Why You’ll Love This Recipe

This easy loaded mashed potato casserole is a must-try because it combines comfort with flavor and convenience. It’s rich, creamy, and topped with melted cheese and crispy bacon that adds both texture and taste. Perfect for busy weekdays, it’s also a reliable crowd-pleaser for parties and potlucks. With minimal prep time and simple ingredients, this dish is both practical and satisfying.

Ingredients Notes

For the best results, use Yukon gold potatoes for a naturally buttery flavor. You’ll need crisp bacon for a savory crunch, shredded cheddar cheese for that gooey richness, and a dollop of sour cream to achieve the perfect creamy consistency. If you’re short on cheddar, mozzarella makes a fine substitute. For a healthful twist, add chopped green onions or steamed broccoli for extra vitamins and color.

Recipe Steps

Step 1

Begin by preheating your oven to 375°F (190°C). While the oven is warming up, peel and chop the potatoes into evenly sized chunks to ensure even cooking.

Step 2

Boil the potatoes in a large pot of salted water for about 15-20 minutes, or until they are tender. Drain thoroughly to remove excess water.

Step 3

Mash the potatoes with butter, sour cream, and some milk until smooth. Be sure not to over-mash, as this can lead to a gluey texture. Season with salt and pepper.

Step 4

Spread the mashed potatoes in a buttered baking dish, evenly sprinkle the shredded cheese over the top, and layer with crumbled bacon pieces.

Step 5

Bake the casserole in the preheated oven for 20-25 minutes or until the cheese is bubbling and starting to brown. Let it cool slightly before serving.

Storage Options

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. For freezing, portion out the casserole and wrap securely in foil and place them in a freezer-safe bag for up to 1 month. Reheat in the oven at 350°F until warmed through.

Variations & Substitutions

This dish can easily be modified to suit dietary needs. For a vegetarian version, omit the bacon and add roasted vegetables like bell peppers or asparagus. For a lower-carb alternative, swap out the potatoes for cauliflower while maintaining the same creamy, cheesy topping.

Serving Suggestions

This casserole is versatile and pairs beautifully with roasted chicken or as a standalone main dish accompanied by a fresh green salad. It makes an excellent side for holiday feasts or a cozy winter meal enjoyed by the fireplace.

Frequently Asked Questions

Can I prepare this casserole in advance? Yes, you can prepare the mashed potato mixture a day ahead and refrigerate it. Assemble and bake the following day, adding 10 more minutes to the baking time for best results.

What can I use instead of sour cream? Greek yogurt is a healthy substitute for sour cream and provides a similar tangy flavor while keeping the dish creamy.

Can I make this dairy-free? Absolutely! Substitute the milk, sour cream, and cheese with plant-based alternatives, like almond milk, coconut yogurt, and dairy-free cheese, respectively.
