Instant Pot Sambar Rice Recipe: South Indian Lentil and Veggie One-Pot

There’s something deeply satisfying about recreating traditional South Indian flavors in a modern kitchen. This one-pot dish transforms humble lentils and vegetables into a fragrant, hearty meal that’s both comforting and nutritious.

I’ve adapted the classic sambar rice recipe for the Instant Pot, preserving the authentic taste while simplifying the process. The pressure cooker infuses the lentils and veggies with bold spices, creating layers of flavor in a fraction of the time.

What emerges is a dish where tender lentils, soft vegetables, and aromatic spices come together in perfect harmony. The result is a meal that’s as convenient as it is delicious, with minimal cleanup required.

Serve it hot for a taste of South India that feels like home.

Ingredients for Instant Pot Sambar Rice

A handful of spices, lentils, rice, and fresh veggies bring this South Indian classic to life.

The toor dal is non-negotiable—it’s what gives sambar rice that authentic texture. Indian grocery stores carry it, but Patel Brothers or H-Mart are reliable for quality. Look for bright yellow lentils without any off smells. The sambar powder is your flavor backbone; MTR or Gits brands are solid. Fresh curry leaves add that restaurant-quality aroma (find them in the freezer section if not fresh).

No toor dal? Red lentils or moong dal work but cook faster—reduce water by 25%. Missing sambar powder? Combine coriander, cumin, red chili powder, and fenugreek in equal parts. Drumstick not available? Okra or zucchini hold up well. Asafoetida can be skipped, but it adds depth (use a pinch of onion powder as a very distant substitute).

Leftovers keep beautifully for 3-4 days in the fridge. The flavors deepen overnight, so this tastes even better the next day. Freezes well for up to 3 months. Reheat with a splash of water to loosen the texture.

Step-by-Step Instructions for Instant Pot Sambar Rice

This one-pot method delivers authentic flavor with minimal effort and maximum convenience.

Step 1: Rinse and Prepare the Base Ingredients

Rinse the 1 cup Toor Dal thoroughly under cold water until the water runs clear, then drain completely. I like to soak it for 10 minutes while prepping the rest—this reduces cooking time slightly.

Rinse the 1 cup Basmati Rice separately until water runs clear and drain well. Meanwhile, finely chop the 1 whole Yellow Onion and 2 whole Tomatoes, and slit the 2 pieces Green Chili lengthwise. You want everything prepped before starting the Instant Pot to maintain the one-pot promise.

Step 2: Temper the Aromatics in the Instant Pot

Set your Instant Pot to the Sauté function and add the 2 tbsp Vegetable Oil. When the oil shimmers, add the 1 tsp Mustard Seeds and 1 tsp Cumin Seeds. They’ll start to sizzle and pop within 20-30 seconds—this is your signal they’re ready.

Immediately add the 0.25 tsp Asafoetida, 8 pieces Curry Leaves, 1 tbsp Fresh Ginger, and 4 cloves Garlic Cloves. Sauté for 30 seconds until the garlic turns light golden and releases its aroma. The asafoetida will mellow out beautifully during this process.

Add the chopped Yellow Onion and sauté for 2-3 minutes until translucent. Then stir in the 2 tbsp Sambar Powder and 0.5 tsp Turmeric Powder, cooking for another 30 seconds to bloom the spices. The kitchen will smell incredible at this point.

Step 3: Combine and Pressure Cook

Add the drained Toor Dal, Basmati Rice, and 2 cups Mixed Vegetables to the pot. Stir to coat everything in the spiced oil. Pour in the 4 cups Water and add the 1.5 tsp Salt and chopped Tomatoes.

Give it a good stir, then add the slit Green Chili. Secure the lid, set the valve to Sealing, and cook on High Pressure for 6 minutes. The Instant Pot will take about 10 minutes to come to pressure first—that’s normal.

Step 4: Release Pressure and Finish

Allow the pressure to release naturally for 10 minutes, then quick-release any remaining pressure. Open the lid carefully, away from your face to avoid the steam. The Toor Dal should be soft and the Basmati Rice perfectly cooked—not mushy.

Give everything a gentle stir. If the mixture seems too thick, add a splash of hot water. Taste and adjust salt if needed. The vegetables should be tender but still hold their shape, and the sambar rice should have a porridge-like consistency that’s hearty and satisfying.

Garnish with the 0.25 cup Fresh Cilantro and serve hot. The flavors meld beautifully after sitting for 5 minutes, so don’t rush to the table.

Essential Equipment for instant pot sambar rice

Instant Pot Necessity

An Instant Pot is non-negotiable for this recipe—I use the 6-quart Duo model for perfect results every time. The pressure cooking function infuses flavors deeply while cutting traditional cooking time in half. Look for one with at least 7 pressure settings for versatility. 💪

Wooden Spoon

A good wooden spoon is essential for stirring the tempering spices without scratching your pot. I prefer a long-handled bamboo spoon that reaches the bottom easily. It also helps scrape up all those delicious browned bits during sautéing.

Measuring Tools

Precise measurements matter in South Indian cooking. Use a 1-cup dry measuring cup for the dal and rice, and a set of measuring spoons for the spices. I keep a Pyrex 2-cup measure handy for the water—it’s heatproof for easy pouring.

Fine Mesh Strainer

Rinsing the Toor Dal and Basmati Rice is crucial for removing starch and debris. A fine mesh strainer from OXO works perfectly—its tight weave prevents even the smallest lentils from slipping through. Rinse until the water runs completely clear.

Sharp Chef’s Knife

You’ll be dicing lots of vegetables, so a sharp 8-inch chef’s knife makes prep faster and safer. I use Wüsthof for its comfortable grip and precision. Pair it with a cutting board that has a groove to catch juices from the tomatoes.

Tempering Essentials

For authentic flavor, invest in a small tempering pan (or use a ladle) for the final touch. Heat 1 tbsp ghee with extra mustard seeds and curry leaves, then pour over the finished dish. This step elevates the flavors significantly. ⚡
