Boneless prime rib steak cooked in the oven delivers a rich, beefy flavor with a perfectly seared crust. If you want to know how to cook boneless prime rib steak in the oven, this guide walks you through every step. You will get a tender, juicy steak with a deep brown outside and a pink, buttery center.
This cut is basically a ribeye without the bone. It has lots of marbling, so it stays moist even at higher heat. The oven does most of the work. You just need a hot pan, a good thermometer, and a little patience.
What Is A Boneless Prime Rib Steak
A boneless prime rib steak comes from the rib section of the cow. It is the same muscle as a ribeye, just cut without the bone. That means you get all the flavor and tenderness with less hassle.
These steaks are usually thick, often one to two inches. Thick cuts need a two-stage cooking method: sear first, then finish in the oven. This gives you a great crust without overcooking the middle.
- Also called a ribeye steak or Scotch fillet
- High fat content keeps it juicy
- Best cooked to medium rare or medium
- Works well with simple salt and pepper
How To Cook Boneless Prime Rib Steak In The Oven
This is the core method. Follow these steps and you will get a steakhouse-quality result at home. The total time is about 20 to 30 minutes, depending on thickness and doneness.
Step 1: Bring The Steak To Room Temperature
Take the steak out of the fridge 30 to 45 minutes before cooking. Cold meat cooks unevenly. A room-temperature steak sears faster and cooks more evenly inside.
Pat it dry with paper towels. Dry meat browns better. Any moisture on the surface will steam the steak instead of searing it.
Step 2: Season Generously
Use coarse salt and fresh cracked black pepper. Be generous. You can also add garlic powder, onion powder, or dried herbs like thyme and rosemary.
- Salt: about 1 teaspoon per side for a large steak
- Pepper: half a teaspoon per side
- Optional: a pinch of cayenne for heat
- Optional: a smashed garlic clove for the pan
Let the seasoned steak sit for 10 minutes while you preheat the oven and pan. This helps the salt stick and start to flavor the meat.
Step 3: Preheat Oven And Cast Iron Pan
Set your oven to 400°F (200°C). Place a cast iron skillet or heavy oven-safe pan on the stove over high heat. Let it get very hot, about 5 minutes.
A hot pan is key for a good crust. You can test it by dropping a tiny bit of butter or a water droplet. It should sizzle right away.
Step 4: Sear The Steak On The Stovetop
Add a high-smoke-point oil like avocado or canola to the hot pan. Place the steak in the pan. It should sizzle loudly.
Sear for 2 to 3 minutes per side without moving it. Use tongs to press down gently for even contact. You want a dark brown crust.
Add a tablespoon of butter and a smashed garlic clove in the last minute. Tilt the pan and spoon the butter over the steak. This adds flavor and helps the crust.
Step 5: Transfer To The Oven
Once both sides are seared, move the entire pan into the preheated oven. If your pan is not oven-safe, transfer the steak to a baking sheet or oven-safe dish.
Roast for 6 to 10 minutes for medium rare (130°F to 135°F internal). For medium, cook 8 to 12 minutes (140°F to 145°F). For medium well, 12 to 15 minutes (150°F to 155°F).
Always use a meat thermometer. Insert it into the thickest part, away from fat and bone. Do not guess by time alone because steak thickness varies.
Oven Time Chart For A 1.5-Inch Steak
- Rare (120°F to 125°F): 4 to 6 minutes
- Medium rare (130°F to 135°F): 6 to 8 minutes
- Medium (140°F to 145°F): 8 to 10 minutes
- Medium well (150°F to 155°F): 10 to 12 minutes
- Well done (160°F+): 12 to 15 minutes
Remember that the internal temperature will rise 5 to 10 degrees while resting. So pull the steak out 5 degrees before your target.
Step 6: Rest The Steak
Move the steak to a cutting board or plate. Cover it loosely with foil. Let it rest for 5 to 10 minutes.
Resting lets the juices redistribute. If you cut it right away, the juice runs out and the meat becomes dry. This step is not optional.
Step 7: Slice Against The Grain
Look at the direction of the muscle fibers. Cut across them, not along them. This shortens the fibers and makes each bite more tender.
Slice into half-inch thick pieces. Serve with the pan juices or a simple pan sauce.
Tips For The Best Boneless Prime Rib Steak
- Use a cast iron skillet for the best crust
- Do not overcrowd the pan; cook one steak at a time
- Dry the steak well before searing
- Let the pan get very hot before adding the meat
- Use a thermometer, not just time
- Rest the steak for at least 5 minutes
- Season simply so the beef flavor shines
Common Mistakes To Avoid
One common mistake is cooking cold steak. Another is not drying the surface. A wet steak will not sear.
Do not skip the rest. Do not cut the steak open to check doneness. Use a thermometer instead. Also, do not use olive oil for high-heat searing because it burns easily.
What To Serve With This Steak
Classic sides work best. Try mashed potatoes, roasted asparagus, or a simple green salad. A slice of crusty bread helps soak up the juices.
For drinks, a bold red wine like Cabernet Sauvignon pairs well. If you prefer beer, a brown ale or stout works too.
Can You Cook It From Frozen
Yes, but the results are not as good. If you must cook from frozen, add 50% more oven time and skip the stovetop sear. Sear it after it reaches room temperature, then finish in the oven. For best results, always thaw first.
