Sweet Potato Mexican Casserole with Roasted Corn and Black Beans

Planning a night in this Cinco de Mayo rather than heading out? I’ve got just the dish for you!

This Sweet Potato Mexican Casserole with Roasted Corn and Black Beans is bold in both color and flavor! And best of all it’s loaded with nutrition, yet low in calories, allowing plenty of room for some churro cupcakes, Mexican brownies, or fried ice cream! Because let’s be real, when it comes to holidays and festive occasions, it all about the sweets, right?! Or am I alone in this thought process?Basically, I want my dinner plate full of veggies and wholesome foods, but then bring on the dessert!

If you’ve followed Lemons and Basil for long, you likely know that I love both sweet potatoes and spiralized veggies. Combining the two in this Sweet Potato Mexican Casserole just makes it even better. The inherent sweetness of the potatoes create a lovely base to this casserole, pairing beautifully with the roasted sweet corn and veggies. To balance the natural sweetness, the black beans add a subtle earthy flavor, that is then perfected by the Mexican inspired seasonings and layers of freshly grated cheese.

I mean, let’s be honest, is it really Mexican without a generous layer of cheese? Exactly.

Top it all off with a scoop of sour cream, fresh diced tomatoes, and avocados! Your tummy will not only be thanking you for fueling your body with real food, but your taste buds will be begging you for seconds.

If you don’t have a spiralizer at home, I’ve recently been using this one from WonderEsque and am currently loving it! It’s easy to use and easy to clean – two very important features. However, you could also thinly slice the sweet potatoes for the recipe rather than spiralizing them. It may increase your cook time by 5-10 so be sure to check the potatoes to see if they’re done before turning the oven off!

AOL was kind enough to include me in their judges panel for the Spring AOL Food Awards. I had so much fun receiving and testing several small kitchen appliances and gadgets. This spiralizer was among those received and has quickly become a favorite! I plan to share a few of my other favorites in the near future.

Happy cooking and Happy Cinco de Mayo!
