With the New Year right around the corner, I’m here to share an amazing recipe to use up your leftover prime rib. Quick, easy, and super delicious, this is a great way to use up leftovers for a hearty lunch on New Year’s Day. Give these prime rib and horseradish guacamole tacos, hot off the Traeger, a try in the New Year!
PRIME RIB FOR NEW YEARS
One of the most decadent and delicious ways to ring in the New Year is sharing a great meal with family and friends. Prime Rib roasts are often on sale this time of year (because of their popularity) and I suspect that many of you have a prime rib prepped for New Year’s Eve enjoyment. If you’re still on the fence, here are a few prime rib recipes I can share for inspiration:
- Smoked-fried prime rib on the Traeger
- Prime Rib with caramelized onion and horseradish sauce

CROSS YOUR FINGERS FOR LEFTOVERS
When we cook up something big and delicious like a prime rib, we often have our fingers crossed that there will be some– even a little bit– leftover. It’s always great to have leftovers on hand because of the versatility that leftovers provides. It allows you to cut the corners (and make a meal more quickly) while repurposing a protein like prime rib for the next meal.
TACOS ARE ALWAYS A GOOD IDEA
I don’t know that we’ve ever been disappointed by a cutting board full of tacos made of leftovers. Whether it’s chicken, pulled pork, brisket or prime rib, the base protein is always delicious and cooked perfectly on the Traeger and takes on myriad new flavors with the additions you pick to create tacos. From sauces to salsas, the sky is the limit.
START WITH A GREAT TORTILLA
A great taco is elevated to new heights with terrific tortillas. You can find them often at local ethnic markets, where they’re usually made on site and by hand. But I also recommend you try these mail-order tortillas that our family is obsessed with.
My friend Reuben makes Caramelo Tortillas in Lawrence, KS in the traditional Sonoran-style. Thin, tender and full of flavor, these tortillas take tacos to the next level. We love their flour tortillas– in duck fat, pork fat and avocado oil. But their flour tortillas are also epic and great to have on hand.
We usually order 8-10 packs of the tortillas at one time and then keep them on hand in the freezer for moments like tonight when tacos are on the menu.
LEANING ON FUSION FLAVORS
As we were brainstorming ways to use leftover prime rib in tacos tonight, we wanted to blend some different and unique flavors to make something great. At our house, prime rib is usually served with a spicy horseradish sauce, which we make at home.
And we think there’s no better topping to tacos than guacamole– so this was the chance to blend the two. Substituting horseradish for the jalapeño peppers, we whipped together a great horseradish guacamole. Give it a try!
PULL IN SOME TRADITIONAL ELEMENTS
As we were debating what to put in our tacos, we realized that we could easily have done a “French Dip Taco” which would essentially be a French dip sandwich but on a tortilla. We didn’t have any au jus left, though, so that would be a bit harder to do.
But a great French Dip sandwich includes tender meat, sautéed onions and melted cheese. So we used those three elements as the base for the tacos, adding in the fusion flavor of the guacamole for a different twist.
COOK IT ALL UP ON THE TRAEGER FLATROCK
The great thing about cooking with leftovers is that a huge chunk of the effort and time is behind you when you open the fridge. We didn’t need to slow smoke anything for tongiht’s dinner, making it possible to get the family fed in under 15 minutes.
This was especially possible because of the Traeger Flatrock Griddle— which is such a great addition to our Traeger arsenal. With three distinct cooking zones and a huge cast iron cooking surface, the Flatrock makes it possible to cook so many different, interesting and delicious things in a matter of minutes.
After sautéing the onions in a bit of butter on the griddle, we added the cubed Prime Rib and cooked that until golden and heated through. As the cheese begins to melt into the meat and onions, we heated up the Caramelo tortillas in the other zone. All of this happened very quickly and meant dinner- Prime Rib tacos on the Traeger- was ready in a snap!
