Ingredients for Instant Pot Spiced Red Lentil Sweet Potato Soup

Ingredients List:

1 tablespoon coconut oil
Use high-quality organic coconut oil for better flavor and health benefits.
1 medium onion, diced
A yellow onion works well here, providing a balanced sweetness.
2 garlic cloves, minced
Fresh garlic elevates the overall taste; don’t skimp on this!
1 1/2 tablespoons freshly grated or minced ginger
You can use ginger paste in a pinch, but fresh is king for zing.
1 serrano pepper, diced (optional)
Add more or less depending on your spice tolerance.
2 teaspoons garam masala
A flavorful spice blend; I prefer Brand X for its depth and richness.
1 teaspoon curry powder (optional)
Curried flavors can take leadership—try Brand Y for authentic taste!
1 teaspoon ground cumin
Integral for that warm, earthy flavor; look for high-quality cumin.
1/2 teaspoon ground turmeric
Not only for color but for health benefits, too!
2 medium sweet potatoes, peeled and cut into large dice
Choose firm, blemish-free sweet potatoes for the best texture.
1 cup red lentils, rinsed until the water runs clear
Make sure to rinse to eliminate bitterness!
4 cups low-sodium vegetable broth
Homemade if you have time, or use a quality store-bought version.
1 1/4 teaspoons sea salt + more to taste
Adjust to your preference; flavored broths may require less.
Freshly cracked black pepper
Always season with freshly cracked for better flavor.
1-2 teaspoons maple syrup (optional)
Adds a lovely counterbalance to the spices; use pure maple if you can.
Coconut yogurt (for serving, optional)
A drizzle of coconut yogurt adds creaminess and a touch of tang.
Fresh cilantro (for serving, optional)
Chopped cilantro makes for a delightful garnish and adds freshness.
Flatbread or rice (for serving, optional)
Perfect for soaking up every drop of soup!

Step-by-Step Instructions

Sauté the Aromatics: Select the Sauté setting on your Instant Pot and heat the coconut oil. Once shimmering, add the diced onion and cook for 3-4 minutes, stirring occasionally, until softened and translucent.
Chef’s Tip: Make sure not to rush this step, as it builds a flavor base!
Add Spices & Ginger: Introduce the minced garlic, grated ginger, serrano pepper (if using), garam masala, curry powder (if using), cumin, and turmeric. Stir for about 30 seconds until aromatic, allowing the spices to bloom.
Deglaze with Broth: Pour in the vegetable broth and scrape up any browned bits from the bottom. This step is crucial as it adds depth to the soup.
Combine Ingredients: Add the rinsed red lentils, diced sweet potatoes, sea salt, and black pepper. Stir well to combine everything, ensuring the lentils and sweet potatoes are fully immersed in the broth. Select Cancel to stop the sauté function.
Pressure Cook: Secure the lid on the Instant Pot, making sure the pressure release valve is sealed. Select the Pressure Cook setting and cook at high pressure for 10 minutes.
Release Pressure: Once the time is up, allow the pot to naturally release pressure for 10 minutes. Afterward, carefully switch the release valve to Venting to release any remaining pressure. Remove the lid, taking care as the steam escapes.
Final Seasoning: Stir the soup well and taste. Adjust seasoning with more salt or maple syrup if desired.
Serve: Ladle the warm soup into bowls and top with coconut yogurt and fresh cilantro, served alongside flatbread or rice as desired.
Common Mistake to Avoid: Don’t rush the natural pressure release—this helps prevent splattering and ensures the lentils don’t overcook.

Expert Tips & Tricks

Storage Recommendations: Store leftover soup in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze it in portions for up to 3 months.
Make-Ahead Instructions: Feel free to prep your veggies ahead of time! Chop onions, slice garlic, and dice sweet potatoes on a Sunday for quick assembly during the week.
Troubleshooting: If your soup is too thick after cooking, simply stir in a splash more vegetable broth or water until you reach your desired consistency. On the flip side, if it’s too thin, you can thicken it by pureeing a portion of the soup with an immersion blender.
Spice Level Adaptation: If you want a milder version, skip the serrano pepper and adjust the spices gradually. You can always add more, but it’s tough to lessen heat once it’s there.

Serving Suggestions

This Instant Pot Spiced Red Lentil Sweet Potato Soup can be served with a variety of accompaniments for a complete meal.

For special occasions, consider hosting a soup night! Lay out bowls of toppings like crispy fried onions, diced avocado, or toasted seeds for guests to customize their servings. Whether you’re entertaining or enjoying a quiet dinner, this soup can fit every mood.

Variations & Substitutions

Flavor Combinations: Experiment with adding vegetables like carrots, spinach, or kale. For an extra pop of flavor, try stirring in lime juice right before serving.
