    Thai basil sauce in a skillet with text overlay "all-purpose Thai basil sauce"

    I LOVE all kinds of basil, but I don't love how quickly it goes bad and that it doesn't freeze well. So I came up with this recipe as a way to use up any amount of basil you have on hand. It's an easy and versatile sauce that only uses pantry staples, and can be stored in the fridge for at least a week. Reheat it and pour onto any cooked protein, or use it as a stir fry sauce - or heck, you can even use it as gravy for your mashed potatoes. It can also be made vegan. The possibilities are endless!

    What is Thai Basil Sauce?

    If you go to any Thai restaurant in N. America, you might find something on the menu that is a stir fry in a brown sauce with Thai basil. It might be called pad kra pao, pad gaprao, or pad kra pow or something else. It's super popular, and I've seen renditions of this dish made with just about every protein: meat, seafood, tofu - and it all works well. The versatility of this dish is what gave me the idea for the sauce.

    This basil sauce will make whatever you put it on taste just like what you get from your Thai restaurant, but better, because you made it 😉

    Ingredients You'll Need

    Here are all the ingredients you'll need to make Thai basil sauce. Use whatever kind of basil you have + some simple pantry staples, which is the whole idea - and the peppers are optional!

    • Unsalted pork stock, chicken stock or vegetable stock
    • Red bell pepper or other sturdy vegetable such as mushrooms, carrots or celery (optional)
    • Garlic
    • Onion
    • Thai chilies (optional) or ground black or white pepper
    • Oyster sauce (or vegetarian oyster sauce)
    • Soy sauce
    • Fish sauce (or sub with more soy sauce)
    • Sugar
    • Thai basil or any other kind of basil - however much you have to use up!

    Step-By-Step:

    Here's a bird's eye view of the process, but be sure to check out the full video tutorial in the recipe card below for extra tips to ensure success!

    1. Sauté onions until translucent. Then add garlic and Thai chilies and saute until garlic is golden.
    2. Add the stock.
    3. Add all the sauces and seasonings.
    4. Add black/dark soy sauce to darken colour, if desired.
    1. Add bell peppers and cook for a minute, then add basil.
    2. Off heat, stir just until wilted.
    3. When ready to use, reheat and pour over cooked protein, or...
    4. Use as a stir fry sauce!

    Cooking As a Preservation Method

    The basic idea behind this recipe is the fact that cooking is a preservation method. A short-term preservation mind you, it's not like canning, but it can still buy you enough time so you don't have to waste anything.

    I do this often with vegetables. Ever got excited by a sale at the grocery store and bought too many vegetables? Now they're sitting in your fridge, about to die, and you still don't have any plans for them? If they don't freeze well, or you don't want to freeze them, you can just cook them! Cooking will stop the spoilage, and now it'll last in the fridge for at least another week, ready to be incorporated into your next meal when you're ready.

    With vegetables, you can simply steam, blanch, or saute them with a little salt. Cool them down quickly and pack it away. All ready-to-eat foods should last in the fridge for at least a week (given that your fridge is at the proper temperature). Steamed veggies can be tossed into a stir-fry, added to soups or stews, or simply mixed with a dressing such as this awesome Japanese deep roasted sesame dressing that is good on literally every possible vegetable.

    And if for some reason the week is over and it's still there? You can still freeze the cooked veggies, and they'll still be good for adding into soups or anything where a firm texture isn't important.

    How to Use the Basil Sauce

    There are 2 main ways to use this sauce: as a pour-over, or as a stir-fry sauce. The flavour works well in many dishes, but here are some things I have tried and love:

    • Pour-over sauce for fish (mackerel and halibut)
    • Pour-over sauce for fried tofu
    • Stir-fry sauce for chicken and veggies

    You can also get creative. I think the sauce would make a great gravy for mashed potatoes! What else do you think you could try?

    Frequently Asked Questions

    What kind of basil can I use with this recipe?

    This recipe will work with any kind of basil. I used Thai basil, but Italian or holy basil will work just as well.

    How can I make a vegetarian basil sauce?

    You can substitute the oyster sauce with vegetarian versions of oyster sauce; see this post for more on that. You can also use vegetarian fish sauce or substitute equal amount of soy sauce, Golden Mountain Sauce, or Maggi Seasoning.

    How long will the sauce last in the fridge?

    The sauce will last at least one week in the fridge.

    Can the sauce be frozen?

    In theory, yes, but the basil will not look as good and the basil flavour will not be as strong. If you want to freeze, I recommend leaving out the bell pepper and adding them in when you cook so that it will remain crisp, as vegetables turn soft after freezing.

    Notes

    1. To make this vegetarian, use vegetarian oyster sauce and substitute more soy sauce for the fish sauce.
    2. The amount given is a suggestion, but this recipe is designed to use up whatever you have. If you use less, it'll be a milder basil flavour. If you have more, you can pack it all in, or scale up the recipe accordingly.

    Instructions
     

    • Combine the oyster sauce, soy sauce, fish sauce and sugar together in a bowl.
      2 Tbsp oyster sauce, 1 Tbsp soy sauce, 2 tsp fish sauce, 2 tsp granulated sugar
    • In a wok or a skillet, heat the oil over medium heat. Add the onions and saute until soft and translucent, about 5 minutes. To help the onions cook faster you can add a splash of water and close the lid to allow it to steam for a minute. Then uncover and cook until all the water has evaporated.
      2 Tbsp neutral oil, ½ an onion
    • Once the onions are soft and translucent, add the garlic and Thai chilies and stir until the garlic starts to brown.
      6 cloves garlic, 1-2 Thai chilies
    • Add about ¾ cup (180 ml) of the stock, the sauce mixture, and ground black or white pepper then stir to mix. If you want to darken the colour, add a dash of black/dark soy sauce.
      1 cup chicken, pork, or vegetable stock, ground white or black pepper, ½ tsp black or dark soy sauce
    • Add the bell pepper and cook for about a minute, then turn off the heat and stir in the basil just until wilted. Taste the sauce, and if it is too salty, add the remaining stock or water to dilute; however, it should taste slightly too salty at this point because you will be adding protein to it.
      ½ cup julienned red bell pepper, 1 ½ cup basil leaves of any kind
    • Use right away, or allow to cool and keep in the fridge for at least a week. When ready to use, reheat the sauce and pour over pan seared protein such as fish, thinly sliced steak or pork chops - or use it as a stir fry sauce! Watch the video for a demo of how to use the sauce!

      Soooo delicious and easy! Used it to top sliced chicken breast meat. I wanted to lap up the leftover sauce from my plate! (Maybe I did, maybe I didn’t. 😉 Will definitely make again. Thank you!!

        I made the sauce and used it to make Drunken Noodles, a dish I get at my favorite Thai restaurant. Added shredded rotisserie chicken, noodles and scrambled eggs. It was very close to the restaurant version. I used low sodium chicken stock and soy sauce and felt it could have used a touch more Fish sauce. Will definitely make again!

      So yummy! I was recently diagnosed as celiac, which means my favorite Thai basil eggplant takeout is now off limits. Thank you for a wonderful recipe - I will be making this often with GF oyster sauce and tamari!

      This looks delicious, but Thai basil and regular basil for that matter will keep just fine if you trim the ends with a scissor and plunk them into a jar or glass of water. Not only that, they will start to grow roots and thrive as a houseplant or even an outdoor plant! The Thai Basil growing in my garden this summer came from a cutting that came with some takeout food in the spring, and I intend to keep some growing indoors all winter long.Even if I didn't cook with it, the smell is incredibly invigorating.

      I made this last night with fresh Thai basil harvested from our garden. I mixed in cooked ground beef, green beans, carrots & peppers and the flavor was out of this world. Really amazing and pretty easy and quick. I can't wait to make it again. My husband raved!! Thank you!

      Great recipe. I had to substitute serrano and habenero peppers but still turned out great. I also used honey instead of granulated sugar but a great technique/base recipe using what I had on hand.

      One of the worst things this gardener faces is pulling up and throwing out a bushy basil plant which has come to the end of its life. Now I know how to use up the remaining leaves in a delicious sauce. This more than just cooking and eating Thai food — it’s gaining skills to improve my life, help lower costs and reduce waste!
