Cook bacon in a large Dutch oven or heavy-bottomed pot over medium heat until crispy, about 8-10 minutes, then remove and chop into bite-sized pieces. Pour off all but 2 tablespoons of bacon fat. Add the diced onion, chopped bell peppers, and celery (the holy trinity of Cajun cooking) to the pot and sauté until softened and translucent, about 8-10 minutes. This foundation will create the deep, savory base that makes this dish authentic. Add the minced garlic and cook for another 2-3 minutes until fragrant.
Add the cubed pork to the pot and cook for 10-12 minutes, stirring occasionally, until it begins to brown at the edges. Then add the sliced smoked sausage and cook for another 10-12 minutes, allowing both proteins to develop color and deepen the overall flavor. I like to let the sausage caramelize slightly because it adds a wonderful richness to the whole dish. Add the chicken thighs and chicken breast chunks and cook for 15-20 minutes until the chicken is mostly cooked through and lightly browned.
Add the diced tomatoes and chilies, fresh thyme sprigs, Creole seasoning, bay leaf, water, and chicken broth to the pot and stir well to combine. Pour in the browning sauce for that rich, dark color that makes authentic pastalaya so visually appealing. Add the cream of chicken soup and cream of mushroom soup, stirring until smooth. Bring the mixture to a gentle simmer and cook uncovered for 20 minutes, allowing the flavors to meld and the sauce to thicken slightly. This simmering time is crucial for developing that deep Cajun flavor.
While the sauce simmers in Step 3, preheat your oven to 300°F. When the sauce is ready, add the dry pasta directly to the pot and stir well to break up any clumps and ensure every piece is submerged in liquid. Bring the mixture to a boil over medium-high heat, stirring occasionally to prevent sticking. Once boiling, remove the pot from the heat.
Carefully transfer the pot to the preheated 300°F oven and cover tightly with a lid or aluminum foil. Bake for 1 hour, stirring once halfway through cooking if needed to ensure even cooking. The low, gentle heat allows the pasta to absorb all the flavors while the sauce becomes creamy and cohesive. Remove from the oven and let the dish rest uncovered for 10 minutes—this resting time helps the flavors settle and the pasta finish cooking perfectly in the residual heat.
Stir in the fresh chopped green onions, which add a bright, fresh note that balances the rich, smoky flavors. Remove the bay leaf and thyme sprigs. Taste and adjust seasoning if needed. Divide among bowls and serve immediately while hot.
