• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 4–6

Ingredients

For the Steak & Marinade

• 1.2–1.5 pounds (550–700 g) flank steak or sirloin, sliced into strips
• 1/4 cup (60 ml) balsamic vinegar
• 3 tablespoons olive oil
• 2 tablespoons soy sauce
• 2 cloves garlic, minced
• 1 tablespoon honey or brown sugar
• 1 teaspoon Dijon mustard (optional)
• 1/2 teaspoon black pepper
• 1/2 teaspoon salt

For the Vegetables

• 2 cups broccoli florets
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 zucchini, sliced
• 1 red onion, sliced
• 2 tablespoons olive oil
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper

Instructions

1. Preheat the Oven: Preheat the oven to 425°F (220°C). Line a large sheet pan with parchment paper for easy cleanup.
2. Make the Marinade: In a medium bowl, whisk together the balsamic vinegar, olive oil, soy sauce, garlic, honey (or brown sugar), Dijon mustard, salt, and black pepper until well combined.
3. Marinate the Steak: Add the steak strips to the marinade and toss until evenly coated. Let sit for 10–15 minutes while you prepare the vegetables.
4. Prepare the Vegetables: Arrange the broccoli, bell peppers, zucchini, and red onion on the prepared sheet pan. Drizzle with olive oil and season with salt and pepper. Toss to coat evenly.
5. Arrange Everything: Spread the vegetables into an even layer. Add the marinated steak strips alongside or on top of the vegetables, making sure not to overcrowd the pan.
6. Roast: Bake for 20–25 minutes, stirring once halfway through cooking, until the vegetables are tender and the steak reaches your desired doneness.
7. Finish and Serve: If desired, drizzle with extra balsamic glaze or a splash of fresh balsamic vinegar before serving for an extra burst of flavor.

Recipe Notes

Pro Tip: For the best browning, pat your steak completely dry with paper towels before slicing it. Removing excess moisture helps the marinade cling to the meat and encourages better caramelization in the oven.
