T-bone steak is a bone-in beef steak with a strip steak on one side of the bone and a smaller tenderloin on the other. On a hot gas grill, a 1- to 1¼-inch steak typically takes about 10–14 minutes over direct heat; a thermometer, rather than the clock, tells you when it is done.
Ingredients
- 2 T-bone steaks, 1 to 1¼ inches thick (about 12–16 oz / 340–454 g each)
- 1 tablespoon neutral high-heat oil, such as canola or avocado oil (15 ml)
- 1 teaspoon fine sea salt (6 g)
- ½ teaspoon freshly ground black pepper (about 1 g)
- 2 tablespoons unsalted butter, softened (28 g), optional for serving
- 1 small garlic clove, finely grated or minced (about 3 g), optional for the butter
- 1 tablespoon chopped fresh parsley (about 4 g), optional for the butter
Instructions
- Prepare the steaks. Take the steaks from the refrigerator while you set up, but don’t leave raw meat at room temperature for an extended period. Pat both sides dry with paper towels; a dry surface browns more readily than a damp one. Rub with the oil, then season evenly with the salt and pepper, including the edges. If using the optional butter, stir the softened butter with the garlic and parsley in a small bowl and set it aside. This takes about 10 minutes, including mixing the butter.
- Preheat the gas grill. Turn the burners to high, close the lid, and heat the grill for about 15 minutes. Aim for a hot cooking grate and a grill temperature around 450–500°F (232–260°C). Brush the grate clean with a grill brush, then lightly oil it using a folded paper towel held with long tongs. If your grill has several burners, leave one burner on low or off to create a cooler zone for finishing the steaks if needed.
- Start over direct heat. Place the steaks on the hot grate over the lit burners and close the lid. Grill for about 4–5 minutes on the first side without moving them, which helps develop browned grill marks. Keep the lid down to maintain heat, but stay nearby; flare-ups can happen when fat drips onto the burners. If flames rise around the meat, move the steaks briefly to the cooler zone rather than letting them scorch.
- Turn and continue grilling. Flip the steaks with tongs and grill the second side for about 4 minutes. For steaks around 1¼ inches thick, the total direct-grilling time is often 10–14 minutes, with a turn every 4–5 minutes. These times are an estimate: grill output, steak shape, starting temperature, and thickness all affect cooking speed. Avoid pressing the steaks with a spatula, which squeezes out juices without making them cook better.
- Check the temperature carefully. Insert an instant-read food thermometer sideways into the thickest part of the strip section, keeping the probe away from the bone. Check the tenderloin section separately if it is large enough to measure; it can cook faster than the strip. The USDA FSIS safe minimum for whole cuts of beef is 145°F (63°C), followed by a rest of at least 3 minutes. If a steak has not reached that temperature, move it to the cooler grill zone, close the lid, and check again every minute or two. A clock or the color of the outside cannot confirm a safe internal temperature.
- Rest before serving. Transfer the steaks to a clean plate or cutting board and rest for 5 minutes; this gives the juices time to settle and meets the required minimum rest. The recipe’s estimated 12 minutes of cooking is a midpoint, not a substitute for checking temperature. If using garlic-parsley butter, place a small amount on each hot steak during the rest so it melts over the surface.
- Slice and serve. For easier serving, cut the meat away from the T-shaped bone, then slice the meat across the grain into strips. Keep the bone on the platter if you like, and spoon any melted herb butter over the slices. Serve promptly while the steak is warm.
Tips
- Thickness changes the timing. The 10–14-minute estimate is for steaks about 1 to 1¼ inches thick. A thinner steak may reach temperature sooner; a steak closer to 1½ inches may need more time and benefit from a cooler-zone finish. Measure thickness at the thickest point, and let the thermometer determine doneness.
- Use two heat zones to prevent burning. T-bones have a large fat edge that can drip and flare, and the tenderloin side is leaner and smaller than the strip side. A hot zone gives you browning; a cooler zone gives you somewhere to move a steak if the outside darkens before the center reaches 145°F (63°C).
- Keep seasoning simple, or adjust it to taste. Fine sea salt and black pepper let the beef’s flavor stand out. You can substitute kosher salt, but crystal sizes vary, so use a modest amount and season to taste. Canola or avocado oil can be swapped for another neutral oil suitable for high heat; extra-virgin olive oil has a more pronounced flavor and may smoke sooner.
- Don’t rely on grill marks or a timer alone. A deeply browned outside does not tell you the temperature at the center. Use an instant-read thermometer, avoid touching the probe to the bone, and clean tongs or a plate before using them for cooked steak.
Serving Suggestions
Serve grilled T-bone with a crisp green salad, grilled asparagus, or sliced tomatoes to balance the richness of the steak. For a more filling meal, pair it with baked potatoes, grilled corn, roasted potatoes prepared ahead, or crusty bread to catch the juices. A simple side of sautéed mushrooms or onions also works well, but cook it separately so the steak can rest undisturbed. For two people, the bone-in steaks make a generous main course; if the steaks are especially large, slice the meat and share it family-style with several sides.
Variations
For a peppery crust, add extra coarsely cracked black pepper just before grilling, taking care not to let loose pepper burn over a flare-up. For a smoky, savory seasoning, use a small pinch of smoked paprika along with the salt and pepper; it adds a smoky note but does not replace the flavor of grilling. You can also swap the garlic-parsley butter for plain salted butter, or leave it off and finish with a squeeze of lemon for a brighter taste.
To make a quick herb finish without butter, mix 1 tablespoon (15 ml) olive oil with 1 teaspoon (5 ml) lemon juice and a little chopped parsley, then spoon it over the rested steak. The result is lighter and sharper than the buttery version. If you prefer a different cut, a bone-in strip steak can be grilled using the same temperature checks, though its shape and thickness may change the timing. Rib-eye is fattier and can cause more flare-ups, so keep the cooler zone ready.
Storage and Reheating
Refrigerate leftover steak within 2 hours of cooking, storing it in a shallow airtight container. It keeps for 3–4 days in the refrigerator. If you have a large leftover steak, remove the meat from the bone before storing so it cools and reheats more evenly. Keep any herb butter separate if it has not already melted onto the meat.
For the best texture, reheat slices gently in a covered skillet with a teaspoon or two of water or broth, just until hot. You can also microwave small portions in short bursts, turning the pieces between bursts to heat them evenly. USDA guidance is to reheat leftovers to 165°F (74°C); steak reheated that thoroughly can become less tender, so slice it thinly and add a little liquid. Leftover steak is also good cold, sliced over a salad, as long as it has been stored safely. Freeze portions in airtight wrapping for up to 2–3 months for best quality, then thaw in the refrigerator before reheating.
Frequently Asked Questions
How long should I cook a 1-inch T-bone steak on a gas grill?
Plan on roughly 10–12 minutes over direct heat, turning once or twice, but treat that as a starting estimate. A particularly hot grill or a thinner steak can cook faster. Check the thickest meat with an instant-read thermometer and follow the USDA safe minimum of 145°F (63°C) with a 3-minute rest.
Should I grill T-bone steak with the lid open or closed?
Keep the lid closed for most of the cook. A closed lid holds heat around the steak and helps the center cook without requiring a long time over the flame. Open it briefly to turn the steaks and check for flare-ups. On a very thin steak, you may need a shorter cook and more frequent checks.
Do I need to flip a T-bone steak more than once?
No. One flip is enough for this method, and turning once after the first 4–5 minutes makes the timing easy to follow. Turning more often is also fine if you are managing hot spots or flare-ups; it does not make the steak unsafe. Use tongs rather than a fork so you do not pierce the meat.
Can I grill a T-bone steak straight from frozen?
It is better to thaw it in the refrigerator first. A frozen steak can brown on the outside before the center cooks, and the two sides of a T-bone may heat unevenly. Thaw it in a covered container in the refrigerator, pat it dry, and then use the timing and thermometer guidance above. Do not thaw raw steak on the counter.
What if I like my steak medium-rare?
Many cooks prefer steak cooked below 145°F (63°C), but that is below the USDA FSIS safe minimum for whole cuts of beef. The method here uses 145°F (63°C) followed by at least a 3-minute rest as the safety target. A thermometer gives you a reliable reading; appearance and firmness are not dependable ways to judge internal temperature.
