I know, Easter isn’t for a few months yet but I’m already busy in the kitchen testing new recipes for our Easter celebration…and for sharing with all of you, of course! This Easy Roasted Potato Casserole is a different take on roasted potatoes that’s beautifully colourful and looks a lot harder to make than it actually is!

tri-colour potato casserole in purple dish with sweet potatoes Roasted potatoes make a delicious side dish any time of the year but this three colour sliced potato casserole really makes a statement – which is why it’s perfect for a holiday dinner, either at Christmas or Easter. It’s simple to make, and if you have a mandoline it’s even easier. My mandoline slicer is from OXO Good Grips and I adore it – it’s easy to use, works perfectly every time, and it won’t break the bank! Check it out HERE (affiliate link).

Ingredients

  • 3 medium sweet potatoes
  • 5 medium red potatoes
  • 5 medium purple potatoes
  • 6 tablespoons olive oil
  • 1 tablespoon chopped fresh rosemary
  • 1 tablespoon chopped fresh thyme leaves
  • 7 cloves garlic finely minced or pressed
  • 2 teaspoons sea salt
  • 1 teaspoon fresh ground pepper
  • parmesan shavings for serving (optional)
US Customary - Metric

Instructions

  • Preheat your oven to 375 degrees Fahrenheit.
  • Using a mandoline slicer or a sharp knife, slice the sweet potatoes, red potatoes, and purple potatoes into slices about 1/8 inch thick. Try to make the slices as even as possible, and choose potatoes with approximately the same circumference. You should end up with approximately 100-120 slices, depending on thickness.
  • Add the potato slices to a large bowl and toss well with the olive oil, rosemary, thyme, garlic, sea salt, and pepper until the potatoes are evenly coated.
  • Arrange the potato slices in your choice of casserole or baking dish (approximately 9-inch by 13-inch in size, preferably oval or round in shape) in a spiral pattern, alternating sweet, red and then purple slices to create a patterned design (if you wish).
  • If there is any leftover oil and herb mixture, pour it evenly over the potatoes you've arranges in the baking dish.
  • Bake, uncovered, for about 30-35 minutes, or just until the potatoes are fork tender.
  • Serve immediately, with some shaved parmesan on top if desired.

Notes

One serving of this recipe is equal to about 10-12 slices of potatoes.
To make this side dish up to one day ahead of time, simply prepare it as directed and store it in the fridge, covered until ready to bake. Place the cold casserole in a cold oven and let it heat up slowly as the oven preheats. Then, bake as directed.
