Start by cooking your pasta shells just shy of al dente. Meanwhile, bring your oven up to a toasty 375°F and show some love to a 9x13 baking dish with a little greasing.
Grab your skillet, and let the ground beef dance with garlic powder, salt, and pepper until perfectly browned. It's a simple yet essential step that sets the stage for flavor.
With the beef beautifully browned, toss in the pasta, tomato soup, water, and half the cheese brigade. Give it a stir and let the ingredients get to know each other for a few minutes over the heat.
Once they're all cozy, pour the love into your prepared dish. Shower it with the remaining cheese, cover it up with foil like a tucked-in child, and let it bake for 20 minutes. Then peek inside, remove the foil, and bake for another 10 minutes until the cheese is not just melted, but bubbly and eager to greet you. For the grand finale, if you're craving a golden top, a quick flirt under the broiler will give you that picture-perfect cheese crust we all crave.
