Description

A warm, cheesy breakfast or brunch option that combines tender broccoli, earthy mushrooms, and gooey Swiss cheese in a fluffy baked egg base. Perfect for a cozy morning or a weekend gathering, this egg bake is both satisfying and nourishing.


Ingredients

Scale
  • 8 large eggs

  • 1 cup milk (whole or 2%)

  • 1 teaspoon Dijon mustard (optional)

  • 1/2 teaspoon salt

  • 1/4 teaspoon black pepper

  • 1 tablespoon olive oil or unsalted butter

  • 1 cup broccoli florets, chopped

  • 1 cup mushrooms, sliced

  • 1 small onion, finely diced

  • 1 1/2 cups Swiss cheese, shredded

  • 1/4 cup Parmesan cheese, grated (optional)

  • 1 teaspoon garlic powder or 1 clove garlic, minced

  • Fresh herbs for garnish (optional)


Instructions

  • Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.

  • Heat olive oil or butter in a skillet over medium heat. Sauté onion until translucent, about 3–4 minutes.

  • Add mushrooms and cook until golden brown, about 5 minutes.

  • Add broccoli and garlic, cooking 2–3 more minutes until slightly tender. Remove from heat.

  • In a large bowl, whisk eggs, milk, Dijon mustard, salt, black pepper, and garlic powder until smooth.

  • Stir in sautéed vegetables and Swiss cheese, reserving some cheese for topping.

  • Pour mixture into prepared baking dish and sprinkle with remaining Swiss and Parmesan cheese.

  • Bake 30–35 minutes until set in the center and lightly golden. Test with a knife; it should come out clean.

  • Let cool 5–10 minutes, garnish with fresh herbs if desired, and serve warm.

Notes

  • Do not overcook to avoid rubbery eggs.

  • Swap broccoli with spinach, zucchini, or bell peppers for variety.

  • Cheese alternatives like cheddar or Gruyère work well.

  • Make-ahead option: assemble overnight and bake in the morning.

  • Leftovers can be stored in the fridge up to 4 days or frozen for 2 months.
