Make-Ahead Method

1-2 days ahead:

  • Tuna Noodle Casserole can be made 1-2 days ahead of time and stored in the fridge until ready to bake.
  • If baking from a cold state, add 15 additional minutes of covered baking time. 

1-3 months ahead:

  • Let it defrost in the fridge for up to 24 hours prior to baking or bake from frozen and add 1 hour to covered baking time.

Topping Options

  • Crushed Ritz Crackers, Crispy Fried Onions, Breadcrumbs, and Potato Chips all make great topping options for tuna noodle casserole.

Pro Tips

  • Half and Half is made of half milk, half cream. You can also use evaporated milk.
  • Frozen carrots, corn, and green beans may also be added.
  • Sliced mushrooms can also be used and sautéed with the onions and celery.
  • For best results, shred the cheese from a block instead of using bagged shredded cheese, which contains cellulose and doesn’t melt as well.
  • My homemade Condensed Cream of Mushroom Soup or cream of chicken soup can also be used instead of a can.
  • 2 cups of leftover chicken makes a good substitute for the Tuna in this casserole.
  • This recipe is in The Cozy Cookbook on page 186!

To Prepare as a Skillet Meal (Without Baking):

  • Boil the noodles until fully cooked (vs. boiling for 1 minute less).
  • Top the casserole with Parmesan cheese. Cover and simmer over medium heat until warm and bubbling, 5-10 minutes.
  • Add a topping that doesn’t require baking to become crispy, such as crushed Ritz (without melted butter mixed in), or potato chips. 

Storage

  • Store in an airtight container and refrigerate for up to 3 days or freeze for up to 3 months.

This classic Tuna Noodle Casserole has canned tuna and egg noodles smothered in a creamy mushroom soup filling with cheese and peas. Top it off with buttery Ritz crackers, crispy fried onions, or potato chips.

Ingredients

  • 3 cups dry egg noodles, about 4 cups cooked
  • 2 chicken bouillon cubes, optional
  • 8 oz. shredded White Cheddar cheese
  • 2 Tablespoons butter
  • 1 rib Celery, diced
  • ½ yellow onion, diced
  • 2 cloves garlic, minced
  • 2 cans solid white albacore tuna in water, drained. (5 oz. per can)
  • ½ teaspoon Salt
  • ½ teaspoon celery salt
  • ¼ teaspoon Pepper
  • 1 (10.5 oz.) can condensed cream of mushroom soup, or try my homemade version
  • 1.5 cups half and half, see notes
  • 1/2 cup sour cream, at room temp
  • 1 cup frozen peas
  • 1/3 cup Parmesan cheese, shredded

Casserole Topping

  • 1 cup Ritz crackers, crushed
  • 2 Tablespoons butter, melted

Optional Garnish

  • 3 green onions, diced

Instructions

  • Preheat oven to 400°F.
  • Shred the cheese and set aside to allow it to come to room temperature.
  • Melt the butter in a large skillet over medium heat. Add the diced onions and celery and cook for about 5 minutes, until softened.
  • Add the minced garlic and cook for an additional minute.
  • Decrease heat to low. Add the drained tuna, salt/pepper, celery salt, cream of mushroom soup, half and half, and sour cream. Stir until combined. Gradually sprinkle in the White cheddar and stir until well-combined and smooth.
  • Cook the egg noodles 1 minute shy of what the package instructs. Add 2 bouillon cubes to the boiling water to enhance the flavor of the egg noodles if desired.
  • Add the peas and drained egg noodles to the cream sauce and use a silicone spatula to gently stir until combined.
  • If not using an oven safe skillet, transfer to a lightly greased 9 x 13 casserole dish.
  • Top with Parmesan cheese. Cover and bake for 20 minutes.
  • Combine the Ritz crackers and melted butter and sprinkle over the casserole. Bake uncovered for 5-7 minutes, until the top is brown and crisp.
