Ingredients
These simple ingredients create a rich, layered casserole with bold flavor and satisfying texture.
1.5 lbs chicken breast, cubed
3 medium potatoes, cubed
1 large eggplant, cubed
1 green bell pepper, diced
2 cups tomato sauce
1.5 cups white cream sauce
2 cups shredded mozzarella cheese
2 tbsp olive oil
Fresh parsley for garnish
You can swap mozzarella for a cheddar-mozzarella mix for extra sharpness. Greek yogurt thinned with a little milk works as a lighter white sauce alternative. Turkey or leftover rotisserie chicken also substitutes well for the fresh chicken breast.
Follow these clear steps to build a golden, cheesy casserole that comes out perfect every time.
Step 1: Roast the vegetables
Toss cubed potatoes and eggplant with olive oil, salt, and pepper. Spread on a baking sheet and roast at 400°F until golden and tender, about 25 minutes.
Step 2: Cook the chicken
Heat a skillet over medium-high heat and cook the cubed chicken until lightly browned. Add diced green bell pepper and cook until softened.
Step 3: Add tomato sauce
Pour the tomato sauce into the skillet with the chicken and peppers. Simmer for a few minutes so the flavors blend and the sauce thickens slightly.
Step 4: Prepare the baking dish
Place the roasted potatoes and eggplant in an even layer in a greased glass baking dish. Spread them out so they form a solid base.
Step 5: Layer the chicken mixture
Spoon the chicken and tomato sauce mixture evenly over the roasted vegetables. Make sure every corner gets some of the saucy chicken.
Step 6: Add the cream sauce
Pour the white cream sauce over the chicken layer in a steady stream. Gently spread it so it covers most of the surface without mixing too much.
Step 7: Top with cheese
Sprinkle the shredded mozzarella evenly across the top. Use the full amount for that signature golden, stretchy cheese pull.
