    This spicy cauliflower burger recipe is the best saucy, finger-licking good, plant-based sandwich you’ll ever want. I haven't met a person yet who doesn't love this spicy veggie burger - vegan or not!

    Made with cauliflower cutlets baked until tender-sweet with a thick caramelized spicy harissa sauce, this burger is succulent and saucy. Creamy vegan tzatziki wakes everything up, tangy slaw adds texture, and sweet crunchy pickles push it over the top.

    This epic beauty is a cross between the popular Buffalo Cauliflower sandwich and the decadent Chicken-fried Cauliflower sandwich - spicy without the Buffalo sauce and crunchy without the frying!

    Pro Tip: break the extra cauliflower pieces into florets and this spicy cauliflower recipe becomes the perfect cauliflower appetizer or game day food served as hot wings with your favorite dipping sauce like ranch or tzatziki.

    Okay, let’s get started.

    Spicy Cauliflower Burger Ingredients

    This cauliflower burger is easy to make and is pretty versatile. Sub in any vegetables and sauces you enjoy on top of your burger. Here's what I used:

    Cauliflower slices dredged in spicy batter on a baking sheet.
    Harissa covered cauliflower slices on a baking sheet.

    Cauliflower – baked until tender and sweet. The baked cauliflower paired with spicy harrisa is a flavor match made in heaven. Traditionally cut into steaks, I prefer a slightly smaller cutlet for this cauliflower burger. (more below).

    Cauliflower batter – putting spices in the batter adds another layer of flavor that gets into the crevices and pockets of the cauliflower steaks. Mix to the consistency about the same as or slightly thinner than pancake batter. Can use gluten-free flour!

    A bowlful of spicy harissa sauce for cauliflower burgers.

    Harissa sauce – harissa is a spicy condiment popular in Tunisian cooking. Whisk vegan mayonnaise with harissa spice for a deliciously outrageous and finger-licking good thick and spicy sauce.

    Bun – because this cauliflower filling isn’t fried and ultra crispy, I like to use a crustier roll for some added crunch. A toasted ciabatta, sourdough or pretzel bun is a good choice. However, if you love a soft potato or brioche bun, just toast it before serving!

    Slaw – zingy slaw to cool things off and cut through the richness and spiciness of the harissa sauce.

    Tzatziki sauce - easy to make, creamy, and super tangy, this bright and fresh tzatziki sauce is the perfect compliment to the spicy cauliflower. Can sub with Vegenaise, Ranch or Blue Cheese Sauce (we like Follow Your Heart brand).

    Optional toppings - thick tomato slice for freshness, Gherkin pickles for sweetness and crunch, white/red onion slices for pungency and leafy greens for freshness.

    Ingredient Spotlight – Cauliflower

    I always say, if you’ve got a cauliflower; you’ve got a meal! It is so delicious, inexpensive, highly available, and beyond versatile.

    Also cauliflower is a healthy, low calorie and carbohydrate vegetable choice with an excellent nutrient profile. It’s wonderful raw, cooked, baked, steamed, grilled or even fried.

    Cauliflower has always been one of my favorite vegetables. I use it to make simple, comfort food like Rosé Veggie Pasta Sauce, this hearty and healthy Bolognese recipe, and my Curry Cauliflower Rice Soup. If you like tacos, try this super popular and simple Chickpea Cauliflower Taco recipe or these easy Tacos with Cauliflower-walnut Crumbles.

    The humble cauliflower can also be used to make pancakes, cheese sauce, desserts, falafels, and dips. There’s really nothing cauliflower can’t do!

    How to Slice Cauliflower into Steaks and Cutlets

    Prepare the cauliflower by removing leaves and trimming any excess stem. With a large, sharp knife, slice the cauliflower into ½” ‘steaks’. The outer edges of the head of cauliflower will not remain in one piece; however, they will create pretty good size cutlets.

    Since they are attached to the main stem of the cauliflower, the center two slices “steaks” should remain completely intact.

    I cut these large steaks in half and trim off some of the main stem so they cook more evenly and fit nicely on the bun.

    How to Make a Cauliflower Sandwich

    Although there are a few components to prepare for this burger recipe, everything is easy. Here’s the step-by-step guide for best practices and kitchen management . . .

    • Cut and trim the cauliflower.
    • Make the spicy batter.
    • Coat the cauliflower pieces and place on a parchment-lined baking sheet. Bake until tender and sweet on the inside and slightly crunchy and golden on the outside.
    • While the cauliflower is baking, prepare the spicy harissa sauce, the tangy slaw, as well as any optional toppings (onions, tomatoes, pickles, greens).
    • Remove the cauliflower from the oven and slather with the spicy harissa sauce then back into the oven for 5-7 minutes until the top is bubbly and caramelized.
    • Butter and toast the buns until crispy and golden then pile everything on top.
    • Don’t forget extra napkins.

    Storage Tips & Leftovers

    The cauliflower is best served straight out of the oven. However, if you have some leftover (lucky), store them in the fridge and use them over the next two days in a Buddha bowl, as a pizza topping or vegan taco filling. I love getting two meals from one!

    INGREDIENTS

    Preparing and Cutting the Cauliflower

    • 1 cauliflower, cut into cutlets

    Spicy Cauliflower Batter

    • ½ cup AP flour (sub gf flour)
    • 1 teaspoon onion powder
    • 1 teaspoon garlic powder
    • 1 teaspooon smoky paprika (or paprika)
    • S&P to taste
    • ¾ cup water

    Harissa Sauce

    • 3-4 tablespoons Vegenaise (vegan mayo)
    • 1 ½ tablespoons harissa spice blend

    Simple Slaw

    • 3 cups shredded cabbage or slaw mix
    • cilantro, chopped
    • 2 tablespoons Vegenaise
    • 1 tablespoon vinegar
    • 1 teaspoon maple syrup
    • salt and pepper to taste

    Make vegan Tzatziki Sauce or sub vegan mayo or store-bought ranch or blue cheese dressing

      Optional Toppings

      • 2-4 tomato slices, thick
      • 2-4 red onion slices, thick
      • leafy greens (lettuce, spinach, arugula)
      • 4 gherkin pickles
      • 4 buns (ciabatta, cheese, pretzel)

      INSTRUCTIONS
       

      • Preheat oven to 425º F.  Prepare a baking sheet with parchment.

      Preparing and Cutting the Cauliflower

      • Cut the cauliflower head into ½" slices or medium size florets.
      • You will get some smaller cutlets/nuggets as well (perfect for sliders).

      Cauliflower Batter

      • Add all ingredients to a medium bowl and whisk together. Stir in ½ cup of the water until incorporated - add the remaining water if needed to achieve a pancake batter consistency.
      • Dip the cauliflower pieces into the batter. Use a pastry brush or your hands to make sure the batter gets in all the crevices and pockets of the cauliflower.
      • Place on parchment-lined baking sheet and then into the oven for ~20-25 minutes.
      • If your cauliflower pieces are larger/thicker, you'll need to adjust the cooking time. Test with a fork for tenderness - should be tender but still firm. Up to 40 minutes if the pieces are larger.

      Creamy Harissa Sauce

      • Meanwhile, whisk the harissa sauce in a small bowl - it will be thick.
      • When the cauliflower has cooked for ~25 minutes, remove it from the oven and using a brush, slather the harissa sauce very generously on the tops and edges of the cauliflower pieces.
      • Bake for another 5-8 minutes until the cauliflower is soft and tender and the harissa sauce is bubbly and caramelizing. *The smaller pieces/nuggets will be ready much faster.

      Meanwhile make the Tzatziki Sauce Recipe or sub with vegan mayo, vegan ranch dressing or blue cheese sauce.

      • Make the tzatziki sauce for slathering on the buns.

      Quick and Easy Slaw

      • In a medium bowl, whisk the dressing ingredients together.
      • Add the cabbage and cilantro and toss until well coated.

      To Serve

      • Cut the buns in half and toast them in the oven or on the grill. Buttered or plain.
      • Smother the toasted bun with tzatziki sauce (mayo or your favorite dairy-free ranch or blue cheese sauce). Top with a few cauliflower cutlets, a heap of slaw, and any optional toppings.

      NOTES

      Cauliflower - I typically don't go for big steaks as I find them too clunky for the buns. I prefer the cutlet size (see photos).
      Smaller cutlets are perfect for this recipe and any extra florets are fantastic to make cauliflower wings for game day or date night!
      Harissa Sauce - meant to be applied liberally so it bubbles up and is slightly caramelized on top of the cauliflower for the most delicious finger-licking good saucy crust!!!!
      Leftovers - leftover cutlets are amazing next day in Buddha bowls, vegan tacos, and on top of pizza!

          Crispy outside and almost flaky on the inside -- amazing texture for a sandwich.
