Tips & Variations

“For an even richer flavor, try browning your vegetables using the sauté function before slow cooking. It adds a wonderful depth to the final dish.”

  • Adjust the spice levels to your preference. Add more chili flakes or fresh jalapeño for heat, or omit them for milder dishes.
  • Use vegetable broth low in sodium to better control salt content.
  • For a vegan version of the ratatouille, serve with crusty bread or over rice instead of cheese or cream-based sides.
  • Feel free to swap lentils for beans like black beans or cannellini in the stew for different textures.
  • Add a splash of lemon juice or a dollop of yogurt (dairy or plant-based) to brighten flavors before serving.
  • Store leftovers in an airtight container in the fridge up to 4 days or freeze for longer storage.
