In a mixing bowl, toss the chicken pieces with 2 tablespoons Cajun seasoning until every piece is fully coated. This initial seasoning ensures the chicken absorbs maximum flavor. Set aside while you prepare other components.

Bring a large pot of salted water to a rolling boil and add a drizzle of olive oil to prevent sticking. Add the linguine and cook for approximately 7 minutes or according to package directions for al dente texture. Drain thoroughly in a colander, then toss with a small amount of olive oil to keep strands separated. Set aside.

Heat your large skillet or wok over medium-high heat with a generous drizzle of olive oil. Once the oil shimmers, add the seasoned chicken pieces in a single layer. Cook until halfway done, about 4–5 minutes, allowing a light sear to develop. Season with about ¼ teaspoon black pepper for additional depth.

Add the sliced onions directly to the chicken in the skillet. Stir and cook until the onions begin to soften and turn translucent, about 2–3 minutes. Add the sliced bell peppers and minced garlic, drizzling more olive oil if the pan looks dry. Stir everything well—the vegetables will release moisture that helps create the base of your sauce.

Add the peeled and deveined shrimp to the skillet. Season with a pinch of salt and a bit more black pepper. Cook until the shrimp turn halfway pink, approximately 2–3 minutes. Stir in the diced tomatoes, which add vibrant color, acidity, and fresh flavor to this copycat Cheesecake Factory Cajun jambalaya pasta.

Pour in 1½ cups of seafood broth, which creates that signature light yet flavorful coating. Add 2 more teaspoons of Cajun seasoning to intensify the spice profile. Bring the mixture to a boil, then reduce to a simmer. Continue cooking until both the chicken and shrimp are fully cooked through, about 5–7 minutes. The broth will reduce slightly, concentrating the flavors.

Add the cooked linguine directly to the skillet with the protein and vegetables. Using tongs or two wooden spoons, toss everything together thoroughly. This ensures the pasta absorbs the seasoned broth and all ingredients are evenly distributed throughout the dish.

Plate the Cheesecake Factory Cajun jambalaya pasta, making sure each serving has a generous portion of chicken, shrimp, and colorful vegetables. Garnish with chopped green onions or fresh parsley if desired. Serve immediately while hot to enjoy the full impact of those bold Cajun flavors.
