Easy Cheeseburger and Mashed Potato Casserole

This is another one of my grandmother’s recipes, and my sister’s favorite meal. It is classic comfort food sure to fill your belly on a cold day, or great for whipping up when you’ve got a crowd to feed. The mashed potatoes take a little time, but the end result is completely worth it. Alternatively, you can use leftover mashed potatoes from another meal. This casserole takes few ingredients, most of which you’ll likely have on hand.

Ground Beef

First, you’ll need to brown some ground beef and onion.

Boiling Potatoes

Meanwhile, boil some potatoes. These ones are peeled because my mom hates potato skins and I was cooking for her, but if it were up to me, I’d leave the skins on. They add flavor and texture and contain vitamins and fiber.

Ragu Cheese Sauce

Drain the ground beef and add a whole jar of Ragu Cheese Sauce. Shh, don’t tell anyone I cheated and didn’t make my own cheese sauce!

Cheesy Hamburger and Potato Casserole Oven

Mash the potatoes with butter and sour cream, then layer the beef and mashed potatoes in a 9×13 glass casserole dish. Cover with foil and bake at 350 for 15 minutes; then remove the foil and bake an additional 15 minutes.
