Roasted Garlic and Buttermilk Salad Dressing: A Symphony of Flavor

There’s a particular kind of magic that happens when humble garlic is coaxed into sweetness through the gentle heat of the oven. I remember, years ago, a summer picnic where a vibrant green salad was the star, not because of exotic greens or a complex assembly, but because of the dressing. It was creamy, tangy, with a deep, mellow garlic undertone that was utterly captivating. That dressing, I later learned, was born from the simple brilliance of roasted garlic and the cooling embrace of buttermilk. It’s a revelation for anyone who’s only ever encountered raw, sharp garlic in their dressings, and it’s become a staple in my own kitchen, a testament to how transformative a little patience and heat can be.

Instructions

The journey to this exquisite dressing begins with transforming raw garlic into something wonderfully mellow and sweet. This is achieved through roasting, a process that requires your oven and a touch of patience.

1. Preheat your oven to 400°F (200°C). This moderate temperature is perfect for slowly softening the garlic cloves without burning them.
2. Prepare the garlic heads. For each head of garlic, carefully cut off the top half-inch, exposing the individual cloves within. You want to reveal the tops of the cloves without detaching them from the root.
3. Wrap the garlic. Place each prepared head of garlic on a separate square of aluminum foil.
4. Drizzle with oil. Drizzle about 1 tablespoon of olive oil over each head of garlic. This helps to facilitate the roasting and adds a subtle richness.
5. Enclose in foil. Enclose each head of garlic tightly in its foil packet. This traps the steam and moisture, ensuring the garlic roasts evenly and becomes incredibly tender.
6. Bake the garlic. Place the foil-wrapped garlic directly on an oven rack. Bake until the garlic is tender, which should take approximately 45 minutes. The garlic should feel very soft when squeezed through the foil.
7. Cool the garlic slightly. Once baked, carefully remove the garlic packets from the oven. Open the foil cautiously, as steam will escape, and allow the garlic to cool for a few minutes until it’s safe to handle.
8. Squeeze out the roasted pulp. Hold one head of the slightly cooled garlic, cut-side down, directly over a medium bowl. Gently squeeze the head, releasing the soft, roasted garlic pulp into the bowl.
9. Repeat with remaining garlic. Repeat this process with the remaining roasted garlic head, squeezing all the softened pulp into the same bowl. You should have a beautiful, golden paste.
10. Mash the garlic. Mash the collected roasted garlic pulp with a fork or the back of a spoon until it forms a smooth paste. Ensure there are no large chunks.
11. Incorporate the remaining ingredients. To the bowl with the mashed garlic, whisk in the mayonnaise, buttermilk, freshly grated Parmesan cheese, fresh lemon juice, and Worcestershire sauce. Continue whisking until all ingredients are thoroughly combined and the dressing is smooth and homogenous.
12. Season to taste. Season the dressing generously with salt and pepper. Taste and adjust the seasonings as needed. The salt will balance the richness, and the pepper will add a subtle warmth.
13. Chill the dressing. Cover the bowl tightly and chill the dressing in the refrigerator until you are ready to use it. For the best flavor, allow it to meld for at least 30 minutes. The dressing can be made up to 2 days in advance and will continue to deepen in flavor as it chills.

Expert Tips & Tricks

• Garlic Selection: Choose firm, plump heads of garlic with no soft spots or green shoots. These will yield the best flavor and texture when roasted.
• Preventing Burning: While 400°F is the target, ovens can vary. Keep an eye on your garlic during the last 10-15 minutes of roasting. If the foil starts to brown excessively, you can loosely tent it.
• Smoothness is Key: For an ultra-smooth dressing, you can transfer the mashed roasted garlic and the other ingredients to a blender or food processor and pulse until completely emulsified.
• Buttermilk Substitute: If you don’t have buttermilk on hand, you can create a quick substitute by adding 1 tablespoon of white vinegar or lemon juice to 1 cup of milk and letting it sit for 5-10 minutes.
• Parmesan Quality: Using high-quality, freshly grated Parmesan cheese will make a noticeable difference in the final flavor profile. Pre-grated cheeses often contain anti-caking agents that can affect the texture.

Serving & Storage Suggestions

This Roasted Garlic and Buttermilk Salad Dressing is incredibly versatile. It’s absolutely divine poured over wedges of crisp iceberg lettuce or quartered heads of romaine for a classic wedge salad. It also elevates simple mixed greens, potato salads, or can even be used as a dip for crudités.

Storage:

• Refrigeration: Store the dressing in an airtight container in the refrigerator. It will keep well for up to 5 days.
• Room Temperature: This dressing should not be left at room temperature for extended periods due to the mayonnaise and buttermilk content.
• Freezing: It is not recommended to freeze this dressing, as the mayonnaise can separate and the texture may be compromised upon thawing.
