This easy beef kebab recipe combines a simple marinade with the convenience of sheet pan cooking. By marinating the beef, you infuse it with flavor and tenderness, while roasting it alongside fresh vegetables ensures a complete meal with minimal cleanup.
In a large bowl, combine olive oil, minced garlic, cumin, smoked paprika, salt, and black pepper. Mix well to create the marinade.
Add the beef cubes to the marinade, tossing to coat evenly. Cover the bowl and let it marinate in the refrigerator for at least 30 minutes, or up to 4 hours for more flavor.
Preheat the oven to 425°F (220°C).
While the oven preheats, prepare the vegetables. Cut the bell peppers, zucchini, and onion into chunks.
On a large sheet pan, spread the marinated beef and vegetables in a single layer. Ensure they are not overcrowded to allow for even roasting.
Roast in the preheated oven for 20-25 minutes, or until the beef reaches your desired level of doneness and the vegetables are tender and lightly charred.
Remove from the oven and let rest for a few minutes. Garnish with chopped fresh parsley before serving.
