One of my favorite Thanksgiving dishes is a green bean casserole. I think it’s partially because it’s one of those dishes that we only eat at Thanksgiving, so every bite really tastes like the holiday. Last year I gave the classic version of the recipe a new twist with a French onion soup style green bean casserole, complete with melty cheese on top! This year, while brainstorming my Trader Joe’s Thanksgiving short cuts series, I decided to give my green bean casserole an appetizer makeover and bake the chopped up green beans with some condensed mushroom soup inside frozen puff pastry bites (side note: Trader Joe’s Frozen Puff Pastry is some of the best, it’s made with real butter so it gets that homemade flaky crust that’s hard to achieve with many store-bought brands!). After the warm, bubbly, green bean and mushroom-flavored pastry bites come out of the oven they get topped with the best part of the dish — the crunchy fried onions. Irresistible!

Prep time: 
Cook time: 
Total time: 
Serves: 12-16 bites
  • 1 Sheet of Trader Joe's Frozen Puff Pastry
  • 1½ Fresh Green Beans
  • ½ Cup Trader Joe's Portabella Mushroom Soup
  • Trader Joe's Crispy Fried Onions
  1. Preheat oven to 400 degrees.
  2. Thaw a sheet of Trader Joe's Frozen Puff Pastry and cut into 2x2" squares. Press into a mini muffin tin until you have 12-16 spaces filled with pastry.
  3. Roughly chop green beans into ½ pieces and transfer to a bowl. Pour the Trader Joe's Portabella Mushroom Soup over the green beans and mix with a spoon until they're well coated.
  4. Scoop about a tablespoon of the green mixture into each pastry dough lined muffin tin, repeat until all are filled.
  5. Bake the green bean bites in the oven for 20 minutes, until the puff pastry is golden brown.
  6. Remove from oven and top each green bean casserole bite with sprinkle of the Trader Joe's Crispy Fried Onions. Serve warm.
