The Method for Roasted Garlic Horseradish Sauce

Get ready to indulge in the deliciousness of Roasted Garlic Horseradish Sauce! Follow these simple steps for a sauce that’s bursting with flavor.
Step 1: Roast the Garlic
Preheat your oven to 400°F (200°C). Cut off the top of the garlic head to expose the cloves. Drizzle with 1 teaspoon of olive oil and sprinkle with a pinch of kosher salt. Wrap the garlic head in aluminum foil and place it in the oven. Roast for about 30-35 minutes, or until the cloves are soft and caramelized.
Step 2: Prepare the Sauce Base
While the garlic is roasting, add 1-1/2 cups of sour cream to a mixing bowl. To this, add the prepared horseradish, Worcestershire sauce, thyme, and the remaining 1 teaspoon of olive oil. Season with ½ teaspoon of kosher salt and freshly-ground black pepper.
Step 3: Add the Roasted Garlic
Once the garlic is done roasting, allow it to cool for a few minutes. Carefully squeeze the roasted garlic cloves out of their skins and into the mixing bowl with the other ingredients. Use a fork or a garlic press to mash the garlic into the mixture.
Step 4: Mix Until Smooth
Using a whisk or a spoon, mix all the ingredients together until well combined and smooth. Taste the sauce and adjust seasoning if necessary.
Step 5: Chill and Serve
Cover the bowl with plastic wrap or transfer the sauce to an airtight container. Refrigerate for at least 30 minutes to allow the flavors to meld. Serve chilled or at room temperature with your favorite dishes!
Quick Replacement Ideas

If you find yourself missing an ingredient, don’t worry! Here are some quick replacements you can use:
- Sour cream: Greek yogurt can be a great substitute for a tangy flavor.
- Horseradish: If you can’t find prepared horseradish, you can use wasabi as an alternative, but use it sparingly.
- Worcestershire sauce: Soy sauce mixed with a splash of vinegar can mimic the umami flavor.
- Thyme: Dried thyme can be used in a pinch; just use about 1/3 the amount.
What Not to Do
When making your Roasted Garlic Horseradish Sauce, keep these tips in mind to ensure the best results:
- Do not rush the roasting process; undercooked garlic will yield a bitter flavor.
- Avoid using pre-minced garlic; fresh roasted garlic is key to achieving the desired depth of flavor.
- Don’t skip the chilling time; this allows the flavors to develop fully.
- Be cautious with the horseradish; start with less and add more to taste if you prefer a spicier sauce.
