Preheat oven to 400
Place the chicken, water, onion, garlic, oregano, salt and pepper in the Instant Pot. Set for 10 minutes and allow for natural release.
Remove the chicken, allow to cool, shred and set aside.
Reserve the remaining ingredients in the Instant Pot and place in blender with the cream cheese, chipotle peppers, salt and pepper to taste.
Blend until smooth.
Warm the tortillas on a hot skillet sprayed with oil. It helps make them pliable and stay together and not fall apart.
Start building your enchiladas by pouring some of the sauce in your pan or casserole (I used a cast iron pan).
Reserve enough sauce and cheese to cover the top of your enchiladas.
Place a warm tortilla on a cutting board or clean counter, stuff with chicken, cottage cheese, some sauce and cheese. Place in pan.
Repeat until you've made all 8 of your enchiladas.
Pour the remaining sauce and sprinkle with remaining cheese.
Bake for 25 minutes until bubbly and golden brown.
