Ingredients

• 1 large onion, thinly sliced
• 2 tablespoons butter
• 1 cup grated cheddar cheese
• 1/2 cup grated parmesan cheese
• 1/4 cup all-purpose flour
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon paprika
• 2 cloves garlic, minced
• 1 cup puff pastry, thawed
• 1 egg, beaten (for brushing pastry)
• Fresh parsley or chives, chopped (for garnish)

Instructions

1. Step 1: Preheat your oven to 400°F (200°C). In a large skillet, melt the butter over medium heat. Add the sliced onions and cook until they are caramelized and golden brown, stirring occasionally. This should take about 20-25 minutes.
2. Step 2: In a large bowl, combine the grated cheese, flour, salt, pepper, and paprika. Mix well to combine. Add the cooked onions, garlic, and chopped parsley to the bowl and mix until the onions are evenly coated with the cheese mixture.
3. Step 3: Roll out the puff pastry on a lightly floured surface to a thickness of about 1/8 inch. Cut the pastry into 12 equal squares, each about 3 inches per side. Spoon a small amount of the onion mixture onto one half of each square, leaving a 1/2 inch border around the edges. Brush the edges with the beaten egg and fold the other half of the pastry square over the filling to form a triangle. Press the edges to seal.
4. Step 4: Place the onion squares on a baking sheet lined with parchment paper and brush the tops with the remaining egg. Bake the squares in the preheated oven for 20-25 minutes, or until they are golden brown and puffed. Serve warm and enjoy!

Handy Tips

• To caramelize the onions more quickly, you can add a pinch of salt to the skillet and cook the onions over medium-high heat, stirring frequently.
• If you don’t have puff pastry, you can substitute it with pie crust or even croissant dough.
• To make the onion squares more substantial, you can add some diced ham or bacon to the onion mixture.

Heat Control

To achieve the perfect golden brown color on the onion squares, it’s essential to keep an eye on the heat. Make sure the oven is preheated to the correct temperature, and check the squares after 15 minutes of baking. If they are not yet golden brown, continue to bake in 5-minute increments until they are perfectly cooked.

Crunch Factor

The key to a perfect onion square is achieving the right balance of crunch and softness. To get the crunch factor just right, make sure to bake the squares until they are golden brown and puffed. You can also try brushing the tops with a little bit of water and then baking them for an additional 2-3 minutes to get a crisper texture.

Pro Kitchen Tricks

• To make the onion squares more efficient to make, you can prepare the onion mixture and the pastry squares ahead of time and store them in the fridge for up to a day.
• To get the perfect triangle shape, make sure to press the edges of the pastry firmly to seal and use a sharp knife to trim any excess pastry.
• To add an extra layer of flavor, you can brush the onion squares with a little bit of olive oil or butter before baking.

Storage Tips

• The onion squares can be stored in an airtight container in the fridge for up to 3 days.
• To freeze the onion squares, place them on a baking sheet lined with parchment paper and freeze until solid. Then, transfer the frozen squares to a freezer-safe bag or container and store for up to 2 months.
• To reheat the onion squares, simply bake them in the oven at 350°F (180°C) for 10-15 minutes, or until warmed through.

Gift Packaging Ideas

If you want to give the onion squares as a gift, you can package them in a decorative tin or jar and tie with a ribbon. You can also include a card with the recipe and some serving suggestions. Another idea is to package the onion squares in a paper cone or bag and tie with a twine or ribbon.

Flavor Variations

• Instead of using cheddar and parmesan cheese, you can try using other combinations like mozzarella and feta or goat cheese and cheddar.
• You can also add some diced herbs like parsley, rosemary, or thyme to the onion mixture for extra flavor.
• For a spicy twist, you can add some diced jalapenos or red pepper flakes to the onion mixture.

Troubleshooting

• If the onion squares are not browning evenly, you can try rotating the baking sheet halfway through the baking time.
• If the pastry is too sticky, you can try dusting it with a little bit of flour or cornstarch.
• If the onion squares are too crispy, you can try baking them for a shorter amount of time or covering them with foil to prevent over-browning.

FAQs

• Can I freeze the onion squares? Yes, you can freeze the onion squares for up to 2 months. Simply place them on a baking sheet lined with parchment paper and freeze until solid. Then, transfer the frozen squares to a freezer-safe bag or container and store in the freezer.
