Instructions
-
Sauté the aromatics:
Turn the Instant Pot to Sauté mode. Add olive oil, onion, garlic, carrots, and celery. Cook for 4–5 minutes until softened. -
Add spices and lentils:
Stir in thyme, oregano, paprika, and the bay leaf. Add the rinsed lentils and mix well. -
Add liquids and tomatoes:
Pour in the diced tomatoes, broth, and water. Stir everything together and secure the lid. -
Pressure cook:
Set the Instant Pot to Manual (High Pressure) for 15 minutes. Allow the pressure to release naturally for 10 minutes, then quick release any remaining pressure. -
Add greens and lemon:
Stir in spinach or kale until wilted. Add lemon juice for freshness. Taste and adjust seasoning with salt and pepper. -
Serve:
Ladle into bowls and drizzle with a bit of olive oil or sprinkle with grated Parmesan if desired.
Tips
-
Use green or brown lentils for the best texture — red lentils will become softer and thicker.
-
Add cooked sausage or shredded chicken for extra protein.
-
The soup thickens as it sits — add more broth if you prefer it thinner.
