Ingredients

Ready to whip up a comforting tuna casserole? The secret to this classic dish lies in balancing creamy, savory, and crunchy elements. Here’s what you’ll need to nail it:

Egg Noodles: Use wide Egg Noodles—they hold the sauce better than thinner varieties. If you’re out of egg noodles, cavatappi or penne pasta works as a solid substitute.

Canned Tuna: Opt for tuna in water for a lighter dish, but tuna in oil adds richness. Albacore is my go-to for its firm texture and mild flavor.

Cream of Mushroom Soup: This is the backbone of the sauce—don’t skip it! If you’re feeling fancy, swap it with homemade cream of mushroom sauce for an elevated twist.

Cheddar Cheese: Sharp cheddar melts beautifully and adds depth. For a milder flavor, try Monterey Jack or even Swiss cheese.

Milk: Whole Milk gives the sauce a luxurious creaminess, but 2% will do in a pinch. Avoid skim milk—it can make the sauce too thin.

Breadcrumbs: Panko Breadcrumbs are a game-changer for that perfect golden crust. If you don’t have breadcrumbs, crushed crackers or cornflakes make a great alternative.

Peas: Frozen Peas add a pop of color and sweetness. Feel free to substitute with broccoli or carrots if you prefer.

Onion: A finely diced Onion adds savory depth. If you’re short on time, onion powder works in a pinch.

Garlic: Freshly minced Garlic is a must for that aromatic punch—garlic powder just doesn’t compare.

Little Wins: Sprinkle a bit of Parmesan cheese on top before baking for an extra layer of flavor, and garnish with fresh parsley for a restaurant-worthy finish.

How to Make the Best Classic Tuna Casserole Instructions

Flexibility: Transfer the mixture to the prepared baking dish and sprinkle with 1 cup of shredded cheddar cheese.

For extra crunch, add a topping of crushed potato chips or breadcrumbs.

Pro Tips Included: Bake uncovered for 20-25 minutes, or until the top is golden and bubbly.

Let it rest for 5 minutes before serving to allow the flavors to meld and the casserole to set.

Time-Saving Tricks: If you’re in a hurry, use canned peas instead of frozen or pre-shredded cheese to skip prep steps.

Serve hot and enjoy!

Chef Tips

While understanding the nutritional breakdown is helpful, I’ve found that a few simple adjustments can elevate the flavor and texture of this tuna casserole.

Toast the breadcrumbs for extra crunch, use fresh herbs like parsley or dill, and mix in a splash of lemon juice to brighten the dish.

Don’t overcook the pasta—al dente holds up better. A touch of Dijon mustard adds depth without overpowering.
