I’ve always understood that beans and rice is the defacto struggle meal. It’s hard to beat them for sheer dollars-to-calories ratio, and may even be less expensive than potatoes.

I’m sure you’re aware - and I empathize with your situation - but eating a variety is best if you’re able to manage it. Potatoes can go a long way to stretching a diet, but aren’t very nutritionally diverse on their own.

A few less expensive supplements I’ve used in the past are peanut butter, and eggs. There’s often a deal to be had by shopping seasonally - pumpkins are in right now and I get a surprising amount of mileage out of them.

Personally I love green onions with potatoes. They’re not very nutritionally dense, but they’re a pleasing aromatic and you can get a bundle for around a dollar. If you place your onions in an open jar of water on the counter, they’ll continue to grow. I usually regrow my onions 4-5 times from a single bunch and plain water, a handy frugal tip

But assuming potatoes are the only or main item on the menu, there’s an impressive degree of versatility in their preparation. Ultimately that usually adds up to mashed, baked, boiled, or fried.

Potatoes make an excellent soup. Even on their own - a local place here does a side dish which is just a quarter potato simmered in miso / vegetable stock. If you’re doing other ingredients, the potato can be made into a thickener for soup - corn chowder is an inexpensive meal that I’ve leaned heavily on in the past.

If you make a large batch of mashed potatoes, you can repurpose the leftovers for other meals. Mix with flour and you’ve got croquettes or potato pancakes. You can pretty much just toss them in a pan and refry them. If fish is available to you, you can mince a can into a potato / flour mixture and then fry it to get a tasty fish cake.

You can jazz up a baked potato into what’s known as a Hasselbeck potato if you want a fun presentation. Essentially you score the potato into several thin segments and drizzle it with oil while baking. It has a pretty unique look.

This last one is a bit off the deep end - but it’s a local dish here and something that our family does for major gatherings. It’s called Rappie Pie, or Pate a la Rapure, or sometimes Potats Rappe. It’s a bit of a process, but the only essential ingredients are potatoes and soup stock. It can be a ton of work and not for the faint of heart, but it’s a rather unique preparation and genuinely comfort food for me. We like ours fairly runny - we sometimes call it Potato Jello

This recipe appears fairly accurate, but I’ll try to summarize.

1. Grate potatoes into pulp then squeeze to remove the starch. This is the most laborious part of the process, so it’s common for people to do this communally or to take a shortcut by buying a processed potato block.

2. Gradually mix potato mixture into boiling broth. Whisk until smooth

3. Pour into a greased pan, halfway through adding additional fillings if you have them. This is commonly served as a meaty dish with chicken, rabbit, or venison, but I’ve made it vegetarian or plain before too.

4. Bake until a crispy skin forms. Serve while hot, leftovers can be frozen or refrigerated, then reheated in the oven or a skillet

Anyway, good luck to you. I hope food security is in your future, nobody should have to go hungry 😞

I have some thoughts on this, but do want to echo what one other poster said about bulk buying ingredients. If you’re in the US, Costco accepts EBT at all stores, and I believe you don’t need a membership. I would also look online to find any and all local food assistance programs to help augment what you will have available to have available, because some rice and beans could absolutely change your life with some potatoes.

For recipes:

• Potato soup/chowder (good storage)
• Korean stews if you can get your hands on a big bag of Korean red pepper powder one time that lasts years, usually
• Scalloped potatoes
• Mashed potatoes (good storage)
• Kenji’s Crispiest Potatoes Ever
• Real Slow Baked Potatoes (1+ hour in the oven, no foil) though this doesn’t store well
• Broth and potatoes (some people try to rebrand as Melting Potatoes
• Oven Baked Fries

Some of these may need more ingredients, like a base broth, but most should be pretty minimal. I have all kinds of food buying and providing hacks if you need more tips, or mention a general area of where you’re at. Someone else may also know of other programs you can take advantage of.

This isn’t quite the question you asked, but my best advice based on being in survival mode some time ago is: Get a Costco membership or borrow someone’s card, and start to get small batches of $50-100 worth of groceries from there at a time. Plan it ahead for what you’ll need for the couple of weeks coming up. Big sacks of rice or flour, cases of tinned bean or veggies, milk and eggs or cheese, peanut butter, cheese and oranges once you’ve got a reserve of the staples. Potatoes, olive oil, bread, Annie’s mac and cheese.

Even if you’re only buying 3-5 things with each trip, your money will go pretty far and it’s wonderful to have some basic stuff in the cupboard all month and then be spending your money on filling in new stuff you want, instead of just on survival.

I have no potato recipes for the now, this is just some stuff for later that worked for me.

Cheap and easy for me means shepherd’s pie or pasta with sauce. Both are simple to make, cheap, and healthy. They also can freeze well so you can make a big batch on sundays for the whole week.

Potatoes are really versatile.

Hash browns are quick and easy, shred the potato, line it flat on a plate, cover with paper towel and microwave for two minutes, then fry. Add in some grated onion or other root vegetables and fry in chicken fat for latkes, great with apple sauce or sour cream (if using the latter, use vegetable oil to be very traditional)

Roasted potatoes with dried herbs and a squeeze of lemon, also easy, not as quick. About 35 min in a 425°F oven.

Potato dumplings or spatzle are also good. Boil peeled potatoes then mash with flour, egg, and some fat to form a dough. Then form into small balls and boil again or, more traditionally, grate the dough into boiling water. You can season the dough with some nutmeg for a simple but earthy touch.

Potatoes can make a good soup, too. Sweat onions, garlic, other alium like leeks, and maybe celery, add in peeled, inch cubed potato, cover with liquid (stock, water with bouillon, or just water) by like an inch, boil until the potatoes are fork tender then mash the crap outta it until its thick and homogeneous. Ideally you’d blend this, but you said equipment is limited. Make it rich with butter or milk. Err on the side of less liquid, it’s easier to thin a thick soup than it is to thicken a thin one without burning stuff on the bottom of the pot.

When I am super lazy and when it’s cold outside I usually make potato stew. Ingredients are afaik cheap all around the world. It goes something like this:

Cut and roast some onion. Peel and cut some carrots into bits and add it into the pot. Add some concentrated tomato paste, salt and pepper. Let it continue simmering at low temperature. Peel and cut some potatoes. Add them to the pot and pour in some water. Just enough to cover everything. Let it simmer at the lowest temperature for an hour or two or five. Doesn’t matter really. It’s potato stew, not beef wellington.

I actually like this. It’s one of the easiest things I occasionally cook and it reminds me of my childhood. The good times at least.

This isn’t a potato suggestion, but a food pantry suggestion. They’re generally run by your local food bank if you have one, or sometimes churches. Instead of giving you money to spend on food, they just give you actual food that has been donated. The food they give you is quite varied.

Try different types of potatoes. The common “Russets are rejects from the french fry industry”. (direct quote from a Potato farmer I met a few years ago - I’m guessing he doesn’t grow Russets and always take the quote with some salt). Different types of potatoes work well with different cooking styles.

(everything else I have to say has been well covered by others)

A couple of years ago I picked up a recipe that someone shared in response to a post about three ingredient recipes. I partially boil potatoes, dump them on a cookie sheet, fork smash them, pour butter over the top, and throw them in the oven until they’re a little brown and crispy on the tips, and then salt. They are so good and you could sprinkle a little bit of anything on top of this -any kind of seasoning. A little bit bacon would be good, or ham or leftover taco meat or some spicy chicken. It’s kind of a good base for whatever leftovers you might have in your fridge and it has a little better presentation than just mashed potatoes. People are always amazed at how good it is. Who knew that potatoes, butter and salt were good together?
