- 8 cherry tomatoes, halved

Step-by-Step Instructions
Step 1: Preparing the Pastry
Roll out the puff pastry and cut it into rectangles. Fold the corners of the upper third to create an envelope shape. Fold up the edges of the long sides to create a border. Spread tomato sauce inside the pastry base evenly.
Step 2: Cooking the Steak & Assembling
Season the steaks with salt and pepper. Heat a pan over medium-high heat and sear the steaks for 2 minutes per side until browned. Place the seared steaks over the tomato sauce in the pastry. Sprinkle shredded mozzarella on top and add mini mozzarella balls. Fold the bottom half of the dough over the steak, then fold the top down to form an envelope. Press the edges closed using a fork.
Step 3: Decorating & Baking
Cut small heart shapes from the remaining dough and place them on top. Transfer everything to a parchment-lined baking sheet. Beat the egg and brush it over the pastry for a golden finish. Bake in a preheated oven at 350°F (175°C) for 25 minutes or until golden brown.

Expert Tips & Tricks
Best Practices
Chill your puff pastry before baking to prevent shrinking. Let the steak rest after browning to lock in juices before baking. Brush with egg wash generously for a shiny golden crust.
Common Mistakes
Overcooking the steak can lead to dryness, so sear it lightly since it will cook further in the oven. Ensure the edges are sealed well to prevent filling leaks. Don’t skip the egg wash, as it gives the pastry its signature golden shine.
Time-Saving Tips
Use pre-cooked steak slices for an even quicker prep. Prepare the pastries ahead of time and refrigerate until ready to bake.
Serving Suggestions
Pairings
Serve with a fresh arugula salad for a light contrast. Pair with roasted vegetables like asparagus or bell peppers.
Presentation Ideas
Plate with a drizzle of balsamic glaze for an elegant touch. Sprinkle with fresh basil leaves to add color and flavor.
Beverage Pairings
Red wine, like a smooth Merlot or Cabernet Sauvignon, pairs beautifully. For a non-alcoholic option, serve with a sparkling berry mocktail.
Storage & Reheating
Leftover Storage
Store in an airtight container in the fridge for up to 3 days. Freeze uncooked assembled pastries for up to 1 month.
Reheating Methods
Bake at 350°F for 10 minutes to regain crispiness. Heat in an air fryer at 375°F for 5-7 minutes for a quick reheat. Avoid microwaving, as it can make the pastry soggy.
Frequently Asked Questions
Substitutions & Adjustments
Can I make this vegetarian? Yes, swap the steak for grilled portobello mushrooms or eggplant slices.
Can I use store-bought dough? Absolutely, frozen puff pastry sheets work perfectly for convenience.
What other cheeses work well? Try provolone, gruyère, or even blue cheese for a bolder flavor.
Troubleshooting
Why is my pastry not browning? Make sure to brush evenly with egg wash and bake at the correct temperature.
My filling leaked out – what went wrong? Ensure you’ve sealed the edges tightly and don’t overfill the pastry.
Variations & Customizations
Dietary Adaptations
Use dairy-free cheese for a lactose-free version. Substitute with gluten-free pastry for a gluten-sensitive option.
Flavor Twists
Add a sprinkle of red pepper flakes for a spicy kick. Incorporate caramelized onions for added sweetness and depth.
