❓ FAQ

Can I use canned lentils?
Not for this one—they’ll get mushy. Use dried lentils for the best texture.

Yes! Sauté onions/garlic, add everything to a big pot, and simmer for about 45 minutes.

Can I freeze it?
Totally! It freezes beautifully. Just cool completely and freeze in airtight containers.

🧊 Leftovers & Storage

  • Fridge: Store in a sealed container for up to 5 days.
  • Freezer: Freeze for up to 3 months. Thaw overnight and reheat on the stove or microwave.
