Ingredients

8 large eggs
1 cup milk (whole or 2%)
1 teaspoon Dijon mustard (optional for a hint of flavor)
1/2 teaspoon salt
1/4 teaspoon black pepper
1 tablespoon olive oil or unsalted butter
1 cup broccoli florets, chopped into small bite-sized pieces
1 cup mushrooms, sliced (white or cremini)
1 small onion, finely diced
1 1/2 cups Swiss cheese, shredded
1/4 cup Parmesan cheese, grated (optional for extra flavor)
1 teaspoon garlic powder or 1 clove garlic, minced
Fresh herbs for garnish (optional, such as parsley or chives)

Directions

Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil or butter to prevent sticking.
Prepare the Vegetables
Heat a skillet over medium heat and add olive oil or butter. Sauté the diced onion until translucent, about 3–4 minutes. Add the mushrooms and cook until they release their moisture and turn golden brown, about 5 minutes. Add the broccoli and garlic, cooking for another 2–3 minutes until slightly tender. Remove from heat and let cool slightly.
Whisk the Eggs
In a large mixing bowl, whisk together the eggs, milk, Dijon mustard (if using), salt, black pepper, and garlic powder until smooth and slightly frothy.
Combine Ingredients
Stir the sautéed vegetables and Swiss cheese into the egg mixture, reserving a small handful of cheese for topping.
Transfer to Baking Dish
Pour the mixture into the prepared baking dish, spreading it evenly. Sprinkle the remaining Swiss cheese and Parmesan cheese over the top for a golden, bubbly finish.
Bake
Place the dish in the preheated oven and bake for 30–35 minutes, or until the egg bake is set in the center and lightly golden on top. To test, insert a knife into the center—if it comes out clean, the bake is ready.
Cool and Serve
Allow the egg bake to cool for 5–10 minutes before slicing. Garnish with fresh herbs if desired. Serve warm with your choice of sides or enjoy it as-is for a wholesome, satisfying meal.

Tips for the Perfect Egg Bake

1. Don’t Overcook: Eggs can become rubbery if baked too long. Keep an eye on the bake in the last 5 minutes and remove when the center is just set.

2. Customize Your Veggies: Feel free to swap broccoli for spinach, zucchini, or bell peppers, and try different mushrooms for varied texture and flavor.

3. Cheese Variations: Swiss cheese is mild and nutty, but Gruyère, cheddar, or mozzarella can work beautifully for a slightly different taste profile.

4. Make-Ahead Option: Assemble the egg bake the night before, cover with foil, and refrigerate. Bake the next morning for a quick and easy breakfast.

5. Freezing: This egg bake freezes well. Portion it into individual servings, wrap tightly in plastic wrap and foil, and freeze for up to 2 months. Reheat in the oven at 350°F (175°C) until warmed through.

Why Swiss Cheese Works So Well

Swiss cheese is a classic choice for egg bakes because it melts beautifully, creating a creamy, gooey texture that binds the vegetables and eggs together. Its nutty flavor complements both the mild sweetness of broccoli and the earthiness of mushrooms. For those seeking a sharper bite, combining Swiss with a small amount of aged cheddar or Gruyère can add depth and richness without overpowering the delicate flavors of the vegetables.

Health Benefits of This Egg Bake

Protein-Packed: Eggs are a complete protein, providing essential amino acids that support muscle growth, repair, and overall health.

Rich in Vitamins and Minerals: Broccoli adds vitamin C, vitamin K, and fiber, while mushrooms provide antioxidants and B vitamins. Together, they make this egg bake both satisfying and nutrient-dense.

Lower in Carbs: Perfect for those looking for a low-carb or keto-friendly breakfast option. Pair with a small portion of whole-grain toast if you want a balanced plate.

Versatile for Meal Planning: This egg bake works well for meal prep. It can be eaten for breakfast, lunch, or dinner, offering convenience without sacrificing nutrition or flavor.

Serving Suggestions

Brunch Spread: Serve alongside fresh fruit, a green salad, or roasted potatoes for a brunch that feels both indulgent and wholesome.
Light Dinner: Pair with a simple mixed greens salad dressed with olive oil and lemon juice for a light, satisfying dinner.
On-the-Go Breakfast: Cut into squares, wrap individually, and take for a protein-packed breakfast on busy mornings.

Variations to Try

1. Spinach & Feta: Replace broccoli with fresh spinach and Swiss cheese with crumbled feta for a Mediterranean twist.

2. Sun-Dried Tomato & Basil: Add chopped sun-dried tomatoes and fresh basil leaves for a vibrant flavor boost.

3. Roasted Veggie: Roast bell peppers, zucchini, and cherry tomatoes beforehand for a colorful, caramelized variation.

4. Mushroom Medley: Use a mix of shiitake, oyster, and cremini mushrooms to elevate the earthy richness of the egg bake.
