Whether you’re serving these for a family dinner, a casual get-together, or just because, they’re a guaranteed hit. Plus, kids will love the mini size, and they’re packed with sneaky veggies, so it’s a win-win!

What You’ll Need

Ingredients:

  • 2 medium avocados (ripe, sliced)
  • 6 small slider buns (toasted)
  • 2 cups mixed veggies (shredded carrots, zucchini, and spinach)
  • 1/2 cup breadcrumbs
  • 1/4 cup grated parmesan (optional, or use vegan alternative)
  • 1 egg (or flax egg for vegan option)
  • 1 tsp garlic powder
  • 1/2 tsp smoked paprika
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 2 tbsp olive oil (for cooking patties)
  • 6 small lettuce leaves
  • 6 slices of tomato
  • Optional: 2 tbsp mayo or chipotle sauce

Pro Tips

  1. Use ripe avocados: They should be soft but not mushy—perfectly creamy for layering on your sliders.
  2. Veggie texture matters: Shred your veggies finely so the patties hold together well and are easy for kids to eat.
  3. Toast the buns: A lightly toasted bun adds that extra crunch and keeps them from getting soggy.
  4. Adjust spices: If kids don’t love smoky flavors, use less paprika or sub in mild herbs like parsley.
  5. Keep extras warm: Store cooked patties in a warm oven if you’re assembling sliders for a crowd.

Tools You’ll Need

  • Medium mixing bowl
  • Grater or food processor
  • Non-stick skillet
  • Spatula
  • Knife and cutting board

Substitutions and Variations

  • Gluten-free: Swap breadcrumbs for gluten-free breadcrumbs.
  • Vegan: Use a flax egg (1 tbsp flaxseed meal + 3 tbsp water) and vegan parmesan.
  • Cheesy slider: Add a slice of melted cheddar or gouda.
  • Spice it up: Add chili flakes or a dash of hot sauce to the patties or sauce.

Make-Ahead Tips

  • Prepare the veggie patties in advance and store them in the fridge (uncooked) for up to 2 days or freeze them for up to 1 month. Cook them fresh when ready to assemble the sliders.

Instructions

1. Prep the Veggies

Grate the carrots and zucchini, and finely chop the spinach. Squeeze out any excess water from the zucchini using a clean kitchen towel.

2. Mix the Patty Mixture

In a medium mixing bowl, combine the shredded veggies, breadcrumbs, grated parmesan, egg, garlic powder, smoked paprika, salt, and pepper. Mix until it forms a cohesive mixture.

3. Form the Patties

4. Cook the Patties

Heat 2 tablespoons of olive oil in a non-stick skillet over medium heat. Cook the patties for 3-4 minutes on each side until golden and firm.
