Sweet potatoes are the star here. Orange-fleshed ones like Garnet or Jewel work best—they're sweeter and creamier when roasted. Grab a couple of medium-sized ones from the produce section, or Costco if you're making a big batch. Roast them whole until tender (about 45 minutes at 400°F), then mash them while warm. The lentils? Red lentils cook faster than green and hold their shape better—Trader Joe's sells them pre-packaged, or check the bulk bins at Whole Foods. No need to soak them; just rinse and cook with broth for 15 minutes.
No flaxseed meal? Chia seeds mixed with water works too—same ratio, just stir it in. Short on smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. The onion and garlic can be swapped for green onions or shallots if you're feeling fancy. For extra crispiness, try panko breadcrumbs mixed into the patties before frying. And if you're in a rush, pre-cooked lentils from a can (drained and rinsed) save time—just add an extra tablespoon of flour or cornstarch to help bind everything.
Roasted sweet potatoes keep in the fridge for 5 days if wrapped tightly, but they're best used fresh. Cooked lentils? Store them in an airtight container for 4-5 days or freeze for 3 months. Once you've formed the patties, they're easiest to freeze raw—just lay them on a tray to flash-freeze, then transfer to a bag. Cook from frozen (add 2-3 minutes), and they'll still be crispy on the outside and tender inside. These patties reheat beautifully—toaster oven or air fryer is your friend for extra crispiness.

Step-by-step instructions for sweet potato patties with red lentils
Here's how to make hearty, flavorful patties that stay together and deliver perfect texture every time.
🔥 Step 1: Roast the Sweet Potatoes Until Tender
Preheat your oven to 400°F and line a baking sheet with parchment paper. Pierce the 2 large medium sweet potatoes with a fork in several places, then rub them with 1 tablespoon of the olive oil to prevent sticking. Roast for 45-50 minutes until a knife slides in easily and the flesh is fork-tender.
Here's the thing—don't overcook them or they'll turn to mush when you mash. You want them soft enough to mash completely but still holding just enough structure to bind the patties later. Let them cool for 10 minutes before handling, then scoop out the flesh and discard the skins.
🍳 Step 2: Cook the Red Lentils Until Creamy
While the sweet potatoes roast, heat 0.5 cup vegetable broth in a small saucepan over medium-high heat. Add the 1 cup red lentils and bring to a boil, then reduce heat to low and simmer uncovered for 15-18 minutes until the lentils are tender and the liquid has mostly absorbed.
You'll know they're done when they're soft but still hold their shape slightly—like al dente pasta. Drain any remaining liquid through a fine-mesh strainer and set aside to cool. The lentils should yield about 1½ cups of cooked lentils. This is your secret ingredient for binding those patties without adding extra fat.
👨🍳 Step 3: Sauté Aromatics and Spice Blend
Heat 0.5 cup avocado oil in a large skillet over medium heat. Add the 1 medium yellow onion and cook for 5-6 minutes until softened and translucent. Add the 3 cloves minced garlic and cook for 30 seconds until fragrant—don't let it brown or it'll turn bitter.
In a small bowl, mix together 1 tsp ground cumin, 1 tsp smoked paprika, 1 tsp ground coriander, 0.75 tsp salt, and 0.5 tsp black pepper. Sprinkle this spice blend over the onions and garlic, stirring for 30 seconds to toast the spices and release their aromas. Let this mixture cool completely before mixing with other ingredients.
🥘 Step 4: Combine and Bind the Patty Mixture
In a large bowl, mash the roasted sweet potatoes until completely smooth—no lumps. Stir in the cooked lentils, onion-garlic-spice mixture, and 2 tbsp flaxseed meal mixed with 6 tbsp water (this creates an egg-like binder). The mixture should be thick but still moldable—if it's too dry, add 1 tablespoon water at a time until it reaches the right consistency.
Here's where it gets fun—fold in the 0.25 cup chopped fresh cilantro and mix gently. The flax mixture should bind everything together when pressed. If the mixture feels too loose, chill it in the refrigerator for 15 minutes to firm up. This step is crucial for patties that hold their shape when frying.
🔥 Step 5: Pan-Fry Until Golden and Crispy
Heat 1 tablespoon avocado oil in a skillet over medium heat. Scoop the mixture into 4 equal portions and shape into ½-inch thick patties. Press down gently with your palm to ensure they hold together. Fry for 4-5 minutes per side until golden brown and crispy on the outside.
Don't rush this step—they should develop a nice crust that's golden brown all over. You'll know they're ready when the edges are crispy and the center is heated through. Transfer to a paper towel-lined plate to drain any excess oil. Serve immediately with your favorite dipping sauce or alongside a fresh salad for a complete meal.
Pro Tips For Making Sweet Potato Patties With Red Lentils
- Roast the Sweet Potatoes: Toss cubed sweet potatoes in olive oil, salt, and a pinch of cumin before roasting at 425°F (220°C) for 20-25 minutes—until they’re tender enough to mash easily. I used to boil them, but roasting adds depth and caramelized edges that hold the patties together better.
- Cook Lentils Until They’re Dry: Drain the red lentils when they’re fully tender but still slightly firm—no soupy residue. Overcooked lentils turn mushy and make the patties fall apart. Rinse them after cooking to remove excess starch if needed.
- Soak the Onion First: Dice the onion and let it sit in cold water for 10 minutes before cooking to mellow its sharpness. Drain and pat dry—this softens the bite and prevents the patties from tasting raw or harsh.
- Press the Patties Firm: Don’t just shape the mixture—press it into thick patties (about ¾-inch) and flatten the edges to prevent crumbling. A quick trick: Use your palm to press down hard, then chill them for 10 minutes before cooking. They’ll hold together like a pro’s.
Regional styles of this dish
Southern Comfort Style
In the South, these patties get a smoky, soulful twist with added ingredients like collard greens or smoked Gouda (for non-vegans). I like to stir in ½ cup finely chopped collards with the lentils and cook them down with the onions for extra depth.
A dash of hot sauce or Cajun seasoning (about ½ tsp) on top of the patties before serving adds the perfect kick. Serve with cornbread and a tomato-based salsa for a true Southern-inspired meal. 🌶️
Indian-Inspired Masala Patties
For a flavor-packed Indian variation, swap the spices for 1 tsp garam masala, ½ tsp turmeric, and ½ tsp cayenne pepper. Add ½ cup finely diced bell peppers and ½ cup chopped cilantro to the mixture.
Cook the lentils in ½ cup coconut milk instead of broth for extra richness. Serve with mint chutney or raita for a refreshing contrast. These patties are perfect with naan bread or alongside a cucumber salad. 🌿
Mexican Street Tacos
Transform these patties into taco-style bites by adding ½ cup black beans (mashed) to the mixture and seasoning with 1 tsp chili powder and ½ tsp oregano. Shape them into small, 1-inch patties and pan-fry until crispy.
Serve on corn tortillas with avocado slices, pico de gallo, and a drizzle of lime crema (mix ½ cup vegan sour cream with 1 tbsp lime juice). These are perfect for taco nights or as a fun appetizer. 🌮
Middle Eastern Mezze Twist
For a Middle Eastern-inspired version, add ½ cup finely chopped parsley and ½ cup toasted pine nuts to the mixture. Season with 1 tsp ground cumin, ½ tsp cinnamon, and a pinch of cardamom.

Frequently asked questions
Why do I need to roast the sweet potatoes instead of boiling them?
Roasting caramelizes the natural sugars in sweet potatoes, creating deeper flavor and a slightly crispy texture that holds up better when formed into patties. Boiled sweet potatoes turn out watery and lose their structure, making the patties difficult to shape and prone to falling apart. Roasting also gives that perfect golden crust when pan-frying.
Can I make these patties without flaxseed?
Yes! Use 2 tablespoons chia seeds mixed with 6 tablespoons water (let it sit for 5 minutes to thicken) as a 1:1 substitute. For extra binding power, add 1 tablespoon cornstarch to the mixture. The flax/chia acts as an egg substitute to hold the patties together while frying.
How do I prevent the patties from crumbling when cooking?
Chill the mixture for 15 minutes before shaping to firm it up, and press each patty firmly when forming. Use medium heat (not high) when pan-frying to develop a crust gradually. If they still crumble, add 1 tablespoon breadcrumbs to the mixture for extra structure. The flax binder needs time to activate fully.
Are these patties good cold or reheated?
They reheat beautifully! Warm in a 350°F oven for 10 minutes or air fryer for 5 minutes to restore crispiness. Cold patties work well in salads or wraps, but they're best enjoyed fresh when the texture is at its peak. For leftovers, store in an airtight container for 4 days or freeze raw patties for up to 3 months.
What's the best way to serve these savory-sweet patties?
Pair them with cooling sides like avocado salad, cucumber-yogurt dip, or spicy sriracha mayo. For a complete meal, serve with quinoa or brown rice, or stack them in whole wheat buns for vegan sliders. The sweetness balances perfectly with tangy or spicy accompaniments.
