This cozy ground beef casserole is one of my favorite ways to bring everyone to the table with minimal fuss. It layers well-seasoned beef, creamy sauce, crispy potatoes, and a cheesy golden topping into a dish that’s always a hit. Whether it’s a busy weeknight or a casual weekend dinner, this is a reliable go-to I’ve returned to time and time again.
I first made this casserole when I had leftover ground beef and hash browns in the fridge and needed something easy. Now it’s the meal my family asks for most on chilly evenings.
