Description

These savory feta and mushroom brunch squares are an easy, make-ahead breakfast or brunch option packed with flavor from sautéed mushrooms, creamy feta, and fluffy eggs. Perfect for meal prep, gatherings, or a healthy weekday start.


Ingredients

  • 6 large eggs
  • ½ cup milk or half-and-half
  • 1 tbsp olive oil or butter
  • 1 cup mushrooms, sliced (cremini or white button)
  • 1 clove garlic, minced
  • ½ cup crumbled feta cheese
  • 2 green onions or 1 tbsp chives, chopped
  • ½ tsp salt
  • ¼ tsp black pepper
  • Optional: ½ cup chopped fresh spinach, sun-dried tomatoes, fresh thyme or oregano

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×9-inch baking dish.

  2. In a skillet, heat olive oil over medium heat and sauté mushrooms until tender and golden (6–8 minutes). Add garlic and cook for another 30 seconds.

  3. In a large bowl, whisk together eggs, milk, salt, and pepper.

  4. Stir in the sautéed mushrooms, feta cheese, and green onions.

  5. Pour the mixture into the baking dish and spread evenly.

  6. Bake for 30–35 minutes, or until the center is set and the top is lightly golden.

  7. Let cool for a few minutes, slice into squares, and serve warm or at room temperature.


Notes

  • This dish freezes well—wrap individual squares tightly and thaw overnight in the fridge before reheating.
  • You can easily double the recipe and bake in a 9×13-inch pan for a crowd.
