  • 1 tablespoon ranch seasoning mix (see notes for homemade option)

  3. Add in the pasta, chicken, peas and carrots, green onions and cheese and stir until everything is evenly coated and mixed together. Add salt and pepper to taste
  4. Transfer the chicken mixture into the greased casserole dish. Gently flatten into an even layer. Add a sprinkle of cheese to the top if you want extra, and then top with the fried onions
  5. Cover the casserole and bake for 30 to 35 minutes, until sides are bubbling


  • Milk of choice can be used in place of evaporated milk, but it won’t be as creamy
  • You can add up to another 1 cup cheese if you’d like it cheesier
  • 6 slices cooked and chopped bacon can be added in during step 3
  • To make your own ranch seasoning: Combine 1 and 1/2 teaspoon dried dill, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, and a pinch of salt and pepper
