Ingredient Highlights & Notes
The beauty of tuna noodle casserole lies in its simplicity—each ingredient plays an important role in creating that perfect balance of creamy, savory, and satisfying. I always use wide egg noodles because they hold the sauce so beautifully, and good-quality tuna makes a noticeable difference in flavor. The combination of cream of mushroom soup and sour cream creates that signature rich, velvety texture that makes this dish so irresistible.
Ingredients
For the casserole:
- 12 oz wide egg noodles (no-yolk noodles work great too)
- 2 cans (5 oz each) tuna in water, drained (solid white albacore has the best texture)
- 1 can (10.5 oz) cream of mushroom soup (or cream of celery for variety)
- 1 cup sour cream (Greek yogurt works as a lighter substitute)
- 1 cup frozen peas (or mixed vegetables)
- ½ cup diced carrots (adds lovely color and crunch)
- 2 cups shredded cheddar cheese, divided (sharp cheddar gives the best flavor)
- ½ cup milk (whole milk creates the creamiest texture)
- 1 small onion, finely diced (sweet onions are my favorite)
- 2 cloves garlic, minced (fresh is always best)
- Salt and pepper to taste
For the topping:
- 1 cup panko breadcrumbs (creates the crispiest top)
- 3 tablespoons butter, melted
- ¼ cup grated Parmesan cheese (optional but so good)
- 1 teaspoon dried herbs (thyme or oregano work beautifully)
Equipment & Tools
- Large pot for boiling noodles
- 9×13 inch baking dish
- Large mixing bowl
- Medium skillet
- Colander for draining
- Measuring cups and spoons
Instructions & Method
1. Prep your oven and noodles (15 minutes)
Preheat your oven to 350°F and grease a 9×13 inch baking dish. Bring a large pot of salted water to boil and cook the egg noodles according to package directions until just al dente—they’ll finish cooking in the oven. Drain and set aside.
2. Sauté the aromatics (5 minutes)
In a medium skillet, sauté the diced onion until softened and fragrant, about 3-4 minutes. Add the minced garlic and cook for another minute until you can smell that amazing garlic aroma. This step builds so much flavor!
3. Create the creamy base (5 minutes)
In your large mixing bowl, combine the cream of mushroom soup, sour cream, milk, and 1½ cups of the shredded cheese. Whisk until smooth and creamy. The mixture should coat the back of a spoon beautifully.
4. Bring it all together (5 minutes)
Add the cooked noodles, drained tuna (flaked into bite-sized pieces), sautéed onion and garlic, peas, and carrots to the creamy mixture. Gently fold everything together until every noodle is coated in that luscious sauce. Season with salt and pepper to taste.
5. Assemble and top (3 minutes)
Transfer the mixture to your prepared baking dish and spread evenly. Sprinkle the remaining ½ cup of cheese on top. In a small bowl, mix the panko breadcrumbs with melted butter, Parmesan, and herbs, then scatter over the cheese layer.
6. Bake to golden perfection (25-30 minutes)
Bake for 25-30 minutes until the top is golden brown and the edges are bubbling. Let it rest for 5 minutes before serving—this helps everything set up perfectly and prevents burns from that molten cheese!
Tips, Variations & Substitutions
Protein swaps: Try canned salmon, cooked chicken, or even leftover beef from stir-fry for different flavor profiles. The tuna patties recipe on my site uses similar flavors if you want to explore more tuna dishes!
Cheese variations: Mix sharp cheddar with Gruyère for sophistication, or use pepper jack for a spicy kick. Cream cheese can replace some of the sour cream for extra richness.
Vegetable additions: Mushrooms, bell peppers, or broccoli work wonderfully. Sauté harder vegetables first to ensure they’re tender.
Herb magic: Fresh dill, parsley, or chives stirred in at the end add brightness and color.
Troubleshooting: If your casserole seems dry, add a splash more milk. If it’s too wet, bake uncovered for an extra 10 minutes to evaporate excess moisture.
Serving Suggestions
This hearty casserole pairs beautifully with a crisp green salad dressed with lemon vinaigrette to cut through the richness. Steamed broccoli or green beans make excellent vegetable sides, and warm dinner rolls are perfect for soaking up any extra sauce on the plate.
For beverages, a crisp white wine like Sauvignon Blanc complements the creamy flavors wonderfully, while kids (and adults!) love it with cold milk or sparkling water with lemon.
Storage, Make-Ahead & Reheating
Refrigerator storage: Covered tightly, this casserole keeps for up to 4 days in the fridge. The flavors actually meld and improve after a day!
Freezer friendly: Freeze the assembled (but unbaked) casserole for up to 3 months. Thaw overnight in the refrigerator before baking, adding 10-15 extra minutes to the baking time.
Make-ahead magic: Assemble the entire casserole up to 24 hours ahead, cover tightly, and refrigerate. Add the breadcrumb topping just before baking for the crispiest results.
Reheating perfection: Cover with foil and reheat at 325°F until warmed through, about 20 minutes. For individual portions, the microwave works great—just cover and heat in 30-second intervals.

Frequently Asked Questions
Q: Can I use fresh tuna instead of canned?
A: Absolutely! Cook about 1 pound of fresh tuna steaks and flake them into chunks. The flavor will be even more amazing, though canned tuna is perfectly delicious and much more budget-friendly.
Q: What if I don’t like mushroom soup?
A: Cream of celery soup works beautifully, or you can make a simple white sauce with butter, flour, and milk. Cream of chicken soup is another tasty option.
Q: Can I make this gluten-free?
A: Yes! Use gluten-free pasta and either make your own cream sauce or find a gluten-free cream soup. Check that your breadcrumbs are gluten-free too, or use crushed gluten-free crackers.
Q: Why did my casserole turn out watery?
A: Make sure to drain the tuna really well, and don’t overcook the noodles initially. If using frozen vegetables, thaw and drain them first to remove excess moisture.
Q: Can I add more vegetables?
A: Definitely! Just keep the total amount of add-ins reasonable so the casserole doesn’t become too crowded. Sauté any hard vegetables like bell peppers or mushrooms first.
