Common Questions About This Recipe

→ How do I caramelize onions properly?

Cook onions gently over medium-low heat with a mix of butter and olive oil, stirring now and then for 25 to 30 minutes until they turn soft and golden, bringing out their natural sweet flavor.

→ Can I use other types of mushrooms?

Definitely. Cremini and button mushrooms are great, but shiitake or portobello add richer taste after cooking until they’re dry and brown.

→ What cheese is best for this braid?

Gruyère and mozzarella melt beautifully and blend nicely with the onion and mushroom flavors, giving a creamy texture.

→ Why add balsamic vinegar to the onions?

Balsamic vinegar brings out the sweetness of the caramelized onions and adds a light tang that lifts the overall taste.

→ Can I prepare this braid in advance?

Yes, you can put the braid together before and keep it in the fridge until baking. Just brush with egg wash and bake it when you want fresh, crispy pastry.

Ingredients You’ll Need

→ Filling

01 1 tablespoon unsalted butter
02 2 tablespoons olive oil
03 1 teaspoon fresh thyme leaves, plus some extra to sprinkle
04 Black pepper, as you like it
05 Salt, to taste
06 2 cloves garlic, finely chopped
07 8 ounces sliced mushrooms (use button or cremini)
08 2 large yellow onions, sliced thin
09 1 tablespoon balsamic vinegar

→ Assembly

10 1 sheet frozen puff pastry, thawed
11 1 cup shredded mozzarella or Gruyère cheese
12 1 large egg, beaten
13 1 tablespoon sesame seeds if you want

How to Make It

Step 01

Start by heating the butter and olive oil in a big pan over medium-low heat. Toss in the onions and cook gently, stirring now and then, for about 25 to 30 minutes until they're soft and golden brown.

Step 02

Add thyme, balsamic vinegar, salt, and pepper to the onions. Keep cooking for 2 more minutes, then take the pan off the heat and let it cool down a bit.

Step 03

Use the same pan. Add a little olive oil if it looks dry. Cook the mushrooms on medium-high heat for 5 to 7 minutes until they're browned and all the liquid is gone.

Step 04

Stir in the garlic with the mushrooms and cook just for 30 seconds. Then, mix the mushroom-garlic in with the caramelized onions. Let the whole filling cool off some.

Step 05

Preheat your oven to 400°F. Lay the thawed puff pastry out on parchment paper and roll it flat.

Step 06

Put the pastry so the long edge is facing you. Spread the onion-mushroom mix in a line down the middle third of the dough. Sprinkle the cheese over the filling evenly.

Step 07

Cut diagonal strips about an inch wide along both sides of the pastry. Fold the strips over the filling one by one, alternating sides, to make a braid shape.

Step 08

Brush the braid top with the beaten egg. If you want, toss some sesame seeds on top as a finishing touch.

Step 09

Move the braid with the parchment paper onto a baking sheet. Bake for 25 to 30 minutes until the pastry is puffed up and golden all over.

Step 10

Let it sit for 5 minutes to cool a bit. Add fresh thyme leaves on top if you like. Slice it up and serve warm.

Extra Suggestions

  1. The tastiest results happen when onions are really caramelized and the pastry stays cold before you put it together. Gruyère gives a nice nutty flavor.
