Steps to Create Your Loaded Baked Potato Casserole

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray. I always use butter for that extra richness, just like my Nonna Rosa taught me.
2. Bring a large pot of salted water to a boil. Add the diced potatoes and cook until tender, about 15 minutes. They should be fork-tender but not falling apart.
3. Drain the potatoes well and return them to the warm pot. Mash them with the melted butter, sour cream, and milk until smooth and creamy. If you like a little texture, leave some small lumps—this reminds me of the rustic mashed potatoes my mom would make.
4. Season the mashed potatoes with garlic powder, onion powder, 1/2 teaspoon salt, and black pepper. Taste and adjust seasoning as needed; seasoning is key in bringing out the flavors.
5. Fold in 1 cup of shredded cheddar cheese, the white parts of the green onions, and half of the crumbled bacon. This mix is where the magic starts to take shape.
6. Transfer the potato mixture to the prepared baking dish, smoothing the top with a spatula.
7. Sprinkle the remaining cheddar cheese evenly over the top, followed by the remaining bacon crumbles. This final layer will crisp up beautifully in the oven.
8. Bake uncovered for 20-25 minutes, or until the cheese is melted and bubbly, and the edges start to turn golden brown.
9. Remove from the oven and let it cool for 5 minutes before serving. Garnish with the green parts of the sliced green onions for a fresh pop of color and flavor.

Tips for Making the Best Loaded Baked Potato Casserole

One of my fondest memories is standing on a flour-dusted stool in my grandmother’s kitchen, watching her adjust seasonings with a practiced hand. That lesson still guides me today: always taste and tweak as you go. Here are a few tips to make this casserole sing at your table: Learn more: Mastering Homemade Pasta: The Ultimate KitchenAid Recipe Guide

• Don’t overcook the potatoes. You want them tender but still holding their shape so the casserole has a nice texture.
• Use real butter. It adds a richness that margarine or oil just can’t match, and it’s a nod to traditional cooking like my mom and Nonna Rosa always insisted on.
• Cook bacon until crispy. Crispy bacon adds texture contrast that’s essential in this dish. Save some of the bacon fat to sauté the green onions if you want an extra flavor boost.
• Experiment with cheeses. While sharp cheddar is classic, mixing in a bit of smoked gouda or Monterey Jack can add depth that reminds me of my time in Spanish kitchens.
• Make it ahead. You can prepare the casserole a day in advance, then bake it just before serving. It’s perfect for busy family dinners or holiday feasts.

Serving Suggestions and Pairings

This Loaded Baked Potato Casserole is hearty enough to shine on its own, but I love pairing it with simple, fresh sides to balance the richness. Growing up, my family always had a green salad with a tangy vinaigrette alongside heavier dishes—something I still do today.

• A crisp mixed green salad with lemon vinaigrette
• Steamed or roasted seasonal vegetables like asparagus or green beans
• Grilled chicken or pork chops for added protein
• For a festive touch, serve with a bright beet and arugula salad, a nod to the garden-fresh flavors Nonna Rosa cherished

And don’t forget a chilled glass of white wine or sparkling water with a slice of lemon to refresh the palate.

Storage and Reheating Tips

Like many dishes rooted in family tradition, this casserole tastes just as good the next day—sometimes even better once the flavors have melded overnight. Here’s how to keep it fresh and delicious:

• Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheat individual portions in the microwave, covered, for 1-2 minutes until warmed through.
• For best texture, reheat a larger portion in a 350°F oven for 10-15 minutes to bring back the crispy cheese topping.
• If freezing, wrap tightly in foil or plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
