Smart Swaps to Keep Costs Low
- No egg noodles? Use whatever pasta is in the pantry — rotini, penne, or elbow macaroni all work.
- No cream of mushroom? Cream of celery or cream of chicken soup works just as well.
- No frozen peas? Canned corn or mixed vegetables are great substitutes.
- Cheese on sale? Stock up. Shredded cheese freezes beautifully.

No fancy equipment needed. No culinary degree required. Just a pot, a baking dish, and about 10 minutes of actual effort.
Step 1: Preheat and Prep
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a tiny bit of butter.
Step 2: Cook the Noodles
Boil the egg noodles in salted water until just al dente — about 1–2 minutes less than the package says. Spoiler alert: they'll keep cooking in the oven, so don't go past al dente or they'll turn mushy.
Step 3: Mix the Filling
In a large bowl, combine:
- Drained canned tuna
- Cream of mushroom soup
- Milk
- Frozen peas (no need to thaw)
- Half the shredded cheese
- Salt, pepper, and garlic powder to taste
Stir until everything is evenly coated. Fold in the cooked noodles gently.
Step 4: Assemble and Top
Pour the mixture into the prepared baking dish. Spread it out evenly. Top with the remaining shredded cheese, then sprinkle breadcrumbs over everything. Fair warning: the breadcrumb layer is what makes this casserole chef's kiss — don't skip it.
Step 5: Bake
Bake uncovered for 25–30 minutes, until the top is golden and the edges are bubbling. Let it rest for 5 minutes before serving — this helps it set so it scoops cleanly.
Tips to Make Your Cheap Tuna Noodle Casserole Under $10 Even Better
Low effort, high reward — that's the whole vibe here. A few small upgrades make a big difference without adding much to the cost.
Flavor Boosters (All Budget-Friendly)
- Add a squeeze of lemon juice to the filling — it brightens everything up instantly.
- Mix in a spoonful of Dijon mustard for subtle depth. Trust me on this one.
- Sauté half a diced onion in a little butter before mixing — totally optional but absolutely worth it.
- Season generously. Canned ingredients can taste flat; salt and pepper are your best tools.
Make-Ahead & Storage Tips
Future you will thank you for making this ahead. Here's how:
- Make ahead: Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Add 5–10 extra minutes to the bake time if going straight from fridge to oven.
- Leftovers: Store covered in the fridge for up to 3 days. Reheat individual portions in the microwave with a splash of milk to keep it creamy.
- Freezer-friendly: Freeze before baking for up to 2 months. Thaw overnight in the fridge before baking.
Crowd-Pleaser Alert 🙌
