Ingredients
Method
- Cook the pasta: Bring a large pot of salted water to a boil. Cook the pasta until just shy of al dente. Reserve 1/2 cup of pasta water, then drain.
- Season the chicken: Pat the sliced chicken dry. Toss with 1–1.5 tablespoons Cajun seasoning, a pinch of salt, and pepper.
- Sear the chicken: Heat olive oil in a large skillet over medium-high. Add chicken in a single layer. Sear 3–4 minutes per side until browned and cooked through. Transfer to a plate and tent loosely with foil.
- Sweat the aromatics: Lower heat to medium. Add butter. Stir in onion and peppers with a pinch of salt. Cook 4–6 minutes until softened and lightly caramelized. Add garlic and cook 30 seconds until fragrant.
- Bloom the spices: Sprinkle in the remaining Cajun seasoning and stir 20–30 seconds. If using, add tomato paste and cook 1 minute to concentrate flavor.
- Build the sauce: Pour in chicken broth and simmer 2–3 minutes, scraping up browned bits. Stir in heavy cream and bring to a gentle simmer.
- Temper the yogurt: In a small bowl, whisk Greek yogurt with a few spoonfuls of hot sauce from the pan until smooth. Stir the tempered yogurt into the skillet to prevent curdling.
- Add cheese and adjust: Stir in Parmesan until melted. If the sauce is too thick, loosen with a splash of pasta water. Taste and adjust salt, pepper, and Cajun seasoning.
- Combine: Add the drained pasta and cooked chicken (plus any juices) to the skillet. Toss until the pasta is well coated and everything is hot.
- Finish: Squeeze in a little lemon juice to brighten. Garnish with chopped parsley or green onions. Serve immediately.

Benefits of This Recipe
- High-protein balance: Chicken and Greek yogurt boost protein without making the dish feel heavy.
- Steady energy: Protein plus pasta gives a satisfying, longer-lasting meal.
- Flexible flavor: Works with smoked paprika, extra garlic, or a splash of hot sauce to match your mood.
- Great for leftovers: The sauce thickens slightly by day two and tastes even richer.
- Family-friendly: Keep the heat mild for kids and add more spice at the table.
Pitfalls to Watch Out For
- Curdling yogurt: Always temper Greek yogurt with hot sauce from the pan before adding. Keep the heat gentle once it’s in.
- Overcooked chicken: Thin slices cook fast.
Pull them as soon as they’re done to stay juicy.
- Too salty: Cajun blends vary. Taste your seasoning and use low-sodium broth to stay in control.
- Gummy pasta: Cook just shy of al dente, then finish in the sauce so it absorbs flavor without turning mushy.
- Flat flavor: Don’t skip acid. A squeeze of lemon at the end brightens the whole dish.
Alternatives
- Protein swaps: Use shrimp, turkey, or sliced chicken thighs.
For a vegetarian option, try extra-firm tofu or chickpeas.
- Pasta options: High-protein pasta, whole wheat, or gluten-free varieties all work well.
- Dairy tweaks: Substitute half-and-half for cream to lighten it, or use full-fat Greek yogurt for extra richness. For dairy-free, try coconut milk and a dairy-free Parmesan-style cheese.
- Veg boosts: Add mushrooms, spinach, or zucchini for more fiber and texture.
- Lower carb: Swap half the pasta for zucchini noodles or hearts of palm pasta, then reduce sauce slightly so it clings.
FAQ
How spicy is Cajun seasoning?
It varies by brand. Some blends are mild and smoky, while others bring serious heat.
Start with less, taste, and add more until it hits your sweet spot.
Can I make it without heavy cream?
Yes. Use half-and-half or evaporated milk for a lighter sauce. Keep the heat low so the dairy doesn’t split, and lean on the Greek yogurt and Parmesan for body.
How do I keep the sauce from getting grainy?
Use freshly grated Parmesan, temper the Greek yogurt, and avoid boiling once the dairy is in.
Gentle heat keeps everything smooth.
Can I cook the chicken ahead?
Absolutely. Cook and slice the chicken up to 2 days ahead. Warm it in the sauce at the end so it stays tender and doesn’t dry out.
What’s the best pasta shape for this?
Short, ridged shapes like penne or rigatoni catch the creamy sauce and bits of chicken.
If using long pasta like fettuccine, reserve extra pasta water to help coat evenly.
How can I add even more protein?
Use high-protein pasta, increase the chicken to 2 pounds, or stir in a few tablespoons of plain whey isolate at the end off the heat, whisking well to avoid clumps.
Is this good for meal prep?
Yes. Portion into containers and refrigerate. Reheat with a splash of liquid to loosen the sauce and keep it creamy.
Can I use rotisserie chicken?
You can.
Toss shredded rotisserie chicken with a bit of Cajun seasoning and warm it in the sauce. Since it’s already cooked, add it at the end.
In Conclusion
High-Protein Creamy Cajun Chicken Pasta brings bold flavor, balanced macros, and simple technique to your table. It’s rich yet light enough to enjoy on a weeknight, and it’s easy to adapt to what you have on hand.
Keep the tips in mind, taste as you go, and finish with that fresh pop of lemon. You’ll get a bowl of comfort that’s satisfying, flexible, and reliably delicious.
