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!

Great recipe! I halved it too but still used 2 cans of tuna, and used multi-whole-grain macaroni instead of regular. I also added onion powder, 1.5 cups frozen peas & 1.5 cups frozen broccoli to beef it up. Topped it with crumbled wheat toast mixed with the extra cheese. All-in-one meal, and tons of leftovers! Will save this one, thank you.

We really enjoyed this. Like another reviewer, I halved the recipe, but used 2 cans of tuna. The other change was that I added frozen peas when we mixed everything together at the end. It really hit the spot!!!
