Baked Purple Sweet Potatoes with Cheesy White Beans

This recipe for baked purple sweet potatoes loaded with white beans, Parmesan cheese, garlic, and rosemary is for a loyal reader who asked for “more vegetables.” I think it’s been about 15 years, since a bicycle trip to Argentina and Chile, that I gave up being ovo-lacto vegetarian. But I’m always happy to eat more vegetables.

The inspiration

This recipe was inspired by a NY Times recipe of loaded sweet potatoes with black beans and cheddar. I find sweet potatoes so versatile, so you can expect to see more variations here in the future.

Tips and tricks for this recipe

I used Japanese white-fleshed, purple sweet potatoes (Satsumaimo) in this recipe. Feel free to substitute any sweet potato and figure a half to a full sweet potato per person, depending on the size of your sweet potato, the size of your person, and what else you are serving.

Many people get confused by the differences between sweet potatoes and yams. Traditionally the answer to this has been that we only have access to sweet potatoes in the United States. Those things we serve at Thanksgiving? They’re orange-fleshed sweet potatoes, not yams.

However… now that ube is growing in popularity, we are starting to see true yams. Because ube is a purple yam, not a purple sweet potato. But you can buy purple-fleshed sweet potatoes that are called Stokes purple sweet potatoes.

Confused? I think we all are. I think that we’ll be pulling out the Latin soon.

FAQs about this recipe for baked purple sweet potatoes

What should I serve with this?

This could be a side to a simple roast, or make it a complete vegetarian meal by adding some green vegetables and a salad.

What should I drink with this?

You would want a white wine, and I would probably choose a Viognier that could keep up with the sweetness in the sweet potato and beans as well as the earthiness of the garlic and the rosemary. Or you can never go wrong with a Sancerre from the Loire Valley.
