It bakes up bubbly, holds well for leftovers, and reheats like a champ. The simple prep lets you keep dinner calm even when the day feels anything but.
Ingredients You’ll Need
- Egg noodles, 12 ounces (medium width works best; use gluten-free noodles if needed)
- Canned tuna, 10 to 12 ounces total, drained well (albacore for meatier texture, light tuna for milder flavor; oil-packed gives richer flavor)
- Frozen peas, 1 cup (no need to thaw)
- Onion, 1 small, finely chopped
- Celery, 2 ribs, finely chopped
- Mushrooms, 6 ounces, sliced (optional but tasty)
- Butter, 4 tablespoons
- All-purpose flour, 4 tablespoons (use a 1:1 gluten-free flour if needed)
- Low-sodium chicken or vegetable broth, 1.5 cups
- Milk or half-and-half, 1.5 cups (oat milk works for dairy-light; keep it unsweetened)
- Dijon mustard, 1 teaspoon
- Lemon juice, 1 tablespoon
- Sharp cheddar, 1.5 cups shredded (Gruyère or Monterey Jack also work)
- Sour cream, 1/3 cup (adds extra creaminess; skip if you want it lighter)
- Kosher salt and black pepper
- Paprika, a few shakes for color
Shortcut option:
- Swap the butter, flour, broth, milk, and sour cream with 2 cans condensed cream of mushroom soup plus 3/4 cup milk. Campbell’s works, and Pacific Foods condensed soup gives a cleaner label.
Topping:
- Panko breadcrumbs, 1 cup (use gluten-free if needed)
- Parmesan, 1/4 cup grated
- Melted butter or olive oil, 2 tablespoons
- Pinch of salt
Equipment:
- 9 by 13 inch baking dish
- Large pot for noodles
- Large skillet or Dutch oven
- Colander
- Mixing bowl
- Measuring cups and spoons
How to Make Tuna Casserole Recipe
Step 1: Boil noodles and prep
Heat the oven to 375°F and grease a 9 by 13 inch baking dish. Bring a large pot of salted water to a boil and cook noodles 2 minutes shy of al dente. Drain and toss with a little olive oil so they do not stick.
Step 2: Sauté veggies and start the sauce
Melt 4 tablespoons butter in a large skillet over medium heat. Add onion, celery, and mushrooms; cook until soft and lightly golden, 6 to 8 minutes. Stir in flour and cook 1 minute, stirring often, so it tastes toasty, not raw.
Step 3: Finish the sauce and fold in the goodies
Whisk in broth and milk, a splash at a time, until smooth. Simmer 3 to 4 minutes until the sauce visibly thickens and coats a spoon. Stir in Dijon, lemon juice, 1 cup cheddar, sour cream, peas, and tuna; season with 1 teaspoon kosher salt and 1/2 teaspoon black pepper to start.
Shortcut path: In a large bowl, mix condensed soup with 3/4 cup milk, Dijon, lemon, and 1 cup cheddar. Fold in peas and tuna, then season.
Step 4: Combine and assemble
Fold noodles into the sauce until everything looks evenly coated. Transfer to the prepared baking dish and smooth the top. Mix panko, Parmesan, melted butter or oil, and a pinch of salt, then sprinkle over the casserole and dust with paprika.
Step 5: Bake and rest
Bake 18 to 22 minutes until the edges bubble and the top turns golden. If you want deeper color, broil 1 minute, watching closely. Let it rest 10 minutes so the sauce sets, then shower with chopped parsley or chives and serve.
Tips & Tricks
- Salt pasta water like the sea for flavorful noodles.
- Undercook noodles by 2 minutes so they keep a pleasant bite after baking.
- Drain tuna very well to avoid watery sauce.
- Sauce looks tight before baking, so aim for creamy, not pasty; add a splash of milk if it feels too stiff.
- Use oil-packed tuna for richer flavor; use light tuna for a milder taste and softer texture.
- Add a pinch of Old Bay or celery salt if you crave that classic deli vibe.
- Go veggie-forward with 1 cup chopped spinach or small broccoli florets stirred into the sauce.
- For gluten-free, use GF noodles and panko and a 1:1 GF flour in the roux, or use a GF condensed soup.
- For dairy-light, use olive oil instead of butter and an unsweetened plant milk; finish with a dairy-free cheddar.
- Want extra crunch on top? Mix crushed kettle chips with the panko.
What to Serve with Tuna Casserole
This dish loves a crisp green salad with lemon vinaigrette, roasted green beans, or garlicky broccoli. Warm dinner rolls or sourdough make great sauce moppers. Add lemon wedges and hot sauce for bright pops of flavor. For drinks, pour a chilled Pinot Grigio, a pilsner, or sparkling water with a squeeze of citrus.
Make-Ahead and Storage
- Make-ahead: Assemble the casserole through topping, cover, and refrigerate up to 24 hours. Let it sit at room temp 20 minutes, then bake 25 to 30 minutes until hot and golden. If the mix looks thick from chilling, stir in 2 to 4 tablespoons milk before baking.
- Freezer: Assemble without the topping, wrap tight, and freeze up to 2 months. Bake from frozen at 350°F, covered, 40 to 50 minutes, then add the topping and bake 15 minutes more until hot and crisp. You can also thaw overnight and bake 25 to 30 minutes.
- Leftovers: Store in an airtight container in the fridge up to 4 days. Reheat covered at 325°F for 15 to 20 minutes with a small splash of milk, or microwave gently in 60 to 90 second bursts, stirring once. Broil 1 minute to re-crisp the top if you like.
