4 Ingredient Tuna Casserole with Egg Noodles

Photos by Marie-Catherine Dubé

If your fridge is starting to look bare but you’re not quite ready for a grocery store run, this easy tuna casserole is one of my favorite recipes to make when ingredients are low.

This easy meal gets down to basics. The casserole is a mix of creamy mushroom soup, tender egg noodles, and a can of tuna. Add a sprinkle of crispy panko topping and bake for 30 minutes. Voila! Classic comfort food, made simple and delicious.

I love this one for babies and kids because there’s no sour cream or whole milk making it fairly gentle on their stomachs. Too much dairy and fat in one dish can be hard on developing digestive systems. This casserole is the perfect balance of creamy and light. 

For another easy dinner, try Cheesy Mashed Potato Chicken Casserole or 3 Ingredient Meatloaf.

🪄 Tips and Tricks

  • This is a great one for baby led weaning. Set aside a few cooked egg noodles to serve to babies just starting BLW. For the more advanced eaters and toddlers, serve the meal as is or cut the noodles into smaller pieces.


🗒 Substitutions

  • Add extra veggies like: green peas, green beans, diced yellow onion.
  • Add parmesan cheese or sharp cheddar cheese prior to baking.
  • Use rotini pasta or any other thicker noodle.
  • Add green onions or parmesan cheese prior to serving.

Store leftover tuna casserole in an airtight container in the fridge for up the three days. Add a little milk if it seems like it’s dried out in the fridge.

🤔 Common Questions

Is this gluten-free?

This is not gluten-free as written. To make gluten-free you need gluten-free noodles, breadcrumbs and a gluten-free cream of mushroom soup.

Is this recipe dairy-free?

There is dairy in the cream of mushroom soup. To make this dairy-free you need to sub out for a dairy-free version or make your own.

Can I use a different noodle?

Absolutely, I suggest using a thicker noodle, as the pasta is 1/4 of the recipe. Pappardelle, tagliatelle or rotini are great options.
