How Long do I Cook Prime Rib for Medium-Rare?
This easy prime rib recipe is so tender and perfectly medium-rare, thanks to the use of a meat thermometer. It goes like this: put it in the oven at one temperature, lower the temperature, and when the thermometer beeps, take it out. Simple as it gets, right? I tried a couple of other methods first, before perfecting this easy prime rib recipe, and I can assure you: this is the most tender and all-around best prime rib I’ve had at home. Or maybe… anywhere? Big claim!
So focus less on the time it takes to cook this prime rib and more on the thermometer! You’ll cook the prime rib for 15 minutes at 450º, then reduce heat to 325º F. You’ll cook it until internal temperature is 113-115º F for very medium-rare. The roast will continue cooking after removing from oven when you let it rest 20 minutes while you make the au jus.
Au Jus Sauce for Prime Rib
The au jus to go with this easy prime rib recipe is equally easy: stir in a few things, let it simmer a bit, and voilà: rich and flavorful au jus to serve alongside your roast. I will literally drink a good au jus, and this au jus recipe is super easy, quick, and oh so savory.
You might be used to au jus from the little bottle at the store but it’s so, so much better made at home.
How Do You Make Au Jus at Home?
This au jus recipe is way easier than even making a little packet! To the pan, after you’ve removed the prime rib, add Worcestershire sauce and red wine and reduce slightly, by about 1/4. Add beef broth and continue to simmer until reduced to desired consistency. Carefully tilt the roasting pan and, using a spoon, discard excess fat floating on top. Carve roast and serve with the au jus recipe!
This homemade horseradish sauce is so much better than store bought ad comes together so quickly.
I let the sauce chill a couple of hours, and it was great, but 24 hours later? It was next level. I highly recommend letting the sauce chill for 24 hours before serving, but if you can’t swing that, give it at least 1 hour in the fridge. You’ll get it when you taste the stuff!
