First things first, peel and dice those potatoes into about 1/2-inch cubes. Pop 'em into a pot of cold, salted water, bring it to a boil, then simmer until they're fork-tender, about 10-15 minutes. This is where I always forget to salt the water, oops, but it makes a difference! Drain them well and set aside. You want them cooked but not mushy for this Ground Beef Potatoes Casserole.

While the potatoes are doing their thing, heat a large skillet or Dutch oven over medium-high heat. Add your ground beef and break it up with a spoon. Cook until it’s beautifully browned, crumbling as you go. Drain off any excess fat – this is key for a non-greasy casserole, trust me, I've skipped this step before and regretted it!

Reduce the heat to medium. Toss in your diced onion and cook until it softens and turns translucent, about 5-7 minutes. Then, stir in the minced garlic and cook for just another minute until fragrant. Don't let it burn; that's a sad smell and a ruined dish!

Stir in the tomato paste, dried thyme, and smoked paprika with the beef mixture, cooking for a minute to toast the spices. Pour in the beef broth and Worcestershire sauce. Bring it to a simmer, scraping up any browned bits from the bottom of the pan – that’s pure flavor right there! Let it simmer for 5-7 minutes until the sauce slightly thickens. Season with salt and pepper to your liking.

Preheat your oven to 375°F (190°C). Grab a 9x13 inch baking dish. Spread the savory ground beef mixture evenly across the bottom. Next, mash your cooked potatoes with the milk, butter, a pinch of salt, and pepper until smooth and creamy. I sometimes leave a few small lumps because I like that rustic texture, honestly.

Carefully spread the mashed potatoes over the Ground Beef Potatoes Casserole, making sure to seal the edges. Sprinkle that glorious shredded cheddar cheese generously over the top. Bake for 25-30 minutes, or until the casserole is bubbling around the edges and the cheese is melted and golden brown. Let it rest for 10 minutes before serving, if you can wait that long!
