What Is Stir-Fried Morning Glory (Pak Boong Fai Daeng – ผัดผักบุ้งไฟแดง)?

Stir-Fried Morning Glory or Pak Boong Fai Daeng (also Pak Boong Fai Dang), is one of Thailand’s most iconic street-side stir—fries fast, bold, and unbelievably flavorful.

The dish is made by flash-frying morning glory with garlic, chilies, and savory sauces over intense, smoking-hot heat. The name “fai daeng” means red fire, referring to the dramatic flash of flame that often erupts when the vegetables hit the hot wok. This high-heat technique keeps the greens crisp and vibrant while infusing them with smoky, garlicky depth. Simple, fragrant, and ready in seconds, pak boong fai daeng is a Thai classic enjoyed everywhere from street food stalls, restaurants and at homes best served piping hot with jasmine rice.

This was my first time making pak boong fai daeng, and yes I wanted that dramatic “fai daeng” flash of flame moment you see at Thai street stalls. The key is very hot pan, very hot oil, and a little water in the sauce to create that burst of flame. And honestly, I’m so happy with how this dish turned out.

A quick safety note: This method can be dangerous if you’re inexperienced, so you don’t have to attempt the flame-up technique at home. Just cook it on the highest heat your stove allows. You’ll still get delicious, vibrant pak boong without the fire show.

    Ingredient Highlight: Morning Glory (ผักบุ้ง – Pak Boong)

    Why It Matters

    Morning glory is the heart of this dish. This vegetable is crisp, juicy, and incredibly fast-cooking. Its hollow stems create that signature light crunch, while the tender leaves soak up the garlicky, savory sauce. In a flash-fried dish like pak boong fai daeng, morning glory delivers both texture and freshness in every bite.

    How It’s Used

    The stems and leaves are cut into long sections and cooked whole. Because morning glory cooks in seconds, it’s always added last and flash-fried over intense heat. The stems stay crunchy, the leaves wilt just enough, and the entire bundle absorbs the sauce beautifully without turning soggy.

    In Thai Cooking

    Pak boong (morning glory) is one of Thailand’s most beloved vegetables. It's used in stir-fries, soups, and even spicy salads. Its mild flavor pairs well with chilies, garlic, fermented soybean paste, and fish sauce. On the street, it’s famously tossed into smoking-hot woks, creating the dramatic “fai daeng” (red fire) flame this dish is named after.

    Tips Before You Start Making Stir-Fried Morning Glory (Pak Boong Fai Daeng)

    • Prep everything in advance: This dish cooks in 10–15 seconds, so all ingredients, morning glory, garlic, chilies, sauces, must be measured, cut, and combined before the heat goes on.
    • Use the hottest heat you can: Pak Boong Fai Daeng relies on intense heat for its smoky aroma. Most home stoves can’t match street stalls, but use your highest flame to get as close as possible.
    • Don’t overcrowd the wok: Cook one batch at a time. Too much morning glory at once will steam instead of flash-fry.
    • Keep your movements fast: This is a rapid stir-fry. Once it hits the wok, stir quickly and confidently, hesitation overcooks the greens.
    • Skip the flame-up at home: The dramatic “fai daeng” flash of fire may requires restaurant-level burners. It’s not necessary for homecook, and it can be unsafe. High heat without flames is more than enough.
    • Serve immediately: Morning glory loses its crisp texture if it sits too long. Plate and serve while it’s still sizzling.

    FAQs for Stir-Fried Morning Glory (Pak Boong Fai Daeng - ผัดผักบุ้งไฟแดง)

    Why is my morning glory not crisp?

    Your wok wasn’t hot enough. This dish needs extremely high heat so the greens sear quickly without steaming. Make sure the wok and oil are smoking hot before adding anything.

    Can I use a regular pan instead of a wok to make stir-fried morning glory?

    Yes, but use the highest heat your stove allows. A wok gives better aroma and faster searing, but a large sauté pan can still produce great results.

    Why do restaurants get that big flame?

    Because they use commercial high-BTU burners that blast out extremely intense heat. Most home stoves can’t reach that level, so the dramatic “fai daeng” flame-up you see at street stalls and restaurants usually won’t happen and if it does, it’ll be a smaller flame.

    Can I skip fermented soybean paste when making stir-fried morning glory?

    You can, but it adds a savory depth and subtle funk. If you skip it, add a touch more oyster sauce to compensate.

    Why do I need to prep everything in one bowl before I cook stir-fried morning glory?

    Because the dish cooks in 10–15 seconds. There’s no time to measure or grab ingredients once the wok gets hot. Everything must go in at once.

    Can I make stir-fried morning glory less spicy?

    Yes. Reduce the number of chilies or remove the seeds for a milder flavor.

    Can I make vegan stir-fried morning glory?

    Yes. Swap oyster sauce for mushroom oyster sauce and use light soy sauce instead of fish-based sauces.

    Can I reheat stir-fried morning glory?

    You can but morning glory loses its crisp texture when reheated. It’s best cooked and served immediately.
