It’s this season’s take on my Blueberry Peach and Pistachio Crumble. Sweet, juicy strawberries and blueberries bubble beneath a buttery, golden crumble, while crunchy pistachios add the perfect nutty finish. It’s simple, comforting, and celebrates everything that’s good about summer fruit. I love serving a crumble like this when friends and family come over because it feels effortlessly elevated without keeping you in the kitchen all day. Pop it in the oven while everyone chats, then serve it warm with a scoop of vanilla ice cream for a dessert that always steals the show.
