Cook the pasta in a large pot of boiling water until it's almost al dente, reserving around 1 cup of pasta water before draining.
8 ounces dry rigatoni pasta
While the pasta cooks, heat the olive oil in a deep skillet set over medium-high heat. Once the skillet is hot, cook the shrimp for approximately 3 minutes, flipping once. Once done, transfer the shrimp to a plate.
1 tablespoon olive oil
Add the chicken to the same skillet. Cook it for about 5-6 minutes until it's fully cooked and golden brown. Stir occasionally during the cooking process. Afterward, place the chicken on the same plate as the shrimp.
In the same skillet, melt the butter and sauté the minced garlic for about 30 seconds. Add the diced tomatoes, heavy whipping cream, ½ cup of the reserved pasta water, and the remaining ½ tablespoon of Cajun seasoning.
2 tablespoons unsalted butter, 2 cloves garlic, ½ cup diced tomatoes, 1 cup heavy whipping cream
Allow the sauce to simmer for roughly 2-3 minutes until it thickens, then stir in the grated Parmesan cheese.
½ cup grated Parmesan cheese
Add the cooked chicken, shrimp, and pasta into the skillet, letting them warm together for 1-2 minutes. Season with additional salt and pepper according to your taste.
When serving, garnish with extra Parmesan cheese, a sprinkle of red pepper flakes, and fresh parsley.
crushed red pepper flakes, chopped fresh parsley
Notes
*Boneless chicken thighs can be used instead.**Cajun seasoning can have varying levels of spiciness depending on the brand and blend. If you're sensitive to heat, you can adjust the amount of Cajun seasoning used to suit your taste.***I like rigatoni for this recipe, but any short shape like penne or farfalle will work.Tips:
Cook the pasta just shy of al dente; it will finish cooking in the sauce, absorbing flavor and staying perfectly tender.
Don't forget to reserve some of that liquid gold cooking water from the pasta. It's the key to a silky, creamy sauce that clings to the pasta.
Pat the shrimp and chicken dry before seasoning them. This will help them brown and caramelize more easily.
If the sauce seems too thick, whisk in a little reserved pasta water gradually until you reach a creamy, silky texture.
Make-Ahead: You can prep and season the chicken and shrimp a few hours in advance, but cook them just before tossing with pasta to maintain tenderness.Storage: Store Cajun pasta in an airtight container in the refrigerator for up to 3 days. I do not recommend freezing this dish.
