Instructions
  1. In a small microwave-safe bowl, heat 1 tablespoon (14 grams) butter on high in 10-second intervals until melted.
  2. Brush insides of 6 (9.5-ounce or 10-ounce) ramekins with melted butter; coat with Parmesan (if using), shaking out excess. (Alternatively, coat insides with flour, shaking out excess.) Refrigerate until ready to use.
  3. In a large, high-sided saucepan, melt remaining 3 tablespoons (42 grams) butter over medium-high heat. Add bell pepper and leeks; cook, stirring frequently, until tender, 4 to 6 minutes, adjusting heat as necessary to prevent excess browning. Reserve 1½ tablespoons (20 grams) vegetable mixture in a small bowl.
  4. Sprinkle flour over remaining vegetable mixture in pan; cook, stirring constantly,
  5. for 1 minute. Gradually stir in milk until well combined; reduce heat to medium, and cook, stirring constantly, until thickened, about 2 minutes, adjusting heat as necessary. Remove from heat; gradually stir in Havarti until melted and well combined. Stir in ¼ cup (12 grams) chives, salt, mustard, and garlic powder. Transfer mixture to a large bowl; gradually whisk in egg yolks.
  6. Set SHARP® SuperSteam+TM Built-In Wall Oven (SSC2489DS) to Manual/ Steam Bake/Water Bath/300°F/22 minutes/Start. (Oven will preheat.)
  7. Meanwhile, in the bowl of a stand mixer fitted with the whisk attachment, beat egg whites and cream of tartar at medium-high speed until stiff peaks form. Stir one-third of egg white mixture into vegetable mixture; fold in remaining egg white mixture in two additions until combined.
  8. Place prepared ramekins on 1 tray; evenly divide batter among prepared ramekins, gently smoothing into an even layer with a small offset spatula. Sprinkle tops with reserved vegetable mixture and remaining 2 teaspoons (2 grams) chives. Place tray on lower level of oven. Press Start.
  9. Bake for 22 minutes until puffed and golden. Serve immediately.
