Bring a medium saucepan to medium-low heat (a setting of 3 out of 10). Add the olive oil and allow it to warm through. Add the minced garlic and cook, stirring frequently for 1-3 minutes. Do not allow to brown.
Increase the temperature slightly and add the white wine. Simmer, stirring occasionally until it no longer smells of wine, about 3-5 minutes.
Add the butter, lemon zest, and lemon juice. Stir and allow the butter to melt.
Add the chicken stock. Simmer, stirring occasionally for 5-10 minutes or until reduced by half.
Notes
Olive Oil: Use a high-quality extra virgin olive oil, if possible. I recommend Spanish olive oil from Trader Joe’s or Costco (or Whole Foods, but its pricier).
White Wine: Use a dry white wine for this sauce. I often use a dry Portuguese white wine, but choose your favorite; something that you would enjoy drinking.
Butter: Use salted butter.
Lemon Zest: Zest only the outermost bright yellow portion of the lemon, not the inner white pith.
