 Instructions

Step 1

Preheat oven to 375°F (190°C). Grease a 9-inch (23 cm) square baking dish or similar casserole dish.

Step 2

Heat butter and olive oil in a skillet over medium heat. Sauté the onion for 4–5 minutes until softened.

Step 3

Add garlic and cook for 30 seconds until fragrant.

Step 4

Add spinach and cook until wilted (or heat thawed frozen spinach until warmed through). Let cool slightly.

Step 5

In a large bowl, whisk together eggs and milk until smooth.

Step 6

Mix in ricotta, mozzarella, Parmesan, flour, baking powder, salt, pepper, Italian seasoning, and nutmeg.

Step 7

Fold the cooked spinach mixture into the egg mixture until evenly combined.

Step 8

Pour into the prepared baking dish.

Step 9

Top with spoonfuls of ricotta, extra mozzarella, and Parmesan.

Step 10

Bake for 40–45 minutes, or until puffed, golden brown, and the center is just set.

Step 11

Allow the soufflé to rest for 10 minutes before serving. It will settle slightly as it cools.

Frequently Asked Questions (Q&A)

Q1: Can I use frozen spinach?
Yes. Thaw completely and squeeze out as much moisture as possible before adding it to the mixture.

Yes. Assemble the casserole, cover, and refrigerate for up to 24 hours. Bake just before serving.

Q3: Can I freeze it?
Yes. Bake, cool completely, wrap well, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Q4: Why did my soufflé sink?
A slight collapse is normal as it cools. Overmixing or opening the oven too early can also cause it to deflate.

Feta, goat cheese, Gruyère, cheddar, or Swiss cheese can be used for different flavors.

Q8: How do I know when it’s done?
The center should be set with only a slight jiggle, and the top should be puffed and golden brown.

Q9: How should leftovers be stored?
Refrigerate in an airtight container for up to 4 days. Reheat in the oven or microwave until warmed through.
