant Pot’s lid traps steam, so skip salting the meat before searing—it’ll just melt off. Instead, coat the raw prime rib with kosher salt after browning, when the surface is dry enough to stick. I learned this the hard way after my first batch turned out bland because the salt dissolved into the butter before it could do its job.
- Use Cold Butter: Unsalted butter straight from the fridge makes a better crust than softened butter—it sizzles longer and creates those golden brown bits we all crave. Plus, cold butter won’t turn into a greasy mess when you dump it on top of the garlic. (Yes, even if you’re impatient like me.)
- Don’t Skip the Garlic: Those minced garlic cloves? Don’t just toss them in—sauté them in the Instant Pot for 30 seconds on high heat first. This builds flavor before the pressure cook, and it prevents them from turning to mush later. My grandmother swore by this, and she was right: the aroma alone makes the dish feel special.
- Rest It Properly: The prime rib needs a solid 5-10 minutes under foil before slicing—no cutting into it early, no matter how hungry you are. The juices redistribute during this time, or you’ll end up with dry slices. (Your future self will thank you.)
Health benefits of this instant pot prime rib roast
Protein Powerhouse
A 4 lb prime rib roast delivers an impressive 120 grams of protein per serving, making this dish ideal for muscle repair and satiety. Prime rib is one of the richest sources of complete protein, containing all nine essential amino acids your body needs for growth and recovery.
The Instant Pot method preserves this protein content while eliminating the dryness that often accompanies traditional roasting. 💪
Iron for Energy
Prime rib is an excellent source of heme iron, the most bioavailable form of this essential mineral. A single serving provides about 3.5 mg of iron—nearly 20% of your daily needs—supporting healthy red blood cell production and energy levels.
The Instant Pot cooking process doesn’t leach iron like boiling, so you retain all these benefits in every bite.
Heart-Healthy Fats
While prime rib contains saturated fat, the monounsaturated fats in the marbling actually support heart health when consumed in moderation. These fats help raise HDL (“good” cholesterol) levels and provide energy.
The key is balance—this recipe’s portion size and preparation method make it a special occasion treat rather than a daily staple. The red wine used in the au jus also contributes heart-healthy polyphenols.
Vitamin B12 Boost
Prime rib is one of the best natural sources of vitamin B12, with a serving providing over 100% of your daily requirement. This crucial vitamin supports nerve function, red blood cell production, and DNA synthesis.
The Instant Pot method preserves this vitamin content better than traditional oven roasting, which can cause some nutrient loss through surface browning.
Zinc for Immunity
This cut of beef is packed with zinc, an essential mineral that supports immune function and wound healing. A serving contains about 12 mg of zinc—more than 100% of the daily value for men and 80% for women.
The Instant Pot’s gentle cooking process helps retain this mineral better than high-heat methods, making each bite more nutrient-dense. 💡
Selenium Antioxidant
Prime rib contains significant amounts of selenium, a powerful antioxidant that protects cells from damage. A single serving provides about 50 mcg—nearly 100% of your daily needs. Selenium works synergistically with vitamin E to support heart health and thyroid function.
The Instant Pot’s even heat distribution ensures this antioxidant remains stable throughout cooking, preserving its benefits in every slice.

Frequently asked questions
Can I use this Instant Pot method for a different cut of beef?
While this recipe is optimized for prime rib, you could adapt it for other thick-cut roasts like top round or chuck roast. However, cooking times would need adjustment—thinner cuts may require 60-75 minutes on high pressure, while thicker cuts might need up to 2 hours. Always use a meat thermometer to check for 145°F for medium-rare.
Why does the recipe call for natural pressure release instead of quick release?
The 15-minute natural release is critical for prime rib because it allows residual heat to gently finish cooking the meat, ensuring even doneness throughout. Quick releasing can cause uneven temperatures and potentially overcook the center while the exterior cools too fast. This method also helps maintain moisture—skipping it risks a slightly drier roast.
What if my Instant Pot doesn’t have a “Sauté” function?
No problem! Use the “Manual” setting for 2 minutes to heat the pot and oil before adding your aromatics. This mimics the sauté function perfectly. Just be sure to add the roast immediately after the pot comes to temperature to start searing right away. The cooking time remains the same—just adjust the initial heating method.
How do I prevent the prime rib from drying out?
The key is the resting period—never skip the 15-20 minutes under foil. Also, avoid overcooking: use a meat thermometer to check for 145°F (medium-rare) and never exceed 150°F. The Instant Pot’s pressure cooking actually preserves moisture better than traditional methods, but proper searing and resting are still essential for that perfect texture.
Can I make this ahead of time for a holiday meal?
Cook the prime rib up to 2 days ahead and refrigerate it tightly wrapped. Reheat in the Instant Pot on “Sauté” for 5-8 minutes with a splash of beef broth to maintain moisture. For best texture, slice just before serving. The flavors actually improve overnight as they meld together—perfect for stress-free holiday prep!
