Ingredients

Instructions

  1. Step 1: Heat 2 tbsp vegetable oil in a large pot over medium heat. Add 1 finely chopped yellow onion and sauté for 5 minutes until translucent and fragrant. Stir in 3 minced garlic cloves and 1 tbsp grated ginger, cooking for 1 minute more.
  2. Step 2: Add 1 tsp ground turmeric, 1 tsp ground cumin, 1 tsp garam masala, and 1/2 tsp red chili powder to the pot, stirring constantly for 30 seconds until the spices bloom and release aroma.
  3. Step 3: Pour in 1 cup red lentils, 1 can (14.5 oz) diced tomatoes with their juice, and 3 cups vegetable broth. Bring the mixture to a boil, then reduce heat to low and simmer uncovered for 25 minutes until lentils are tender and the curry thickens.
  4. Step 4: Stir in 1/2 cup coconut milk and 1 tsp salt, cooking for another 5 minutes to meld flavors. Remove from heat and garnish with 2 tbsp chopped fresh cilantro before serving.
