Wagyu steak is a rich, tender beef dish made with wagyu, a term for Japanese cattle and beef that is also produced in other countries. This cast-iron recipe uses a brief dry brine, a hot sear, and a short oven finish, then serves the steak simply so its buttery flavor stays at the center of the plate.
The method is intended for two thick-cut steaks, such as American wagyu ribeye or strip steak, rather than very thinly sliced Japanese A5 wagyu. Wagyu beef varies in marbling and richness, so modest seasoning and a small amount of cooking fat are enough.
Ingredients
- 2 wagyu ribeye or strip steaks, each 1¼ inches (3 cm) thick and about 10–12 ounces (285–340 g)
- 1 teaspoon (5 g) kosher salt
- ½ teaspoon (1 g) freshly ground black pepper
- 1 teaspoon (5 ml) neutral high-heat oil, such as avocado or refined canola oil
- 1 tablespoon (14 g) unsalted butter
- 1 garlic clove (about 3 g), lightly crushed
- 2 fresh thyme sprigs (about 2 g), optional
- Flaky salt, up to ¼ teaspoon (about 1 g), for serving, optional
Instructions
- Dry-brine the steaks. Pat the steaks dry with paper towels and place them on a plate or small rack. Sprinkle the salt evenly over both sides. Refrigerate uncovered for 30 minutes. This gives the salt time to season the meat and helps the surface dry for better browning. Meanwhile, measure the remaining ingredients and preheat the oven to 400°F (205°C) during the final 10 minutes of the chill. If you cannot fit a rack in the refrigerator, a plate works; turn the steaks once halfway through the chill.
- Prepare the pan and steaks. Take the steaks from the refrigerator, blot away any moisture on the surface, and season both sides with black pepper. Set a heavy, oven-safe skillet—cast iron is ideal—over medium-high heat for about 3 minutes. The pan should be thoroughly hot but not smoking heavily. Wagyu renders more fat than lean beef, so the measured teaspoon of oil is just enough to help the surface make contact with the pan.
- Sear the first side. Add the oil and swirl it across the skillet. Lay in the steaks, leaving space between them, and sear without moving for about 2 minutes. Lift an edge with tongs to check the crust; if it is still pale, give it another 30 seconds. The steak should release more easily once a brown crust has formed. If the pan is too small for both steaks, sear them one at a time rather than crowding them.
- Sear the second side and edges. Turn the steaks with tongs and sear the second side for about 2 minutes. Briefly hold each steak on its fat edge for 20–30 seconds if it has a thick outside strip. Add the butter, crushed garlic, and optional thyme. Tilt the pan carefully and spoon the foaming butter over the steaks for about 30 seconds. Keep the butter moving; if it turns dark or smells acrid, stop basting and move the pan off the heat.
- Finish in the oven and check the temperature. Transfer the skillet to the preheated oven. Begin checking after 3 minutes, inserting an instant-read thermometer horizontally into the center of each steak without touching the pan. Cooking time depends on the steak’s exact thickness and the starting temperature. For food safety, USDA FSIS recommends whole cuts of beef reach a safe minimum internal temperature of 145°F (63°C), followed by a 3-minute rest. Remove each steak when it reaches 145°F (63°C); if the steaks differ, take them out individually as they reach that temperature.
- Rest, slice, and serve. Transfer the steaks to a warm plate or board and rest for 3 minutes. This rest is part of the required food-safety guidance and gives the juices time to settle. Slice across the grain into thick strips, spoon over any clean butter and pan juices, and finish with a small pinch of flaky salt if desired. Taste before adding more salt, since the dry brine has already seasoned the meat.
Tips
- Choose the right cut and thickness. A 1¼-inch (3 cm) ribeye or strip is thick enough to develop a crust before the center finishes in the oven. If your steaks are thinner, check them earlier and expect the oven stage to be shorter. Very thin slices of A5 wagyu are better suited to a quick tabletop-style sear, but this recipe’s temperature and timing are for thick steaks.
- Use less fat than you would for lean beef. Wagyu marbling renders as the steak cooks. A teaspoon of neutral oil is enough to start the sear; adding a generous pour can make the pan greasy and encourage splattering. If you do not have avocado or refined canola oil, use another neutral oil labeled for high-heat cooking. Extra-virgin olive oil can smoke sooner and may add a noticeable flavor.
- Let the thermometer decide. Steak color and firmness are unreliable ways to judge the center, especially with highly marbled beef. Check the thickest part of each steak, and clean the thermometer probe after use. Do not rely on the stated oven time alone; a slightly thicker cut or a cooler pan can change the finish time.
- Keep the pan manageable. If the butter starts smoking, lower the heat or briefly lift the skillet off the burner. A heavy pan holds heat, and burned butter can turn bitter. The garlic and thyme are optional aromatics, not a sauce that needs to cook down; remove them if they brown quickly.
Serving Suggestions
Serve the steak as the main course while it is hot, with a modest side that can balance its richness. Steamed rice, roasted potatoes, or a small bowl of plain mashed potatoes all work well. For a lighter plate, add crisp green beans, simply dressed leafy greens, or quickly sautéed mushrooms. A squeeze of lemon over vegetables—not necessarily over the steak—can add a bright contrast.
For a Japanese-inspired meal, serve thin slices with steamed rice, a little grated daikon, and a small dish of soy sauce or ponzu. Ponzu is a citrus-seasoned soy sauce; if it is not available, mix soy sauce with a little lemon juice, knowing that the substitute will be sharper and less rounded. Keep dipping sauces on the side so diners can choose how much to use and the beef’s flavor is not covered up.
For two people, slice the steak after resting and arrange it on a shared warm plate. Put the pan juices in a small dish for spooning, and serve the sides separately. Since wagyu can feel especially rich in a large portion, the recipe’s two steaks are intended to serve two people as a substantial main; smaller portions can be paired with extra rice or vegetables.
Variations
Garlic-thyme finish: The recipe already offers butter, crushed garlic, and thyme as optional aromatics. Use rosemary instead of thyme if that is what you have; its flavor is more resinous, so one small sprig is plenty. You can also leave out the butter and herbs and finish with only the steak’s own pan juices for a cleaner, less rich plate.
Simple soy-citrus dip: Stir together 1 tablespoon (15 ml) soy sauce and 1 teaspoon (5 ml) lemon juice or yuzu juice. Serve it in a small dish beside the steak rather than pouring it into the hot pan, where it could scorch or make the crust soggy. Yuzu has a distinct floral citrus flavor; lemon is a practical substitute but tastes more direct and tart.
Grill instead of using the oven: Heat a clean grill to medium-high and sear the steaks over direct heat, turning as needed to brown both sides and the edges. Move them to a cooler part of the grill if the outside is darkening before the center reaches the USDA FSIS safe minimum temperature of 145°F (63°C). Check each steak with a thermometer and rest for 3 minutes. Grills vary, so use internal temperature rather than a fixed finishing time.
Use a different wagyu cut: Wagyu sirloin can replace ribeye or strip if it is cut to the same thickness, though it may be less tender and less marbled. A very highly marbled Japanese A5 steak is richer than many American wagyu steaks; serve a smaller amount with rice and vegetables. Do not assume that its marbling changes the recommended safe temperature for a whole cut of beef.
Storage and Reheating
Refrigerate leftover steak within 2 hours of cooking, in a shallow airtight container. Cooked steak keeps for 3–4 days in the refrigerator. For the best texture, store sliced steak with any pan juices rather than leaving it exposed to air. Freeze tightly wrapped portions for about 2–3 months for best quality, then thaw them in the refrigerator; the texture may be a little less tender after freezing.
To reheat safely, warm the leftovers in a covered skillet over low heat with a spoonful of water or pan juices, turning once, until the center reaches 165°F (74°C). Check with a food thermometer, since reheating time depends on the thickness and amount. This temperature can make steak more done than when freshly cooked, so use gentle heat and avoid reheating the same portion more than once. Cold, thin slices can also be added to a salad or rice bowl without reheating, provided they have been stored safely.
Frequently Asked Questions
What is the difference between wagyu and regular steak?
Wagyu refers to beef from particular Japanese cattle breeds and their descendants. The term is also used for beef raised outside Japan, and its marbling can vary considerably by animal, cut, and producer. A more marbled steak generally renders more fat as it cooks, which is why this recipe uses little added oil and restrained seasoning.
Can I cook wagyu steak entirely in a skillet?
Yes, if the steak is thin enough to reach the recommended temperature while searing without burning the outside. For a 1¼-inch steak, the oven finish makes it easier to control the center after browning. If you keep it on the stovetop, lower the heat after searing and turn it regularly, checking the center with a thermometer rather than guessing from the clock.
Do I need to bring the steak to room temperature first?
No. This recipe seasons the steak in the refrigerator and cooks it directly from chilled after blotting the surface dry. Leaving raw meat out for a long period does not guarantee more even cooking, and perishable food should not sit at room temperature for more than 2 hours total. A thermometer is the reliable way to check the center.
Can I use salted butter or table salt?
Unsalted butter makes it easier to control the seasoning, but salted butter is fine if you use a little less kosher salt. Table salt is denser by volume than many kosher salts, so use about ½ teaspoon (3 g) table salt in place of the teaspoon of kosher salt, then adjust only after tasting. Salt crystal sizes vary, so the weight is the more useful guide.
Why did my steak stick to the cast-iron pan?
It may have been moved before the crust formed, or the skillet may not have been hot enough when the steak went in. Let the pan preheat, pat the steak surface dry, and give the first side about 2 minutes before testing whether it releases. If the steak still clings, wait another 30 seconds rather than pulling hard and tearing the browned surface.
Is medium-rare wagyu safe to serve?
USDA FSIS recommends that whole cuts of beef reach 145°F (63°C), followed by a 3-minute rest. That is the safe-minimum guidance used in this recipe. If you choose a lower temperature for preference, understand that it is below that recommendation; use a thermometer and consider the needs of anyone eating the meal.
