Mashed Potato Casserole Ingredients
For the Casserole
• Russet Potatoes – Creamy base; use for their fluffy texture when mashed—Yukon Gold potatoes can be substituted for a buttery flavor.
• Salt – Enhances flavor during potato boiling; kosher salt is recommended for best results.
• Butter – Adds richness and creaminess; opt for full-fat for optimal texture—margarine can be used as a dairy-free alternative.
• Sour Cream – Contributes tanginess and creaminess; Greek yogurt offers a lighter, protein-rich option.
• Warm Milk – Ensures a smooth consistency; whole milk is recommended for creaminess, while almond milk can work for a dairy-free version.
• Cheddar Cheese (1 ½ cups + ½ cup) – Provides a cheesy flavor and creamy texture; sharp cheddar is best for depth—Gruyère can be a delicious alternative.
• Fresh Chives – Adds freshness and color; omit or substitute with green onions for simplicity.
• Black Pepper & Garlic Powder – Seasoning for depth; adjust to taste for a personalized flavor.
For the Topping
• Panko Breadcrumbs – Creates a crunchy topping; perfect for added texture—regular breadcrumbs can substitute if needed.

Step‑by‑Step Instructions for Ultimate Creamy Cheesy Mashed Potato Casserole
Step 1: Prepare Potatoes
Begin by peeling and quartering your russet potatoes. Place them in a large pot filled with cold, salted water. Bring the pot to a boil over medium-high heat, then reduce to a simmer for about 15-20 minutes, or until the potatoes are fork-tender. Once cooked, drain the potatoes and allow them to steam dry for a few minutes.
Step 2: Mash Potatoes
Return the drained potatoes to the pot and use a potato ricer or masher to create a smooth texture. It’s important not to use a food processor, as it can make the potatoes gummy. Aim for a fluffy consistency, ensuring that no lumps remain. This smooth base will be the heart of your Mashed Potato Casserole.
Step 3: Mix Ingredients
To the smooth potatoes, add in the softened butter, sour cream, and warm milk. Stir the mixture until it’s completely creamy. Next, fold in the sharp cheddar cheese, finely chopped chives, salt, black pepper, and garlic powder. Taste the mixture to adjust seasoning, ensuring it’s packed with flavor before moving on.
Step 4: Preheat Oven
While you mix the mashed potato ingredients, preheat your oven to 375°F (190°C). Meanwhile, lightly grease a 9×13 inch baking dish with butter or cooking spray. This will prepare the dish for the layered masterpiece of your creamy cheesy mashed potato casserole.
Step 5: Transfer Mixture
Carefully spread the creamy potato mixture evenly into the prepared baking dish. Use a spatula to smooth the top, ensuring that it’s level. This even surface will help the casserole cook uniformly and create a lovely golden crust on top.
Step 6: Prepare Topping
In a mixing bowl, combine the panko breadcrumbs with crumbled bacon and melted butter. Toss everything together until the breadcrumbs are well-coated. This crunchy topping will add delightful texture to the casserole. Once mixed, sprinkle this topping generously over the surface of the mashed potato mixture, followed by the remaining cheddar cheese.
Step 7: Bake Casserole
Place the dish in the preheated oven and bake for 35-40 minutes. The casserole is ready when the edges are bubbly and the topping is golden brown. If you notice the top browning too quickly, gently tent it with foil to prevent burning while the inside continues to bake.
Step 8: Rest & Garnish
Once baked, allow the casserole to rest for about 5-10 minutes before serving. This resting period helps set the layers for easier serving. Before you dig in, consider garnishing the top with extra chopped chives to add a fresh pop of color and flavor to your Ultimate Creamy Cheesy Mashed Potato Casserole.
