If you’re like most people, you probably pop open a can of tuna, drain the oil into the sink, and move on with your meal. But what if I told you that the oil you’ve been tossing away is actually liquid gold for your kitchen?

Yes — that humble tuna can oil (especially if it’s packed in olive oil) can add incredible flavor, richness, and nutrition to your dishes. Instead of wasting it, you can transform it into a secret ingredient that makes everyday meals taste gourmet.

Let’s dive into why you should stop pouring it down the drain — and how to use it like a pro.

🥄 Why You Should Save Tuna Oil

That oil isn’t just oil. It’s infused with savory, umami-rich tuna essence — meaning it’s already flavored in a way that enhances many dishes, from salads to sauces.

If your tuna is packed in olive oil, you’re getting heart-healthy fats and a subtle, seafood-forward flavor that can elevate everything from pasta to roasted vegetables.

And the best part? You’re cutting down on food waste and getting more out of what you buy. Win-win.

🌿 5 Genius Ways to Use Tuna Can Oil in Your Cooking

1. Whisk It into Salad Dressings

Swap out some (or all) of your olive oil for tuna oil in vinaigrettes. It adds depth and a hint of oceanic richness — perfect for Mediterranean salads with tomatoes, capers, and olives.
Try this:
Whisk together 2 tbsp tuna oil, 1 tbsp lemon juice, ½ tsp Dijon mustard, and a pinch of salt and pepper. Drizzle over greens or grilled vegetables.

2. Sauté or Roast with It

Instead of using plain olive oil, try brushing tuna oil on vegetables before roasting. It’s especially great for asparagus, zucchini, potatoes, or bell peppers. The subtle savory flavor brings a restaurant-quality touch.

You can also use it to sauté garlic and onions at the start of a pasta sauce — it adds umami complexity right from the base.

3. Make a Flavor-Packed Pasta Dish 🍝

Tuna oil is made for pasta. Toss cooked spaghetti or linguine with the oil, flaked tuna, lemon zest, garlic, and parsley.
Quick Recipe:

• 1 can tuna (with oil reserved)

• 2 cloves garlic, minced

• 1 tbsp capers

• Juice and zest of ½ lemon

• Cooked pasta

Heat the garlic gently in the tuna oil, stir in the tuna and capers, then toss with pasta and lemon. Add chili flakes if you like a little heat. Dinner, done!

4. Use It in Marinades

Tuna oil can be a wonderful base for seafood or chicken marinades. Blend it with herbs, citrus, and a touch of vinegar. The oil helps tenderize while infusing deep, savory flavor.

Try:
Tuna oil + chopped parsley + garlic + lemon juice + a splash of soy sauce = a killer marinade for grilled shrimp or vegetables.

5. Turn It into a Savory Spread or Dip

Mix tuna oil with a little mayonnaise, lemon juice, and a pinch of smoked paprika for a Mediterranean-inspired sandwich spread. Or blend it into hummus or white bean dip for extra richness.

💡 Bonus Tip: Store It Smartly

If you’re not using it right away, strain the oil into a small airtight jar and refrigerate it for up to 3 days. Use only the oil from high-quality tuna packed in olive oil (not vegetable or soybean oil) for the best flavor and health benefits.
