My great-grandmother passed down this genius 4-ingredient depression era meal. It is shockingly filling, so cozy, and costs almost nothing to make!

This slow cooker 4-ingredient carrot and potato mash is the kind of humble, stick-to-your-ribs meal my great-grandmother leaned on during the Depression years. It uses the most basic pantry staples—potatoes, carrots, butter, and a little salt—to turn almost nothing into something warm, filling, and comforting. Everything simmers low and slow until the vegetables are soft enough to mash with the back of a spoon, giving you a rustic, pale yellow and bright orange mash with a pat of butter melting over the top. It’s the sort of cozy, budget-friendly dish that can be a simple supper on its own or a hearty side stretched across several plates.

Serve this carrot and potato mash in wide, shallow bowls with an extra pat of butter on top and a sprinkle of black pepper if you have it. It pairs well with simple protein like baked chicken thighs, a pan-fried pork chop, or even a couple of fried eggs for a very thrifty supper. Add a side of green beans, peas, or a simple cabbage slaw to round out the plate. Leftovers reheat nicely alongside meatloaf or roast beef, or can be used as a cozy base under stewed beans or leftover gravy.

Servings: 4

2 pounds russet or Yukon Gold potatoes, peeled and cut into 1-inch chunks

Peel the potatoes and cut them into rough 1-inch chunks. Peel the carrots and slice them into 1/2-inch rounds or small chunks so they cook at about the same rate as the potatoes.

Add the potatoes and carrots to the slow cooker in an even layer. Sprinkle the salt evenly over the vegetables.

Dot the top of the potatoes and carrots with 2 tablespoons of the butter, cutting it into small pieces so it melts and runs down between the vegetables as they cook.

Cover the slow cooker with the lid and cook on HIGH for 3 1/2 to 4 hours, or on LOW for 6 to 7 hours, until the potatoes and carrots are very tender when pierced with a fork.

When the vegetables are soft, add the remaining 2 tablespoons of butter directly to the slow cooker. Use a potato masher or a sturdy spoon to mash the potatoes and carrots together right in the crock until you reach a fluffy, slightly chunky texture. The mash should be pale yellow streaked with bright orange.

Taste and adjust the salt if needed. If the mash seems too thick, you can mash in a tablespoon or two of hot water from the slow cooker or the kettle to loosen it slightly, keeping the rustic texture.

Spoon the carrot and potato mash onto a warm plate or into a shallow bowl. Top each serving with a small extra pat of butter so it melts and pools into the warm vegetables before serving.

For a true Depression-era feel, keep the recipe as written and let the butter and salt do the work. If you’d like to stretch it further, you can add an extra potato or two without changing anything else. For a creamier mash, stir in a splash (2–4 tablespoons) of milk or leftover cooking liquid when mashing, though this will add a fifth ingredient. A pinch of black pepper or dried parsley on top is nice if you have it, but not necessary. To make it dairy-free, replace the butter with a mild-tasting oil or margarine, understanding it will lose some of the old-fashioned flavor. You can also turn this into a complete budget meal by serving it in a bowl with a ladle of hot broth or gravy over the top, or by mixing in a cup of cooked beans or leftover shredded meat to make it more substantial while still keeping costs very low.
