How to Make Authentic Thai Curry with Store-Bought Paste

Making authentic Thai curry with store-bought Thai curry paste is one of the most rewarding one-pot meals you can master. Despite what high-end cookbooks might suggest, it isn’t a complex, multi-hour ordeal. In fact, if you’ve ever felt intimidated by the long list of ingredients in a homemade paste, here is a secret: your favorite local Thai restaurant almost certainly uses a high-quality premade paste as their base, and you can, too.

The Thai Curry Purity Myth: Why “Homemade” Isn’t Always Better

There is a persistent myth in the West that if you don’t pound your own curry paste from scratch, your dish isn’t “authentic.” The implication is that a homemade paste is automatically perfect, while store-bought is an inferior shortcut.

In reality, high-quality brands like Maesri or Mae Ploy are often superior to what a home cook can produce. These pastes are made with fresh, local ingredients at the source, ingredients that are often difficult or impossible to find at a standard U.S. grocery store.

But here is the most important truth: The work doesn’t stop once the paste hits the pan. Whether you spent an hour with a mortar and pestle or five seconds opening a tin, the final flavor depends on you. A paste is a foundation, not a finished program. You still have to taste and adjust for heat, citrus, salt, and pungency to make it your own.

Authenticity isn’t about how long you pound the paste; it’s about understanding the essential Thai cooking ingredients and how they interact in the pot.

Thai Curry Paste is a Base, Not a “Quick Mix”

Perhaps the biggest hurdle for Western cooks is the name. We tend to treat “curry paste” like a packet of instant taco seasoning, a “quick mix” that contains everything needed for a finished dish. It doesn’t help that Thai curry “sauces” are sold that could easily be confused with a paste.

In reality, curry paste is a seasoning and flavoring base, much like a Latin sofrito or a French mirepoix. It is a concentration of aromatics designed to be fried in fat to release their oils. Just as you wouldn’t expect a jar of sautéed onions and garlic to be a finished soup, you shouldn’t expect a tin of Maesri or Mae Ploy to be a finished curry. It provides the DNA of the dish, but you are the one who provides the life.

Best Store-Bought Thai Curry Pastes

You can make a great curry with any number of premade pastes. The best choices are Maesri Thai Curry Paste and Mae Ploy. ,

Mae Ploy curry paste is also a very good brand that I use often. It is much more convenient. The paste has much less moisture and comes in large tubs (the paste is actually in a plastic bag inside the tub). It lasts for months in the refrigerator, still retaining flavor and aroma well.

Maesri Thai Curry Paste: This is your “Flavor Punch” base. Because it includes dried spices like coriander seeds, cumin, and cardamom, it has a more complex, aromatic profile right out of the tin. It’s also vegetarian-friendly (no shrimp paste), which makes it a versatile “blank canvas.” Maesri comes in a 4-pack of smaller cans. Maesri makes red, green, yellow, Masamam, and Panang Thai curry paste.

Mae Ploy Curry Paste: This is your “Heat and Depth” base. It is significantly hotter than Maesri and includes shrimp paste, which provide a savory, pungent richness. Because the heat is so high, it requires a more deft hand with “Reinforcement”—you have to be careful not to add too much paste in a quest for flavor, or you’ll end up with a dish that is “all fire and no soul.”

The heat of the Mae Ploy makes it more difficult to develop flavor without an overwhelming spice, and without the addition of additional flavoring ingredients, but with practice, both brands make very good curries. You may like one better than the other. The Mae Ploy makes a more forgiving base but requires more enhancement to complete the flavor profile, while Maesri’s heavy emphasis on dried spice may overwhelm you from the beginning, but requires less finesse for a complete curry.

Some other brands to look for are Pantai Norasingh, Nittaya, and Lobo.

Which Paste Should You Buy First?

If you are standing in the aisle of an Asian market staring at a rainbow of Maesri or Mae Ploy tins, start with Red Curry Paste.

Red curry is a workhorse of Thai cuisine. It forms the flavor basis for a vast majority of dishes and is likely the most familiar profile to Western palates (alongside the milder Massaman). The rule of thumb for beginners is simple: Start with the curry you’ve eaten most often in restaurants. Familiarity is your best tool for reinforcing flavors because you already have a mental map of what the finished dish should taste like.

While you’re picking out your paste, make sure you have the right foundation for the bowl. Check out my guide on what kind of rice you need for Thai food to complete the meal.

Coconut Milk

You’re going to need some coconut milk. However, at the beginning of most recipes, you’ll see coconut cream or oil. No, you don’t need to get a separate product, the coconut cream is the more solid and creamy stuff you’ll find at the top of the can of coconut milk. This is mostly fat and can be used in place of oil to start your curry.

If you prefer to use the cream, which I recommend, you’ll need to by your coconut milk in cans. AVOID coconut milk with added guar gum or your finished curry will have an overly thick “gummy” consistency. I’ve ruined Thai curries by mistakenly buying coconut milk with guar gum. Read the ingredient listing. Do expect, however, some preservatives.

If your can of coconut milk hasn’t separated and there is no cream at the top, use a neutral oil like canola oil or grapeseed oil. However using the “cream” which is mostly coconut fat, is much better. Since the coconut mile is already such high fat, having to start with another oil means you will only want to use a small amount, especially the added oil will make your curry more “oily.”

However, it’s best to be able to start with as much fat as possible. By using the cream, you get a lot of fat, which will work much better for pre-frying the paste and waking up the aromatics.

When opening a can of coconut milk, do not shake it! Hopefully, it’s been sitting around enough that the cream has separated and formed a semi-sold layer at the top. Since you can’t be sure, the best method is to prepare in advance. Pour the coconut milk from the opened can into an airtight container and place it in the fridge at least a day before you need it. This will speed up the cream rising to the top, a semi-fluid layer that is more like a paste than a liquid.

Sweetener

A Thai curry usually has a bit of sugar added for balance. Although palm sugar is traditional, you can use plain white or brown sugar, or you could experiment with other sweeteners. Be aware that certain strong flavors will never work. You cannot use honey to sweeten your curry as the taste will clash and take over the other sweet flavors already present.

Kaffir Lime: Alternatives and Awareness

Kaffir lime peels and leaves are often touted as “indispensable” in Thai curry. They are often used in the curry paste base and are also added to the curry to reinforce or add a complex citrus flavor While they provide a unique aroma, they are also difficult to find fresh in the U.S., and the dried versions often lack the brightness needed to lift a dish.

Beyond the culinary aspect, there is a significant social reason to reconsider the name. The term “kaffir” carries heavy racist connotations, particularly in South Africa, and many chefs now prefer the term Makrut lime.

The Pro Fix: Don’t let the lack of a specific leaf stop you from cooking. As I explain in my guide on Kaffir lime and its substitutes, a blend of fresh lime and lemon zest is a fantastic alternative. And, while fresh kaffir limes add an aroma and pungency not found in lime zest, you may find you don’t miss it when when compared to the bright citrus zing of lime zest. You can also use both! I don’t feel a Thai curry is done without some zest and lime juice.

Vegetables for Thai Curry

You can put in the vegetables you like, and you might already have an idea based on what you’ve had before at a Thai restaurant. But I’ll tell you the three vegetables that I like to have in for that “everyday” curry: bamboo shoots in strips, red bell pepper, and long beans (use green beans to substitute, cut into julienne).

The long bean is like an overgrown string bean (green bean). The taste is similar and you won’t have any trouble substituting green beans, but long beans have more crunch, and they cook up faster. The two beans are of a different genus. If you have an Asian or Thai store nearby, and they have long beans, buy them for your curry. Pick darker beans without big bumps as the bumps indicate larger bean seeds inside (the smaller the bean seeds the better).

If you can’t buy them locally, then use fresh green beans. You can order long beans, but you can’t expect to get the beans you’d have picked yourself this way, nor have I ever ordered fresh beans online myself.

Fish Sauce

A Thai Curry is given a bit of a pungent boost by the addition of a little fish sauce. A little goes a long way!

The Basil Breakdown: Thai vs. Holy

Another ingredient that will make your Thai curry more authentic and give it that final herbal and citrus push, is Thai Basil or Holy Basil. These both are NOT the same as our familiar Western basils.

Thai Basil (Horapha): This is the most common variety you’ll see in Red or Green curries. It has purple stems and a distinct anise or licorice flavor. It’s sturdy and holds up well to the heat of the curry.
Holy Basil (Kraphao): This is the star of “Stir-fry” dishes like Pad Kraphao, but it occasionally finds its way into spicier, water-based curries. It has a peppery, clove-like punch. Crucially, Holy Basil wilts and loses its flavor almost instantly, so it must be the very last thing to hit the pot.
The Pro Basil Tip: I have tried to substitute Italian Sweet Basil in my Thai curry and the result was overpowering. It tasted more like “Italian” than “Thai.” So, if you can’t find Holy Basil at your local market, Thai Basil, or even a small amount of fresh mint, to keep that sharp, Southeast Asian profile. Mint is widely used in Thai cooking.

My Curry is Not Spicy (Hot) Enough

If you are like me, and love your Thai food extra spicy, you may have trouble getting the pungent heat you want into your curry. You could add more paste, since it contains chiles, to try to increase the spiciness, but there comes a point where you will have added more paste than is adequate to produce a balanced flavor.

The solution to making your curry more spicy hot is to add more chili pepper, not more paste. You may be able to get some dried, or even fresh Thai chiles from a Thai, or mixed Asian market.

Some good substitutes for these chilis are chiles de arbol, pequin, or even habanero (hotter than the others). De-seed the chiles and just stew them in the curry to allow them to release some heat. Do not chop them up unless you like to have chunks of whole chili peppers to eat. A little goes a long way, so sometimes only one or two chiles will do the trick. If you’re using habanero, use only a small bit in the beginning!

You can reinforce the flavor of any ingredient used in the curry paste by adding more of that particular ingredient.
