Full Ingredients

Roasted Garlic

• 1 large head garlic
• 1 1/2 tsp olive oil

Garlic–Parmesan Cream Sauce

• 1 cup heavy cream
• 2 tbsp unsalted butter
• 3/4 cup finely grated Parmesan cheese (about 2 1/2 oz), plus more for serving
• 1/2 tsp kosher salt, plus more to taste
• 1/2 tsp freshly cracked black pepper, plus more to taste
• 1 tsp fresh lemon juice (optional, for a lighter finish)

Optional for Serving

• Cooked pasta (8–12 oz dry pasta)
• Steamed or roasted broccoli
• Grilled or pan-seared chicken
• Chopped parsley (1 tbsp) for a fresh finish

Step-by-Step Instructions

Step 1: Heat the oven and prep the garlic

Preheat your oven to 375°F (190°C). Peel away any loose, papery outer layers from 1 large head of garlic, keeping the head intact. Using a sharp knife, slice off about 1/2 inch from the top to expose the tops of the cloves.

Place the garlic on a square of foil, drizzle with 1 1/2 tsp olive oil, and wrap it up tightly into a packet with the cut side facing up (so the oil can seep into the cloves).

Step 2: Roast until sweet, soft, and golden

Set the foil packet on a baking sheet (for easy handling) and roast for 50–60 minutes, until the cloves are deeply softened and lightly golden. If you can easily squeeze a clove and it feels like soft butter inside, it’s ready.

Carefully open the foil (watch for steam) and let the garlic cool for 5 minutes so it’s comfortable to handle.

Step 3: Blend the roasted garlic with the cream until perfectly smooth

Squeeze the roasted garlic cloves out of their skins into a blender (or a small food processor). Add 1 cup heavy cream.

Blend for 20–30 seconds, scraping down the blender if needed, until the mixture looks completely smooth and uniform. This blending step is the key to a truly silky sauce (no garlic bits).

Step 4: Warm the sauce base gently

In a small saucepan over medium-low heat, melt 2 tbsp unsalted butter. Pour in the blended garlic-cream mixture.

Bring it to a gentle simmer (avoid a hard boil) and cook for 3–5 minutes, whisking often, until it’s hot and slightly thickened. You’re not trying to reduce it dramatically; you’re just melding flavors and building a silky body.

Step 5: Whisk in Parmesan for a smooth, glossy finish

Turn the heat down to low. Add the 3/4 cup finely grated Parmesan a small handful at a time, whisking well between additions. Keep whisking until the cheese fully melts into the sauce and it looks glossy and smooth.

If the sauce seems too thick, whisk in 1–2 tbsp warm water (or hot pasta water if you’re using it for pasta) until it reaches your preferred “drizzle” consistency.

Step 6: Season with salt, cracked pepper, and optional lemon juice

Remove from the heat. Stir in 1/2 tsp kosher salt and 1/2 tsp freshly cracked black pepper. Taste and adjust: add more salt or pepper if you want it punchier.

For a slightly lighter, brighter finish, stir in 1 tsp fresh lemon juice (optional). This helps balance the richness, especially if you’re drizzling it over broccoli or chicken.

Step 7: Serve right away (or keep warm gently)

Use the sauce immediately while it’s silky and fluid. Drizzle over steamed broccoli, spoon over grilled chicken, or toss with hot pasta (thin with a splash of pasta water for a clingy, glossy coating). Finish with extra Parmesan and another crack of black pepper.

Pro Tips

• Grate your own Parmesan: Finely grated Parmesan melts much more smoothly than shredded. Avoid shelf-stable “powdery” Parmesan for the silkiest texture.
• Keep the heat low once the cheese goes in: High heat can make cheese turn grainy or separate.
• Adjust thickness on purpose: For pasta, keep it slightly looser and use pasta water. For chicken, simmer 1–2 minutes longer for a thicker spoonable sauce.
• Want extra peppery bite? Add an additional 1/4 tsp cracked black pepper at the end so it stays aromatic.
• No blender? Mash roasted garlic into a smooth paste with a fork, then whisk vigorously into the cream. It won’t be quite as silky, but it will still be delicious.

Variations

• Herby garlic-Parmesan sauce: Stir in 1 tsp chopped fresh thyme or 1 tbsp chopped parsley right before serving.
• Spicy roasted garlic cream: Add 1/8–1/4 tsp crushed red pepper flakes while warming the sauce base.
• Lemon-pepper version: Use the optional lemon juice and add 1/2 tsp finely grated lemon zest off heat for a brighter, more aromatic drizzle.

Storage & Make-Ahead

Cool the sauce, then store in an airtight container in the refrigerator for up to 4 days. Reheat gently in a saucepan over low heat, whisking often. If it thickens in the fridge (it will), thin it with 1–3 tbsp warm water, milk, or cream until silky again. Avoid boiling during reheating to prevent separation.

You can roast the garlic up to 3 days ahead and keep the squeezed cloves refrigerated; then make the sauce fresh in about 10 minutes.
