    Eggplant is one of my favorite ingredients to cook with. It's the perfect canvas for flavor, absorbing whatever delicious seasonings you throw its way. Take my gochujang eggplant, for instance - the way the eggplant soaks up the spicy, fermented Korean paste is nothing short of miraculous.

    But today, we're taking this versatile veggie in a new direction: vegan burgers. Trust me, once you've tried these eggplant patties topped with caramelized onions, you'll understand what's so special about this humble ingredient.

    👨‍🍳How To Make An Eggplant Burger

    Eggplant on a baking tray.

    Step 1

    • Preheat oven to 425°F (220°C).
    • Brush eggplant slices with olive oil and season with smoked paprika, garlic powder, cumin, salt, and pepper. Roast for 20-25 minutes, flipping halfway through, until tender and golden.

    Step 2

    While eggplant is roasting, make caramelized onions: Heat olive oil in a pan over medium-low heat. Add sliced onions and cook slowly, stirring occasionally, for about 25-30 minutes until golden brown. Add balsamic vinegar and brown sugar, cook for another 5 minutes. Set aside.

    Step 6

    Form mixture into 4 patties. Heat a skillet over medium heat with a bit of oil. Cook patties for 3-4 minutes on each side until golden and crispy.

    • Assemble burgers: Place eggplant patty on bottom bun, top with caramelized onions, tomato slice, and arugula. Close with top bun.

    What To Serve With Eggplant Burgers

    • Garlic Truffle Fries: These garlic truffle fries would be the perfect side to this vegan burger.
    • Vegan Macaroni Salad: You can't go wrong with a macaroni salad!
    • Jerusalem Salad: This simple cucumber and tomato salad would be the perfect accompaniment to eggplant burgers.
    • Coleslaw: This kale and apple slaw is a healthy, vegan twist on classic coleslaw

    ❄️Storage Instructions

    Refrigerator

    Allow the cooked eggplant patties to cool completely. Place them in an airtight container, separating layers with parchment paper. Store in the refrigerator for up to 3-4 days.

    To reheat, warm in a skillet over medium heat for 2-3 minutes per side, or in the oven at 350°F (175°C) for about 10 minutes.

    I recommend storing the caramelized onions and aioli separately and assembling your eggplant burger just before eating.

    Freezing Uncooked Patties

    Form the eggplant mixture into patties. lace the patties on a baking sheet lined with parchment paper and freeze until solid (about 2 hours). Transfer the frozen patties to a freezer-safe bag or container, separating layers with parchment paper. They should stay fresh in the freezer for up to 3 months.

    To cook the patties from frozen, thaw them in the refrigerator overnight, then cook as per the instructions above.
