Step 1: Roast the Vegetables

1. Preheat your oven to 425°F (220°C).
2. Toss the potatoes, broccoli, carrots, and bell pepper with olive oil, salt, pepper, and Italian seasoning. Spread evenly on a large baking sheet. Roast for 20–25 minutes, stirring halfway through, until tender and slightly caramelized.

Step 2: Cook the Steak

1. While the vegetables roast, season the steak cubes with salt, pepper, and smoked paprika.
2. Heat olive oil in a large cast-iron skillet over medium-high heat. Sear the steak cubes for 2–3 minutes on each side until browned and cooked to your desired doneness. Remove from heat and tent with foil to rest.

Step 3: Make the Garlic Butter

1. In the same skillet, reduce the heat to low and add the melted butter and minced garlic. Stir for 1–2 minutes until fragrant, then mix in the parsley.

Step 4: Assemble the Dish

1. Return the steak to the skillet and toss to coat with garlic butter.
2. Arrange the roasted vegetables around the steak and serve immediately.
