Ingredients
- 2 Tbsp. butter
- 4 garlic cloves, grated with a microplane
- 2 Tbsp. all-purpose flour
- 2 cups half and half (not fat free)
- Zest of 1 lemon (about 1 tsp.)
- 2 Tbsp. fresh lemon juice
- 1/3 cup grated Parmesan cheese
- 1 Tbsp. finely chopped parsley

Instructions
- Step 1: In a 12-inch non-stick skillet, melt the butter over medium heat. Add the grated garlic and cook for about 30 seconds, stirring constantly, until fragrant.
- Step 2: Stir in the flour and cook for 1 minute, stirring constantly to avoid burning and to cook off the raw flour taste.

Tips & Variations
- For a richer sauce, substitute half of the half and half with heavy cream.
- Add a pinch of red pepper flakes for a subtle spicy kick.
- Use fresh garlic instead of grated for more texture if preferred.
- Try stirring in cooked shrimp or grilled chicken to turn this sauce into a complete meal.
- If the sauce gets too thick, thin it with a splash of pasta cooking water.
Storage
Store leftover sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat, stirring frequently to prevent separation. Add a little water or milk if the sauce becomes too thick when reheating.

FAQs
Can I use milk instead of half and half?
You can use whole milk, but the sauce will be less creamy and rich. To compensate, consider adding a bit of butter or cream to enhance the texture.
How to prevent lumps in the sauce?
Whisk continuously as you gradually add the half and half to the flour and butter mixture. If lumps form, use a whisk or an immersion blender to smooth the sauce out before it thickens fully.

Ingredients
Sauce Ingredients
- 2 Tbsp. butter
- 4 garlic cloves, grated with a microplane
- 2 Tbsp. all-purpose flour
- 2 cups half and half (not fat free)
- Zest of 1 lemon (about 1 tsp.)
- 2 Tbsp. fresh lemon juice
- 1/3 cup grated Parmesan cheese
- 1 Tbsp. finely chopped parsley
- Kosher salt, to taste
- Fresh black pepper, to taste
Instructions
- Prepare the garlic butter base: In a 12-inch non-stick skillet, melt the butter over medium heat. Add the grated garlic cloves and cook for 30 seconds, stirring constantly until fragrant but not browned.
- Make the roux: Stir in the all-purpose flour and continue stirring constantly for about 1 minute until the mixture turns lightly golden. This cooks off the raw flour flavor without burning it.
- Add half and half: Gradually whisk in the half and half while stirring to prevent lumps. Season with kosher salt and fresh black pepper to taste. Reduce the heat to medium-low and simmer for 1 to 2 minutes until the sauce thickens and coats the back of a spoon. Whisk out any lumps that may form.
- Finish with lemon and cheese: Whisk in the lemon juice and zest to impart fresh citrus flavor. Stir in the grated Parmesan cheese and chopped parsley until the cheese has melted completely and the sauce is smooth.
- Serve immediately: Use the sauce right away by tossing it with cooked pasta of your choice for a bright, creamy dish.
Notes
- Use freshly grated garlic with a microplane for the best flavor and smooth texture.
- Do not rush cooking the flour to avoid a raw taste, but be careful not to burn the roux.
- If lumps form when adding the half and half, use a whisk to smooth out the sauce.
- For a thicker sauce, cook a bit longer over low heat until desired consistency is reached.
- Serve immediately to enjoy the fresh lemon flavors; reheating may reduce brightness.
- Pairs exceptionally well with fettuccine, linguine, or any long pasta.
