Ingredients

  • 8 oz dry rotini pasta
  • 3 tbsp butter
  • 1 1/2 tsp minced garlic
  • 1/4 cup flour
  • freshly ground black pepper, to taste
  • 2 cups half & half (or whole milk)
  • 1 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1/4 cup shredded Parmesan cheese
  • 2-3 cups chopped rotisserie chicken

Instructions

  • Spray an 11x7" casserole dish with non stick cooking spray, and set aside. 
  • Cook the pasta according to the package instructions. Drain, run under cold water to stop cooking, and set aside.
  • In a large skillet, over medium heat, melt the butter. Stir in the garlic cooking just until fragrant, about 30-45 seconds. Don't over cook and let the garlic burn or turn bitter.
  • Whisk in the flour and pepper until smooth, and cook until the mixture's bubbling. Whisk in the half & half, a little at a time, until completely incorporated and simmer until the sauce is smooth and slightly thickened. Remove the skillet from heat.
  • Stir in 3/4 cups of both the cheddar and mozzarella cheeses, and the Parmesan cheese, whisking until completely melted and the cheese sauce is smooth. 
  • Add the pasta & chicken to the sauce, stirring gently until everything's evenly combined and generously coated in the cheese sauce.
  • Spread the mixture out evenly into the prepared casserole dish. Sprinkle the remaining cheese evenly out overtop. You can be a little generous and add a bit extra for added cheese effect. 
  • Bake the dish at 350 degrees for 25-30 minutes, or until the dish's bubbly throughout and the cheeses are melted and golden brown at the edges. Let rest for 2-3 minutes before scooping and serving.

Notes

  • Be careful not to overcook the garlic. If it burns, it will get bitter.
  • Want to add some veggie action into the mix? Add some steamed broccoli. Peas & carrots also work. You could even use diced tomatoes & green chiles for a Tex Mex spin.
  • Add extra cheese on top for a real cheesy treat!
