Sweet Potato Gratin

[heart_this] · Dec 12, 2022 · 2 Comments

Sweet Potato Gratin

A potato gratin with sweet potatoes and plenty of savoury melted cheese!

Potato gratin is a classic side dish that I always enjoy and it’s also nice with sweet potatoes! Sweet potatoes pair surprisingly well with a savoury cheese sauce! The recipe is pretty much the same as a regular potato gratin starting with a cheese sauce which is the simple combination of butter, flour, milk and cheese! The sauce is seasoned with garlic, thyme, and paprika and I like to use a white cheddar as the cheese. The sauce and thinly sliced sweet potatoes are layered in a pan, topped with more cheese and baked until tender. You can change the flavors up by using different cheese and seasonings; I like to use cheddar, chipotle chilies in adobo, and bacon! No matter how you make it, sweet potato gratin is an amazing side dish for any meal!

A potato gratin with sweet potatoes and plenty of savoury melted cheese!

ingredients
  • 3 tablespoons butter
  • 1 onion, finely diced
  • 1 clove garlic, chopped
  • 1 teaspoon thyme, chopped (or 1/2 teaspoon dried thyme)
  • 1 teaspoon sage, chopped (or 1/2 teaspoon dried sage)
  • 1 teaspoon smoked paprika
  • 3 tablespoons flour (gluten-free for gluten-free)
  • 2 cups milk
  • 1/2 cup sour cream
  • 1 pinch nutmeg (optional)
  • 1 cup cheddar cheese, shredded
  • salt and pepper to taste
  • 4 pounds sweet potatoes, thinly sliced
  • 1 cup cheddar cheese, shredded
directions
  1. Melt the butter in a large saucepan over medium heat, add the onion and cook until tender, about 5-7 minutes.
  2. Add the garlic, thyme, sage, paprika, and flour, mix and cook until fragrant, about a minute.
  3. Add the milk, sour cream, and nutmeg, bring to a simmer and cook until the sauce thickens, about 2-3 minutes.
  4. Add the cheese and cook until it melts, about a minute, before removing from heat and seasoning with salt and pepper to taste.
  5. Spread a few tablespoons of the sauce over the bottom of a 9×13 inch baking pan, layer the sweet potatoes in the pan alternating with sauce until all of the potatoes and sauce are in the pan.
  6. Sprinkle on the cheese and bake in a preheated 350F/180C oven until the potatoes are tender, about 45-60 minutes, before letting it rest for 20 minutes and enjoying!
Option: Use gouda, swiss, gruyere, asiago, or parmesan instead of the cheddar cheese.
Option: Add 4 ounces cream cheese to the cheese sauce.
Option: Add chopped chipotle chili peppers in adobo!
Option: Add 1 pinch of cinnamon!
Option: Add or garnish with 4 strips bacon, cooked and crumbled.
Note: I used a white cheddar in the photos.
