There’s something deeply comforting about a pot of stew bubbling away on the stove—especially when you know it’s doing double duty as both tonight’s dinner and tomorrow’s lunch. This healthy batch-cooking lentil and carrot stew with spinach greens has been my go-to for more than a decade, through graduate-school nights, new-mom exhaustion, and every flu season in between. The first time I made it, I was trying to use up a wilting bag of spinach and the last cup of green lentils in the pantry. One sniff of the cumin-laced steam rising from the pot and I was hooked for life.

Since then, I’ve scaled the recipe up to feed a crowd, down to fit my smallest saucepan, and sideways to accommodate every dietary quirk my friends and family have thrown at me (gluten-free, dairy-free, nut-free, soy-free—check, check, check, check). It’s the soup I bring to new parents, the one I freeze in muffin tins for my future self, and the bowl I crave when the weather turns grey. If you’ve never tried batch cooking, this stew is the perfect gateway: one hour of gentle simmering yields eight generous portions, each packed with 18 grams of plant protein, a rainbow of vegetables, and enough cozy flavor to make you look forward to leftovers.

Heart-healthy: Low in saturated fat, high in fiber, and naturally cholesterol-free.

Ingredients You'll Need

The beauty of this stew lies in humble ingredients that turn magical when they mingle. Look for green or French (Le Puy) lentils—they hold their shape and give a pleasant bite. Red lentils will dissolve into a creamy dal-style soup, which is delicious but not the texture we’re after here. Carrots should be firm and bright; if they’re sprouting whiskers, just peel deeply. For the spinach, grab the giant 10-ounce container at the warehouse store; it wilts down to nothing and you’ll feel virtuous every time you open the fridge.

Green lentils: Rich in iron and folate, they cook in about 25 minutes without an overnight soak. Rinse and pick out any tiny stones—unless you enjoy dental surprises. Carrots: Buy bunches with tops still attached; the greens are a freshness indicator and can be turned into pesto if you’re feeling zero-waste chic. Spinach: Baby spinach saves prep time, but mature leaves have deeper flavor. If you’re using frozen, thaw and squeeze out excess water so your stew doesn’t taste like spinach ice cubes.

Aromatics: One large yellow onion plus three cloves of garlic form the sofrito backbone. Swap in shallots if you’re out. Spices: Smoked paprika lends campfire vibes, while ground cumin adds earthy warmth. If your spices have been languishing since the last presidential administration, treat yourself to fresh jars; the difference is night and day. Tomatoes: A 28-ounce can of fire-roasted crushed tomatoes adds subtle charred notes. No fire-roasted? Add a pinch of sugar and a drop of liquid smoke to regular crushed tomatoes.

Broth: Low-sodium vegetable broth keeps things vegetarian and lets you control salt. Chicken broth works for omnivores. Water plus a bay leaf is fine in a pinch. Lemon: A squeeze at the end brightens the whole pot and balances the sweet carrots. Olive oil: Two tablespoons are enough to sweat the vegetables; save your fancy finishing oil for salad. Optional flourish: A dollop of Greek yogurt or coconut yogurt takes this into luxury territory.

How to Make Healthy Batch Cooking Lentil and Carrot Stew with Spinach Greens

Prep your produce

Dice 1 large yellow onion (about 1½ cups), peel and slice 4 medium carrots into ¼-inch half-moons (roughly 3 cups), and mince 3 garlic cloves. Rinse 2 cups (400 g) green lentils in a fine-mesh strainer until the water runs clear. Stem and roughly chop 8 cups spinach (or thaw and squeeze dry a 10-ounce box frozen).

Bloom the spices

Heat 2 Tbsp olive oil in a heavy 5- to 6-quart Dutch oven over medium heat. When the oil shimmers, add the diced onion and ½ tsp kosher salt. Sauté 4 minutes until translucent, stirring occasionally. Stir in 2 tsp ground cumin, 1 tsp smoked paprika, and ½ tsp black pepper; cook 60 seconds until fragrant—your kitchen will smell like a Moroccan souk.

Build the base

Add the minced garlic and carrots; cook 2 minutes. Pour in one 28-ounce can crushed tomatoes and scrape the bottom with a wooden spoon to deglaze any browned bits—that caramelized fond equals free flavor.

Simmer the lentils

Stir in the rinsed lentils and 5 cups low-sodium vegetable broth. Bring to a boil, then reduce to a gentle simmer. Partially cover and cook 25 minutes, stirring once or twice, until lentils are tender but still hold their shape.

Wilt in the greens

Uncover and stir in the chopped spinach (it will look like too much, but have faith). Simmer 3 minutes more until wilted and vibrant. If using frozen spinach, simmer just 1 minute to heat through.

Finish bright

Off heat, stir in the juice of ½ lemon and taste for salt. Depending on your broth, you may need an additional ½ tsp. The soup should be thick enough to coat a spoon; add a splash of water or broth if you prefer it brothy.

Portion for batch cooking

Ladle into eight 2-cup glass containers. Cool 30 minutes on the counter before refrigerating or freezing (hot glass can shatter). Leave ½-inch headspace if freezing to allow for expansion.

Serve and swoon

Reheat single portions in the microwave 2–3 minutes, stirring halfway, or simmer on the stovetop 5 minutes. Top with yogurt, a drizzle of olive oil, or crushed red-pepper flakes for heat.

Expert Tips

Toast your spices

Push the cumin and paprika around the dry pot for 30 seconds before adding oil; the heat releases volatile oils and amplifies aroma.

Double the spinach

If you plan to freeze, add only half the spinach before freezing. Stir in fresh spinach when reheating to keep color vivid.

Speed-soak lentils

Cover lentils with boiling water while you prep vegetables; drain and proceed—cuts 5 minutes off simmer time.

Silky finish

Blend 1 cup of finished stew and stir back in for a creamier texture without dairy.

Salt late

Tomatoes and broth reduce; salting at the end prevents over-seasoning.

Crunch factor

Top with toasted pumpkin seeds or homemade croutons baked with olive oil and za’atar.

Variations to Try

Moroccan twist: Add ½ tsp cinnamon, ¼ tsp cayenne, and a handful of chopped dried apricots with the tomatoes.
Coconut curry: Swap smoked paprika for 1 Tbsp mild curry powder and finish with ½ cup light coconut milk.
Protein boost: Stir in a 15-ounce can of chickpeas (drained) during the last 5 minutes.
Root-veg medley: Replace half the carrots with parsnips or sweet potatoes for a sweeter profile.
Herbaceous: Stir in ½ cup chopped fresh dill or cilantro right before serving for a green pop.

Storage Tips

Refrigerator: Cool completely, then store in airtight containers up to 5 days. The flavors meld beautifully, making day-three bowls the most coveted.

Freezer: Ladle into silicone muffin trays for single ½-cup pucks; once solid, pop out and store in zip-top bags up to 3 months. Larger portions freeze flat in quart bags to save space.

Reheat: Thaw overnight in the fridge or use the microwave’s defrost setting. Add a splash of broth or water to loosen, as lentils continue to absorb liquid.

Meal-prep pairing: Serve over quinoa, brown rice, or cauliflower rice. Pack a side of whole-wheat pita chips for dipping.
