I’ll never forget the first time I tried to make this creamy chicken fajita pasta. I was so confident, throwing things in the pan like I was on a cooking show. I got distracted by my dog barking at a squirrel and totally burned the peppers and onions. The whole kitchen filled with smoke, and my pasta was a gloopy, sad mess. But I was determined to get it right because my friend told me it was the ultimate comfort food. After a few more tries (and fails), I finally nailed it, and now it’s my go-to easy dinner for my whole family.

Ingredients

1 lb boneless, skinless chicken breasts, sliced thin
2 tbsp olive oil
1 red bell pepper, sliced
1 green bell pepper, sliced
1 large yellow onion, sliced
3 cloves garlic, minced
1 packet (1 oz) fajita seasoning
1 cup heavy cream
1/2 cup chicken broth
1 cup shredded Monterey Jack cheese
8 oz penne pasta, uncooked
Salt and black pepper to taste
Fresh cilantro for garnish (optional)

That fajita seasoning packet is key, don’t be like me and try to mix your own spices the first time. I used way too much cumin and it tasted like I was eating a taco candle. And for the love of all that is good, slice your chicken thin. I didn’t once and ended up with chewy, undercooked chunks that nobody wanted to eat.

Directions

Bring a large pot of salted water to a boil and cook the penne according to package directions until al dente. Drain and set aside.
While the pasta cooks, heat the olive oil in a large skillet over medium-high heat.
Add the sliced chicken to the skillet and season with a pinch of salt and pepper. Cook for 5-6 minutes, until no longer pink. Remove chicken and set aside.
In the same skillet, add the sliced bell peppers and onion. Cook for 5-7 minutes, until they start to soften and get a little color.
Add the minced garlic and cook for another minute until fragrant.
Sprinkle the fajita seasoning over the veggies and stir to coat everything.
Pour in the chicken broth to deglaze the pan, scraping up any browned bits.
Reduce heat to medium-low and pour in the heavy cream. Stir well and let it simmer for 2-3 minutes.
Add the cooked chicken back to the skillet.
Gradually sprinkle in the shredded cheese, stirring constantly until it’s melted and the sauce is creamy.
Add the cooked and drained penne pasta to the skillet and toss everything together until the pasta is well coated in the sauce.
Garnish with fresh cilantro if you like, and serve immediately.

The step where you add the cheese is where I mess up most. If the heat is too high, the sauce can break and get all oily and gross. I’ve done it so many times. Now I always take the skillet off the heat for a minute before I stir the cheese in. It makes all the difference for a smooth, creamy sauce.

This dish is honestly the best for leftovers. I make a huge batch on Sunday and my husband takes it for lunch all week. It reheats surprisingly well, just needs a tiny splash of water or broth to loosen the sauce back up. It’s our favorite family favorite meal because it’s so customizable—the kids pick out the peppers, we add hot sauce, everyone’s happy.

I’ve tried to make it healthier, I really have. I swapped the heavy cream for half-and-half once and it was just… sad. It wasn’t creamy at all. So now I just accept that this is a treat and we have a big salad on the side. It’s all about balance, right? Sometimes you just need a big bowl of cheesy pasta comfort food.

The best part is that it’s basically a one-pot meal if you ignore the pasta pot. I’m all about minimizing dishes. I’ve even tried cooking the pasta right in the sauce to make it a true one-pot wonder, but it never turns out right. The pasta starch throws everything off. So two pots it is, and it’s totally worth the extra sink load.

Okay, yeah, the nutrition facts are a little scary. I’m not gonna lie. But like I said, we always have it with a salad to feel a little better about it. You could use a lower-fat cheese and maybe light cream, but I can’t promise it’ll be as good. For my gluten-free friends, just use your favorite GF pasta—it works great!

Ingredient Swaps

Ingredient	Substitution
Heavy Cream	Half-and-half (sauce will be less rich)
Monterey Jack Cheese	Pepper Jack or Cheddar
Chicken Breast	Thinly sliced steak or shrimp
Penne Pasta	Any short pasta like rigatoni or bowties

I’ve tried almost all of these swaps. The steak was amazing, but more expensive. The shrimp cooked way faster than the chicken, so I added it at the very end. Pepper Jack cheese is my favorite swap—it gives it a really nice kick. But do not, I repeat, do not use pre-shredded cheese with starch on it. It never melts right and you’ll get a weird grainy sauce.

Tips

Slice your chicken and veggies uniformly so everything cooks evenly.
Don’t crowd the pan when cooking the chicken. Cook it in two batches if you have to.
Let your cream and broth come to room temp before adding them to the hot pan to help prevent curdling.
Reserve a little pasta water before you drain it. If your sauce gets too thick, a splash of that starchy water will fix it.

The pasta water tip is something I learned the hard way. I made this for my in-laws and the sauce thickened up into a paste while I was getting everything to the table. I had no backup liquid and we just had to eat it. It was like eating cheesy cement. Now I always keep a cup of that water, just in case.

FAQ

Can I make this ahead of time?
You can, but the pasta will soak up a lot of the sauce. If I’m prepping it for later, I undercook the pasta just a bit and make a little extra sauce to have on the side for when I reheat it.

My sauce is too thin! How do I thicken it?
Oh man, I’ve been there. Let it simmer for a few more minutes off the heat—it will thicken as it sits. If you’re really in a pinch, a tiny sprinkle of flour whisked in can help, but go easy or it’ll taste pasty.

Is it really spicy?
Not really! The fajita seasoning is more flavorful than spicy. My kids eat it without complaining. If you want heat, add a diced jalapeño with the peppers or use Pepper Jack cheese. That’s how we do it for us grown-ups.
