1/4 cup all-purpose flour
2 1/2 cups whole milk
1 cup low-sodium chicken broth
1 teaspoon salt

Instructions
Preheat the oven to 350°F (175°C). Lightly grease a 9×13 inch casserole dish.
Cook the egg noodles in a large pot of boiling salted water according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the sliced mushrooms and cook until they release their moisture and begin to brown, about 6-7 minutes.
Add the chopped onion and cook until softened, about 4 minutes. Stir in the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the mushroom mixture and stir constantly for 2 minutes to cook the flour.
Gradually whisk in the milk and chicken broth, continuing to stir until the sauce thickens, about 5 minutes.
Season the sauce with salt, black pepper, and dried thyme. Remove from heat.
Stir in the thawed peas, flaked tuna, and shredded cheddar cheese until evenly combined.
Add the cooked egg noodles to the sauce mixture and gently fold to combine.
Transfer the mixture to the prepared casserole dish and spread evenly.
In a small bowl, toss the breadcrumbs with olive oil until evenly coated. Sprinkle the breadcrumb mixture evenly over the casserole.
Bake uncovered in the preheated oven for 25 minutes, or until the top is golden brown and the casserole is bubbly.
Remove from the oven and let rest for 5 minutes before serving.

Classic Tuna Casserole: Ingredient Hacks, Why It Works, and Rescue Tips
The Noodle Game: Why Egg Noodles Aren’t the Only Players
Egg noodles soak up that rich mushroom sauce like a champ, but let’s face it—sometimes pantry staples play hard to get. No egg noodles? Don’t sweat it. Rotini or penne? Perfect substitutes. They hold sauce in all the right nooks and crannies, keeping every bite juicy. Want a gluten-free twist? Rice noodles or even spiralized zucchini work wonders—though they bring a different vibe to the party. Pro tip: if you swap in anything that’s not egg noodles, cut cooking time by a minute or two to keep that al dente snap. Trust me, soggy pasta is the enemy here. Also, frozen peas are the MVP for that subtle sweetness and pop of color. Fresh peas? Awesome, but toss them in at the last minute of sauce simmering to keep their snap. Mushrooms are the umami backbone—if you want to jazz it up, shiitakes or creminis bring deeper earth tones. But don’t go overboard; this isn’t a mushroom festival.
Why the Sauce Is Your Secret Weapon—And How to Nail It Every Time
Butter melts — mushrooms sizzle — onions soften — garlic sings. That’s your flavor base, right there. Then comes the roux: flour sprinkles in, stirring nonstop to avoid that nasty raw taste. Whisking in milk and chicken broth gradually thickens the sauce like magic, but here’s the kicker: keep stirring. No stirring, no thickening, just lumps lurking like little saboteurs. Season early—salt, black pepper, thyme. It breaks down and infuses while the sauce bubbles up, making every spoonful sing. Adding cheese at the end? It’s the glue, the flavor punch, and the gooey dream all in one. But toss cheese too early, and you’ll have a curdled mess on your hands. Been there, done that—it’s a rookie move. Your sauce should coat the noodles smoothly, not drown ’em. That balance? It’s the difference between a sloppy casserole and a dish you’ll crave on a rainy day.
Breadcrumb Topping Troubles? Here’s How to Bring the Crunch Back to Life
Listen, soggy breadcrumbs are the bane of tuna casserole lovers everywhere. You cook that golden crust only to have it turn limp and sad? No bueno. The trick is in the drizzle – olive oil coats the crumbs before they hit the casserole, creating that crisp fortress we all crave. If you forgot the drizzle and your topping’s turned mushy, pop the casserole under the broiler for 2-3 minutes—watch it like a hawk or it’ll go from crunch to coal in a heartbeat. Another move? Mix in a handful of grated Parmesan with your breadcrumbs for extra crisp and a nutty edge. Some folks swear by panko, which is flashier but less forgiving if you overbake. Also, if you’re reheating leftovers and the topping’s lost its mojo, hit it with a quick toaster oven blast. Crispy magic restored, no sweat. It’s all about respecting that crunch game; without it, your casserole’s just mush in a pan.
Classic Tuna Casserole FAQ
A: Absolutely! Swap tuna with canned salmon for a twist. It’ll change the vibe but keep that creamy, comforting feel intact.
A: Yes, you can skip them. Mushrooms bring earthiness, but if you’re not a fan or don’t have any on hand, the casserole will still taste great—just a bit lighter.
A: For sure. Assemble it, cover it tight, and stash it in the fridge for up to 24 hours before baking. Just add a few more minutes in the oven if it’s cold from the fridge.
A: Toss breadcrumbs in olive oil (or melted butter if you want to live dangerously) before sprinkling on top—that’s the secret sauce for golden, crispy goodness. It’s the crunch that brings the whole dish alive.
A: Yes, definitely. Freeze in a sealed container for up to 2 months. Thaw overnight in the fridge—don’t rush it, patience is key here—then reheat until bubbly.
