A hearty Cheesy Cabbage Casserole Recipe made with cabbage, cauliflower, eggs, ricotta, sour cream, and melted cheeses baked to golden perfection—an easy, comforting dish for any occasion.
Preheat the oven to 375°F (190°C). Lightly grease a 9-inch round baking dish with cooking spray and set aside.
Sauté the Vegetables
Heat olive oil in a skillet over medium heat. Add the diced onion and cook until softened. Stir in the shredded cabbage with 1 teaspoon of kosher salt. Sauté for 1 minute. Transfer the mixture into the prepared baking dish.
Prepare the Egg Mixture
In a medium bowl, whisk together the eggs, ricotta cheese, sour cream, garlic powder, 1 teaspoon kosher salt, and black pepper until smooth.
Incorporate Dry Ingredients
In a separate small bowl, stir together the flour, corn starch, and baking powder. Gradually whisk the dry mixture into the egg mixture until fully combined.
Assemble the Casserole
Pour the egg batter evenly over the cabbage and onion mixture. Arrange the cauliflower florets over the top. Sprinkle with mozzarella and cheddar cheeses, then finish with chopped thyme.
Bake
Place the casserole on the center rack and bake for approximately 35 minutes, or until the top is golden brown and set. Remove from the oven and allow it to cool for 5 minutes before serving.
