The sweet potatoes are roasted until tender with a caramelized edge, while the lentil-rice mixture is seasoned with mustard seeds, curry leaves, and a touch of asafoetida for that unmistakable South Indian flavor.

The sweet potatoes are the heart of this dish—pick firm, vibrant orange ones at Whole Foods or your local Indian market. If they're small, grab two; if large, one will do. For the lentils, moong dal is traditional, but toor dal works too. The rice should be long-grain and unbroken—basmati or jasmine both work perfectly. Asafoetida (hing) is non-negotiable for that signature South Indian aroma—find it in the international aisle or online. I always buy Madhur or Everest brand spices for consistency, but any good quality will do. The curry leaves? Fresh is best, but dried leaves in a pinch work too—just double the amount.
No mustard seeds? Swap for 1/4 tsp mustard oil if you're feeling adventurous, but the flavor will differ slightly. Short on coconut oil? Vegetable or peanut oil works in a bind. The ghee can be omitted entirely for a dairy-free version—just use extra coconut oil. For the chili, adjust to heat preference: 1-2 whole dried red chilies for mild, 3-4 for medium heat. The turmeric and cumin should be freshly ground if possible—toast the cumin seeds first for that nutty depth. And that crispy top layer? It's all about the ghee—don't skip it if you want that perfect texture.
This dish tastes even better the next day—make extra and store in an airtight container for 3-4 days in the fridge. For freezing, portion into containers with a layer of oil on top to prevent drying. Reheat gently on the stove with a splash of water—microwaving makes it soggy. The crispy top layer is delicate, so cover it with foil while reheating. Leftovers? Perfect for lunches or pack for work—just reheat and garnish with fresh cilantro. The flavors deepen overnight, so plan ahead!
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe—just boil the sweet potatoes and rice together, then toss in the dal and spices. No separate pots, no extra cleanup. The lentils soften right in the same pot where the potatoes steam, and that curry leaf aroma fills the whole kitchen. Honestly, it’s the kind of meal that makes me feel like I’ve earned my dinner.
- Creamy-Spiced Comfort: That caramelized sweet potato mixed with split moong dal? It’s like a hug in a bowl. The mustard seeds sizzle first, then the curry leaves bloom—sharp, earthy, and just a little smoky—while the dal turns into this velvety, slightly sweet porridge. My kids ask for it by name now, and I’ll take that over any "gourmet" dish.
- Lunchbox Hero: Between us, this is my go-to for meal prep. Cook a big batch on Sunday, and I’ve got three days of lunches covered—no reheating required. The rice stays fluffy, the dal keeps its texture, and the sweet potatoes hold their shape. Pack it in containers, and it’s ready to grab before work or school. (Yes, even on a Tuesday night.)

Even better the next day. I’ll be real: I’ve made this recipe stretch into five meals without breaking the bank, and the taste never lets me down.
Step-by-step instructions for sweet potato pulusu
Here's how to create this comforting South Indian dish with a perfectly crispy topping every time.
Cook the Sweet Potatoes and Rice-Lentil Mixture
Peel and cube the 2 whole medium sweet potatoes into even 1-inch pieces. In a large pot, combine the cubed sweet potatoes, 1 cup long-grain white rice, 0.5 cup split yellow lentils (moong dal), 0.25 teaspoon turmeric powder, 1.5 teaspoons salt, and 2.5 cups water. Bring to a boil over medium-high heat, then reduce to a simmer and cook for 15-18 minutes until the sweet potatoes are tender and the rice-lentil mixture is cooked through. You'll know it's ready when the sweet potatoes pierce easily with a fork and the rice is fluffy.
Here's the thing—don't drain the mixture after cooking. The starchy water is essential for binding the dish together. Once cooked, remove from heat and let it sit covered for 5 minutes. This resting period allows the flavors to meld and the sweet potatoes to absorb any remaining liquid, creating a more cohesive texture.
Prepare the Tempering
In a small pan, heat 3 tablespoons coconut oil over medium heat. Add the 0.25 teaspoon cumin seeds and let them sizzle for 30 seconds until they turn golden and fragrant. Add the 2 whole dried red chilies and 8 curry leaves, cooking for another 30 seconds until the chilies darken slightly and the curry leaves release their aroma.
This is where the magic happens. Immediately add the 0.5 teaspoon mustard seeds and 0.125 teaspoon asafoetida (hing). The mustard seeds will pop dramatically, and the hing will release its distinctive, slightly sulfuric aroma. Pour this tempering mixture over the cooked sweet potato and rice-lentil mixture, stirring gently to combine. The hing is essential—it's what gives pulusu its authentic flavor profile, so don't skip it.
Create the Crispy Topping
In a separate small pan, heat 1 tablespoon ghee (or coconut oil for dairy-free) over medium heat. Add the 0.25 cup chopped fresh cilantro and let it crisp up for 2-3 minutes until the edges turn golden brown. Remove from heat and immediately sprinkle this cilantro mixture over the sweet potato pulusu.
For the crispy topping, spread the entire mixture evenly in a greased rectangular baking dish. Using the back of a spoon, create a textured surface with small ridges—this maximizes surface area for crisping. The key to that perfect crispy top is patience. Bake at 375°F for 15-20 minutes until the top is deep golden brown and crispy to the touch. Real talk: don't peek too often or you'll steam it instead of crisping it.
Serve Warm with Fresh Accompaniments
Let the pulusu rest for 5 minutes after baking. This resting period allows the crispy top to set properly and makes it easier to serve. Cut into diamond shapes or serve directly from the baking dish. The contrast between the soft, flavorful sweet potato mixture and the crispy top is what makes this dish so satisfying.
Serve immediately with a dollop of yogurt or a side of pickled vegetables. The crispy top should shatter slightly when you cut into it, revealing the soft, spiced sweet potato mixture beneath. Each bite delivers that perfect textural contrast—crispy, warm, and comforting all at once. This is why pulusu makes such a comforting meal, especially during cooler months.
Pro Tips For Making Sweet Potato Pulusu
- COOK SWEET POTATOES UNTIL SOFT: I learned this the hard way—undercooked sweet potatoes turn your pulusu into a mushy, unappetizing mess. Boil or steam them until they pierce easily with a fork (about 15-20 minutes for medium potatoes), then let them cool slightly before peeling. Cold potatoes handle pressure better and won’t fall apart when tempering.
- PEEL AND CUBE SMALL: Large chunks of sweet potato take forever to cook and leave uneven texture in your pulusu. Cut them into 1-inch cubes—small enough to soften quickly but big enough to hold shape. (Yes, even if you’re impatient like me, trust the process.)
- TEMPER MUSTARD SEEDS LOW: High heat burns mustard seeds before they pop, ruining the aromatic base of your dish. Start with medium heat, then add oil and let the seeds sizzle gently for 10 seconds before tossing in curry leaves. This keeps their flavor intact and prevents bitter overcooking.
- PRESSURE-COOK DAL AND RICE TOGETHER: Skip the separate cooking—this is where the magic happens. Combine soaked moong dal, rice, and sweet potatoes in the pressure cooker with 3 cups water (adjust for your pot). The dal and rice cook simultaneously, saving 20 minutes and ensuring even texture. (Your future self will thank you.)
Storing and reheating your sweet potato pulusu
Fridge Storage Tips
Store your sweet potato pulusu in an airtight container for up to 4 days in the refrigerator. The crispy top layer will soften slightly but remains delicious when reheated properly.
I always transfer it to a glass container with a tight-sealing lid to maintain freshness. The flavors actually deepen overnight, making leftovers taste even better the next day! 🌱
Freezer Preparation
For longer storage, portion the pulusu into freezer-safe containers with a thin layer of coconut oil on top to prevent drying. Label with the date and store for up to 3 months.
The oil creates a protective barrier that preserves the crispy texture better than plastic wrap. When ready to eat, thaw overnight in the fridge for best results. 🧊
Reheating Stovetop
My preferred method is stovetop reheating to preserve texture. Cover the pulusu with a damp paper towel and heat over low-medium heat for 8-10 minutes, stirring occasionally. Add 1-2 tablespoons of water if it looks dry.
The crispy top will soften but still provide satisfying texture. For extra crispiness, broil for 2-3 minutes at the end. 🔥
Microwave Method
If you're short on time, microwave reheating works in a pinch. Cover with a damp paper towel and heat on 50% power for 2-3 minutes, stirring halfway. The result won't be as crispy, but it's still flavorful.
For better texture, transfer to a baking dish and broil for 1 minute after microwaving. This two-step approach helps restore some of the crispiness. ⚡
Crispy Top Rescue
The crispy top is delicate after storage. To revive it, sprinkle 1 teaspoon of water over the surface before reheating, then broil for 3-4 minutes until golden again.
For extra crunch, top with toasted cumin seeds or fried shallots before serving. This trick works wonders for restaurant-quality results at home. 💫
Portioning Secrets
Divide the pulusu into individual serving containers before storing to make reheating easier. Each portion should be about 1 cup for a single serving. When reheating, focus on one portion at a time to maintain even temperature and texture.
This method ensures every bite is perfectly heated and ready to enjoy. 🍽️

Frequently asked questions
Can I substitute regular potatoes for sweet potatoes in this recipe?
While you can use regular potatoes, sweet potatoes add a natural sweetness and creamier texture that's essential to this dish. For the best results, stick with sweet potatoes—they caramelize beautifully during cooking and complement the spiced lentil-rice mixture perfectly. If you must substitute, use yams as a closer alternative.
Why does my pulusu not develop a crispy top layer?
The crispy top comes from proper baking technique. Spread the mixture evenly in your dish and create texture with the back of a spoon before baking. Use 375°F heat and avoid opening the oven door too often—steam prevents crisping. A light layer of ghee or oil helps too!
What makes this dish different from regular South Indian pulusu?
This version incorporates sweet potatoes, which add natural sweetness that balances the earthy lentils and rice. Traditional pulusu uses only rice and lentils, but the sweet potato adaptation creates a more satisfying, hearty dish with beautiful color contrast. The tempering remains the same authentic South Indian technique.
Can I make this recipe without asafoetida (hing)?
While asafoetida gives pulusu its signature umami depth, you can omit it if unavailable. For a substitute, try 1/4 tsp garlic powder or 1/8 tsp onion powder—though the flavor won't be identical. The dish will still taste delicious but will lack that distinctive South Indian aroma.
How do I adjust the spice level for kids?
Reduce the dried red chilies to 1 whole chili or remove them entirely. For extra mildness, strain out the curry leaves after tempering. The mustard seeds and cumin still provide great flavor without heat. Always taste the tempering before pouring it over the main mixture!
