What Makes This Special
Radish & Herb Butter Crostini Garnished With Sunflower Sprouts - Fresh, Crunchy, and Bright
Ingredients
- 1 baguette (or crusty sourdough), sliced into 1/2-inch rounds
- 4 tablespoons unsalted butter, softened to room temperature
- 2 tablespoons extra-virgin olive oil, plus more for brushing
- 1 small garlic clove, finely grated or minced
- 1 teaspoon lemon zest
- 2 teaspoons lemon juice (optional, for a brighter butter)
- 2 tablespoons finely chopped fresh herbs (such as chives, parsley, dill, or a mix)
- 6–8 small radishes, very thinly sliced
- 1 cup sunflower sprouts (also called sunflower microgreens), trimmed
- Flaky sea salt and freshly ground black pepper, to taste
- Optional garnish: a pinch of red pepper flakes, or a drizzle of good olive oil
Instructions
- Prep the bread: Preheat your oven to 375°F (190°C). Arrange baguette slices on a baking sheet and brush both sides lightly with olive oil. Sprinkle with a pinch of salt.
- Toast the crostini: Bake for 8–10 minutes, flipping halfway, until they’re golden at the edges and crisp. Let them cool slightly so the butter doesn’t melt right off.
- Make the herb butter: In a small bowl, combine softened butter, olive oil, garlic, lemon zest, lemon juice (if using), and chopped herbs. Season with a pinch of salt and pepper. Stir until smooth and spreadable.
- Slice the radishes: Use a sharp knife or mandoline to slice the radishes very thin. The thinner the slice, the more delicate the bite. Pat dry with a paper towel if they’re watery.
- Assemble: Spread a generous layer of herb butter on each crostino. Shingle a few radish slices on top. Add a small tuft of sunflower sprouts.
- Finish and serve: Sprinkle with flaky sea salt and a crack of pepper. Add a tiny drizzle of olive oil or a pinch of red pepper flakes if you like a little heat. Serve immediately while the bread is still lightly warm.
There’s a sweet spot where texture, temperature, and flavor meet, and this recipe hits it. You get warm, crunchy crostini topped with cool, silky herb butter, snappy radishes, and lively sprouts.
The herb butter ties everything together with a hint of lemon and garlic. It’s also an adaptable canvas—swap in different herbs, breads, or microgreens and make it your own.
Best of all, you can prep most of it ahead. The herb butter lasts in the fridge for days, and the crostini toast quickly right before serving.
It’s dependable, impressive, and genuinely delicious.

Storage Instructions
- Herb butter: Store in an airtight container in the fridge for up to 5 days, or freeze for up to 2 months.
Let it soften at room temperature before spreading.
- Crostini: Toast the bread ahead and cool completely. Store in an airtight container at room temperature for up to 2 days. Re-crisp in a 325°F (165°C) oven for 5 minutes if needed.
- Radishes and sprouts: Keep radishes uncut in the fridge for up to a week.
Once sliced, store between paper towels in a sealed container and use within a day. Sprouts are delicate—store unwashed in the fridge and rinse just before using; aim to use within 3–4 days.
- Assembled crostini: Best served fresh. If you must prep in advance, assemble no more than 30 minutes ahead to keep the bread crisp.
Health Benefits
- Radishes: Low in calories, high in water, and a source of vitamin C.
Their natural pepperiness comes from compounds that may support digestion.
- Sunflower sprouts: Packed with vitamins A, C, and E, along with plant protein and antioxidants. They bring bright flavor without heavy calories.
- Herbs: Fresh herbs add micronutrients and antioxidants while boosting flavor, allowing you to use less salt.
- Olive oil: Provides heart-friendly monounsaturated fats and helps carry fat-soluble vitamins.
- Balanced bite: You get a satisfying mix of fats, fiber, and crunch, which helps keep hunger in check without feeling heavy.
Common Mistakes to Avoid
- Over-toasting the bread: If it’s too hard, the topping slides off and it’s tough to bite. Aim for crisp edges and a lightly toasted center.
- Using cold butter: Hard butter tears the bread and won’t spread evenly.
Let it soften to room temp.
- Thick radish slices: Thick slices taste harsh and overpower the herbs. Go thin for a cleaner, more elegant bite.
- Wet sprouts or radishes: Excess moisture makes the crostini soggy. Pat dry before assembling.
- Skipping seasoning: A pinch of flaky salt at the end makes everything pop.
Don’t forget a little pepper too.
Variations You Can Try
- Go tangy: Mix some soft goat cheese or cream cheese into the butter for extra tang and body.
- Citrus swap: Use lime or orange zest instead of lemon for a different aroma.
- Herb switch-up: Try tarragon for a hint of anise, basil for sweetness, or cilantro with a squeeze of lime.
- Heat lovers: Add a dash of Aleppo pepper, Calabrian chili paste, or chili oil to the butter.
- Seeded crunch: Sprinkle toasted sesame or pumpkin seeds over the top for texture.
- Gluten-free: Use your favorite gluten-free baguette or seed crackers and follow the same toppings.
- Vegan version: Swap in a high-quality vegan butter and use extra herbs and lemon to brighten the flavor.
FAQ
Can I make the herb butter in advance?
Yes. The herb butter actually improves after a few hours as the flavors meld. Make it up to 5 days ahead and keep it chilled.
Let it sit on the counter for 15–20 minutes before spreading.
What kind of radishes work best?
Classic red globe radishes are great for flavor and color. Watermelon radishes look stunning with their pink centers, and French breakfast radishes slice neatly and taste slightly milder. Whatever you choose, go for firm, fresh radishes.
How do I keep the crostini from getting soggy?
Toast the bread well and let it cool slightly before topping.
Make sure radishes and sprouts are dry. Assemble close to serving time and avoid stacking the finished crostini on top of each other.
Can I skip the garlic?
Absolutely. The butter still tastes lively with herbs and lemon.
If you’re sensitive to raw garlic, try rubbing a cut clove over the hot toast instead for a gentler flavor.
What if I don’t have sunflower sprouts?
Use other microgreens like pea shoots, arugula sprouts, or even a small handful of baby arugula torn into bite-size pieces. You’ll still get that fresh, green lift.
Do I need a mandoline for the radishes?
No, but it helps. A sharp knife works fine—just aim for very thin slices.
If your slices are thicker, use fewer per crostino to keep the flavor balanced.
Can I make this a meal?
Sure. Serve the crostini with a simple salad or a bowl of soup. You can also add a soft-boiled egg on the side or a few slices of smoked salmon for protein.
