Preparation Techniques
3.1. Cooking Methods: Dish or Muffin Tin?
When making Feta & Mushroom Brunch Squares, the cooking method you choose can influence both texture and presentation. The two most popular options are:
-
Baking in a Casserole Dish 🥘 – Ideal for serving a crowd or cutting uniform squares. This method produces a soft, custard-like center with a slightly crisp top. It’s perfect if you prefer a traditional brunch casserole feel.
-
Using Muffin Tins 🧁 – Great for portion control and easy grab-and-go servings. Each portion bakes evenly, giving you golden edges and a firmer texture. This method is ideal for meal prep or kid-friendly options.
Cooking temperature matters, too. A steady bake at 350°F (175°C) allows the eggs to set without drying out. Baking for 25–30 minutes ensures the center is cooked through while maintaining moisture and softness. For muffin tins, reduce bake time to 18–22 minutes due to the smaller portions.
3.2. Step-by-Step Guide: From Prep to Perfection
Making Feta & Mushroom Brunch Squares is straightforward with a little prep. Here’s a simple guide:
-
Preheat oven to 350°F (175°C) – This ensures even cooking from the start.
-
Sauté your vegetables – Cook onions and mushrooms in a bit of olive oil until softened and browned. This step builds flavor and reduces moisture.
-
Whisk the eggs – Beat eggs with a splash of milk or cream, then season with salt, pepper, and your chosen herbs or spices.
-
Mix the base – Combine sautéed veggies with crumbled feta and any extras like spinach or chopped herbs.
-
Pour into your dish – Lightly grease your casserole dish or muffin tin, pour in the mixture, and smooth the top.
-
Bake until set – For casserole dishes, bake 25–30 minutes; for muffin tins, check at 18 minutes.
-
Cool and serve – Let them rest a few minutes before slicing or unmolding for cleaner cuts.
Pro Tips:
-
Avoid watery squares by fully cooking mushrooms and draining any excess liquid.
-
For fluffier texture, let the egg mixture sit for 5 minutes before baking.
-
Don’t overbake, or the eggs can become rubbery. The center should jiggle slightly but not look wet.
3.3. Make-Ahead and Storage: Save Time Without Sacrificing Flavor
These brunch squares were made for planning ahead. Here’s how to keep them fresh and flavorful:
-
Make-Ahead Tips – Assemble everything the night before, store it covered in the fridge, and bake in the morning. Or bake fully, cool, and store for quick meals later in the week.
-
Storage – Keep in an airtight container in the fridge for up to 4 days. Reheat in the microwave or toaster oven until warm.
-
Freezing Options – Wrap individual squares tightly in foil or plastic, then freeze in a zip-top bag. They’ll stay good for up to 2 months.
-
Reheating – For best results, reheat in the oven at 300°F (150°C) for 10–12 minutes. This helps retain the texture and avoids sogginess.
These squares are just as good the next day, making them ideal for busy mornings or leisurely weekend brunches.

Are there dairy-free alternatives to feta cheese?
Absolutely. Many brands offer plant-based feta substitutes made from tofu, almonds, or cashews. These dairy-free options provide a similar tangy flavor and crumble texture, making the dish suitable for vegan and lactose-intolerant diets.
Can I freeze the brunch squares?

What are the best mushrooms to use?
Cremini or baby bella mushrooms are top choices. They offer rich umami flavor and a meaty texture that holds up well when baked. You can also use white button mushrooms for a milder taste or mix in shiitake for added depth.
How do I prevent the squares from becoming soggy?
The key is proper vegetable prep. Always sauté the mushrooms and onions thoroughly before adding them to the egg mixture. Cook until most moisture is released and evaporated. This ensures your brunch squares stay firm, not watery.
