Celebrated for its striking colors and effortless simplicity, an Heirloom Tomato Caprese Salad with Basil Oil is the ultimate expression of summer produce. Thick slices of juicy, jewel-toned heirloom tomatoes are layered with creamy fresh mozzarella di bufala, seasoned with flaky sea salt, and drizzled with a bright green, homemade basil infused oil alongside aged balsamic glaze.
The secret to a restaurant-worthy Caprese salad is Blanching Fresh Basil Leaves in Boiling Water for 10 Seconds Before Blending with Extra Virgin Olive Oil. Flash-blanching sets the green chlorophyll in the basil, giving your basil oil an emerald color that stays bright without turning dull or brown.

Step-by-Step Instructions
1.Blanch & Shock the Basil:3 min.
Bring a small pot of water to a boil and prepare an ice bath. Submerge 1 cup of tightly packed fresh basil leaves in the boiling water for just 10 seconds. Immediately transfer with a slotted spoon into the ice bath to shock and lock in the bright green color.
2.Blend & Strain the Emerald Basil Oil:3 min.
Squeeze all water out of the blanched basil using paper towels. Place the blanched basil into a blender or small food processor with ½ cup high-quality extra virgin olive oil and a pinch of salt. Blend on high for 1 to 2 minutes until completely smooth. Strain through a fine-mesh sieve or cheesecloth into a small pitcher.
3.Slice & Season the Tomatoes:5 min.
Slice 2 lbs of mixed heirloom tomatoes into thick ⅓-inch rounds. Arrange the tomato slices in a single layer on paper towels and sprinkle lightly with flaky sea salt. Let sit for 3 minutes to draw out excess liquid and concentrate their natural sweetness.
4.Layer & Plate:5 min.
On a large serving platter, arrange the heirloom tomato slices and 8 oz sliced fresh mozzarella in an overlapping pattern (or stack them into elegant individual towers).
5.Drizzle & Garnish:2 min.
Generously spoon the bright green basil oil over the layered tomatoes and mozzarella. Drizzle with 1 to 2 tablespoons aged balsamic glaze, garnish with fresh unblanched basil leaves, and finish with freshly cracked black pepper and flaky sea salt. Serve immediately!
Expert Tips for Success
- Serve at Room Temperature: Never serve Caprese cold straight out of the fridge! Cold temperatures mute the sweetness of ripe tomatoes and firm up fresh mozzarella. Let ingredients sit at room temperature for 20 minutes before serving.
- Use Flaky Sea Salt (Maldon): Coarse, flaky sea salt gives a delightful crunchy pop that enhances the natural sweetness of the tomatoes better than fine table salt.
- Store Extra Basil Oil: Leftover homemade basil oil keeps well in a sealed glass jar in the fridge for up to 5 days—drizzle it over grilled sourdough bread, roasted vegetables, or pasta!
