Do you have an insatiable hunger for potatoes? Do you have a fully-sated hunger for complicated recipes and having to cook all the time? This version of Pommes Anna, simplified and altered to an extent that will make French people cry, might be the recipe for you!

Casserole dish of baked potato slices resting on a stove, showing the randomly-layered top is crispy and browned while the edges are fully-baked

I try to eat unreasonable amounts of potatoes every day, so I want a food that doesn't take a lot of time to make, can be stored and reheated, and remains palatable after eating it for every meal for months at a time. The advantages of this recipe are:

The main downsides are:

Recipe

Prep Time: 15-30 minutes

Cook Time: 1 hour

Servings: 8

Nutrition[1]:

If this is your whole diet, you may want to eat some eggs along with it.

Equipment

Safety Note: Always use mandoline guard!

Ingredients

Note: Recipe can be scaled to any baking dish. Fill dish with peeled potatoes to measure, then scale butter and salt proportionally.

Directions

  1. Pre-heat oven to 400° F.
  2. Peel the potatoes and then slice them thinly with a mandoline (I use the 2mm setting on mine). Cut any leftover potato pieces into thin strips. Add all of the potato to a very large bowl.

  1. Melt the butter.
  2. Add the salt to the potato slices and mix it in.
  3. Add the butter to the potato slices and mix it in.
  4. Add mixture to the casserole dish. Placing the slices edge-up or randomly (my preference) will give you the most varied and crispy texture. Placing the slices flat will give you a more consistent custardy interior. Pour any additional liquid at the bottom of your bowl over the top.

  1. Cover with aluminum foil and bake for 40 minutes.
  2. Uncover and bake for another 20 minutes.

  1. Let cool and then slice and eat, or cool entirely in the fridge for solid pretty-looking slices that reheat in 2 minutes in the microwave.

Question re: the mandoline: does the slicing side of this box grater look to be appropriate for slicing the potatoes for this recipe?

I actually have this exact box grater so I sacrificed a potato for science and determined:

  • The thickness looks a little smaller than I usually do but should be fine.
  • It's not quite as sharp as my mandoline so it might get tiring.
  • The slicer is very small, so you might have trouble with large potatoes. I usually cut potatoes on the small side (for smaller slices) anyway, so this might not be a problem.
  • You should get something to protect your hand since you'll definitely cut the tip of your finger off if you slice 6 lbs of potatoes like this without a guard.

One thing to keep in mind is that, from what I understand, ovens are very imprecise so you gotta exercise some judgement when using them. For example, even if you set your oven to 400°F, it might only reach 325°F. Especially if you open the oven to check on the food (that lets out a lot of heat).

I've also heard that when baking on sheet pans, you can get very different results based on how well seasoned your sheet pan is. That shouldn't affect this dish though since the intent is for the top to be the crispy part and that happens via convection rather than conduction. But maybe how high or low you place the baking dish in your oven will affect the crispiness.

That's a good point. I don't really know what I'm doing, so I'm not able to predict exact variations. I found that this worked relatively consistently no matter how I cooked it, but the version in the recipe above was the best.

I definitely endorse changing the recipe based on how it goes:

  • If it's not crispy enough, bake it longer uncovered, or increase the temperature, or move the pan closer to the top of the oven.
  • If the internal texture is crunchy/uncooked, bake it (covered) longer.
  • If the internal texture is too mushy, bake it (covered) shorter. You could also make the inside crispier by discarding the liquid released when you salt the potatoes, but you'd also need to adjust the amount of salt to make it taste good, and it would effect how it cooks.

I'm no chef, but I love to cook, and my thanksgiving meals are planned in spreadsheets with 10 minute increments of what goes where. Plus I currently live full-time in an RV so I've gotten used to improvising with nonstandard and less reliable tools. Take or leave my suggestions accordingly.

It's often a good idea, until and unless you know your oven really well, to put an oven thermometer in the oven on the rack and adjust accordingly. They're <$10. Try placing it in different spots and figure out how evenly or unevenly your oven heats, and how a pan in one spot affects temperature in another.

Composition and thickness of your pan also matters. Ovens heat from all sides, but it matters whether your food is sitting in glass, steel, thin aluminum, or thick aluminum. Cake mixes try to give different instructions for glass, metal, and dark metal, but it's going to vary by recipe.

And it matters whether you're using a convection or conventional oven. The standard advice is shorter times and lower temperatures for convection, but you might still get differences in terms of drying out the top before the bottom and center cook fully with convection. Maybe you have to cover it part of the time, for some recipes.

If you misjudge and want more crispiness, why not briefly broil at the end? Say you're trying to braise a roast in a pan next to, above, or below the dish of potatoes. Steam from the roast slows the cooking and prevents browning. Then when you take the roast out to rest, you have a couple of minutes to broil before serving.

As another variation, I wonder how it'd come out if you used a sheet pan instead of a baking dish. I'd think that you'd get more crispy bits because of the increase in surface area of potato that is exposed to heat. Personally I'm a big fan of those crispy bits!

You'd probably need to use multiple sheet pans, but that doesn't seem like much of an inconvenience. You can also vary the crispiness by varying the amount of exposed surface area. Like, even if you use a sheet pan you can still kinda stack the potatoes on top of one another in order to reduce the exposed surface area.

I agree that more crispy bits is good. The recipe above optimizes for not being annoying to make, but doing the exact same thing and spreading the mixture on two sheet pans might work (and it would probably have a much shorter bake time).

I suspect the crispier version would be harder to store and wouldn't reheat as well though.

Yukon Golds are objectively the best potato

Correct :-)

Do you have a specific type of gold you use? The best I can reliably get are the organic golds from Trader Joe's, they come in a 3 lb bag. When I'm making home fries or anything diced I also really like The Little Potato Company.

Edit to add: now you have me wanting to make potatoes au gratin. It's been a while since I've made a good cheese sauce.

Not best for mashing, therefore not best for knishes, therefore not best!

(I agree that Yukon Golds are very good for many other applications, though.)

Interesting, why don't you like them for mashing? That's specifically what I like them best for. Although IIUC a knish needs a different texture to hold together well. I also don't use golds for (unbreaded) potato cakes unless I mash them in advance and use them left over.
