Sure, here is a simple recipe for a Rosemary Garlic Sauce that you could use:
**Ingredients:**
- 5 cloves of garlic, minced
- 2 tablespoons fresh rosemary, finely chopped
- 1 cup of chicken broth
- 1/2 cup of heavy cream
- 2 tablespoons of butter
- 1 tablespoon of olive oil
- Salt and pepper to taste
- Optional: a squeeze of fresh lemon juice
**Instructions:**
1. Heat the olive oil in a saucepan over medium heat.
2. Add the minced garlic and chopped rosemary. Sauté for about 1-2 minutes, or until fragrant. Be careful not to burn the garlic.
3. Pour in the chicken broth. Bring the mixture to a simmer and let it reduce by half. This should take around 5-7 minutes.
4. Lower the heat and add the heavy cream, stirring to combine. Allow the sauce to simmer for a few more minutes until it thickens slightly.
5. Stir in the butter, allowing it to melt into the sauce. This will give your sauce a rich, glossy finish.
6. Season with salt and pepper to taste. If using, add a squeeze of lemon juice to brighten the flavors.
7. Serve warm with your BBQ rack of lamb.
Remember to adjust the seasonings according to your preferences. Enjoy your meal!
