Turn your oven up to 375°F. Lay a sheet of thick aluminum foil over a baking tray and coat it lightly with nonstick spray.
02 -
Scatter the frozen fries across the prepped tray so they form a single layer. Sprinkle with the salt and cracked pepper. Pop them into the oven for 20-25 minutes, keeping an eye on them. You want them crisp, not limp, since ovens differ.
03 -
As the fries bake, throw the ground beef and diced onions into a large skillet or stockpot over medium-high heat. Stir regularly until the beef is brown and cooked through—about 5-7 minutes. Drain any extra grease before moving on.
04 -
Turn the heat to medium, then mix in the mushroom soup, cheese soup, half-and-half, and Worcestershire sauce. Stir nonstop for a couple of minutes, then take it off the heat.

Coat a 9x13-inch casserole dish with nonstick spray. Pour the beef and soup combo into the bottom and spread it out evenly. Sprinkle 1 cup of shredded cheddar on top of the beef layer.
06 -
Grab the fries from the oven and layer them over the shredded cheese. Scatter the remaining 2 cups of cheddar on top to cover the fries completely.
07 -
Put the dish in the oven and bake for another 18-20 minutes. The cheese will be gooey, and the beef at the bottom will bubble slightly. Serve right away while it’s warm.
