Substitutions and Variations
Want to change the texture or flavor? Try these swaps:
- Lentils: Red or yellow lentils give a creamy texture. Green or brown lentils will hold their shape and need slightly longer cooking, resulting in a chunkier soup.
- Cumin: Use ground cumin if you don’t have seeds — about 2 teaspoons ground for 1 tablespoon seeds.
- Coconut milk: Optional, but it adds creaminess and tames the spices. Other plant milks can be used but will be thinner.
- Heat: Add cayenne, red pepper flakes, or sliced chilies for spice.
How To Make Potato and Lentil Soup
Step 1: Heat oil in a large Dutch oven or soup pot over medium heat. Add the cumin seeds and toast for 1–2 minutes, watching carefully so they don’t burn.
Step 2: Add onion, garlic, and ginger. Cover and cook over medium-low heat for 2–3 minutes until the onion softens.
Step 3: Add the cubed potatoes and red lentils, stirring so they’re coated with oil and spices. Pour in the vegetable broth and bring to a gentle simmer.
Step 4: Cover and simmer over medium-low heat for 15–20 minutes, until potatoes and lentils are very soft. Season with salt, black pepper, and turmeric to taste. Stir in coconut milk if using. For a smoother texture, blend with an immersion blender or a regular blender in batches until you reach your preferred consistency.
Top tip: You can serve this soup chunky or blended — both versions are delicious. If you use green or brown lentils, the soup holds up better served chunky.
Toni’s Tips
- Add coconut milk for extra creaminess.
- Puree gently: Pulse the blender to keep some texture if you prefer not to make it completely smooth.
- Adjust seasoning to taste before serving.
- Serve with: Cornbread or focaccia for a satisfying meal.
FAQs
Lentils do not need to be soaked before cooking; they cook quickly and can be added directly to the pot.
Any lentil can work, but red and yellow lentils break down more easily and create a creamier soup. Green and brown lentils stay firmer and suit chunkier soups.
How to Store
- Make ahead: Cool the soup completely before transferring to airtight containers. Portion for easy meals.
- Storage: Refrigerate up to five days or freeze up to three months.
- Reheat: Thaw frozen soup in the fridge overnight, then warm on the stove for 5–8 minutes over medium heat. Microwave smaller portions until hot. If the soup thickens during storage, thin with additional broth, coconut milk, or water.
