Twice Baked Sweet Potato Casserole

Twice Baked Sweet Potato Casserole  | My Engineered Nutrition

I absolutely love sweet potatoes - the firm, light-skinned, pale flesh variety. Not to be confused with the soft, copper-skinned and orange flesh variety which stores often label as 'yams'.

Confusing, right? I've shared this article before, but if you want to nerd out on sweet potato varieties, read this article from The Kitchn.

Now that we are both on the same page about which glorious tuberous root I'm referring to, let's continue..

I recently discovered that these pale fleshed sweet potatoes boil and mash BEAUTIFULLY...and quickly, I might add. One of my gripes I've always had with sweet potatoes is that they take for-ev-errr to bake or roast. And let's be real here, I'm usually starving when I actually start preparing my meals and the thought of waiting 45 minutes to an hour for them is unbearable and I'm not motivated enough to wait.  

All it takes is some boiling water and chopped sweet potatoes, and in just 10 MINUTES you've got yourself some wonderful mashed sweet potatoes.

Now, you could stop right after boiling and mashing the sweet potatoes and be well on your merry way eating as I've shown on through my Instagram HERE, HERE, HERE and HERE. However, these mashed potatoes can be oh-so-much better when transformed into this Twice Baked Casserole. 

This casserole is a breeze to make and it reheats wonderfully - perfect for those weeknight dinners when you are in need of something quick! This warm and creamy casserole is made of soft mashed sweet potatoes, low-fat or nonfat cheddar cheese, nonfat Greek yogurt garlic and green onions. It's like a loaded baked potato...but in casserole form.
