How many calories are in a Tuna Noodle Casserole?

Tuna noodle casserole is a classic American dish that has been around for decades. It’s a hearty, comforting meal that’s budget-friendly and easy to make. But with all the cream, cheese, pasta, and protein packed into a serving, many people wonder just how many calories are actually in a tuna noodle casserole.

What Is Tuna Noodle Casserole?

Tuna noodle casserole is typically made with canned tuna, egg noodles, cream of mushroom soup, milk, and shredded cheese. Some classic recipes also include peas, breadcrumbs or crushed potato chips on top. The ingredients are combined together and baked in the oven until hot and bubbly.

The origins of tuna noodle casserole can be traced back to the Great Depression era. Families needed to stretch their food budgets as far as possible, so casseroles like this became popular since you could make it with pantry staples. The dish gained more mainstream popularity in the 1950s when canned and processed foods became convenience foods that households embraced.

While tuna noodle casserole is an American classic, there are many recipe variations out there. The core ingredients tend to stay the same, but you’ll find options with different types of noodles like egg noodles, rotini or macaroni. There are also renditions made with mushroom soup instead of cream of mushroom soup, or added veggies like celery, onions or bell peppers.

Calories in Tuna

To determine how many calories are in a full tuna noodle casserole recipe, we need to look at the calorie counts for each component. Let’s start with the star ingredient: tuna.

Tuna can be purchased canned either in water or oil. A 3oz (85g) serving of canned tuna in water has approximately:

  • 93 calories
  • 0g carbs
  • 21g protein

For canned tuna in oil, a 3oz (85g) serving has about:

  • 117 calories
  • 0g carbs
  • 23g protein

As you can see, tuna packed in oil contains more calories and fat than tuna canned in water. Depending on the specific recipe, tuna noodle casserole may use anywhere from one to three cans totaling 6-12 ounces of tuna.

Calories in Noodles

Egg noodles are commonly used in tuna noodle casserole. One cup of cooked egg noodles contains:

  • 221 calories
  • 43g carbs
  • 5g protein

Recipes typically call for between 4-8 ounces uncooked egg noodles, which equals 2-4 cups cooked. So the noodles add a significant amount of calories and carbs to the dish.

Calories in Cream Soup

Cream of mushroom soup is the base that brings everything together to create the casserole. One cup of condensed cream of mushroom soup has:

  • 410 calories
  • 29g fat
  • 30g carbs
  • 4g protein

Most recipes call for around two 10.5oz cans of condensed soup totaling 4 cups. Some recipes do substitute regular mushroom soup which is slightly lower in calories at around 290 per cup.

Calories in Milk and Cheese

Milk and shredded cheese add creaminess, texture and extra flavor. One cup of 2% milk contains:

  • 122 calories
  • 4.8g fat
  • 12g carbs
  • 8g protein

And one ounce of shredded cheddar cheese has:

  • 115 calories
  • 9g fat
  • 1g carbs
  • 7g protein

Most recipes use around 1 cup of milk and 1-2 cups shredded cheese.

Calories in Other Ingredients

Beyond the core ingredients, some tuna noodle casserole recipes include extras like:

  • Peas – 1/2 cup has 60 calories
  • Breadcrumbs – 1/4 cup has 63 calories
  • Potato chips – 1 ounce has 154 calories
  • Green onions – 1/4 cup sliced has 8 calories
  • Parsley – 1/4 cup chopped has 2 calories

While these additions do increase the overall calorie count, they generally are low-calorie in smaller quantities.

Total Calories in Tuna Noodle Casserole

The calorie count of tuna noodle casserole can vary depending on the exact ingredients used in the recipe. However, based on the common ingredients and portions listed above, we can estimate a typical tuna noodle casserole has approximately:

  • Tuna (two 6oz cans) – 370 calories
  • Egg noodles (4 cups cooked) – 884 calories
  • Cream soup (four 10.5oz cans) – 1640 calories
  • Milk (1 cup) – 122 calories
  • Cheese (2 cups shredded) – 460 calories
  • Peas (1/2 cup) – 60 calories
  • Total: About 3,536 calories

This equals around 707 calories per serving if divided into 5 servings.

Keep in mind this estimate uses some of the higher-calorie options like regular cream soup, cheese and tuna canned in oil. Choosing lower fat milk, tuna in water, light cream soups or skipping the add-ins would lower the totals.

Ways to Lighten Up Tuna Noodle Casserole

If you’re looking to cut some calories, fat and carbs from tuna noodle casserole, there are several easy modifications you can make:

  • Use tuna canned in water instead of oil
  • Substitute reduced-fat cream soups or regular mushroom soup
  • Use skim or low-fat milk
  • Skip adding potato chips, breadcrumbs or cheese on top
  • Use whole wheat or veggie pasta instead of egg noodles
  • Increase veggies like peas, celery, onions, mushrooms, etc.
  • Replace some noodles with riced cauliflower
  • Season with salt, pepper, garlic powder instead of cheese
  • Opt for Greek yogurt instead of sour cream

With just a few simple tweaks, you can lighten up this comforting classic dish.

How to Burn off the Calories

Tuna noodle casserole has a hearty calorie count at around 700 calories per serving. Here’s how long it would take to burn off those calories with various exercises (calorie burn based on a 155 lb person):

Exercise Calories Burned in 60 Minutes

Jogging (5 mph) 544
Elliptical (moderate effort) 465
Cycling (12-13.9 mph) 711

As you can see, doing higher intensity exercise like jogging, cycling, swimming or HIIT for 60 minutes would burn off most of the 700 calories. More leisurely exercise like walking would take closer to 2 hours to burn the calories from one serving.
