Recipe ingredients & notes:
- For a garden-fresh herb flavor you can use finely chopped fresh oregano instead of the dried herb. (And if you have fresh oregano left, use it to make this spicy burger sauce recipe or this broccoli soup recipe!)
- You can use pre-grated Parmesan or freshly grated Parmesan cheese for this recipe. Both work great!
- You need the zest of one small lemon for this recipe. Suggestion: Juice the lemon after zesting and use the juice to make this flavorful kale lemon pasta or this scallion aioli recipe!

How to make it:

Step 1. This sauce is very simple to make. Start by melting butter in a saucepan or skillet.

Step 2. Add garlic and cook until fragrant.

Step 3. Add chicken broth, heavy cream and Parmesan. Bring to a boil and cook, stirring continuously, until the sauce thickens.

Step 4. Stir in oregano and lemon zest.

How to serve it:
This sauce is great on grilled, baked, fried or roasted chicken or seafood. It also makes a great ravioli sauce.
Here are a few options of how to use it:
- If you're in a time crunch, cut a chicken breast into bite-sized cubes, toss them with vegetable oil and put under the broiler until the chicken is cooked (~10 min.), then serve with this sauce and rice for a delicious meal in minutes.
- Alternatively, you can pound a chicken breast really thin (about ¼ inch thick*), then coat it with all-purpose flour on both sides. Fry the chicken breast in melted butter in a cast iron pan until cooked (about 5 minutes on each side).
*RECIPE NOTE: The meat has to be that thin to cook quickly. If you leave it thicker than that, it will take quite a bit longer to cook through.
Recipe notes, tips and questions:
When to add oregano to the sauce?
Add oregano (whether you're using dried or fresh herb) at the end of the cooking process.
How to store leftover sauce:

I absolutely love the touch of lemon in this. I made it to put on grilled chicken and rice, and it was wonderful! Now I'm going to have to try it on fish!

So happy to hear you liked the sauce, Steffani! I love cooking with citrus zest, it adds so much flavor without the intense acidity.
