Polish Garlic Bread: Buttery, Crisp Zapiekanka

Polish garlic bread, often made in the style of zapiekanka, is an open-faced baguette topped with sautéed mushrooms, cheese and garlic butter, then baked until crisp and bubbling. This popular Polish street-food snack is easy to adapt: keep the mushrooms and cheese for a classic feel, or add toppings to suit what you have.

Ingredients

1 small baguette, about 12 oz (340 g), preferably a day old
2 tablespoons (30 ml) olive oil
8 oz (225 g) white or cremini mushrooms, finely chopped
2 tablespoons (28 g) unsalted butter, softened
2 medium garlic cloves, finely grated or minced
¼ teaspoon fine salt, plus more to taste
⅛ teaspoon freshly ground black pepper
1½ cups (150 g) grated low-moisture mozzarella
½ cup (50 g) grated Gouda or mild cheddar
2 tablespoons (8 g) finely chopped fresh parsley
4 tablespoons (60 ml) ketchup, for serving, optional

Instructions

Heat the oven to 425°F (220°C). Line a rimmed baking sheet with parchment paper. Cut the baguette lengthwise into two halves, then cut each half crosswise into two pieces, making four portions. If the bread is very fresh and soft, set the cut pieces aside while you prepare the mushrooms so their cut surfaces can dry slightly.
Warm the olive oil in a large skillet over medium-high heat. Add the chopped mushrooms in an even layer and cook for 7–9 minutes, stirring occasionally, until they release their moisture and the pan is nearly dry. Season with the salt and pepper. Take the pan off the heat and let the mushrooms cool for a few minutes; wet or steaming-hot mushrooms can make the bread soggy.
Stir together the softened butter and garlic in a small bowl. Spread a thin, even layer over each cut surface of bread, reaching close to the edges. Use the full amount for a distinct garlic flavor, or hold some back for a milder result.
Divide the cooked mushrooms between the bread pieces. Sprinkle over the mozzarella and Gouda, covering the mushrooms in an even layer. Arrange the pieces on the baking sheet with a little space between them.
Bake for 8–10 minutes, until the cheese is melted and bubbling and the bread edges are crisp. For more browned cheese, switch the oven to broil for 1–2 minutes at the end, watching continuously; broilers can scorch bread quickly. Remove the tray as soon as the tops are golden.
Scatter with parsley and serve hot, with ketchup on the side if desired. Let each piece sit for a minute before serving so the molten cheese is less likely to slide off.

Tips

Cook the mushrooms until dry. Mushrooms contain plenty of water. Keep cooking until their liquid evaporates; otherwise it can soak into the bread while baking.
Choose bread with structure. A baguette or other narrow, crusty loaf supports the toppings. Very soft sandwich bread tends to bend and turn soggy. If you only have a soft loaf, toast the cut sides for 3–4 minutes before adding the toppings.
Adjust the garlic carefully. Two cloves give a noticeable but balanced flavor. For a gentler taste, use one clove; for more punch, add a small amount of grated garlic after baking rather than adding a lot to the butter, which can burn at the edges.
Keep toppings modest. A thick pile makes the bread hard to pick up and prevents the cheese from melting evenly. If adding extra toppings, cook watery vegetables first and drain them well.

Serving Suggestions

Serve zapiekanka as a snack, casual lunch or light supper while it is hot and crisp. A simple cucumber salad, sliced tomatoes or a green salad with a sharp vinaigrette balances the buttery cheese. For a more substantial meal, pair a piece with vegetable soup or a bowl of broth. Ketchup is a familiar Polish-style finishing touch, but it is optional; mustard or a little hot sauce also works.

Variations

Use a different cheese: Polish oscypek, a smoked sheep’s-milk cheese, can be difficult to find and has a distinctive salty, smoky flavor. Substitute smoked Gouda for a similar smoky note, or use mozzarella alone for a milder, stretchy topping. Keep the total cheese quantity close to the recipe amount so it melts without weighing down the bread.

Add onion: Cook ¼ cup (40 g) finely chopped onion with the mushrooms, allowing a few extra minutes for it to soften. The result is sweeter and more savory.

Try other toppings: Add a few slices of cooked ham, roasted red pepper or thinly sliced pickles under the cheese. These are optional modern variations rather than requirements for this mushroom-topped version. Drain or pat wet ingredients dry before using.

Make it without mushrooms: Replace them with 1 cup (150 g) finely chopped, cooked vegetables such as zucchini or bell pepper. Cook off excess moisture first; the flavor and texture will differ from the classic mushroom topping.

Storage and Reheating

For best texture, eat the bread shortly after baking. Refrigerate leftovers within 2 hours in a covered container and use within 3–4 days. The topping may soften the bread in storage, but reheating in an oven or toaster oven helps crisp it again. Heat at 375°F (190°C) for about 6–10 minutes, until hot throughout and the cheese is bubbling. For food safety, leftovers should reach 165°F (74°C) when checked with a food thermometer. Avoid leaving the bread at room temperature for longer than 2 hours, or 1 hour if the temperature is above 90°F (32°C).

You can freeze the assembled, unbaked pieces on a tray until firm, then wrap and freeze for up to 2 months for best quality. Bake from frozen at 400°F (200°C), adding several minutes and checking that the center is hot and the cheese melted. Alternatively, freeze baked portions; thaw overnight in the refrigerator before reheating. The bread may be softer after freezing.

Frequently Asked Questions

Is Polish garlic bread the same as zapiekanka?
Zapiekanka is a Polish open-faced baguette sandwich, commonly topped with mushrooms and cheese and baked until hot. Garlic butter is a tasty addition, though recipes and toppings vary by cook and region; it is not the only way to make zapiekanka.

Can I make it without a baguette?
Yes. Use a sturdy ciabatta, crusty roll or another firm bread, cut to a similar thickness. Adjust the baking time slightly for smaller or thinner pieces and remove them when the cheese bubbles and the edges are crisp.

Can I prepare it ahead?
You can cook the mushrooms and mix the garlic butter up to a day ahead, storing them separately in covered containers in the refrigerator. Assemble the bread just before baking for the crispest result. If the butter firms up, let it soften briefly at room temperature before spreading.

Why did my bread turn soggy?
The most common cause is moisture from mushrooms or other toppings. Cook mushrooms until the skillet is nearly dry, cool them briefly, and avoid piling on wet ingredients. A sturdy loaf and a brief pre-toast of soft bread also help.

Do I need to use ketchup?
No. Ketchup is a popular accompaniment, but the bread is delicious without it. Serve it on the side so everyone can choose, or try mustard, hot sauce or no sauce at all.

Can I make this in an air fryer?
Yes, if the bread pieces fit without crowding. Air-fry at about 350°F (175°C) for 5–8 minutes, checking early because models vary and the bread can brown quickly. Cook in batches if needed, and stop when the cheese is melted and the edges are crisp.
