A meatless bag of chopped vegetables and spices; lentils and broth go in on the day, spinach at the end.

Ingredients

  • In the bag: 2 carrots and 2 celery ribs, diced

  • In the bag: 1 onion, diced

  • In the bag: 3 cloves garlic, minced

  • In the bag: 1 can (14.5 oz) diced tomatoes

  • In the bag: 2 tsp cumin

  • In the bag: 1 tsp smoked paprika

  • In the bag: 1 tsp salt

  • Day of: 1½ cups dry brown or green lentils, rinsed

  • Day of: 6 cups vegetable broth

  • Day of: 3 cups baby spinach

  • To serve: lemon wedges, crusty bread

  • 1 gallon-size freezer bag

  • Permanent marker for the label

  • Salt and black pepper to taste

Directions

  • Label the bag with the recipe, date, cook time and day-of additions before you fill it.
  • Put the vegetables, garlic, tomatoes, and spices in a gallon freezer bag. Press out the air, seal, and freeze flat.
  • The day before, move the bag to the fridge.
  • Empty the bag into the crockpot and add the lentils and broth.
  • Cook 6–8 hours on LOW, until the lentils are tender.
  • Stir in the spinach, let it wilt for a few minutes, and serve with lemon.
  • Bite a lentil to confirm it is tender; if it still has a core, give it 30 more minutes.
  • Let the pot rest 10 minutes with the lid off so the sauce settles.
  • Cool leftovers within 2 hours and refrigerate in shallow containers for up to 4 days.

Notes

    Dry lentils keep in the pantry. They go in on the day with the broth, not in the bag.

Why this lentil soup holds up

Brown or green lentils keep their shape through a long cook, which is why they go in on the day and not in the frozen bag. Red lentils would melt into mush by hour four. The spinach waits until the end so it stays green and silky instead of turning to olive threads.

A squeeze of lemon right before eating is not optional. It wakes up a pot of earthy, mild flavors.

Swaps for Healthy Lentil Vegetable Soup, and one to skip

Kale or chard can replace the spinach if you add it 20 minutes earlier, since the leaves are tougher. A diced sweet potato stands in for one carrot nicely. Do not swap in red lentils or split peas, because they break down completely and you get porridge.

Serving and storing the leftovers

Serve with a thick slice of toasted bread and a little olive oil on top. The soup thickens as it sits, so loosen it with a splash of water when you reheat it on the stove. Portions freeze well in jars with an inch of headroom.

The usual mistake is adding salt to the pot early and wondering why the lentils stay firm. Taste at the end instead.

Hi, I'm Iren Pavlenko. I read the top-ranked slow cooker recipes for a dish side by side and write down what they disagree on and what they all leave out — the cut, the pot size, and both the LOW and HIGH times. I write these guides so your weeknight dinner doesn't turn into a dry roast because a recipe never said which of those four things mattered.
