Ingredients

  • 2 tablespoons cooking oil
  • 1 onion, chopped
  • 1 pound ground beef
  • 1 (19 ounce) can kidney beans with liquid
  • 1 (19 ounce) can pineapple chunks with juice
  • 1 cup ketchup

Method

  • Preheat an oven to 350 degrees F (175 degrees C).
  • Heat the oil in a skillet over medium heat; cook the onion in the hot oil until softened, about 5 minutes. Crumble the ground beef into the skillet and cook and stir until completely browned, 5 to 7 minutes. Drain.
  • Stir the kidney beans with liquid, pineapple with juice, ketchup, brown sugar, cornstarch, mustard, and salt together in a large bowl. Add the ground beef and onions to the mixture and stir to coat. Pour into a large casserole dish.
  • Bake in the preheated oven until completely heated through, about 45 minutes.
