• Brush Butter Generously: Use a pastry brush to coat slider tops uniformly, ensuring golden-brown, glossy, and flavorful bread surfaces.

Storing Vegetarian Cheesy Mushroom Sliders Like a Pro

• Refrigeration: Store leftover sliders in an airtight container for up to 3 days. Wrap each slider individually in aluminum foil to prevent moisture loss and preserve flavor.
• Reheating: Warm sliders in a preheated oven at 350°F for 8-10 minutes. Covering with foil helps maintain moisture and prevents bread from becoming too crispy. Check internal temperature reaches 165°F for food safety.
