Is Canned Tuna Better in Water or Olive Oil?

4 min read

According to the USDA, a 5-ounce can of tuna packed in oil contains approximately 280 calories, while the same size can in water has only about 120 calories. The question of whether canned tuna is better in water or olive oil depends on more than just calories, with taste, texture, and culinary application playing a significant role in your choice.

Quick Summary

This guide breaks down the core differences between canned tuna packed in water and olive oil, focusing on nutritional content, flavor, texture, and best uses. It examines which option is ideal for different dietary needs and culinary applications, helping you make an informed decision based on your preferences.

Key Points

  • Nutritional Differences: Canned tuna in water is significantly lower in calories and fat, while olive oil-packed tuna is higher in both due to the added oil.

  • Flavor Profile: Water-packed tuna has a milder, cleaner flavor, whereas olive oil-packed tuna is richer and more pronounced.

  • Texture Contrast: The water-packed variety offers a firmer, flakier texture, while oil-packed tuna is softer and more succulent.

  • Ideal Uses: Water-packed tuna is best for recipes like tuna salad and casseroles, where you control added fats. Olive oil-packed tuna is ideal for pasta, antipasti, and dishes where its rich flavor can enhance the sauce.

  • Versatility: Water-packed tuna acts as a versatile, low-fat protein base, while the oil from olive oil-packed tuna can be used as a flavorful ingredient itself.

  • Consider the Source: For a sustainable choice, look for pole-and-line caught skipjack tuna, which is lower in mercury than larger tuna species.

Water-Packed Tuna: The Calorie-Conscious and Versatile Choice

For those focused on minimizing calorie and fat intake, water-packed canned tuna is the clear winner. The tuna is sealed in a can with water, which results in a milder, less pronounced flavor and a firmer, flakier texture compared to its oil-packed counterpart. This makes it a highly versatile ingredient that acts as a blank canvas for other flavors.

Water-packed tuna is perfect for classic dishes like tuna salad, where you want to control the type and amount of fat you add, such as mayonnaise or avocado. Its firmer texture also holds up well in dishes like tuna patties or casseroles. While some claim that water-packing can leach out some of the fish's natural oils and flavor, research indicates that it can retain more DHA, an important omega-3 fatty acid, compared to oil-packed varieties.

Best uses for water-packed tuna:

  • Tuna salad
  • Tuna patties or burgers
  • Casseroles
  • Protein-rich wraps and sandwiches
  • Light, refreshing salads

Olive Oil-Packed Tuna: Rich Flavor and Luxurious Texture

Canned tuna packed in olive oil offers a distinctly richer and more pronounced flavor, along with a softer, more succulent texture. The oil infuses the fish, making it a more gourmet and ready-to-eat option straight from the can. While this does result in a higher calorie and fat content, the fats from olive oil are heart-healthy monounsaturated fats. Furthermore, the oil helps preserve the tuna's moisture, preventing it from drying out.

Many chefs and tuna connoisseurs prefer oil-packed tuna for its depth of flavor. It excels in recipes where the oil can be incorporated into the dish itself, such as pasta salads, antipasti, or drizzled over crusty bread. It’s also often made with higher-quality cuts of fish, though this depends on the specific brand. The oil itself can even be repurposed for making salad dressings or sautéing vegetables, reducing food waste.

Best uses for olive oil-packed tuna:

  • Pasta dishes, like a tuna puttanesca
  • Gourmet salads, such as a Niçoise salad
  • Antipasti or crostini
  • Marinades and sauces
  • Drizzled over warm potatoes or roasted vegetables

Which to Choose: Water vs. Olive Oil

When deciding between water-packed and oil-packed canned tuna, your personal health goals and culinary intentions should guide your choice. For a high-protein, low-fat meal, water-packed is the ideal base. For a richer, more flavorful dish, oil-packed is the better option. The choice also depends on the species of tuna, with albacore often found in water for a milder taste and yellowfin frequently packed in oil for its lean, firm texture.

It's important to read labels carefully, as some products packed in water or oil may have added salt or different species of tuna. Opt for brands with BPA-free cans to avoid potential chemical exposure.

Feature Tuna Packed in Water Tuna Packed in Olive Oil
Flavor Milder, cleaner, and less pronounced Richer, more pronounced, and savory
Texture Firmer and flakier Softer, more moist, and succulent
Calories Lower (approx. 120 cal per 5 oz) Higher (approx. 280 cal per 5 oz)
Fat Content Lower (less than 1g fat per oz) Higher (approx. 2.3g fat per oz)
Best For Tuna salad, sandwiches, casseroles Pasta dishes, gourmet salads, antipasti
Primary Use Versatile, lean protein base Ready-to-eat flavor enhancer

How to Maximize Nutrition and Flavor

Regardless of your choice, you can maximize the nutritional benefits and flavor of canned tuna. When using water-packed tuna, you can rinse it to reduce sodium content before adding your own preferred seasonings and healthy fats like avocado or extra-virgin olive oil. For oil-packed tuna, consider using the leftover oil in your recipe to add extra flavor and heart-healthy fats.

For those seeking a compromise, some high-quality brands pack tuna in a minimal amount of oil, offering a balanced flavor and calorie count. Another consideration is the species of tuna; skipjack (light) tuna is generally lower in mercury than albacore (white) tuna because it's a smaller, faster-growing fish. For information on sustainable fishing practices, organizations like the Marine Stewardship Council (MSC) can offer guidance on eco-friendly brands.

Conclusion

The debate over whether canned tuna is better in water or olive oil ultimately comes down to your dietary goals and culinary preferences. Water-packed tuna is the go-to for those seeking a low-calorie, high-protein option with a clean, versatile flavor. Olive oil-packed tuna, on the other hand, is a more indulgent choice, offering richer flavor and a softer texture that's perfect for gourmet applications. By understanding the differences, you can choose the right can of tuna for your next meal and maximize both flavor and nutrition.

Frequently Asked Questions

Neither is inherently 'healthier'—it depends on your goals. Water-packed tuna is lower in calories and fat, making it better for weight management. Oil-packed tuna has more calories but also more heart-healthy fats, especially if packed in olive oil.

Yes, draining the oil from oil-packed tuna can significantly reduce the calorie and fat content, making it closer to the nutritional profile of water-packed tuna. However, you'll also lose some of the infused flavor.

Yes, it can. While both contain omega-3s, some studies suggest that tuna packed in water may retain more DHA, an important omega-3 fatty acid, while oil-packed varieties may have higher levels of vitamin D and other minerals.

Water-packed tuna is often preferred for classic tuna salad. Its firmer, flakier texture and neutral flavor allow you to add your own fats, like mayonnaise or avocado, to control the taste and creaminess.

Olive oil-packed tuna is ideal for pasta dishes. The rich oil enhances the sauce and provides a more tender, flavorful tuna that complements other ingredients.

Yes, the leftover oil from olive oil-packed tuna can be used to add flavor to other dishes. It's excellent for making salad dressings, sautéing vegetables, or using in marinades.

The mercury level is more dependent on the species of tuna than the packing liquid. Skipjack (light) tuna is smaller and faster-growing, so it typically has lower mercury levels than larger albacore (white) tuna.
