Instructions

Step 1: Cook the Sweet Potatoes

Place 1½ pounds peeled and diced sweet potatoes in a medium pot and cover with water.
Bring to a boil, reduce to a simmer, and cook for 12–15 minutes until very tender. Drain and let cool slightly.

Tip: Dice sweet potatoes into small pieces for faster cooking; ensure they’re soft for easy pureeing.

Step 2: Form the Patty Mixture

In a food processor, combine the cooked sweet potatoes, 4 cups cauliflower rice, ⅓ cup sesame seeds, 2 garlic cloves, 1 tsp paprika, 1 tsp cumin, ½ tsp coriander, 1¼ tsp kosher salt, and ¾ tsp black pepper. Puree until smooth.
Add 1 large egg and pulse to combine.
Add ¼ cup all-purpose flour and 1 cup bread crumbs; pulse just until evenly incorporated.

Tip: Don’t over-process after adding flour and crumbs to avoid a gummy texture.

Step 3: Shape the Patties

Divide the mixture into 4 even portions and form into round patties, about ½-inch thick.

Tip: Wet your hands slightly to prevent sticking; chill patties for 10 minutes in the fridge if they’re too soft to handle.

Step 4: Cook the Patties

Heat 2 Tbsp extra-virgin olive oil in a large skillet over medium heat.
Add the patties and cook for about 4 minutes per side, flipping once, until golden brown and firm.

Tip: Cook in batches if needed to avoid overcrowding; use a spatula to flip gently to maintain shape.

Step 5: Prepare Toppings

In a small bowl, whisk together 4 Tbsp mayonnaise and 2 tsp hot sauce.
In another small bowl, mash 2 avocados with 2 Tbsp lemon juice until smooth.

Tip: Adjust hot sauce to taste for desired spice level; mash avocado to your preferred consistency.

Step 6: Assemble the Burgers

Spread the spicy mayonnaise on the bottom half of each of 4 kaiser rolls (or keto buns).
Top each with a lettuce leaf, a cauliflower sweet potato patty, a dollop of avocado mixture, and ½ cup sliced green onions (divided evenly).
Place the top half of the bun on each burger and serve immediately.

Tip: Toast buns lightly for extra texture; assemble just before serving to keep buns crisp.
