How Recipesdarleen publishes recipes

Step one is the one that matters most: soaked red beans are covered with fresh water, brought to a rolling boil for ten minutes, then drained and rinsed before they go anywhere near the crock. The recipe puts it first and states it plainly.

After that it is a conventional red beans build — andouille browned for its fond, the trinity softened in the same pan, and everything left alone for seven to eight hours until the beans are tender and creamy.

Why This Recipe Works

  • Browning the andouille first leaves fond in the skillet that the trinity then picks up, so the smokiness is in the pot rather than only on the sausage.
  • The Cajun seasoning is split: a tablespoon at the start to cook in, and a tablespoon at the end, where it stays sharp.
  • Mashing 1 to 2 cups of the beans against the side of the cooker thickens the pot with the beans themselves rather than with flour or starch.
  • Cooking the rice separately keeps it fluffy — it never absorbs the bean liquid, which is what makes a one-pot version turn to porridge.

Ingredient Notes

Dried small red beans or red kidney beans
A pound, rinsed and sorted, and subject to step 1's soak-and-boil. Canned beans are allowed but go in for the last 2 hours only.
Smoked ham hock or turkey wings
Optional, and it adds smoky depth. The vegan variation replaces it with liquid smoke.
Cajun seasoning, divided
Two tablespoons total, preferably salt-free so the separate teaspoon of salt stays adjustable.

How to Make It

  1. Prepare the dried beans

    Soak overnight, or quick-soak. Drain, cover with fresh water, bring to a rolling boil for 10 minutes, then drain and rinse before adding them to the slow cooker. Do not shortcut this step.

  2. Brown the andouille

    Heat the olive oil in a skillet over medium-high and sear the sausage half-moons until browned at the edges, 3 to 4 minutes. Move them to the cooker.

  3. Sauté the trinity

    In the same pan, cook the onion, bell pepper and celery with a pinch of salt 3 to 4 minutes, then the garlic for 30 seconds. Transfer to the cooker.

  4. Load the cooker

    Add the beans, the ham hock if using, a tablespoon of Cajun seasoning, smoked paprika, thyme, bay leaves, cayenne, black pepper, Worcestershire, hot sauce and the broth. Stir.

  5. Cook long

    Cover and cook on Low 7 to 8 hours or High 4 to 5, until the beans are tender and creamy. Canned beans instead go in for only the last 2 hours on Low.

  6. Thicken with the beans

    Take out the ham hock and bay leaves. Mash 1 to 2 cups of beans against the side of the cooker, stir in the second tablespoon of Cajun seasoning and salt to taste, then the parsley and green onions.

  7. Cook the rice

    Prepare the rice according to its package and fluff it. Two cups uncooked gives about six cups cooked.

  8. Serve

    Spoon the beans over the rice, with lemon, extra hot sauce and more green onions if you like.

The Step Before the Slow Cooker

This recipe puts one instruction ahead of everything else, and it is worth reading before you start rather than at the point you need it.

  1. SoakSoak the dried red beans overnight in plenty of water, or use a quick-soak. Then drain them.
  2. Fresh waterCover the drained beans with fresh water rather than cooking them in the soaking liquid.

Check before you continue

A full rolling boil, held for 10 minutes — A pot on the stove, not the slow cooker

Bring the beans to a rolling boil and hold it for the full ten minutes, then drain and rinse them again. The recipe states this as its first step for dried beans rather than as an optional refinement, and it is reproduced here as written.

  1. Into the cookerOnly now do the beans join the browned sausage, the trinity, the seasonings and the broth.
  2. Or skip the beans entirelyThe recipe's own alternative is canned beans, which need none of this and go in for the last 2 hours on Low.

Success Tips

  • The ten-minute rolling boil in step 1 is not a texture step and not optional. Do it before the beans go into the cooker.
  • Use the second tablespoon of Cajun seasoning at the end as written — spices added at hour one taste flat by hour eight.
  • Adjust salt only after the ham hock comes out. Smoked meats give up a lot of it over seven hours.

Serving Ideas

Eight servings, beans over rice, with lemon wedges, extra hot sauce and green onions.

Frequently Asked Questions

Why boil the beans before slow cooking?

It is the recipe's own first step for dried red beans: after soaking, cover with fresh water, boil hard for 10 minutes, then drain and rinse. Follow it as written.

Can I use canned beans?

Yes. The recipe adds them for the last 2 hours on Low rather than at the start.

Is there a vegan version?

The recipe gives one: omit the meats, use vegetable broth, and add liquid smoke to taste.
