Preparation Phase & Tools to Use

Before diving into the world of creamy garlic bliss, it helps to have your tools lined up and ready:

• Large Nonstick Skillet or Saucepan: This is the heart of the recipe. A wide, deep skillet ensures even heat distribution so the garlic sautés evenly and the cheese melts into a smooth sauce.
• Wooden Spoon or Silicone Spatula: For stirring the sauce gently and scraping the sides without scratching your pan.
• Microplane or Fine Grater: Freshly grated Parmesan melts more smoothly and adds a better texture.
• Measuring Cups and Spoons: Precision ensures a perfect balance of flavors, especially when working with strong ingredients like garlic and cheese.
• Whisk: Crucial for combining the broth, cream, and cheese without clumping.

With everything set, you’re just minutes away from creamy garlic perfection.

Ingredients for the One Pot Garlic Parmesan Sauce

• Butter – Adds richness and depth to the base of the sauce. It also helps cook the garlic gently without burning.
• Fresh Garlic – The star of the show. It infuses the sauce with bold, aromatic flavor. Freshly minced is best.
• All-Purpose Flour – Used to thicken the sauce and give it that creamy, luscious texture.
• Chicken Broth – Adds savory complexity and balances out the richness.
• Heavy Cream – Delivers the velvety, indulgent texture this sauce is known for.
• Parmesan Cheese – The key flavor booster. Salty, nutty, and melty, it makes the sauce sing.
• Salt and Black Pepper – Essential for seasoning and enhancing every bite.
• Italian Seasoning – Brings warmth and an herbal note that complements the garlic beautifully.
• Crushed Red Pepper Flakes (optional) – For a little kick, if you like a bit of heat.

How To Make the One Pot Garlic Parmesan Sauce

Step 1: Build the Flavor Base

In a large nonstick skillet, melt butter over medium heat. Once melted, add the minced garlic and sauté until fragrant—about 1 to 2 minutes. Be careful not to brown the garlic, as it can turn bitter.

Step 2: Create the Roux

Sprinkle the flour evenly into the skillet and whisk continuously. This forms a roux that thickens the sauce and prevents lumps. Cook for another minute until golden.

Step 3: Add Liquid Ingredients

Slowly pour in the chicken broth while whisking. Then add the heavy cream. Stir until the mixture is smooth and starts to thicken.

Step 4: Stir in the Cheese and Seasonings

Lower the heat and gradually add the grated Parmesan cheese. Stir constantly to melt the cheese completely. Add Italian seasoning, salt, pepper, and red pepper flakes if using.

Step 5: Simmer and Serve

Let the sauce simmer for 2–3 minutes to thicken to your desired consistency. If it’s too thick, add a splash of broth. Serve immediately over pasta, chicken, or vegetables.

How to Serve and Store One Pot Garlic Parmesan Sauce

This sauce is incredibly versatile. Spoon it generously over al dente pasta like fettuccine, penne, or rotini. It’s also a perfect topping for baked chicken, shrimp, or even steamed broccoli.

For storing, let the sauce cool completely before transferring it to an airtight container. It keeps well in the fridge for up to 4 days. Reheat gently on the stove with a splash of broth or cream to restore its creamy texture.

You can also freeze the sauce, but keep in mind that the texture may change slightly upon thawing. Whisking during reheating helps bring it back together.
