Seasonal produce transforms rustic bread into a vibrant summer meal.

Corn, Avocado, and Radish Tartine
Few summer dishes feel as lively and fresh as an open-faced tartine piled high with seasonal produce. Corn, avocado, and radish tartine brings together the sweetness of just-picked corn, the silkiness of ripe avocado, and the peppery crunch of fresh radishes, all atop a sturdy slice of toasted country bread. This bright recipe is endlessly adaptable, quick to assemble, and ideal for warm-weather lunches, picnics, and brunch spreads.
What Is a Tartine?
The term “tartine” hails from France, referring to an open-faced sandwich. Traditionally, a tartine showcases simple, high-quality ingredients arranged artfully on crusty bread, letting each element shine. Unlike a closed sandwich, the tartine’s exposed surface provides a canvas for color and texture, while inviting bold flavors and vibrant assemblages.
Why This Recipe Works
- Seasonal Corn: Fresh summer corn adds delicate sweetness and juicy texture. Quick cooking preserves its snap and flavor.
- Ripe Avocado: Creamy avocado brings satisfying richness, mellowing out the brightness of raw vegetables.
- Crunchy Radishes: Radishes lend peppery bite and crisp crunch, balancing the silkiness of avocado.
- Lemon Juice: A touch of lemon keeps avocados vibrant and adds acidity for balance.
- Artisan Bread: Toasted country loaf offers crunch and sturdy support for toppings.

Ingredient Spotlight
Corn
Sweet summer corn offers a burst of juicy flavor and is best when harvested at peak ripeness. Whether raw or quickly cooked, its natural sugars bring a mellow contrast to spicier and richer elements on the tartine.
Avocado
Known for its creamy texture, avocado provides heart-healthy fats, a mild grassy flavor, and an ideal base for layering. Squeeze of lemon juice helps maintain its fresh color.
Radish
Crisp and peppery, radishes contribute a welcome crunch and lively bite. French breakfast, watermelon, or classic red varieties work well; for more color, mix types together.
Choosing and Preparing Your Bread
A good tartine begins with excellent bread. Opt for a dense country-style loaf, sourdough, or whole wheat. Slices should be thick enough to withstand toppings but not so thick as to dominate the flavors. Toasting brings out nutty aromas and ensures a crunchy foundation.
- For Gluten-Free Tartine: Substitute your favorite gluten-free boule or seeded bread.
- For Added Flavor: Brush with olive oil or rub with garlic before toasting.
Nutritious and Quick
This tartine is as nourishing as it is visually stunning. Packed with vitamins, minerals, fiber, and healthy fats, it satisfies hunger without weighing you down—ideal for busy weekdays or leisurely weekends.
Make-Ahead & Storage
- Corn & Radish Prep: Prepare up to one day in advance; store in airtight containers in the fridge.
- Avocado: Slice fresh to prevent browning. To delay oxidation, toss slices in lemon juice or keep the pit with unused halves.
- Bread: Toast immediately before serving for best crunch.
- Assembly: Layer all elements just before eating. Tartines are best consumed immediately; assembled tartines may become soggy if held too long.
Pairings
- Wine: Crisp rosé, Sauvignon Blanc, or Vinho Verde.
- Beer: Light Belgian ales or wheat beers complement the vegetables.
- Non-Alcoholic: Sparkling water with citrus, iced herbal tea, or lemonade.
