Fajita Chicken Casserole: The Weeknight Dinner Winner You’ll Keep Coming Back To

Let’s talk about a recipe that checks all the boxes: easy, flavorful, comforting, and family-approved. Fajita Chicken Casserole is hands down one of those dishes that has earned a permanent spot in my weekly dinner rotation. It’s my go-to when I want something hearty and satisfying, but don’t want to stand over the stove for an hour.

If you love the bold flavors of chicken fajitas but want to skip the tortilla assembly line, this casserole is your dream come true.

What Makes It So Good?

Think sizzling fajita-style chicken, colorful bell peppers, and onions, all tossed in a perfectly seasoned blend of spices—then baked to bubbly, cheesy perfection. This casserole captures everything you love about fajitas, minus the mess. It’s creamy, melty, and packed with Tex-Mex flavor in every bite.

Oh, and did I mention it’s a one-dish wonder? That means fewer dishes to clean, and more time to enjoy your evening.

Perfect for Busy Weeknights

One of the reasons I adore this recipe is because it’s incredibly simple to throw together. Whether you use fresh chicken or leftover rotisserie, it comes together quickly and bakes while you handle everything else on your to-do list. It’s also great for meal prep—just portion it out and reheat throughout the week.
