Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• Fresh spinach, chopped
• Butter
• All-purpose flour
• Whole milk
• Eggs, separated
• Gruyère cheese, grated
• Parmesan cheese, grated
• Onion, finely chopped
• Garlic, minced
• Nutmeg
• Salt
• Black pepper
• Cream of tartar (optional, for stabilizing egg whites)
• Butter and grated Parmesan, for preparing the baking dish

Directions

1. Preheat the oven to 375°F (190°C). Butter a soufflé dish or deep baking dish and lightly coat it with grated Parmesan cheese.
2. Heat butter in a skillet over medium heat and sauté the onion until softened.
3. Add the garlic and cook for about 30 seconds, then stir in the spinach until wilted. Remove from the heat and allow it to cool slightly.
4. In a saucepan, melt butter over medium heat and whisk in the flour to form a roux. Cook for 1–2 minutes.
5. Gradually whisk in the milk until smooth and thickened.
6. Remove from the heat and stir in the Gruyère, Parmesan, nutmeg, salt, and black pepper.
7. Beat the egg yolks into the cheese sauce one at a time, then stir in the spinach mixture.
8. In a clean bowl, beat the egg whites with the cream of tartar until stiff peaks form.
9. Gently fold one-third of the egg whites into the spinach mixture to lighten it, then carefully fold in the remaining egg whites until just combined.
10. Spoon the mixture into the prepared dish and smooth the top.
11. Bake for 30–35 minutes without opening the oven door until the soufflé is puffed and golden brown.
12. Serve immediately before the soufflé begins to deflate.

Servings and timing

• Prep time: 20 minutes
• Cook time: 30–35 minutes

Variations

• Mediterranean style: Add crumbled feta cheese and fresh dill.

• Herb-infused: Add fresh chives, parsley, or thyme.

Storage/Reheating

Soufflés are best enjoyed immediately after baking. However, leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a 325°F (160°C) oven for 10–15 minutes or in the microwave on low power. While the soufflé won’t regain its original height, it will still be delicious.

FAQs

Why did my soufflé fall?

Soufflés naturally begin to deflate after they’re removed from the oven. Overmixing or opening the oven door during baking can also affect the rise.

Can I use frozen spinach?

Yes. Thaw it completely and squeeze out as much moisture as possible before using.

What cheese works best?

Gruyère is the classic choice, but Swiss, cheddar, or Parmesan also work well.

Can I prepare the soufflé ahead of time?

You can prepare the base in advance, but it’s best to fold in the egg whites and bake just before serving.

Why are the egg whites important?

Whipped egg whites create the light, airy structure that gives a soufflé its signature rise.

Can I make individual soufflés?

Yes. Divide the mixture among buttered ramekins and reduce the baking time to about 20–25 minutes.

Is cream of tartar necessary?

No. It helps stabilize the egg whites but isn’t essential.

How do I know when the soufflé is done?

The top should be golden brown and puffed, and the center should be just set with a slight wobble.

What can I serve with Spinach Soufflé?

It pairs beautifully with a green salad, roasted vegetables, soup, or crusty bread.

Can I make this recipe gluten-free?

Yes. Replace the all-purpose flour with a gluten-free flour blend suitable for thickening sauces.
