Smashed Potatoes with Tonnato Sauce: A Modern Take on an Italian Classic
Crispy smashed potatoes have become a beloved comfort food—celebrated for their irresistible texture and flavor. When paired with tonnato sauce, a creamy, tangy Italian condiment made from tuna and anchovies, they transcend mere snack status and become a vibrant, crowd-pleasing appetizer. This article delves into the technique and magic of combining smashed potatoes with tonnato sauce, reflecting on its origins, preparation, and the unique harmony of flavors and textures that make this dish exceptional.
What Are Smashed Potatoes?
Smashed potatoes are distinct from mashed potatoes; instead of being whipped into a purée, boiled potatoes are gently flattened and then roasted until their craggy surfaces become golden and crisp. The method maximizes the potato’s interior fluffiness while offering maximum crunch—turning every bite into a celebration of contrast.
- Rustic charm: Smashed potatoes are visually enticing thanks to their jagged edges and irregular shapes.
- Textural complexity: The technique ensures extra crispy surfaces alongside tender interiors.
- Versatility: Delicious alone, smashed potatoes also act as ideal vehicles for flavorful sauces and toppings.
What is Tonnato Sauce?
Tonnato sauce is an iconic Italian condiment, originating from the northwestern Piedmont region. Traditionally paired with veal in the dish vitello tonnato, this sauce marries canned tuna, anchovies, capers, mayonnaise, and lemon juice to deliver a rich, tangy, and deeply savory flavor. The fusion of creamy and seafood notes perfectly complements potatoes’ earthy neutrality.
- Umami-rich: Anchovies and tuna provide depth and savory intensity.
- Creamy consistency: Mayonnaise binds ingredients for a luxurious texture.
- Bright acidity: Lemon and capers brighten and balance richness.
Why Pair Smashed Potatoes with Tonnato Sauce?
The pairing succeeds because it unites three culinary elements:
- Contrast: Crispy, warm potatoes juxtaposed with a cool, creamy sauce.
- Balance: Starchiness tempers the sharpness and umami of tonnato.
- Flavor layering: Herbs and seasoning in both components add complexity and intrigue.

Step-by-Step: How to Make Ultra-Crispy Smashed Potatoes with Tonnato Sauce
-
1. Cook the Potatoes
Boil small waxy potatoes until just fork-tender—do not overcook, or they’ll fall apart during smashing. Drain, then allow to steam dry for optimal crispiness. This step is crucial for developing a crunchy exterior in roasting.
-
2. Smash and Season
Place the potatoes on a baking sheet, spacing evenly. Use a flat-bottomed glass or potato masher to gently flatten each spud—aim for roughly half-inch thickness. The more uneven and jagged the surface, the more crunch you’ll achieve.
Generously drizzle with olive oil, sprinkle with salt and pepper, and add your preferred fresh herbs.
-
3. Roast to Perfection
Roast in a hot oven (ideally 450°F / 230°C) for 25-35 minutes. Turn halfway through if desired, but leaving them undisturbed ensures better crunch. Bake until the surfaces are deeply golden and edges are audibly crisp.
-
4. Make the Tonnato Sauce
While potatoes cook, prepare the tonnato:
- Blend or process canned tuna, anchovies, mayonnaise, drained capers, a splash of lemon juice, and a dash of pepper until smooth and creamy.
- Taste and adjust with more lemon, capers, or anchovy as needed. The finished sauce should be thick, spoonable, and balanced between tangy and salty.
-
5. Assemble and Serve
Layer the crispy potatoes on a serving platter. Either spoon the tonnato sauce over each potato or serve alongside for dipping. Finish with a sprinkle of fresh herbs, extra capers, or grated lemon zest for color and brightness.
Serve warm or at room temperature and watch them disappear!
Tips for Outstanding Smashed Potatoes
- Choose small, waxy potatoes: Yukon Golds and fingerlings crisp best and hold their shape.
- Let potatoes steam dry: Moisture inhibits crisping; dry potatoes deliver crunch.
- Don’t skimp on oil: Generous olive oil ensures maximum browning.
- Flavor boosters: Add garlic powder, paprika, or Parmesan before roasting for variation.
- Serve immediately: Potatoes are at their crispest straight from the oven.
The Tonnato Sauce Advantage: Variations and Usage Ideas
Though classic, tonnato sauce is endlessly adaptable. It’s a standout not just with potatoes but across a variety of dishes:
- Sandwich spread: Slather tonnato on ciabatta for a speedy, luxurious lunch.
- Roasted vegetables: Serve with artichokes, asparagus, or broccoli.
- Proteins: Use with roasted chicken, grilled steak, or, as in Italian tradition, thin-sliced veal.
Serving Suggestions: Making It a Meal
Smashed potatoes and tonnato can anchor a menu or work as a showstopping starter in a dinner party spread. Pair them with:
- Simple leafy salads with a sharp vinaigrette
- Chilled vegetable sides—think roasted red peppers or green beans
- Crusty bread, olives, and a robust Italian red or white wine
Frequently Asked Questions (FAQs)
Q: Which potatoes work best for smashing?
A: Small, waxy varieties like Yukon Gold, fingerlings, or baby reds offer the ideal creamy texture and crisp crust.
Q: Can I make smashed potatoes ahead of time?
A: Yes. Parboil and smash up to 6 hours ahead, then roast just before serving for maximum crunch. Reheating in a hot oven works, but the crispiness may diminish slightly.
Q: How can I adjust the tonnato sauce for dietary needs?
A: Substitute light mayonnaise or Greek yogurt for less richness; skip anchovies for pescatarian diets, though flavor will change.
Q: Is tonnato sauce fishy?
A: While made from tuna and anchovies, proper balance delivers a mellow umami flavor rather than pronounced fishiness. Adjust quantities to taste.
Q: Can I store leftovers?
A: Store potatoes and sauce separately. Potatoes keep for 2-3 days refrigerated; re-crisp in a hot oven. Sauce keeps for up to 3 days in a sealed container.
