Ingredients
To create this delicious Loaded Mashed Potato Casserole, gather the following ingredients:
For the Casserole
- 2 ½ lbs russet potatoes (peeled and cut into 1/2 cubes)
- 1 tsp salt (or to taste)
- 3/4 cup milk (whole or 2% milk)
- 8 Tbsp unsalted butter
- ¼ cup sour cream
- 8 oz Colby Jack cheese (freshly shredded)
For Topping
- 8 oz turkey bacon (chopped)
- 2 Tbsp green onion or chives (to garnish)
How to Make Loaded Mashed Potato Casserole
Step 1: Preheat the Oven
Preheat your oven to 375˚F. While it warms up, place the peeled and cubed potatoes in a pot. Cover them with enough water to submerge completely. Bring this mixture to a boil over medium/high heat. Once boiling, reduce the heat to medium and season with salt. Cook until you can easily pierce the potatoes with a knife. Drain well afterward.
Step 2: Prepare the Milk Mixture
In a small saucepan over low heat, add the unsalted butter and milk. Stir until the butter has melted completely. Turn off the heat but keep the saucepan on the stovetop to maintain warmth. Add sour cream to this mixture and whisk until fully combined.
Step 3: Mash the Potatoes
Using either a hand mixer or potato masher, mash the drained potatoes until they achieve a creamy consistency. Gradually incorporate the warm milk mixture into the mashed potatoes until everything is well mixed. Transfer this creamy mixture into your baking dish.
Step 4: Cook Turkey Bacon
In a medium skillet over medium heat, sauté chopped turkey bacon until it turns golden brown and crispy. Afterward, sprinkle this crispy bacon over your potato mixture in the baking dish. Top everything with freshly shredded Colby Jack cheese.
Step 5: Bake Your Casserole
Cover your baking dish with aluminum foil and place it in your preheated oven. Bake at 375˚F for about 25 minutes. After this time, remove the foil and continue baking for an additional 10 minutes or until the cheese is bubbly and melted.

Common Mistakes to Avoid
Many cooks encounter pitfalls when making Loaded Mashed Potato Casserole. Here are some common mistakes and how to avoid them.
- Skipping the seasoning – Failing to season the potatoes while boiling can lead to bland flavor. Always add salt to the cooking water for a better taste.
- Overcooking the potatoes – If you cook the potatoes too long, they can become mushy. Keep an eye on them and test with a fork to check for doneness.
- Not mashing thoroughly – Leaving chunks in your potatoes will affect the creamy texture. Make sure to mash or beat until smooth before adding other ingredients.
- Using cold ingredients – Cold milk or butter can cool down your casserole and prevent it from baking evenly. Always use warm ingredients for a smooth mix.
- Neglecting the baking time – Removing the casserole too early may result in unevenly melted cheese. Ensure it’s baked long enough for complete warmth and gooey cheese.
Refrigerator Storage
- Store leftovers in an airtight container.
- Refrigerate within two hours of cooking.
