Ingredients
• For the Soufflé (Serves 4-6)
• 1 lb / 450 g fresh zucchini
• 1 small yellow onion
• 5 Tbs / 70 g butter, divided
• ¾ tsp / 4 g salt, plus more to taste
• ¼ to ½ tsp / 1-2 g dried basil, crushed
• Freshly ground black pepper to taste
• 3 Tbs / 25 g all-purpose flour
• 1⅓ cups / 320 ml warm milk
• 6 large egg yolks
• 2 Tbs / 15 g grated Parmesan cheese
• 7 large egg whites
• pinch of cream of tartar
• For Serving
• Hollandaise sauce or a cheese sauce
Instructions
1. Preheat your oven to 350°F / 175°C. Generously butter a 2-quart soufflé dish.
2. Trim, wash, and grate the zucchini. Peel and finely chop the onion. In a medium skillet, melt 2 tablespoons of the butter over medium heat and sauté the onions until just soft. Add the grated zucchini and increase the heat, tossing and stirring frequently until the zucchini is tender and any excess water has evaporated. Stir in the salt, basil, and a few grinds of black pepper. Cook for another minute, then remove from the heat and set aside.
3. To make the béchamel base, melt the remaining 3 tablespoons of butter in a medium, heavy-bottomed saucepan over low heat. Whisk in the flour to form a smooth paste (a roux) and cook for 2 minutes, stirring constantly. Gradually pour in the warm milk, whisking continuously to prevent lumps. Increase the heat to medium and continue whisking until the sauce is thick, smooth, and bubbly.
4. Remove the sauce from the heat. Beat in the egg yolks one at a time, ensuring each is fully incorporated before adding the next. Stir in the grated Parmesan cheese and the cooked zucchini mixture. Taste and adjust seasoning with more salt and pepper if needed.
5. In a separate, large, clean bowl, beat the egg whites with a pinch of cream of tartar using an electric mixer until they form stiff, glossy peaks. Be careful not to overbeat.
6. Gently stir about a quarter of the beaten egg whites into the zucchini base to lighten it. Then, carefully fold in the remaining egg whites in two batches using a large spatula, being careful not to deflate the mixture. The goal is to have a light, airy batter with minimal streaks of white.
7. Pour the mixture into your prepared soufflé dish. Bake for 35 to 40 minutes, or until the soufflé is puffed, beautifully golden brown on top, and a skewer inserted into the center comes out mostly clean.
8. Serve immediately! Soufflés wait for no one. Top with a drizzle of Hollandaise or cheese sauce, if desired.

Pro Tips
• for a Perfect Soufflé
• Use room temperature eggs. The whites will whip up to a much greater volume, giving your soufflé a lighter texture and a better rise.
• Don’t peek! Opening the oven door mid-bake can cause a sudden temperature drop, making your soufflé collapse. Watch its progress through the oven window.
• Fold, don’t stir. When incorporating the whipped egg whites, use a gentle, sweeping motion with a spatula to maintain as much air in the batter as possible.
• Serve immediately. The magic of a soufflé is its magnificent, puffy rise straight from the oven. Have your guests seated and ready to enjoy it the moment it’s done.
FAQ
Q: Can I make this zucchini soufflé gluten-free
A: Yes, you can! To make this soufflé gluten-free, simply substitute the all-purpose flour in the béchamel base with an equal amount of a good quality gluten-free all-purpose flour blend. Ensure your blend contains a binder like xanthan gum for the best texture.
Q: Is this vegetarian soufflé a good source of protein
A: Absolutely. This zucchini soufflé is an excellent source of vegetarian protein, primarily from the 13 large eggs and the Parmesan cheese. Each serving provides an estimated 14 grams of high-quality protein, making it a satisfying and nutritious main course for a light lunch or brunch.
Q: How do I store leftover zucchini soufflé
A: While a soufflé is best enjoyed immediately, you can store leftovers. Allow it to cool completely, then cover the dish tightly and refrigerate for up to 2 days. Note that it will deflate. To reheat, place it in an oven-safe dish and warm at 325°F / 160°C until heated through. It won’t regain its original height but will still be delicious.
Q: Can I use a different cheese in this recipe
A: Certainly. While Parmesan adds a wonderful nutty and salty flavor, you can substitute it with other hard, aged cheeses. Gruyère, Pecorino Romano, or a sharp white cheddar would all be delicious vegetarian-friendly options.
