Equipment

  • Large pot (for boiling pasta)
  • Medium saucepan (for sauce)
  • Colander
  • Whisk
  • Spatula
  • Mixing bowls
  • 9x13-inch baking dish
  • Aluminum foil (optional)
  • Oven mitts

Ingredients
  

  • Pasta & Base:
  • 12 oz rotini pasta uncooked
  • 2 cups cooked chicken shredded or diced
  • 6 strips cooked bacon chopped
  • 1 cup steamed or sautéed vegetables optional: broccoli, mushrooms, spinach
  • Creamy Ranch Sauce:
  • 2 tablespoons butter
  • 8 oz cream cheese softened
  • 1 packet 1 oz ranch seasoning mix
  • 1/2 cup milk or heavy cream
  • 1/4 cup sour cream or Greek yogurt optional
  • Salt and black pepper to taste
  • Cheese:
  • 1 ½ cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1/4 cup shredded Parmesan cheese for topping

Instructions
 

  • Cook the pasta: Bring a large pot of salted water to a boil. Cook rotini according to package instructions until al dente. Drain and set aside.
  • Prepare the sauce: In a saucepan over medium heat, melt butter. Add cream cheese, ranch seasoning, and milk. Whisk until smooth. Stir in sour cream (if using) and 1 cup of the shredded cheese. Mix until melted and smooth.
  • Combine the ingredients: In a large bowl, combine pasta, chicken, bacon (reserve some for topping), veggies (if using), and ranch cheese sauce. Mix well.
  • Assemble the bake: Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. Pour the mixture into the dish and spread evenly. Top with remaining cheddar, mozzarella, Parmesan, and reserved bacon.
  • Bake: Place uncovered in the oven for 20–25 minutes, until cheese is bubbly and golden. For a crispier top, broil for the last 2–3 minutes.
  • Serve: Let rest for 5 minutes before serving. Garnish with chopped green onions or parsley if desired.

Notes

Use rotisserie chicken for a shortcut.
To make vegetarian: omit chicken and bacon, and add extra veggies or plant-based protein.
To freeze: assemble but don’t bake. Wrap tightly and freeze for up to 3 months. Thaw overnight before baking.
To reheat: add a splash of milk and microwave or oven-reheat covered.
