Step 3: Combine Potatoes and Cheese
- Preheat your oven to 375°F (190°C).
- In a large mixing bowl, combine the cooked potatoes, creamy sauce, chopped onion, bell pepper, and 2 cups of shredded cheese. Mix gently until everything is evenly coated.
Step 4: Prepare the Topping
- In a small bowl, mix breadcrumbs with melted butter and 1/4 cup of cheese.
- This will create a crunchy, golden topping that contrasts beautifully with the creamy potatoes.
Step 5: Assemble the Casserole
- Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
- Pour the potato and cheese mixture into the dish, spreading it evenly.
- Sprinkle the breadcrumb topping over the casserole.
Step 6: Bake to Perfection
- Bake uncovered in the preheated oven for 25–30 minutes.
- The casserole is done when the topping is golden brown and the cheese inside is bubbly.
- Let it cool for 5 minutes before serving to allow it to set slightly.
Step 7: Serve and Enjoy
- Serve hot as a side dish for meats, like roasted chicken or ham, or enjoy it as a hearty vegetarian main dish.
- Garnish with chopped fresh parsley for a touch of color and freshness.
Tips for Success
- Cheese Variety: Mix cheddar, mozzarella, or Gruyère for a richer flavor.
- Add-ins: Crispy bacon, green onions, or sautéed mushrooms can make it even more indulgent.
- Make Ahead: Assemble the casserole in advance and refrigerate. Bake right before serving.
