If a Vietnamese dish feels like it’s “missing something,” it’s usually the peanuts. These are the golden crowns for everything from Bún Thịt Nướng to Gỏi Cuốn. Learning how to roast peanuts in an air fryer is the ultimate kitchen hack to get that essential smoky, nutty contrast that cuts through the richness of grilled meats and the tang of our 3-2-1 dipping sauce.
The HCMC Street Side
Growing up in HCMC, the smell of roasting peanuts is everywhere—it’s the scent of the street food stalls. While the traditional way involves a wok and a bed of salt, I’ve modernized the process for our busy lives in the West. This Air Fryer Roasted Peanuts recipe gives you that same nostalgic crunch in a fraction of the time, with zero standing over a hot stove.
What is Đậu Phộng Rang?
These are skinless, blanched peanuts that have been dry-roasted until they are deeply golden and crisp. In Vietnamese roasted peanuts, we don’t just use them for flavor; we use them for “texture architecture.”
Key Things to Know Before You Start
- The “Carry-Over” Rule: Peanuts continue to cook for 2–3 minutes after they leave the heat. If they look “perfect” in the Air Fryer, they might be burnt by the time they cool!
- Blanched is Best: To save time and get that clean, professional look, start with pre-peeled and blanched peanuts.
- The Smash Technique: Don’t use a blender! A manual smash creates different sized pieces that provide a much better eating experience.
Ingredients & Substitutions
- Peanuts: 1–2 cups of raw, blanched (skinless) peanuts.
- The Tools: An Air Fryer and a Mortar & Pestle (or a silicone bag and kitchen mallet).
How to Make Roasted Peanuts – Step-by-Step Instructions
- Air Fry: Spread the peanuts in a single layer in your Air Fryer basket. Set to 320°F for 11–12 minutes.
- Shake: Give the basket a good shake halfway through to ensure an even, golden tan on all sides.
- Cool: Pour the peanuts onto a flat plate immediately. Let them cool completely—they won’t get fully crunchy until they are cold!
- The Smash: Place the cooled peanuts in a mortar and pestle or a silicone bag. Lightly hit them with a kitchen mallet until they are broken into irregular, rustic pieces.
Tips for Success & Mistakes to Avoid
- Low and Slow: 320°F is the “sweet spot.” Anything higher risks burning the outside while the inside stays raw and chewy.
- The “Mallet” Secret: Smashing them manually preserves the natural oils better than a food processor, which can turn them into a greasy paste.
- Avoid Moisture: Never store your peanuts while they are still warm, or the steam will make them soggy in the jar.
Serving, Storage & Make-Ahead Suggestions
- Serving: Sprinkle generously over Noodle Bowls, Bánh Bèo, or as a topper for your peanut sauce for Gỏi Cuốn!
- Storage: Keep in an airtight glass jar at room temperature for up to 2 months.
- Make-Ahead: I always roast a big batch every month so I have that “instant crunch” ready for my weekday meals.
FAQs
- Can I use an oven? Yes, but the Air Fryer’s circulation is much more efficient. If using an oven, go for 325°F and stir every 5 minutes.
- Why are my peanuts soft? They likely haven’t cooled down yet. Give them 15 minutes on the counter and they will crisp right up!
