These savory croffles are made with puff pastry, bacon, and cheese. I did a side-by-side comparison of croffles made with puffy pastry and crescent rolls, and the puff pastry was much flakier. See the blog post for the full breakdown with pictures.
First, make sure your puff pastry is defrosted according to the package instructions.
Chop the bacon into small ½-inch pieces
Add the bacon to a nonstick pan over medium heat. Cook for 5-10 minutes until all the fat is rendered out and the bacon is brown and crispy.
Preheat your waffle iron.
Cut the sheet of puff pastry into 4 triangles.
For each triangle, add some cheese and bacon. Roll from the wide end to the short end until you have a croissant. Place the croissant into the waffle iron.
Place the croissant into the waffle iron and cook until it's golden brown. Enjoy!
Notes
Other topping sides:
Ricotta cheese and spinach
Cheese, corn, and mayo. I have a recipe here for Chinese corn buns and you can use the filling there.
