Step-by-Step Guide to Your Au Jus Prime Rib Roast (Air Fryer)

Okay, buckle up, because this is where the magic really happens! Making prime rib in the air fryer is surprisingly straightforward, and remember, this process, especially the au jus part, is your secret weapon for the juiciest prime rib roast. We’re going to break it down into simple steps so you can’t mess it up!

Preparing the Prime Rib Roast

First things first, grab your roast and pat it totally dry with some paper towels. Don’t skip this – it helps get a nice crust! Then, in a little bowl, mix up your olive oil with the garlic powder, onion powder, salt, and pepper. Get your hands in there and rub that glorious mixture all over the roast. Get into all the nooks and crannies!

Cooking the Prime Rib in the Air Fryer

Preheat your air fryer to a nice hot 400°F (200°C). Pop that seasoned roast in there, bone-side down, and let it cook for about 15 minutes. This initial blast of heat really gets things going. After that, turn the heat down to 300°F (150°C). Now, let it cook for another 45 minutes or so, depending on the size of your roast – aim for about 12-15 minutes per pound. The best way to know for sure? Use a meat thermometer! You’re looking for an internal temperature of around 120°F (49°C) for rare or 130°F (54°C) for medium-rare. I’ve linked to my favorite air fryer teriyaki chicken recipe as a reference for cooking times, but always go by your thermometer!

Resting the Roast for Maximum Juiciness

This is SO important! Once it hits your target temp, carefully take that beauty out of the air fryer and put it on a cutting board. Tent it loosely with some foil and let it hang out for a good 15 minutes. Seriously, don’t cut it right away! This resting time lets all those delicious juices redistribute through the meat.

Crafting the Perfect Au Jus

While your roast is resting and getting all juicy, let’s whip up that amazing Au Jus. Grab a small saucepan and pour in your beef broth, that optional red wine (if you’re using it, it’s sublime!), Worcestershire sauce, and minced garlic. Tuck in that rosemary sprig if you like. Bring it all to a gentle simmer over medium heat and let it bubble away for about 5-10 minutes. This lets all those flavors get friendly. Just remember to pull out that rosemary sprig before you serve!

Tips for Air Fryer Prime Rib Success

Okay, so you’ve got the recipe, but let’s talk about making sure your Air Fryer Prime Rib comes out absolutely perfect, every single time. It’s not just about following steps, it’s about understanding a few little tricks that really make a difference. Remember, the Au Jus is your secret weapon for the juiciest prime rib roast (air fryer), but a few pro tips will make the roast itself shine!

First off, air fryer size matters! Make sure your prime rib will actually *fit* comfortably in the basket. If it’s too snug, the air won’t circulate properly, and that’s when you might get uneven cooking. I learned that the hard way trying to cram a bigger cut into my old air fryer. These days, mine is a lot more forgiving. Also, don’t be afraid to season that beautiful roast ahead of time! I like to rub it down and pop it in the fridge, uncovered, for a few hours—or even overnight. It really helps the flavors sink in and that initial sear get even better. It’s kind of like how I prep my chicken for these amazing sheet pan fajitas; a little advance prep goes a long way!

And please, please, please invest in a good meat thermometer. Seriously, it’s the most reliable way to nail your desired doneness. Those little dial ones on some air fryers aren’t always accurate, and you don’t want to guess when it comes to a cut like prime rib. Trust me, it’s worth every penny for perfectly cooked meat!

Serving Suggestions for Your Prime Rib Feast

Now that you’ve nailed that perfect prime rib with its amazing au jus, what do you serve with it? You want sides that complement the richness without overwhelming it. Honestly, a classic roast vegetable lasagna like this one is always a winner because it’s hearty and delicious. Or, for something a little more elegant, a creamy mushroom risotto, like this recipe, is just divine and soaks up that extra au jus like a dream! Don’t forget some simple steamed greens or a baked potato, and you’ve got a feast fit for royalty!

Storage and Reheating Instructions

Got leftovers? Lucky you! Store any leftover prime rib and au jus in airtight containers in the fridge. The roast is best eaten within 2-3 days. Reheat gently! For the roast, I like to warm it up in a skillet over low heat with a splash of the au jus, or pop it back in the air fryer for just a few minutes at a low temp—just to warm it through, you don’t want to cook it more. The au jus can be gently reheated on the stovetop.

Frequently Asked Questions About Au Jus Prime Rib Roast (Air Fryer)

Got questions? I’ve got answers! Cooking a prime rib, especially in the air fryer with its own special au jus, can bring up a few things. Let’s clear up any confusion so your Au Jus Prime Rib Roast (Air Fryer) experience is absolutely perfect!

Can I use a different cut of beef instead of prime rib for this recipe?

While this recipe is specifically designed for prime rib because of its marbling and tenderness, you could try something like a ribeye roast or a simpler top sirloin roast. Just be aware that cooking times and results might vary significantly. For the best juicy outcome using the Au Jus—your secret weapon for the juiciest prime rib roast (air fryer)—sticking with prime rib is your best bet!

My air fryer is pretty small. Will a prime rib roast fit?

That’s a great question! Air fryer sizes really differ. You absolutely need to make sure your roast can fit comfortably in the basket without touching the sides. If it’s too snug, the air won’t circulate properly, and you won’t get that even, beautiful cook. You might need to look for a smaller roast (like 2-3 pounds) or consider a different cooking method. But if it fits, this air fryer method for our Au Jus Prime Rib Roast is fantastic!

How do I adjust the cooking time for different sizes of prime rib roasts?

The rule of thumb is roughly 12-15 minutes per pound at the 300°F (150°C) setting after the initial sear. So, if you have a slightly smaller roast, cut down the time. For a larger one, add more time. The absolute best way to nail it is to use a reliable meat thermometer. You’re aiming for 120°F (49°C) for rare and 130°F (54°C) for medium-rare *before* resting. That thermometer is your best friend for this Au Jus Prime Rib Roast (Air Fryer)!

Can I make the Au Jus ahead of time?

Yes, you absolutely can! The au jus is quite forgiving. You can make it a day in advance and store it in an airtight container in the refrigerator. When you’re ready to serve, just gently reheat it on the stovetop over low heat until warmed through. Then your Au Jus—your secret weapon for the juiciest prime rib roast (air fryer)—will be ready to go!

Nutritional Information

Okay, so diving into the nitty-gritty of nutrition! These numbers are just estimates, of course. What you use – like the type of beef, how much wine you add to the au jus, or even the brand of broth – can change things up a bit. But generally, you’re looking at about [insert estimated calories] calories, [insert estimated protein] of protein, [insert estimated fat] of fat, and [insert estimated carbs] of carbs per serving.
