Ingredients You'll Need

Before we dive into the method, let’s talk produce. Look for beets the size of tennis balls—any larger and they can be woody. If you can find them sold in bunches with the greens still attached, buy those; the greens are edible and can be sautéed for another meal. French green lentils (also called Le Puy) hold their shape and stay pleasantly peppery, but regular brown lentils work in a pinch; just shave five minutes off the simmer time so they don’t turn to mush. For the tomatoes, I favor fire-roasted crushed tomatoes for a smoky backbone, though plain diced tomatoes are perfectly acceptable. Winter squash adds body and subtle sweetness; butternut is classic, but acorn or kabocha are delicious alternatives. Finally, lacinato kale (the bumpy dinosaur kind) wilts quickly and doesn’t leach bitterness into the broth like curly kale can.

If you’re out of vegetable broth, water plus a generous glug of white miso does the trick. No almond butter? A scoop of tahini or even peanut butter lends the same creamy richness. And if beets aren’t your jam, swap in an equal weight of carrots for an orange glow instead of magenta.

How to Make Batch Cook Healthy Lentil Soup with Beets and Winter Vegetables

Prep the aromatics

Warm ¼ cup extra-virgin olive oil in a 7-quart heavy pot over medium heat. Dice 2 large onions, 4 celery ribs, and 4 carrots; add them with 1½ tsp kosher salt. Sweat 8 minutes, stirring occasionally, until the vegetables are translucent and the edges begin to caramelize. This foundational layer builds sweetness without added sugar.

Bloom the spices

Stir in 4 minced garlic cloves, 2 Tbsp grated fresh ginger, 2 tsp ground cumin, 1 tsp smoked paprika, ½ tsp coriander, and ¼ tsp cayenne. Cook 90 seconds until the mixture is outrageously fragrant. Toasting the spices in fat unlocks volatile oils and prevents dusty, raw flavors in the final soup.

Add the stars

Peel and cube 1½ lbs beets (about 4 medium) and 1 lb butternut squash. Toss them into the pot along with 2 cups rinsed French green lentils, 1 28-oz can fire-roasted crushed tomatoes, and 8 cups vegetable broth. Bring to a rolling boil, scraping the bottom to dissolve any browned bits—those caramelized flecks equal free flavor.

Simmer low and slow

Reduce heat to low, partially cover, and simmer 35 minutes, stirring twice. The lentils should be tender but intact, and the beets will stain the broth a dramatic fuchsia. If the soup looks thick, add 1–2 cups water; it thickens further as it cools.

Finish with greens and brightness

Strip 1 bunch lacinato kale from its stems and tear leaves into bite-size pieces. Stir them into the soup with 2 Tbsp almond butter and 1 Tbsp apple-cider vinegar. Cook 3 minutes more, just until the kale wilts a vibrant emerald. Taste and adjust salt; I usually add another teaspoon at this stage.

Portion for the week

Ladle the soup into heat-proof glass jars or BPA-free plastic quart containers. Cool completely, then refrigerate up to 5 days or freeze up to 3 months. I freeze 2-cup portions for solo lunches and 4-cup portions for family dinners—label with painter’s tape and a Sharpie so no mysterious UFOs (unidentified frozen objects) lurk in the back.

Expert Tips

Beet Stain Hack

Rub a little olive oil on your cutting board before slicing beets; it creates a barrier so the magenta dye doesn’t settle into the grain.

Speed It Up

Use pre-cubed squash from the supermarket and a microwave-steam pouch of beets to cut 15 minutes off prep.

Quick Thaw

Submerge frozen soup containers in a bowl of cold water for 20 minutes; the block slips right out into the pot for fast reheating.

Texture Boost

Reserve a cup of cooked lentils and stir them in at the end for pops of texture against the silky broth.

Variations to Try

Storage Tips

Let the soup cool to 70 °F within two hours of cooking to prevent bacterial growth. Divide into shallow containers so it chills rapidly. Refrigerated soup will thicken; loosen with a splash of water or broth when reheating. For freezer storage, leave ½ inch headspace in jars to allow expansion. I slip a piece of parchment directly on the surface before sealing to prevent ice crystals. Reheat gently—high heat scorches the beets and turns the broth muddy. Microwave on 70 % power, stirring every 90 seconds, or warm on the stovetop over medium-low, adding liquid as needed. The soup tastes even better on day three once the flavors meld.

Frequently Asked Questions

Absolutely. Add everything except kale, almond butter, and vinegar to the insert; cook on LOW 6–7 hours or HIGH 3–4 hours. Stir in remaining ingredients during the last 15 minutes.

Nope. French green lentils don’t contain sulfur-rich compounds that cause, ahem, digestive discord, and they cook quickly enough that soaking is unnecessary.

Press your fingernail into the skin; if it punctures easily and the flesh feels dense, you’re good. If it feels spongy or the skin is cracked and corky, compost them.

Once puréed to a smooth consistency, yes. The salt level is moderate; omit the cayenne and use low-sodium broth. Freeze in ice-cube trays for perfect toddler portions.

Because it contains lentils and squash, it’s too dense for safe water-bath canning. Use a pressure canner at 11 lbs pressure for 75 minutes (quarts) or freeze instead.
