How to Make Spring Onion & Mushroom Frittata
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Step 2: Cook the Vegetables
Heat olive oil or butter in an oven-safe skillet over medium heat.
Add the sliced mushrooms and cook for about 5–6 minutes until they release their moisture and become golden.
Stir in the chopped spring onions and cook for another 2 minutes until fragrant.
Step 3: Prepare the Egg Mixture
In a mixing bowl, whisk together:
- Eggs
- Milk or cream
- Salt
- Black pepper
Stir in half of the shredded cheese.
Step 4: Combine and Cook
Pour the egg mixture over the sautéed mushrooms and onions in the skillet.
Let it cook undisturbed for 2–3 minutes until the edges start to set.
Sprinkle the remaining cheese over the top.
Step 5: Bake the Frittata
Transfer the skillet to the oven and bake for 12–15 minutes, or until the center is set and the top is lightly golden.
The aroma filling the kitchen at this point is absolutely irresistible!
Step 6: Garnish and Serve
Remove from the oven and let the frittata rest for 5 minutes before slicing.
Top with fresh parsley or chives and serve warm.

Tips for the Perfect Frittata
Don’t Overcook the Eggs
Eggs continue cooking even after leaving the oven. Remove the frittata once the center is just set.
Use an Oven-Safe Skillet
A cast-iron skillet distributes heat evenly and creates the best texture.
Cook the Vegetables First
Vegetables release moisture, so sautéing them first prevents a watery frittata.
Let It Rest Before Slicing
Allowing the frittata to rest helps it firm up and slice cleanly.
Storage Instructions
Refrigerator
Store leftovers in an airtight container for up to 4 days.
Reheating
Warm slices in the oven at 325°F for 5–8 minutes or microwave briefly.
Freezing
Frittata slices can be frozen for up to 2 months. Wrap tightly and thaw overnight before reheating.
