Grandma’s Lentil Soup

lentil soup

I am finally back in San Francisco after a long flight from Germany – and I have no food in my fridge! Does somebody want to go grocery shopping for me so I will just wake up and my fridge will be full? Waa! We were so lucky to eat at many restaurants and enjoy several four-course dinners, but I definitely missed cooking over the past 2 weeks while we were on vacation. One of my favorite soups to make in the winter is my Grandma’s lentil soup recipe. She used to always make it for me when I was in college, and I would stock up my freezer. Her lentil soups were a lifesaver during finals week. If it wasn’t for those lentil soups, I would have probably made due with take-out and chocolate every day during my finals. Thanks Grandma for always making sure I was eating healthy during my college years! Now that I don’t get to go back home too often, I asked her for her lentil soup recipe and make it myself. It continues to help me during my busy weeks as school, since you can make a large batch and store it for weeks. I love adding a lot of vegetables, and lentil soup is high in fiber. My grandma soaks the lentils in water overnight, then drains them the next day before preparing the soup as the recipe directs. I also add garlic to my soup (this was not in her original recipe).

    Kristiiiii this soup saved our lives last week. For real. We had basically no food in the house except carrots, celery, onion and lentils and then I remembered seeing this soup on here. And boom. Dinner (and lunch, plus leftovers for later this week. made a ton!) was served.

    Thanks to you and your Grandma for this brilliant recipe – I must have made it 30 times already and there’s currently a huge vat of it on my stove ready to freeze for my baby and toddler. It’s almost convinced my family I can cook… 🙂
