Ingredients

  • 1 cup dried lentils (green or brown, rinsed)
  • 2 cups low-sodium vegetable broth
  • 1 can (14 oz) diced tomatoes
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 2 medium carrots, diced
  • 1 cup chopped celery
  • 1 cup chopped bell peppers (any color)
  • 1 medium zucchini, diced
  • 1 tsp ground cumin
  • 1 tsp smoked paprika
  • 1/2 tsp dried thyme
  • Salt and freshly ground black pepper to taste
  • 1 tbsp olive oil
  • Fresh parsley or cilantro for garnish

Equipment

  • Slow cooker (4 to 6-quart capacity recommended)
  • Cutting board and knife for chopping vegetables
  • Measuring cups and spoons
  • Wooden spoon or spatula for stirring
  • Can opener for diced tomatoes
  • Serving bowls and utensils

Instructions

  1. Prepare the vegetables. Wash and dice the onion, carrots, celery, bell peppers, and zucchini. Mince the garlic cloves.
  2. Sauté aromatics (optional but recommended). In a small pan, heat olive oil over medium heat. Add the chopped onion and garlic, sauté for 3-4 minutes until fragrant and translucent. This step enhances the flavor but can be skipped for convenience.
  3. Add ingredients to the slow cooker. Place the rinsed lentils, sautéed onion and garlic, diced carrots, celery, bell peppers, zucchini, canned tomatoes (with juices), and vegetable broth into the slow cooker.
  4. Season the mixture. Add ground cumin, smoked paprika, dried thyme, salt, and pepper. Stir gently to combine all ingredients evenly.
  5. Set the slow cooker. Cover and cook on low for 6-8 hours or on high for 3-4 hours. The lentils should be tender, and the vegetables cooked through.
  6. Check seasoning and consistency. Before serving, taste and adjust salt and pepper as needed. If the stew is too thick, add a splash of vegetable broth or water.
  7. Serve and garnish. Ladle the stew into bowls and garnish with fresh parsley or cilantro for a pop of color and freshness.

Tips & Variations

“Using dried lentils instead of canned saves money and reduces added sodium, while slow cooking enhances texture and flavor.”

  • Make it a curry: Add 1 tbsp curry powder and 1/2 tsp turmeric along with the other spices for an Indian-inspired flavor.
  • Use different legumes: Substitute lentils with chickpeas or black beans for variety.
  • Bulk it up: Stir in 1 cup of cooked quinoa or brown rice in the last 30 minutes of cooking.
  • Add greens: Toss in 2 cups fresh spinach or kale during the last 15 minutes for extra nutrients.
  • Freeze leftovers: This stew freezes beautifully for up to 3 months. Portion into airtight containers for quick meals.
