Gather the ingredients for 5-ingredient Costco tacos

Our 5-ingredient Costco tacos are filled with the sweet and spicy flavors of pineapple, avocado, and habanero peppers. How is all that possible with so few ingredients?

These tacos owe their flavor to one magic ingredient: Robert Rothschild Roasted Pineapple and Habanero Sauce, which you can find at Costco. With its sweet and spicy combination of flavors and the aroma of roasted pineapple, this little sauce packs a mighty punch that will be sure to elevate your tacos.

The other ingredients you’ll need for these easy Costco tacos are one fresh pineapple, a ripe avocado, corn tortillas, and one of those famous Costco rotisserie chickens, which should be more than enough to make about 2 cups of shredded chicken meat.

Dice the pineapple and shred the chicken for 5-ingredient Costco tacos

As there are so few ingredients in these 5-ingredient Costco tacos, the instructions here are pretty simple. First off, start by peeling and dicing the fresh pineapple. To peel a pineapple, cut off about ½ an inch below the top of the pineapple, where all the leaves are. Then, cut off about ½ an inch from the base of the pineapple.

Now, moving your chef’s knife in a slight curve, begin to cut off the rough outer surface of the pineapple. Remove any of the remaining tough brown parts you see until you get to the perfectly yellow, sweet flesh.

Finally, locate the core of the pineapple. Cut with your knife in a smooth motion from top to bottom around the core, leaving you with 4 sides of the pineapple and the core. Discard the core, the peel, and the leaves from the top. Dice ¼ of the pineapple into small chunks. They should be of a size you wouldn’t mind biting into in a taco, about 1/2 inch or less.

Now, shred the Costco rotisserie chicken, making enough to fill 2 cups. That typically comes out to about half a chicken breast, so chances are good that you won’t need to shred the whole thing.

Mix diced pineapple with sauce

In a medium bowl, mix the diced pineapple with 2 tablespoons of Robert Rothschild Roasted Pineapple and Habanero Sauce. What you’re doing here is seasoning the sweet, tangy fresh pineapple with a very concentrated sauce of roasted pineapple and habanero peppers. This adds a deep note of caramelization to our pineapple sauce, as well as a nice, spicy finish. You’ve just created a pineapple salsa that’s worthy of any 5-star taqueria, and only with about ½ a minute of work in your own home.

Taste and add salt or more Robert Rothschild Roasted Pineapple and Habanero Sauce as necessary.

Mash and season avocado for 5-ingredient Costco tacos

For the perfect balance of textures, we’re going to mash our avocados into a creamy consistency. This texture will contrast really nicely with the soft rotisserie chicken and the chunky pineapple salsa.

To make mashed avocado, you’ll first off need those elusive perfectly ripe avocados. We recommend ripening your avocados outside the fridge. When you feel like the avocado has a bit of give when you press on the outer skin, transfer them to the fridge. This slows down the ripening and helps prevent you from ending up with blackened, rotten avocado before you’re ready to use them.

Cut the avocado in half — remember to go slow and avoid injuring yourself — remove the pit with a spoon, and scoop out the avocado meat. Transfer the avocado meat to a bowl and mash with a fork. Season with a bit of salt.

Toast the tortillas for 5-ingredient Costco tacos

The perfect tacos require warm, pliable corn tortillas. So even if you’re making 5-ingredient Costco tacos in under 10 minutes, we recommend that you take the extra time to warm up your tortillas. It can make all the difference between passable tacos to an amazing, authentic dish you’re going to be raving about for weeks. And, honestly, it doesn’t take all that much longer to really up your tortilla game in this manner.

To toast tortillas the traditional way, use the stovetop. Bring a small pan to medium heat and, when it’s hot, toast each tortilla on both sides. This will take about 30 seconds to 1 minute per side. If your oven is going already, you can also heat them up on a low grill setting, or any desired temperature for about 2 minutes.

Finally, on days you’re feeling really lazy, warm your tortillas in the microwave for 30 seconds. We won’t judge.

Assemble 5-ingredient Costco tacos

The time has come to assemble these amazing 5-ingredient Costco tacos. Rejoice!

To assemble the tacos, set yourself up in an area with plenty of counter space. This can be your table, a kitchen island, or just a counter. Place all the ingredients around you — this is a handy chef trick called mise in place, by the way — and place an empty plate at the end of the line. This is where you’ll put the assembled tacos. Leave yourself with a cutting board or clean space in the middle where you can assemble the tacos.

To assemble each taco, top a tortilla with 1-2 tablespoons of mashed avocado, then 2 tablespoons of shredded chicken, and 2 tablespoons of pineapple-habanero salsa. You can even drizzle with a bit more Robert Rothschild Roasted Pineapple and Habanero Sauce as you see fit. Repeat until you run out of corn tortillas.

Serve your 5-ingredient Costco tacos immediately

Tacos are best served fresh, and these 5-ingredient Costco tacos are no exception. We recommend serving these amazing Costco tacos immediately, perhaps with a big glass of ice-cold margarita alongside you. To make a great, easy pineapple margarita, you can blend some leftover pineapple in a pitcher with some ice, tequila, a pinch of salt, and even a bit of that roasted pineapple sauce. You can thank us later.

With one bite, you’ll be transported to the seaside of the Pacific Ocean, a happy cumbia playing in the background, the sand tickling your toes, and the wind whipping your hair about with salty sea spray. A tropical vacation in the middle of winter? Don’t mind if we do.
