Ingredients

1 1/2 cups brown lentils
1/2 large onion, diced
2 tablespoons red curry paste
1 tablespoon sugar (optional)
1 teaspoon garam masala
1 teaspoon curry powder
1/2 teaspoon turmeric
2 cloves garlic, minced
One 1-inch knob of ginger, minced
A few good shakes of cayenne pepper
2 cups water
One 14-ounce can tomato sauce
1 teaspoon coarse salt (more to taste)
3/4 cup coconut milk
2 tablespoons butter or ghee (optional)
Cilantro for garnishing
Rice for serving

Instructions

Combine the brown lentils, diced onion, red curry paste, sugar, garam masala, curry powder, turmeric, minced garlic, minced ginger, cayenne pepper, water, tomato sauce, and coarse salt inside the Instant Pot stainless steel inner pot.
Secure the lid and ensure the steam release valve is set to the sealing position.
Select the Manual or Pressure Cook setting and adjust the timer to fifteen minutes on high pressure.
Once the cooking cycle concludes, allow the unit to remain untouched for a natural pressure release lasting ten minutes.
Carefully release any remaining steam by turning the valve to the venting position, then open the lid.
Pour in the coconut milk and add the butter or ghee, stirring the mixture until the fat has melted and the sauce is creamy and unified.
Taste the curry and add additional salt or seasonings if needed.
Ladle the lentils over warm rice and finish with a scattering of fresh cilantro before serving.

Step-by-Step Details

Preparing the Pot

When adding the initial ingredients, focus on the layering to ensure even cooking. Some users find that pouring the tomato sauce on top of the other ingredients without aggressive stirring can help prevent the “burn” warning, as the sauce is thick and contains sugars that can stick to the bottom. Ensure the ginger and garlic are finely minced so they melt into the sauce during the high-pressure phase.

Setting the Pressure

Confirm the sealing ring is properly seated in the lid before locking it into place. The Instant Pot will take roughly ten minutes to come to full pressure before the fifteen-minute countdown begins. During this time, the aromas of the red curry paste and turmeric will begin to develop.

The Release Phase

The ten-minute natural release is a vital part of the cooking process for Instant Pot Red Curry Lentils. This period allows the lentils to finish softening and prevents the liquid from spraying through the steam valve, which often happens with starchy legumes if the pressure is released too quickly.

Finishing the Sauce

The final addition of coconut milk and butter is what creates the signature “restaurant-style” texture. The lentils should be tender but still hold their shape. If you prefer a thinner consistency, you can stir in a splash more water or coconut milk. The residual heat of the lentils is sufficient to melt the butter or ghee instantly.

Pro Tips

Lentil Selection: Stick specifically to brown or green lentils for this recipe. Red lentils have a much thinner skin and will break down into a puree if cooked for fifteen minutes under pressure.¹
The Sauté Shortcut: If you have an extra five minutes, you can sauté the onion, garlic, and ginger in a teaspoon of oil using the sauté function before adding the other ingredients to deepen the base flavors.
Managing the Burn Sign: If your model is particularly sensitive, stir the water and spices together first, then add the lentils and onion, and finally pour the tomato sauce on the very top without stirring it in.
Ginger Freshness: Use a spoon to peel your ginger knob quickly and a microplane to mince it into a paste for the most even distribution of flavor.
Fat Matters: While the butter or ghee is optional, it adds a specific richness that balances the acidity of the tomato sauce.²
Spice Control: The heat in this dish comes primarily from the red curry paste and the cayenne. If you are sensitive to spice, start with one tablespoon of curry paste and omit the cayenne.

Variations or Substitutions

Vegan Adaptation: To keep the dish entirely plant-based, simply omit the butter or ghee, or replace it with a vegan butter alternative or extra coconut milk.
Greens Addition: Stir in two cups of fresh baby spinach or chopped kale during the final step. The heat from the lentils will wilt the greens in about sixty seconds.
Root Vegetable Boost: Add one cup of finely diced sweet potatoes or carrots to the pot before pressure cooking for added natural sweetness and texture.
Alternative Aromatics: If you cannot find red curry paste, you can increase the curry powder and garam masala, though the flavor profile will shift from Thai-inspired toward a more traditional Indian dal.

Serving Suggestions

Grains and Bases: While basmati or jasmine rice is the standard pairing, these lentils are excellent served over quinoa or with a side of toasted naan or garlic pita bread.
Fresh Toppings: Beyond cilantro, a squeeze of fresh lime juice right before eating can brighten the earthy flavors of the lentils.
The “Fridge Clean-Out” Bowl: Follow the suggestion of adding roasted bell peppers, sliced mango, or avocado chunks to turn a single bowl into a nutrient-dense meal.
Cooling Element: A dollop of plain Greek yogurt or a dairy-free coconut yogurt on top can help temper the heat for those who find the red curry paste intense.³

FAQs

Can I use red lentils instead of brown?

Red lentils cook much faster and lose their structure easily. If you use them, you should reduce the high-pressure cooking time to approximately five to ten minutes to avoid a mushy consistency.

Is it possible to freeze the leftovers?

Yes, this recipe is excellent for freezing. You can freeze the cooked lentils in airtight containers for up to three months. Alternatively, you can freeze the dry ingredients and aromatics together in a bag for a “dump-and-go” freezer meal.

What should I do if the lentils are too watery after cooking?

If the consistency is thinner than you like after the pressure release, use the sauté function for two to three minutes after adding the coconut milk to simmer off some of the excess moisture.

Why did I get a “burn” notice on my Instant Pot?

This usually happens if the tomato sauce or spices settle at the bottom and scorch. Ensure there is enough thin liquid (water) at the bottom before adding the thicker tomato sauce on top.
