Homemade Medicinal Garlic Sauce Recipe

In our kitchen, we almost always have a batch of this sauce on hand. We store it in the refrigerator and pull it out as needed. It is delicious spread onto toast or bagels and topped with fresh tomatoes and chickweed. This sauce is a convenient way to add fresh garlic to dishes just before serving. Baked fish, home fries, and roasted roots are all enhanced by this tasty sauce.
Course Sauce
Yield 1.5 cups


  • ¼ cup garlic, finely minced - 1 bulb = approximately a ¼ cup.
  • 1 cup extra-virgin olive oil
  • 1 teaspoon sea salt
  • ½ cup nutritional yeast


  • You can substitute grated Parmesan cheese for the nutritional yeast if you’d prefer, and omit the salt.
  • Mix all ingredients by hand and refrigerate.
  • Use within one week.


We recommend refrigerating this sauce. This is to reduce the chance of bacterial contamination, namely the botulism bacteria (Clostridium botulinum). Oil infusions create an oxygen-free environment where botulism spores will thrive if given a chance, and the water contained in fresh herbs can introduce these bacterial spores. Nonetheless, some people prepare culinary oils with fresh herbs, but we caution against it because the results can be deadly. More on fresh herbs and the risk of botulism.

  1. We love garlic here too! Any tricks to not have “dragon breath” from lots of raw garlic though? Whenever colds are going around, I give the kids fresh minced garlic mixed with honey and cinnamon – they love it – but we all give each other a bit more breathing space! I’d like to boost our immune systems a bit without scaring visitors away 🙂

      Hello fellow garlic lover! I have heard that eating apples or mint after you consume garlic could neutralize the odor, but I have not tried it myself. If you give it a try, let us know how it goes 🙂

    • Christine Borosh says:

      Botulism can thrive in an anaerobic environment like within oil, even in the refrigerator. We recommend using up the sauce within a week to be cautious due to this safety concern.

  2. Linda F Ballinger says:

    I want to try this garlic recipe to add to my immune arsenal. Another that is sweet and spicy is garlic honey. two of my favorite healthy foods. Thank you for the recipe.

  3. What a fantastic recipe! I love garlic for its antioxidant and antimicrobial properties but struggle with taking garlic tincture. I definitely will be giving this a go! Thanks for sharing 🙂
