Slow Cooker Shrimp and Sausage Jambalaya

Jambalaya usually means standing at the stove, stirring a pot for the better part of an hour while the flavors build. This version lets a slow cooker do that part instead — sausage, tomatoes, peppers, and Cajun spice simmer together for hours until the base tastes like it’s been on the stove all day, with almost no attention required. Shrimp only gets added right at the very end, stirred in for the last few minutes so it turns tender and pink instead of tough and rubbery. Spooned over rice, it’s a full, genuinely spicy dinner that mostly cooks itself.

Why This Slow Cooker Shrimp and Sausage Jambalaya Works

The slow cooker builds real depth. Hours of low heat let the sausage, tomatoes, and spices meld into a base that tastes far more complex than the hands-on time suggests.
Shrimp goes in at the very end, not the start. Ten to fifteen minutes is all it needs — any longer and it turns tough.
Mostly hands-off. Outside of a few minutes of chopping, the slow cooker does the real work while you’re doing anything else.
A full meal, not just a side. Sausage, shrimp, vegetables, and rice together make this genuinely dinner, not an appetizer.

What You’ll Need

You’ll want a slow cooker (4- to 6-quart) and a separate pot for the rice, since it cooks more reliably on the stovetop than directly in the crock.

1 pound andouille sausage, sliced into rounds
1 (14.5-ounce) can diced tomatoes
1 bell pepper, diced
1 yellow onion, diced
2 celery stalks, diced
3 cloves garlic, minced
2 cups chicken broth
1 tablespoon Cajun or Creole seasoning, plus more to taste
1 bay leaf
1 pound raw shrimp, peeled and deveined
1 1/2 cups long-grain white rice, cooked separately
2 green onions, sliced, for serving
Hot sauce, for serving

Step-by-Step Instructions

Build the base. Add the sausage, tomatoes, bell pepper, onion, celery, garlic, broth, Cajun seasoning, and bay leaf to the slow cooker and stir to combine.
Cook low and slow. Cover and cook on LOW for 6 to 7 hours, or HIGH for 3 to 4 hours, until the vegetables are tender and the base smells deeply savory.
Cook the rice. About 20 minutes before serving, cook the rice separately according to the package directions.
Add the shrimp. Stir the raw shrimp into the hot slow cooker base and cook on HIGH for 10 to 15 minutes, until pink, opaque, and curled into a “C” shape. Discard the bay leaf.
Serve. Spoon the jambalaya over the rice, top with green onions, and serve with hot sauce on the side.

Pro Tips

Add the shrimp last, always. This is the one rule that makes shrimp work in a slow cooker at all — stirred in for the final stretch, not cooked alongside everything else for hours.
Cook the rice separately for the best texture. Rice cooked directly in the crock for hours tends to turn gluey; a stovetop pot timed to finish around the same time gives more reliable results.
Use shrimp that’s fully thawed, not frozen-solid. A quick rinse under cold water first means it cooks through evenly in that short window instead of staying cold in the middle.
Taste and adjust the Cajun seasoning at the end. Brands vary widely in saltiness and heat, so it’s easier to add more than to fix an oversalted pot.
Don’t skip the sear if you have extra time. Browning the sausage in a skillet before it goes into the slow cooker isn’t required, but it adds a noticeably deeper flavor.

Variations & Alternatives

Extra spicy: Add a diced jalapeño with the vegetables, or a dash of hot sauce directly into the base.
No shrimp on hand: Stir in cooked, shredded chicken instead during the last 15 minutes, just to warm through.
Brown rice swap: Use brown rice instead of white, cooked separately, since it takes longer and would turn mushy in the slow cooker regardless.
Vegetarian version: Skip the sausage and shrimp, use vegetable broth, and add a can of drained kidney beans for protein instead.

Storage & Reheating

Refrigerate the jambalaya base and rice separately in airtight containers for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of broth if it’s thickened up in the fridge. The shrimp can turn a little firmer after reheating, but the flavor holds up well. This dish doesn’t freeze especially well once the shrimp and rice are mixed in.

FAQ

Can I put raw shrimp in a slow cooker for the full cook time? No. Shrimp cooks through in minutes, so hours in a slow cooker turns it tough and rubbery, and a frozen block also spends too long at unsafe temperatures before it heats through. Add it only in the last 10 to 15 minutes.

Can I cook the rice directly in the slow cooker? You can, but it’s harder to get right — rice left in a slow cooker for hours tends to turn gummy. Cooking it separately and stirring it in gives a more reliable texture.

What can I use instead of andouille sausage? Any smoked sausage or kielbasa works, though andouille brings more heat and a more traditional Cajun flavor.

Is this jambalaya very spicy? It has a noticeable kick from the Cajun seasoning, but it’s adjustable — use less seasoning for a milder version, or add hot sauce at the table for more heat.
