Step 1

Preheat the oven to 350 degrees F.

Step 2

Grease a 9x13-inch baking dish.

Step 3

In a large skillet over medium-high heat, cook the beef, onion, and garlic until the beef is no longer pink, about 5-7 minutes.

Step 4

Drain the fat from the skillet.

Step 5

Stir the chili powder, salt, oregano, cumin, and cayenne into the beef mixture.

Step 6

In the prepared baking dish, layer 1/2 of the potato slices to cover the bottom. Some overlap is okay.

Step 7

Season the potatoes with salt and pepper, to taste.

Step 8

Top the potatoes with 1/2 of the beef mixture, 1/2 of the beans, and 1/2 of the bacon.

Step 9

Pour 1 can of tomato soup over top of the bacon.

Step 10

Repeat the layers starting with the potatoes.

Step 11

Cover the baking dish with foil and bake for 1 hour.

Step 12

Remove the foil.

Step 13

Sprinkle the top of the casserole with the cheddar and cornflake mixture.

Step 14

Return the casserole to the oven and bake, uncovered, until the cheese is melted, the topping is golden-brown, and the potatoes are tender, for about 10-15 minutes.

Step 15

Garnish with parsley and serve.
