- Butter, room temperature, for greasing the pan
- 2 Tbsp grated Parmesan
- 3 Tbsp butter
- 3 Tbsp flour
- 1 tsp dry mustard
- 1/2 tsp garlic powder
- 1/8 tsp kosher salt
- 1 1/3 cups milk, hot
- 4 large egg yolks
- 6 ounces sharp Cheddar
- 5 egg whites plus 1 tablespoon water
- 1/2 tsp cream of tartar
Use room temperature butter to grease an 8-inch souffle mold. Add the grated Parmesan and roll around the mold to cover the sides. Cover with plastic wrap and place into the freezer for 5 minutes.
Preheat oven to 375 degrees F.
In a small saucepan, heat the butter. Allow all of the water to cook out.
In a separate bowl combine the flour, dry mustard, garlic powder, and kosher salt. Whisk this mixture into the melted butter. Cook for 2 minutes.
Whisk in the hot milk and turn the heat to high. Once the mixture reaches a boil, remove from the heat.
In a separate bowl, beat the egg yolks to a creamy consistency. Temper the yolks into the milk mixture, constantly whisking. Remove from the heat and add the cheese. Whisk until incorporated.
In a separate bowl, using a hand mixer, whip the egg whites and cream of tartar until glossy and firm. Add 1/4 of the mixture to the base. Continue to add the whites by thirds, folding very gently.
Pour the mixture into the souffle pan. Fill until 1/2-inch from the top. Place on an aluminum pie pan. Bake for 35 minutes - allow to cool slightly before serving.
