Ingredients in Feta & Mushroom Brunch Squares
Here’s the magic of these brunch squares—they come together with just a few basic ingredients, but the flavor is out of this world. Let’s break it down:
Feta Cheese
The creamy, tangy hero of the dish. Feta brings a sharpness that perfectly balances the rich mushrooms and buttery crust. If you love cheese, this one’s a winner.
Mushrooms
Sautéed to golden perfection, mushrooms add an earthy depth that makes the filling savory and satisfying. They soak up all those delicious flavors and add a nice texture to the filling.
Puff Pastry
The base and top of the squares. Light, flaky, and buttery, puff pastry makes everything feel extra indulgent. Plus, it’s so easy to work with—it gives you that “I’m a pro” result without the fuss.
Eggs
Eggs help bind everything together into a creamy, cohesive filling. They add richness and make the squares just the right texture—not too dry, not too soft.
Fresh Herbs
A sprinkle of fresh herbs like thyme or parsley brings brightness and an herbal aroma that perfectly complements the richness of the cheese and mushrooms. Trust me, the fresh touch makes all the difference.
Garlic
A little garlic sautéed with the mushrooms? Yes, please. It brings a subtle depth and savory kick to the filling, making it even more irresistible.
Milk or Cream
For that smooth, rich filling. A splash of milk or cream makes the mixture creamy and dreamily smooth.
Instructions
Let’s dive into the steps to create these flavor-packed squares:
Preheat Your Oven
Start by preheating your oven to 375°F (190°C). We want to make sure it’s nice and hot when we pop the squares in, so they cook up crispy and golden.
Sauté the Mushrooms
In a large skillet, heat a little olive oil over medium heat. Add the sliced mushrooms and garlic, and sauté until they’re soft and golden brown—about 5–7 minutes. This step brings out all that earthy flavor from the mushrooms and makes your kitchen smell incredible.
Make the Filling
In a bowl, whisk together the eggs, milk (or cream), and fresh herbs. Add in the sautéed mushrooms and garlic, crumbled feta, and season with salt and pepper. Stir everything together until it’s evenly combined. The mixture should be creamy and chunky, full of flavor.
Prepare the Puff Pastry
Roll out the puff pastry on a floured surface. Cut it to fit your baking dish (a 9×9 square or round dish works great). Place one layer of pastry into the dish, pressing it down gently to fit.
Assemble the Squares
Pour the feta and mushroom filling into the prepared pastry shell. Then, cover with another layer of puff pastry. Press the edges together to seal it, and cut a few slits in the top to let the steam escape while baking.
Bake to Perfection
Place the dish in the oven and bake for 25–30 minutes, or until the pastry is golden brown and puffed up. The filling should be set, and the edges of the pastry should be beautifully crisp.
Let It Cool and Serve
Remove from the oven and let it cool for a few minutes before slicing into squares. This resting time helps everything set and makes cutting easier. Then, serve warm, and enjoy!
How to Serve Feta & Mushroom Brunch Squares
These squares are fantastic on their own, but if you’re looking to elevate the meal, here are a few serving ideas:
Fresh Salads
Pair them with a light green salad, dressed with a tangy vinaigrette. The freshness of the salad balances the richness of the squares beautifully.
Roasted Veggies
Serve with some roasted vegetables—think roasted carrots, zucchini, or even brussels sprouts. The slight char adds a nice contrast to the softness of the squares.
Fresh Fruit
A side of fresh fruit, like berries or citrus, can add a burst of freshness and a touch of sweetness to complement the savory flavors.
As a Standalone
Honestly, these squares are so hearty and flavorful that they’re perfect on their own. Just garnish with a little extra fresh herbs and maybe a dollop of sour cream for a luxe touch.
Additional Tips
Here are a few extra tips to make your Feta & Mushroom Brunch Squares even more amazing:
Prep Ahead
Make the filling ahead of time and store it in the fridge. When you’re ready to bake, just assemble everything and pop it in the oven. It’ll save you time when the brunch crowd arrives.
Spice It Up
Want a bit of heat? Try adding a pinch of red pepper flakes or some chopped fresh chili to the mushroom mixture. It’ll give the squares a nice kick!
Dairy-Free Options
If you’re avoiding dairy, try substituting the feta with a dairy-free cheese and the cream with a plant-based milk. It’ll still taste fantastic!
Storage Tips
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven to keep the pastry nice and flaky.
Double the Batch
These squares freeze really well. If you’re planning ahead for a busy week, make a double batch and freeze half for later.
