Instructions

In a large saucepan, cover the peeled potato chunks with cold water by 1 inch. Bring to a boil, then reduce to a simmer and cook uncovered until tender, about 15 minutes. Drain thoroughly and set aside.
In a medium saucepan, combine milk, butter, cabbage, green onions, salt, and pepper. Bring to a bare simmer over medium heat and cook, stirring occasionally, until the cabbage is tender but still vibrant, about 10–15 minutes.
Add the drained potatoes to the cabbage mixture. Using a potato masher, mash everything together until creamy and well combined. Avoid using a food processor or stand mixer, as overworking the potatoes can make them gluey.
Taste and adjust seasoning with additional salt and pepper if needed. Serve warm, topped with an extra pat of butter if desired.

Notes

– Choose russet potatoes: They yield a light, fluffy mash that absorbs flavors beautifully.

– Avoid overcooking the cabbage: It should be tender but still hold its shape and color.

– Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Freeze individual portions for longer storage; thaw overnight in the fridge before reheating. Reheat gently on the stovetop or in the microwave, adding a splash of milk or broth to restore creaminess.

– Customizations: Swap cabbage for kale, spinach, or Swiss chard. Stir in diced leeks, roasted garlic, or crispy bacon bits for extra flavor.
