Twice Baked Potato Casserole is the ultimate comfort food that combines the classic flavors of a baked potato with ooey-gooey cheese and creamy goodness!

Ingredients

4 large russet potatoes
1 cup sour cream
1 cup shredded cheddar cheese
1/2 cup milk
1/4 cup butter
1 teaspoon garlic powder
1/2 teaspoon onion powder
Salt and pepper to taste
3 green onions, sliced

Instructions

Preheat the oven to 400°F (200°C).

Scrub the russet potatoes and pierce each potato with a fork. Bake for about 45 minutes or until tender.

Once the potatoes are cool enough to handle, scoop out the insides into a large mixing bowl.

Add sour cream, shredded cheddar cheese, milk, butter, garlic powder, onion powder, salt, and pepper to the bowl. Mash until well combined and creamy.

Fold in half of the green onions into the potato mixture.

Transfer the mixture to a greased 9x13 inch casserole dish, spreading evenly.

Sprinkle the remaining cheddar cheese on top.

Bake in the oven for an additional 20-25 minutes, until the cheese is melted and bubbly.

Garnish with the remaining green onions before serving.

Chef's Tips

For a richer flavor, use a combination of cheddar and pepper jack cheese.

Make sure to bake the potatoes thoroughly for the best texture.

Add additional toppings like cooked bacon or broccoli for a unique twist.

Troubleshooting

If the mixture is too dry, add more milk or sour cream.

If the top doesn't brown, broil for a few minutes at the end to achieve a golden color.

Make sure potatoes are completely cool before scooping to avoid mash consistency.

Recipe Variations

Add cooked broccoli for a cheesy broccoli potato casserole.

Incorporate cooked bacon or sausage for a meatier variant.

Mix in different cheeses such as gouda or mozzarella.

Healthy Alternatives

Substitute Greek yogurt for sour cream to reduce fat content.

Use low-fat cheese to lower calorie count.

Replace butter with olive oil for a healthier fat option.

Serving Suggestions

Serve alongside grilled chicken or a fresh garden salad.

Pair with a hot bowl of soup for a complete meal.

Top with crispy bacon bits or additional green onions.
