Ingredients You’ll Need

• 2 lbs boneless, skinless chicken breasts, cubed
• 4 medium potatoes, peeled and diced
• 3 cups broccoli florets
• 1 cup shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• 1 cup heavy cream
• 1/2 cup sour cream
• 1/4 cup butter
• 1 medium onion, diced
• 3 cloves garlic, minced
• 2 tbsp all-purpose flour
• 1 tsp paprika
• 1 tsp dried thyme
• Salt and pepper to taste

Step-by-Step Instructions

Start by preheating your oven to 375°F (190°C). This ensures your casserole will cook evenly and develop that beautiful golden-brown crust we all love.

Step 1: Cook the chicken and vegetables. In a large skillet, melt butter over medium heat. Add diced onion and cook until softened, about 3-4 minutes. Add garlic and cook for another minute until fragrant. Add chicken cubes and cook until no longer pink, approximately 5-7 minutes.

Step 2: Prepare the creamy sauce. Sprinkle flour over the chicken mixture and stir to coat. Gradually add heavy cream while stirring constantly. Bring to a gentle simmer until the sauce thickens slightly. Stir in sour cream, paprika, thyme, salt, and pepper.

Step 3: Combine everything. Add diced potatoes and broccoli florets to the skillet, stirring to coat everything in the creamy sauce. Transfer the mixture to a 9×13 inch baking dish. If you love creamy one-pan dinners, you’ll appreciate how simple this comes together!

Step 4: Add the cheese. Sprinkle both cheddar and mozzarella cheeses evenly over the top of the casserole. This creates that irresistible cheesy crust that makes this dish so delightful.

Step 5: Bake to perfection. Cover with foil and bake for 30 minutes. Remove foil and bake for another 15-20 minutes, or until potatoes are tender and cheese is golden brown. Let it rest for 5 minutes before serving.
