Juicy Air Fryer Sirloin Steak (Ready in 12 Minutes)
Air fryer sirloin steak is the fastest way to a juicy, seared steak on a busy night. It comes out tender, with a crust you’d swear came off a grill, all from a gadget that handles the heat while you make a quick side.
With a simple garlic herb butter melting over the top, this feels like a restaurant plate but takes about 15 minutes from start to finish. No smoke alarms, no splattered oil.
Why This Air Fryer Steak Works
Sirloin is a lean, flavorful cut that stays tender when you don’t overcook it. The air fryer’s high heat sears the outside while the inside stays pink and juicy, and there’s hardly any moisture to steam off.
I reach for this method when I want a steak that tastes like a splurge but cooks in under 12 minutes. The herb butter is optional, but it adds a savory richness that soaks right into every slice.
Ingredients
- 2 boneless sirloin steaks, about 8 oz (225 g) each and 1 inch thick: thickness matters for even cooking.
- 1 tbsp olive oil: helps the seasonings stick and the crust form.
- 1 tsp kosher salt: or ¾ tsp table salt.
- ½ tsp black pepper
- 1 tsp garlic powder: adds savory depth, or use onion powder.
- 2 tbsp unsalted butter, softened
- 1 garlic clove, minced
- 1 tbsp finely chopped fresh parsley: or 1 tsp dried parsley.
Variations / Substitutions
- Swap the steak cut: try strip steak or ribeye. Both work, but adjust the time for thickness.
- Switch the seasoning: use a store-bought steak seasoning blend, or add smoked paprika and a pinch of cayenne.
- Skip the herb butter: for a simpler steak, or use a pat of plain butter after resting.
- For a dairy-free option, finish with a drizzle of olive oil and a squeeze of lemon instead of butter.

How to Make Air Fryer Sirloin Steak
Step 1: Season the Steaks
Pat the 2 sirloin steaks dry with paper towels, then rub all sides with the 1 tbsp olive oil. Mix the 1 tsp kosher salt, ½ tsp black pepper, and 1 tsp garlic powder in a small bowl, then press the mixture onto both sides of each steak.
The coating should be even and you’ll see the tiny granules of pepper. Let the steaks sit at room temperature for about 20 minutes while the air fryer preheats. That pause helps them cook more evenly.
Step 2: Air Fry the Steaks
Preheat the air fryer to 400°F (200°C). Place the steaks in the basket in a single layer, leaving a little space around each. Cook for 8 to 12 minutes, flipping halfway through, until an instant-read thermometer reads 125°F (52°C) for medium-rare.
The outside will turn deep brown, and small beads of juice will appear on the surface. If you like your steak more done, add an extra 1 to 2 minutes, but keep an eye on the temperature. Sirloin goes from pink to gray quickly.
Step 3: Whip the Herb Butter
While the steaks cook, mash the 2 tbsp softened butter in a small bowl with the minced garlic clove and 1 tbsp chopped parsley until combined.
You can also add a pinch of salt and a little lemon zest if you like a bit of brightness. The mixture will be soft and fragrant, ready to melt the moment it hits the hot steak.
Step 4: Rest, Slice, and Serve
Transfer the steaks to a cutting board and let them rest for 5 minutes. Slice against the grain into thick strips, then spoon the herb butter over the top. The butter will melt into a glossy sauce that mixes with the resting juices on the board.
Tips for a Juicy Air Fryer Steak
- If your steaks are thicker than 1 inch, increase the cook time by 2 to 3 minutes and start checking the temperature a minute earlier.
- Don’t crowd the basket. Leave an inch between steaks so the hot air can circulate. If cooking more than two, work in batches.
- The herb butter can be made ahead and stored in the fridge for up to a week. Let it come to room temperature before spooning it onto the hot steak.
Cook times by thickness and doneness:
| Thickness | Medium-Rare (125°F) | Medium (135°F) |
|---|---|---|
| 1 inch | 8 to 10 mins, flip halfway | 10 to 12 mins |
| 1.5 inches | 10 to 12 mins | 12 to 14 mins |
Keeping Leftovers Fresh
- Refrigerate: Place cooled steak in an airtight container for up to 4 days. Slice before storing if you plan to use it cold in salads.
- Reheat: Air fryer at 350°F for 2 to 3 minutes just until warm, or slice thinly and warm in a skillet with a splash of broth or butter.
- Serve Cold: Leftover steak is excellent on a salad or in a wrap. It stays tender straight from the fridge.
What to Serve with Sirloin Steak
A warm, starchy side like garlic mashed potatoes or air fryer fries soaks up the butter and juices. For something green, an arugula salad with lemon vinaigrette cuts through the richness in the best way.
Frequently Asked Questions
Can I cook frozen sirloin steaks in the air fryer?
Yes, but you’ll get better results if you thaw them first. Frozen steaks tend to cook unevenly and the exterior can overbrown before the center warms.
How do I get a really good crust in an air fryer?
Make sure the steak is dry, coated in oil, and the air fryer is fully preheated. Opening the basket too often lets heat escape, so flip quickly.
What if I don’t have an instant-read thermometer?
You can use the finger test, but a thermometer is the most reliable way to hit your doneness. For medium-rare, the steak should feel soft and springy when pressed.
Is sirloin steak always tough?
It’s a lean cut, so it can be chewy if overcooked. Aim for medium-rare or medium, slice against the grain, and it will be tender.
