5 Unconventional Foods You Should Be Grilling, According to Chefs

Your grill can do more than cook burgers and hot dogs. Chefs across the country are turning to unconventional grilling foods like watermelon, halloumi, avocado, and even cake — and the results are spectacular. This summer, your backyard grill can become a canvas for surprising flavors that will leave your guests asking for more.

Grilling has long been synonymous with meat-centric cookouts: steaks, burgers, sausages, and chicken. But the grill's dry heat and smoky kiss can transform a wide array of unexpected ingredients. From fruit to cheese to leafy greens, these unconventional grilling foods open up a new world of taste and texture.

The movement toward grilling beyond protein is driven by both curiosity and a desire for healthier, more diverse meals. Chefs emphasize that high heat caramelizes natural sugars in fruits, creates a crispy exterior on cheeses like halloumi, and infuses even delicate greens with a subtle smokiness that no oven can replicate.

Among the most touted unconventional grilling foods is watermelon. According to chefs, pressing thick slices onto a hot grate for two to three minutes per side caramelizes the sugars, resulting in a savory-sweet contrast that pairs beautifully with feta cheese and mint. Halloumi, a semi-hard cheese from Cyprus, holds its shape under extreme heat and develops a golden crust while remaining soft inside. Grilled avocado halves become buttery and warm, perfect for scooping with a spoon or mashing into guacamole. Romaine lettuce hearts, halved lengthwise and grilled for just a minute per side, gain a charred flavor that elevates a classic Caesar salad. For dessert, slices of pound cake or angel food cake become lightly toasted with grill marks, ready to be served with grilled fruit and ice cream.

The appeal of these unconventional grilling foods lies in the chemical reactions that occur under high heat. Sugars caramelize, proteins brown via the Maillard reaction, and moisture evaporates, concentrating flavors. The process is quick — typically under five minutes — making it an efficient way to add depth to meals.

Experts note that this trend isn't just a fad. As plant-based eating gains traction, grilling vegetables, cheeses, and fruits offers a satisfying alternative without sacrificing the grill experience. Food bloggers and home cooks are experimenting with everything from grilled pizza to grilled pineapple, and chefs predict that more unusual items like grilled iceberg lettuce or grilled watermelon steak will appear on restaurant menus nationwide.

Looking ahead, the grill may become as versatile as a stovetop. Expect to see more charred desserts, salty-sweet combinations, and unexpected ingredients earning a spot between the briquettes. The only limit is your imagination — and a willingness to let a little flame kiss something new.
