Best Thai Restaurants in London: The Art of Perfect Pad Thai at Thai Square

Pad Thai is Thailand’s culinary ambassador to the world. This seemingly simple dish of stir-fried rice noodles has captured hearts globally, yet few restaurants outside Thailand truly master its complex balance. At Thai Square, recognised as one of the best Thai restaurants in London, we honour the authentic techniques and traditional flavours that make Pad Thai a masterpiece of Thai cuisine.

The Fascinating History Behind Thailand’s National Dish

Surprisingly, Pad Thai is a relatively modern creation. In the late 1930s and early 1940s, during Prime Minister Plaek Phibunsongkhram’s administration, Thailand faced rice shortages and sought to promote nationalism. The government launched a campaign to popularise rice noodles as a patriotic alternative to rice.

Pad Thai (literally “Thai-style stir-fried noodles”) was developed as part of this initiative, quickly becoming the nation’s signature street food. The dish cleverly balanced the four fundamental Thai flavours (sweet, sour, salty, and spicy) whilst being economical to produce and easy to eat on-the-go.

What began as government policy transformed into cultural icon. Today, Pad Thai represents Thai cuisine internationally, and at the best Thai restaurant London offers, Thai Square serves it with the respect and authenticity this historic dish deserves.

The Essential Components of Authentic Pad Thai

Perfect Pad Thai is about harmony. Each component must be precisely prepared and balanced with the others. Here’s what makes authentic Pad Thai special:

The Noodles

Authentic Pad Thai uses sen lek, flat rice noodles about 3-5mm wide. At Thai Square, we source premium rice noodles that achieve the perfect texture: tender yet slightly chewy, with enough body to hold the sauce without becoming mushy.

The noodles must be properly hydrated before cooking. Too dry and they break; too soft and they turn to paste in the wok. This preparation is where authentic technique makes all the difference.

The Sauce

The sauce is Pad Thai’s soul. Traditional Pad Thai sauce requires:

Tamarind paste: This provides the essential sour note. We use fresh tamarind pulp, never bottled substitutes. The tartness must be bright and complex, not flat or one-dimensional.

Palm sugar: Traditional sweetness comes from palm sugar, which offers caramel-like depth that regular sugar cannot match. The sweetness should balance the tamarind’s tartness perfectly.

Fish sauce: This provides the salty, umami foundation. Premium fish sauce (made from anchovies fermented for months) delivers complexity that table salt simply cannot provide.

At Thai Square London restaurants, our chefs prepare Pad Thai sauce fresh daily, adjusting the balance of these three elements with the precision of master craftsmen.

The Protein

Traditional Pad Thai typically features prawns, chicken, or tofu. Each protein brings different qualities:

Prawns: Their sweet, delicate flavour complements Pad Thai’s sauce beautifully. They must be cooked quickly at high heat to remain tender and juicy.

Chicken: A popular choice that absorbs the sauce wonderfully. We use tender chicken breast sliced thin for even cooking.

Tofu: Authentic Pad Thai uses firm tofu, fried until golden to create textural contrast. It’s not just a vegetarian substitute but a traditional component that adds substance.

The Aromatics and Vegetables

Garlic and shallots: Stir-fried until fragrant, these create the aromatic foundation.

Dried shrimp: Ground dried shrimp adds a distinctive funk and umami depth that’s essential to authentic Pad Thai.

Preserved radish: Sweet preserved radish (chai poh) provides bursts of sweetness and crunch throughout the dish.

Bean sprouts: Fresh, crunchy bean sprouts are added at the end, providing cooling contrast and textural variety.

Chives: Chinese chives (or garlic chives) add a mild onion-garlic flavour and beautiful green colour.

The Garnishes

Proper Pad Thai comes with traditional accompaniments that elevate each bite:

Crushed peanuts: Roasted peanuts add richness, crunch, and nutty flavour that complements the sweet-sour-salty sauce.

Lime wedges: A squeeze of fresh lime adds brightness and allows diners to adjust acidity to preference.

Fresh chilli: For those who want additional heat, dried chilli flakes or fresh sliced chillies are provided on the side.

Additional bean sprouts: Extra fresh bean sprouts are served alongside for added crunch and freshness.

The Technique: Why Wok Skill Matters

Even with perfect ingredients, Pad Thai requires masterful technique. This is why authentic Pad Thai from the best Thai restaurant London has to offer, Thai Square, tastes fundamentally different from home-cooked versions.

High heat (wok hei): Professional Thai cooking uses extremely high heat that home stoves cannot achieve. This “breath of the wok” creates characteristic smoky notes and ensures ingredients cook quickly, preserving texture whilst developing flavour.

Speed and timing: From the moment ingredients hit the wok, the entire cooking process takes about 3-4 minutes. Timing each component’s addition is crucial: everything must finish cooking simultaneously at peak doneness.

The fold technique: Authentic Pad Thai isn’t just stirred, it’s folded. The chef uses a swift folding motion that coats the noodles with sauce whilst preventing them from breaking.

Single-serving preparation: At Thai Square, we prepare each Pad Thai individually to order. This allows precise heat control and ensures your dish arrives at the table at perfect temperature with ideal texture.

Common Pad Thai Mistakes and How We Avoid Them

Having served thousands of Pad Thai dishes as one of London’s premier Thai restaurants, we’ve identified what separates authentic from ordinary:

Mistake: Oversaucing
Authentic Pad Thai isn’t swimming in sauce. The noodles should be lightly coated, not drowned. Each strand should have flavour without becoming soggy.

Mistake: Wrong sweetness level
Western adaptations often make Pad Thai cloyingly sweet. The sweetness should be subtle, balanced by tartness and saltiness. You should taste complexity, not sugar.

Mistake: Overcooked noodles
Mushy noodles are Pad Thai’s death. Proper texture requires perfect hydration before cooking and precise wok timing.

Mistake: Missing the funk
Authentic Pad Thai has a characteristic funky quality from dried shrimp and preserved radish. Without these, it lacks dimension.

Mistake: Inadequate heat
Low heat creates steamed noodles rather than stir-fried ones. High heat is essential for proper texture and that wok-kissed flavour.

At Thai Square, our Thai-trained chefs avoid these pitfalls, delivering Pad Thai that honours its street food origins whilst meeting fine dining standards.

Pad Thai Variations: Traditional and Regional Styles

Whilst the classic Pad Thai described above is most common, Thailand offers interesting variations:

Pad Thai Kung Sot (Fresh Prawn Pad Thai): Features jumbo prawns as the star. The prawns are often butterflied and cooked to sweet, tender perfection.

Pad Thai Hokkien: Incorporates yellow egg noodles alongside rice noodles, creating additional textural interest. This variation shows Chinese influence on Thai cuisine.

Pad Thai Wrapped in Omelette: The finished Pad Thai is wrapped in a thin, crispy omelette, adding richness and beautiful presentation.

Pad Thai Goong Mae Nam (River Prawn Pad Thai): Uses massive freshwater prawns for a luxurious version of this humble dish.

At Thai Square’s extensive menu, we offer several Pad Thai variations, all prepared with the same commitment to authenticity that has earned us recognition as one of the best Thai restaurants in London.

The Health Benefits of Authentic Pad Thai

When prepared authentically with quality ingredients, Pad Thai offers nutritional benefits:

Quality carbohydrates: Rice noodles provide energy without gluten, making Pad Thai naturally gluten-free.

Lean protein: Prawns and chicken offer high-quality protein with relatively low fat content.

Beneficial fats: Peanuts provide healthy monounsaturated fats, vitamin E, and minerals.

Fresh vegetables: Bean sprouts and chives contribute vitamins, minerals, and fibre whilst adding minimal calories.

Probiotic elements: Fermented fish sauce and preserved radish contain beneficial bacteria that support gut health.

Of course, like any delicious food, Pad Thai is best enjoyed as part of a balanced diet. The dish’s perfect balance of flavours ensures satisfaction without excess.

Pairing Pad Thai with Other Thai Dishes

In Thailand, meals are communal affairs featuring multiple dishes shared among diners. Pad Thai pairs beautifully with:

Tom Yum soup: The hot and sour soup provides refreshing contrast to Pad Thai’s sweet-savoury richness.

Som Tam (papaya salad): Fresh, spicy, and crunchy, Som Tam cleanses the palate between bites of Pad Thai.

Thai spring rolls: Light, crispy spring rolls offer textural variety alongside the soft noodles.

Thai iced tea: The sweet, creamy beverage complements Pad Thai’s complex flavours whilst providing cooling relief.
