These 4-ingredient slow cooker cheesy onion fries are my kind of
holiday hack: dump everything in, walk away, and come back to a cozy,
melty, ridiculously good side dish that tastes like loaded diner fries. I
started making this for Memorial Day when I realized my oven was
already packed with burgers, brats, and baked beans.
Using frozen crinkle-cut fries means zero peeling or chopping, and
the slow cooker keeps them hot and cheesy for hours—perfect for grazing
guests and busy hosts who don’t want to babysit the stove.
