Full Ingredients

Mushroom Topping

• 450 g mushrooms (cremini, button, or mixed), cleaned and sliced 1/8 in (3 mm)
• 3 tbsp unsalted butter (42 g)
• 1 tbsp olive oil (15 ml)
• 1 small shallot, finely chopped (30 g; optional but recommended)
• 3 garlic cloves, minced (15 g)
• 1 tsp dried marjoram (or 1/2 tsp thyme)
• 1 tsp kosher salt, divided
• 1/2 tsp freshly ground black pepper
• 1 tsp Maggi seasoning or light soy sauce (optional umami boost)

Bread and Cheese

• 1 large baguette (14–16 in / 35–40 cm; 350–400 g), split lengthwise
• 200 g Gouda or Edam, coarsely grated (about 2 cups)
• 60 g low-moisture mozzarella, grated (3/4 cup; optional for extra stretch)
• 1 tsp olive oil (for brushing bread)
• 2 tsp smooth mustard (optional, for spreading)

To Finish

• 1/2 cup ketchup (120 ml; Polish style if available)
• 1/4 cup finely chopped fresh chives (10 g)
• 1 cup thinly sliced Polish dill pickles/ogórki kiszone (100 g)

Step-by-Step Instructions

Step 1: Preheat and set up the oven

Position a rack about 6 inches (15 cm) from your broiler element. Heat the oven to 475°F (245°C). Line a large sheet pan with parchment or foil for easy cleanup.

Step 2: Prep all toppings

Clean the mushrooms with a damp towel and slice them about 3 mm thick. Finely chop the shallot and mince the garlic. Grate the cheeses and toss them together. Thinly slice the pickles and chop the chives. Split the baguette lengthwise and, if you like, pull out a little of the inner crumb to make a shallow trough so the topping stays put.

Step 3: Sauté the mushrooms until deeply browned

Heat a large skillet over medium-high. Add the butter and olive oil. When foaming subsides, add the mushrooms and 1/2 tsp of the salt. Cook, stirring occasionally, until they release moisture and then begin to brown, 7–9 minutes. Add the shallot and cook 1 minute. Stir in the garlic, marjoram, remaining 1/2 tsp salt, and pepper; cook 30–60 seconds until fragrant. Off the heat, stir in Maggi/soy (if using). The mixture should be savory and fairly dry—this keeps the bread crisp.

Step 4: Pre-toast the baguette

Place the split baguette, cut-side up, on the sheet pan. Lightly brush or drizzle the cut sides with 1 tsp olive oil. Bake 3–4 minutes until the edges feel crisp. This quick pre-toast prevents sogginess under the mushrooms.

Step 5: Load with mushrooms and cheese

If using, spread a thin layer of mustard on the warm bread. Divide the mushroom mixture evenly over both halves, right to the edges. Top with the grated cheeses, pressing lightly so the cheese adheres.

Step 6: Melt, then bubble the cheese

Bake at 475°F (245°C) for 5–7 minutes until the cheese is melted. Switch to broil and cook 1–2 minutes, watching closely, until the top is spotty-golden and bubbling.

Step 7: Finish like street-style and serve

Let the zapiekanka rest 2 minutes so the cheese sets slightly. Drizzle with ketchup in a zig-zag, shower with chives, and lay the sliced pickles over or alongside. Cut into 4 portions and serve hot and crisp.

Pro Tips

• Dry mushrooms = crisp bread. Cook off their moisture until the pan looks nearly dry before topping the bread.
• Marjoram is classic in Poland. If you do not have it, thyme works, but the flavor will be slightly different.
• Pre-toasting is key. It keeps the crumb from soaking up juices, so the base stays crunchy under all that cheese.
• Use mostly Gouda/Edam for flavor and a little mozzarella for stretch. Coarser grating gives better browned bubbles.
• Broil with the door ajar if your oven allows, and keep your eye on it—bubbling turns to burnt quickly.

Variations

• Kraków Classic: Skip mozzarella; use only Gouda or Edam. Finish with ketchup and chives, pickles on the side.
• Kielbasa Zapiekanka: Add thin slices of smoked kielbasa or ham over the mushrooms before the cheese.
• Wild Mushroom & Truffle: Use chanterelles/porcini mix; finish the sauté with a few drops of truffle oil before topping.

Storage & Make-Ahead

Cook the mushroom topping up to 3 days ahead; refrigerate in an airtight container and rewarm in a skillet to drive off moisture before assembling. You can assemble the baguette up to 1 hour before baking. Leftover zapiekanka keeps 1 day refrigerated; reheat on a sheet pan at 375°F (190°C) for 8–10 minutes, then broil briefly to re-crisp. Freezing assembled zapiekanka is not recommended, but the sautéed mushrooms can be frozen up to 1 month.
