Ingredients
  

  • 10 large eggs
  • 1/2 cup milk or unsweetened almond milk
  • 1 cup cherry tomatoes, halved
  • 2 cups fresh baby spinach, roughly chopped
  • 1 small red onion, thinly sliced
  • 1 red bell pepper, diced
  • 1/2 cup pitted Kalamata olives, halved
  • 3/4 cup crumbled feta cheese
  • 2 tablespoons extra-virgin olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon dried oregano
  • 1/2 teaspoon dried thyme (or 1 teaspoon fresh leaves)
  • 1/4 teaspoon crushed red pepper flakes (optional)
  • 1 lemon, zested (about 1 teaspoon) and 1 tablespoon juice
  • Salt and freshly ground black pepper, to taste
  • Fresh parsley or dill, chopped, for garnish
  • Nonstick cooking spray or additional olive oil for the baking dish

Instructions
 

  • Prep your pan: Heat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or olive oil.
  • Sauté the veggies: Warm 2 tablespoons olive oil in a skillet over medium heat. Add onion and bell pepper with a pinch of salt. Cook 5–6 minutes until softened. Stir in garlic for 30 seconds.
  • Wilt the greens: Add chopped spinach to the skillet. Cook 1–2 minutes until just wilted. Remove from heat and let cool slightly.
  • Whisk the eggs: In a large bowl, whisk eggs, milk, oregano, thyme, lemon zest, lemon juice, red pepper flakes (if using), 1/2 teaspoon salt, and several grinds of black pepper until smooth and frothy.
  • Layer the casserole: Spread the sautéed vegetables evenly in the baking dish. Sprinkle cherry tomatoes and olives over the top. Pour the egg mixture over everything. Scatter feta evenly.
  • Bake: Place on the center rack and bake 22–28 minutes, until the eggs are just set in the center and the edges are lightly golden. The center should barely jiggle.
  • Rest and garnish: Let the casserole rest 5–10 minutes. Finish with chopped parsley or dill and a few extra cracks of pepper.
  • Serve: Cut into squares. Enjoy warm, or at room temperature with a simple green salad or toasted whole-grain bread.
