Ingredients Method

Ingredients

  

• Chicken: 1.5 pounds boneless, skinless chicken breasts (or thighs if you prefer)
• Pasta: 12 ounces whole-wheat penne or high-protein pasta
• Veggies: 1 large onion (yellow or red), 3 bell peppers (mixed colors), 2–3 garlic cloves
• Spices: Chili powder, smoked paprika, ground cumin, oregano, garlic powder, onion powder, salt, black pepper
• Liquids: Low-sodium chicken broth (1.5 cups), lime (1–2 for juice and zest)
• Creaminess: 3/4 cup plain Greek yogurt (2% or 0%) or low-fat cream cheese
• Cheese: 1/2 cup shredded Mexican blend or reduced-fat cheddar (optional)
• Oil: Olive oil or avocado oil
• Fresh toppings: Cilantro, green onions, jalapeño (optional)
• Extras (optional): Canned fire-roasted tomatoes (1/2 cup, drained) or a splash of hot sauce

Method

 

1. Cook the pasta: Bring a large pot of salted water to a boil. Add pasta and cook until al dente according to package directions. Reserve 1/2 cup pasta water, drain, and set aside.
2. Mix the fajita seasoning: In a small bowl, combine 2 teaspoons chili powder, 1 teaspoon smoked paprika, 1 teaspoon cumin, 1/2 teaspoon oregano, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
3. Prep the chicken: Slice chicken into thin strips. Pat dry and toss with half the seasoning and 1 teaspoon oil.
4. Sear the chicken: Heat a large skillet over medium-high. Add 1 tablespoon oil. Cook chicken in a single layer, 3–4 minutes per side, until browned and cooked through. Transfer to a plate and keep warm.
5. Sauté the veggies: In the same skillet, add another teaspoon oil if needed. Add sliced onion and bell peppers with a pinch of salt. Cook 5–7 minutes, stirring occasionally, until tender with light char. Add minced garlic and the remaining seasoning; cook 30 seconds until fragrant.
6. Build the sauce: Pour in chicken broth and bring to a simmer, scraping up any browned bits. Stir in the cooked chicken (and fire-roasted tomatoes if using). Lower heat to medium-low.
7. Make it creamy: In a small bowl, whisk Greek yogurt with a few tablespoons of warm broth from the pan to temper it. Stir the tempered yogurt into the skillet. Keep heat low to prevent curdling. Add a splash of reserved pasta water if you want a looser sauce.
8. Add the pasta: Toss in the cooked pasta and fold to coat. Squeeze in the juice of 1 lime and add lime zest. Taste and adjust salt, pepper, and heat. If using, sprinkle in the cheese and let it melt.
9. Finish and serve: Top with chopped cilantro, green onions, and sliced jalapeño if you like it spicy. Serve hot with extra lime wedges.

Keeping It Fresh

Store leftovers in an airtight container for up to 4 days. The flavors actually deepen after a night in the fridge. Reheat gently on the stovetop over low heat or in the microwave at 50–70% power to keep the sauce smooth.

If it thickens, add a splash of broth or water and stir.

For freezing, skip the yogurt and cheese, then freeze the chicken-pepper mix and pasta separately for up to 2 months. When ready to eat, reheat, then stir in fresh yogurt and cheese to finish. This approach keeps the sauce creamy and prevents separation.

Health Benefits

• High-quality protein: Chicken breast and Greek yogurt deliver a strong protein hit to support muscle repair and satiety.
• Fiber and micronutrients: Whole-wheat or legume-based pasta adds fiber, while peppers and onions bring vitamin C, antioxidants, and natural sweetness.
• Lighter creaminess: Greek yogurt replaces heavy cream, trimming saturated fat while adding calcium and probiotics.
• Balanced carbs: Pairing lean protein with complex carbs helps steady energy and keeps you full longer.

Common Mistakes to Avoid

• Overcooking the chicken: Thin strips cook fast.

  Brown them, then pull them off the heat to stay juicy.

• Curdling the yogurt: Temper the yogurt with warm liquid and keep the heat low when adding it to the pan.
• Skipping pasta water: A little starchy water helps the sauce cling to the pasta and keeps it silky.
• Under-seasoning: Taste at the end. A final pinch of salt or squeeze of lime can wake up the whole dish.
• Crowding the pan: If the chicken steams instead of sears, cook it in two batches for better flavor.

Alternatives

• Protein swaps: Use turkey breast, shrimp, or extra-firm tofu (pressed and seared). For tofu, toss with cornstarch and the seasoning before pan-frying.
• Dairy-free: Use a thick, unsweetened dairy-free yogurt or a cashew cream.

  Choose a dairy-free cheese or skip it.

• Low-carb: Swap pasta for zucchini noodles or spaghetti squash. Reduce broth and add yogurt gradually so the sauce doesn’t get watery.
• Gluten-free: Use certified gluten-free pasta and check your spices for cross-contamination.
• Extra veggies: Add mushrooms, spinach, or corn. Fold delicate greens in at the end so they just wilt.
• Smokier heat: Add chipotle in adobo or a pinch of cayenne for depth and warmth.

FAQ

Can I make this in one pot?

Yes, cook the pasta in the same skillet after searing the chicken and sautéing the veggies by adding extra broth and simmering until the pasta is tender.

Stir often and add liquid as needed. Temper in the yogurt at the end.

What’s the best pasta shape for this?

Penne, rotini, or fusilli work well because their ridges catch the sauce. Choose whole-wheat or a high-protein chickpea or lentil pasta if you want even more protein and fiber.

How do I keep the peppers crisp-tender?

Use high heat, don’t overcrowd the pan, and avoid over-stirring.

Let them sit for a minute to char, then toss. They’ll finish softening once the sauce comes together.

Can I meal prep this for the week?

Absolutely. Portion into containers and store the lime wedges separately.

Reheat gently and add a splash of water or broth to refresh the sauce. Top with fresh herbs right before eating.

What if I don’t have Greek yogurt?

Use low-fat cream cheese, light sour cream, or a mix of evaporated milk and a little cornstarch. Add slowly over low heat to keep the sauce smooth.

How spicy is it?

As written, it’s mild to medium.

For more heat, add jalapeño, chipotle, or extra chili powder. For less, reduce the chili powder and skip spicy toppings.

Can I use rotisserie chicken?

Yes. Shred about 4 cups, warm it with the sautéed peppers, and add seasoning and broth.

Since it’s already cooked, skip the sear and fold it in just long enough to heat through before adding yogurt.

How can I thicken a runny sauce?

Simmer on low to reduce slightly, add a bit of cheese, or stir in a teaspoon of cornstarch mixed with cold water. Go slowly to avoid over-thickening.
