Smashed Potatoes with Sweet Corn Relish: A Fresh & Vibrant Summer Plate
A lively summer recipe pairing crispy potatoes, zesty sweet corn relish, and vibrant spring pea sauce for a colorful plant-forward feast.
Smashed Potatoes with Sweet Corn Relish
There are few things as visually joyful and flavor-packed as a plate of smashed potatoes crowned with tangy sweet corn relish and vibrant green pea sauce. This bold, vegetable-forward recipe is a celebration of summer’s bounty—it’s fresh, zippy, and puts produce front and center, making for a side or main that feels like a festive spread on any table. Whether you’re piling up your plate at a picnic or looking for a centerpiece-worthy vegetarian main, these smashed potatoes with their colorful accompaniments are a pure showcase of the season.
Why Smashed Potatoes?
The beauty of smashed potatoes lies in their irresistible contrast—crispy edges and soft, fluffy insides. By boiling and then gently smashing small new potatoes, you maximize their surface area, so they soak up the flavors of caramelized onions and sweet, tart relish, while crisping up beautifully in the oven or skillet. Their blank-canvas nature pairs excellently with the assertive, sweet-spicy notes of the corn relish and the fun verdancy of the spring pea sauce.
The Inspiration
This recipe draws inspiration from classic summer picnic fare: smashed or roasted potatoes, corn relish, and bright veggie sauces all have deep roots in casual, communal dining. The fresh relish provides a crunchy, puckery counterpoint to the deep savoriness of potatoes, and the green pea sauce delivers a punch of color and subtle heat, making every bite layered and lively.

How to Make Smashed Potatoes with Sweet Corn Relish
1. Sweet Corn Relish
This vibrant relish can be made ahead, gaining flavor as it sits. It’s loaded with fresh corn kernels, tomatoes, red onion, bell pepper, jalapeño, and garlic, all quick-pickled in a fragrant brine of rice vinegar, raw cane sugar, mustard seeds, cumin seeds, turmeric, black peppercorns, and a hit of salt. Make extra—it’s fantastic on burgers, hot dogs, or grain bowls.
- Blanch the corn: Boil corn briefly, then shock in ice water. Cut kernels from cobs.
- Combine aromatics: In a jar, mix corn with tomatoes, onion, bell pepper, jalapeño, and garlic.
- Make the brine: Simmer vinegar, water, sugar, mustard and cumin seeds, salt, peppercorns, and turmeric until sugar dissolves.
- Pickle: Pour brine over corn mixture. Cover and refrigerate at least a day (up to a year!), allowing flavors to meld.
2. Spicy Spring Pea Sauce
This sauce brings a creamy, fresh element and vibrant color to the plate. It’s a simple purée of blanched peas, lemon juice, jalapeño, salt, and white pepper. Adjust consistency with water so it drapes beautifully over potatoes.
- Blanch peas: Quickly simmer fresh or frozen peas with salt, then rinse under cold water to preserve color.
- Blend: Purée peas with jalapeño, lemon juice, and salt. Add water gradually for a smooth, pourable sauce.
- Season: Taste and tweak with more salt, pepper, or lemon as you like.
3. Perfect Smashed Potatoes
New potatoes are boiled, then smashed to increase surface area and create those coveted crispy edges. They’re finished on a hot skillet or pan with plenty of oil and caramelized onions for depth and bold savoriness.
- Boil potatoes: Simmer whole small new potatoes until just fork-tender. (Larger potatoes can be cut to size.)
- Smash gently: Place potatoes on a board or tray and lightly press so they split but hold together.
- Caramelize onions: In oil, cook sliced onions slowly until golden and sweet. Season with salt and pepper.
- Pan-fry potatoes: In a wide skillet, sear potatoes cut-side-down in oil until crisp and browned on both sides.
Assembly & Serving
To plate, arrange the smashed potatoes on a wide platter. Spoon over lush golden-brown onions, then top with generous spoonfuls of bright sweet corn relish. Drizzle or serve the vivid green pea sauce alongside. Add a final grind of black pepper and a scatter of fresh herbs if you have them (parsley or cilantro work perfectly).
- For a heartier meal: Top with grilled or roasted protein of your choice (such as shrimp or tofu), or pair with a fresh green salad.
- Leftovers: Store components separately for best texture; assemble just before serving.
Customize This Dish
- Swap new potatoes for fingerlings or small Yukon Golds, adjusting cooking time as needed.
- Dial up the heat by using a hotter pepper in the relish or pea sauce.
- Add fresh herbs (like dill, basil, or chives) to the relish for burst of extra flavor.
- Grill instead of pan-frying the smashed potatoes for a smoky, charred finish.
Tips for Success
- Plan ahead: The corn relish improves after at least a day in the fridge—try to make it in advance.
- Don’t rush the onions: Slow caramelization brings out sweetness and complexity.
- Achieve the balance: Taste each component individually and season to your preference, then taste together and adjust for a perfect harmony of acidity, sweetness, and heat.

Frequently Asked Questions (FAQs)
Q: How far ahead can I make the sweet corn relish?
A: The relish can be made up to a week or even several months ahead. Its flavor deepens the longer it sits in the fridge, so making it at least 24 hours ahead is recommended. Store in a clean, airtight jar for up to a year.
Q: Can I use frozen corn or peas if fresh aren’t available?
A: Yes! Substitute frozen sweet corn (thawed and drained) and frozen peas for fresh if needed—just adjust blanching time as frozen vegetables may cook faster.
Q: What kind of potatoes work best for smashing?
A: Use small new potatoes, fingerling, or baby golden/yellow potatoes. Avoid starchy baking potatoes; waxy or creamy-textured varieties hold together best.
Q: How can I make the dish spicier?
A: Add extra minced jalapeño or a dash of hot sauce to either the sweet corn relish or the spring pea sauce.
Q: Is this dish good for serving a crowd?
A: Absolutely. Prepare all components ahead and assemble just before serving. The recipe scales well and adds cheerful color to buffets and potlucks.
