How To Cook A Delmonico Steak In The Oven

You want a fantastic steak dinner without the fuss of grilling. Learning how to cook a Delmonico steak in the oven is a simple and reliable method for a perfect meal at home.

This cut, known for its rich flavor and tenderness, is ideal for oven cooking. With a good sear and gentle oven finish, you get a juicy, restaurant-quality result. This guide walks you through each step, from choosing your steak to serving it.

This method uses a two-step process: searing and roasting. It ensures a beautiful crust and even doneness. You only need a few basic tools: a heavy oven-safe skillet, tongs, a meat thermometer, and simple seasonings.

What is a Delmonico Steak?

The name “Delmonico” can refer to a specific cut or a style of preparation from the historic Delmonico’s Restaurant. Today, it commonly means a boneless ribeye, cut thick. It’s well-marbled, which means it has fat running through it. This fat melts during cooking, basting the steak from the inside for incredible flavor and a buttery texture.

If your butcher doesn’t label a steak “Delmonico,” ask for a thick-cut, boneless ribeye. A thickness of 1.5 to 2 inches is perfect for this oven method.

Choosing the Right Steak

Picking a good steak is the first step to success. Look for these things:

Marbling: Seek fine white streaks of fat throughout the red meat. More marbling usually means more flavor.
Color: The meat should be a bright, cherry-red color.
Thickness: Aim for at least 1.5 inches thick. This allows time to develop a crust in the pan before finishing in the oven without overcooking.
Grade: USDA Choice or Prime are excellent choices. Prime has the most marbling, but Choice offers great quality for the price.

Essential Tools and Ingredients

You don’t need fancy equipment. Here’s your checklist:

Oven-safe skillet: Cast iron or heavy stainless steel is best. It must be able to go from the stovetop to the oven.
Tongs: For turning the steak without piercing it.
Instant-read meat thermometer: This is non-negotiable for perfect doneness.
Your steak: 1.5 to 2 inches thick.
High-heat oil: Avocado oil, grapeseed oil, or refined olive oil.
Kosher salt and coarse black pepper: The fundamental seasonings.
Butter and aromatics (optional): A few tablespoons of butter with fresh thyme or rosemary and garlic cloves for basting.

Preparing Your Steak

Proper preparation makes a big difference. Follow these steps about 30-60 minutes before cooking.

Pat Dry: Use paper towels to thoroughly dry the entire surface of the steak. This is crucial for getting a sear, not a steam.
Season Generously: Coat all sides liberally with kosher salt and black pepper. Don’t be shy; some will fall off during cooking.
Bring to Room Temperature: Let the seasoned steak sit on a plate on your counter. This helps it cook more evenly. It should not be cold in the center when it hits the pan.

Step-by-Step Cooking Instructions

Now for the main event. Preheat your oven to 400°F (200°C). This moderate temperature finishes the steak gently.

Step 1: Preheat Your Skillet

Place your oven-safe skillet on the stovetop over medium-high heat. Let it get hot for about 5 minutes. You want it very hot before adding any oil. A drop of water should skitter and evaporate instantly.

Step 2: Sear the Steak

Add just enough high-heat oil to coat the bottom of the hot skillet. Carefully place the steak in the center. It should sizzle loudly. Do not move it for 2-3 minutes. This allows a deep brown crust to form. Use your tongs to flip the steak and sear the other side for another 2-3 minutes. Sear the edges for about 30 seconds each if possible.

Step 3: Add Butter and Aromatics (Optional)

If you’re using them, reduce the heat to medium. Add butter, garlic, and herbs to the skillet beside the steak. As the butter melts, tilt the pan and use a spoon to continuously baste the top of the steak with the foaming butter for about a minute. This adds incredible flavor.

Step 4: Finish in the Oven

Immediately transfer the entire skillet to your preheated oven. The carryover heat from the sear and the oven’s ambient heat will finish cooking the center.

Step 5: Check for Doneness

Cook time in the oven varies. For a 1.5-inch steak, check after 5-6 minutes. The only reliable way to know is by using a meat thermometer. Insert it horizontally into the thickest part of the steak.

Rare: 120-125°F (49-52°C)
Medium Rare: 130-135°F (54-57°C) – This is the recommended temperature for this cut.
Medium: 140-145°F (60-63°C)
Medium Well: 150-155°F (66-68°C)

Remember, the temperature will rise about 5 degrees as the steak rests.

Step 6: The Critical Rest

This might be the hardest step, but it’s essential. Use tongs to move the steak from the skillet to a cutting board or warm plate. Loosely tent it with foil. Let it rest for at least 10 minutes. This allows the juices, which have been driven to the center by the heat, to redistribute throughout the entire steak. If you cut it to soon, those precious juices will end up on your plate, not in the meat.

Tips for the Best Results

Don’t overcrowd the pan. Cook one steak at a time, or use two skillets if needed.
Always preheat your skillet thoroughly. A hot pan is key to the Maillard reaction, which creates flavor.
Resist the urge to press down on the steak with your spatula. Your squeezing out the juices you want to keep inside.
Let your steak rest fully. Those 10 minutes are when the magic of juiciness happens.
Slice against the grain before serving. Look for the lines running through the meat and cut perpendicular to them. This shortens the muscle fibers, making each bite more tender.

Common Mistakes to Avoid

Even small errors can affect your steak. Here’s what to watch out for:

Using a cold steak: A cold center leads to uneven cooking.
Not drying the surface: Moisture creates steam, preventing a good sear.
Moving the steak too soon: Let the sear develop without disturbing it.
Skipping the thermometer: Guessing doneness often leads to overcooking.
Skipping the rest: Cutting immediately causes a dry steak.
Using extra virgin olive oil for searing: It has a low smoke point and will burn. Save it for finishing.

Serving Suggestions

A great steak deserves simple sides that complement it, not compete. Here are some classic pairings:

Potatoes: Creamy mashed potatoes, crispy roasted potatoes, or a simple baked potato.
Vegetables: Sautéed mushrooms, garlic green beans, roasted asparagus, or a crisp salad.
Sauces (optional): A classic Béarnaise, a creamy peppercorn sauce, or a simple compound butter melting on top.
Bread: A warm, crusty roll to soak up any juices.

Storing and Reheating Leftovers

Leftover steak is a treat. Store it properly to maintain quality.

Let leftover steak cool completely. Wrap it tightly in plastic wrap or aluminum foil, or place it in an airtight container. It will keep in the refrigerator for 3-4 days.

The best way to reheat steak is gently. Avoid the microwave, which can make it tough and rubbery.

Let the steak come to room temperature for 20 minutes.
Preheat your oven to 250°F (120°C).
Place the steak on a wire rack set over a baking sheet. This allows air to circulate.
Warm it for 20-30 minutes, just until it’s heated through. You can also use a skillet on very low heat for a few minutes per side.

Frequently Asked Questions (FAQ)

What is a Delmonico steak?

It’s typically a thick-cut, boneless ribeye steak known for its excellent marbling and rich, beefy flavor. The name comes from a famous 19th-century restaurant.

Can I cook a frozen Delmonico steak in the oven?

It’s not recommended for this method. For best results, thaw the steak completely in the refrigerator first. Cooking from frozen will give you an uneven sear and overcooked exterior before the center is done.

What temperature should the oven be for Delmonico steak?

A moderate oven temperature of 400°F (200°C) works perfectly. It’s hot enough to finish cooking the steak without burning the crust you created on the stovetop.

How long to cook Delmonico steak in oven after searing?

For a 1.5-inch steak, start checking at 5-6 minutes in a 400°F oven. Always use a meat thermometer for accuracy, as thickness and starting temperature vary.

Do I need to flip the steak in the oven?

No, you do not. The oven’s ambient heat cooks it evenly from all sides after the initial sear on both sides in the skillet. Flipping it is unnecessary and can disrupt the cooking process.

Kosher salt and freshly ground black pepper are all you need. Their simple flavor enhances the natural taste of the beef without hiding it. Apply them generously before cooking.

Why did my steak turn out tough?

A few factors can cause toughness: overcooking past your desired doneness, not slicing against the grain, or using a lower-quality cut with less marbling. Using a thermometer and proper slicing technique solves most issues.

Cooking a Delmonico steak in the oven is a straightforward technique that yields impressive results. The combination of a hot sear and gentle oven finish gives you control over the doneness and creates a fantastic texture.
