What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples or easy to pick up at any grocery store, making this a no-brainer for quick meals.

• Chicken Breast: 1 pound (450g), cut into bite-sized pieces (I recommend fresh, not frozen, for best texture)
• Olive Oil: 2 tablespoons (adds richness and helps with sautéing)
• Bell Peppers: 2 medium (one red and one green, sliced thin for that classic fajita look)
• Yellow Onion: 1 medium, thinly sliced (brings sweetness and depth)
• Garlic: 3 cloves, minced (because garlic is life)
• Fajita Seasoning: 2 tablespoons (store-bought or homemade blend with chili powder, cumin, paprika, oregano, and a pinch of cayenne)
• Chicken Broth: 2 cups (480ml), preferably low sodium for control over saltiness)
• Uncooked Pasta: 8 ounces (225g) penne or rotini (these hold sauce well)
• Heavy Cream: 1/2 cup (120ml) (adds that creamy, dreamy texture)
• Shredded Cheddar Cheese: 1 1/2 cups (170g) (sharp cheddar is my go-to for punchy flavor)
• Shredded Monterey Jack or Mozzarella: 1/2 cup (optional, for extra melty goodness)
• Salt & Pepper: To taste
• Fresh Cilantro: A handful, chopped, for garnish (adds a fresh, zesty finish)
• Fresh Lime Juice: From half a lime, squeezed over before serving (brightens flavors and cuts richness)

Substitution tips: Use almond milk or oat milk with a bit of extra cheese for a lighter dairy option. Swap chicken with turkey or even tofu if you want a vegetarian twist (just skip the chicken broth for veggie broth). And if you want gluten-free, penne made from brown rice or chickpeas works beautifully.

Equipment Needed

• Large Deep Skillet or Wide Pot: Ideal for one-pot cooking; I personally use a 12-inch nonstick skillet that’s deep enough to hold all ingredients and liquids without splashing.
• Sharp Chef’s Knife: For slicing chicken, peppers, and onions precisely.
• Cutting Board: Preferably separate ones for meat and veggies to avoid cross-contamination.
• Wooden Spoon or Silicone Spatula: For stirring without scratching your cookware.
• Measuring Cups and Spoons: To keep seasonings and liquids on point.
• Colander (optional): If you want to rinse pasta before adding; though with this method, no need to pre-cook or rinse pasta.

If you don’t have a large skillet, a Dutch oven or deep saucepan will do just fine. Honestly, I’ve even made this in a big sauté pan with high sides. Just make sure it’s roomy enough to hold everything without crowding.

Preparation Method

1. Prep ingredients: Slice your bell peppers and onion thinly, mince garlic, and cut chicken into bite-sized pieces. This should take about 10 minutes.
2. Heat oil: Place your large skillet or pot over medium-high heat and add 2 tablespoons olive oil. Let it warm until shimmering but not smoking (about 1-2 minutes).
3. Sauté chicken: Add the chicken pieces in a single layer. Cook for 4-5 minutes, stirring occasionally until the chicken starts to brown but is not fully cooked through. You want some golden bits—that’s flavor gold.
4. Add veggies and garlic: Toss in sliced onions, bell peppers, and minced garlic. Cook for about 4 minutes, stirring, until veggies soften but still have a little crunch and the garlic is fragrant (watch it closely to avoid burning).
5. Season: Sprinkle in 2 tablespoons fajita seasoning, salt, and pepper. Stir well to coat everything evenly. The kitchen will start smelling incredible here.
6. Add liquids and pasta: Pour in 2 cups (480ml) chicken broth and 1/2 cup (120ml) heavy cream. Stir to combine. Then add 8 ounces (225g) uncooked pasta. Push the pasta down gently to submerge it in the liquid.
7. Simmer: Bring the mixture to a gentle boil, then reduce heat to medium-low. Cover with a lid slightly ajar and simmer for 12-15 minutes, stirring occasionally to prevent sticking. The pasta will absorb the liquid and flavors.
8. Check pasta: Taste the pasta at around 12 minutes. It should be tender but still have a tiny bite (al dente). If needed, add a splash more broth or water and cook a couple more minutes.
9. Add cheese: Turn off the heat and stir in 1 1/2 cups (170g) shredded cheddar and 1/2 cup shredded Monterey Jack or mozzarella if using. Mix until cheese melts into a creamy sauce that coats every strand of pasta and chunk of chicken.
10. Finish and garnish: Squeeze fresh lime juice over the top and sprinkle chopped cilantro. Give it one last gentle stir.
11. Serve hot: Dish out immediately for that melty, cheesy goodness. You can also add a dollop of sour cream or sliced avocado on top if you’re feeling fancy!

Pro tip: If the sauce feels too thick, a splash of broth or even water will loosen it up perfectly without losing flavor. And be patient with the simmering—the pasta needs time to soak up all that chicken and fajita goodness.

Cooking Tips & Techniques

Here’s what I learned after a few “oops” moments making this recipe:

• Don’t overcrowd the pan: For best browning on chicken, cook in batches if needed. Otherwise, the meat steams instead of sears, and you lose that deep flavor.
• Use fresh fajita seasoning: If you use pre-mixed blends, check the salt level first. Too much salt can make the dish overpowering.
• Keep an eye on the pasta: Since it cooks right in the sauce, stirring occasionally prevents sticking and uneven cooking.
• Layer your flavors: Adding garlic and veggies after the chicken browns keeps everything vibrant and prevents mushiness.
• Multitasking helps: While the pasta simmers, you can prep garnishes or set the table—just don’t wander too far from the stove!
• Cheese choice matters: Sharp cheddar brings bold flavor; Monterey Jack adds creamy meltiness. Combine for the perfect texture.
• Leftover magic: Pasta thickens as it cools—add a splash of milk or broth when reheating to bring it back to creamy life.

Variations & Adaptations

This recipe is a blank canvas for your taste buds. Here are some ways I’ve switched it up:

• Vegetarian Version: Swap chicken for firm tofu or sautéed mushrooms, and use veggie broth instead of chicken.
• Spicy Kick: Add diced jalapeños or a pinch of cayenne with the fajita seasoning for heat that wakes up your palate.
• Low-Carb Twist: Use spiralized zucchini or shirataki noodles in place of pasta, reducing cooking time accordingly.
• Seasonal Veggies: Toss in corn kernels, cherry tomatoes, or zucchini during the sauté step for extra color and flavor.
• Dairy-Free Option: Use dairy-free cream and cheese alternatives; nutritional yeast can add that cheesy flavor punch.

My personal favorite? Adding a handful of black beans and swapping cheddar for pepper jack cheese for a southwestern vibe that’s just a bit more adventurous.

Serving & Storage Suggestions

Serve this one-pot cheesy chicken fajita pasta steaming hot, right out of the pan. It pairs beautifully with a simple green salad or some crunchy tortilla chips for texture contrast. For beverages, a cold cerveza or a sparkling lime soda works wonders.

Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of broth or milk and heat gently on the stovetop or microwave to keep the sauce creamy and smooth. This pasta actually tastes even better the next day when the flavors have had time to meld together.

If you want to freeze it, portion into freezer-safe containers and thaw overnight in the fridge before reheating. Just keep in mind the texture might soften a bit after freezing, but all that cheesy goodness remains totally satisfying.
