Want to freeze these Pastry Bites with Feta and Caramelized Onion?

Follow the directions up to right before you would put it into the oven. Freeze the bites for 2-3 hours then store in a ziploc bag. When ready to cook, put them into the muffin tins and bake for 20-22 minutes. Do not bake them without the mini muffin tins, the puff pastry will flatten into pancakes making a mess.

Want to make this into a slab? Add half the sour cream and keep the puff pastry in three large triangles. Score a rectangle shape a half inch from the border and fill with the feta mixture and top with onions. Bake for 20-22 minutes. Directions can be found here.

  2. Slice the yellow onions thinly and put them in a cast iron skillet with the butter on medium-low heat.
  3. Add salt and brown sugar and cook on low for 15-20 minutes until browned, stirring every few minutes.

  4. In a bowl whisk together the feta, butter, sour cream and eggs.
  5. Unfold the puff pastry rectangles and cut each three piece sheet into 30 squares.

  1. These are my favorites at Trader Joe’s! Happy to have a homemade hack.I subbed 3% fat plain yogurt for the sour cream, and subbed sharp cheeses I had on hand instead of the feta. Tasted delicious! Only next time I will halve the butter, as the dough was soaked even after doubling the baking time. Regardless, super excited to make these again with this tweak.

  2. Recipe sounds wonderful!

    Just to clarify, do I use 3 sheets of puff pastry total (1 on top of the other), then cut the block of puff pastry sheets into 30 squares?

    1. Sorry for the confusion. The puff pastry sheet is originally folded into thirds. You’ll want to completely unfold it and cut it into 30 squares (total). I hope this clears it up for you.
