Healthy Sweet Onion Puff Pastry Tart Recipe

Sweet Onion Puff Pastry Tart is a simple but exquisite lunch or brunch tart. Cut it into appetizer squares. This dish is great with Vidalia, Maui, or generic sweet onions.

– 1/2 cup mayonnaise – 1/4 tsp onion salt – fresh cracked black pepper, to taste – 3/4 cup shredded sharp white cheddar cheese – 1 sheet frozen puff pastry – 1 medium sweet onion, peeled and sliced into very thin rings, I use my mandoline slicer set at 1/8 inch – 1 Tbsp olive oil, for brushing – a few sprigs fresh thyme for serving



Preheat oven to 400F and line a large baking sheet with parchment. Mayo, onion salt, pepper, and cheese should be mixed. Set aside.

Step 1

Step 2

Carefully roll out the puff pastry to 2 inches longer and 1 inch broader. You want to thin puff pastry, which is previously rolled. 

Step 3

Create a frame by scoring the pastry's outside 1/2 inch from the edge with a sharp knife. Pierce the pastry numerous times inside your frame with a fork.

Step 4

Oven-bake puff pastry for 10 minutes. OK middle puffing. Fork-deflate the dough's middle after baking, then spread mayo over the rectangle inside the scored lines. 

Step 5

Brush liberally with olive oil and top with thinly sliced onion (you may not need all your slices, depending on onion size).

Step 6

Return to the oven and bake for 25–30 minutes until the pastry is golden brown. Add fresh thyme leaves to the tart and serve warm.
