Grab a large skillet or a Dutch oven, and get it hot over medium-high heat. Toss in your ground beef and break it up with a spoon. You want it nice and browned, no pink bits left! Drain off any excess grease – this is where I sometimes forget and end up with a slightly oily casserole, oops. Once the beef is looking good, toss in your chopped onion and minced garlic. Let them soften up, about 5-7 minutes, until you can smell that amazing aroma filling your kitchen. Oh, the smell of garlic and onion cooking together is just heavenly.

Now for the good stuff! Pour in your undrained diced tomatoes, tomato sauce, and beef broth. Stir it all together, scraping up any browned bits from the bottom of the pan – that's pure flavor right there, don't leave it behind! Add your dried Italian seasoning, a good pinch of salt, and some freshly cracked black pepper. Give it a good stir and bring it to a gentle simmer. Let it bubble away for about 10 minutes, letting all those flavors meld together. This is where the magic starts to happen for your Cheesy Hamburger Casserole!

While the sauce is simmering, get a pot of salted water boiling for your elbow macaroni. Cook it according to package directions, but remember: al dente! It's going to bake more in the oven, so you don't want it overcooked now. Drain the pasta well, then add it directly to your simmering beef sauce. Stir it all until every piece of pasta is coated in that delicious, savory sauce. This step always makes me feel like a pro, seeing it all come together.

Take the skillet off the heat. Stir in about half of your shredded cheddar cheese and the milk. Stir, stir, stir until that cheese is all melted and gooey, making the sauce extra luscious. This is the part where I always sneak a little taste – can't help myself! The sauce should be creamy and rich, exactly what you want for a hearty Cheesy Hamburger Casserole. Taste and adjust seasonings if needed; maybe a little more pepper?

Pour the entire mixture into a 9x13 inch baking dish. Spread it out evenly, making sure all that deliciousness is distributed. Now, sprinkle the remaining shredded cheddar cheese generously over the top. Don't be shy here; we're going for cheesy goodness, after all! I always try to get an even layer, so every scoop gets that perfect cheesy crust.

Pop that dish into your preheated oven at 375°F (190°C) for about 20-25 minutes, or until the cheese on top is bubbly and beautifully golden brown. You'll know it's ready when your kitchen smells absolutely incredible and the edges are gently browned. Let it rest for a few minutes before serving – it helps the sauce set a bit and prevents it from being too soupy. This Cheesy Hamburger Casserole is best served warm, straight from the oven!
