Ingredients for potato and canned tuna
Potatoes, tuna, and a handful of pantry staples—this pâté is restaurant-quality without the fuss.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 ½ lb | Peeled and cubed evenly |
| Canned Tuna in Water 🐟 | 2 cans | 5 oz each, drained well |
| Mayonnaise 🥛 | ½ cup | Full-fat preferred for creaminess |
| Greek Yogurt 🥛 | ½ cup | Plain, full-fat for texture |
| Fresh Lemon Juice 🍋 | 2 tbsp | Freshly squeezed, seeds strained |
| Lemon Zest 🍋 | 1 tbsp | Finely grated, vibrant color |
| Fresh Parsley 🌿 | ¼ cup | Chopped, stems removed |
| Garlic Cloves 🧄 | 2 cloves | Minced, fresh preferred |
| Dijon Mustard 🍯 | 1 tbsp | For tangy depth |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For richness and flavor |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for heat |
| Crusty Bread 🍞 | 8 slices | For serving, any variety |
The potatoes are the foundation, so Yukon Golds are ideal—they stay creamy and don’t turn gluey. I grab them from Whole Foods or the organic section at Kroger—they’re worth the slight price bump. For the tuna, Wild Planet or Starkist in water are my go-tos; skip the oil-packed stuff unless you’re craving extra richness. The Greek yogurt adds tang without overpowering, but full-fat mayo works too if you’re not watching calories. Fresh lemon zest makes all the difference—zest it yourself instead of using bottled, even if it’s a pain.
No Greek yogurt? Sour cream or extra mayo keeps the texture creamy. Running low on parsley? Chives or dill work in a pinch, though parsley’s bright flavor is hard to beat. Want more depth? Add 1 tsp smoked paprika or a dash of hot sauce. The Dijon mustard is non-negotiable for that tangy kick—store-bought is fine, but homemade with whole-grain mustard seeds is next-level. For the olive oil, any good-quality brand works, but avoid the cheap stuff that tastes like soap.
This pâté tastes even better the next day—make it ahead and store in an airtight container for up to 4 days in the fridge. Freezes beautifully for 3 months if you want to prep for meal prep. Serve with toasted crusty bread or crackers, or slather it on sandwiches. The flavors meld perfectly overnight, so don’t rush it. Leftovers? Portion into small containers for easy lunches or snacks.

Step-by-step instructions for one-pan protein-packed pâté
This recipe transforms humble ingredients into a rich, creamy pâté that's ready in one pan.
Parboil the Potatoes for Perfect Texture
Place the 2.5 lb Yukon Gold Potatoes in a large pot and cover with cold water by about 2 inches. Add 1 tsp Salt and bring to a boil over high heat. Once boiling, reduce to a gentle simmer and cook for 12-15 minutes until the potatoes are fork-tender but still hold their shape.
Drain immediately and return them to the pot. Let them steam-dry for 2 minutes while you prepare the remaining ingredients. This step prevents a watery pâté later—don't skip it. The potatoes should feel warm but not sticky when handled.
Create the Flavor Base in the Same Pan
Transfer the warm potatoes to a large oven-safe skillet. In the same pot you boiled them in (no need to rinse), heat 1 tbsp Extra-Virgin Olive Oil over medium heat. Add the 2 minced garlic cloves and sauté for 30 seconds until fragrant—don't let them brown.
Add 1 tbsp Dijon Mustard and stir for 1 minute until it darkens slightly. Pour this aromatic mixture over the potatoes in the skillet. The residual heat will help blend everything together later.
Mix the Creamy Binding Components
In a medium bowl, whisk together the 0.5 cup Mayonnaise, 0.5 cup Greek Yogurt, 2 tbsp Fresh Lemon Juice, and 1 tbsp Lemon Zest. Add 0.25 cup chopped Fresh Parsley and 0.5 tsp Black Pepper, mixing until fully combined. This mixture should be smooth and vibrant—like a bright, tangy dressing.
Open the 2 cans Canned Tuna in Water and drain them thoroughly, pressing gently on the fish with a paper towel to remove excess moisture. Add the tuna to the mayo mixture and fold gently with a spatula. The tuna should be evenly distributed but still visible in chunks.
Combine Everything and Bake to Perfection
Spread the potato mixture evenly in the skillet. Pour the tuna-mayo mixture over the potatoes, using a spatula to gently fold everything together. The potatoes should be fully coated with the creamy mixture—this ensures even flavor distribution.
Transfer the skillet to a preheated 375°F oven and bake for 25-30 minutes until the top is golden brown and the edges are slightly crispy. You'll know it's done when the mixture pulls away from the sides of the pan and has a beautiful caramelized crust.
Serve with Crusty Bread for Ultimate Enjoyment
Remove from the oven and let the pâté rest for 5 minutes before serving. This resting time allows the flavors to meld completely and makes it easier to scoop. The texture should be creamy yet slightly firm—like a thick, flavorful spread.
Spoon generous portions onto 8 slices Crusty Bread and serve immediately. The contrast of the warm, crispy bread with the cool, creamy pâté makes every bite irresistible. Garnish with additional lemon zest and chopped parsley for a pop of freshness and color.
Pro Tips For Making Potato And Canned Tuna
- Parboil First, Roast Second: Yukon Golds hold up better if you blanch them in boiling water for 3 minutes before roasting—cuts down on mushiness when they hit the oven. I used to skip this and ended up with sad, waterlogged potatoes every time.
- Drain, Rinse, Repeat: That canned tuna water? It’s salty and metallic. Drain the tuna, then rinse it under cold water for 10 seconds—removes the worst of the tinny taste without overworking the flakes. (Yes, even if you’re impatient like me.)
- Mix Mayo Last: Fold in the mayonnaise and yogurt right before serving—otherwise, the potatoes will absorb it and turn into a gluey mess. I learned this after serving a batch where the dressing had soaked in for 20 minutes. Not ideal.
- Lemon Zest, Not Just Juice: A quick zest of lemon over the mix brightens the whole dish—way more impact than just juice. Takes 10 seconds and actually changes the outcome. (Your future self will notice.)
Best sauces and condiments for this potato and canned tuna
Classic Mayo-Lemon Base
This bright, creamy sauce is the backbone of the pâté. I blend ½ cup full-fat mayo with ½ cup Greek yogurt for a lighter texture while keeping richness. The 2 tbsp fresh lemon juice and 1 tbsp lemon zest cut through the tuna’s saltiness, creating a perfect balance.
For extra tang, add 1 tsp capers or ½ tsp hot sauce—this is my go-to when I want a little kick. 🍋
Herb-Infused Variations
Fresh herbs elevate this dish instantly. The original recipe calls for ¼ cup chopped parsley, but I often swap in 2 tbsp chopped dill for a Mediterranean twist or 1 tbsp chopped chives for a milder flavor.
For a bold taste, mix 1 tbsp chopped tarragon with the parsley—it pairs beautifully with the lemon and tuna. Always use fresh herbs when possible; dried versions lack the vibrant punch.
Spicy Kick Options
If you love heat, add ½ tsp cayenne pepper or 1 tsp sriracha to the mayo mixture for a slow burn. For a smoky heat, stir in ½ tsp smoked paprika with the Dijon mustard.
I also like adding 1 tbsp finely chopped jalapeños (seeds removed) for a fresh, spicy crunch. These additions work best when balanced with a touch more lemon juice to keep the flavors harmonious. 🌶️
Umami Boosters
For deeper flavor, incorporate umami-rich ingredients like 1 tbsp soy sauce or 1 tsp Worcestershire sauce into the mayo mixture. A splash of fish sauce (1 tsp) amplifies the tuna’s natural oceanic notes.
For a vegetarian-friendly twist, add 1 tbsp nutritional yeast—it adds a cheesy, savory depth without animal products. These tweaks turn a simple pâté into a complex, restaurant-worthy dish.
Crunchy Toppings
Texture contrasts make this pâté even more exciting. Top with toasted breadcrumbs (mix 2 tbsp panko with 1 tsp olive oil and toast in a dry pan) for crunch. I also love adding finely chopped pickles or red onion slices for a tangy bite.
For a gourmet touch, sprinkle crumbled feta cheese on top before serving—it adds a salty, creamy contrast that’s irresistible. 🥖
Warm Sauce Pairings
Serve this pâté with warm, complementary sauces for a full meal. A drizzle of garlic aioli or spicy mayo adds extra richness. For a lighter option, pair it with a lemon-dill yogurt sauce (mix ¼ cup Greek yogurt, 1 tbsp lemon juice, and 1 tbsp chopped dill).
The warmth of the bread and the coolness of the sauces create a perfect balance in every bite.

Frequently asked questions
Can I use oil-packed tuna instead of water-packed?
The recipe works with oil-packed tuna, but you'll need to adjust the mayo slightly. Use ¼ cup less mayo since oil-packed tuna already contains fat. Drain the tuna thoroughly and pat it dry to prevent a greasy texture. The flavor will be richer, but the balance of creaminess might shift slightly.
How do I make this dish ahead of time?
This pâté actually tastes better the next day! Store it in an airtight container in the fridge for up to 4 days. For best results, let it sit at room temperature for 30 minutes before serving to restore its creamy texture. You can also freeze it for 3 months—thaw overnight in the fridge before reheating.
What if I don't have Greek yogurt?
No problem! Substitute with ½ cup extra mayo or ¼ cup sour cream for a similar tangy texture. For a lighter option, use ¼ cup buttermilk or milk> and ¼ cup mayo instead. The dish will still be creamy, though the consistency might be slightly thinner.
Can I make this without baking?
Skip the oven step and mix everything in a bowl instead. Combine the warm potatoes, tuna-mayo mixture, and any remaining ingredients, then fold gently. Let it sit for 10 minutes to thicken slightly. While not as caramelized, it'll still be delicious—great for a quick weeknight meal.
What are the best ways to serve this?
This pâté is incredibly versatile! Serve it with toasted bread or crackers as an appetizer, spread it on sandwiches or wraps for lunch, or use it as a filling for crepes or tacos. For a heartier meal, pair it with roasted vegetables or a simple green salad. It also works beautifully as a dip for veggie sticks or chips>.
