Ingredients
- 1.5 lbs chicken breasts, cut into bite-sized pieces
- 4 medium potatoes, peeled and cubed
- 3 cups broccoli florets
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 cup heavy cream
- 1/2 cup chicken broth
- 2 tablespoons butter
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- 1/2 teaspoon paprika
- Salt and black pepper to taste
- 1 tablespoon olive oil
Step-by-Step Instructions
Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with olive oil or butter.
Step 2: In a large bowl, toss the cubed potatoes with olive oil, salt, pepper, and paprika. Spread them evenly in the prepared baking dish and bake for 15 minutes to start softening.
Step 3: While potatoes bake, season the chicken pieces with Italian seasoning, garlic, salt, and pepper. In a skillet, melt butter over medium heat and cook the chicken until lightly browned but not fully cooked (about 5-6 minutes).
Step 4: Remove potatoes from oven and scatter the broccoli florets over them. Arrange the browned chicken pieces evenly throughout the dish.
Step 5: In a separate bowl, whisk together heavy cream and chicken broth. Pour this mixture evenly over the casserole ingredients.
Step 6: Combine all three cheeses in a bowl, then sprinkle generously over the entire casserole, covering everything evenly.
Step 7: Return the casserole to the oven and bake for 25-30 minutes, or until the cheese is golden and bubbly, and the potatoes are fork-tender.
Step 8: Let the casserole rest for 5 minutes before serving to allow the sauce to thicken slightly.

Expert Tips
• Cut potatoes evenly: Make sure all potato cubes are roughly the same size so they cook evenly.
• Don’t overcook broccoli: The broccoli will continue cooking in the oven, so it should be crisp-tender going in.
• Customize the cheese: Feel free to mix up the cheese combinations – Colby Jack, Gouda, or pepper jack work great too.
• Make ahead option: Assemble the casserole up to the baking step, cover, and refrigerate overnight. Add 5-10 minutes to baking time.
