Prime rib tacos are a delicious way to enjoy any leftover prime rib. Just dice up the meat and pile it on tortillas with avocado slices, salsa, queso fresco, cilantro and lime juice. Super easy!

If you made prime rib for a holiday feast, like Thanksgiving or Christmas, and purchased an extra large standing rib roast (as I often do), you may have some leftovers. Of course, you can reheat those prime rib slices and serve them straight-up with a few sides….or you can turn them into the MOST delicious prime rib tacos.

Trust me, medium-rare prime rib is a glorious treat piled inside tacos. There’s just something about that garlic herb meat flavor mixed with homemade salsa, creamy avocado, and crumbly queso fresco – it’s divine.

Now I’ll be the first to admit these aren’t your everyday tacos, given how pricey prime rib is. But when you do have leftovers, do yourself a favor and whip these up. You’ll be so glad you did!

Prime Rib Taco Ingredients

With the meat already cooked, this recipe is a breeze to make. Here’s what you’ll need:

  • Prime Rib: just thaw and/or warm up a slice of leftover prime rib, then dice it up.
  • Avocado: creamy avocado always deserves a spot in tacos. But you could also use guacamole.
  • Salsa: I used my restaurant-style salsa recipe which has a more liquid consistency, but you could use chunky pico de gallo – it’s up to you.
  • Queso Fresco: a soft, moist, slightly salty cheese that’s perfect for crumbling on tacos.
  • Cilantro: fresh cilantro is a necessity in any Mexican-inspired recipe.
  • Lime Juice: a squirt of fresh lime juice on top adds a lovely sour kick!
  • Tortillas: I’m using my homemade cassava flour tortillas, but feel free to use your favorite store-bought tortillas as well.

How Much Prime Rib Per Taco

I’d estimate about one thick slice of prime rib for two tacos. Your prime rib might be slightly bigger or smaller than mine, and your slices might be cut thicker or thinner, varying the quantity a little.

How to Make These Tacos

There’s not much to make with this recipe, it’s more assembly than anything. And who doesn’t love that?

Just add a tortilla to a plate, pile on a good amount of diced up prime rib, then top that with a few avocado slices, a generous dollop of salsa, a crumble of queso fresco, fresh cilantro leaves and a squirt of lime juice. Done!

The Best Christmas Prime Rib Tacos

Are Christmas tacos a thing? Oh, probably not, but I say we change that. You don’t have to eat these on Christmas (that’s when you’re eating your standing rib roast anyway). But the next day, the following weekend, or the following taco Tuesday all sound perfectly appropriate to me to make these prime rib tacos!

  1. I make prime rib tacos every time I roast a prime rib. I always use fried corn tortillas and slfold them in half as I fry them. I also use cilantro, but in pico de gallo, lettuce, guacamole and graded cheese or Queso blanco. Mmmmm. They always come out delicious. 5 stars

  2. Have you ever cut a prime rib so you season with seasoned butter and roll up the rib, tie it then smoke or roast it?

  3. this gets put on the list of leftover makeover meals. It looks and sounds amazing. And I never thought of it even though I put almost anything in a taco.5 stars

  4. Had this for dinner tonight, it was delicious. First time making the tortillas and they turned out awesome, hubby was so impressed. Thank you, Lisa, you make me a better cook.5 stars

  5. Your timing couldn’t be better. Yes, I bought a big roast and yes, I have lots of leftovers. Reheating is fine but making tacos is a much tastier option. Yum!5 stars
