  5. Mix in the drained diced tomatoes and let the mixture simmer for another 5 minutes. Taste and adjust seasoning if needed.
  6. Transfer the beef mixture into a greased 9×13 inch baking dish.
  7. Evenly spread the sour cream over the top, then sprinkle with shredded cheddar cheese.
  8. Garnish with sliced jalapeños if you like a bit of heat.
