5 Gallon Jambalaya Pot Recipe: Big Batch Cajun Feast for a Crowd

Feeding a crowd calls for bold flavors and generous portions, and this Cajun classic delivers both in spades. I’ve scaled every ingredient precisely for a 5-gallon pot, ensuring each bite carries the depth of traditional jambalaya without compromise.

The foundation is simple: the holy trinity of onions, bell peppers, and celery, slow-cooked with andouille sausage, chicken, and shrimp. A carefully balanced blend of Cajun spices builds layers of flavor that deepen as the dish simmers.

This method guarantees tender meat, plump shrimp, and rice that absorbs every drop of the rich, smoky broth. The result is a hearty, aromatic feast that stays true to Louisiana roots while feeding dozens with ease.

Perfect for large gatherings, fundraisers, or family reunions where a single pot can serve everyone. Here’s how to make it right.

Ingredients for 5 Gallon Jambalaya Pot

Bold Cajun flavors scaled for a crowd—every bite packed with the trinity, meats, and spices.

Quality matters at this scale. Andouille sausage should come from a trusted butcher or Cajun specialty grocers like Rouses Markets if you’re in the South. For the chicken, thighs over breasts—they stay juicy during the long simmer. Shrimp should be 16-20 count for ideal texture. The holy trinity needs to be fresh; wilted veggies won’t build the flavor base right. Stock up on Tony Chachere’s Cajun seasoning if going store-bought.

Out of andouille? Kielbasa works in a pinch but lacks the smoky punch. No fresh shrimp? Frozen and thawed is acceptable (pat dry first). For the stock, homemade is ideal but Swanson’s low-sodium does the job. Missing a trinity veggie? Double up on the others—just keep the total volume similar. Smoked paprika can’t be skipped, but regular paprika plus a dash of liquid smoke gets you 80% there.

This makes enough for 50 servings, so storage is key. Leftovers keep 4-5 days refrigerated in airtight containers, or freeze portions for 3 months. Reheat gently on the stove with a splash of water or stock. The flavors actually deepen overnight, making it perfect for meal prep or next-day gatherings.

Step-by-Step Instructions for 5 Gallon Jambalaya

This large-batch method ensures even cooking and maximum flavor development for your crowd.

Step 1: Sear the Meats and Build the Flavor Base

Heat the 1 cup Vegetable Oil in a 5-gallon pot over medium-high heat until shimmering. Working in batches to avoid crowding, add the 8 lb Boneless Skinless Chicken Thighs (cut into 1-inch chunks) and sear until deep golden brown on all sides, about 8-10 minutes per batch.

Transfer the chicken to a large bowl and repeat with the 5 lb Andouille Sausage (sliced into half-moons), cooking until caramelized. This browning creates the fond that will deepen your jambalaya’s flavor. Remove the sausage and set aside with the chicken.

Step 2: Sauté the Holy Trinity and Aromatics

In the same pot, add the 8 whole Yellow Onions (medium diced), 6 whole Green Bell Peppers (medium diced), and 12 whole Celery Stalks (finely diced). Cook over medium heat for 10-12 minutes, stirring frequently, until the vegetables soften and begin to turn translucent.

Add the 16 cloves Garlic Cloves (minced) and cook for 1-2 minutes until fragrant. Stir in the 1 can Tomato Paste and cook for 3-4 minutes, allowing it to darken slightly and develop its sweetness. This step is crucial for building the deep, complex base of your jambalaya.

Step 3: Incorporate Spices and Liquids

Sprinkle the 0.5 cup Cajun Seasoning Blend, 2 tbsp Dried Thyme (crushed between your fingers), and 2 tbsp Smoked Paprika over the vegetables. Stir well to coat everything evenly and cook for 1-2 minutes to toast the spices and release their oils.

Pour in the 128 cup Chicken Stock and add the 8 whole Bay Leaves. Stir to deglaze the pot, scraping up all the browned bits from the bottom. Bring the mixture to a rolling boil, then reduce the heat to medium-low to maintain a gentle simmer.

Step 4: Add Rice and Meats for Final Cook

Return the seared Boneless Skinless Chicken Thighs and Andouille Sausage to the pot. Stir in the 10 lb Long-Grain White Rice (rinsed until water runs clear) and ensure it is fully submerged in the liquid. This even distribution prevents clumping and ensures every grain cooks properly.

Cover the pot and cook for 25-30 minutes, stirring every 10 minutes to prevent sticking. The rice is done when it is tender and the liquid has been mostly absorbed. Taste and adjust seasoning if needed, but remember the flavors will continue to develop.

Step 5: Finish with Shrimp and Rest

Stir in the 5 lb Large Shrimp (peeled and deveined) and cook for an additional 5-7 minutes until the shrimp turn opaque and pink. Remove from heat and discard the Bay Leaves before serving.

Let the jambalaya rest, covered, for 10-15 minutes. This allows the rice to finish steaming and the flavors to meld together. Serve hot, ensuring each portion has a good mix of rice, vegetables, chicken, sausage, and shrimp for a true taste of Cajun tradition.

Flavor Customization for This Dish

Spice Level Adjustments

For milder heat, reduce the Cajun seasoning to 1/3 cup and skip the smoked paprika. I’ve found this makes it kid-friendly while keeping the essence. For extra kick, add 1 tbsp cayenne pepper with the other spices. 🌶️

Seafood Variations

Swap shrimp for 5 lb crawfish tails for an authentic Louisiana twist. Or use a mix of 2 lb shrimp and 3 lb mussels for a briny depth. The cooking time remains the same—just ensure seafood is fresh.

Meat Swaps

Replace chicken with 8 lb pork shoulder for richer flavor, or use 4 lb chicken and 4 lb smoked sausage for variety. For game day, try 3 lb chicken, 2 lb sausage, and 3 lb smoked turkey wings. 💡

Vegetable Additions

Add 4 diced tomatoes with the holy trinity for brightness. For texture, stir in 2 lb okra (sliced) when adding the rice. Mushroom lovers can include 3 lb sliced creminis for earthy depth.

Rice Alternatives

Swap white rice for 10 lb brown rice, but increase stock to 144 cups and cook for 45-50 minutes. For a low-carb option, use 10 lb riced cauliflower and reduce stock to 96 cups.

Herb Boosts

Enhance freshness with 1 cup chopped parsley stirred in at the end. Or add 1/4 cup chopped green onions as garnish. For complexity, include 2 tbsp file powder during the final 5 minutes of cooking. ✨
