These cheesy spinach puff pastry squares are quick, flaky, and perfect for appetizers or easy weeknight sides. They bake up golden with a creamy spinach-cheese center—no fuss, no fancy tools. Tested twice; best baking texture at 20 minutes for even rise and crisp edges.

Ingredients

(US measures + metric)

• 1 sheet puff pastry, thawed (about 8.5 oz / 240 g)
• 1 cup frozen chopped spinach, thawed and squeezed dry (150 g)
• 4 oz cream cheese, softened (113 g)
• 1/2 cup shredded mozzarella (55 g)
• 1/4 cup grated Parmesan (optional)
• 1 garlic clove, minced
• 1 egg, beaten (for brushing)
• Pinch of salt and black pepper

Swaps & Notes

Step-by-Step Instructions

1. Prep the pastry. Heat oven to 400°F (204°C). Line a baking sheet with parchment. Unfold puff pastry and cut into 12 even squares.
2. Make the cheesy spinach filling. Mix spinach, cream cheese, mozzarella, Parmesan (if using), garlic, salt, and pepper until smooth. Scoop 1 tablespoon onto each square.
3. Bake. Brush edges with egg wash. Bake 18–20 minutes until golden and puffy. Cool 5 minutes before serving.

Pro Tips & Variations

• Fully dry the spinach—extra moisture keeps pastry from rising.
• Keep puff pastry cold; warm dough loses its flakiness.
• Add spice: crushed red pepper or smoked paprika.
• Make mini versions by cutting pastry into 24 small squares.
• Add mushrooms or caramelized onions for a richer bite.
• For lighter filling: swap half the cream cheese for Greek yogurt.

Serving Suggestions

• Serve with marinara, ranch, or garlic yogurt dip.
• Pair with salads, soups, or charcuterie-style boards.
• Great warm appetizers for holidays, game nights, or brunch.

Storage & Reheating

Refrigerate: Up to 3 days in an airtight container.
Freeze: Freeze baked squares up to 2 months; reheat from frozen.
Reheat: 350°F (177°C) for 6–8 minutes (180°C).
Food safety: Keep chilled appetizers under 2 hours at room temperature.

Troubleshooting

• Pastry not puffing: Dough warmed too long—chill 10 minutes before baking.
• Soggy bottom: Spinach wasn’t fully squeezed dry.
• Cheese leaking out: Use only 1 tbsp filling and keep edges clean.

FAQs

Q1: Can I use fresh spinach?

A2: Yes. Assemble, freeze on a tray, then transfer to a bag. Bake from frozen.

Q3: Can I use different cheeses?
A3: Yes—cheddar, Monterey Jack, or feta all work with the same measurements.
