Caramelized Onion, Steak, and Blue Cheese Tarts

Submitted by Melanie B.

"I made these up using some left over grilled steak from dinner the night before. Use a leftover steak with basic seasoning...such as salt and pepper or a soy based flavor. They are a great quick crowd pleaser that lets you get away with using leftovers."

 

• Ready In: 30mins
• Ingredients: 10
• Serves: 8

ingredients

• 1 large yellow onion, peeled and thinly sliced
• 1 sheet puff pastry, thawed
• 1⁄3 cup blue cheese, crumbles
• 3⁄4 cup steak, leftover cut into small pieces
• 2 tablespoons balsamic vinegar
• 1 tablespoon olive oil
• 1 garlic clove, minced
• salt
• pepper
• 1 egg, beaten lightly with a teaspoon of water

directions

1. In a hot skillet, heat oil. Add onions and cook until brown and caramelized. Stir frequently and be careful not to burn. Add garlic and vinegar. Reduce heat to medium low and cook a few more minutes until the liquid is fully absorbed. Remove from heat.
2. Stir in meat and cheese.
3. In the meantime, use a rolling pin to seal the creases of the puff pastry. Use parchment paper on either side to keep from sticking instead of flour. Cut into squares in any size of your choice. I like to do small ones (about 4 inches or so). Curl up the edges slightly to make an edge. They do not need to be perfect however -- this dish looks its prettiest rustic style.
4. Brush the outside edge of the pastry with the egg wash.
5. Fill each pastry square the mixture.
6. Bake in a 375 degree oven for about 8-12 minutes, or until browned on the edges.
7. Enjoy!
