Bacon, Bleu Cheese & Caramelized Onion Tart

Lets talk fancy-ass food. Velveeta not so fancy. Little smokies- lacking some class. Cheetos? Maybe if I am in my PJ’s and slippers. All of those foods are delicious, but not really made to impress dinner guests if you are hosting an “adult” dinner party, ya know?

To me, this tart qualifies as fancy-ass. Anything with puff pastry instantly jumps up on the fancy scale, and you add bacon, caramelizedĀ onion and blue cheese and it’s definitely a dish meant to impress.

Frozen puff pastry is topped with a simple sauce made of sour cream, thyme and balsamic vinegar. Top with crispy bacon, cheese and caramelized onion, pop in the oven and you have a fast appetizer or light lunch paired with a salad.

Bacon, Blue Cheese & Caramelized Onion Tart


  • 1 medium yellow onion, sliced
  • 1 T olive oil
  • 1 tsp butter
  • 5 slices bacon, cooked and chopped
  • 3 T crumbled blue cheese
  • 1/3 cup sour cream
  • 1/8 tsp dried thyme
  • 1/2 tsp balsamic vinegar
  • salt and pepper to taste
  • 1 sheet puff pastry


  • In a large saute pan, heat the butter and olive oil over medium-high heat. Add in the onions and a big pinch of salt and cook, stirring occasionally, for 25-35 minutes until cooked down and caramelized (you may need to adjust the heat during the cooking process, so they don't burn.)
  • Preheat oven to 400 degrees, and position the rack in the upper 1/3 of the oven. In a small bowl, combine the sour cream, balsamic, and thyme with some salt and pepper.
  • On a lightly-floured work surface, roll the puff pastry out to a 14x10-inch rectangle. Cut 1/2 inch around all sides of dough, making sure not to cut completely through. Transfer to large baking sheet.
  • Spread the sour cream mixture into the center of the pastry, and to the edges. Add the caramelized onions evenly over the top, followed by the bacon and blue cheese.
  • Bake for 25-35 minutes until the pastry is golden and cooked, and the toppings are bubbly. Allow to cool slightly, and cut.
