Ingredients You’ll Need
The magic of this Feta & Mushroom Brunch Squares Recipe comes from a handful of simple, fresh ingredients that each add their own special touch. From the buttery puff pastry that provides a flaky base to the herbs and cheeses that uplift the savory filling, every component is essential to achieve the perfect balance of flavors and textures.
- Puff pastry sheet (thawed): This flaky, buttery base creates the perfect crust that’s crisp yet tender.
- Olive oil (1 tablespoon): Adds a lovely richness and helps soften the vegetables while bringing out their natural flavors.
- Small onion (finely chopped): Provides sweetness and depth to the filling, softening beautifully as it cooks.
- Mushrooms (2 cups, sliced): Impart an earthy, hearty dimension that pairs wonderfully with cheese.
- Garlic (2 cloves, minced): Offers a fragrant punch that wakes up the entire dish.
- Dried thyme or oregano (1 teaspoon): These herbs add an aromatic, Mediterranean note.
- Salt (1/2 teaspoon) and black pepper (1/4 teaspoon): Essential for seasoning and balancing the filling perfectly.
- Feta cheese (4 oz, crumbled): Delivers tangy creaminess that contrasts beautifully with the mushrooms.
- Mozzarella or Swiss cheese (1/2 cup, shredded): Melts to provide gooey richness and a mild counterpoint to the feta.
- Eggs (2 large): Bind the filling and add a custardy texture when baked with cream.
- Heavy cream or half-and-half (1/3 cup): Adds moisture and richness to create the perfect set filling.
- Chopped parsley (1 tablespoon, optional): A fresh garnish that brightens the presentation and taste.
How to Make Feta & Mushroom Brunch Squares Recipe
Step 1: Prepare the Puff Pastry Base
Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze. Gently roll out the thawed puff pastry sheet to even out any folds and place it on the baking sheet. Using a sharp knife, lightly score a 1/2-inch border around the edges of the pastry—this will help the filling stay put while allowing the edges to puff up gloriously, creating a beautiful frame for your brunch squares. Be sure not to cut all the way through.
Step 2: Sauté the Vegetables and Seasonings
Heat olive oil in a skillet over medium heat. Add the finely chopped onion and cook until softened, which takes about 2 minutes. Next, toss in your sliced mushrooms, minced garlic, dried herbs, salt, and pepper. Sauté this mixture for 6 to 8 minutes until the mushrooms turn a gorgeous golden brown and any excess moisture has evaporated. This step is crucial because it concentrates the flavors and prevents sogginess in your final squares. Remove the skillet from heat and let the mixture cool slightly.
Step 3: Mix the Filling and Assemble
In a mixing bowl, whisk together the eggs and cream until smooth and well combined—this creates a luscious custard to hold everything together. Spread the sautéed mushroom mixture evenly inside the scored border of your puff pastry. Sprinkle crumbled feta and shredded mozzarella on top, distributing the cheeses evenly for each bite to have that perfect cheesy surprise. Finally, gently pour the egg and cream mixture over the filling, allowing it to seep into the spaces without overflowing the border.
Step 4: Bake Until Golden and Set
Place the assembled brunch squares into your preheated oven and bake for 20 to 25 minutes. Keep an eye out for a beautifully golden and puffed pastry edge, with the filling fully set and slightly puffed. Once baked, remove from the oven and if desired, sprinkle with fresh chopped parsley for a burst of bright color and flavor. Let the squares cool for a few minutes before slicing them into nine generous portions and serving warm.
How to Serve Feta & Mushroom Brunch Squares Recipe
Garnishes
Adding fresh parsley is a classic choice that brings a pop of green and a fresh herbal note, perfectly balancing the richness. You could also sprinkle a little cracked black pepper or even a dash of smoked paprika for a subtle smoky undertone. For extra flair, add a handful of microgreens or a drizzle of high-quality extra virgin olive oil right before serving.
Side Dishes
Complement your brunch squares with a light, refreshing salad—try a crisp arugula and cherry tomato salad with a lemon vinaigrette. A side of roasted asparagus or sautéed greens like spinach or kale also pairs wonderfully, adding vibrant color and nutrients to round out your meal. For a more indulgent spread, serve alongside fresh fruit or a dollop of creamy yogurt.
Creative Ways to Present
For a brunch party, serve these squares on a wooden board or a beautiful platter, garnished with fresh herbs to invite everyone to dig in. Stack smaller bites on tiered trays for a stunning display or arrange them with colorful veggies and dips for a Mediterranean-inspired brunch spread. You can even customize individual portions by adding dollops of pesto or sun-dried tomato tapenade for a personal touch.
Make Ahead and Storage
Storing Leftovers
After enjoying your delicious Feta & Mushroom Brunch Squares Recipe, don’t worry if you have leftovers. Store them tightly covered in an airtight container in the refrigerator for up to 3 days. The pastry will keep a lovely texture, and the flavors tend to develop even more after a day.
Freezing
If you want to make this recipe for future brunches, the squares freeze beautifully. Simply let them cool completely, then wrap individual squares or the whole pan tightly with plastic wrap and aluminum foil. Freeze for up to 2 months. This way, you always have a delicious savory snack ready to thaw and enjoy.
Reheating
To reheat, place the squares on a baking sheet and warm them in a preheated oven at 350°F (175°C) for 10 to 15 minutes or until heated through and crisped back up. Avoid microwaving if possible, as it can make the pastry soggy. Reheated this way, the squares taste almost as good as freshly baked.
FAQs
Can I use fresh herbs instead of dried thyme or oregano?
Absolutely! Fresh herbs like thyme or oregano can add a wonderful brightness and a more delicate aroma. Use about a tablespoon of chopped fresh herbs in place of the dried for best results, stirring them in during the last minute of sautéing to preserve their flavor.
Is there a way to make the recipe gluten-free?
Yes! Swap the regular puff pastry for a gluten-free version available in many stores or make your own gluten-free puff pastry at home. Be aware that texture might differ slightly, but the filling’s flavors will remain just as delicious.
Can I add other vegetables to the filling?
Definitely. Spinach, sun-dried tomatoes, or roasted peppers are excellent additions that complement the mushrooms and cheese beautifully. Just make sure any added veggies are cooked and drained well to avoid excess moisture in the tart.
What can I substitute for the feta cheese?
If you’re not a fan of feta, goat cheese is a fantastic alternative that provides similar tanginess and creaminess with a slightly different flavor profile. Ricotta can also be used for a milder, creamier texture but might slightly change the overall taste.
Can this dish be made vegan?
You can adapt the recipe by using vegan puff pastry and substituting dairy cheeses with plant-based alternatives like almond or cashew-based cheeses. For the egg and cream, try a silken tofu mixture or chickpea flour batter to replicate the custardy texture.

Ingredients
Pastry Base
- 1 sheet puff pastry (thawed)
Mushroom Filling
- 1 tablespoon olive oil
- 1 small onion (finely chopped)
- 2 cups mushrooms (sliced)
- 2 cloves garlic (minced)
- 1 teaspoon dried thyme or oregano
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Cheeses & Egg Mixture
- 4 oz feta cheese (crumbled)
- 1/2 cup shredded mozzarella or Swiss cheese
- 2 large eggs
- 1/3 cup heavy cream or half-and-half
Garnish
- 1 tablespoon chopped parsley for garnish (optional)
Instructions
- Preheat and Prepare Pastry: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper, then roll out the thawed puff pastry slightly and place it on the sheet. Using a knife, carefully score a 1/2-inch border around the edges without cutting all the way through; this will help the edges puff up during baking.
- Sauté Vegetables: Heat olive oil in a skillet over medium heat. Add the finely chopped onion and cook for about 2 minutes until softened. Stir in the sliced mushrooms, minced garlic, dried thyme or oregano, salt, and black pepper. Continue sautéing for 6 to 8 minutes until the mushrooms release their moisture, become golden, and the mixture is no longer watery. Remove from heat and let it cool slightly.
- Mix Egg Mixture: In a bowl, whisk together the two large eggs and the heavy cream or half-and-half until combined and smooth.
- Assemble the Squares: Spread the cooled mushroom and onion mixture evenly inside the scored border on the puff pastry. Sprinkle the crumbled feta and shredded mozzarella (or Swiss) cheese evenly over the mushrooms. Carefully pour the egg and cream mixture over the filling, ensuring it is evenly distributed.
- Bake: Place the baking sheet in the preheated oven and bake for 20 to 25 minutes or until the puff pastry is golden, puffed, and the egg filling is fully set and cooked through.
- Garnish and Serve: Remove from the oven and, if desired, sprinkle chopped parsley on top for a fresh finish. Cut into squares and serve warm.
Notes
- The mushroom mixture can be prepared a day in advance to save time on the day of serving; just assemble and bake when ready.
- For additional flavor and variety, consider adding sun-dried tomatoes or fresh spinach to the mushroom sauté.
