  • pressure cooker


  • 1 tbsp olive oil
  • 2 tbsp minced garlic
  • 1.5 tsp coriander
  • 1.5 tsp cumin
  • 1 tsp curry powder
  • 0.5 tsp paprika
  • 0.5 tsp cinnamon
  • 0.5 tsp turmeric
  • 1/8 tsp nutmeg
  • 1 large sweet potato diced
  • 1.5 cup carrots diced
  • 1 large onion diced
  • 1 cup celery diced
  • 2 medium red bell peppers diced
  • 1.5 cups split red lentils
  • 6 cups vegetable broth
  • 1 lemon
  • 3 cups curly kale chopped


  • Set Instant Pot to 'Sauté.' Once hot, add olive oil. Add garlic and spices and sauté 1 minute.
  • Add diced sweet potato and saute until soft. Add diced carrots, onion, and bell pepper and sauteé for another 3 minutes or until onions are translucent. Add lentils and vegetable broth. Stir.
  • Set Instant Pot to 'Manual' (high pressure) and set the timer for 15 minutes. When the 15 minutes is up, quick release.
