We love making chicken noodle casseroles for dinner. They are easy to make and can be made ahead of time for an easy weeknight meal. I was in the mood for Mexican food, so I decided to make a Chicken Fajita Noodle Casserole. Chicken Fajitas are my favorite Mexican dish, so I was excited to see how the casserole turned out. Well, it turned out delicious! I mean seriously delicious! Chicken, fajita seasoning, bell peppers, onions, noodles, sour cream, cream of chicken soup and cheese! How could it be bad?!?!?!

This is super easy to make. Start with cooking the egg noodles. While the noodles are cooking, sauté some chicken tossed in fajita seasoning with bell peppers and onions. Finally, combine sour cream, cream of chicken soup, Mexican cheese, the cooked noodles and chicken mixture. Spread into a baking dish and pop it in the oven.

This casserole can be made ahead of time and refrigerated or frozen for later. This makes a ton, so you can split it between two pans and freeze one for later. LOVE being able to pull a casserole out of the freezer for a quick weeknight meal!

Feel free to top the casserole with your favorite taco toppings. I like to add a dollop of sour cream and some homemade salsa. We serve this casserole with some black beans, green beans, or a chopped salad. Here are a few of our favorite recipes from the blog that go great with this yummy chicken casserole:

  1. I love that it used whole amounts of food, I hate having half a can of anything in the fridge, always seems to get thrown out any ways. I used 1 small onion instead of half a large for this reason as well. It say that it feeds 6 people and that is the honest truth right there, I fed 2 people and have 8-1 cup servings to eat in the freezer! I’ll update whether freezing cooked turns out okay.

  2. They weren’t wrong when they said it makes stacks…. Enough to feed 5, three times over. Nice dish.

    1. I know this question is from quite some time ago, hopefully you figured out something that worked for you! I have a few different options that work, so I thought it might be helpful for others who may have the same question if I shared them anyway.
      In most recipes you can use plain Greek Yogurt in place of Sour cream and it works fine, same amount, no difference really except maybe a bit more tang from the yogurt. I don’t see any reason why it wouldn’t work in this dish.
      I sometimes use French Onion dip, or some type of dip like that in place of Sour Cream if I don’t have Sour Cream, and I’ve always had wonderful success with that. (It’s very rare that I don’t have Sour Cream though, we LOVE IT, so I don’t typically make substitutions) I do like French Onion dip in potato dishes though, Funeral Potatoes being my all time favorite. I actually use the French Onion dip instead of Sour Cream purposely when making that dish because it adds such incredible flavor! Although everyone LOVES that dish, it’s probably the number one most requested potato dish, it can be a fairly bland, adding the dip makes a HUGE DIFFERENCE!
      If you do use a “dip” make sure that what you choose is going to go well with the flavors of the dish that you’re making. I may be wrong, I haven’t made this recipe yet, (although I’ve NEVER made a PC dish that we didn’t LOVE!!!! 😘), but I think that one of the Queso Cheese dips might be pretty incredible in this particular casserole, something like the Tostitos brand I believe, it’s always on the shelves with the chips, of course there are lots of queso dips out there now and most are MUCH BETTER than the original one I just mentioned…
      Sometimes you can substitute Cream Cheese in place of Sour Cream, I can’t guarantee how it would work in this recipe but I wouldn’t think it would be an issue. When I do use Cream Cheese as a sub then I will typically put it in the microwave to soften it, then it can easily be incorporated into the “Cream of Soup” portion of the recipe. You could also add it to the pan with the chicken, peppers and onion ONLY AFTER they’re done, you will need to turn the heat down to low and then just put it in long enough to melt it, making it easy to mix in with the other ingredients.
      Of course this is NOT my recipe, it’s Stephanie’s, so hopefully she will speak up if I’ve given advice that isn’t going to work well 😉 I can tell you that you can’t go wrong with her recipes, they’re all incredible!! 💜💜💜
