Step-by-Step Instructions
Phase 1: Preparing Your Oven and Grapes (5 Minutes)
Step 1: Preheat your oven to 400°F and position the rack in the center. This temperature is hot enough to caramelize the grape sugars without burning them.
Step 2: Line a rimmed baking sheet with parchment paper. The parchment prevents sticking and makes cleanup easier since grape juices can get sticky.
Step 3: Rinse 2 cups of red grapes under cold water and pat them completely dry with paper towels. Wet grapes won’t roast properly—they’ll steam instead.
Step 4: Remove the grapes from their stems and spread them in a single layer on your prepared baking sheet. Leave space between each grape so they roast evenly rather than steaming.
Phase 2: Seasoning and Roasting (25 Minutes)
Step 5: Drizzle the grapes with 2 tablespoons of olive oil and toss gently with your hands until every grape glistens. The oil helps them caramelize and prevents shriveling.
Step 6: Scatter 3 fresh thyme sprigs over the grapes, then drizzle with 1 tablespoon of honey and 1 teaspoon of balsamic vinegar. The honey enhances their natural sweetness while the vinegar adds depth.
Step 7: Sprinkle with ¼ teaspoon salt and ⅛ teaspoon black pepper. Season now because the flavors intensify during roasting.
Step 8: Roast for 20-25 minutes until the grapes are blistered, slightly shriveled, and sitting in their own syrupy juices. Some will burst—that’s perfect. Remove and let cool for 10 minutes while you prepare the other components.
Phase 3: Creating the Whipped Feta (10 Minutes)
Step 9: Add 8 ounces of feta cheese (broken into chunks), 4 ounces of softened cream cheese, 3 tablespoons of Greek yogurt, 1 tablespoon of lemon juice, and 1 small minced garlic clove to your food processor.
Step 10: Blend on high speed for 2-3 minutes, stopping to scrape down the sides halfway through. You’re looking for a texture like thick frosting—completely smooth with no lumps.
Step 11: Add 2 tablespoons of chopped fresh dill and pulse 3-4 times just to incorporate. Overmixing at this stage will turn the dill brown and muddy the color.
Step 12: Taste and adjust seasoning. Feta varies in saltiness, so you might want a pinch more lemon juice if yours is particularly salty.
Phase 4: Making the Crostini (8 Minutes)
Step 13: Slice your baguette on a diagonal into ¼-inch thick slices. You should get about 16-20 slices. Diagonal cuts give you more surface area for toppings.
Step 14: Arrange the bread slices on a clean baking sheet and brush the tops with 3 tablespoons of olive oil. Use a pastry brush for even coverage—you want every bit golden.
Step 15: Bake at 400°F for 5-7 minutes until the edges are golden brown and the centers are crispy. Watch carefully after 5 minutes because they can burn quickly.
Step 16: Remove from the oven and let cool for 2 minutes on the pan. They’ll continue crisping as they cool.
Phase 5: Assembly (3 Minutes)
Step 17: Spread a generous tablespoon of the whipped feta mixture onto each crostini. Use the back of a spoon to create swoops and peaks—this adds visual appeal.
Step 18: Top each crostini with 3-4 roasted grapes, making sure to drizzle some of the pan syrup over everything. That syrup is liquid gold.
Step 19: Finish with a sprinkle of flaky sea salt and a few fresh thyme leaves. Serve immediately while the bread is still warm and crispy.
Chef’s Notes
Balance is Everything: The salty feta, sweet roasted grapes, and tangy yogurt create a perfect flavor triangle that keeps each bite interesting.
Room Temperature Matters: Let your cream cheese sit out for 30 minutes before blending. Cold cream cheese creates lumps that won’t blend out.
Grape Selection: Choose firm, sweet red grapes. Mushy or overripe grapes turn to mush when roasted instead of getting jammy.
Make-Ahead Strategy: Prepare the roasted grapes and whipped feta 2 days ahead. Toast the bread 30 minutes before serving and assemble just before guests arrive.

Variations to Try
Blue Cheese Twist: Swap half the feta for Gorgonzola or Roquefort for a more pungent, earthy flavor that pairs beautifully with the sweet grapes.
Holiday Cranberry Version: Replace the grapes with fresh cranberries and add orange zest to the whipped feta. This pairs wonderfully with our festive cranberry salsa for a complete holiday appetizer spread.
Warm Spice Addition: Add ½ teaspoon of cinnamon and ¼ teaspoon of cardamom to your grapes before roasting for a Middle Eastern-inspired flavor profile.
Dessert Crostini: Drizzle the finished crostini with warm apple cider fondue instead of the pan syrup for a sweet-savory dessert option that surprises everyone.
Storage & Reheating
Store the whipped feta in an airtight container in the refrigerator for up to 5 days. Bring to room temperature 30 minutes before serving—cold feta loses its creamy texture.
Keep roasted grapes refrigerated in their pan juices for up to 1 week. Warm them gently in a 300°F oven for 5 minutes before serving.
Store unbaked bread slices in a zip-top bag at room temperature for 2 days. Toast them fresh right before assembling.
Never assemble crostini more than 15 minutes ahead—the moisture from the toppings will make the bread soggy.
Troubleshooting
Problem: My whipped feta is grainy and lumpy.
Solution: Your cream cheese was too cold. Let it sit at room temperature for 30 minutes and reblend. Add 1 tablespoon more yogurt if needed to smooth it out.
Problem: The grapes didn’t get jammy—they just shriveled.
Solution: Your oven wasn’t hot enough or you crowded the pan. Grapes need space and 400°F+ heat to caramelize properly. Try roasting 5 minutes longer.
Problem: My crostini burned on the edges but stayed soft in the middle.
Solution: You sliced the bread too thick. Aim for ¼-inch slices and rotate the pan halfway through baking for even browning.
Problem: The feta spread is too salty.
Solution: Feta brands vary wildly in salt content. Balance it with 1-2 tablespoons more Greek yogurt and an extra squeeze of lemon juice.
Problem: The assembled crostini got soggy within minutes.
Solution: Make sure your grapes cooled completely before assembly. Hot grapes release steam that soaks the bread. Also, toast your bread until deeply golden—pale toast absorbs moisture faster.

Success Secrets
1. Choose block feta over crumbled. Pre-crumbled feta contains anti-caking agents that prevent smooth blending and create a grainy texture.
2. Roast your grapes until some burst completely. Those burst grapes create the syrupy pan sauce that ties everything together.
3. Cut your baguette on a 45-degree angle for larger slices with more surface area. This gives you more space for toppings and looks more elegant.
4. Bring every component to room temperature before assembling. Cold feta is stiff and hard to spread, and cold grapes mute the flavors.
5. Don’t skip the final flaky salt. That burst of salinity against the sweet grapes creates the addictive contrast that makes these crostini disappear from the plate.
