I still remember throwing this together on a busy Tuesday night with nothing but a chicken breast, some leftover bell peppers, and a box of whole wheat pasta staring back at me from the pantry.

Everything You Need to Make This Creamy Fajita Pasta

I always recommend prepping all your ingredients before turning on the heat. This recipe moves quickly once it gets going, so having everything measured and ready makes the whole process smooth. Pro tip: use full-fat Greek yogurt if you want an even richer, creamier sauce.

• 1 lb boneless, skinless chicken breast – cut into bite-sized pieces
• 8 oz whole wheat pasta
• 1 red bell pepper – sliced
• 1 green bell pepper – sliced
• 1 yellow onion – sliced
• 3 cloves garlic – minced (fresh garlic makes a noticeable difference here)
• 1 cup fat-free Greek yogurt (I prefer full-fat for a silkier finish)
• 1/2 cup chicken broth
• 2 tablespoons fajita seasoning (homemade blends help you control the sodium)
• 1 tablespoon olive oil
• 1/4 cup fresh cilantro – chopped
• 1 lime – juiced
• Salt and pepper to taste

Step-by-Step Instructions for High Protein Chicken Fajita Pasta

I recommend reading through all the steps before you start cooking. This one-pan dinner comes together in stages, and knowing what is coming next keeps everything running smoothly.

Step 1: Cook the pasta according to package directions, but pull it out one minute before the package says it is done. It will finish cooking in the skillet. Drain and set aside.

Step 2: Heat olive oil in a large skillet over medium-high heat. Add chicken pieces in a single layer and cook for 5 to 7 minutes until golden on the outside and fully cooked through with no pink in the center. Remove chicken from the skillet and set it aside on a plate.

Step 3: In the same skillet, add the sliced bell peppers and onion. Cook for 5 to 7 minutes until they are tender but still have a slight bite. Add the minced garlic and cook for one more minute until fragrant. You will smell that fajita aroma really start to build right here.

Step 4: Stir in the fajita seasoning, chicken broth, and cooked pasta. Toss everything together and let it simmer for 2 to 3 minutes. Watch the liquid here. Do not let it cook off completely or the sauce will turn dry before you add the yogurt.

Step 5: Remove the skillet from the heat completely before the next step. This is the most important technique in the whole recipe. Stir in the Greek yogurt off the heat so it does not curdle. Mix until the sauce looks smooth and evenly coats the pasta.

Step 6: Return the cooked chicken to the skillet and toss everything together until well coated.

Step 7: Stir in fresh cilantro and lime juice. Taste and adjust with salt and pepper. Serve hot and enjoy your high protein chicken fajita pasta right away.

Best Sides and Toppings to Serve with This Fajita Pasta

The bold, smoky flavors in this dish pair well with fresh, simple additions that balance the richness of the creamy fajita sauce. Here are some favorite pairings for this high protein chicken pasta.

Lime wedges: A squeeze of extra lime right before eating brightens the whole dish and sharpens the fajita flavor.

Shredded cheese: A sprinkle of sharp cheddar or Mexican blend melts right into the warm pasta and adds satisfying richness.

Sliced avocado: The natural creaminess complements the tangy yogurt sauce and adds healthy fats to the meal.

Tortilla chips: Great for scooping up extra sauce and adds a satisfying crunch against the soft pasta.

Simple green salad: A light salad with citrus vinaigrette keeps the meal feeling fresh and adds fiber alongside the protein-packed pasta.

How to Store and Reheat Your Chicken Fajita Pasta

This high protein chicken fajita pasta stores well, which makes it a solid choice for weekly meal prep. Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, transfer cooled portions to a freezer-safe container and freeze for up to 3 months.

To reheat, add a small splash of chicken broth or water before microwaving to loosen the sauce back up. You can also reheat on the stovetop over low heat, stirring gently until warmed through.

Pro tip: this dish tastes even better the next day once the fajita seasoning has had more time to settle into the pasta. Making a double batch on Sunday for weekday lunches is genuinely worth it.
