Thick steaks need careful timing in an air fryer, often 12 to 18 minutes total, depending on your preferred doneness level. So how long do you cook a thick steak in an air fryer if you want it juicy inside and browned on the outside? The answer comes down to thickness, temperature, and a quick rest at the end.
This guide breaks the process into simple steps. You will get exact times, temps, and tips for a steak that tastes like it came off a grill.
Why Thick Steaks Need Different Timing
A thick steak, usually 1.5 to 2 inches, holds more cold meat in the center. That means it needs more time to reach a safe internal temperature without drying out the edges.
Thin steaks cook fast and can overcook in minutes. Thick cuts give you a bigger window, but they still need attention. The air fryer moves hot air around the meat, so both sides brown without flipping in oil.
- 1-inch steak: 10 to 14 minutes
- 1.5-inch steak: 12 to 16 minutes
- 2-inch steak: 15 to 20 minutes
These times are for a 400°F air fryer. Your model may run a little hotter or cooler, so check early the first time.
How Long Do You Cook A Thick Steak In An Air Fryer
Here is the short answer. For a 1.5-inch thick steak at 400°F, cook 6 minutes per side for medium-rare. That is about 12 minutes total. Add 2 to 3 minutes per side for medium, and 4 minutes per side for well done.
Always use a meat thermometer. Pull the steak 5°F below your target because it keeps cooking while it rests.
Time And Temperature Chart By Doneness
- Rare: 120°F to 125°F, 10 to 12 minutes total
- Medium-rare: 130°F to 135°F, 12 to 14 minutes total
- Medium: 140°F to 145°F, 14 to 16 minutes total
- Medium-well: 150°F to 155°F, 16 to 18 minutes total
- Well done: 160°F and up, 18 to 20 minutes total
These numbers assume you preheat the air fryer. A cold basket adds 2 to 3 minutes to the cook.
Step-By-Step Cooking Method
Follow these steps for a thick steak that is browned outside and tender inside.
- Take the steak out of the fridge 20 to 30 minutes before cooking. Room temp meat cooks more even.
- Pat the steak dry with paper towels. Wet meat steams instead of sears.
- Rub both sides with oil, salt, and pepper. Use about 1 teaspoon of oil per side.
- Preheat the air fryer at 400°F for 5 minutes. Do not skip this.
- Place the steak in the basket. Leave space around it so air can flow.
- Cook 6 minutes, then flip with tongs. Do not use a fork, it lets juice out.
- Cook another 6 minutes for medium-rare. Check the temp with a thermometer.
- Rest the steak on a board for 5 to 10 minutes before slicing.
Resting is not optional. It lets the juices settle so they stay in the meat, not on the plate.
Tips For A Better Sear
Air fryers do not get as hot as a cast iron pan, but you can still get a good crust.
- Dry the surface well before seasoning
- Use a light coat of high smoke point oil like avocado or canola
- Do not crowd the basket, cook one steak at a time if needed
- Flip only once, halfway through
- For extra browning, broil the steak 1 to 2 minutes at the end if your model has that setting
Common Mistakes To Avoid
Most air fryer steak problems come from a few easy-to-fix errors.
Overcrowding The Basket
Two thick steaks in a small basket will steam, not sear. Cook them in batches or use a larger model.
Skipping The Preheat
A cold air fryer means uneven cooking. The outside browns before the inside warms up. Always preheat.
Not Using A Thermometer
Time is a guide, but temp is the truth. A $15 thermometer saves you from a tough, gray steak. Stick it into the side of the steak, not the top.
Cutting Too Soon
If you slice right away, juice runs out and the meat turns dry. Wait at least 5 minutes.
How Thickness Changes The Cook Time
The keyword here is thickness. A 1-inch steak and a 2-inch steak are very different jobs.
1-Inch Steak
Cook at 400°F for 5 minutes per side. Total time is 10 minutes for medium-rare. These are easy to overcook, so watch close.
1.5-Inch Steak
This is the sweet spot. Cook 6 minutes per side, 12 minutes total for medium-rare. The outside gets a nice crust and the center stays pink.
2-Inch Steak
Cook 7 to 8 minutes per side. Total time is 15 to 16 minutes for medium-rare. If the outside browns too fast, drop the temp to 380°F and add a few minutes.
What About Frozen Thick Steaks
You can cook a frozen steak in an air fryer, but add time. A frozen 1.5-inch steak needs about 20 to 25 minutes at 400°F. Flip halfway. The outside may cook before the inside thaws, so use a thermometer and check at 18 minutes.
For best results, thaw overnight in the fridge. The texture and taste are much better.
Resting And Serving
After the steak rests, slice against the grain. This cuts the muscle fibers short and makes each bite tender.
Serve with simple sides. Roasted potatoes, green beans, or a small salad all work well. A pat of butter on top while it rests adds flavor without much work.
Final Timing Recap
For a thick steak in an air fryer at 400°F, plan on 12 to 18 minutes total. Use 6 minutes per side for medium-rare on a 1.5-inch cut. Add time for thicker steaks or a more done center. Check the temp, rest the meat, and you will get a steak that is juicy and browned every time.
Once you cook a thick steak this way a couple times, you will know your air fryer’s quirks. Then you can adjust by a minute or two and get it right on the first try.
