  • 4 tbsp butter, divided
  • 5-6 button mushrooms, sliced
  • 1/2 yellow onion, diced
  • 1 large clove of garlic, minced
  • Sea salt and freshly cracked pepper, to taste
  • 1 cup chicken broth
  • 1 cup milk
  • 1 cup sour cream
  • 4 oz cream cheese
  • 3 cups leftover roasted chicken, chopped
  • 1 tbsp poppy seeds
  • 1/4 cup Parmesan cheese, grated

Ritz Topping:

  • 1 sleeve of Ritz crackers, crushed
  • 2 tbsp butter, melted


  • Preheat the oven to 375 degrees. 
  • Heat 1 tablespoon of butter in a large cast iron skillet over medium-high heat. Add the mushrooms and onion then cook, stirring occasionally, for 5-7 minutes, or until the mushrooms are golden brown and the onion is softened. 
  • Add the minced garlic and cook, stirring constantly, for 1 minute. Season with sea salt and freshly cracked pepper, to taste. Remove the mushroom mixture from the skillet onto a plate; set aside.
  • Heat the remaining 3 tablespoons of butter in the same cast iron skillet over medium-high heat. 
  • Add the flour and cook, whisking constantly, for 3 minutes. 
  • Slowly add the chicken broth and milk while constantly whisking. 
  • Add the sour cream and cream cheese then simmer, stirring often, for 7-10 minutes, or until the cream cheese is melted and the sauce has thickened. 
  • Add the chicken, mushroom mixture, and poppy seeds to the sauce and stir until combined. Taste and season with a bit of sea salt and lots of cracked pepper, to taste. 
  • Make the topping by combining the crushed sleeve of Ritz crackers and the melted butter together in a bowl; mix until well combined.
  • Sprinkle the top of the casserole evenly with the parmesan cheese followed by the crushed Ritz topping. 
  • Place into the oven and bake for 15-20 minutes, or until casserole is bubbling and the topping is golden brown. 
  • Remove from the oven and allow to cool for a few minutes. Top with fresh parsley and serve. Enjoy.
