Ingredients for tuna casserole recipe egg noodles cream of mushroom soup
Six pantry staples plus a few fresh touches for that perfect creamy, comforting casserole.
| Ingredient | Amount | Notes |
|---|---|---|
| Egg Noodles 🍝 | 2 cups | Uncooked, medium width |
| Canned Tuna 🐟 | 2 cans | Flaked, in water or oil |
| Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Green Onions 🧅 | ¼ cup | Sliced, white and green parts |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Medium sharp cheddar |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For extra depth |
| Dried Parsley 🌿 | 1 tbsp | For garnish |
| Mayonnaise 🍳 | ¼ cup | For extra creaminess |
The cream of mushroom soup is the heart of this dish—Campbell’s or Healthy Request are my go-tos, but any good-quality brand works. The egg noodles should be medium width (about 1/8-inch) so they hold up during baking without turning mushy. For the tuna, flaked in water gives a cleaner flavor, but oil works too if you prefer richness. I always grab extra cheddar cheese—it melts beautifully and adds that classic casserole texture. The green onions add a fresh pop, so don’t skip the white parts—they’ve got flavor too!
No cream of mushroom soup? Homemade mushroom sauce (sautéed mushrooms, flour, milk) works perfectly—just simmer until thickened. No mayo? A splash of milk or extra butter keeps it creamy. The garlic powder is non-negotiable for depth, but if you’ve got fresh garlic, 1 clove minced would be even better. For the cheese, pre-shredded gets clumpy, so grate your own from a block if you can. The flour is key for thickening—don’t skip it, or the sauce will be too thin. And trust me, fresh parsley at the end makes all the difference!
This casserole tastes even better the next day—double the batch if you can. Store leftovers covered in the fridge for up to 4 days, or freeze portions for 3 months. The cheese gets crispy on top when reheated, so broil for 2-3 minutes if you want that extra crunch. I always make a big tray—half for dinner, half for lunches the next week. The noodles soften further when reheated, so add a splash of milk or water if needed to loosen things up.
Why You'll Love This Recipe
- Pantry Magic: I swear by this recipe when I’m staring into my fridge at 6:30 PM with nothing but a can of tuna and a half-empty carton of milk. Open the can, dump in the soup, stir—it’s that simple. No chopping, no measuring cups, just pure convenience.
- Creamy Mushroom Magic: That creamy mushroom soup base? It’s the secret weapon. The umami from the mushrooms and the richness of the milk make this taste like a restaurant dish, not a weeknight hack. My kids still ask for it even when I make fancy meals.
- Leftovers That Don’t Suck: Honestly, this is one of the few casseroles that actually tastes better the next day. The noodles soften just enough to soak up all the flavor, and the tuna stays tender. I make a double batch on Sundays—lunches are covered for the week.
- Budget-Friendly Feast: For under $10, I feed four people a meal that feels special. Canned tuna, egg noodles, and a jar of soup stretch into something hearty, and the butter adds that little touch of indulgence without breaking the bank. My wallet thanks me.
Step-by-step instructions for creamy mushroom tuna casserole
Here's how to create that perfect creamy, comforting dish with minimal fuss.
🍳 Step 1: Cook the Egg Noodles Al Dente
Bring a large pot of salted water to a rolling boil. Add the 2 cups egg noodles and cook according to package instructions for 1 minute less than recommended. You want them al dente—they'll finish cooking in the oven. Drain and set aside, reserving ½ cup pasta water in case the sauce needs thinning later.
I always taste-test the noodles before draining—they should have a slight bite but be fully cooked through. This ensures they don't turn mushy when baked later. Don't rinse them; the starch helps thicken the sauce and creates that creamy texture we're after.
🥘 Step 2: Build the Creamy Sauce Base
In a large oven-safe skillet or casserole dish, melt the 0.5 cup butter over medium heat. Stir in the 2 tbsp all-purpose flour and cook for 1-2 minutes until bubbly but not browned. This creates our roux foundation.
Slowly whisk in the 0.5 cup milk and 0.25 cup mayonnaise until smooth. Add the 2 cans cream of mushroom soup, stirring until fully combined. The mixture should thicken slightly as it heats—if it gets too thick, add a splash of reserved pasta water to maintain that perfect creamy consistency.
👨🍳 Step 3: Combine All Ingredients
Add the drained egg noodles to the skillet and stir gently to coat evenly. Fold in the 2 cans flaked tuna, 0.25 cup sliced green onions, 0.5 tsp garlic powder, 0.5 tsp black pepper, and 1 tsp salt. Mix everything together carefully so the noodles don't break apart.
Here's where the magic happens: sprinkle the 1.5 cups shredded cheddar cheese evenly over the top. The cheese will melt beautifully during baking, creating that rich, gooey layer we all love. I like to press down gently on the cheese to help it melt more thoroughly.
🔥 Step 4: Bake to Golden Perfection
Transfer the skillet to a 375°F preheated oven and bake uncovered for 20-25 minutes until the top is golden brown and bubbly. The edges should be slightly crispy while the center remains creamy.
I know it's tempting to peek, but resist! Every time you open the oven, you lose heat and moisture. The cheese should be fully melted with just a few brown spots on top—that's your signal it's ready. If the top browns too quickly, tent it loosely with foil for the last 5 minutes of baking.
🍽️ Step 5: Rest and Garnish
Remove from the oven and let the casserole rest for 5 minutes before serving. This resting period allows the cheese to set slightly and the flavors to meld together. Sprinkle with 1 tbsp dried parsley right before serving for that fresh pop of color and flavor.
Serve immediately with a side of steamed green beans or a simple garden salad. The creamy mushroom sauce should coat every bite of noodle perfectly, with tender tuna and melty cheese in every forkful. Leftovers taste even better the next day—just reheat gently to maintain that creamy texture!
Pro Tips For Making Tuna Casserole Recipe Egg Noodles Cream Of Mushroom Soup
- Drain Noodles Well: I learned this the hard way—soggy noodles ruin the texture. Rinse them under cold water, then drain in a colander for a full minute before adding to the casserole. The extra effort keeps the dish from turning into a mushy, waterlogged mess, especially if you’re using fresh or thicker egg noodles.
- Mix Tuna Last: Adding the drained tuna right before baking keeps it from absorbing too much moisture and turning into a sad, watery clump. Fold it in just as you transfer the casserole to the oven—this way, it stays flaky and warm, not a sad, rehydrated brick.
- Butter the Dish First: A thin layer of melted butter on the baking dish (about 1 tablespoon) prevents the casserole from sticking and adds a subtle richness. This is non-negotiable if you’re using a nonstick pan but still want that golden, crispy edge—especially if you’re skipping breadcrumbs.
- Use Whole Milk, Not Light: Whole milk makes a real difference in this dish—it adds creaminess without making the casserole feel heavy. Light or skim milk can turn the sauce thin and watery, especially when combined with the soup. Trust me, the extra 2% fat is worth it.
Serving suggestions for this dish
Classic Side Pairings
Steamed green beans with a squeeze of lemon brighten the richness of the casserole beautifully. I like to toss them with 1 tbsp butter and ½ tsp garlic powder while still hot—just enough to keep them tender-crisp.
For a heartier option, serve with a simple garden salad with a light vinaigrette (2 tbsp olive oil, 1 tbsp red wine vinegar, pinch of salt). The crisp vegetables cut through the creamy texture perfectly. 🥗
Crunchy Contrast Toppings
Add a garnish of toasted breadcrumbs or crushed potato chips on top before serving for extra texture. For a homemade version, mix ¼ cup panko with 1 tbsp melted butter and toast in a dry skillet for 2-3 minutes until golden.
Sprinkle over the hot casserole just before serving—it adds a delightful crunch that contrasts the creamy sauce. 🌟
Beverage Pairings
A crisp white wine like Sauvignon Blanc or a light lager balances the dish's richness. I often reach for a chilled Pinot Grigio from Italy—its citrus notes complement the mushroom sauce beautifully.
For non-alcoholic options, try sparkling water with a splash of lemon or iced tea with a mint garnish. The effervescence helps cleanse the palate between bites. 🍷
Make-Ahead Serving Tips
This casserole tastes even better the next day, so double the batch and store leftovers in an airtight container in the fridge for up to 4 days. Reheat covered in the microwave for 2-3 minutes on medium power, stirring halfway.
For a crispier top, transfer to a baking dish and broil for 2-3 minutes until bubbly. Serve with a side of buttered dinner rolls to soak up any extra sauce. ⏰
Family-Friendly Additions
Kids love the cheesy goodness, but you can make it even more appealing with fun garnishes. Try adding diced bell peppers or cherry tomatoes for color and crunch. For picky eaters, serve with a side of apple slices or carrot sticks—the sweetness balances the savory casserole.
I often let my kids sprinkle their own extra cheese on top before baking. 💛
Presentation Tricks
For a restaurant-worthy look, serve the casserole in a preheated cast-iron skillet straight from the oven. Garnish with fresh green onions and parsley arranged in a circular pattern. If using a baking dish, transfer to a serving platter and add a drizzle of homemade mushroom gravy for extra elegance.
Warm dinner rolls on the side complete the presentation. ✨

Frequently asked questions
Can I make this tuna casserole without cream of mushroom soup?
You can substitute with 1 cup homemade mushroom sauce (sauté ½ cup sliced mushrooms in 1 tbsp butter, add 1 tbsp flour, then whisk in 1 cup milk and simmer until thickened). Or use 1½ cups chicken broth mixed with 2 tbsp cornstarch and 1 tbsp butter for a lighter version. The key is achieving that creamy, savory base.
Why does my casserole end up watery?
Watery casseroles usually happen from one of three things: overcooked noodles (don't rinse them—starch helps thicken the sauce), not enough thickening agent (add 1 tbsp cornstarch to the sauce if needed), or too much liquid. Always cook noodles 1 minute less than package instructions and let the sauce reduce slightly before adding cheese. The cheese will melt and help bind everything together.
Can I use frozen egg noodles instead of fresh?
Yes, but with one important adjustment: thaw them first according to package instructions, then drain and pat dry thoroughly. Frozen noodles release more moisture when cooked, which can make your casserole soggy. For best results, spread them on a baking sheet while thawing to prevent clumping. They'll absorb the sauce just like fresh noodles once baked.
How do I make this vegetarian?
Swap the tuna for 1½ cups cooked chickpeas or 1 cup crumbled firm tofu (pressed and pan-fried for texture). For extra protein, add ½ cup cooked lentils or 1 cup shredded chicken if you're okay with poultry. The umami from mushrooms and cheese will still shine through—just increase the cheese to 2 cups for that classic casserole richness.
Can I bake this in a different-sized dish?
Yes, but adjust baking time accordingly. For a 9x13-inch dish, bake 15-20 minutes (cover with foil if browning too quickly). In an 8-inch round skillet, bake 25-30 minutes**—the smaller surface area means slower cooking. Always check for doneness when the top is golden and center is bubbly. The key is maintaining that creamy texture without drying out the noodles.
