“This is a cheesy tuna casserole recipe that makes enough for 2 casseroles. I sometimes like to make this on a Sunday and have the second casserole for Tuesday. One less day to cook!”

Ingredients Nutrition


  1. Preheat over to 350 degrees.
  2. Melt butter in sauce pan over medium heat. Cook onion for a few minutes and whisk in flour. Cook for a few minutes.
  3. Gradually whisk in milk until smooth, whisking often. Cook for about 15 minutes or until thickened.
  4. Turn off heat and add salt, pepper, oregano, garlic powder, hot pepper flakes, 2 cups of cheddar and 1/2 cup of parmesan.
  5. Meanwhile cook penne or rotini noodles until cooked. Don't overcook as they cook more while baking. Rinse with cold water and return to pot.
  6. Add sauce and tuna to the noodles (it looks like it will be too saucy but it turns out great) and divide between 2 greased 2 liter baking dishes. Top with remaining 1 cup cheddar and 1/2 cup parmesan cheese.
  7. Cover with foil and bake in 350 degree oven for 20 minutes. Uncover and bake for 25 minutes. Yum yum!
