Air-Fryer Green Beans

One base method for crisping green beans, then swap the seasoning each night. I worked these out in a convection toaster oven; a basket air fryer runs a bit different — notes below.

Ingredients

Per portion (scales up — just keep them in a single layer):

100g green beans, trimmed
1.5 tsp neutral oil (veg or canola; olive works too)
salt and pepper
one of the flavorings below

Steps

Part 1: Prep ahead

Trim the beans
Portion ~100g into containers and refrigerate — they keep about 5 days raw. Use a slightly oversized container so you can rinse and toss in the same one (fewer dishes).

Part 2: Cook

Convection toaster oven:

Preheat to 425°F, super convection on
Rinse the beans and dry them with a towel (you can rinse in the storage container, just dry it after too)
Toss the dried beans with the oil until lightly glossy (no oil pooling), then add salt, pepper, and any “before” seasonings for your flavoring
Spread in a single layer with space between them
Cook ~12 min, until shriveled and browned in spots with a tender-snappy bite
Add any “after” finish off the heat

Basket air fryer (untested here): same method, but shake once or twice since the beans sit in a solid basket. Air fryers crisp faster and more evenly, so try 400°F and start checking around 8 min.

Flavorings

Pick one per batch. Before = toss on with the oil before cooking. After = off the heat once they’re done.

Smoky paprika-cumin — bold, earthy

Before: 1/8 tsp each smoked paprika, garlic powder, ground cumin
After (optional): a squeeze of lime

Verdict: Amazing, I could eat this every day.

Lemon-oregano-garlic — bright, herby

Before: 1/8 tsp each garlic powder, onion powder, dried oregano
After: a squeeze of lemon. It relies on the acid, so if it tastes flat add more lemon, not more spice.

Verdict: Also amazing and I could eat this every day.

Cumin-lime — warm and tangy (UNTESTED)

Before: 1/8 tsp each ground cumin and garlic powder, plus a lighter pinch of smoked paprika
After: a squeeze of lime

Soy — mild, savory

Before: oil only, no salt (the soy salts it)
After: ~1 tsp soy sauce. For a little sharpness, whisk it with 1/4 tsp mustard powder first.

Verdict: This was fairly mild but good. In the recipe above I increased the mustard powder to try and make it more interesting.

Chili-flake — smoky and hot (UNTESTED)

Before: the smoky paprika-cumin mix above
Last 2–3 minutes: a pinch of chili flakes. Add them late or they turn bitter over a full cook.

Sesame-soy — nutty, savory

Before: oil only, no salt
After: ~1 tsp soy sauce, a drizzle of toasted sesame oil, and a pinch of chili flakes. Sesame oil is a finishing oil — don’t cook with it, it burns and turns bitter. Basically restaurant sesame green beans, and a good fix for the plain-soy version tasting flat.

Verdict: This was much better than soy and mustard! I used Aleppo flakes, but that wasn’t spicy enough.

Harissa — complex, a little spicy

Before: ~1/4 tsp dry harissa blend, tossed on with the oil like the other rubs. It’s chili-forward, so if yours runs hot, add it partway through or keep the cook shorter — ground chilies turn bitter over a long, hot cook. Caraway and coriander give it a different character from the smoky rub.

Verdict: I did a heaping 1/4 tsp and it wasn’t quite flavorful enough for me. Next time I’ll try more.

Tips

Don’t crowd them — crowded beans steam instead of blister, so two rounds beats one packed layer.
Store raw, not cooked. Crisped beans go soft in the fridge, so portion them raw and crisp a fresh batch each time. That’s the trick to having them most nights without much work.
Before vs. after: dry spices and garlic/onion powder go on before, with the oil. Anything acidic, liquid, or delicate — lemon/lime, soy, chili flakes, fresh herbs — goes on late or after, or it burns.
Salt before is fine and spreads more evenly. The exception is the soy finishes, since the soy’s already salty.
Oil: neutral oil handles the heat best. Olive usually works; if it smokes or tastes bitter, switch oils or drop to 375°F.
