Potatoes Au Gratin

The deliciously gooey combination of sliced potatoes, cream, and cheesy goodness make this a recipe everyone will love. There’s just something about potatoes au gratin that makes it feel that little bit more “fancy” than regular mashed potatoes, but believe me when I say these potatoes are actually really simple to cook. This recipe is definitely one of my favorites, I mean –  how could you not love it?! it’s loaded with carbs and cheese and it’s basically the potato take on macaroni and cheese!

What Kind of Potatoes and Cheese Should I Use?

Russet potatoes (which I’ve used here) are most commonly used for au gratin potatoes because they’re super starchy and make a lovely creamy sauce. If you have some Yukon Gold potatoes, they can be used too. As for the cheese, it’s really up to you – I’ve used Parmesan here as it has a great peppery taste which I love! Gruyere is also a popular choice as it melts really well and has a deliciously nutty flavor! Other cheeses like mozzarella or Fontina will do just fine too, it really depends on your own preference!

How to Make Potatoes Au Gratin

  1. Preheat your oven to 400 degrees F.
  2. Grease a large casserole dish with butter.
  3. Combine the garlic and butter in a medium-sized saucepan over medium-high heat until the garlic is slightly browned.
  4. Reduce to medium heat, add the flour and combine. Whisk in the milk. Watch out for lumps of flour.
  5. Whisk in the cream and heat up.
  6. Add the cheese and stir until melted, then add salt. Continue to heat until the sauce has thickened. Remove from the heat.
  7. Add half of the potatoes to the casserole dish and pour half of the sauce on top. Add the rest of the potatoes and top with the remaining sauce. Cover and place in the oven to bake for around 60 minutes. Remove when fork-tender.
  8. Combine the Panko and Parmesan and sprinkle the crumb mixture over the casserole. Place back in oven until browned.

What’s the Difference Between Scalloped Potatoes and Potatoes Au Gratin?

These recipes get confused quite a lot as they’re so similar! But this question can be summed up in one sentence really: potatoes au gratin are made with cheese and scalloped potatoes aren’t! Scalloped potatoes are cooked in cream rather than cheese and are usually cut thicker. Another variation is that potatoes au gratin are also often topped with breadcrumbs (yum!).

Happy cooking!

Love,

    This recipe is amazing! I used red potatoes because that’s what I had on hand, added cubed ham, and added an extra cup of cheese.
