Instructions

  1. Step 1: Preheat oven to 375°F. Toss 1 diced large eggplant (1/2-inch cubes) with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Spread on a baking sheet and roast for 20 minutes until tender and edges are golden.
  2. Step 2: While eggplant roasts, heat 1 tbsp olive oil in a skillet over medium heat. Add 2 minced garlic cloves and sauté for 30 seconds until fragrant.
  3. Step 3: Add 3 cups roughly chopped fresh spinach leaves to the skillet and cook until wilted, about 2 minutes. Remove from heat.
  4. Step 4: In a large bowl, whisk together 8 large eggs, 1/4 cup heavy cream, 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 tsp dried oregano until smooth.
  5. Step 5: Fold roasted eggplant, sautéed spinach, and 1/2 cup grated Parmesan cheese into the egg mixture.
  6. Step 6: Grease a 9-inch ovenproof skillet or baking dish with olive oil and pour in the egg mixture, spreading evenly.
  7. Step 7: Bake in the preheated oven for 25-30 minutes until the frittata is set and lightly golden on top.
  8. Step 8: Let cool for 5 minutes before slicing into 6 servings. Serve warm or at room temperature.
