Preparing the Delmonico Steak
Before you even think about cooking, you need to properly prep your Delmonico steak to ensure it cooks to perfection.
Step 1: Bring the Steak to Room Temperature
Before cooking, allow your Delmonico steak to sit at room temperature for 30-45 minutes. This step is crucial because cooking a cold steak can lead to uneven cooking, leaving you with a steak that’s burnt on the outside but raw in the center.
Step 2: Seasoning Your Steak
Generously season the steaks with salt and pepper on both sides. If you want extra flavor, rub the steaks with minced garlic and a sprig or two of fresh rosemary. Let the seasoning sit for about 10-15 minutes to absorb into the meat.
Roasting the Vegetables
Perfectly roasted vegetables are the ideal side dish for your Delmonico steak. Here’s how to get them just right.
Step 1: Preheat the Oven
Set your oven to 400°F (200°C) to ensure the vegetables cook evenly and get a beautiful caramelization.
Step 2: Preparing the Vegetables
- Potatoes: Peel and cube the potatoes into bite-sized chunks.
- Carrots: Peel and cut them into sticks or rounds.
- Bell pepper and zucchini: Slice into even pieces.
- Drizzle the vegetables with olive oil, sprinkle with salt and pepper, and toss them well to ensure everything is coated evenly. You can also add a few sprigs of rosemary or thyme for added flavor.
Step 3: Roasting the Vegetables
- Place the prepared vegetables on a baking sheet, making sure they are spread out in a single layer.
- Roast for 25-30 minutes, flipping them halfway through. The vegetables should be golden and fork-tender when done.
Cooking the Perfect Delmonico Steak
Now that your vegetables are roasting, it’s time to focus on cooking your Delmonico steak to perfection.
Option 1: Grilling the Delmonico Steak

- Preheat the Grill: Heat your grill to medium-high, ensuring it’s hot before placing the steaks on it.
- Grilling Time: Grill the steaks for 4-5 minutes per side for a perfect medium-rare steak. Adjust the time for more or less doneness.
- Finishing Touch: Add a tablespoon of butter and a sprig of fresh rosemary during the last minute of grilling to enhance flavor and juiciness.
Option 2: Pan-Seared Delmonico Steak
- Heat the Pan: Use a cast-iron skillet and heat it on medium-high. Add olive oil.
- Cooking the Steak: Sear the steaks for 4-5 minutes on each side until a deep, golden-brown crust forms.
- Adding Butter: In the last minute of cooking, add butter, a clove of garlic, and a few sprigs of fresh rosemary to the pan and baste the steak with the melted butter.
Step 3: Checking Doneness
To ensure your steak is cooked perfectly, use a meat thermometer. Here’s a quick guide to steak temperatures:
- Rare: 120-125°F (49-52°C)
- Medium-Rare: 130-135°F (54-57°C)
- Medium: 140-145°F (60-63°C)
- Medium-Well: 150-155°F (65-68°C)
- Well Done: 160°F (71°C) and above.
Step 4: Resting the Steak
Once your steak has reached the desired doneness, let it rest for 5-10 minutes before cutting into it. This allows the juices to redistribute throughout the meat, ensuring a moist and tender steak.
Serving Your Delmonico Steak with Roasted Vegetables
Now that everything is cooked, it’s time to plate up and enjoy.
Step 1: Slice the Steak
After resting, slice your steak against the grain for maximum tenderness.
Step 2: Plate the Roasted Vegetables
Arrange the roasted vegetables around the steak, creating a visually appealing and well-balanced plate. The contrast of textures—crispy vegetables and juicy steak—will make each bite a delight.
Step 3: Garnish
For an extra touch, garnish the plate with a sprig of fresh parsley or thyme, adding a pop of color and freshness to the dish.
Common Mistakes to Avoid When Cooking Delmonico Steak with Roasted Vegetables
Even experienced cooks can make mistakes when preparing a meal like this, but avoiding the following will help you ensure success:
Mistake 1: Overcooking the Steak
To avoid overcooking, use a meat thermometer to check for doneness. Remember that the steak will continue to cook a little as it rests, so pull it off the heat just before it reaches your desired temperature.
Mistake 2: Undercooking the Vegetables
Roasted vegetables need time to get crispy and golden. If they’re undercooked, they’ll lack flavor and texture. Always ensure that they’re tender when you remove them from the oven.
Mistake 3: Not Letting the Steak Rest
Letting your steak rest is crucial. If you cut into it right away, the juices will spill out, leaving the meat dry. Resting helps retain all the flavor and moisture.
