Oven Roasted Sweet Potatoes and Onions is truthfully only my second-favorite way to eat sweet potatoes. My very favorite way is a whole sweet potato, rubbed in olive oil, kosher salt and black pepper and then roasted whole. The skin is so thin that you don’t even have to poke holes in it so steam can escape — eventually the skin will start breaking on its own, but it retains more of its steam this way and results in an unctuous dish that I then slather in butter and more salt and pepper. That’s dinner! The caveat to my favorite way is that it takes 45 minutes to an hour, depending on the size of the potato. I don’t always have a full hour to wait for dinner. This recipe is much faster, especially if you cut the sweet potato smaller than the 2-inch pieces that the recipe calls for.
In addition, we have a small oven, and can’t easily fit multiple dishes in the oven at once. Cut smaller than the 2-inch pieces, this recipe will cook up in the amount of time that you are waiting for a roasted chicken or some other large long-roasting item to rest and be ready for slicing.
I adore sweet potatoes, both the lighter-colored ones and the darker red ones that, here anyway, are often labeled as “red garnett yams.” I never had real sweet potatoes growing up; you see, my mother doesn’t like sweet potatoes at all. As a result, the only sweet potato I had ever met was the sweet potato casserole my grandmother made at Thanksgiving — yes, that one: whole marshmallows, corn flakes and canned sweet potato. I even liked that. Nothing, however, can hold a candle to a real sweet potato.
I enjoy this dish leftover for lunch the next day, with a bag of corn chips to provide some texture. Yum!
