Cover chicken halfway with water and simmer until tender. Remove, cool, bone and chop chicken into bite-sized pieces.
In a large skillet, brown chopped onion and garlic in butter over medium heat. Remove garlic clove and discard.
Add chopped chicken, cumin, and picante sauce to the skillet. Season with salt and pepper to taste and simmer for 5 minutes.
Soften corn tortillas on a hot, well-oiled griddle until pliable.
Fill each tortilla with chicken mixture and some grated cheese, reserving 2 cups of cheese for topping. Roll tightly and place seam-side down in a greased 13 x 7 1/2 inch casserole dish.
In a bowl, mix cream of chicken soup, sour cream, and cumin until smooth. Pour evenly over the enchiladas.
Top with remaining 2 cups of cheese, sliced jalapeño peppers, and sprinkle with paprika.
Bake at 350°F until hot and bubbling, approximately 25-30 minutes.
