Ingredients

• 8 ounces fresh crab meat
• 4 cups fresh spinach
• 6 eggs
• 1.5 cups heavy cream
• 1 cup shredded Swiss cheese
• 0.5 cup grated Parmesan cheese
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 2 tablespoons butter
• 1 teaspoon salt
• 0.5 teaspoon ground black pepper
• 0.25 teaspoon ground nutmeg

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.

Step 2

Rinse the fresh spinach under cold water and pat dry. Heat a large skillet over medium heat, add 1 tablespoon of butter, and sauté the spinach until wilted, about 2-3 minutes. Remove the spinach from the skillet, drain any excess moisture, and set aside.

Step 3

In the same skillet, melt the remaining 1 tablespoon of butter. Add the chopped onion and minced garlic, sautéing for 4-5 minutes until softened and fragrant. Remove from heat and set aside.

Step 4

In a large mixing bowl, whisk the eggs until well-beaten. Gradually mix in the heavy cream, salt, pepper, and nutmeg.

Step 5

Stir in the sautéed spinach, onion mixture, shredded Swiss cheese, and grated Parmesan cheese. Then, gently fold in the crab meat without breaking it apart too much.

Step 6

Pour the mixture into the prepared baking dish, spreading it out evenly.

Step 7

Bake in the preheated oven for 40-45 minutes until the top is golden brown and the center is set. You can test it by inserting a knife into the center—if it comes out clean, the casserole is done.

Step 8

Allow the casserole to cool for 5-10 minutes before slicing and serving. Enjoy!
