Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

• Almond Flour: This is my absolute favorite base for gluten-free baking. It provides the essential structure and a delicate, buttery crumb that beautifully mimics traditional flour.
• Mozzarella Cheese: I highly recommend using a low-moisture option here. When melted into the dough, it provides the crucial elasticity needed to roll out a beautifully pliable pastry.
• Cream Cheese: A block of full-fat cream cheese adds incredible richness to the filling. It binds the spinach together while creating an ultra-creamy, velvety internal texture.
• Spinach: Fresh or frozen works beautifully, but ensure it is completely drained. It provides the earthy flavor base and a wonderful pop of color to the filling.
• Egg: A single large egg is essential for binding the pastry dough together perfectly. It also doubles as a simple wash to achieve that stunning, glossy golden-brown top.
• Garlic Powder: This is a simple, must-have addition for instant savory depth. It effortlessly elevates the spinach and cheese filling with a classic, aromatic flavor profile.

Common Mistakes to Avoid:

• Leaving Excess Moisture in the Spinach: Wet spinach will make the bottom crust soggy, so always squeeze out as much water as physically possible.
• Rolling the Pastry Dough Too Thin: If the dough is rolled out too thin, it will tear during assembly and cause the cheese filling to leak out.
• Skipping the Steam Vents: Forgetting to cut slits in the top pastry layer traps steam inside, which prevents the crust from becoming perfectly crisp.

Required Equipment:

• Rolling Pin: Flattens the low-carb pastry dough evenly to ensure uniform baking throughout.
• Parchment Paper: Prevents the cheese-based dough from sticking to your counter and baking sheets.
• Baking Sheet: Conducts heat evenly to give your pastry a beautifully browned bottom crust.
• Sharp Knife: Cuts precise steam vents into the top pastry layer for optimal texture.

Caleb’s Recipe Tips

• To get the flakiest crust possible, make sure your dough is slightly warm and pliable when rolling it out between the sheets of parchment paper. If it cools down too much and becomes stiff, simply pop it back into the microwave for about ten seconds to soften it up.
• Trust me, I’ve learned this the hard way: always use a kitchen towel or cheesecloth to wring out your cooked spinach until it is bone-dry. Even a little bit of hidden moisture will ruin the pastry base and leave you with a soggy bottom.
• If you want to take the savory flavor profile to the next level, try tossing a handful of crumbled feta or sharp parmesan into the filling mixture. The extra saltiness cuts through the rich cream cheese beautifully and adds amazing depth.

Storage Instructions:

Store any leftover pastry squares in an airtight container in the refrigerator for up to 4 days. For longer storage, wrap individual unbaked or baked squares tightly in plastic wrap and freeze them for up to 2 months. To preserve the signature crispy texture, always reheat your leftovers in an oven or air fryer at 350°F until warmed through; avoid the microwave, as it will make the crust soft.

Ingredients

Scale

1/2x 1x 2x 3x

• 2 cups Mozzarella Cheese, shredded (used for the pastry dough)
• 2 tbsp Cream Cheese, full-fat (used for the pastry dough)
• 1 cup Almond Flour, super-fine
• 1 Large Egg, beaten
• 1 cup Spinach, cooked, cooled, and squeezed completely dry
• 4 tbsp Cream Cheese, full-fat (used for the filling)
• ¹⁄₂ cup Mozzarella Cheese, shredded (used for the filling)
• ¹⁄₂ tsp Garlic Powder
• ¹⁄₄ tsp Salt
• ¹⁄₄ tsp Black Pepper
• 1 Egg 1 YoIk, beaten with 1 tsp water for the egg wash

Instructions

1. Preheat and Prep: Preheat your oven to 400°F (200°C) and line a large baking sheet with a piece of high-quality parchment paper.
2. Melt the Dough Base: In a large microwave-safe bowl, combine the 2 cups of shredded mozzarella and 2 tablespoons of cream cheese. Microwave on high in 30-second intervals, stirring well between each, until the cheese is completely melted and smooth.
3. Form the Pastry Dough: Add the super-fine almond flour and the beaten egg to the melted cheese mixture. Knead vigorously with your hands until a cohesive, smooth dough forms. If the dough gets too sticky, place it between two sheets of parchment paper to manage it.
4. Roll it Out: Roll the dough out between two large sheets of parchment paper into a large, even square or rectangle, roughly 1/4-inch thick. Cut the dough into equal squares.
5. Mix the Filling: In a separate medium bowl, thoroughly mix the well-drained spinach, 4 tablespoons of cream cheese, 1/2 cup of shredded mozzarella, garlic powder, salt, and black pepper until fully combined and smooth.
6. Assemble the Pastry: Divide the spinach filling evenly among the centers of half of your dough squares. Place the remaining dough squares directly over the top of the filling, and press the edges firmly together with a fork to seal completely.
7. Vent and Bake: Use a sharp knife to cut 3 parallel steam vents across the top of each assembled pastry square. Brush the tops evenly with the prepared egg wash for a beautiful glossy finish, then bake at 400°F (200°C) for 22 to 25 minutes until the pastry is puffed and deeply golden-brown. Let cool for 5 minutes before serving.
