Ingredient Info and Substitution Suggestions

CHICKEN – You will need about 4 breasts, or 2 pounds of cooked chicken for this recipe. This recipe is excellent for using up leftovers, but you can also opt for a pre-cooked rotisserie chicken or cook up the breasts yourself before beginning. Feel free to slice the chicken if preferred.

CHEESE – Instead of using provolone or pepper jack cheese, experiment with different cheeses like mozzarella or gouda.

CREAM CHEESE – Cream cheese is the base for the rich and creamy sauce. Be sure to soften it before beginning for the best texture. To do so, cube the cream cheese and allow it to rest at room temperature for around 30 minutes.

3. Reduce heat to medium and add in the garlic, onion powder, sea salt, and ground pepper and cook until fragrant.
4. Place the cream cheese and the heavy cream into the skillet and stir consistently until the cream cheese has fully melted. Bring to a simmer, then reduce the heat to low. Add in pepper jack cheese, stirring until melted. Remove from heat.
5. Mix the shredded chicken into the skillet and fully combine before transferring into the prepared 9×13 dish.
6. Top with provolone cheese slices and bake for 15 minutes. The cheese should be fully melted on top and starting to become golden brown. If needed, broil for a minute or two.
7. Garnish with freshly chopped parsley.
