Get your largest skillet heating over medium-high heat. Toss in that ground beef and break it up with a spoon. You want it nicely browned, no pink bits left. Honestly, this is where a lot of the flavor starts, so don't rush it. Drain off any excess grease – I usually just tilt the pan and scoop it out with a spoon, a bit messy, but effective.

Once the beef is browned and drained, add your diced onion and minced garlic to the pan. Sauté them until the onion is softened and translucent, and you can smell that amazing garlicky aroma filling your kitchen. This usually takes about 5-7 minutes. I always make sure the garlic doesn't burn; that's a sad, bitter flavor nobody wants in their Ground Beef Hobo Casserole.

Now for the fun part! Grab your 9x13 baking dish. Spread that seasoned ground beef and onion mixture evenly across the bottom. Next, arrange a layer of your thinly sliced potatoes right over the beef. Try to overlap them slightly so you get a nice, even potato blanket. I sometimes get a bit messy here, but it's okay, it'll all bake together beautifully.

Sprinkle your mixed vegetables (peas, carrots, corn, whatever you fancy) over the potato layer. This adds color and a lovely freshness to the rich casserole. I always make sure they're evenly distributed so every bite of this Ground Beef Hobo Casserole gets some veggie goodness. Don't worry if it looks a bit piled high, it will settle down as it bakes.

In a medium bowl, whisk together your cream of mushroom soup and milk until it's smooth and creamy. This is the magic sauce that ties everything together. Season it with a little salt and pepper here, too, because every layer deserves flavor! I once forgot to whisk it properly, and had lumps, oops. Pour this creamy mixture evenly over the vegetables and potatoes.

Preheat your oven to 375°F (190°C). Sprinkle a generous layer of shredded cheddar cheese over the top of the casserole. This is where it gets that golden, bubbly crust! Pop it into your preheated oven for about 45-50 minutes, or until the potatoes are tender and the cheese is melted and gloriously golden brown. The whole kitchen will smell incredible, a true sign your Ground Beef Hobo Casserole is ready!
