Frequently Asked Questions

Can I Make Patate Tonnate Ahead of Time?

Absolutely. It actually tastes better when made a few hours in advance so the flavors can meld.

What Type of Tuna Should I Use?

Go for canned tuna in olive oil for the best flavor, but tuna in water works too if you're keeping it lighter.

Is Patate Tonnate Served Warm or Cold?

It’s best served cold or at room temperature, making it perfect for picnics and potlucks.

Can I Substitute the Mayonnaise?

Add anchovies, olives, or boiled eggs for an extra punch. You can also toss in green beans or steamed carrots for color and crunch.

How to Store Italian Potato Salad

Place any leftovers in an airtight container and store them in the refrigerator for up to 3 days. Before serving again, give the dish a gentle stir and, if needed, add a spoonful of mayo or lemon juice to revive the creaminess.

How to Freeze Italian Potato Salad

This dish is not ideal for freezing, as the creamy sauce may separate and the potatoes can become mushy once thawed. For best results, enjoy it fresh or refrigerated within a few days.

How to Make The Best Italian Tuna Potato Salad

Boil the potatoes: Place unpeeled potatoes in a pot of cold water. Bring to a boil and cook for 20–25 minutes until fork-tender. Let them cool slightly, then peel and slice.
