JUMP TO RECIPE

This creamy Southwest Chicken Linguine pasta dish is loaded with grilled chicken, mushrooms, and green onions with a southwestern spiciness from the addition of Rotel tomatoes. This chicken pasta recipe has become a family favorite that I can get on the table in 30 minutes!

Our family eats pasta at least once a week. It’s one of those dinners that my entire family enjoys. That’s why when I find a winner to add to the rotation, I have to share it with you! This linguine, with its Southwestern flavors, had my heart instantly. Rotel tomatoes, mushrooms, grilled chicken, onions … all tossed together in this most amazing creamy sauce that’s just slightly spiced. Swoon!

My foodie pal, Brandi from Aunt Bee’s Recipes, posted this recipe for a recipe share we were both involved in for Mother’s Day a few years back. I was intrigued by the ingredients. As I said, I love pasta, but I’m not always a big fan of heavy cream sauces like Alfredo. She assured me that I would love this recipe, and she was right! It’s not a thick heavy cream sauce, like a traditional Alfredo sauce. Am I the only person on earth who isn’t a fan of Alfredo? Quite possibly. Her recipe is named Southwestern Chicken Linguine Alfredo, but I left the “Alfredo” part off in my title.

I am so happy to have found this recipe, and so is my family. For a meatless option, it’s perfectly tasty to leave the chicken out, so keep that in mind, too. We like to have it that way during Lent. Of course, if you LOVE chicken, you will want to take a peek at this 20+ Family Favorite Chicken Recipes round-up that I have available. It’s literally a one-stop recipe stop for all sorts of chicken recipes and ways to use leftover chicken.

Ingredients in Southwest Chicken Linguine Recipe

You will find all of the exact measurements and instructions at the bottom of this post in the printable recipe card.

Skinless chicken breasts – grilled and sliced. Or substitute 1.5 pounds of frozen grilled chicken fajita meat or any leftover chicken. Brandi has a special grilled chicken marinade she loves to use on her chicken but when I’m pressed for time I cheat and use one of my favorite “go-to” freezer items.

Butter – I used salted butter but unsalted works too. Just adjust your salt accordingly.
Mushrooms – Freshly sliced mushrooms add a meaty texture to this dish. I used white mushrooms but baby bella would be a great alternative.
Onion – I used a sweet onion, diced but you can also use a red onion.
Garlic – Fresh minced garlic is best but jarred will also work.
Diced tomatoes – I used one can of diced tomatoes, undrained.
Rotel diced tomatoes – I used one can of mild Rotel tomatoes with green chilies, undrained. You can determine the heat of the sauce by the kind of Rotel tomatoes you choose.
Salt and pepper – A touch of salt and pepper to enhance the taste.

Heavy cream – Heavy cream adds richness to the sauce.
Parmesan cheese – I used Parmesan cheese in the dish and for serving.

Linguine noodles – Cook the linguine al dente. You can also use another long flat pasta like fettuccine.

Green onions– Green onions add a nice color and look great as a garnish on this southwest chicken alfredo.

How To Make Southwest Chicken Linguine Pasta

First: In a large skillet, melt butter over medium heat.

Second: Add the mushrooms and onions and saute until softened. About 10 minutes. Add the minced garlic and continue cooking for 1 minute stirring constantly.

Fourth: Reduce heat to medium, add the cream and Parmesan cheese, and continue cooking until sauce thickens slightly, about 10 more minutes. Stirring occasionally.

Toss cooked noodles with prepared sauce. Top with sliced grilled chicken and lots of green onions.
