Crispy Marinated Air Fryer Tempeh

Tempeh is one of the best plant-based proteins and is versatile enough to be used in many different meals. This recipe features crispy, herb-marinated tempeh that you can make using an air fryer, which I highly recommend. 

PS, it’s pronounced (tem-pay), not like Tempe the town.

Fresh tempeh is usually pale beige with a firm, compact texture. You’ll see a consistent white coating holding the soybeans together. Some small gray or brown spots on the soybeans are normal, but large dark patches or fuzz that looks off-white/green/black can indicate it’s gone bad.

It should smell slightly nutty, earthy, and mildly fermented think subtle yogurt or mushroom notes. If it smells strongly sour, ammonia-like, or rotten, it’s past its prime. Fresh tempeh feels firm but slightly springy when you press it, not gooey or mushy.

Nutrition Notes

As a registered dietitian I have to point out some of tempeh's nutrient highlights. Plant proteins usually come with more than just protein making them a desirable choice when varying protein sources.  

Protein 

Tempeh has a good amount of protein in a small serving. You get about 16 grams in just three ounces, which helps you stay full and supports muscle repair. Think about meals where protein usually falls short and plug tempeh into those spots.

Probiotics 

Fermentation adds helpful probiotics. These microbes support healthy digestion and may improve how you absorb nutrients. You might notice less bloating when you include fermented foods regularly.

Tofu Compared to Tempeh

If you’re deciding between plant-based proteins, it helps to know how tempeh and tofu compare. Both are soy-based, but they differ in protein, texture, flavor, and how they behave in cooking. Understanding these differences can help you pick the right one for you.

Protein: Tempeh has more protein per serving about 16 grams per 3 ounces, vs 8 grams per 3 ounces of firm tofu. Tempeh is an excellent option if you’re aiming to hit higher daily protein goals. However, it is important to vary proteins throughout the day. 

Texture: Tempeh is firm and chewy, which holds up well in air frying, grilling, or stir-fries. Tofu is softer and more delicate, especially silken or soft varieties, making it better for soups, scrambles, or creamy sauces depending on which type of tofu you use.

Flavor: Tempeh has a nutty, earthy flavor that stands out and complements marinades well. Tofu is very mild, so it absorbs flavors quickly but needs stronger seasoning or will lack flavor. Read What Does Tofu Taste Like for a more in depth review of what vegans have to say. 

Cooking versatility: Tempeh holds its shape well for grilling, air frying, or skewers. Tofu can crumble or fall apart if not pressed and handled carefully.

Ingredients

Here's what you need to whip up this easy air fryer tempeh.

Tempeh: The star of the show! I often hear that people think tempeh is bitter, to reduce the flavor, boiling tempeh for a few minutes softens its flavor and reduces the mild bitterness. The brand I like the most is LightLife. I also like their “Fakin Bacon” which is pre-seasoned. 

Low-sodium soy sauce: Adds deep flavor with less salt. For even less sodium, you can use coconut aminos which is also a gluten free option.

Maple syrup: Brings a touch of sweetness. A small amount helps balance the salty and smoky flavors. You also get trace minerals like manganese.

Spices: Seasoning plant based proteins is a must, just like how animal based proteins are seasoned. This recipe uses smoked paprika, thyme, and black pepper to add flavor without adding sodium.

Is tempeh gluten free?

If you need a gluten-free option, tamari keeps the flavor bold without wheat. Many readers swap soy sauce for tamari in marinades or dipping sauces. Also check the ingredients list on the tempeh, some use grains.

Ways to Serve Air Fryer Tempeh 

Tempeh is versatile, and how you cut it can change both the texture and how it works in a meal. Different shapes work better for certain dishes, so slicing thoughtfully makes a big difference in cooking and presentation.

Stir-fries or sautés: Cut into thin strips or small cubes so it cooks quickly and absorbs sauces evenly.

Bowls or salads: Slice into thin rectangles or triangles to keep a nice bite-sized shape that sits well on greens or grains. I like the way this one looks the most!

Sandwiches or wraps: Cut into long, flat slices so it layers nicely and mimics deli-style protein. You can marinate and air fry for crisp edges. The TTLA at Whole Foods uses this cut. 

Crispy snacks or appetizers: Cut into small triangles or cubes, toss in seasoning, and air fry until golden for finger food or salad toppers.

Skewers or kebabs: Cut into thick cubes or rectangles that hold together on skewers without breaking apart during cooking.

Each cut changes texture, cooking time, and how it pairs with other ingredients. Adjust the size based on whether you want it soft, chewy, or crispy.
