Ingredients

• 1/2 pound fresh strawberries, stems removed and cut in half
• 1 pound fresh strawberries, stems removed and diced (for salsa)
• 2 tablespoons water
• 2 tablespoons ketchup
• 2 teaspoons packed light brown sugar
• 2 teaspoons fresh basil, finely chopped, plus 2 additional tablespoons
• 2 teaspoons white wine vinegar, plus 2 additional tablespoons
• 2 teaspoons fresh garlic, minced (divided use)
• 1/8 teaspoon ground white pepper
• 1 1/4 teaspoons kosher salt, plus 1/8 teaspoon (divided use)
• 1/4 teaspoon freshly cracked black pepper
• 1 1/4 to 1 1/2 pounds beef flank steak
• 1 English cucumber, peeled, seeded, and diced
• 2 tablespoons red onion, finely diced
• Extra fresh basil leaves for garnish

Instructions

1. Heat your oven to 400°F and line a rimmed baking sheet with parchment paper. Arrange the halved strawberries in a single layer on the prepared sheet.
2. Roast the strawberries for about 20 minutes until they’re beautifully caramelized, fragrant, and tender. You’ll see their juices bubbling – that’s liquid gold right there!
3. Transfer the roasted strawberries and all their precious juices to a small saucepan. Add water, ketchup, brown sugar, 2 teaspoons basil, 2 teaspoons vinegar, 1 teaspoon garlic, white pepper, and 1/8 teaspoon salt. Bring this mixture to a rolling boil, then reduce heat to medium-low and let it simmer for 20 minutes, stirring occasionally.
4. Let the sauce cool slightly, then blend until completely smooth using a food processor or blender. This creates your gorgeous strawberry barbecue glaze!
5. Fire up your grill to medium-high heat (around 375-400°F) and oil those grates well. Season your flank steak generously with 1/4 teaspoon salt and the black pepper.
6. Grill the steak covered for 10 minutes, then flip and start brushing with your strawberry sauce. Continue cooking for about 10 more minutes, basting with sauce every 3 minutes. You’re looking for an internal temperature of 130°F for medium-rare or 140°F for medium.
7. Remove the steak to a cutting board, tent loosely with foil, and let it rest for 10 minutes. This allows the juices to redistribute and the temperature to rise to a perfect 135°F (medium-rare) or 145°F (medium).
8. While the steak rests, make your fresh salsa by combining the diced strawberries, cucumber, red onion, remaining 2 tablespoons each of basil and vinegar, plus the remaining teaspoon each of garlic and salt. This can be made up to 4 hours ahead and chilled.
9. Slice the steak thinly against the grain and serve topped with the fresh strawberry salsa and extra basil leaves.

Tips & Variations

Pro Tips: For the best results, choose strawberries that are ripe but still firm – they’ll hold their shape better during roasting and won’t make your salsa watery. Always slice flank steak against the grain for maximum tenderness, and don’t skip the resting time as it makes a huge difference in juiciness. If you don’t have white wine vinegar, regular white vinegar or even apple cider vinegar works beautifully as a substitute.
