How to Make Hearty Lentil Walnut Stuffed Sweet Potatoes Recipe
Step 1: Steam the Sweet Potatoes
Start by steaming your sweet potatoes until they are tender and soft — about 40 minutes depending on their size. This method keeps them moist and makes sure they’re perfectly cooked for scooping out the filling later. You want them fork-tender, not mushy, so it’s just right for holding our hearty mixture.
Step 2: Sauté Onions, Garlic, and Walnuts
While the potatoes are steaming, heat olive oil in a pressure cooker or a heavy-pan. Gently sauté finely chopped onions and minced garlic until they are soft, sweet, and fragrant. Then add the chopped walnuts, allowing them to toast lightly while stirring. Toasting the nuts enhances their flavor and lends a wonderful crunch that contrasts with the creamy potatoes.
Step 3: Add Spices, Lentils, and Tomato Paste
Next, stir in the ras el hanout or your chosen spice blend to coat the walnuts, onions, and garlic with warming aromas. Then add the beluga lentils and tomato paste, stirring everything to combine. At this stage, the aromas filling your kitchen will start making you eager to dig into this hearty creation.
Step 4: Pressure Cook the Lentils
Pour in the water, season with fine sea salt, and seal your pressure cooker. Cook on high pressure for 8 minutes on a stovetop cooker or about 10 minutes in an electric pressure cooker such as an Instant Pot. This step ensures the lentils are tender yet still hold their shape, while those spices have deepened into the mixture’s core.
Step 5: Finish the Filling
After carefully releasing the pressure, stir in the tomato sauce and harissa if you want some extra heat. Let the mixture simmer gently without the lid for about 5 minutes until the lentils are fully cooked and the sauce thickens slightly. This finishing touch lets the flavors meld beautifully for a rich, savory filling.
Step 6: Stuff the Sweet Potatoes
Check your sweet potatoes by piercing them with a knife to make sure they’re downright soft. When done, transfer to plates and create a space for the filling by slicing lengthwise or scooping out a bit of the flesh. Spoon in your lentil walnut mixture generously — some spillover is a good thing here, trust me! To complete the dish, sprinkle fresh cilantro leaves and bright pomegranate seeds on top for a pop of freshness and color.

Garnishes
The right garnishes elevate this dish from hearty to outstanding. Fresh cilantro brings a subtle citrus note, while jewel-like pomegranate seeds add bursts of sweetness and a delightful crunch that complements the savory lentils. If you like a little extra heat, a dollop of harissa or a sprinkle of chili flakes on top adds excitement to each bite.
Side Dishes
While the stuffed sweet potatoes can stand alone as a satisfying meal, pairing them with a crisp green salad lightly dressed with lemon vinaigrette offers a refreshing contrast. Roasted seasonal vegetables or a simple cucumber yogurt dip can also round out your plate with complementary textures and flavors.
Creative Ways to Present
Feeling fancy or feeding a crowd? Serve these stuffed sweet potatoes halved on a large platter lined with greens, letting everyone scoop their portions with a side of spicy harissa or cooling yogurt sauce. Alternatively, you can hollow out the centers more and layer the filling with crumbled feta for a fusion twist that’s both inviting and unique.
Make Ahead and Storage
Storing Leftovers
Leftover Hearty Lentil Walnut Stuffed Sweet Potatoes Recipe stores beautifully in an airtight container in the refrigerator for up to three days. Reassemble the filling and potato before reheating for the freshest taste and texture. The flavors even deepen overnight, making it a great option for meal prep lunches.
Freezing
You can freeze the filling separately from the sweet potatoes to maintain the best texture upon reheating. Store the lentil walnut filling in a freezer-safe container or bag for up to two months. When ready, thaw overnight in the fridge and reheat gently on the stovetop or microwave.
Reheating
To reheat, if stuffed already, cover your potatoes with foil and warm them in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through. Reheating the filling on the stovetop or microwave with a splash of water or broth keeps it moist and saucy. This way, each bite stays as satisfying as when you first made it.
FAQs
Can I use other types of lentils for this recipe?
Absolutely! While beluga lentils are recommended for their texture and color, green or brown lentils can also work well. Just be mindful that cooking times may vary slightly, so adjust accordingly to avoid mushiness.
Is this recipe vegan and gluten-free?
Yes, this Hearty Lentil Walnut Stuffed Sweet Potatoes Recipe is naturally vegan and gluten-free. Just be sure your tomato sauce and any added condiments like harissa do not contain additives with gluten if that’s a concern.
How spicy is this dish if I add harissa?
Harissa adds a gentle to moderate heat depending on the amount used. Start with a small amount like 1/2 teaspoon and adjust to taste. It enhances the flavors without overwhelming the dish.
Can I prepare the filling ahead of time?
Definitely! The lentil and walnut filling can be made a day in advance and refrigerated. This makes assembling and baking the potatoes on the day you want to serve a quick and easy task.
What can I substitute for walnuts if I have a nut allergy?
If walnuts are off-limits, try using toasted pumpkin seeds or sunflower seeds to add crunch and a nutty flavor without the allergen risk. The texture adds a lovely contrast in the filling as well.

Ingredients
Sweet Potatoes
- 4 medium-large sweet potatoes
Filling
- 2 tablespoons olive oil
- 2 large yellow onions, finely chopped
- 4 cloves garlic, finely minced
- 1 cup roughly chopped walnuts
- 2 tablespoons ras el hanout (or mix of paprika, cumin, and turmeric)
- 1 cup beluga lentils (black lentils)
- 2 tablespoons tomato paste
- 2 cups water
- 1–2 teaspoons fine sea salt
- 1 cup tomato sauce
- Harissa (to taste, optional)
To Serve
- Cilantro (fresh)
- Pomegranate seeds
Instructions
- Steam the Sweet Potatoes: Begin by steaming the sweet potatoes for about 40 minutes until they are soft and easily pierced with a knife, ensuring they are cooked evenly through.
- Sauté Aromatics and Nuts: While the potatoes steam, heat the olive oil in a pressure cooker. Sauté the finely chopped onions and minced garlic until they become soft and translucent, building the flavor base for the filling.
- Toast Walnuts and Add Spices: Stir in the chopped walnuts and toast them until they start to brown lightly, then add the ras el hanout spice blend, lentils, and tomato paste, sautéing until the mixture is fragrant and well combined.
- Pressure Cook the Lentils: Pour the water into the pressure cooker and mix well with the sautéed ingredients. Season with fine sea salt, then cook under high pressure for 8 minutes if using a stovetop pressure cooker or 10 minutes if using an electric pressure cooker like an Instant Pot.
- Simmer the Filling: Perform a quick release of pressure, then stir in the tomato sauce and optional harissa for heat. Simmer gently without the lid for about 5 minutes, until the lentils are completely cooked and the sauce has thickened nicely.
- Prepare and Stuff the Sweet Potatoes: Check the sweet potatoes for doneness by piercing them with a sharp knife. Remove from the steamer and place on plates. Carefully cut a lengthwise slice to create space and spoon the lentil and walnut filling inside, allowing some filling to spill over.
- Garnish and Serve: Top the stuffed sweet potatoes with fresh cilantro leaves and pomegranate seeds to add freshness and a pop of color, then serve warm as a hearty meal.
Notes
- If you don’t have ras el hanout, a mix of paprika, cumin, and turmeric works well as a substitute.

- Adjust the amount of harissa to suit your heat preference; start with a small amount and add more gradually.
- This dish can be made vegan and is naturally gluten-free.
- Steaming the sweet potatoes preserves nutrients better than baking.
- Walnuts add a nice crunch and rich, nutty flavor complementing the lentils.
