Before you start

Before beginning, ensure your slow cooker insert is clean and dry. Prepare the vegetables by dicing the red and green bell peppers and the onion into uniform, bite-sized pieces to ensure even cooking.

Gather all your dry and liquid ingredients and measure them out accurately. Having everything ready to go makes the assembly phase quick and efficient, allowing you to get the slow cooker started in just a few minutes of active preparation time.

Ingredients at a glance (6)
  • 2 cups dried brown lentils
  • 2 cups diced red and green bell peppers
  • 1 cup diced onion
  • 2 tbsp chili seasoning
  • 28 oz crushed tomatoes
  • 2 cups vegetable broth

Instructions

Layering the Ingredients

  1. Prepare the Base
    Add the dried brown lentils to the bottom of the slow cooker insert. Ensure they are evenly distributed to allow for uniform cooking throughout the process.
    Look for The lentils should cover the bottom of the slow cooker insert completely without being piled too high in the center.
    Tip Rinse the lentils under cold running water in a fine-mesh sieve before adding them to the slow cooker to remove any dust or debris.

The base of the slow cooker should be covered in a uniform layer of dried lentils, followed by a scattered layer of diced bell peppers and onions. The seasonings should be distributed evenly over the top, creating a professional-looking foundation for the liquid.

Ensure the ingredients are not packed too tightly, as this allows for better heat circulation and consistent cooking throughout the entire volume of the dish.

Adding the Liquids

  1. Add Vegetables and Seasoning
    Scatter the diced red and green bell peppers and the diced onion over the lentils. Sprinkle the chili seasoning evenly across the vegetables to ensure consistent flavor distribution.
    Look for The vegetables should form a layer on top of the lentils, providing structure and aromatics that will meld during the slow cooking process.
    Tip Use a mix of different colored bell peppers to add visual appeal and a slightly varied sweetness to the final dish.

Once the tomatoes and broth are added, the liquid should just cover the lentils and vegetables. If the ingredients are mostly submerged, the moisture levels are correct. Check that no large clumps of seasoning remain on the surface; if they do, gently nudge them into the liquid with a spoon. The slow cooker insert should be clean around the rim to prevent any burnt spots from forming during the long cook time.

Slow Cooking to Tenderness

  1. Combine Liquids and Cook
    Pour the crushed tomatoes and vegetable broth over the ingredients in the slow cooker. Cover with the lid and cook on low for 6 to 8 hours until the lentils are tender.
    Look for The chili is done when the lentils are soft and have absorbed the liquid, and the vegetables are tender to the bite.
    Tip If the chili appears too thick after cooking, stir in a splash of water or additional broth until the desired consistency is reached.

At the end of the cooking time, the chili should have a rich, deep red-brown color. The aroma should be savory and inviting, with the scent of the chili spices prominent. Stir the mixture gently; the lentils should be perfectly tender and the liquid thickened into a hearty consistency. If the chili is too thick, add a small amount of water or broth to reach your preferred texture before serving.

Common mistakes

A common mistake is failing to rinse the lentils, which can introduce grit into the final dish. Another error is not ensuring the lid of the slow cooker is completely sealed, which can cause the liquid to evaporate too quickly and lead to a dry or scorched chili.

Avoid over-stirring during the cooking process, as it is unnecessary and can disrupt the temperature stability of the slow cooker, potentially extending the total cooking time significantly.

How to tell it’s done

The lentil chili is done when the brown lentils are completely tender and soft. They should yield easily to the pressure of a spoon without feeling mushy or gritty.

The peppers and onions should be soft, and the overall consistency of the chili should be thick and cohesive, with the liquid reduced into a rich sauce that coats the lentils. There is no protein to test, so rely on the texture of the lentils as the primary indicator for readiness.
