Before you start

Before starting, gather all the ingredients and equipment. Rinse the dried red beans under cold water and pick out any debris. Slice the smoked sausage into rounds about 1/4-inch thick. If using lardons, they may already be in small strips; if not, chop thick-cut bacon into small pieces.

Slice the onion into thin half-moons. Measure out the ground cumin and tomato coulis. Have your slow cooker ready – a 5 to 6 quart model works well for this recipe. No pre-cooking or browning is required, so you can go straight from prep to slow cooker.

Ingredients at a glance (6)
  • 1 lb smoked sausage, sliced into rounds
  • 4 oz lardons (or thick-cut bacon, chopped)
  • 1 lb dried red beans, rinsed
  • 1 large yellow onion, sliced
  • 2 tsp ground cumin
  • 2 cups tomato coulis (or crushed tomatoes)

Instructions

Layer and Season

  1. Layer the ingredients
    Place the sliced smoked sausage and lardons in the bottom of the slow cooker. Scatter the rinsed red beans and sliced onions over the top, spreading them evenly.
    Look for The sausage and lardons form a single layer at the bottom, with beans and onions piled on top.
    Tip No need to stir at this point; the layers will meld during cooking.
  2. Add the spices and tomato
    Sprinkle the ground cumin evenly over the beans and onions. Pour the tomato coulis over everything, making sure it covers the ingredients as much as possible.
    Look for The tomato coulis creates a rich, red liquid that coats the beans and sausage.
    Tip If the coulis is thick, you can add a splash of water or broth to help it spread.

At the end of this phase, the slow cooker contains distinct layers: sausage and lardons at the bottom, then a pile of red beans and onions, with cumin sprinkled over and tomato coulis poured on top. The ingredients look vibrant and colorful, and the aroma of cumin and tomato is fresh and inviting. There is no need to stir; the layers will meld during cooking.

Slow Cook

  1. Cook low and slow
    Cover the slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the beans are tender and the sausage is cooked through. Let it rest for 3 minutes before slicing.
    Look for The aroma of cumin and tomato fills the kitchen as the beans soften.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Stir once halfway through if possible, but resist frequent opening of the lid.

As the slow cooker works, the kitchen fills with a rich, smoky, and slightly sweet aroma. The tomato coulis turns a deeper red as it melds with the rendered fat from the sausage and lardons.

The beans gradually soften and absorb the liquid, becoming plump and creamy. By the end of this phase, the mixture should be bubbling gently and the beans should be tender when tested.

Finish and Serve

  1. Finish and serve
    Once the beans are tender and the sausage is fully cooked, stir the mixture well. Serve hot, spooned into bowls with any extra cooking liquid.
    Look for The dish is glossy, thick, and steaming, with tender beans and browned sausage.
    Tip Taste and adjust seasoning with salt and pepper before serving.

The finished dish is glossy and thick, with tender beans and browned sausage pieces suspended in a rich, savory sauce. The onions have melted into the sauce, adding sweetness. The aroma is intensely comforting – smoky, tomatoey, and warmly spiced. Stir the mixture well; it should look cohesive and hearty. Serve hot, with rice or bread if desired.

Common mistakes

One common mistake is not adding enough liquid – the beans need moisture to soften. The tomato coulis provides most of the liquid, but if it seems too thick, add a cup of water or broth. Another mistake is lifting the lid too often, which releases heat and extends cooking time.

Also, be patient: dried beans take time to become tender. If using canned beans, do not cook them for the full 8 hours or they will turn to mush. Finally, don’t skip the cumin – it’s the backbone of the flavor.

How to tell it’s done

The dish is done when the red beans are tender and easily mashed with a fork, and the sausage is fully cooked (reaching an internal temperature of 145°F (63°C) for whole cuts of meat).

The sauce should be thick and glossy, clinging to the beans and sausage. If the beans are still firm, continue cooking in 30-minute increments until they are soft. Taste and adjust seasoning with salt and pepper before serving.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
