• Extra-virgin olive oil – Helps sauté and develop flavor

Egg Custard

• Mozzarella or Gruyère cheese (shredded) – Adds creaminess and rich, melty texture

• Black pepper – Adds gentle heat and seasoning balance
• Kosher salt – Enhances overall flavor

How to Make 30-Minute Mushroom Swiss Egg Bake

1. Prepare the oven and ingredients

Preheat your oven to 400°F (200°C). Lightly grease ramekins or a baking dish with butter or cooking spray. Slice the mushrooms, mince the shallot, and prepare the thyme, milk, cheese, and eggs so everything is ready to go.

2. Cook the mushrooms

Heat olive oil in a skillet over medium heat. Add the shallots and cook for about 3 minutes until soft and fragrant. Add the mushrooms and salt, then cook for about 5 minutes until they release moisture and begin to brown. Stir in thyme and cook briefly until fragrant, then remove from heat.

3. Prepare the egg mixture

In a large bowl, whisk the eggs until smooth. Add milk, salt, and black pepper, then whisk again until fully combined and slightly frothy for a light texture.

4. Assemble the bake

Divide the mushroom mixture evenly into ramekins or a baking dish. Sprinkle cheese over the mushrooms, then pour the egg mixture on top, filling each container about three-quarters full.

5. Bake to perfection

Bake for 20–25 minutes, or until the eggs are set but still slightly soft in the center. Avoid overbaking to keep the texture creamy and tender.

6. Rest and serve

Let the egg bake rest for 2–3 minutes after removing from the oven. Serve warm directly in ramekins or carefully plated.

Tips for Success

• Don’t overcook the mushrooms—light browning enhances flavor without drying them out
• Use room-temperature eggs for a smoother custard texture
• Avoid overbaking to prevent rubbery eggs
• Let it rest briefly before serving for best structure
