Finally, the bake and the breathless wait. Gently spoon the soufflé mixture into the prepared ramekins, filling them to the top. Use a straight edge (like a bench scraper or knife) to level the tops. Run your thumb around the inside rim of each ramekin to create a shallow “moat.” This helps the soufflé rise straight up with a classic top hat shape. Immediately place the baking sheet with the filled ramekins into the preheated 375°F (190°C) oven. Do not open the door for the first 15 minutes! Bake for 15-18 minutes total, until the tops are puffed, golden, and just set. They should have a slight, gentle jiggle at the center when you tap the tray.
Pro Tips for Best Results
For the highest, most stable rise, I always add a tablespoon of granulated sugar to my egg whites after they’ve reached soft peaks, not at the beginning. Adding it gradually as they whip helps create a stronger, more stable meringue structure that can support the weight of the lemon base.
Room temperature ingredients are so vital that I take extra steps. If I forget to take my eggs out, I place the whole eggs (in their shells) in a bowl of very warm water for 10 minutes. For the lemons, I microwave them for 10 seconds and roll them on the counter before juicing to get every last drop.
Have everything ready—prepped ramekins, measured ingredients, mixer set up—before you start cooking the lemon base. The base can’t sit too long before being folded into the meringue, and the meringue shouldn’t sit before baking. A smooth, swift workflow is the secret to a stress-free soufflé experience.
Common Mistakes to Avoid
My biggest first-time mistake was opening the oven door to “peek” during the first half of baking. The rush of cold air caused my beautiful soufflés to collapse prematurely. Trust the process and the oven light. That first undisturbed 15 minutes is sacred for setting the structure.(See the next page below to continue…)
