• Broth: A good-quality vegetable broth makes a huge difference. I usually grab Imagine Organic Vegetable Broth for extra depth.

Kitchen Equipment Needed

• Crockpot/Slow Cooker – The star of this crockpot vegetable stew; I love my 6-quart Crock-Pot for even cooking.
• Cutting Board – Essential for chopping all those colorful vegetables; I use a sturdy bamboo one.
• Chef’s Knife – A sharp knife makes prep quick and safe; my favorite is a Wüsthof 8-inch chef’s knife.

• Wooden Spoon or Silicone Spatula – Perfect for stirring without scratching your crockpot.
• Ladle – Makes serving your brown lentil soup effortless and mess-free.

Instructions

Step 1: Prep the Vegetables

• Peel and dice the carrots, sweet potato, zucchini, and butternut squash into roughly 1-inch cubes so they cook evenly.
• Chop the onion and mince the garlic.
• Dice the bell peppers and roughly chop the kale or spinach.
  Pro tip: Keep vegetables roughly the same size—this helps everything cook evenly in your crockpot vegetable stew.

Step 2: Rinse the Lentils

• Place 1 cup of brown lentils in a fine-mesh strainer and rinse under cold water.
• Remove any tiny stones or debris if needed.
  Pro tip: Rinsing removes excess starch and helps your lentils cook into a perfect tender texture without sticking together.

Step 3: Sauté the Aromatics (Optional but Recommended)

• In a small pan, heat 2 tbsp olive oil over medium heat.
• Sauté the onion and garlic until fragrant and slightly golden, about 3–4 minutes.
• Add 1 tsp smoked paprika, 1 tsp cumin, and ½ tsp cinnamon, stirring for 30 seconds to bloom the spices.
  Pro tip: Blooming the spices like this deepens the flavor of your vegetable stew recipe.

Step 4: Assemble in the Crockpot

• Add all the diced vegetables, sautéed aromatics, and rinsed lentils to the crockpot.
• Pour in 4 cups vegetable broth and 1 can diced tomatoes.
• Season with ½ tsp black pepper and 1 tsp salt (adjust later if needed).
• Stir everything gently to combine.

Step 5: Cook the Stew

• Cover and cook on low for 6–7 hours or high for 3–4 hours until lentils and vegetables are tender.
• Check halfway through and give it a gentle stir to make sure nothing sticks.
  Pro tip: If the stew looks too thick near the end, add a splash of broth or water to reach your desired consistency.

Step 6: Add the Greens and Adjust Seasoning

• About 15 minutes before serving, stir in the kale or spinach.
• Taste and adjust salt and pepper if needed.
• Optional: squeeze in a bit of lemon juice for brightness.

Step 7: Serve and Garnish

• Ladle into bowls and garnish with fresh parsley and a drizzle of olive oil if desired.
• Pair with crusty bread or a side salad for a full, cozy meal.

Tips and Tricks for Success

• Cut vegetables evenly – Ensures everything cooks at the same rate and prevents mushy or undercooked pieces.
• Rinse lentils thoroughly – Removes dust and prevents your brown lentil soup from getting cloudy.
• Don’t overfill the crockpot – Leave a little space at the top for even cooking and bubbling.
• Stir halfway through cooking – Helps flavors blend and prevents lentils from sticking to the bottom.
• Add greens at the end – Keeps them vibrant and fresh instead of turning dark and wilted.
• Adjust seasoning at the end – The flavors deepen as it cooks, so taste before adding extra salt or spices.

Ingredient Substitutions and Variations

• Lentils: Swap brown lentils for green or red lentils, but adjust cooking time slightly.
• Vegetables: Use whatever you have on hand—pumpkin, parsnips, or green beans work beautifully.
• Greens: Spinach, Swiss chard, or even frozen kale are great alternatives.
• Spices: Add a pinch of chili flakes or smoked paprika for a spicier twist.
• Broth: Chicken or mushroom broth can be used if you don’t have vegetable broth.
• Protein boost: Add cooked beans, chickpeas, or cubed tofu for extra heartiness.

Serving Suggestions

• I love serving this crockpot vegetable stew with warm, crusty bread for dipping—it makes every bite feel cozy and indulgent.
• Spoon it over a bed of cooked quinoa or brown rice for a hearty, filling meal that’s perfect for lunch or dinner.
• Pair it with a light green salad and a drizzle of olive oil—it balances the richness beautifully.
• Top with a dollop of plain yogurt or sour cream for a creamy twist that complements the spices.
• Serve alongside roasted garlic or herbed flatbread to soak up every bit of the flavorful broth.

Storage and Reheating Instructions

• Refrigerator: Store leftover stew in an airtight container for up to 4–5 days.
• Freezer: Cool completely and freeze in portioned containers for up to 3 months.
• Reheating: Warm gently on the stovetop over medium heat, stirring occasionally, or microwave in a covered dish until heated through.
• Consistency tip: If the stew thickens too much after storing, stir in a splash of broth or water when reheating.
• Flavor tip: Stews often taste even better the next day as the flavors continue to meld—so don’t hesitate to make extra!
