Ingredients:
- 2 Tbsp Unsalted Butter
- 1 box (6.8 oz) Chicken Rice-a-Roni Mix (including rice, vermicelli, and seasoning packet)
- 2 cups low-sodium Water or Chicken Stock
- 3 Tbsp Unsalted Butter
- 1/2 cup finely diced Yellow Onion
- 1/2 cup finely diced Celery
- 3 Tbsp All-Purpose Flour
- 1 cup low-sodium Chicken Stock
- 1 cup Whole Milk or Half-and-Half
- 1/2 tsp Dried Thyme (Optional)
- 3 cups cooked, shredded or diced Chicken
- 1 cup shredded Sharp Cheddar Cheese
- 1/2 cup shredded Monterey Jack or Mozzarella
- 1/4 cup Panko Breadcrumbs (optional)
Instructions:
- Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch casserole dish. Shred or dice the cooked chicken and dice the onion and celery.
- Melt 2 Tbsp of butter in a large skillet over medium heat. Add the Rice-a-Roni rice and vermicelli mixture (reserve the seasoning packet). Sauté for 3–5 minutes until the pasta is golden brown and smells slightly nutty.
- Add the 2 cups of water/stock and the Rice-a-Roni seasoning packet to the skillet. Bring to a boil, reduce heat, cover, and simmer for 5 minutes only (the rice must remain slightly al dente). Remove from heat and set aside.
- In the same skillet, melt the remaining 3 Tbsp of butter over medium heat. Add the diced onion and celery. Sauté gently for 5–7 minutes until softened and translucent.
- Sprinkle the 3 Tbsp of flour over the cooked vegetables. Stir continuously for 1 minute to cook off the raw flour taste (creating the roux).
- Slowly whisk in the 1 cup of chicken stock until smooth. Then, slowly whisk in the 1 cup of milk/half-and-half. Bring the sauce to a gentle simmer, stirring frequently, until it thickens sufficiently to coat the back of a spoon (about 3–4 minutes). Season with dried thyme, and check for salt.
- Remove the sauce from the heat. Gently stir in the 3 cups of shredded chicken and half (3/4 cup) of the total shredded cheese mixture (Cheddar and Monterey Jack).
- Gently fold the partially cooked Rice-a-Roni base into the creamy chicken mixture until evenly distributed. Pour the entire mixture into the prepared casserole dish.
- Sprinkle the remaining cheese evenly over the top. If using, sprinkle the Panko breadcrumbs over the cheese.
- Bake for 20–25 minutes, or until the casserole is bubbly around the edges, piping hot throughout, and the cheese topping is golden brown.
- Allow the casserole to rest on the counter for 5–10 minutes before serving to let the sauce set up.
