2 garlic cloves, minced

1 large egg

2 tablespoons chopped fresh parsley

1 teaspoon ground cumin

1 teaspoon smoked paprika

1/2 teaspoon ground coriander

1/4 teaspoon black pepper

Instructions

Prepare the sweet potato

Peel and cut the sweet potato into chunks. Boil or steam until very tender, then drain well and mash until smooth. Let it cool slightly before combining with the other ingredients. Excess moisture can make Lentil Sweet Potato Patties too soft, so make sure the sweet potato is not watery.

You can also roast the sweet potato instead of boiling it. Roasting gives the mash a slightly deeper flavor and usually results in a drier texture, which helps the patties hold together.

Prepare the lentils

If using canned lentils, rinse and drain them thoroughly. Pat them dry with paper towels if they seem very wet. If using home-cooked lentils, let them cool and drain completely.

Place the lentils in a large bowl and mash about half of them with a fork or potato masher. Leave the remaining lentils whole for texture. This balance helps the patties stay firm while still giving each bite a hearty feel.

Combine the mixture

Add the mashed sweet potato, rolled oats, red onion, garlic, egg, parsley, cumin, smoked paprika, coriander, salt, black pepper, and lemon juice to the bowl.

Mix everything thoroughly until evenly combined. The mixture should be firm enough to shape. Let it rest for 10 minutes so the oats can absorb some moisture.

If the mixture is still sticky, add another tablespoon or two of oats. This step makes the mixture easier to shape and prevents the patties from falling apart during cooking.

Shape the patties

Scoop about one-third cup of the mixture into your hands and shape it into a round patty. Gently flatten it to about half an inch thick.

Continue until all the mixture is used. Try to keep each patty similar in size so they cook evenly.

If the mixture feels warm or very soft, refrigerate the shaped Lentil Sweet Potato Patties for 15 to 20 minutes before cooking. Chilling can help them firm up.

Cook on the stovetop

Heat one tablespoon of olive oil in a large nonstick or cast-iron skillet over medium heat. Add several patties, leaving enough space to flip them easily.

Cook for about four to five minutes on the first side, or until golden and lightly crisp. Flip carefully and cook for another four minutes on the second side.

Add more oil as needed for the remaining batches. Lentil Sweet Potato Patties should be browned outside and warmed through in the center.

Oven-baked method

For a lighter option, preheat the oven to 400°F or 200°C. Line a baking sheet with parchment paper and lightly brush or spray the patties with olive oil.

Bake for about 22 to 25 minutes, flipping halfway through. Baked Lentil Sweet Potato Patties will be slightly less crisp than pan-fried ones but are still delicious and easy to prepare in a large batch.

Tips

Drain the ingredients well

Too much moisture is the main reason patties fall apart. Drain the lentils thoroughly and avoid overly wet sweet potato mash.

Let the mixture rest

Resting for 10 minutes gives the oats time to absorb moisture and helps Lentil Sweet Potato Patties become easier to shape.

Do not make them too thick

Patties that are very thick may brown on the outside before the centers are fully heated. Keep them around half an inch thick for even cooking.

Flip gently

Wait until the first side has formed a firm golden crust before flipping. This gives the patties more structure and reduces the chance of breaking.

Use a nonstick surface

A nonstick skillet or seasoned cast-iron pan makes Lentil Sweet Potato Patties easier to cook.

Variations

Mediterranean version

Add crumbled feta, chopped dill, oregano, and a little lemon zest. Serve with tzatziki or cucumber yogurt sauce.

Spicy version

Add cayenne pepper, chili flakes, or finely chopped jalapeño. Heat pairs nicely with the sweet potato.

Indian-inspired version

Add curry powder, turmeric, ginger, and chopped cilantro. Lentil Sweet Potato Patties take on a warm, aromatic flavor and taste great with yogurt or chutney.

Vegan version

Replace the egg with one tablespoon ground flaxseed mixed with three tablespoons water. Let it sit for 10 minutes before adding it to the mixture.

Cheesy version

Add one-third cup shredded cheddar, Parmesan, or feta for extra richness. Cheese also helps the patties hold together.

Extra vegetable version

Add finely grated carrot, zucchini, or chopped spinach. Make sure any high-moisture vegetables are squeezed dry first.

Serve these patties with our Crusty Italian Bread for a hearty and satisfying meal.

Serving Suggestions

Lentil Sweet Potato Patties can be served in many different ways, making them useful for breakfast, lunch, or dinner. For a light meal, place them over mixed greens with cucumber, tomato, avocado, and a lemony yogurt dressing.

For a sandwich-style meal, tuck the patties into pita or wraps with lettuce, tomato, red onion, and a creamy sauce.

For dinner, serve Lentil Sweet Potato Patties with roasted vegetables, quinoa, couscous, or a simple grain bowl. A side of hummus, tzatziki, or garlic yogurt adds extra flavor without making the meal heavy.

They also reheat well for meal prep and lunchboxes.

Q&A

Can I use canned lentils?

Yes. Canned lentils are convenient and work very well. Rinse and drain them thoroughly before using so the mixture does not become too wet.

Can I make the patties ahead of time?

Yes. Shape Lentil Sweet Potato Patties up to one day ahead and store them covered in the refrigerator. Cook them when ready to serve.

Can I freeze them?

Yes. Cook the patties, let them cool completely, then freeze them in a single layer before transferring to a freezer-safe container. Reheat in the oven, air fryer, or skillet.

Why are my patties falling apart?

The mixture may contain too much moisture or may not have enough binder. Add a little more oats and let the mixture rest longer before shaping.

Can I use red lentils?

Red lentils are softer and can make Lentil Sweet Potato Patties more delicate. Brown or green lentils usually give better texture, but red lentils can work if they are well drained.

Can I make them without oats?

Yes. Breadcrumbs, almond flour, or crushed whole-grain crackers can replace the oats. Add a small amount at a time until the mixture holds together.

Can I cook them in an air fryer?

Yes. Spray lightly with oil and air fry at 375°F or 190°C for about 10 to 12 minutes, flipping halfway through.
