This oven baked 5-ingredient forgotten Memorial Day cookout casserole is exactly the kind of thing my mother-in-law used to slide into the oven before anyone else pulled into the driveway. While everyone assumed she fussed for hours over the grill, this was quietly bubbling away inside—creamy, cheesy, a little smoky from the baked beans, and totally addictive. It uses just five pantry-friendly ingredients, goes straight into one dish, and bakes up into those golden, caramelized edges that make you want to scrape the pan clean. It’s the kind of secret side dish that explains why she always had an empty casserole dish to take home.
Serve this casserole hot, straight from the oven, alongside grilled burgers, hot dogs, or brats. It pairs really well with something crisp and fresh like coleslaw, a simple green salad, or sliced watermelon to balance the richness. I like to set it on the buffet with corn on the cob, potato chips, and pickles so people can scoop a big spoonful right next to their main. Leftovers reheat nicely and make a cozy side for grilled chicken or sausages later in the week.
