Step 1

Preheat the oven to 350 degrees F (175 degrees C).

Step 2

Fill a large pot with lightly salted water and bring to a rapid boil. Cook egg noodles at a boil until tender yet firm to the bite, 7 to 9 minutes.

Step 3

Meanwhile, place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon slices on paper towels. Crumble.

Step 4

Heat oil in a skillet over medium-high heat. Place chicken in the hot skillet, sprinkle with lemon-pepper, and brown on all sides, 5 to 7 minutes. Remove with a slotted spoon and place in a 9x13-inch baking dish.

Step 5

Combine 1/2 of the crumbled bacon, sour cream, soup, milk, and ranch dressing mix in a bowl and mix until blended. Pour over chicken, add drained egg noodles, and stir. Sprinkle remaining bacon on top, cover with Colby-Jack cheese, and top with green onions.

Step 6

Bake in the preheated oven until cheese is melted and chicken is no longer pink in the center, about 30 minutes.
