How to Make Loaded Mashed Potato Casserole Recipe
Step 1: Boil the Potatoes
Start by preheating your oven to 375˚F—this ensures your casserole will start baking right after prepping. Place your peeled and cubed potatoes into a pot, cover them completely with water, and bring it to a boil over medium-high heat. Once boiling, lower the heat to medium and add 1 teaspoon of salt. This step not only cooks the potatoes through but seasons them perfectly for that irresistible base flavor.
Step 2: Prepare the Butter and Milk Mixture
While the potatoes cook, melt the butter in a small saucepan with milk until the butter is completely liquified. Keep the mixture warm on the stove by turning off the heat but not removing the pan. To this, whisk in the sour cream until smooth—that creamy tang will make your casserole stand out.
Step 3: Mash the Potatoes
Drain the boiled potatoes and return them to the pot or a large mixing bowl. At this point, mash them with your preferred method—whether by hand or a mixer—until creamy and smooth. Pour in the warm butter-milk-sour cream blend and mix until everything comes together into a perfect fluffy mound of potato goodness.
Step 4: Cook the Bacon and Assemble
In a skillet over medium heat, sauté the chopped bacon until it reaches a golden brown crispness. This is crucial, as bacon fat adds incredible flavor but too soft bacon can make the casserole soggy. Spread the creamy mashed potatoes evenly into a baking dish, sprinkle the crispy bacon on top, and then generously scatter the shredded Colby Jack cheese over everything.
Step 5: Bake to Perfection
Cover the dish with foil and bake for 25 minutes at 375˚F. This allows the flavors to meld and the potatoes to heat through thoroughly. Remove the foil and bake uncovered for another 10 minutes, so the cheese melts beautifully and develops those irresistible golden spots that make casseroles so inviting.
How to Serve Loaded Mashed Potato Casserole Recipe
Garnishes
Finishing your casserole with fresh green onions or chives not only adds a delightful color contrast but also injects a fresh, mild onion flavor that lightens the richness. A sprinkle of freshly cracked black pepper can also elevate the flavors just before serving.
Side Dishes
This Loaded Mashed Potato Casserole Recipe pairs wonderfully with roasted vegetables, grilled chicken, or slow-cooked brisket. Its creamy, cheesy nature balances beautifully against vibrant greens or crisp, acidic salads for a well-rounded meal.
Creative Ways to Present
For a fun twist at your next dinner, serve the casserole in individual ramekins for single servings. You can also layer it with caramelized onions or add a hint of garlic in the mash for an extra flavor kick. A drizzle of sour cream or a scattering of fresh herbs right before serving makes it look as amazing as it tastes.
Make Ahead and Storage
Storing Leftovers
After enjoying your casserole, store leftovers in an airtight container placed in the refrigerator. It will keep well for up to 3 days, maintaining its creamy texture and flavor. Just make sure to cool it completely before covering to avoid condensation.
Freezing
You can freeze this casserole if you want to prep in advance. Allow it to cool fully, then wrap it tightly in plastic wrap and aluminum foil or place it in a freezer-safe container. The casserole stays good frozen for up to 2 months. When you’re ready to enjoy it, thaw overnight in the refrigerator.
Reheating
Reheat leftovers in the oven at 350˚F until warmed through and the cheese has melted again—usually about 20 minutes. You can also microwave individual portions, but covering loosely with a damp paper towel helps keep the potatoes from drying out.
FAQs
Can I use a different type of potato for this recipe?
Russet potatoes are best for this casserole due to their starchy nature, which makes the mash creamy and fluffy. However, Yukon Gold potatoes can also work if you prefer a slightly buttery texture and a richer taste.
Is it possible to make this recipe vegetarian?
Absolutely! Simply omit the bacon or substitute it with smoked tempeh or a plant-based bacon alternative. The cheese and sour cream will still deliver plenty of flavor and creaminess.
Can I add other toppings besides bacon and cheese?
Definitely! Feel free to get creative by adding sautéed mushrooms, caramelized onions, or even chopped jalapeños for some heat. Just keep the classic base intact for that perfect “loaded” experience.
How do I make the casserole less rich or lighter?
Use reduced-fat milk and cheese, and swap sour cream for Greek yogurt. You might also reduce the butter a little. These changes lighten the dish without compromising too much on flavor.
What’s the best baking dish size for this recipe?
A medium-sized 8×8-inch or similar casserole dish works great—large enough to spread the potatoes evenly but not so large that the casserole dries out during baking.
