Total Time: 35 minutes
Servings: 4–6

Ingredients

6 large eggs

1 ½ cups mushrooms, sliced

1 small onion, finely chopped

1 cup shredded Swiss cheese

1 tbsp olive oil or butter

Salt and pepper, to taste

Instructions

Preheat oven

Preheat oven to 375°F (190°C).

Grease an 8-inch pie dish or a similar oven-safe baking dish with olive oil or butter.

Cook the vegetables

Heat olive oil or butter in a skillet over medium heat.

Sauté onions for 2–3 minutes until softened.

Add mushrooms and cook until tender and slightly browned, about 5–6 minutes.

Season with salt and pepper. Remove from heat and let cool slightly.

Prepare the egg mixture

In a bowl, whisk together eggs, salt, and pepper until fully combined.

Stir in the sautéed mushrooms and onions along with shredded Swiss cheese.

Assemble and bake

Pour the mixture into the prepared baking dish.

Bake for 25–30 minutes, or until the quiche is set and lightly golden on top.

Insert a knife in the center; it should come out clean.

Serve

Let the quiche cool for a few minutes before slicing.

Serve warm, at room temperature, or chilled.

Tips

Even cooking: Spread mushrooms and onions evenly in the baking dish to ensure uniform cooking.

Avoid watery quiche: Pat mushrooms dry after sautéing to prevent excess moisture from making the quiche soggy.

Check doneness: The quiche is done when the center is set and a knife inserted comes out clean.

Make ahead: Prepare in advance and refrigerate; gently reheat slices in the oven or microwave.

Non-stick tip: Use parchment paper for easier removal and cleanup.

Variations

Cheese swaps: Use Gruyère, feta, or goat cheese instead of Swiss for a different flavor profile.

Add vegetables: Spinach, zucchini, or roasted red peppers can be added for extra nutrition and color.

Herb boost: Fresh thyme, oregano, or parsley adds a Mediterranean touch.

Meat addition: Include diced ham, bacon, or cooked chicken for a heartier quiche.

Mini quiches: Bake in muffin tins for individual servings, perfect for brunch or meal prep.

Spicy twist: Add a pinch of red pepper flakes or a dash of smoked paprika for subtle heat.
