Recipe Tips
- Use 80/20 ground beef for juicy patties.
- Do not overcrowd the pan while cooking patties to ensure even browning.
- For faster onion caramelization, slice onions thin and cook on slightly higher heat while stirring frequently.
- Cheese slices can be doubled for extra gooeyness.
- Press buns lightly while toasting to avoid burning.
Variations
- Mini Turkey or Chicken Sliders: Substitute ground turkey or chicken for beef.
- Spicy Sliders: Add jalapeños or sriracha mayonnaise for a kick.
- Vegan Version: Use plant-based patties, vegan cheese, and caramelized onions.
- Gourmet Toppings: Add sautéed mushrooms, arugula, or aioli for a restaurant-style slider.

Freezing and Storage

- Freezing: Patties can be frozen before assembling for up to 1 month. Thaw in the refrigerator before cooking.
- Assembled Sliders: Best served fresh; assembled sliders do not freeze well due to buns and toppings.
