This tart is seriously satisfying.
It's loaded with delicious and filling vegetables, smoked chicken sausage, and a good amount of Emmental (aka Emmenthal or Emmentaler or Emmenthaler) cheese. Sigh, I love cheese. It is also really easy to put together, especially once the ingredients are prepped and ready to add to the puff pastry.
I find that using a mandoline to slice the potatoes is my favourite method to get uniform thin pieces, but a sharp knife and a steady hand will work just as well. Baking the raw potato on the puff pastry does not result in a tender cooked potato, so parboiling the potato slices for a few minutes ensures that the you are not eating crunchy, undercooked potatoes in the end.
The roasted broccoli ends up crisp and tender with those tasty brown tips and the red onions add a little sweetness. The mild Italian chicken sausage adds the meaty, salty, slightly spicy component to this dish, and the slightly nutty and sweet Emmental cheese melts wonderfully.
The crispy, flaky, golden-brown puff pastry crust ties it all together making it a wonderful meal or appetizer since you can slice it into as many pieces as you like.
All the ingredients! Amounts in "Ingredients" below. Preheat the oven to 400 F. Line a baking sheet with parchment paper. Parboil potato slices until edges are tender and middle is slightly undercooked.
In a large bowl, toss together broccoli, onions, garlic, dried rosemary, salt, and pepper.
Roll out puff pastry to 10x10 inches. Sprinkle 1/2 of the cheese and then layer potatoes on top.
Top with broccoli mixture, sausage, and remaining cheese.
Bake for 20-25 minutes until the puff pastry is golden-brown.
Serve immediately or warm. Enjoy!
