Let’s get started!

What You’ll Need
Ingredients:
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 ½ cups heavy cream (or half-and-half for a lighter version)
- 1 ¼ cups freshly grated Parmesan cheese
- ½ teaspoon salt (adjust to taste)
- ½ teaspoon black pepper
- ½ teaspoon Italian seasoning (optional)
- ¼ teaspoon red pepper flakes (optional, for a mild kick)
- ½ cup reserved pasta water (to adjust sauce consistency, if needed)
- 2 tablespoons chopped fresh parsley (for garnish)
Tools:
- Saucepan or skillet
- Whisk
- Measuring cups and spoons
Pro Tips
- Use freshly grated Parmesan instead of pre-shredded cheese for the smoothest sauce.
- Keep the heat medium-low when adding Parmesan to prevent clumping.
- For an extra silky texture, whisk continuously while combining the ingredients.
- If the sauce thickens too much, stir in a little reserved pasta water to loosen it.
Substitutions and Variations
- Lighter Version: Use half-and-half instead of heavy cream.
- Dairy-Free: Substitute coconut cream and nutritional yeast for a dairy-free alternative.
- Extra Rich Flavor: Add a splash of white wine before adding the cream.
- Garlic Parmesan Twist: Increase the garlic for a bolder flavor.
- Protein Additions: Serve with grilled chicken, shrimp, or crispy bacon.
How to Make It
1. Melt Butter and Sauté Garlic
In a large saucepan over medium heat, melt the butter. Add minced garlic and sauté for 30 seconds until fragrant.

2. Add Cream and Simmer
Pour in the heavy cream and whisk well. Let it simmer gently for 2–3 minutes, allowing the flavors to meld.

3. Stir in Parmesan and Seasoning
Reduce the heat to medium-low and gradually stir in the Parmesan cheese, salt, black pepper, and Italian seasoning. Keep whisking until the sauce is smooth and velvety.

4. Adjust Consistency
If the sauce is too thick, stir in small amounts of reserved pasta water until it reaches your desired consistency.

5. Serve and Garnish
Toss the sauce with cooked pasta, then sprinkle with fresh parsley. Serve immediately for the best flavor.

Leftovers and Storage
- Refrigerate: Store in an airtight container for up to 3 days.
- Reheat: Warm over low heat, adding a splash of milk or cream to bring back the creamy texture.
- Do Not Freeze: Cream-based sauces can separate when frozen and thawed.
