Cook pasta according to package instructions; drain and set aside.
Prepare a portion of pan-seared chicken breast and remove it from the pan. Slice the chicken into thin strands or cube and cover to keep warm.
In the same skillet, melt butter and sauté minced garlic until fragrant.
Whisk in the cream, milk, and flour into the butter.
Gradually stir in grated parmesan cheese until smooth—season with salt, pepper, and ranch powder. Cook until the sauce thickens.
Combine pasta, sliced chicken, cooked bacon, alfredo sauce, and ¾ cup of cheese in a casserole dish. Top the dish with the remaining shredded cheese.
Bake at 375°F for 10-15 minutes until warm and cheese is melted.
Garnish with grated parmesan cheese and parsley.
Serve and enjoy, friends!
