Sautรฉing the Aromatics
First things first, grab your biggest pot. Heat up that olive oil over medium heat. Toss in your chopped onion, carrots, and celery. Let them get nice and soft, about 5 to 7 minutes. You want them to start smelling sweet and looking a little translucent. Then, add your minced garlic and give it a quick stir for just about a minute until you can really smell it. Don’t let it burn!

Combining and Simmering
Now for the easy part! Throw in those rinsed lentils, your veggie broth, the undrained diced tomatoes (don’t forget the juice โ it’s full of flavor!), and those dried herbs, thyme and rosemary. Give it all a good stir. Crank up the heat until itโs bubbling away like a happy little volcano, then turn it down to low. Pop a lid on it, but leave it a little bit cracked so some steam can escape. Let it simmer gently for about 30 to 40 minutes, or until those lentils are perfectly tender. Youโll know they’re done when theyโre soft enough to mash easily.

Seasoning and Finishing Touches
Once your lentils are tender, itโs time to make it taste amazing! Add salt and black pepper to your liking. I always taste test here because everyone likes their soup a little different. If you like your soup super thick, here’s a little trick Grandma used to do: take a spoon and gently mash some of the lentils against the side of the pot. It thickens the broth right up without needing any flour or cornstarch. Itโs perfect for spooning into those meal prep containers!
Tips for Perfect Lentil Vegetable Soup Meal Prep
Now that youโve got this delicious soup, letโs chat about making sure it stays amazing for your meal prep. A little bit of attention here goes a long, long way in keeping your future self happy. Iโve learned a few tricks over the years that make a huge difference in how well this soup stores and reheats. Itโs all about working smarter, not harder, right?
Cooling and Portioning for Storage
This is super important, folks! You absolutely *must* let the soup cool down completely before you even think about putting it into containers. Putting hot soup into plastic or glass can create condensation, which isn’t good for storage and can make stuff spoil faster. Plus, itโs just safer! Once it’s cooled, divide it into individual serving sizes. This way, you just grab one container when youโre ready to eat, and you donโt have to worry about reheating a giant pot.
Storage and Reheating Best Practices
For the fridge, airtight containers are your best friend here. This soup should be good for about 4-5 days. If youโre planning further ahead, pop it into freezer-safe containers. Itโll last a good 2-3 months in the freezer. When it’s time to reheat, either use your microwave (stirring halfway through for even heating) or pop it into a saucepan over medium-low heat on the stove until it’s warmed all the way through. Both work wonderfully to bring back that delicious, comforting flavor!
