Instant Pot Mexican Shredded Chicken

This Instant Pot Mexican Shredded Chicken is easy to make with minimal effort. Chicken simmers with tomatoes, green chiles, and spices until it’s fall apart tender with all those delicious Mexican flavors.

The entire dish comes together in about 35 minutes, making it perfect for busy weeknights. Use it in tacos, fill burritos, top rice bowls, or just serve it over rice for a meal everyone will enjoy.

I make this Instant Pot Mexican Chicken all the time at our house. The flavors remind me of my favorite Mexican restaurant, but I can create them right in my kitchen. I love serving it in warm corn tortillas for taco night or over a bowl of rice.

Instant Pots are truly amazing kitchen tools! Before I got mine, making tender, flavorful shredded protein meant hours of slow cooking. Now I can decide at 5:30 that I want Mexican chicken for dinner, and we’re eating by 6:00. The pressure cooking method locks in moisture and infuses all those delicious spices throughout the meat.

The leftovers might be even better than the first serving. I often make a double batch specifically for meal prep; it stores beautifully and saves me from the midweek cooking slump.

My favorite way to serve this chicken is taco-style with plenty of toppings. I love piling on sliced avocados, shredded cheese, a dollop of sour cream, and thin slices of jalapeños for some heat. 

You might want to serve it with diced red onions, chopped fresh tomatoes, cilantro, or a squeeze of lime juice, too. A simple cabbage slaw dressed with lime juice adds the perfect crunch.

Ingredient Notes

See the printable recipe card below for all ingredients, specific measurements, and complete instructions.

• Chicken breasts: I used boneless chicken breasts, but you can also use boneless chicken thighs instead for a juicier option.
• Taco seasoning: I used a store-bought mix for convenience, but feel free to use a homemade version for more control over spices. This is especially helpful if you prefer to adjust the heat and salt levels.
• Chicken broth: Use vegetable broth or water with a bouillon cube as an alternative option.
• Diced tomatoes: These provide liquid and flavor. Fire roasted tomatoes can add deeper, smokier flavor if you have them available.
• Green chiles: These add a mild heat and authentic flavor. For a milder version, you can swap these for diced bell peppers.
• Onion and garlic: These aromatics create the flavor foundation. Yellow or white onions work best, but red onions are fine too if that’s what you have on hand.
• Olive oil: Any neutral cooking oil works here. The oil helps sauté the aromatics to release their flavors before pressure cooking.
• Cilantro and lime: While optional, I love these fresh ingredients on the finished dish. If you’re not a fan of cilantro, you can leave it out.

How To Make Instant Pot Mexican Shredded Chicken

Begin by pressing the Sauté button on your Instant Pot. Once hot, add olive oil and cook the diced onions for 3-4 minutes until softened. Add the garlic and cook for just 30 seconds more to prevent burning.

Pour in the chicken broth and scrape the bottom of the pot to remove any stuck bits; this prevents the “burn” notice during cooking. Add diced tomatoes, green chiles, and taco seasoning, then stir to combine.

Place the chicken breasts in the liquid, making sure they’re partially submerged for even cooking. Close the lid, set the valve to “Sealing,” and select Pressure Cook for 12 minutes. When cooking is complete, allow for a 10-minute natural pressure release for a more tender chicken.

After the 10-minute natural release, carefully turn the valve to the “Venting” position to release any remaining pressure. Once the float valve drops, open the lid and remove the chicken to a cutting board. Shred it using two forks; it should pull apart easily.

Return the shredded chicken to the pot and stir it back into the sauce to allow it to absorb more flavor. Garnish with fresh cilantro if desired and serve with lime wedges for a bright finishing touch.

Make Ahead, Storing and Freezing

Make Ahead: You can prepare the dish completely and refrigerate for up to 2 days before serving. 

Store: Place leftover Mexican Chicken in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat or microwave until heated through.

Freeze: Transfer cooled chicken to freezer-safe containers and freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.

Variations

• Try different proteins. This same method works beautifully with boneless pork shoulder (cook for 25 minutes) or even with beef chuck roast (cook for 35 minutes) for delicious Mexican-style shredded meat.
• Make it spicy. Add 1-2 diced jalapeños with the seeds, a teaspoon of cayenne pepper, or a tablespoon of hot sauce to kick up the heat level.
• Slow cooker method. No Instant Pot? Use a slow cooker instead. Sauté the onions and garlic in a pan first, then transfer everything to a slow cooker and cook on low for 6-7 hours or high for 3-4 hours.

Recipe Tips

• For the best flavor, sauté the onions and garlic before adding other ingredients. This small step makes a big difference in the final taste.
• Make sure to scrape the bottom of the pot after adding the chicken broth to remove any browned bits. This prevents the “burn” notice and adds flavor to your sauce.
• If you prefer a thicker sauce, after shredding the chicken, set the Instant Pot to Sauté mode and simmer until the desired consistency is reached.
• For a quick meal prep option, double the recipe and portion it into containers with rice or cauliflower rice for easy lunches all week.
• Frozen chicken works too! Just increase the cooking time to 18-21 minutes and make sure the chicken reaches 165°F internally before shredding.
• For a milder version, use mild taco seasoning and replace green chiles with bell peppers.

How can I thicken the sauce?

If your sauce seems too thin after cooking, remove the shredded chicken temporarily. Set the Instant Pot to Sauté mode and simmer the sauce for 5-10 minutes until it reduces to your desired consistency. Then return the chicken to the pot and stir to combine.

Can I add vegetables to this recipe?

Absolutely! Bell peppers, corn, or zucchini make great additions. For firmer texture, add them after the pressure cooking is complete. Set the pot to Sauté mode after shredding the chicken, add the vegetables, and cook for 3-5 minutes until tender but not mushy.

This Instant Pot Mexican Shredded Chicken recipe saves so much time on busy nights! I love having it ready in about 35 minutes and being able to use it in different ways throughout the week.

The combination of shredded chicken with those classic Mexican seasonings works perfectly for tacos, burritos, or simply served over rice. It’s become one of my regular recipes because it’s so practical, quick to make, easy to store, and always delicious.
