Ingredients You’ll Need

Ingredients for chicken bacon ranch casserole recipe.
  • Bacon: You can cook the bacon in the oven or make air fryer bacon.
  • Penne Pasta: I used whole wheat penne to sneak in some extra fiber and nutrition. Regular penne can also be used.
  • Broccoli: You’ll need one pound of fresh broccoli, chopped into bite-sized florets.
  • Butter and Olive Oil: For sautéing the onion and also to create the base of the creamy sauce. I use a combination of both butter and olive oil for a balance of richness and flavors.
  • Onion and Garlic: These aromatic ingredients add lots of flavor.
  • Flour: All-purpose flour thickens the sauce.
  • Chicken Broth and Milk: For the base of the creamy sauce. Whole milk provides richness and chicken broth keeps the sauce from being too heavy.
  • Seasonings: The ranch seasoning is a combination of garlic powder, onion powder, dried dill, salt and pepper. Paired with fresh chives, it adds the best flavor to this chicken bacon ranch casserole.
  • Cooked Chicken Breast: You can shred or chop the chicken for the casserole. Rotisserie chicken works well and helps to cut down on prep time. You can also use leftover cooked chicken, Poached Chicken, Instant Pot Shredded Chicken or Crockpot Shredded Chicken.
  • Cheddar Cheese: I recommend sharp cheddar cheese for the most flavor.
  • Fresh Chives: To garnish the casserole when serving. The fresh chives really bring out the ranch flavors in the casserole.

Instructions
 

Cook the Bacon

  • Preheat oven to 400° F. Line a rimmed baking sheet with foil, and fold the edges of the foil up a bit to contain the bacon grease.
  • Lay the bacon slices in a single layer on the foil. Bake for 12-20 minutes, until cooked through.
  • Transfer bacon to a paper towel-lined plate to soak up excess grease. Then chop the bacon. Set aside.

Prepare the Casserole

  • Reduce oven temperature to 350° F.
  • Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions for al dente, adding the broccoli florets to the pot during the last 1-2 minutes of the cook time. Drain the pasta and broccoli into a colander, rinse under cold water, drain. Put the cooked pasta and broccoli back into the empty cooking pot. Set aside.
  • Heat the butter and olive oil in a large skillet over medium heat. Add the onion and cook until softened, about 3 minutes.
  • Add the garlic and flour and cook for 30 seconds, stirring.
  • Stir in the chicken broth, milk, garlic powder, onion powder, dried dill, salt and pepper. Cook, stirring often, until the mixture just comes to a simmer and thickens slightly. Remove pan from the heat.
  • To the pot with the pasta and broccoli, add the shredded cooked chicken, half of the shredded cheese, ⅔ of the chopped cooked bacon and the sauce from the skillet. Stir to combine and then transfer the mixture to a 13×9-inch baking dish.
  • Top casserole with the remaining shredded cheese and remaining chopped bacon. Cover with foil (spray the underside of the foil with cooking spray to help prevent the cheese from sticking to it). Bake, covered, for 20 minutes. Then uncover and bake 5-10 minutes more, until cheese is melted and casserole is hot throughout.
  • Serve with chopped fresh chives.
