Caramelized Onion Flatbread with Sausage and Rosemary

onion and sausage flatbread

Yield: 6 as appetizer
Prep: 1 hour | Cook: 1 hour and 30 minutes
Total Time: 2 hours and 30 minutes


  • 2 tsp Yeast
  • ¾ cup Water, warm approximately 90 degrees
  • 3 cups All-Purpose Flour
  • 1 tbsp Salt
  • 4 tbsp Butter, unsalted Softened
Onion Marmalade:
  • 8 cups yellow onions thinly sliced (approximately 6 medium sized onions)
  • ¼ cup Extra Virgin Olive Oil
  • 1 tbsp Fresh Thyme, chopped
  • 2 tbsp Salt
  • 2 tbsp Black Pepper
Additional Ingredients:
  • 1 cup Sausage, cooked and crumbled finely (About 2 Links)
  • 3 cups Grated Cheese such as Comte and/or Cheddar (Blue Cheese also works but use sparingly)
  • 1 tbsp Rosemary Finely Chopped


Preheat oven to 350 degree

  1. Bloom the yeast in warm water until fully dissolved.
  2. In a mixer with a dough hook attachment, combine the flour, salt butter and yeast/water mixture. Mix until fully incorporated and smooth. Adjust flour/water as needed if dough appears too wet and/or too dry.
  3. Cover in a stainless bowl with Saran Wrap for at least 1 hour in a warm area. This dough can be prepared 1 day in advance and kept in the refrigerator.
Onion Marmalade:
  1. In a medium size pot heat the oil with the onions on low heat. Season the onions with salt and pepper. Cover the pot with a lid and allow onions to sweat for 10 minutes. There will be a good amount of water from the onions.
  2. Remove the lid, turn the heat up to medium and begin to cook out the liquid. This will take approximately 1 hour. Continue to stir periodically to avoid scorching. Once the onions have developed a deep golden color, remove from the heat, add the chopped thyme and cool.
  1. Lightly flour work space and roll dough approximately 1/8 in. thickness. Lightly fork the dough to prevent bubbles.
  2. Spread the Onion Marmalade evenly over the surface of the dough.
  3. Sprinkle the Onions with Sausage. Season with Rosemary. Top with Grated Cheese.
  4. Bake until golden brown on the edges for approximately 20-25 minutes. Cool for 10 minutes then slice and serve!
