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.
Serve these cheesy onion fries straight from the slow cooker on warm, with a big spoon for scooping. They’re awesome piled next to grilled burgers, hot dogs, or BBQ chicken, and they hold up well on a buffet table for parties.
