Long day and you just want something easy and delicious? Grab this one-pan cheesy chicken fajita comfort dish loaded with creamy goodness. All the classic fajita flavors hang out with juicy chicken and plenty of bell peppers, finished off with a melty cheddar blanket. Weeknights are just easier—and tastier—when you throw this together. Fewer dishes, less stress, and everybody leaves the table happy.
I took this over to the neighbor's potluck last year and every scoop disappeared. My teenager claimed the last bit for their lunchbox the next day.
Irresistible Ingredients
- Cheddar cheese: gooey and melty on top, sharp cheddar gives the most punch—go for a block you can shred
- Cream cheese: turns the filling rich and smooth—let it warm up first for easy mixing
- Sour cream: adds a zing and makes things creamy, use full fat for the dreamiest texture
- Fajita seasoning mix: brings smoky and bright flavors, grab a favorite blend or whip up your own
- Small onion: sweetens things up and gives flavor depth, either yellow or sweet is fine
- Bell peppers: for that juicy crunch and color, mix red, yellow, and green if you can
- Boneless skinless chicken thighs or breasts: stays tender while soaking up all the flavor; chop even for fast cooking
- Olive oil: helps brown the chicken and veggies—extra virgin has the best taste
Simple Steps
- Finish & Enjoy:
- Wait about five minutes after baking so it’s easier to slice. Pop on avocado slices, extra sour cream, salsa, or guacamole before you dig in if you want something fresh on top
- Bake It Off:
- Put cheddar all across the top, then put everything in the oven at 350°F. Bake 10-15 minutes until bubbling and golden and the cheese is fully melted
- Mix It Together:
- Put your chicken back in with the peppers and onions. Add the fajita seasoning, cream cheese, and sour cream. Mix everything well until you have a creamy sauce and no cheese chunks
- Sauté the Peppers & Onion:
- Put the skillet back over the burner. Add onions and bell peppers. Stir every so often and let them get soft and a little brown at the edges for about six to eight minutes
- Get the Chicken Ready:
- Chop thighs or breasts into small bites for fast cooking. Heat olive oil in a big oven-safe pan on medium. Once it’s shimmering, toss in the chicken. Stir off and on for eight minutes till it’s browned and cooked with no pink. Scoop it out and set aside

I end up sneaking bell pepper bites straight out of the pan every time I make this. Their juicy sweetness just pops. My kid’s favorite part is grating the cheese—mostly because he gets an extra nibble.
How to Store
When everything's cooled off, cover up and pop it in the fridge for three days max. I think it’s best warmed in a 325°F oven just until the cheese is gooey again. Microwave works too if you’re in a rush. Wouldn’t freeze it—the dairy doesn’t love it—but it’s still perfect for speedy leftovers later in the week.
Swaps & Variations
If you’ve got leftover rotisserie chicken, use that to make things even faster. Sour cream can easily be swapped with Greek yogurt. Not big on cheddar? Monterey Jack or mozzarella melts nicely. Want more veggie action? Throw in corn or sliced zucchini with the peppers.
How to Serve
Spoon this over steamed rice or use cauliflower rice if you want fewer carbs. Stuff into tortillas for a Tex-Mex spin. Add chopped cilantro or some lime wedges on top for a pop of freshness. I like putting it next to lettuce and juicy tomato salad too.

A Little History
Classic fajitas got their start as a border meal in Northern Mexico and Texas, with grilled strips of meat and peppers. This cozy version brings all those fun flavors into one cheesy bake you can prep and share in no time. You still get those bold peppers, well-seasoned chicken, and all the color—no grill or heavy cast iron required.
Common Recipe Questions
- → Which chicken pieces should I use?
Either chicken thighs or breast meat will do the trick! Thighs give you juicier bites, but chopped-up breast stays soft if you don't overcook it in the pan.
- → Can you swap in cooked chicken that's ready to go?
For a quick fix, grab 5 to 6 cups of precooked chicken, shredded or in chunks. Stir everything together with your spices and creamy stuff, then slide it in the oven.
- → Should I make my own fajita spice mix or just buy it?
Either's fine! Homemade blend means you can tweak it your way. But a store packet or even taco seasoning works for busy nights.
- → How do I dial up the spice?
Throw in some sliced jalapeños, cayenne, or more chili powder with the peppers. Drop them in when you sauté or mix your seasonings for extra kick.
- → What's the tastiest way to serve this up?
Spoon on guac, salsa, avocado, or more sour cream if you've got it. Try it with some tortillas, or pile it up over regular or cauliflower rice.
- → Is it possible to prep this ahead?
You bet! Just build the whole thing the night before, cover it up, and stash it in the fridge. Pop it into the oven right before eating so it comes out hot and bubbly.
