Ingredients

1 tablespoon extra-virgin olive oil, divided
2 pounds boneless, skinless chicken breasts (about 4 small/medium or 3 medium/large), cut in half if large
1 ½ teaspoons kosher salt, divided
½ teaspoon ground black pepper
1 small yellow onion or 1/2 large yellow onion, thinly sliced
4 cloves garlic, minced
2 teaspoons chili powder
3 chipotle peppers in adobo, individual peppers, NOT 3 cans, finely chopped (if you love heat, feel free to add an extra pepper or stir in a few teaspoons of sauce from the can)
1 can diced tomatoes in their juices (14 ounces)
¼ cup freshly squeezed lime juice from about 1 medium lime
1 ripe avocado, peeled and pitted
¾ cup nonfat plain Greek yogurt
2–4 tablespoons fresh lime juice
¼ teaspoon kosher salt
Tortillas or taco shells of your choice
Any other bonus toppings: fresh cilantro, diced jalapeño, thinly sliced radishes, cheese, additional salsa, diced avocado (either in place of or in addition to avocado sauce above)

Equipment

6-quart or larger Instant Pot or electric pressure cooker
Wooden spoon or silicone spatula
Tongs
Forks for shredding
Blender or food processor for the avocado sauce

Prep tips

Trim any visible fat from the chicken breasts and cut larger breasts in half so they cook evenly. Finely chop the chipotle peppers—three individual peppers (not three cans) add a rich, smoky heat. If you want milder tacos, start with two peppers and add more as desired. Use the fresh lime juice specified in the ingredient list for the brightest result in both the cooking liquid and the avocado sauce.

Step-by-step Instructions

Follow these clear, sequential steps to make the best Instant Pot Shredded Chicken Tacos.

Turn the Instant Pot to the SAUTÉ setting and add 1/2 tablespoon extra-virgin olive oil. Allow the pot to heat for about 1 minute until the oil shimmers.
Season both sides of the chicken breasts with 1 teaspoon of the kosher salt and the ½ teaspoon ground black pepper.
When the oil is hot, add the seasoned chicken breasts in a single layer. Sear them for 1–2 minutes per side until lightly golden; you’re just giving them a bit of color. Remove the chicken to a plate and set aside.
Add the remaining 1/2 tablespoon extra-virgin olive oil to the pot. Add the thinly sliced onion and a pinch of the remaining salt. Sauté the onion, stirring occasionally, for 2–3 minutes until it begins to soften and turn translucent.
Stir in the minced garlic, 2 teaspoons chili powder, and the finely chopped 3 chipotle peppers in adobo. Cook for 30–45 seconds until fragrant—this helps bloom the spices and meld the smoky pepper flavors with the onion and garlic.
Pour in the 14-ounce can of diced tomatoes with their juices, scraping any browned bits from the bottom of the pot with a wooden spoon. This deglazing step prevents a burn warning later and adds flavor to the cooking liquid.
Return the seared chicken breasts to the Instant Pot, nestling them into the tomato mixture. Pour the ¼ cup freshly squeezed lime juice over the chicken, then sprinkle the remaining ½ teaspoon kosher salt across the top.
Lock the Instant Pot lid in place and set the valve to SEALING. Select the MANUAL or PRESSURE COOK setting on high pressure and set the timer for 10 minutes.
When the cook time finishes, allow the Instant Pot to naturally release pressure for 5 minutes. After 5 minutes of natural release, carefully move the valve to VENTING to release any remaining steam. Open the lid when the float valve drops.
Using tongs, transfer the cooked chicken breasts to a large bowl or cutting board. Use two forks to shred the chicken into bite-sized pieces. If you want extra flavor, spoon a few of the cooking juices over the shredded chicken to keep it moist.
Optionally, switch the Instant Pot back to SAUTÉ and simmer the tomato-onion mixture for 2–3 minutes to reduce and concentrate the sauce. Then return the shredded chicken to the pot and stir to coat with the sauce, or simply serve the juices on the side for guests to spoon over their tacos.
Prepare the avocado-lime sauce: In a blender or food processor, combine the ripe avocado, ¾ cup nonfat plain Greek yogurt, 2–4 tablespoons fresh lime juice (start with 2 tablespoons and add more to taste), and ¼ teaspoon kosher salt. Blend until smooth and creamy. Taste and adjust lime or salt as desired.
Warm tortillas or taco shells according to package directions, or heat them in a skillet for a minute per side until pliable and slightly charred.
Assemble tacos: Fill each tortilla or shell with a generous portion of shredded chicken, drizzle or dollop the avocado-lime sauce, and garnish with your favorite toppings such as fresh cilantro, diced jalapeño, thinly sliced radishes, shredded cheese, extra diced avocado, or additional salsa.

Serving suggestions

These tacos are wonderful with a side of Mexican-style rice, a crisp cabbage slaw, or a simple black bean salad. For a lighter plate, serve with a mixed green salad dressed in lime vinaigrette. Leftovers keep well—store shredded chicken in an airtight container with some of the cooking juices and it will stay juicy for 3–4 days in the refrigerator.

Make-ahead and storage

You can make the chicken a day ahead and reheat it gently on the stovetop with a splash of the reserved cooking liquid or in the microwave with a damp paper towel to keep it moist. Avocado-based sauces are best made the day you plan to serve them, but if you must make it ahead, add a little extra lime juice and press plastic wrap directly onto the surface to minimize browning.

Flavor variations

Smokier: Stir in an extra chipotle pepper or a teaspoon of adobo sauce for a deeper smoky heat.
Milder: Omit or reduce the chipotle peppers and serve with additional salsa for guests who prefer less heat.
Herby twist: Fold chopped fresh cilantro into the shredded chicken before serving for an herby lift.
Cheesy: Top tacos with shredded cheddar, Monterey Jack, or crumbled queso fresco for a richer bite.

Notes and troubleshooting

If you get a BURN or SCORCHED notice on your pressure cooker, release pressure, open the lid, and deglaze the bottom of the pot thoroughly, making sure no browned bits remain. Then reseal and continue cooking as directed. If your chicken breasts are exceptionally large and thick, cutting them in half (as noted in the ingredients) ensures even cooking and faster shredding.

Why the ingredient choices matter

Extra-virgin olive oil builds flavor during the brief searing step and helps the onions soften without adding heavier fats. Using two pounds of boneless, skinless chicken breasts yields a large batch perfect for family dinners or meal prep. The chili powder works alongside the chipotle peppers to create depth: chili powder provides earthiness while chipotles contribute smoke and a long, warm finish. Fresh lime juice brightens both the cooking liquid and the avocado sauce, cutting through richness and tying the flavors together.
