Why I Like This Recipe
Not gonna lie, I wasn’t in the mood to cook. Dug around, found a can of tuna, leftover pasta, and figured… why not. Dumped it all in a dish, baked it, and wow. Warm, cheesy, crunchy — kinda hit the spot.
Ingredients
- 3 cups cooked macaroni
- 1 (5 oz) can tuna, drained
- 1 (10.5 oz) can condensed cream of chicken soup
- 1 cup shredded cheddar cheese
- 1½ cups French fried onions
How To Make Tuna Casserole
- Preheat oven: 350°F (175°C) — first thing.
- Mix the base: Toss macaroni, tuna, and soup in a 9×13 dish.
- Cheese layer: Sprinkle the cheddar over the top.
- Bake it: 25 mins till bubbly and golden.
- Add crunch: Top with fried onions, bake 5 more mins. Done.

Tips for Success
- Salt your pasta water or the whole thing tastes flat.
- Use sharp cheddar — it cuts through the creaminess.
- Add the onions at the end so they don’t burn.
- Stir everything really well or you’ll get dry pockets.
Storage and Reheating
- Fridge: Lasts 3–4 days sealed up.
- Freezer: Freeze in portions. Reheat from thawed or bake straight from frozen.
- Microwave: 1–2 minutes works fine, cover it.
- Oven: 300°F for 10–15 minutes until hot again.
Frequently Asked Questions
- Q1: Can I use cream of mushroom?
Yep — works great. A little earthier but still solid. - Q2: What kind of tuna?
I usually go with chunk light. Anything canned works if it’s not too wet. - Q3: Can I make it ahead?
Yeah, mix it all, skip the onions, and chill it. Add onions right before baking. - Q4: What else can I toss in?
Frozen peas, corn, even a splash of hot sauce if you’re feeling it. - Q5: Is this kid-friendly?
Totally. Cheesy pasta? Always a win.
Common Mistakes and How to Dodge Them
- Pasta overcooked: Undercook it slightly since it bakes again.
- Burnt onions: Add them at the very end — last 5 minutes max.
- Bland flavor: Use sharp cheese, season the base if needed.
- Skipping the mix: Don’t just layer — stir the tuna, soup, and pasta well.
- Too much liquid: Stick with just one can of soup or it’ll be runny.
