Step-by-Step Instructions
- Sauté. Set the Instant Pot to sauté mode. Heat the olive oil and cook the onion, carrots, and celery for 4 to 5 minutes until softened. Add the garlic and spices and cook 1 minute more.
- Add everything else. Stir in the lentils, broth, and diced tomatoes. Scrape the bottom of the pot to lift any browned bits.
- Pressure cook. Lock the lid, set to high pressure for 12 minutes. When done, do a quick release carefully.
- Finish. Stir in the spinach until wilted. Season with salt and pepper to taste.
- Serve. Ladle into bowls with a squeeze of lemon if you like a bright finish.
Tips
- Rinse the lentils well to remove dust and reduce foaming during cooking.
- If you prefer a smoother soup, blend a portion of it and stir it back in.
- Red lentils cook into a thicker, creamier soup than green or brown ones.
Storage
Keeps in the fridge for 5 days and freezes well for up to 3 months. The soup thickens as it sits; thin it with a splash of broth when reheating.
