Should I Throw the Oil in Canned Tuna? A Guide

4 min read

While many people reflexively pour canned tuna oil down the drain, experts confirm this flavorful liquid is safe and often beneficial for consumption. The decision to drain or keep it ultimately depends on the specific type of tuna and your recipe goals.

Quick Summary

The debate over draining tuna oil hinges on the packing medium: oil-packed varieties offer richer flavor and nutritional benefits, while water-packed liquid is typically drained. Factors like diet, recipe, and oil quality all inform the best approach to handling canned tuna.

Key Points

  • Check the Packaging: The decision to keep or drain the oil depends on whether your tuna is packed in oil or water.

  • Use High-Quality Oil: If the tuna is packed in high-quality olive oil, it's a flavorful and safe ingredient rich in omega-3s and Vitamin D.

  • Ditch for Calorie Control: For a lower-calorie, lower-fat option, drain the oil completely. Oil-packed tuna has more than double the fat of water-packed.

  • Repurpose with Recipes: Don't throw out oil from quality cans; use it to create salad dressings, sauté vegetables, or enhance sauces.

  • Drain for Classic Salad: For a classic, non-greasy tuna salad, draining the oil ensures a better texture and consistency.

  • Use the Lid for Draining: A mess-free way to drain is to use the can's lid to press down on the tuna and pour out the liquid.

To Drain or Not to Drain? The Great Tuna Oil Debate

The question of whether to discard the oil from canned tuna is a common one, with the answer being more nuanced than a simple 'yes' or 'no'. The decision largely depends on two key factors: the type of liquid the tuna is packed in and your intended use for the fish. Different packing methods offer distinct flavor, texture, and nutritional profiles that cater to various culinary needs. Understanding these differences is the first step toward making a more informed and less wasteful choice in the kitchen.

Oil-Packed vs. Water-Packed Tuna

Canned tuna comes primarily in two forms: packed in water and packed in oil, most commonly olive oil or a less expensive vegetable oil. The choice between the two has a significant impact on the final product.

  • Oil-Packed Tuna: This variety is celebrated for its richer, more succulent flavor and texture. The oil infuses the fish, preventing it from drying out and enhancing its taste. For high-quality olive oil varieties, the oil itself is a valuable, flavorful ingredient. Research has even shown that this oil can absorb beneficial omega-3 fatty acids from the tuna, making it a nutritious addition to dishes. However, oil-packed tuna is also higher in calories and total fat than its water-packed counterpart, a factor to consider for those monitoring their intake.
  • Water-Packed Tuna: This type is preferred by those seeking a lighter, leaner option. The water-packed tuna has a milder, less pronounced flavor and a firmer, flakier texture. While it has fewer calories and less fat, some of the fish's natural juices and omega-3s can be lost when the water is drained. This variety is generally better suited for recipes where you want a cleaner, more classic tuna flavor without the added richness of oil.

Creative Ways to Repurpose Tuna Oil

For those who use oil-packed tuna, throwing away the leftover liquid is a missed opportunity. This infused oil is packed with flavor and can be repurposed in numerous ways, reducing food waste and adding a unique twist to your cooking.

  • Flavorful Dressings and Vinaigrettes: Use the oil as the base for a salad dressing, combining it with vinegar, lemon juice, herbs, and spices. It pairs especially well with Mediterranean-style salads featuring tomatoes, cucumbers, and capers.
  • Sautéing Vegetables: Sauté onions, garlic, and other vegetables in the tuna oil to give them an extra layer of savory, oceanic flavor. This works perfectly as a base for pasta sauces or seafood stews.
  • Enhancing Sauces: Stir the oil into a homemade or jarred red sauce to boost its umami depth. The subtle fish flavor complements a wide range of tomato-based dishes.
  • Cooking Eggs: For a quick, flavorful breakfast or light meal, fry eggs in the saved tuna oil. It's a simple way to elevate a standard dish with minimal effort.
  • Pasta Dishes: When making a simple pasta dish with canned tuna, incorporate the oil directly into the recipe along with other ingredients like olives, garlic, and fresh herbs. This helps create a cohesive, flavorful sauce. The oil from canned fish can even be used as the base for a mayonnaise-based sauce called tonnato.
  • Making Tuna Cakes or Patties: If you are draining your tuna for a recipe like tuna cakes, you can use a portion of the saved oil to fry them, giving the final product an even richer taste.

When is it best to drain the oil completely?

While using the oil is often beneficial, there are certain situations where draining it is the best option:

  • Calorie Control: If you are closely monitoring your fat and calorie intake, draining the oil is the right move. Oil-packed tuna can have more than double the fat of its water-packed counterpart.
  • Preventing Greasiness: For certain recipes like a classic tuna salad made with mayonnaise, retaining the oil can make the mixture overly greasy and affect the texture. Draining allows for better control over the final consistency.
  • Specific Flavor Profiles: If your recipe calls for a cleaner, less fishy flavor profile—perhaps in a casserole or a dish where the tuna is a subtle ingredient—draining the oil ensures it doesn't overpower other components.

Tuna in Oil vs. Tuna in Water Comparison

Feature Oil-Packed Tuna Water-Packed Tuna
Flavor Richer, more pronounced, and succulent due to the infused oil. Milder, cleaner, and more subtle, allowing the natural tuna flavor to shine.
Texture Softer and more tender, as the oil coats the fish flakes. Firmer and flakier, holding its shape better in some dishes.
Calories Higher, with a standard 4-ounce serving containing more than double the fat of water-packed tuna. Lower in calories and fat, a suitable choice for a weight-conscious diet.
Omega-3s Retains or even absorbs more omega-3s, but some are lost when drained. Contains omega-3s, which are largely retained if the liquid isn't drained entirely.
Best For Salads, pasta dishes, and gourmet sandwiches where a richer flavor is desired. Classic tuna salad, casseroles, and dishes requiring a leaner, firmer texture.

Conclusion: Make the Right Choice for Your Plate

Ultimately, the choice of whether to throw away the oil in canned tuna is a personal one, driven by taste preferences, dietary needs, and culinary goals. For those who prioritize a richer flavor and moist texture, leaving the oil in or using it in creative ways is a fantastic option. The infused oil is a safe, flavorful, and nutritious ingredient that can elevate a variety of dishes. Conversely, if you're counting calories or prefer a firmer, cleaner tuna flavor, draining the oil is the best course of action. By considering the type of tuna and your recipe's requirements, you can make the most of this versatile, budget-friendly pantry staple without letting a drop go to waste. https://www.tastingtable.com/1234683/ways-to-use-up-leftover-oil-from-a-can-of-tuna/
