4 Ingredients
1. Egg noodles - are my go to but here are some other noodle options like elbow pasta, fusilli pasta, and rotini will work for this dish.
2. Canned Cream of Mushroom – This adds a rich, creamy, and savory flavor. For the best results, use condensed cream.
Other great alternatives include:
- Condensed cream of chicken
- Condensed cream of celery
- Milk (for a lighter option)
3. Canned Tuna – canned albacore tuna has a mild flavor and firm texture, but any canned tuna will work. Take your pick between canned tuna in water or oil is.

- Monterey Jack
- Colby Jack
- Swiss
- Gouda
- Pepper Jack

Frequently Asked Questions
The casserole may not have enough moisture from the soup or cheese. Using extra condensed soup or adding a splash of milk can help. Also, avoid overbaking, as this can dry it out.
For this 4 ingredient recipe, baking it uncovered allows the cheesy top to crisp up and get golden brown.
This depends on personal taste and dietary preference:
For a richer flavor and extra fat, use tuna in oil. It adds more depth and a silky texture to the casserole.
For a lighter option, use canned tuna in water to reduce fat while still keeping the dish flavorful.
How to store
Keep leftovers in an airtight container for up to 3 days.
