Cast-Iron Seared New York Strip with Autumn Root Vegetables.

As autumn temperatures drop, evening meals should provide steady warmth alongside solid nutrition. This cast-iron steak dinner pairs lean beef with slow-burning complex carbohydrates and roasted vegetables, creating a balanced meal that promotes sustained energy without heavy additives. The New York strip steak supplies a high concentration of dietary protein, zinc, and iron to support muscle repair and red blood cell production. This is complemented by charred Brussels sprouts, which deliver dietary fiber and vitamins that assist the body’s natural metabolic processes. Finally, roasted sweet potatoes offer a nutrient-dense carbohydrate source rich in beta-carotene and potassium, stabilizing evening blood sugar levels and replenishing muscle energy.

Time and Servings

Serving Size: 2 Servings

Ingredients

Steak

• 2 New York strip steaks (approx. 10–12 oz each, brought to room temperature)
• 1 tbsp avocado oil
• 1 tsp coarse sea salt
• 1 tsp freshly cracked black pepper
• 2 cloves garlic, crushed
• 2 fresh rosemary or thyme sprigs

Vegetables

• 1 lb fresh Brussels sprouts, trimmed and halved lengthwise
• 1 large sweet potato, diced into 1/2-inch cubes
• 1.5 tbsp extra virgin olive oil
• 1/2 tsp garlic powder
• Fine sea salt and black pepper to taste

Cooking Steps

Step 1: Roast the Vegetables

Preheat your oven to 400°F (200°C). In a large bowl, toss the cubed sweet potatoes and halved Brussels sprouts with olive oil, garlic powder, salt, and pepper. Spread evenly across a large baking sheet, placing the Brussels sprouts cut-side down to ensure deep caramelization. Roast for 20 to 25 minutes until tender and crisped at the edges.

Step 2: Sear the Steaks

Heat a heavy cast-iron skillet over high heat until hot. Pat the steaks dry with paper towels and season generously with sea salt and cracked pepper. Add avocado oil to the pan, then lay the steaks in carefully. Sear without moving for 3 to 4 minutes to establish a dark, even crust.

Step 3: Finish with Aromatics

Flip the steaks and cook for another 3 to 4 minutes (aiming for an internal temperature of 130°F–135°F / 54°C–57°C for medium-rare). In the final minute, add the crushed garlic cloves and herb sprigs to the skillet.

Step 4: Rest and Serve

Transfer the steaks to a cutting board and let rest for 5 to 7 minutes before slicing against the grain. Serve alongside the warm roasted vegetables.
