If you’re wondering how long to cook sirloin steak in oven, you’re in the right place. This method is fantastic for a hands-off approach or when you want to cook multiple steaks evenly without fussing over a grill.
Oven-cooked sirloin can be just as good as grilled or pan-seared. The key is understanding a few simple steps. We’ll cover everything from choosing your steak to getting that perfect finish.
You’ll learn the timing for different doneness levels. We’ll also talk about essential preparation and finishing techniques. Let’s get started.
How Long To Cook Sirloin Steak In Oven
The direct answer is: it depends on your steak’s thickness and your desired doneness. A typical 1-inch thick sirloin steak cooked in a 400°F (200°C) oven will take about 10-15 minutes for medium-rare.
But that’s just the oven time. For the best results, most methods involve a two-step process: searing first, then finishing in the oven. This gives you a beautiful crust and even cooking throughout.
Here is a general timing guide for a 1-inch thick sirloin steak, after searing, in a 400°F oven:
- Rare (120-125°F internal): 3-5 minutes
- Medium-Rare (130-135°F internal): 6-9 minutes
- Medium (140-145°F internal): 10-12 minutes
- Medium-Well (150-155°F internal): 13-15 minutes
- Well-Done (160°F+ internal): 16+ minutes (not recommended for sirloin)
Always use a meat thermometer for accuracy. Visual cues and timing are just estimates.
Choosing the Right Sirloin Steak
Not all sirloin steaks are created equal. Picking a good one is the first step to a great meal.
- Cut: Look for “top sirloin” or “center-cut sirloin.” These are the most tender parts of the sirloin. Bottom sirloin can be good to but might be slightly less tender.
- Thickness: Aim for steaks that are at least 1 inch thick. Thinner steaks (like 1/2 inch) are very hard to cook properly in the oven without overcooking. A 1.5-inch steak is even better for achieving a nice crust and juicy interior.
- Marbling: Look for thin white streaks of fat within the meat. This marbling melts during cooking, basting the steak from the inside and adding flavor and juiciness.
- Color: The steak should be a bright, cherry-red color. Avoid any steaks that look grayish or have brown spots.
Essential Tools You’ll Need
Gathering your tools before you start makes the process smooth.
- A heavy, oven-safe skillet (cast iron or stainless steel is perfect).
- Meat thermometer (instant-read or leave-in probe type).
- Tongs (never use a fork, it pierces the meat and releases juices).
- A small bowl for mixing oil and seasonings.
- A cutting board for resting the steak.
Preparing Your Steak for the Oven
Proper preparation is non-negotiable. Skipping these steps can lead to a tough, bland steak.
Step 1: Bring the Steak to Room Temperature
Take the steak out of the refrigerator at least 30-40 minutes before cooking. This allows it to warm up slightly. A cold steak straight from the fridge will cook unevenly, leaving you with a overcooked outside and a cold center.
Step 2: Pat it Dry
Use paper towels to pat the steak completely dry on all sides. Moisture is the enemy of a good sear. A wet steak will steam instead of sear, resulting in a gray, unappealing exterior.
Step 3: Season Generously
Season all sides of the steak liberally with kosher salt and freshly ground black pepper. You can add other dry seasonings like garlic powder, onion powder, or smoked paprika if you like. Do this right before cooking, as salting too far in advance can draw out moisture if left for hours.
Drizzle or brush a light coat of a high-heat oil (like avocado, canola, or vegetable oil) on the steak. This helps the seasoning stick and promotes browning.
The Two Best Oven Cooking Methods
Here are the two most reliable methods for cooking sirloin steak in the oven. The first is the most common and recommended.
Method 1: Sear First, Then Bake (Recommended)
This is the classic restaurant technique for a reason. It gives you maximum flavor and texture.
- Preheat your oven to 400°F (200°C). Place your oven-safe skillet on the stovetop over medium-high heat. Let it get very hot for a few minutes.
- Add a small amount of high-heat oil to the hot skillet. Carefully place your seasoned steak in the pan. It should sizzle immediately.
- Sear the steak for 2-3 minutes per side, without moving it, until a deep brown crust forms. If your steak has a fat cap, sear that edge for 30-60 seconds too.
- Immediately transfer the entire skillet to the preheated oven. Use your meat thermometer to check the internal temperature after the minimum time listed in the guide above.
- Remove the steak from the oven when it’s about 5 degrees below your target temperature (it will rise during resting). Use tongs to move the steak to a cutting board.
Method 2: Reverse Sear (For Thicker Steaks)
This method is excellent for steaks 1.5 inches or thicker. It involves a low oven first, then a quick sear at the end.
- Preheat your oven to a low temperature, around 250°F (120°C). Place a wire rack on a baking sheet.
- Season your steak and place it on the rack. Bake until the internal temperature is about 15-20 degrees below your final target (e.g., 110°F for medium-rare). This can take 20-30 minutes for a thick steak.
- Heat your skillet on the stovetop over high heat until screaming hot. Add oil.
- Sear the low-temperature steak for 60-90 seconds per side to develop a perfect crust. Because the inside is already warm, this happens fast.
The Critical Resting Period
Do not skip this step! As soon as the steak comes out of the oven, transfer it to a cutting board. Loosely tent it with a piece of aluminum foil. Let it rest for at least 5-10 minutes.
Why? The heat from cooking causes the juices to rush to the center of the steak. Resting allows those juices to redistribute throughout the entire piece of meat. If you cut into it immediately, all those flavorful juices will end up on your plate, not in your steak, making it dry.
Checking for Doneness: The Thermometer is Key
Guessing doneness by touch or look is unreliable. A meat thermometer is your best friend. Here are the USDA-recommended safe internal temperatures for beef steaks, adjusted for carryover cooking:
- Rare: 120-125°F (Remove from oven at 115-120°F)
- Medium-Rare: 130-135°F (Remove from oven at 125-130°F)
- Medium: 140-145°F (Remove from oven at 135-140°F)
- Medium-Well: 150-155°F (Remove from oven at 145-150°F)
- Well-Done: 160°F+ (Remove from oven at 155°F+)
Insert the thermometer probe into the thickest part of the steak, sideways, aiming for the center. Avoid touching bone or fat.
Tips for Extra Flavor and Juiciness
- Butter Basting: During the last minute of searing, add a couple tablespoons of butter, some garlic cloves, and fresh herbs (like thyme or rosemary) to the skillet. Tilt the pan and spoon the melted butter continuously over the steak before transferring it to the oven.
- Dry Brine: For deeper seasoning, pat the steak dry and season it with salt up to 24 hours in advance. Leave it uncovered on a rack in the fridge. This draws out moisture, which then dissolves the salt and is reabsorbed, seasoning the meat deeply and improving the crust.
- Simple Marinades: A quick 30-60 minute marinade in olive oil, acid (like lemon juice or vinegar), and herbs can add nice flavor. Don’t over-marinate, as the acid can start to break down the texture of the meat.
Common Mistakes to Avoid
Even small errors can affect your final result. Here’s what to watch out for.
- Using a thin, non-oven-safe pan: It won’t hold heat well for the sear and can’t go in the oven.
- Not preheating the skillet: A hot pan is essential for a proper sear. Give it time to heat up.
- Moving the steak too soon: Let it sear undisturbed to form that crust. If it sticks, it’s not ready to flip.
- Skipping the rest: We mentioned it before, but it’s that important. Let the steak rest.
- Overcrowding the pan: If cooking multiple steaks, use a large pan or cook in batches. Crowding creates steam.
Serving Your Perfect Oven-Cooked Sirloin
After resting, slice the steak against the grain. This means cut perpendicular to the long muscle fibers you can see. This makes each bite much more tender to chew.
Serve it with your favorite sides. Classic pairings include roasted potatoes, a simple green salad, sautéed mushrooms, grilled asparagus, or creamy mashed potatoes. A pat of compound butter melting on top is always a welcome addition.
FAQ Section
How long does it take to cook a sirloin steak in the oven at 350?
At a lower temperature like 350°F (175°C), cooking will take longer. For a 1-inch steak (after searing), expect 15-20 minutes for medium-rare. Always use a thermometer, as lower heat means less margin for error in timing.
Can you cook sirloin steak in the oven without searing first?
You can, but you won’t get the flavorful, caramelized crust (the Maillard reaction) that makes steak so good. It will taste more like roasted beef. For best results, always sear first or use the reverse sear method.
What is the best temperature to cook steak in the oven?
A high temperature, between 400°F and 450°F (200°C-230°C), is best for the “sear then bake” method. For the reverse sear, a low temperature of 250°F-275°F (120°C-135°C) is used for the initial slow cook.
How do you keep sirloin steak from drying out in the oven?
Use a thick cut (at least 1 inch), don’t overcook it (use a thermometer), let it come to room temperature before cooking, and always rest it after. These steps ensure the juices stay in the meat.
Should you cover steak when baking it in the oven?
No, you should not cover it. Covering it will create steam and prevent the surface from drying out and browning properly. You want the hot, dry air of the oven to surround the steak.
How long to cook a 2 inch sirloin steak in the oven?
A 2-inch steak is a candidate for the reverse sear. Bake at 250°F until the internal temp is ~110°F for medium-rare (this may take 40-50 minutes), then sear for 90 seconds per side. For the standard method, sear for 3-4 minutes per side, then bake at 400°F for 12-18 minutes, checking temperature early and often.
Cooking sirloin steak in the oven is a reliable technique that delivers excellent results. By following these steps—choosing a good steak, searing properly, using a thermometer, and resting—you’ll have a delicious, juicy steak ready for any night of the week. The precise answer to how long to cook sirloin steak in oven depends on your setup, but with this guide, you have all the information you need to get it right.
