Lemon parsley sauce is a vibrant, versatile condiment that pairs the bright acidity of fresh lemon with the clean, peppery notes of flat-leaf parsley. It comes together in minutes and works as a quick pan sauce, a dressing for roasted vegetables, or a finishing touch for fish and chicken. The combination of lemon, parsley, and a rich base like butter or cream creates a balanced sauce that is both light and satisfying.
Ingredients
- 1 cup (240 ml) low-sodium chicken or vegetable broth
- 1/2 cup (120 ml) dry white wine (optional; see Tips)
- 1 shallot, finely chopped (about 2 tablespoons / 20 g)
- 2 cloves garlic, minced
- 1 cup (240 ml) heavy cream (or half-and-half for a lighter sauce)
- 1 lemon: zest (about 1 teaspoon) and juice (about 2 tablespoons / 30 ml)
- 1/2 cup (20 g) fresh flat-leaf parsley, finely chopped
- 2 tablespoons (28 g) unsalted butter
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper, plus more to taste
Instructions
- In a medium saucepan or skillet, melt the butter over medium heat. Add the shallot and cook, stirring occasionally, until softened and translucent, about 2-3 minutes. Add the garlic and cook for another 30 seconds until fragrant.
- If using wine, pour it in and let it bubble, scraping up any browned bits from the bottom of the pan. Cook until the wine has reduced by half, about 2 minutes. If not using wine, skip this step and proceed.
- Add the chicken or vegetable broth and bring to a simmer. Let it cook, stirring occasionally, until the liquid has reduced by about half, about 4-5 minutes.
- Reduce the heat to low and stir in the heavy cream. Let the sauce warm through gently, about 2 minutes, but do not let it boil.
- Remove the pan from the heat. Stir in the lemon zest, lemon juice, and chopped parsley. Season with salt and pepper to taste. The sauce should be bright and well-seasoned.
- Serve immediately over your chosen dish, or keep warm over very low heat, stirring occasionally, for up to 15 minutes.
Tips
- Substitutions: If you don’t have white wine, use an extra 1/2 cup (120 ml) of broth. For a dairy-free version, replace the heavy cream with full-fat coconut milk and use olive oil instead of butter; the flavor will change but will still be delicious.
- Don’t boil the cream: After adding the cream, keep the heat low. Boiling can cause the cream to curdle and separate, ruining the sauce’s smooth texture.
- Use fresh lemon: Bottled lemon juice lacks the bright, aromatic quality of fresh lemon. Always use a fresh lemon for the best flavor.
- Chop parsley finely: Finely chopped parsley distributes more evenly and releases more flavor into the sauce. Avoid using the tough stems; use only the leaves.
Serving Suggestions
This sauce is incredibly versatile. It’s perfect over pan-seared or baked fish, such as cod, halibut, or salmon. It also works beautifully with chicken breast, pork chops, or roasted vegetables like asparagus, green beans, or potatoes. For a light pasta dish, toss it with cooked linguine or fettuccine and a handful of peas.
Variations
- Caper-Lemon Parsley Sauce: Add 2 tablespoons of drained capers along with the parsley for a briny, tangy twist.
- Garlic-Herb Sauce: Increase the garlic to 3 cloves and add 1 teaspoon of fresh thyme leaves along with the parsley.
- Spicy Lemon Parsley Sauce: Add a pinch of red pepper flakes or a small chopped chili with the garlic for a hint of heat.
- Mustard-Lemon Sauce: Whisk in 1 tablespoon of Dijon mustard with the cream for extra depth and a slight tang.
Storage and Reheating
Store leftover sauce in an airtight container in the refrigerator for up to 3 days. To reheat, place it in a small saucepan over low heat, stirring frequently, until warmed through. You may need to add a splash of broth or water to loosen the sauce, as it will thicken when chilled. Avoid boiling, as this can cause the cream to separate. The sauce is not suitable for freezing, as the cream will likely separate upon thawing.
Frequently Asked Questions
Can I use dried parsley instead of fresh? Dried parsley has a much milder flavor and a different texture. For this sauce, fresh parsley is strongly recommended. If you must substitute, use 1/4 cup (5 g) of dried parsley, but the sauce will be less vibrant.
What can I use instead of heavy cream? Half-and-half or whole milk will work, but the sauce will be thinner and less rich. For a dairy-free alternative, full-fat coconut milk is a good option, though it will add a slight coconut flavor.
How do I keep the sauce from curdling? The key is to avoid high heat after adding the cream. Always keep the sauce at a gentle simmer or lower, and never let it boil. Also, add the lemon juice at the end, off the heat, as acid can also cause curdling if added too early.
Can I make this sauce ahead of time? Yes, you can make it up to a day in advance. Reheat gently over low heat, adding a little broth or water to thin it if needed. For best flavor, add the fresh parsley just before serving.
What if I don’t have white wine? Simply omit it and increase the broth by 1/2 cup (120 ml). The sauce will still be delicious, just slightly less complex. You can also use a splash of dry vermouth or even a little extra lemon juice.
Is this sauce suitable for freezing? No, freezing will cause the cream to separate and the texture to become grainy. It’s best to make only what you need and store leftovers in the fridge.
