This is a fairly easy little dish that cooks up nicely and doesn't take that much prep work if other than chopping up some onion and celery. I have been told that sauteing the onion and celery first in some butter until tender, greatly improves the recipe, but I have yet to try it myself.


  • 24 oz canned tuna, drained
  • 1 cup celery, chopped
  • 1 cup cheddar cheese, shredded
  • 1 cup onion, chopped
  • 1/2 cup sour cream
  • 1/2 cup mayo
  • 1/4 cup Parmesan cheese, grated
  • 2 TBLS Parmesan cheese, grated, reserved
  • 1/4 cup cheddar cheese, shredded, reserved


  • Preheat oven to 400 degrees
  • Mix all but the reserve ingredients together in a mixing bowl
  • Transfer mixture into a 8 x 8 casserole dish and top with reserve cheeses
  • Bake at 400 degrees for 30 to 40 minutes
