This is an Instant Pot chicken enchiladas recipe that is made with tender chicken in a pressure cooker with green chiles, onion, and spices and then wrapped in flour tortillas, topped with homemade enchilada sauce, and baked in the oven.
Add chicken, chicken broth, green chiles, onion, cumin, garlic powder, and salt to Instant Pot and set to Meat/Stew setting, on 'more' (or high), for 15 minutes (For larger chicken breasts they may need to go 20 minutes.) Once done, quick release and shred the chicken with a fork and mix with sour cream.
Meanwhile, make enchilada sauce in a saucepan over medium-high heat by adding vegetable oil and whisking in flour. Slowly add chicken broth while continuing to whisk. Add tomato paste, all seasonings, and bring to a simmer for 5 minutes.
Preheat oven to 400 degrees Fahrenheit. In a 13" x 9" baking dish, spread an even layer of enchilada sauce. Make each enchilada by spreading a teaspoon of enchilada sauce in the center of each tortilla followed by approximately ¼ cup of chicken mixture. Top with shredded cheddar cheese and queso fresco.
Bake in the oven for 20 minutes. Spread enchilada sauce on top prior to serving.
