"Old potatoes" that are still edible (firm, no green spots, minimal sprouting) can be used in a wide variety of recipes. If the potatoes are wrinkled, shriveled, or have green spots, they should be composted or discarded to be safe.
Leftover potato recipes
Make gnocchi or grate them and make hash browns /latkes. You could also use them as filing for a meat pie. Or make soup and toss them in near the end so they just heat through.

If you notice several sprouts on your potato, take a few moments to assess the spud and make sure there aren't any other issues.
Signs of spoilage: • Softness or mushiness: If the potato feels soft or mushy, it's likely going bad. Sprouts: While sprouted potatoes are generally safe to eat if you remove the sprouts, excessive sprouting or mushy sprouts may indicate spoilage.
+ Can You Still Eat Sprouted Potatoes? Yes—but only if handled carefully. If the potato is still firm and not green, it can be salvaged by removing the sprouts and peeling the skin. However, if it's wrinkled, mushy, or has turned green, it's best to throw it out.
But shriveling potatoes that are softer or have sprouted eyes are safe to eat. Just trim off the sprouts and eyes and peel off any parts you don't want to eat. I've found the skins get tough and they don't make good baked potatoes or French fries. They do work fine for mashed potatoes.
Symptoms range from mild yellow mottling on leaves to tuber necrosis (dying cells), which eventually kills the plant. Some plants don't show any symptoms, which makes it difficult for seed growers to remove diseased plants and leaves whole fields vulnerable to infection. PVY does not harm people or animals.
Avoid sprouted or rotten potatoes: While you can compost potatoes, it's best to avoid sprouted or rotten ones. These can sprout in your compost pile or attract unwanted pests.

If you bake potatoes wrapped in aluminum foil, Keep them at 140°F or hotter until they are served, or. Refrigerate them with the foil loosened so they get air.
Potatoes that are soft, mushy, squeezable, or moist are past their prime. "If it feels soft to the touch or wilted or wrinkled, throw it away," said Silness. If you cut into a potato and it looks green, you should toss it.
A viewer recently asked, “Can I freeze potatoes?” Although you can't freeze raw potatoes (they discolor and the texture changes), if you suddenly have way more potatoes than you can use before they wrinkle, you can freeze some for a short period of time with the right preparation.
It's a great idea for potatoes that you think might start going bad. Boil them halfway through. Then you can shred some and freeze them for hash browns. Also cube them up and freeze them later for mashed potatoes.
However, if it's wrinkled, mushy, or has turned green, it's best to throw it out. + How to Safely Prepare Sprouted Potatoes 1️⃣ Remove the sprouts completely: Cut off all sprouts and any green areas. 2️⃣ Peel the potatoes: Since solanine is concentrated in the skin, peeling reduces the risk.
Mold on potatoes can indicate dangerous levels of solanine, a natural toxin that causes food poisoning. Discard the entire potato immediately, even if only a small area appears moldy, as toxins may have spread internally. Proper storage at 45-50°F (7-10°C) in a dark, well-ventilated space prevents mold growth.
High levels of glycoalkaloid are toxic to humans. Acute symptoms, which generally occur 30 minutes to 12 hours after ingestion, include nausea, vomiting, stomach and abdominal cramps, and diarrhoea.

Potatoes infected with PMTV can display both foliar and tuber symptoms: Tuber: distortions to the skin, deep cracking and rust-coloured arcs, streaks or flecks in the tuber flesh (also known as 'spraing'). See image 5 for details. Foliar: yellow colouration and distortion of the leaves (Figure 2).
A Profusion of Potato Possibilities
You can: chop them up and roast them; make home fries; make baked potato soup; stuff them and bake them again; add them to casseroles; make baked potatoes au gratin; make potato cakes, potato salad, potato skins, mashed potatoes, potato wedges, hash, hash browns, the list goes on.
No, shriveled or wrinkled potatoes should not be eaten.
The most common mistake when making mashed potatoes is overworking them with a blender, food processor, or mixer, which releases too much starch and turns them gluey or pasty instead of fluffy. Other frequent errors include using the wrong potatoes, not salting the cooking water, starting potatoes in boiling water, and adding cold butter/milk.
+ Can You Still Eat Sprouted Potatoes? Yes—but only if handled carefully. If the potato is still firm and not green, it can be salvaged by removing the sprouts and peeling the skin. However, if it's wrinkled, mushy, or has turned green, it's best to throw it out.
Most home processing methods like boiling, cooking, and frying potatoes have been shown to have minimal effects on solanine levels. For example, boiling potatoes reduces the α-chaconine and α-solanine levels by only 3.5% and 1.2% respectively, but microwaving potatoes reduces the alkaloid content by 15%.
The formation of glycoalkaloids in potatoes is increased by warm storage temperatures and exposure to light. Cooking potatoes by baking, boiling, frying, and microwaving does not eliminate glycoalkaloids. However, removing the potato's skin before cooking can reduce the glycoalkaloid content.
