Ingredients
-
2 large boneless, skinless chicken breasts (cubed)
-
3 cups of diced potatoes (preferably Yukon Gold or Russet)
-
2 cups broccoli florets (fresh or frozen)
-
1 cup shredded cheddar cheese (or mozzarella, for a milder flavor)
-
1 cup heavy cream (or half-and-half)
-
1/2 cup sour cream (optional, for added richness)
-
2 cloves garlic (minced)
-
1 teaspoon onion powder
-
1 teaspoon paprika
-
Salt and pepper to taste
-
2 tablespoons olive oil
-
1 tablespoon chopped parsley (for garnish)
Instructions
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a large casserole dish or a 9×13-inch baking pan.
Step 2: Cook the Chicken
In a skillet over medium heat, add a tablespoon of olive oil. Add the cubed chicken, season with salt, pepper, garlic, and onion powder. Cook for 5–7 minutes until browned but not fully cooked through (it will finish baking in the oven).
Step 3: Prepare the Potatoes
Wash and dice the potatoes into bite-sized chunks. Toss them in a bowl with a tablespoon of olive oil, paprika, salt, and pepper. Roast them separately in the oven for 15 minutes for extra crispiness or simply mix them raw into the casserole for a softer texture.
Step 4: Combine and Assemble
In a large mixing bowl, combine the partially cooked chicken, roasted (or raw) potatoes, broccoli florets, sour cream, and half of the shredded cheese. Pour in the heavy cream and mix everything together gently.
Transfer the mixture into the casserole dish. Top with the remaining cheese.
Step 5: Bake
Cover with foil and bake for 30 minutes. Then remove the foil and bake uncovered for an additional 10–15 minutes or until the top is golden and bubbling.
Step 6: Garnish and Serve
Remove from oven and let it rest for 5 minutes. Garnish with chopped parsley before serving.
