Inspirations

This Crispy Topped Tuna Noodle Casserole is the ultimate comfort food, standing the test of time with its creamy filling and golden, crunchy panko topping. It’s the kind of dish that makes you want to curl up, grab a fork, and let the nostalgia take over. Even better, it’s perfect for those evenings when you want a hearty, satisfying meal without a complicated prep list.

Now, I know tuna casserole might seem old-fashioned—retro, even. You might picture potlucks in church basements, family gatherings where every dish was covered in foil, or maybe even those awkward school lunch moments (yes, cafeteria tuna casserole had its own reputation). Still, despite all that, there’s something about this casserole that always delivers. The creamy center, the melted cheese, and that irresistible crunchy topping all come together to remind you why it became a classic in the first place.

For many of us, tuna casserole is tied to childhood memories. It’s one of those dishes your mom or grandma might have pulled together on a busy weeknight, when convenience and comfort mattered more than trends. Back then, you didn’t care if it was cool or not—you only cared about scooping up that creamy, cheesy goodness before your siblings got to it first. Even today, when food fads come and go, this dish holds its own. In fact, it proves that flavor and comfort never really go out of style.

Let’s be honest, though: tuna casserole has lived in the shadows of quinoa salads, kale bowls, and grain-free everything for a while now. Nevertheless, it deserves a comeback—and this version is my little remix. I stick with canned tuna (because really, that’s the point), then layer in thyme, a touch of Dijon for tang, and a cheese duo of sharp cheddar and Gruyère for comfort plus a nutty, melty lift. Topped with golden, crackly panko, it’s familiar and nostalgic, yet at the same time warm and modern enough to stand proud on today’s table.

And the textures? That’s where everything truly comes together. Creamy sauce wraps around tender noodles, the tuna adds that hearty bite, and then the golden panko topping seals the deal with a crunch that keeps things from getting too soft and sleepy. As a result, it’s one of those dishes that feels both nostalgic and new—like finding your favorite old sweatshirt and realizing it still fits perfectly, but better.

So sure, kale can keep its crown for “health halo” food, and quinoa can keep pretending it’s exciting. Meanwhile, tuna noodle casserole will quietly keep winning hearts one crunchy-topped bite at a time.

Pro Tips and Riffs

No Gruyère? Try Fontina or Monterey Jack. Want more sharpness? Go all cheddar.

Fold in sautéed mushrooms or spinach for a veggie boost without losing the comfort factor.

Assemble earlier in the day, refrigerate, then bake when you’re ready. Just don’t add the panko until right before baking so it stays crisp.

The casserole reheats beautifully. Pop individual squares in the oven or air fryer to crisp up the topping again.

Faq: Grub Answers and Insights

A: Yes, but panko gives a lighter, crunchier topping. Regular breadcrumbs will work, but the texture won’t be quite as airy.

A: Solid white albacore has a firmer texture and mild flavor, while chunk light is softer and more budget-friendly. Either works—go with your preference. I prefer Safe Catch Tuna because it tests each tuna for mercury to guarantee purity

A: Yes. Bake, cool completely, then wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and reheat, uncovered, until warmed through.

A: Don’t overbake—once the center is set and a toothpick comes out clean, pull it. Adding a little extra sour cream also keeps the filling creamy.

Description

Cozy and from-scratch, this tuna noodle casserole bakes tender egg noodles in a light, creamy Dijon-thyme sauce—no canned soup. Two cheeses melt through the pasta while a buttery panko–Gruyère topping turns crisp and golden with a pop of lemon zest. Weeknight-easy, crowd-pleasing comfort food.


Ingredients

Scale

Casserole

6 ounces wide egg noodles (about 2 cups dry noodles)

1 ½ tablespoons unsalted butter

1 tablespoon olive oil

3 large garlic cloves, minced

3 stalks celery, diced

3 tablespoons onion, diced

2 ½ tablespoons flour

1 ½ cup milk (I use skim)

¾ cup low-sodium chicken broth

¾ tablespoon cornstarch

¾ tablespoon Dijon mustard

¾ teaspoon garlic salt

½ teaspoon dried thyme

¼ teaspoon coarse ground pepper

1 cup shredded mixed cheddar cheese

¼ cup shredded Gruyere cheese

¼ cup sour cream

2 cans (5 oz each) of canned tuna

Panko Topping

1 tablespoon unsalted butter

2 tablespoons panko

2 tablespoons shredded Gruyere cheese

½ tablespoon lemon zest


Instructions

  1. Cook the egg noodles in salted water until al dente, about 7-8 minutes. Reserve ½ cup of pasta water for thinning the sauce later, if needed. Drain and set aside.
  2. Meanwhile, melt 1 tablespoon of butter over medium heat in a nonstick skillet. Add panko and stir to coat. Continue cooking until the crumbs become golden brown. In a small bowl, combine Panko breadcrumbs, Parmesan cheese, and lemon zest.  Mix until evenly combined.
  3. Preheat oven to 350 degrees F. Lightly spray an 8x8 pan with nonstick cooking spray.
  4. Melt butter with olive oil in a large skillet or Dutch over medium heat (something that can fit all ingredients). Add the onions and celery, and sauté for 5 minutes.  Add garlic and sauté for 30 seconds or until fragrant.
  5. Push the onion, celery and garlic to the edge of the pan. Whisk in flour and cook, while stirring for 2 minutes (it will be lumpy). Cooking the flour helps to get rid of the raw, starchy flavor. Slowly whisk in milk and ½ cup chicken broth. Whisk cornstarch with remaining ¼ cup chicken broth and add to skillet followed by Dijon, salt, pepper, and thyme.
  6. Bring sauce to a boil, whisking constantly then reduce heat to a simmer, whisking often until thickened. Remove from heat and whisk in ½ cup cheddar and Gruyere cheese until melted. Whisk in sour cream until blended.
  7. Add the tuna and stir until well combined. Gently fold in the noodles until everything is evenly mixed. If the sauce seems too thick, add a bit of the reserved pasta water to loosen it. Transfer the mixture to the prepared baking dish, then sprinkle with ½ cup of cheddar cheese and the panko for extra crunch.
  8. Cover with foil and bake at 350 degrees for 30 minutes, uncover and bake an additional 10-15 minutes or until hot and bubbly and the cheese is melted; serve piping hot. Optionally, broil for 2-3 minutes to brown the crust on top.

Notes

Undercook the noodles by 1–2 minutes; they’ll finish in the oven and stay tender, not mushy.

Season the sauce before adding tuna/noodles. Taste for salt/pepper/Dijon while it’s still in the pan. (Add salt to cheese and tuna quickly—start modestly, adjust as needed.)

Toast the panko in butter, then let it cool for 2–3 minutes before mixing it with Gruyère and lemon zest—this keeps the topping light and crisp.

Fold don’t stir. Add tuna last and gently fold to keep nice flakes. Albacore = bigger chunks; chunk light = milder flavor. Drain well.

Pan size matters: 8×8 or 9×9 = creamier, deeper casserole; 9×13 = thinner layer, bakes quicker. If browning too fast, tent with foil.

Loosen if needed: Reserve ½ cup pasta water; add a splash when mixing if the sauce tightens.

Optional veggies: ½–1 cup peas (thawed), sautéed mushrooms, or blanched broccoli florets fold in beautifully.

Make-ahead: Assemble without the panko topping, cover, and refrigerate up to 24 hours. Add topping just before baking; add 5–10 minutes to bake time.

Reheat: 325°F, covered, 15 minutes; uncover 5 minutes to re-crisp. Add a spoonful of milk or broth to keep it creamy.
