Ingredient List

This easy dish is made with simple ingredients you can easily find at your local grocery store.

• Potatoes. I used yellow table potatoes. You could also use Yukon gold potatoes, red potatoes, or russet potatoes. I peeled my potatoes, but if you prefer, you can leave the skin on, or peel some and leave the skin on some. If they were tender new potatoes, I would leave the skin on for extra flavor.
• Bacon adds terrific flavor to this side dish.
• Butter. Cold butter mixes better with mashed potatoes. Mix the butter in with the potatoes first before adding the sour cream and milk.
• Sour cream adds creaminess and tanginess to mashed potatoes.
• Milk helps to create a fluffier texture, and also enhances the flavor.
• Onion powder adds a warm flavor to the potatoes without being overpowering.
• Garlic powder adds a nice mild garlic flavor to the casserole. You can increase the amount if you like a stronger garlic flavor.
• Black pepper adds a subtle kick to the dish.
• Seasoning salt enhances the natural flavors in the casserole.
• Shredded cheddar cheese makes this dish cheesy and delicious.
• Green onions add fantastic color and a subtle onion flavor. I only used the green part of the onion, not the white part.

Instructions

Preheat the oven to 400 degrees F.

Wash and scrub the potatoes with cold water.

Pierce the potatoes all over with a fork, about 7 or 8 times. This is so that the steam inside can release why the potatoes are baking, which makes the potato fluffier.

Next, place potatoes on the top rack of the oven. Bake potatoes until they are tender when pierced with a fork. This will take anywhere from 45 minutes to 60 minutes, depending on the size of your potatoes and how hot your oven is. My potatoes were medium-sized, and they were done at 52 minutes.

Smaller potatoes will cook faster than larger ones, so just remove them as they are ready.

While the potatoes are cooking, cook the bacon. Place the bacon on a cutting board, and carefully use a sharp knife to cut the bacon into bite-size pieces.

Add the bacon to a large skillet, and cook the bacon over medium-low heat until crispy. Make sure to stir it often to prevent burning.

Spoon the cooked bacon onto a plate lined with a paper towel. This will help absorb the grease.

Tip: Cook bacon in the air fryer if you have one. Cook it whole and break it apart after it cooks.

When the potatoes are fully cooked, remove them from the oven and turn the oven temperature down to 350 degrees F.

When the potatoes are cool enough to handle, use a sharp knife to peel the skin off. Cut them into quarters and place them in a large bowl.

You can also leave the skins on if you like.

Next, add cold butter to the potatoes and mash potatoes with a potato masher. The butter will melt into the potatoes while you are mashing.

Next, add milk, sour cream, onion powder, garlic powder, seasoning salt, and black pepper.

Mash the ingredients into the potatoes. However, don't overmix, as this will cause the potatoes to get gummy. Mix everything together with a large spoon.

Reserve some of the cooked bacon, shredded cheese, and green onion to sprinkle on top after the casserole is assembled.

Add the rest of the crispy bacon, green onion, and shredded cheese to the bowl with the potato mixture.

Transfer the mixture to a greased 9 x 13 casserole dish. Smooth out the top with the back of a spoon.

Sprinkle the remaining cheese, bacon, and green onions on top of the potatoes.

Place the casserole in the oven - because, you know, it's twice-baked, and cook the casserole for about 30 minutes, or until the mixture is heated through and the cheese is melted and bubbly on top.

Enjoy!

Make-ahead instructions

To make this loaded potato casserole ahead, follow all of the instructions, up until you have it in the casserole dish and ready to bake. At this point, you can cover it with a layer of plastic wrap and a layer of aluminum foil, and place it in the refrigerator for up to 2 days.

When you are ready to bake it, remove the plastic wrap, preheat your oven to 350 degrees F, cover the casserole with aluminum foil, and bake for 30 minutes. Remove the aluminum foil and continue to bake until the casserole is hot and bubbly.

Substitutions

• Milk - use any type of milk you like. Some good substitutions are whole milk, or even half-and-half or heavy cream.
• Garlic powder and onion powder - you could finely chop fresh garlic and the white part of the green onions. Cook them with the bacon before adding them to the casserole.
• Bacon - use any type of bacon; thick-cut bacon, thin-cut bacon, or even turkey bacon. You can also use diced ham or bacon bits.
• Cheddar cheese- use any type of cheese in this recipe; they will all taste fantastic.
• Green onions - use diced chives instead.

Variations

• Spicy - add red pepper flakes or hot sauce
• Deluxe - add diced vegetables such as broccoli, cauliflower, or carrots
• Texture - Use baked potatoes with the skin on and some potatoes peeled.
• Cheesy - Use a different type of cheese, such as mozzarella or Parmesan cheese.
