A nourishing bowl of slow-cooked lentil soup brings warmth and satisfaction with every spoonful. Tender legumes, fresh vegetables, and aromatic seasonings simmer together to create a hearty meal that fills the kitchen with welcoming aromas. This recipe transforms everyday pantry ingredients into something special with minimal hands-on effort.

Key Ingredients & Shopping Guide

  • Lentils: Brown or green varieties maintain texture best during long cooking. French lentils are also suitable but require extended time.
  • Fire-Roasted Tomatoes: Provides natural smokiness. Select brands with deep color and no added seasonings.
  • Smoked Paprika: Traditional Spanish paprika delivers authentic smoky notes.
  • Parmesan Rind: While optional, it enriches the broth with savory depth.
  • Fresh Vegetables: Select firm, fresh carrots, celery, and onions.
  • Red Wine Vinegar: Quality vinegar brightens the finished soup.

Preparation Method

Step 1: Prepare the Base
Heat olive oil in a skillet until shimmering. Sauté diced onions until translucent to create the flavor foundation.
Step 2: Layer the Aromatics

Step 3: Transfer to Slow Cooker
Move sautéed mixture to crockpot. Add lentils, tomatoes, broth, Parmesan rind, and bay leaf. Stir gently to combine.
Step 4: Slow Cook

Ingredients

→ Vegetables

01 1 medium yellow onion, chopped into small cubes
02 4 medium carrots, sliced into half-inch pieces after peeling
03 3 celery stalks, sliced thinly
04 4 garlic cloves, finely chopped

→ Pantry Items

05 1 can (15 ounces) of crushed tomatoes
06 15 ounces (1 can) of fire-roasted diced tomatoes
07 1 1/2 cups of green or brown lentils, the French variety
08 4 cups of veggie broth with less salt
09 2 tablespoons of good-quality olive oil

→ Seasonings

10 1 tablespoon of red wine vinegar
11 1 teaspoon of smoked paprika
12 1 teaspoon of coarse kosher salt
13 1/2 teaspoon of ground black pepper
14 1/2 teaspoon of white sugar
15 1 1/2 teaspoons of Italian herb seasoning mix

→ Optional Toppings

16 Parmesan rind to throw into the pot while cooking (if you want)
17 Chopped fresh parsley for garnish
18 Some grated Parmesan cheese for serving

Instructions

Step 01

Warm up the olive oil in a big pan over medium-high heat. Toss in the onion and let it cook until golden and soft, about 8 minutes. Add in the diced carrots and celery with the seasonings; let it all cook for another 2 minutes. Stir in the garlic and cook for 30 seconds. Move this veggie mixture to your slow cooker.

Step 02

Pour the lentils, both tomato kinds, and broth into your slow cooker. Seal the lid, and let it cook for 3-4 hours on high or 6-8 hours on low. The lentils should end up soft but hold their shape.

Step 03

If you used a Parmesan rind, take it out now. Stir in the sugar and vinegar, and adjust the consistency by adding broth if it’s too thick.

Step 04

Dish it out into bowls and top with parsley and Parmesan if you’d like. It’s great warm, with some bread for dipping on the side.

Notes

  1. Keeps in the fridge for about 5 days and can freeze for 3 months.
  2. Can also be made on the stovetop in roughly 25 minutes.
  3. Avoid using red lentils; they’ll turn to mush in this recipe.
