Equipment

  • Skillet
  • Wooden Spoon
  • Chef's Knife
  • Measuring Spoon tablespoon sized
  • Muffin Pan
  • Pastry Brush

Ingredients
  

  • 1 sheet frozen puff pastry defrosted
  • ½ tablespoon unsalted butter
  • 5 ounces frozen spinach half of the bag
  • 4 ounces cream cheese cubed
  • 2 tablespoon pesto
  • 1 teaspoon lemon juice
  • ½ teaspoon Dijon mustard
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon ground oregano
  • ¼ teaspoon chili powder
  • pinch salt optional - for taste
  • 1 count egg for an egg wash

Instructions

  • Take your frozen puff pastry sheet and let it thaw on the counter until soft and pliable.
  • Melt the butter in a skillet over medium heat. Add the frozen spinach and cook for a few minutes until it begins to soften.
  • Add in your cubed cream cheese, pesto, and lemon juice and continue to cook until everything is melted and combined.
  • Season the spinach mixture with the Dijon mustard + listed seasonings, adding a pinch of salt to taste if needed. Let the mix cool while you preheat the oven to 400°F.
  • Cut the thawed puff pastry into 9 even-sized squares. Prepare a cupcake pan with non-stick cooking spray.
  • Place your puff pastry squares into the cupcake pan inserts and then top each square with about 1 ½ tbsp. of spinach mixture. This is about 30 grams of filling per puff.
    Fold the pastry corners over the creamed spinach.
  • Take the egg and whisk it with a bit of water to create an egg wash, then brush the tops of the spinach puffs with the egg wash.
  • Bake at 400°F for 16-18 minutes, until the spinach puffs are golden brown. Serve topped with fresh parsley and a hint of flaky salt. Enjoy!

Notes

Make Ahead Instructions:
These can be served fresh out of the oven, or room temperature. 
To make ahead, prepare the filling and store in the refrigerator. When you're ready to bake, fill each puff pastry, brush with egg wash, and bake.
 
Storage Instructions:
Store these in a sealed container in the refrigerator. Heat in a toaster oven or air fryer to get them crispy again. These will last up to 5 days.
