• 1 ½ tablespoons active dry yeast
• 6 ½ cups bread flour
• ½ teaspoon dried marjoram
• 2 tablespoons water, or as needed
• 2 ½ cups warm water
• 1 tablespoon vegetable oil, or as needed
• 1 tablespoon coarse kosher salt
• 1 ½ tablespoons minced fresh rosemary

• 2 tablespoons all-purpose flour, or as needed (Optional)

Recipe Instructions

Step 1

Preheat oven to 375 degrees F (190 degrees C).

Step 2

Heat 3/4 cup vegetable oil in a large skillet over medium heat; cook and stir onions until golden brown and very tender, 20 to 30 minutes. Add garlic and butter; cook and stir until butter is melted and garlic is fragrant, 5 to 10 minutes. Remove skillet from heat and cool onion mixture to room temperature.

Step 3

Combine warm water and olive oil in the bowl of a stand mixer.

Step 4

Combine bread flour, white sugar, yeast, and kosher salt in a bowl; sift into the bowl with oil and water. Attach dough hook to mixer; add parsley, rosemary, and marjoram and mix on medium speed until dough holds together and is no longer sticky, 5 to 8 minutes.

Step 5

Turn dough onto a floured work surface and knead, adding flour if needed, until dough becomes somewhat firm. Divide dough into six 10-ounce portions.

Step 6

Roll each portion of dough into a 12-inch rectangle, dusting with flour if sticky. Fill each rectangle with equal quantities onion mixture and 1/4 cup blue cheese. Roll each rectangle into an oval baguette-shape stromboli, pinching the edges to close.

Step 7

Grease 2 baking sheets with 1 tablespoon vegetable oil.

Step 8

Generously brush the bottoms of each stromboli with water and transfer to the prepared baking sheets; cover with plastic wrap. Allow stromboli to rise for 2 hours.

Step 9

Bake in the preheated oven until golden brown, rotating the stromboli as needed for even browning, 45 minutes to 1 hour.
