  • 1 teaspoon chili powder
  • 1/2 teaspoon salt
  • Dash pepper

  • 2 cups (8 ounces) shredded sharp cheddar cheese

Steps to Make It

  1. Gather the ingredients.

  2. Grease a 9 x 13 x 2-inch baking pan (2 1/2- to 3-quart size).

  3. Heat oven to 350 F.

  4. Heat the olive oil in a large skillet over medium heat.

  5. When the oil is hot and shimmering, add the ground beef, onions, and celery.

  6. Cook until beef is browned and vegetables are tender, stirring frequently.

  7. Add garlic and peppers; cook, for about 1 minute longer, stirring frequently.

  8. Stir in the tomatoes, chili powder, salt, pepper, and cumin. Bring to a simmer.

  9. In the prepared baking dish, arrange half of the sliced potatoes, then top with half of the corn, half of the ground beef mixture, and half of the cheese.

  10. Repeat the layers, ending with the remaining cheese.

  11. Cover the baking dish tightly with foil and bake for about 1 hour and 15 minutes, or until potatoes are tender.

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.
