Ingredients

• 2 cups leftover mashed potatoes
• 4 large eggs
• 0.5 cups milk
• 0.5 cups grated cheddar cheese
• 2 tablespoons grated Parmesan cheese
• 1 tablespoon unsalted butter
• 1 tablespoon all-purpose flour
• 0.5 teaspoons salt
• 0.25 teaspoons black pepper
• 0.25 teaspoons garlic powder
• 1 tablespoon fresh parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 1.5-quart soufflé dish or an 8-inch baking dish with butter and lightly dust with flour, tapping out excess.

Step 2

Separate the eggs, placing the yolks in a small bowl and the whites in a large mixing bowl. Ensure the whites are free of any yolk impurities.

Step 3

In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1 minute, whisking constantly to form a roux.

Step 4

Gradually whisk in the milk and cook until the mixture thickens, about 2-3 minutes.

Step 5

Add the mashed potatoes, cheddar cheese, Parmesan cheese, salt, pepper, and garlic powder to the saucepan. Stir until smooth and combined. Remove from heat and allow the mixture to cool slightly.

Step 6

Whisk the egg yolks into the potato mixture, one at a time, until incorporated.

Step 7

Using a handheld or stand mixer, beat the egg whites on medium-high speed until stiff peaks form. This will take about 3-5 minutes.

Step 8

Gently fold one-third of the beaten egg whites into the potato mixture to lighten it. Then, fold in the remaining egg whites in two batches, being careful not to deflate the mixture.

Step 9

Pour the soufflé mixture into the prepared dish and smooth the top with a spatula.

Step 10

Bake in the preheated oven for 25-30 minutes, or until the soufflé is puffed and golden brown. Avoid opening the oven door while baking.

Step 11

Serve immediately, garnished with fresh parsley if desired. Enjoy your fluffy and delicious leftover mashed potato soufflé!
