Southwest Chicken Pasta is a comforting weeknight dinner that combines tender chicken, penne pasta, black beans, corn, tomatoes with green chilies, and a rich homemade Alfredo sauce. The combination creates a creamy pasta dish with Southwest-inspired flavor, while taco seasoning, onion, and garlic add savory depth.
I especially like this chicken pasta recipe because it brings together simple ingredients in a way that feels satisfying without being complicated. Many of the ingredients are pantry or refrigerator staples, and the cooking process is straightforward enough for home cooks of different skill levels.
Southwest Chicken Alfredo Penne Pasta–The Short Answer
With about 15 minutes of preparation and 25 minutes of cooking time, this Southwest Chicken Pasta is a practical option for busy evenings, family dinners, and regular weeknight meal rotations.
What makes this Southwest Chicken Pasta different is how the Southwest ingredients complement the creamy Alfredo sauce rather than replacing it. Seasoned chicken, corn, black beans, and diced tomatoes with green chilies are combined with penne pasta and homemade Alfredo sauce to create a dish with contrasting flavors, textures, and colors.
The vegetables and beans add heartiness, while the Alfredo sauce keeps the dish creamy and familiar. A layer of melted cheese on top provides a satisfying finish and brings the ingredients together into a comforting skillet meal that works well for both kids and adults.
The Alfredo foundation gives this recipe a familiar comfort-food quality. Traditional Alfredo is often paired with fettuccine, but the creamy sauce works especially well with penne because the pasta shape holds the sauce while also pairing with chunky chicken, beans, corn, and tomatoes.
This balance between creamy Alfredo comfort and bold Southwest flavor is what makes Southwest Chicken Alfredo a unique and satisfying pasta dinner.
Why You’ll Love This Southwest Chicken Pasta
When I want a simple dinner for a busy weeknight, this chicken Alfredo penne pasta is a practical choice. The recipe combines tender chicken, penne pasta, creamy sauce, and flavorful vegetables while keeping the cooking process organized and manageable.
The pasta is cooked separately before everything comes together in the skillet, which helps maintain the right texture. The straightforward steps make the recipe approachable while still creating a meal that feels complete and satisfying.
The Alfredo sauce provides the classic creamy foundation using heavy cream, cream cheese, and Parmesan. Taco seasoning adds the main Southwest flavor, while corn, black beans, and tomatoes with green chilies create a combination of sweetness, texture, acidity, and color.
The result is a rich and comforting chicken pasta that feels different from traditional Alfredo without losing the familiar creamy character people enjoy. It is a practical dinner choice when you want something hearty, flavorful, and easy to prepare.
Ingredients Needed
This Southwest Chicken Pasta uses simple ingredients that work together to create a creamy Alfredo base with Southwest-inspired flavor. Each component has an important role, from building the pasta texture to adding richness, color, and savory depth.
For the pasta, use:
- 12 oz (340 g) dry penne pasta
- ½ cup (120 ml) reserved pasta water
Cook the penne according to the package directions until al dente, preferably about 1 minute less than the maximum recommended cooking time. Reserving pasta water helps adjust the sauce consistency later, while keeping the pasta slightly firm allows it to finish cooking when combined with the Alfredo sauce.
For the chicken, use:
- 1 lb (450 g) boneless, skinless chicken breasts, cut into ¾–1-inch bite-size pieces
- 2 tablespoons taco seasoning (approximately 14–16 g)
- 1 tablespoon olive oil
The chicken is seasoned with taco seasoning before cooking, which gives the dish its main Southwest flavor. Cutting the chicken into evenly sized pieces helps it cook consistently and remain tender throughout the pasta.
For the Southwest base, use:
- 1 tablespoon olive oil
- 1 small yellow onion (approximately 100 g), finely diced
- 3 garlic cloves (approximately 9 g), minced
- 1 cup (165 g) canned corn, drained and rinsed
- 1 cup (170 g) canned black beans, drained and rinsed
- 1 can (10 oz / 283 g) diced tomatoes with green chilies, drained
The onion and garlic create the savory foundation of the dish, while corn, black beans, and tomatoes with green chilies add sweetness, texture, acidity, and the recognizable Southwest character.
For the Alfredo sauce, use:
- 2 tablespoons unsalted butter (28 g)
- 1¼ cups (300 ml) heavy cream
- ¾ cup (180 ml) low-sodium chicken broth
- 3 oz (85 g) softened cream cheese
- ½ cup (60 g) freshly grated Parmesan cheese
- ½ teaspoon fresh thyme leaves (optional)
- ¼ teaspoon freshly ground black pepper
The Alfredo sauce combines heavy cream, cream cheese, and Parmesan to create a smooth, rich texture. Chicken broth adds savory depth while helping balance the richness of the dairy ingredients. Keeping the heat controlled while combining these ingredients helps the sauce remain creamy and smooth.
For the finishing ingredients, use:
- ½ cup (50 g) shredded Monterey Jack or cheddar cheese
- 2–3 tablespoons chopped fresh cilantro (approximately 6–9 g)
The finishing cheese creates a melted layer over the pasta, while fresh cilantro adds a bright contrast to the rich Alfredo sauce. For the best texture and flavor, freshly grate the Parmesan and shred the finishing cheese before adding them to the skillet.
How to Make Southwest Chicken Pasta
Start by cooking the penne pasta. Bring a large pot of water to a full boil, then add 2 teaspoons kosher salt and 12 oz (340 g) penne pasta. Cook according to the package directions until al dente, preferably about 1 minute less than the maximum recommended time.
Before draining the pasta, reserve ½ cup (120 ml) pasta water. Drain the pasta in a colander without rinsing it. Keeping the pasta slightly firm helps it maintain its texture when it is combined with the creamy Alfredo sauce later.
Prepare the chicken by cutting 1 lb (450 g) boneless, skinless chicken breasts into evenly sized ¾–1-inch pieces. Add 2 tablespoons taco seasoning and toss until the chicken is evenly coated.
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the seasoned chicken in a single layer and cook for about 2–3 minutes per side, continuing until the thickest pieces reach 165°F (74°C).
Transfer the cooked chicken to a clean plate instead of leaving it in the skillet. This prevents the chicken from overcooking while the Southwest base and Alfredo sauce are prepared.
Using the same skillet, add the remaining 1 tablespoon olive oil. Cook the finely diced onion over medium heat for about 3–4 minutes until softened. Add the minced garlic and cook for 30–60 seconds until fragrant, being careful not to let it burn.
Add the drained corn, black beans, and diced tomatoes with green chilies to the skillet. Cook for 1–2 minutes, allowing the vegetables to warm through while keeping some of their texture.
Reduce the heat to medium-low and add the butter, heavy cream, chicken broth, black pepper, and optional fresh thyme. Whisk in the softened cream cheese until smooth, then gradually add the freshly grated Parmesan cheese.
Stir gently until the cheese melts and the sauce becomes creamy. Keep the heat controlled and avoid a hard boil because excessive heat can affect the texture of the cream and cheese sauce.
Add the drained penne pasta to the skillet and gently toss until it is fully coated with the Alfredo sauce. Return the cooked chicken and any accumulated juices to the skillet, then heat everything together for about 1–2 minutes.
If the sauce is too thick, add the reserved pasta water 1 tablespoon at a time. Usually 2–4 tablespoons is enough, but the exact amount depends on how much moisture the pasta absorbs.
Turn the heat to low or remove the skillet from the heat. Sprinkle ½ cup (50 g) shredded Monterey Jack or cheddar cheese over the pasta, then cover for 1–2 minutes to allow the cheese to melt.
Avoid aggressively stirring after adding the finishing cheese because this helps maintain the melted cheese layer. Garnish with 2–3 tablespoons chopped fresh cilantro and serve hot.
If desired, spinach can be folded in during the final pasta stage, and garlic bread or another favorite side dish can be served alongside.
Make Ahead and Leftovers
For the best texture, this pasta is best assembled and served immediately because penne continues absorbing the creamy Alfredo sauce as it sits.
If you want to prepare components ahead of time, the chicken, chopped vegetables, and grated cheese can be prepared separately and refrigerated until needed. The pasta and Alfredo sauce are best prepared closer to serving time.
For leftovers, cool the Southwest Chicken Pasta promptly and transfer it to an airtight container. Store it in the refrigerator for 3–4 days.
When reheating, use the microwave or stovetop and add a small splash of water, milk, chicken stock, or low-sodium chicken broth if the pasta needs additional moisture.
Reheat gently until hot, stirring occasionally so the sauce becomes evenly distributed again. Gentle reheating helps maintain a smoother texture because the pasta continues absorbing sauce while stored.
Tips and Notes
If using already cooked chicken, shredded chicken, leftover chicken, or rotisserie chicken, only a few changes are needed. Skip the olive oil used for cooking raw chicken and use the oil for the onion instead.
Cook the onion until softened, then add the cooked chicken with the fresh garlic and continue with the Southwest vegetables and Alfredo sauce. This keeps the cooked chicken from being heated longer than necessary.
Heavy cream is important for achieving the intended Alfredo sauce consistency. Lower-fat milk can make the sauce thinner and less able to properly coat the pasta.
Always reserve some pasta water after cooking the penne. It can help adjust the sauce thickness if needed. If the sauce is too thin, allow it to simmer gently for a little longer, but avoid a hard boil because the sauce contains cream and cheese.
For extra heat, add chili powder, red cayenne pepper, or another spicy seasoning with the taco seasoning. Green chilies can also increase the spice level.
Pepper Jack cheese can replace Monterey Jack or cheddar for a stronger Southwest flavor. Chopped jalapeños or fresh jalapeños also make a good garnish.
Drain and rinse canned black beans and corn before using them, especially because canned ingredients can contain extra salt. Frozen or fresh corn can also be used.
Red kidney beans can replace black beans if desired. For less heat, use plain petite diced tomatoes instead of tomatoes with green chilies. For additional Southwest flavor, diced tomatoes with green chilies or Rotel-style tomatoes can be used.
Freshly grated Parmesan from a block melts more smoothly into the sauce than some pre-grated varieties. Some pre-grated products contain anti-caking agents that may affect the final texture.

FAQ
Can I Use Already Cooked Shredded Chicken or a Rotisserie Chicken?
Yes, you can use already cooked chicken, shredded chicken, or rotisserie chicken to save preparation time.
The main change is to skip cooking the raw chicken pieces in olive oil. Instead, use the oil to sauté the onion and garlic until softened, then add the cooked chicken briefly with the Southwest vegetables before continuing with the Alfredo sauce.
This approach helps prevent the chicken from becoming overcooked while still allowing it to warm through and absorb the flavors of the dish.
Can I Make It Spicy?
Yes, the spice level can be adjusted easily based on your preference.
For more heat, add chili powder or red cayenne pepper along with the taco seasoning. Green chilies or diced green chilies can also increase the Southwest flavor and spice level.
For a different cheese option, replace Monterey Jack or cheddar with Pepper Jack cheese. Fresh jalapeños can also be added as a garnish or mixed with the corn and black beans for additional heat throughout the dish.
Can I Make This Pasta Ahead of Time?
This chicken Alfredo penne is best served immediately while the sauce is smooth and creamy, but some components can be prepared ahead when needed.
The chicken, vegetables, and cheese can be prepared separately and refrigerated. For the best final texture, cook the pasta and prepare the Alfredo sauce closer to serving time.
Leftovers can be stored in the refrigerator for 3–4 days. When reheating, warm the pasta gently on the stovetop or in the microwave and add a small splash of liquid if the sauce has thickened.
Since the pasta continues absorbing the sauce as it sits, gentle reheating helps bring back a smoother consistency.
Can You Cook Penne With Chicken Broth?
For this recipe, penne is cooked in salted water rather than chicken broth.
The chicken broth is added later to the Alfredo sauce, where it provides savory flavor and combines with the cream, cheese, and seasonings.
After cooking the pasta, reserved pasta water can be added to the sauce if needed. This helps loosen the sauce and brings the pasta and other ingredients together without making the finished dish too thick.
What Else Can I Add to This Southwest Penne Pasta?
You can make small additions while keeping the main Southwest and Alfredo flavors intact.
For more spice, add jalapeños, green chilies, or another preferred chili. For extra vegetables, spinach can be folded in during the final pasta stage, or broccoli can be added so it has time to soften.
Pepper Jack cheese can replace the finishing cheese for a stronger Southwest flavor. These additions allow flexibility while maintaining the creamy pasta base.
What Pasta Should I Use for This Southwest Chicken Alfredo?
Penne works especially well because its shape holds the creamy Alfredo sauce while pairing nicely with chunky chicken, beans, corn, and tomatoes.
The hollow shape helps create a balanced bite with pasta and Southwest ingredients together in each serving.
Other short pasta shapes such as rotini, macaroni, or farfalle can also work. Fettuccine and other long noodles are less practical with the chunky ingredients.
Whole wheat pasta can be used, although cooking time may vary slightly. Gluten-free pasta can also be used by following the package cooking instructions.
What Is the Alfredo Sauce in This Southwest Pasta?
The Alfredo sauce is a cream-based sauce that gives this pasta its smooth texture and rich flavor.
In this recipe, it is made with butter, heavy cream, chicken broth, cream cheese, and Parmesan cheese. These ingredients are combined until smooth and creamy before being mixed with the pasta and Southwest ingredients.
The tomatoes and green chilies are added as part of the Southwest base before the Alfredo ingredients are incorporated. This allows them to add acidity, brightness, color, and flavor while keeping the Alfredo foundation rich and creamy.
