Tips for Making Potatoes Au Gratin With Gruyere Cheese

Wondering what to make with potatoes? We’re telling you, cheesy au gratin potatoes are certainly one of the best potato recipes of all time. Even better is you can make it in advance! Just refer to our FAQs below to learn how to prepare this dish ahead of time.

Meanwhile, here are some tips and tricks to help you make the best au gratin potatoes:

  • Use the right kind of potatoes. Meals with potatoes always start by picking the right kind of potatoes. For this recipe, use high-starch baking potatoes, such as russet potatoes and Yukon Gold potatoes. Their insides turn out tender and fluffy when baked, making for a yummy potato casserole that everyone will rave about. 
  • Slice the potatoes thinly and evenly. When preparing your homemade au gratin potatoes, make sure that you cut the spuds into uniform-sized thin slices so they cook evenly. The cream sauce will also seep in easily between the thinly-sliced spuds, resulting in creamier potatoes au gratin with gruyere.  Luckily, the slicing process will be much easier and quicker with the help of a high-quality mandoline.
  • Use cheese with sharp, bold flavors. Gruyere cheese is the best cheese for au gratin potatoes. It lends a rich and nutty taste, balancing out the creaminess of the dish. Although, if you don’t have gruyere on hand, you can also explore some of the best cheeses to replace it, such as gouda, parmesan, and cheddar cheese. You can even use a combination of gruyere and parmesan for a more decadent result!
  • Shred the cheese on your own. Instead of buying pre-shredded cheese, you should shred your own cheese from a block. Not only is it economical, but freshly shredded cheese also tastes better and melts more smoothly.
  • Season the cream sauce. This recipe for potatoes au gratin uses nutmeg, salt, and freshly ground black pepper to add wonderful flavors.  Feel free to incorporate paprika, garlic, and fresh thyme into the dish as well. Green onions, chives, and rosemary are also welcome additions!
  • Top your potato au gratin with breadcrumbs. Adding some breadcrumbs is optional. But if a crunchy topping delights you, then sprinkle the breadcrumbs on top after pouring the creamy sauce. Apart from providing fantastic texture, the breadcrumb topping can also absorb some of the fat and oil during baking.
  • Cover the potatoes au gratin with foil. If you notice that the top of your dish is browning too quickly, take it out of the oven and try covering it with  a sheet of aluminum foil. You can also do this before popping the casserole into the oven. Just uncover the dish once the potatoes have finished baking, and bake the potatoes again until the top crisps up and turns deliciously brown.

Frequently Asked Questions

What’s the difference between scalloped potatoes and au gratin?

Both scalloped potatoes and au gratin are baked in a baking or casserole dish and have creamy elements. Despite those similarities, they have a few differences that set them apart. Traditionally, a scalloped potatoes recipe does not include cheese, whereas au gratin potatoes have grated cheese in between layers. Another difference between these two potato casseroles lies in how the potatoes are cut. For instance, the potato slices in this au gratin are a bit thinner than in a regular dish of cheesy scalloped potatoes and ham.

Can you prepare potatoes au gratin with gruyere cheese ahead of time?

Yes, you can prepare potatoes au gratin ahead of time, specifically 24 hours in advance. After layering the potatoes and cream sauce, cover the dish with a plastic wrap or aluminum foil and store it in the fridge. Keep in mind that you have to take it out of the refrigerator at least 30 minutes before placing it in the oven.
