Ingredients
Mushrooms – Button, cremini, or a mix of wild mushrooms all work beautifully
Feta Cheese – Crumbled, creamy, and just the right amount of salty
Eggs – The heart of your base, giving you that fluffy, quiche-like texture
Milk or Half-and-Half – To lighten and enrich the eggs
Green Onions – For a mild, savory kick
Garlic – Always a flavor booster
Butter or Olive Oil – For sautéing the mushrooms
All-Purpose Flour – Helps give structure to the squares
Baking Powder – Just a little lift to keep things fluffy
Salt & Pepper – Season to taste
Fresh Herbs (optional) – Dill, parsley, or thyme add a fresh touch
Instructions
Sauté the Mushrooms
In a skillet over medium heat, melt butter or drizzle olive oil and cook the mushrooms until soft and browned—about 5–7 minutes. Toss in garlic and cook for another minute. Let them cool slightly.
Prep the Egg Mixture
In a large bowl, whisk together the eggs, milk, flour, baking powder, salt, and pepper until smooth.
Mix it All Together
Fold in the sautéed mushrooms, crumbled feta, and chopped green onions (and herbs, if using).
Bake
Pour the mixture into a greased 9×13-inch baking dish. Bake at 350°F (175°C) for about 30–35 minutes, or until the center is set and the top is golden.
Cool & Slice
Let cool for a few minutes before slicing into squares. Serve warm or at room temp.
Serving Suggestions
- With a Side Salad: A light arugula or spinach salad with vinaigrette is perfect.
- With Toast or Croissants: Brunch it up!
- Drizzle of Hot Sauce or Pesto: Adds a flavorful punch.
- Add Bacon or Spinach: Make it your own!
Storage
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat gently in the microwave or oven. You can also freeze slices for up to 2 months.

FAQs
1. Can I use other cheeses instead of feta?
Yes! Try goat cheese, ricotta salata, or shredded cheddar.
2. Can I add spinach or other veggies?
Absolutely—just sauté and drain excess moisture before adding.
3. Can I make these ahead of time?
Yes, they reheat beautifully. Bake, cool, and store covered in the fridge.
4. Can I freeze brunch squares?
Yes—wrap individually and freeze for up to 2 months.
5. Can I make it crustless?
It’s already crustless! But you could pour the filling into a pie crust for a quiche vibe.
6. Can I make it dairy-free?
Try dairy-free feta and milk alternatives like oat or almond milk.
7. Can I add meat?
Sure! Cooked bacon, sausage, or diced ham all work well.
8. Do I need to sauté the mushrooms first?
Yes—otherwise they’ll release too much moisture while baking.
9. Can I use dried herbs?
Yes, just use about 1/3 of the amount compared to fresh.
10. What’s the texture like?
Light, tender, and slightly custardy—think mini crustless quiche meets savory bar!
