This slow cooker 3-ingredient potato and canned spinach dish is exactly the kind of frugal comfort food my grandmother leaned on when money was tight. She used to say she could stretch one humble can of spinach into a full family meal, and this was her Depression-era trick: bulk it out with potatoes and a little fat, then let it simmer low and slow until everything turned silky and satisfying. It’s simple, cozy, and filling—perfect for busy nights, tight grocery budgets, or those times you just want something warm and homey without a lot of fuss.
Serve this right from the slow cooker with a big spoon, letting everyone scoop soft potatoes and spinach into shallow bowls. It’s lovely with a sprinkle of black pepper on top and a slice of buttered bread or cornbread on the side to soak up the buttery juices. For a more complete meal, pair it with simple baked chicken thighs or sausages, or serve a fried egg on top of each bowl. A crisp green salad or sliced fresh tomatoes balances the richness and adds a bit of brightness to the plate.
Slow Cooker Potato and Canned SpinachServings: 4
Ingredients
2 pounds russet or Yukon Gold potatoes, peeled and cut into 1-inch chunks
1 (13–15 ounce) can spinach, drained (reserve liquid if you like a looser texture)
4 tablespoons butter, cut into small pieces
1 teaspoon salt, or to taste
1/2 teaspoon black pepper, or to taste
1/2 cup reserved spinach liquid or water (optional, for a saucier dish)
Directions
Prepare the potatoes by peeling them and cutting them into roughly 1-inch chunks so they cook evenly and get nice and tender.
Lightly grease the inside of your slow cooker crock if you like (this just helps with cleanup), then spread the potato chunks in an even layer on the bottom.
Sprinkle the salt and black pepper over the potatoes. If your family prefers to season at the table, you can go lighter on the salt here and add more later.
Drain the can of spinach over a bowl, saving the liquid if you might want a looser, more brothy texture. Gently break up the spinach with a fork so there aren’t any big clumps.
Scatter the drained spinach evenly over the potatoes in the slow cooker. Try to cover as much of the potato layer as you can so everything cooks together and the flavors mingle.
Dot the butter pieces all over the top of the spinach and potatoes. As the mixture cooks, the butter will melt down and form that simple, comforting buttery sauce that ties everything together.
If you prefer a saucier dish, pour about 1/4 to 1/2 cup of the reserved spinach liquid or water over the top. For a thicker, more spoonable mixture, you can skip this or use just a splash.
Cover the slow cooker with the lid and cook on LOW for 5 to 6 hours, or on HIGH for 2 1/2 to 3 hours, until the potatoes are very tender when pierced with a fork.
Once the potatoes are soft, gently stir the mixture from the bottom up, folding the potatoes and spinach together so the butter and seasonings coat everything. Be gentle so the potatoes stay in soft chunks rather than turning into full mashed potatoes.
Taste and adjust the salt and pepper if needed. If the mixture seems too dry, you can stir in a bit more of the reserved spinach liquid, a splash of water, or even an extra pat of butter to loosen it slightly.
Serve warm straight from the slow cooker, making sure each serving has a good mix of tender potato chunks and dark green spinach in that simple buttery sauce.
Variations & Tips
To keep this close to its Depression-era roots, the base recipe uses just potatoes, canned spinach, and butter as the three core ingredients, with simple salt and pepper for seasoning. You can easily adapt it to your family’s tastes, though. For picky eaters who shy away from visible greens, mash the mixture gently with a potato masher near the end of cooking so the spinach is more blended into the potatoes. If you want extra flavor on a budget, add a small sliced onion or a clove of minced garlic at the bottom with the potatoes (this technically adds ingredients but doesn’t change the spirit of the dish). For more protein, top each bowl with a fried or poached egg, or stir in some cooked crumbled bacon or leftover ham at the end. You can also sprinkle grated cheese over the top just before serving and let it melt slightly under the lid for a few minutes. For a lighter version, swap half or all of the butter for olive oil or a plant-based spread, and use water instead of the reserved spinach liquid if the canned liquid tastes too strong or salty. Food safety tips: Always wash and peel potatoes before using, and cut away any green spots or sprouted areas, as those can be bitter and unsafe to eat. Make sure your canned spinach is not dented, bulging, or past its expiration date before opening. Once cooked, keep the dish on the warm setting for no more than 2 hours, then refrigerate leftovers in a shallow container within 2 hours of cooking. Reheat leftovers thoroughly until steaming hot before serving, and use within 3 to 4 days.
