FAQs

Can I use any type of bread?

Soft sandwich bread works best. Avoid very thick or crusty bread for easier sealing and baking.

Do I have to remove the crusts?

Yes, removing crusts helps the bread seal more easily and gives a neater appearance.

What mushrooms work best?

Button, cremini, or portobello mushrooms are ideal for their flavor and texture.

Can I make these ahead of time?

Yes, prepare and refrigerate unbaked squares for up to 8 hours before baking.

Can I make these gluten-free?

Yes, use gluten-free sandwich bread and check all ingredients for gluten-free certification.

Is it okay to skip cream cheese?

Yes, though it helps bind the filling. You can substitute with ricotta or mashed potato for texture.

Can I air-fry them?

Yes, air fry at 190 °C (375 °F) for 8–10 minutes or until golden and crisp.

What dipping sauces pair well?

Garlic aioli, sour cream, marinara, or ranch dressing complement these well.

How do I keep the bread from splitting open?

Don’t overfill, and press edges firmly. Lightly wet the edges to help them seal.

Can I serve these at room temperature?

Yes, they hold up well and can be served warm or room temp for gatherings.
