Discover the ultimate Polish street food with these crispy, open-faced toasted baguettes. Loaded with savory sautéed mushrooms, melted cheese, and smoky kabanos, they are finished with a signature drizzle of ketchup for a perfect snack or quick dinner.
Preheat your oven to 200°C (180°C fan/gas mark 6). Place the part-baked baguettes on a baking tray and bake for 8–10 minutes until lightly crisp. Remove from the oven and let them cool completely.
In a large pan, heat 2 teaspoons of the butter and 1 teaspoon of the vegetable oil over low heat. Add the finely chopped onion and sauté for about 5 minutes until softened.
Add the chopped mushrooms to the pan and increase the heat to medium. Cook for 5–10 minutes, stirring occasionally, until the mushrooms are soft and all released liquid has completely evaporated.
Stir in the minced garlic and cook for another 1–2 minutes until fragrant. Season with salt and pepper to taste, then stir in the mayonnaise and remove the pan from the heat.
Slice the cooled baguettes in half lengthways. Place them cut-side up on the baking tray. Spread the mushroom mixture evenly over each half, then top with the chopped ham, sliced kabanos, grated cheddar, and mozzarella.
Bake for 8–10 minutes, or until the cheese has melted and turned bubbly and golden brown.
While the sandwiches bake, heat the remaining butter and oil in a small pan over medium heat. Fry the thinly sliced onions for about 5 minutes until golden and caramelized. Set aside.
Once the zapiekanki are cooked, top them with the caramelized onions, sliced dill pickles, and fresh chives. Finish with a classic zig-zag drizzle of ketchup and serve immediately.
For an authentic taste, use Polish kabanos sausages, but pepperoni or salami work well as substitutes. Ensure the mushroom liquid is fully evaporated before adding the mayonnaise to prevent the bread from getting soggy. If you prefer a milder flavor, you can substitute the cheddar with Gouda or Edam cheese.
