Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the high-protein pasta according to package directions until just shy of al dente. Remember to reserve some of the cooking water for later to adjust the consistency of the sauce.
Step 2: Marinate the Chicken
While the pasta is cooking, combine the chicken pieces with olive oil, smoked paprika, garlic powder, cumin, salt, and black pepper in a bowl. Let it sit for about 8–10 minutes to absorb all the flavors.
Step 3: Sauté the Chicken
Heat a skillet over medium-high heat and add olive oil and butter. Once the butter has melted, add the chicken, cooking it in a single layer until it’s browned and fully cooked through. Transfer it to a plate and cover it with foil to keep warm.
Step 4: Sauté the Veggies
Lower the heat to medium and add the sliced red onion and green bell pepper to the same skillet. Sauté them until they have softened and started to char, scraping up any browned bits left in the pan.
Step 5: Add Seasonings
Stir in garlic powder, cumin, regular paprika, salt, and black pepper along with the tomato paste. Cook for about a minute or two while stirring to enhance the flavors of the spices and toast the paste.
Step 6: Create the Sauce
Pour in the chicken stock and use a wooden spoon to deglaze the pan, scraping up all the delicious bits. Lower the heat and whisk in the softened cream cheese until everything is smooth and creamy.
Step 7: Incorporate Cheese
Gradually stir in the shredded cheddar until it melts completely and forms a glossy, rich sauce. If the sauce seems too thick, add some reserved pasta water little by little until you reach your desired consistency.
Step 8: Combine Chicken and Pasta
Return the drained pasta and cooked chicken to the skillet, tossing everything gently to combine. Use more reserved pasta water if necessary to ensure the sauce coats every piece of pasta evenly.
Step 9: Finish and Serve
Top with chopped parsley and a squeeze of fresh lime juice for a bright finish. Let it rest off the heat for a couple of minutes before serving to allow the flavors to settle.
Tips and Mistakes to Avoid
– Avoid overcooking the pasta; it should be al dente so it holds up in the sauce.
– If the chicken isn’t browned, it may not have enough flavor. Let it cook without stirring too much at first.
– Remember that the sauce will thicken slightly as it cools; adjust with pasta water as needed.
Storage Tips
Store leftovers in an airtight container in the fridge for up to three days. You can freeze this dish for a month, but the texture may change slightly upon reheating. To reheat, simply warm it in a saucepan on low, adding a splash of chicken stock or water to restore creaminess. This pasta also makes a great meal prep option for weekday lunches.
Variations and Substitutions
For a higher protein option, try swapping out the chicken for flavored turkey or even shrimp. If you’re looking to go vegetarian, seasoned tofu works beautifully instead. For a lower-carb alternative, zucchini noodles can be a fun twist while keeping everything light.
Why This Recipe Is The Real Deal
The combination of protein-rich ingredients not only fills you up but also keeps you satisfied longer, making it perfect for dinner or lunch meal prep. Personally, I love that it’s so adaptable; whether you’ve got chicken or veggies on hand, you can throw it all together and make it work.

Instructions
Preparation Steps
- Bring a large pot of salted water to a boil and cook the pasta until just shy of al dente according to package directions. Reserve 1 cup of the cooking water, then drain and set the pasta aside.
- While the pasta cooks, combine the chicken pieces, 1 tbsp olive oil, smoked paprika, 1 tsp garlic powder, 1 tsp cumin, 1/2 tsp salt and 1/4 tsp black pepper in a bowl. Toss well and let sit 8–10 minutes to absorb the flavors (or refrigerate up to 30 minutes).
- Heat a large skillet over medium-high heat and add 1 tbsp olive oil and the butter. Once the butter melts and the pan is hot, add the chicken in a single layer. Cook, stirring occasionally, about 6–8 minutes until pieces are browned and cooked through. Transfer the chicken to a plate and tent with foil to keep warm.
- Reduce heat to medium. In the same skillet add the sliced red onion and green pepper. Sauté until softened and slightly charred, about 5 minutes, scraping up any browned bits from the bottom of the pan.
- Stir in 1 tsp garlic powder, 1 tsp ground cumin, 1 tsp paprika, 1/2 tsp salt, 1/4 tsp pepper and the tomato paste. Cook while stirring constantly for 1–2 minutes to toast the paste and deepen the flavor.
- Pour in the chicken stock and use a wooden spoon to deglaze, loosening any stuck bits. Lower the heat to medium-low and whisk in the softened cream cheese until a smooth sauce forms.
- Add the shredded cheddar a handful at a time, stirring until melted and glossy. If the sauce looks too thick, stir in up to 1/2 cup of the reserved pasta water to reach a silky consistency.
- Return the drained pasta and the cooked chicken to the skillet. Toss gently to combine and warm through; add more reserved pasta water as needed to loosen the sauce so it coats the pasta evenly.
- Finish with the chopped parsley and a squeeze of fresh lime (if using) for brightness. Let the pan rest off the heat for 2 minutes before serving so the sauce settles.
