Start by bringing a large pot of salted water to a boil, then add your chosen pasta—linguine or fettuccine—and cook according to package instructions until al dente, which typically takes around 8-10 minutes.
While the pasta cooks, take your shrimp and chicken pieces and toss them in half of the Cajun seasoning in a bowl for added flavor before cooking them separately in a hot skillet with olive oil.
Once your proteins are cooked, use the same skillet to sauté your bell peppers, onion, and garlic until they’re soft and fragrant—this step builds layers of flavor in your dish.
In the same skillet, melt butter over medium heat before whisking in flour to form a roux; gradually add chicken broth followed by heavy cream while whisking until smooth—this will form the luxurious sauce that coats everything deliciously. Continue following through with returning your proteins and veggies into this creamy mixture before combining it all with your drained pasta for an irresistible feast!
