Bell Peppers – Adds a sweet crunch and classic fajita flavor; use a mix of red, yellow, and green for a colorful dish.
Onions – Brings a rich, slightly sweet flavor when sautéed, balancing the spice.
Pasta Sauce – Forms the saucy base; use a spicy variety for extra heat or mild for a more subtle flavor.
Chopped Green Chilies – Adds a smoky kick; adjust the amount based on your spice preference.
Shredded Taco Cheese – Melts beautifully into the pasta, adding creaminess and richness; a Mexican cheese blend works perfectly.

As many other good recipes, this pasta came together as my way of using up leftover Chipotle copycat fajitas. I made a huge batch of Chipotle-style grilled peppers and onions, and on the second day decided to toss them into some pasta along with a pasta sauce and a can of green chilies. And what’s the best way to garnish a pasta? Cheese, of course! Lots and lots of cheese! I threw in the whole package of shredded Mexican taco cheese, and this pasta turned out so perfect!

What’s the best way to extinguish the heat from spicy chilies? With melted cheese of course! Comforting melted gooey cheese makes the spicy sauce take on the whole new flavor dimension!

Serving Suggestions

Pair this spicy pasta with a Fresh Tomato Avocado Lettuce Salad and a zesty lime dressing for a refreshing contrast.
A side of warm, Buttery Garlic Cheese Bread is perfect for soaking up the flavorful sauce.
Transfer the pasta to a baking dish, sprinkle Costco Shredded Parmigiano Reggiano, and broil for a few minutes until golden and bubbly.
Serve with Juicy Grilled Boneless Chicken Thighs, Crispy Frozen Beer Battered Shrimp in Air Fryer, or Juicy Air Fryer Chicken Fajitas for extra heartiness.
A dollop of Authentic Mexican Guacamole or Creamy Salsa Dip with Sour Cream on top helps cool down the spice and adds creaminess.

Tips For Success

Cook Pasta Al Dente – Since the pasta will be mixed with the sauce and cheese, cooking it al dente prevents it from becoming too soft and mushy. Drain it well before adding to the pan.
Use a Variety of Bell Peppers – Using a mix of red, yellow, and green bell peppers adds color, sweetness, and depth to the dish.
Sauté Peppers and Onions Until Slightly Charred – Cooking them over medium-high heat until slightly browned brings out their natural sweetness and enhances the fajita flavor.
Adjust Spice Level to Taste – If you love heat, add extra chopped green chilies or a dash of cayenne pepper. If you prefer milder flavors, use a mild pasta sauce or reduce the chilies.
Let the Cheese Melt Completely – Stir well after adding the shredded taco cheese to ensure every bite is cheesy and creamy. If needed, cover the pot for a minute to help it melt faster.
Customize with Protein – This dish is delicious as a vegetarian meal, but you can add grilled chicken, shrimp, or beef for extra protein.
Serve Immediately – The cheese is best when hot and melty, so serve right after mixing for the ultimate gooey, comforting pasta experience!

Variations And Substitutions

Make It Spicier – Add diced jalapeños, a pinch of cayenne pepper, or a splash of hot sauce for an extra kick.
Mild Version – Use a mild pasta sauce and skip the green chilies to reduce the spice level while keeping the delicious fajita flavor.
Different Cheese Options – Swap taco cheese for cheddar, Monterey Jack, or a Mexican cheese blend for a different flavor.
Low-Carb Option – Replace regular pasta with zucchini noodles or spaghetti squash for a lower-carb alternative.
Gluten-Free Alternative – Use gluten-free pasta to make this dish completely gluten-free.
Protein Additions – Stir in cooked chicken, shrimp, or even ground turkey for extra protein. Black beans or pinto beans are great vegetarian options.
Creamier Texture – Add a splash of heavy cream or cream cheese to the sauce for a richer, creamier consistency.
Roasted Vegetables – Try roasting the bell peppers and onions for a smoky depth of flavor instead of pan-frying.
Add More Toppings – Garnish with fresh cilantro, diced avocado, or a squeeze of lime juice for extra freshness.
Make It a Baked Pasta – Transfer the cooked pasta to a baking dish, top with extra cheese, and bake at 375°F until golden and bubbly for a cheesy, baked version.
