Southwest chicken Alfredo combines penne and seasoned chicken strips with a creamy cheddar sauce, diced tomatoes, and warm spices. Chili powder, cumin, paprika, and a little cayenne give the sauce its Southwest flavor, while honey adds a light sweetness to the chicken. This version uses heavy cream and cheddar rather than a Parmesan sauce, making it a rich pasta dinner with a different flavor from classic Alfredo.
Southwest chicken Alfredo works best in stages: cook the pasta, brown the chicken, soften the vegetables, and bring the sauce together over gentle heat. Removing the cooked chicken while you build the sauce protects it from prolonged simmering. Measure the spices and grate the cheddar first so the final sauce and pasta toss can move smoothly.

Why This Recipe Works
Dividing the seasoning blend flavors both the meat and sauce in southwest chicken Alfredo. Browning the chicken first gives the meat a savory surface, then removing it leaves room to soften the onion. Cheddar melts into the cream near the finish, coating the pasta without prolonged boiling.
The sauce for the pasta uses heavy cream and cheddar for its creamy coating, while the tomatoes add moisture and acidity. Add the cheese with the heat lowered so it can melt without a strong boil. The cooked pasta goes in at the end, making it easier to judge how much sauce coats each portion.
Ingredients for Southwest Chicken Alfredo
Use 1/2 pound dry penne and 1 pound chicken breast cut into strips. The sauce contains a 15-ounce can diced tomatoes, 1 cup heavy cream, and 1 1/2 cups shredded cheddar, plus onion, garlic, olive oil, and butter. Mix all the measured seasonings before dividing them: half flavors the honey-coated chicken and half goes into the tomatoes. Cilantro finishes the dish.
- 1/2 lb penne pasta
- 1 lb boneless, skinless chicken breasts, cut into 1-inch strips
- 1 15 oz can diced tomatoes
- 1 cup heavy cream
- 1 1/2 cups cheddar cheese, shredded
- 1 cup onion, chopped
- 4 cloves garlic, minced
- 1 tbsp honey
- 1 tbsp olive oil
- 1 tbsp butter
- 2 tbsp cilantro, chopped
- 1 1/2 tsp chili powder
- 1/2 tsp cumin
- 1/2 tsp oregano
- 1 tsp paprika
- 1/4 tsp black pepper
- 1/2 tsp salt
- 1/8 tsp cayenne
How to Make Southwest Chicken Alfredo
1. Mix the spices and coat the chicken. Combine the chili powder, cumin, oregano, paprika, black pepper, salt, and cayenne in a small bowl. Put the chicken strips in a larger bowl, add the honey and half the seasoning blend, and toss until the coating is distributed. Reserve the remaining half for the sauce.
2. Cook the penne separately. Bring a pot of water to a boil and cook the 1/2 pound penne according to its package directions until al dente. Check a piece for a tender exterior and a slight bite in the center, then drain. The pasta will be tossed into the finished sauce rather than cooked in the cream.
3. Brown the seasoned chicken. Heat the olive oil in a large skillet over medium heat. Add the chicken strips and cook until browned and the thickest pieces reach 165°F. Adjust the heat if the honey coating darkens too quickly. Transfer the cooked chicken to a plate so it does not continue simmering while the sauce is made.
4. Soften the onion and add garlic. Add the tablespoon of butter and chopped onion to the skillet over medium heat. Stir until the onion is soft rather than merely browned, then add the minced garlic for about 1 minute, until fragrant. The fresh butter supplies the fat for this stage after the chicken has been lifted out; lower the heat if the pan residue darkens rapidly.
5. Build the tomato cheddar sauce. Stir in the diced tomatoes with their juices and the reserved half of the seasoning blend. Bring to a low simmer, then gradually add the cream while stirring. Lower the heat and melt the shredded cheddar in small handfuls, stirring each addition smooth before the next. Gentle heat keeps the cheese from becoming grainy, while the tomato juices give the finished sauce a loose, creamy consistency.
6. Coat the chicken and pasta. Remove the skillet from the heat, then fold in the cooked chicken, its juices, and the drained penne. The hot sauce coats the chicken without another simmer, helping the strips stay tender. Turn the pasta until sauce reaches its grooves, finish with cilantro, and divide into four portions with chicken in each.
Serving Suggestions
Serve southwest chicken alfredo warm with cilantro scattered over the top and chicken distributed through each portion. A green salad or a simple vegetable side gives some contrast to the cream and cheese. Bread can be served alongside if you want it, but it is not required to complete the sauce. Divide the chicken and pasta together so each of the four portions gets both.

Storage and Reheating
Refrigerate leftover southwest chicken Alfredo promptly in a covered, shallow container and use within 3 to 4 days. Reheat to 165°F, stirring the pasta and sauce so the center heats evenly. A small splash of liquid can loosen sauce absorbed by the noodles. Freezing may change the texture of the dairy sauce, so the freshly made or refrigerated dish is the more predictable option.

Tips and Variations
Watch the honey-coated chicken while it browns and lower the heat if the coating darkens too quickly. A dark surface does not tell you the center has reached 165°F.
Grate the cheddar before making the sauce and melt it gradually over low heat. Keep the tomatoes and cream at a gentle simmer instead of boiling aggressively.
Cayenne adds a sharper heat beyond the chili powder. Reduce it for a milder variation, and offer extra heat at the table instead of making the entire pan hotter than everyone wants.
Frequently Asked Questions
Is this pasta a classic Parmesan Alfredo?
No. This version uses cheddar, cream, tomatoes, and Southwest seasonings. The cheese gives it a different flavor from a classic Parmesan sauce.
Do I cook the penne in this sauce?
Cook it separately according to its package directions, drain, and toss it into the finished sauce. The listed cream is for the sauce, not for boiling dry pasta.
How do I divide the spices?
Mix all the measured seasonings first. Use half with the chicken and honey, then add the remaining half with the tomatoes.
How can I keep the chicken in southwest chicken alfredo from drying out?
Keep the strips similar in thickness so they finish together. Melt the cheese before returning the cooked chicken, then coat it off the heat.
Can I use a different pasta shape for southwest chicken alfredo?
Yes. Keep the same dry weight and use the package cooking directions. Choose a shape that catches the sauce, and cook it al dente before the final toss.
