Pad Thai is a Thai stir-fry of rice noodles tossed with a tangy-sweet tamarind sauce, egg, and savory additions, then finished with fresh sprouts, herbs, peanuts, and lime. It is a favorite across Thailand, including Koh Samui, though cooks and regions vary the protein, seasoning, and garnishes; this home version gives you the familiar balance without requiring specialist equipment.
Ingredients
- 6 oz (170 g) dried flat rice noodles, about 3 mm wide
- 2 tbsp (30 ml) tamarind concentrate, preferably unsweetened
- 1½ tbsp (22 ml) fish sauce
- 1½ tbsp (20 g) finely chopped palm sugar, firmly packed
- 1 tbsp (15 ml) water, plus 1–2 tbsp (15–30 ml) more if needed
- ½ tsp (1 g) crushed dried red chili flakes, or less to taste
- 8 oz (225 g) peeled, deveined raw shrimp
- 4 oz (115 g) firm tofu, drained and cut into ½-inch (1 cm) cubes
- 2 large eggs (about 100 g without shells)
- 2 tbsp (30 ml) neutral oil, divided
- 2 cloves garlic (about 6 g), finely chopped
- 1 small shallot (about 30 g), thinly sliced
- 1½ cups (135 g) fresh bean sprouts, rinsed and drained
- 1 cup (30 g) chopped garlic chives, cut into 2-inch (5 cm) lengths; or use sliced scallions
- ¼ cup (30 g) roasted peanuts, roughly chopped
- 1 lime (about 60 g), cut into wedges
Instructions
- Put the rice noodles in a large bowl and cover them with room-temperature water. Soak for 25 minutes, or until they bend easily but still feel firm in the center. Drain thoroughly. Avoid boiling the noodles at this stage: they will finish cooking in the pan, and noodles that are already soft can turn mushy when stir-fried.
- While the noodles soak, make the sauce and prepare the remaining ingredients. Whisk the tamarind, fish sauce, palm sugar, 1 tablespoon water, and chili flakes in a small bowl until the sugar dissolves. Taste a drop: it should be distinctly tangy, savory, and lightly sweet. Tamarind products vary in strength, so add a little water if the sauce is intensely sour, or a small pinch of sugar if it tastes sharp. Keep the shrimp, tofu, eggs, aromatics, and garnishes ready beside the stove.
- Heat a large wok or wide, heavy skillet over medium-high heat. Add 1 tablespoon oil and the tofu. Stir-fry for 2–3 minutes, turning the cubes until lightly golden on several sides. Transfer the tofu to a clean plate. Add the shrimp in a single layer and cook, turning once, until opaque and just cooked through, about 2–3 minutes depending on size. Check the thickest shrimp with a food thermometer; the USDA FSIS safe minimum for seafood is 145°F (63°C). Transfer the shrimp to the plate with the tofu.
- Reduce the heat to medium. Add the remaining tablespoon of oil, then the garlic and shallot. Stir for about 30 seconds, just until fragrant; do not let the garlic brown. Push them to one side of the pan. Crack in the eggs and scramble them gently on the open side until set. For egg safety, the USDA FSIS safe minimum for an egg dish is 160°F (71°C), checked with a food thermometer.
- Add the drained noodles and sauce. Toss and turn them with tongs for 2–3 minutes, separating the strands as they soften and absorb the sauce. If the pan looks dry before the noodles are tender, add water 1 tablespoon at a time. Keep the noodles moving so they cook evenly rather than sticking in a thick layer on the pan.
- Return the tofu and shrimp to the pan. Add about half the bean sprouts and half the garlic chives, then toss for 1 minute to warm them while leaving the sprouts crisp. If the noodles are still firm, add another splash of water and cook briefly; avoid adding a large amount at once, which can dilute the sauce and make the dish wet.
- Take the pan off the heat and taste a strand. Add a little more fish sauce for saltiness, a pinch of sugar for sweetness, or a squeeze of lime for extra brightness. Divide between two plates and top with the remaining sprouts, chives, and chopped peanuts. Serve immediately with lime wedges and extra chili flakes at the table.
Tips
- Choose the right noodles. Flat rice sticks around 3 mm wide are a good everyday choice. Very thin vermicelli can become fragile in a hot pan, while wide noodles need longer to soften. If your package gives soaking directions, use them as a guide but drain the noodles while they still have a little bite.
- Know your tamarind. Tamarind concentrate is convenient, but brands differ in tartness and salt. If you can only find a block of tamarind pulp, soak a small piece in hot water, mash it, and strain out the fibers and seeds; use the resulting thick liquid in place of the concentrate. Lime juice can add acidity in a pinch, but it tastes fresher and less rounded than tamarind, so the finished sauce will not have quite the same character.
- Keep the pan uncrowded. A wok or broad skillet gives moisture room to evaporate. If doubling the recipe, stir-fry in two batches rather than piling everything into one pan. A crowded pan steams the noodles and makes it harder to keep the shrimp tender.
- Adjust carefully. Fish sauce supplies salt and savory depth; soy sauce can replace it in the same amount for a fish-free version, but the flavor will be less distinctly Thai. Brown sugar can stand in for palm sugar, though it tastes slightly more molasses-like. Add either substitution gradually and taste before serving.
Serving Suggestions
Serve Pad Thai as soon as it leaves the pan, while the noodles are glossy and the sprouts still have crunch. Put extra lime wedges, chili flakes, and chopped peanuts on the table so each person can adjust the sourness, heat, and texture. A simple side of cucumber slices or lightly dressed greens is refreshing alongside the rich, savory noodles, but the recipe is substantial enough to serve on its own.
For a meal with a distinctly tropical island feel, pair it with fresh fruit such as pineapple or watermelon after dinner. Keep the plate uncluttered: lime, peanuts, and a little extra fresh bean sprout are the most useful finishing touches, and they let the sweet-sour sauce remain the focus.
Variations
For a vegetarian version, omit the shrimp and use 8 oz (225 g) tofu in total. Replace fish sauce with soy sauce, or use a vegetarian mushroom seasoning sauce if available; both change the flavor, with soy sauce giving a more direct salty taste and mushroom seasoning adding savory depth. Check that the sauce is suitable for your dietary needs.
Chicken can replace the shrimp. Cut 8 oz (225 g) boneless chicken into thin, even strips and cook it in the hot pan until the thickest pieces reach 165°F (74°C), the USDA FSIS safe minimum for poultry, checked with a food thermometer. Cook it before the egg and transfer it to a clean plate. For a milder plate, leave out the chili flakes and offer them at the table; for more heat, add a pinch to the sauce rather than scorching dried chili in the wok.
Garlic chives are traditional in many versions but may be difficult to find. Scallions are a practical substitute and provide a fresh onion note, though not the same gentle garlic flavor. Some cooks also use dried shrimp or preserved radish for extra savory complexity; these are optional additions, not requirements for a satisfying home batch.
Storage and Reheating
Pad Thai is best fresh because rice noodles firm up and lose some of their spring after chilling. Refrigerate leftovers within 2 hours in a shallow, airtight container, and keep them for 3–4 days. For the best texture, store any unused lime wedges separately and add fresh peanuts or sprouts after reheating rather than sealing them into the container.
Reheat only the portion you plan to eat. Add the noodles to a skillet with 1–2 teaspoons of water, cover briefly over medium heat, then toss until steaming throughout. You can also microwave them in a covered, microwave-safe dish, stirring halfway through and adding a small splash of water if they seem dry. Leftovers should reach 165°F (74°C), the USDA FSIS reheating temperature, checked with a food thermometer. Do not reheat the same portion repeatedly.
Frequently Asked Questions
Is Pad Thai from Koh Samui?
Pad Thai is a Thai dish enjoyed throughout the country, not a dish exclusive to Koh Samui. The island has its own food culture and access to seafood, but recipes vary from cook to cook; this version is a practical take on a widely known Thai noodle stir-fry rather than a claim to one island’s definitive style.
Can I make the sauce ahead?
Yes. Whisk the tamarind, fish sauce, palm sugar, water, and chili together and refrigerate in a covered container for up to 3 days. Stir it before using because sugar can settle. Taste again before cooking, since the acidity and salt level can differ among tamarind and fish sauce products.
Why are my rice noodles breaking or sticking?
Noodles usually break when they are soaked too long or tossed roughly after becoming very soft. If they stick, they may need a little more water or the pan may be too crowded. Drain them well, keep them slightly firm before they reach the wok, and use tongs to lift and turn rather than stirring aggressively.
Can I use cooked shrimp?
Raw shrimp gives you more control over texture and is cooked in the pan with the other ingredients. If using cooked shrimp, skip the raw-shrimp cooking step and fold it in near the end just long enough to heat through; prolonged cooking can make it tough. Follow safe handling directions for the shrimp and refrigerate leftovers promptly.
Is Pad Thai gluten-free?
Rice noodles are naturally made without wheat, but fish sauce, soy sauce, tamarind products, and packaged seasonings can vary. Check each label for gluten-containing ingredients or cross-contact warnings. If replacing fish sauce with soy sauce, choose a gluten-free soy sauce or tamari when needed.
Can I cook the whole recipe in advance for guests?
This dish is at its best straight from the pan, so prepare the sauce, chop the garnishes, and soak and drain the noodles ahead, then stir-fry just before serving. If cooking earlier is unavoidable, cool and refrigerate it promptly, then reheat to 165°F (74°C); expect softer noodles and less-crisp sprouts.
