An Easy Chicken Dinner Idea

I’m a big fan of quick and easy dinners. I’ve always loved them, but even more so now that we have the twins. By the time they go to bed at night, I need dinner to be as simple as possible. This casserole meets those requirements and more.

In addition to being easy, it’s full of flavor and all the things we love most about Mexican food. It’s also a hearty casserole, since it’s made with pasta. The hubs has been telling me lately that he’s a big fan of pasta (hinting at me a bit, since I’ve been avoiding pasta as I try to lose the baby weight, LOL), so this meal is a great one. It’s something we both love and although we haven’t tried it on the boys yet, they so far seem to really like things with lots of flavor so I’m thinking this would be a hit.

How to Make This Mexican Chicken Casserole Recipe

The ingredients in this Mexican Chicken Casserole are pretty straightforward, which is part of what makes it so easy to put together. (You will find ingredient amounts in the recipe card.) Most of these are things we’d normally have in our pantry or fridge, aside from the chicken:

Penne pasta
Sour Cream
Black beans
Spices – Cumin, Garlic and Onion powder

To start, you’ll want to cook your pasta al dente. What that means is basically you want to cook it until it’s softened, but still a little firm. It’ll cook a little more when everything is heated in the oven, so no need to cook it until it’s too soft.

From there, you’ll combine everything else together, reserving a little bit of the cheese to put on top. Pour the mixture into a casserole dish, cover with that remaining cheese and bake for about 20 minutes, until everything is heated through and the cheese on top is melted.

Seriously, does it get any easier than that?!?

Tips for the Best Mexican Chicken Casserole

While I love this casserole just the way it is, you could of course try different options to suit your preferences.

– If you like a little less spice, leave out the jalapeños. Alternatively if you like more, consider adding red pepper flakes.
– You can definitely try out different kinds of pasta. The hubs is a big fan of penne, so that’s what we use.
– A great way to change up the flavor a bit is to try different salsas. We have a roasted tomato salsa that we love to use and it lends a bit of it’s smokey flavor to the casserole. Try out different ones!
