Sweet Potato Love

I love sweet potatoes roasted in the oven. I also adore cheese.  I’m a big fan of dairy, having grown up in NEPA, where the buffalo may not roam, but the Holsteins surely do.
Today, for Meatless Monday, I thought I would share a recipe that mingles and mixes both dairy and my love–the sweet potato.  I do not bake dishes like this in my iron skillet, though you may want to.  A skillet certainly adds the rustic feel, but I hate cleaning out cheese from an iron baking pan, so I’ll be using my glass pan to bake this yummy recipe.  If you try it, let me know what you think.
I think you can’t go wrong with sweet potato and cheese.
Sweet Potato Parmesan Gratin
Prep time: 10 mins
Cook time: 1 hour 15 mins
Total time: 1 hour 25 mins
A simple gratin featuring sweet potatoes, thyme, low-fat milk and parmesan cheese. Healthier than your average gratin yet just as satisfying.
Author: Minimalist Baker
Serves: 5-6
  • 2 organic sweet potatoes, sliced in thin rounds
  • 1 small red or yellow potato
  • ~ 1/4 tsp each salt and freshly ground pepper
  • 1 tsp thyme, roughly chopped (fresh or dried)
  • 3/4-1 cup Parmesan cheese, finely grated
  • 2 cups low-fat milk (I used 2%)
  1. Preheat the oven to 400 degrees.
  2. Butter or lightly oil a baking dish or cast iron skillet.
  3. Place the sliced potatoes in a bowl and season generously with salt and pepper. Add the thyme and half of the cheese and toss together.
  4. Transfer to the dish and pour on the milk. It should just cover the potatoes.
  5. Bake 30 minutes, remove from oven and carefully drain off a bit of the liquid (about 1/3 cup). Sprinkle the remaining cheese over the top and return to the oven.
  6. Bake another 45-50 minutes, until the milk is absorbed, the potatoes are soft and the top and edges are golden and around the edges. (Optional: drain off a bit more of the liquid as using low-fat milk instead cream can result in a bit of wateriness.)
  7. Let rest at least 20 minutes before serving so the juices can redistribute.
  8. Can be made ahead of time and reheated in the microwave or oven for serving.
* You can use cream or half and half instead of low-fat milk, but it will add a lot more fat and calories overall.
* You can substitute other cheeses besides parmesan, such as gouda or asiago.
