Ingredient Notes
- Tempeh - Any brand of tempeh you like is fine. Just make sure to choose a variety made with 100% soybeans if you need gluten-free since some varieties have grains added. Honestly, I think the pure soybean tempeh tastes best!
- Tamari - If you don't need gluten-free, soy sauce or shoyu may be used instead. Or go with liquid aminos.
- Maple syrup - A touch of sweetness is important for the overall flavor of the marinade. You want pure maple syrup, not imitation.
- Sriracha - Gives the marinade a thicker, glaze-like consistency and adds delicious tang. We're not adding enough sriracha to make the tempeh spicy, but you can always add more later if you want it hot!
- Liquid smoke - I use Colgin's brand in hickory or mesquite. These can be found in almost any grocery store.
- Oil - Choose a neutral cooking oil like avocado or grapeseed. If you avoid oil simply omit it. The tempeh will lose some of the richness and look a bit dry on the outside, but will still taste great.
- Vinegar - A little bit of apple cider vinegar rounds out the sweet-and-tangy Asian BBQ vibes

How to Air Fry Tempeh
- First, whisk together the marinade in a large bowl or other dish.
- Cut the block of tempeh into either 24 or 36 pieces, about ½- to ¾ inch thick. I prefer the smaller pieces because that means there's more surface area for the marinade. Or if you'd rather thinly slice the tempeh, that works, too. And cook time is even quicker!
- Toss the tempeh in the marinade and set aside for 30 minutes. I like to pass through the kitchen once or twice during that time to spoon the extra marinade from the bottom of the bowl over top just to make sure all the pieces are well coated. If you're working with thinly sliced tempeh, just be gentle as you stir so they don't fall apart.
- Now, the trick! Pour approximately 1 cup of water in the bottom of the air fryer basket, making sure it's not up to the level of the grate. Preheat the air fryer to 350°F. Once preheated, arrange the tempeh in a singler layer. Cook for about 10 minutes (or 7-8 minutes for strips), checking on it at the halfway point and during the last couple of minutes. See the Tips section below.
Do I have to add water to the bottom of the air fryer?
Have you ever heard that you should steam tempeh because it reduces tempeh's natural bitterness? Well, adding water to the air fryer basket has the same effect here. But as a bonus, it's not an extra step!
To answer the question, you don't have to add water, but during recipe testing we found that it really does make it more delicious.
With this simple trick it's like we're steaming and air frying the tempeh at the same time. The steam also keeps the marinade nice and sticky and makes the tempeh moist, yet firm and meaty.
Even with the steam, the edges still brown and caramelize.
Oven Option
If you don't have an air fryer that's no problem! I also tested this recipe in the oven. Here's how to do it:
- Marinate the tempeh as described, and preheat the oven to 425°F (215°C). Line a baking sheet with parchment paper or a silicone mat.
- Bake the tempeh for 18 to 23 minutes (about 15 min. for strips), or until it's as chewy and caramelized as you like.

Serving Suggestions
Air Fryer Tempeh is a delicious addition to so many meals. Add it to wraps, salads, noodles, and grain bowls. Slice it for sandwiches or make a vegan banh mi.
It's also a flavorful vegan appetizer to serve at a dinner party. Start the air fryer when your guests arrive, then serve these tasty morsels alongside your favorite vegan cheeses, dairy-free dips, and crackers.
For dessert, give the air fryer basket a quick rinse and prepare these juicy air fryer peaches!
Variations
- Gluten-free - I suppose this isn't really a variation because the recipe is gluten-free as written, but just to point out the two main things to watch out for: use gluten-free tamari, and select a tempeh made from soybeans only (some varieties include grains).
- Oil-Free - If you strictly avoid oil in your diet you'll be happy to know you can simply omit it. The result isn't quite as flavorful and the tempeh will look a bit dry, but thanks to the water in the bottom of the air fryer, it doesn't actually dry out. The end result is still delicious!
- Spicy - we love this tempeh with a few dashes of cayenne pepper or crushed red pepper flakes added to the marinade. For extra spicy, serve the air fryer tempeh with additional sriracha, gochujang, or other hot sauce.
- Korean BBQ - for a slight twist, toss the tempeh with this Korean BBQ sauce instead of the included sauce recipe.

Equipment & Batch Size
I use this 6-Quart Instant Vortex Air Fryer, but any comparable air fryer works for this recipe.
If you plan to cook two packages of tempeh (doubling the recipe), a 6 quart machine should be large enough. Otherwise you'll want to work in batches.
You'll also need a large bowl or container for marinating the tempeh.
How to Store and Reheat
Store leftover tempeh in the refrigerator for up to 5 days. The texture is best when it's fresh from the air fryer. Reheat tempeh in the air fryer or in a skillet on the stovetop.
I haven't tried freezing this tempeh yet because we always gobble it up! But in general tempeh is freezer friendly.
Helpful Tips
Type of Air Fryer: If you're using a toaster-oven style air fryer instead of a basket or drawer-style, add the water to a shallow, oven-safe dish and place on the bottom rack.
Cook time: Air fryers vary. So the first time you try any air fryer recipe it's a good idea to keep a close eye on things. Check on the tempeh at the halfway mark and during the final 2-3 minutes.
You may need to adjust the temperature and/or cook time for your particular air fryer. When the tempeh is sizzling hot and has yummy browned bits on the edges you'll know it's done.
It also helps to sneak a test bite. 🙂

Recipe
Air Fryer Tempeh Recipe
Equipment
Ingredients
- 8 ounces tempeh (1 package)
- 1 ½ tablespoons tamari (for GF) or soy sauce
- 1 ½ tablespoon maple syrup
- 2 teaspoons cooking oil such as avocado or grapeseed - For oil-free, omit or sub 1 tablespoon tahini.
- 2 teaspoons sriracha
- 1 teaspoon apple cider vinegar
- ½ teaspoon liquid smoke
- ½ teaspoon garlic powder
- scant ½ teaspoon fine sea salt
- ¼ teaspoon smoked paprika
- ¼ teaspoon black pepper
Instructions
- To make the marinade, in a large bowl or dish, whisk together all ingredients except the tempeh. Cut the tempeh into either 24 or 36 squares. I prefer smaller pieces because it creates more surface area for the flavorful marinade. The cubes will be approx. ½- to ¾-inch. Alternatively, slice the block of tempeh into thin strips.
- Toss the tempeh in the marinade making sure all pieces are well coated. Set a timer for 30 minutes. Once or twice during that time spoon the marinade from the bottom of the bowl over the tempeh.
- Once the tempeh is marinated, add ¾ to 1 cup water to the bottom of the air fryer basket then insert the rack. Preheat the air fryer to 350 degrees F. Once preheated, arrange the tempeh in a single layer (refer to photos in post above if needed). It should be sitting above the water line.
- Cook for about 10 minutes (or 8 minutes for strips), checking on it at the halfway point and during the last 2-3 minutes to make sure it isn't burning. The tempeh is done when piping hot and caramelized around the edges. Serve hot.

I really love your recipes. They are creative and delicious. I haven't made the tempeh yet because I have a Cuisinart toaster oven with air fryer, grilling and
convention abilities. How would you cook the tempeh?
Thank you,
Jo
Lori Rasmussen says
Thanks so much, Jo!
If there's room in the toaster oven, maybe you could add a shallow tray of water on the bottom shelf, and the tempeh above, then use the air fryer setting. Or if the water doesn't work, you could lightly steam the tempeh first before marinating or skip the steaming altogether. Hope that helps!
