Cilantro Lime Lean Beef Sheet-Pan Dinner with Zucchini

Sheet-pan meals are at their best when minimal prep yields bold, distinct flavors. This recipe relies on a brisk chili-lime mixture whisked together and tossed over cubed sirloin and sliced zucchini before everything hits a hot oven. As the meat cooks through, the zucchini softens around the edges, catching the pan juices for an easy weeknight supper.
Why this one works
- Everything cooks simultaneously on a single rimmed baking sheet for quick cleanup.
- A three-ingredient seasoning blend coats both the meat and vegetables evenly.
- Lean sirloin cooks quickly when cut into bite-sized cubes.
- Fresh chopped cilantro adds a bright, herbal contrast just before plating.

What you’ll need
- 1 lb (450g) lean beef sirloin, cubed Cut into uniform, bite-sized cubes so the meat roasts evenly without drying out.
- 2 medium (300g) zucchini, sliced into half-moons Slice into medium-thick half-moons to keep them tender-crisp during the baking time.
- 1/4 cup (60ml) fresh cilantro, chopped Added fresh at the end to maintain its vibrant color and herbaceous aroma.
- 2 tablespoons (30ml) olive oil Helps the chili powder adhere and promotes gentle browning on the baking sheet.
- 1 tablespoon (15ml) lime juice Provides acidity to balance the savory beef and earthy chili powder.
