Instructions

Classic Tuna Casserole Recipe

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). This ensures your casserole bakes evenly. While the oven heats, grease your 9×13 inch baking dish with a bit of butter or cooking spray to prevent sticking.

Step 2: Cook the Macaroni

Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente, usually about 8 minutes. Drain well and return to the pot. Tip: Rinsing the pasta under cold water stops the cooking process and prevents it from becoming mushy.

Step 3: Mix the Ingredients

In the pot with the drained macaroni, stir in the condensed cream of mushroom soup, milk, shredded cheddar cheese, drained tuna, and frozen peas. Mix until everything is well combined. Season with salt and pepper to taste. Tip: For extra flavor, consider adding a teaspoon of garlic powder or onion powder.

Step 4: Transfer to Baking Dish

Pour the mixture into the prepared baking dish, spreading it out evenly. In a small bowl, mix the breadcrumbs with the melted butter, then sprinkle over the top of the casserole. This will give your dish a deliciously crispy topping.

Step 5: Bake to Perfection

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbly around the edges. Let it sit for 5 minutes before serving to allow it to set. Tip: For an extra crispy top, broil for the last 2-3 minutes of baking.

Tips and Tricks

For those looking to elevate their classic tuna casserole, here are some advanced tips. First, consider making your own cream of mushroom soup from scratch for a richer flavor. Second, add a layer of sliced mushrooms or onions for extra texture and taste. Third, experiment with different types of cheese, such as Gruyère or Parmesan, for a more sophisticated flavor profile. Lastly, for a healthier version, use whole wheat pasta and low-fat milk.

Recipe Variations

  • Swap the tuna for cooked chicken or salmon for a different protein option.
  • Add in different vegetables like broccoli, carrots, or bell peppers for added nutrition and color.
  • Use a different type of pasta, such as penne or shells, for a new texture.
  • For a spicy kick, mix in some diced jalapeños or a dash of hot sauce.
  • Top with crushed potato chips or crackers instead of breadcrumbs for a different crunch.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! You can assemble the casserole up to a day in advance and keep it covered in the refrigerator. When you’re ready to bake, you may need to add a few extra minutes to the baking time since it will be cold from the fridge.

Can I freeze tuna casserole?

Yes, tuna casserole freezes well. Bake it as directed, let it cool completely, then cover tightly with foil and freeze. To reheat, thaw in the refrigerator overnight and bake at 350°F until heated through, about 30 minutes.

What can I use instead of cream of mushroom soup?

If you’re not a fan of cream of mushroom soup, you can use cream of chicken or celery soup instead. Alternatively, you can make a homemade white sauce as a substitute.
