How to Make Roasted Garlic & Creamy Potato Soup
-
Preheat the oven to 375ºF. This step ensures that the garlic roasts evenly and develops that delectable, sweet flavor we love.
-
Prepare the garlic by slicing off the top layer of the heads to expose the cloves. Peel off excess outer layers for better roasting.
-
Drizzle the exposed cloves with olive oil and sprinkle with salt and coarse pepper. Wrap the garlic in aluminum foil and place it on a baking sheet.
-
Roast in the oven for about 40 minutes, until the cloves are fragrant and take on a lovely golden color. Your kitchen will smell divine!
-
Squeeze the roasted garlic out of the skins and set aside. This soft, sweet garlic is the star of your soup!
-
Melt butter in a large pot or Dutch oven over low-medium heat. Add the chopped onions and sauté them for about 5 minutes until they become translucent.
-
Sprinkle the sautéed onions with flour, mixing well. Stir until combined without browning the flour, which keeps your soup smooth.
-
Pour in the broth (starting with 4 cups), milk, half-and-half, thyme, salt, and pepper. Whisk everything together to create a creamy base.
-
Bring the soup to a boil, then reduce the heat to the lowest setting. Let it simmer for a couple of minutes to meld those beautiful flavors.

Add the cooked potatoes and the roasted garlic to the pot. Stir to incorporate these hearty ingredients into the mix.

Blend the soup in batches until completely smooth, adding more broth as needed for your desired consistency. It should be silky and luscious!

Expert Tips for Roasted Garlic & Creamy Potato Soup
• Choose Fresh Garlic: Ensure your garlic heads are firm and have no soft spots for the best flavor. Fresh ingredients make a significant difference in your Roasted Garlic & Creamy Potato Soup.

• Customize Toppings: Feel free to get creative with your toppings! Fresh herbs, different types of cheese, or crispy bacon bits can elevate your soup and make it uniquely yours.
• Thickening Tip: Uncertain about how thick you want your soup? Start with the minimum broth amount; you can always add more during blending to achieve your desired consistency.
