Ingredients Method Notes

Ingredients
  

  • Ingredients
  • 2 cups pre-cooked chicken pulled or finely chopped
  • 1 cup your favorite marinara sauce
  • 1 cup creamy ricotta
  • 1 cup shredded mozzarella
  • ½ cup finely grated Parmesan
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • Salt and black pepper as needed
  • 1 cup whole wheat breadcrumbs

Method
 

Step 1: Heat the Oven

Set your oven to 375°F (190°C) so it’s fully preheated and ready to go once your casserole is assembled.

    Step 2: Mix the Filling

    In a large bowl, combine the shredded chicken, marinara sauce, ricotta, dried basil, oregano, salt, and pepper. Stir thoroughly until the mixture looks creamy and evenly seasoned.

      Step 3: Create the First Layer

      Lightly grease a 9×13-inch baking dish. Spread half of the chicken mixture evenly across the bottom.

        Step 4: Add Cheese Layer

        Sprinkle half of the mozzarella and half of the Parmesan over the chicken layer to build that rich, cheesy base.

          Step 5: Repeat the Layers

          Spread the remaining chicken mixture over the cheese. Finish by topping it with the rest of the mozzarella and Parmesan.

            Step 6: Add the Crunch

            Scatter the whole wheat breadcrumbs evenly across the top to create a golden, crispy finish.

              Step 7: Bake

              Place the casserole in the oven and bake for 25–30 minutes, or until the cheese melts completely and the top turns golden brown and bubbly.

                Step 8: Rest Before Serving

                Remove from the oven and allow it to cool for about 5 minutes. This helps the layers set and makes slicing easier.

                  Notes

                  Serving Suggestion

                  Bring this casserole straight to the table while it’s hot and bubbly. Pair it with a fresh green salad or roasted vegetables to lighten things up. For extra flavor, spoon a little warm marinara over each portion just before serving.

                  Helpful Tips

                  • Prep in Advance: Assemble everything the day before, cover tightly, and refrigerate. Bake when ready to serve.
                  • Cheese Flexibility: Swap in provolone, part-skim mozzarella, or any good melting cheese you have on hand.
                  • Boost the Nutrition: Mix in chopped spinach, zucchini, or mushrooms for added texture and nutrients.

                  Variations

                  • Add sautéed spinach or roasted red peppers for extra flavor.
                  • Replace chicken with seasoned tofu or chickpeas for a plant-based version.
