📋 Ingredient Notes
Brussel Sprouts – These miniature cabbages are the key base of this dish.
Salt – Essential for the base flavor of any great roasted brussels sprouts recipe
Olive Oil or Cooking Spray – I prefer to use cooking spray to cook small batches of this dish. If cooking a bigger batch for a group dinner, feel free to opt for olive oil.
Fish Sauce – A key ingredient for that delicious signature Thai flavor. Don’t be put off by the smell! I would not recommend omitting this ingredient, and there are not really any good substitutes. You can easily pick up fish sauce at most major grocery stores or order from Amazon. Three Crabs Fish Sauce is my favorite brand.
Thai Sweet Chili Sauce – This is a typical sweet chili sauce common in Thai cuisine. You can find it at your local Asian market or online. If you don't have any, feel free to substitute with some maple syrup or brown sugar, but the flavor won't quite be the same.
Cashews – Adds some crunch to the dish. You can also opt to use peanuts, or omit them.
Red Pepper – I used a mini red bell pepper. You can also opt to use Thai chilis to make it even more Thai, but keep in mind that Thai chilis are extremely spicy, and I didn’t want to give my dinner guests an unwelcome surprise.
Lime wedges (Optional) – Garnish with some lime wedges and drizzle them over the brussels sprouts for some freshness

Line the parchment paper on the air fryer – This will make cleaning the air fryer significantly easier. In most cases, it will just be a matter of throwing out the parchment paper.
Roast the brussels sprouts in a single layer – Not doing so will result in inconsistent roasting. Make sure to lay in a single layer with some space in between.
📖 Substitutions and Variations
Thai chilis for spicier sauce – Use 1 for a mild spice, and 2-3 for a heavier kick.
Peanuts instead of cashew – Peanuts are a great substitue for cashews as a garnish.

💭 Frequently Asked Questions
If your brussels sprouts are still hard, it's likely they haven't been roasted for long enough. Add them back into the oven, air fryer, or cast iron for a couple of minutes at a time, and check in on them regularly until they've reached the desired crispness.
Cut them lengthwise and cut off the bottoms. If a particular sprout is too big, cut it into quarters to ensure consistency in roasting.
🥡 Storage
You can store these brussels sprouts in an airtight container in the fridge for up to 3 days.
If you’re making this ahead of time for a holiday party, hold off on the garnish. Add the garnish and some additional sweet chili sauce before serving.
