Step-by-Step Instructions
Making these Cauliflower Sweet Potato Burgers is straightforward and flavorful, with a simple prep and cooking process. Follow these steps for perfect patties every time.
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.
Assembly: Building the Perfect Cauliflower Sweet Potato Burger
Making these Cauliflower Sweet Potato Burgers is all about creating a hearty, flavorful patty with vibrant toppings. Here’s how to make them perfect:
- Cook Sweet Potatoes Tender: Ensure they’re very soft for a smooth puree.
- Form Firm Patties: Blend just enough to combine ingredients; chill if needed for easier shaping.
- Cook for Crispness: Fry until golden to achieve a crispy exterior.
- Layer Thoughtfully: Balance creamy mayo, avocado, and crisp lettuce for a burger-like experience.
Presentation Tips:
- Serve on a platter with extra green onions or a sprinkle of sesame seeds for a vibrant look.
- Pair with a keto-friendly side like a cucumber salad, coleslaw (no sugar), or grilled zucchini.
- Garnish with extra hot sauce, fresh herbs, or a lemon wedge for a polished finish.
Storage and Make-Ahead Tips
These burgers are great for meal prep but require careful storage to maintain texture. Here’s how to keep them fresh:
- Storing Leftovers:
- Store cooked patties in an airtight container in the refrigerator for up to 4 days.
- Store toppings (mayo, avocado, lettuce, green onions) separately to maintain freshness.
- Freeze uncooked or cooked patties for up to 3 months, layered with parchment paper in a freezer-safe container.
- Reheating:
- Reheat patties in a skillet over medium heat for 2–3 minutes per side or in an oven at 350°F for 8–10 minutes.
- Microwave for 1–2 minutes, but this may soften the texture.
- Make-Ahead Tips:
- Prep patty mixture and form patties up to 1 day ahead; refrigerate until ready to cook.
- Cook patties and store up to 3 days ahead; reheat before assembling.
- Prepare mayo and avocado toppings up to 1 day ahead; store separately in the fridge.
Tip: Assemble burgers just before serving to prevent buns from getting soggy.
Recipe Variations
These Cauliflower Sweet Potato Burgers are versatile, drawing on your love for vibrant, veggie-packed dishes like Grilled Flatbread Pizza and Greek Chicken and Rice Skillet. Here are some fun ideas:
- Keto Cauliflower Burgers: Replace flour and bread crumbs with almond flour and crushed pork rinds; use keto buns or lettuce wraps; reduce sweet potatoes to ½ pound and increase cauliflower rice to 5 cups for lower carbs.
- Spicy Veggie Burgers: Add ½ tsp cayenne or chili powder to the patty mix or increase hot sauce in the mayo.
- Gluten-Free Version: Use gluten-free flour (e.g., almond or coconut) and gluten-free bread crumbs or almond meal; ensure buns are gluten-free.
- Vegan Version: Replace egg with a flax egg and use vegan mayo; ensure buns are vegan-friendly.
- Mediterranean Burgers: Add ¼ cup crumbled feta and 2 Tbsp chopped olives to the patty mix; top with tzatziki instead of mayo.
