Warming Roasted Garlic Miso Soup

Cold weather always makes me crave a warm bowl of soup. There’s something about slurping something hot and comforting that just hits the spot when it’s chilly outside. But I don’t always want the same old chicken noodle or tomato soup that I grew up with.

That’s where this roasted garlic miso soup comes in. The roasted garlic adds this deep, sweet flavor that’s nothing like raw garlic. And the miso? It brings this rich, salty taste that makes the whole bowl feel more satisfying. I like to make a big batch on Sunday and reheat it throughout the week for quick lunches.

Want something creamy but not heavy? This soup has you covered. Need dinner ready in about 30 minutes? Same. Honestly, this has become my go-to recipe when I want something that feels fancy but doesn’t require a ton of work.

What Kind of Miso Should I Use?

For this roasted garlic miso soup, white miso (also called shiro miso) is your best bet since it has a mild, slightly sweet flavor that won’t overpower the roasted garlic. You can find white miso in the refrigerated section of most grocery stores, usually near the tofu or in the international aisle. If you can only find red or dark miso, you can still use it, but start with less since these varieties have a much stronger, saltier taste. Keep in mind that miso is a fermented paste, so it should be stored in the fridge and will last for months once opened.

Options for Substitutions

This simple soup is quite forgiving when it comes to swaps and substitutions:

• White miso: This is the star of the show, so I wouldn’t skip it entirely. But if you only have red miso, use about half the amount since it’s much saltier and stronger in flavor.
• Kale: Not a kale fan? Try spinach, chard, or bok choy instead. Spinach will wilt much faster, so add it in the last minute of cooking.
• Vegetable broth: Water works fine if that’s all you have, but the soup will be less flavorful. You can also use chicken broth if you’re not keeping it vegetarian.
• Roasted garlic: If you’re short on time, you can use 3-4 cloves of fresh minced garlic sautéed in the olive oil, but you’ll miss out on that sweet, mellow roasted flavor.
• Olive oil: Any neutral oil like avocado or vegetable oil will work for roasting the garlic.
• Green onions: Regular chives, sliced regular onions, or even a sprinkle of sesame seeds make nice garnish alternatives.

Watch Out for These Mistakes While Cooking

The biggest mistake when roasting garlic is cranking up the heat too high, which will burn the outside while leaving the inside raw – keep your oven at 400°F and wrap the garlic heads in foil with olive oil for even cooking.

Never add miso paste directly to boiling water, as the high heat will destroy its beneficial probiotics and create a grainy texture instead of the smooth, creamy consistency you want.

To get the perfect balance, whisk your miso with a small amount of warm broth in a separate bowl first, then gradually stir this mixture back into the pot off the heat.

Adding the kale at the right time is crucial too – toss it in during the last 2-3 minutes of cooking so it wilts perfectly without becoming mushy, and always taste before adding salt since miso is already quite salty.

What to Serve With Roasted Garlic Miso Soup?

This savory soup pairs beautifully with some crusty bread or warm dinner rolls for dipping, especially since the roasted garlic flavors are so rich and comforting. I love serving it alongside a simple rice bowl or some steamed jasmine rice to make it more filling, and the miso broth soaks into the rice perfectly. For a lighter option, try it with some crispy sesame crackers or a fresh cucumber salad with rice vinegar dressing to balance out the umami flavors. You can also make it a complete meal by adding some cooked noodles like udon or ramen directly into the soup, along with maybe some soft-boiled eggs or tofu for extra protein.

Storage Instructions

Refrigerate: This miso soup keeps really well in the fridge for up to 4 days in an airtight container. The flavors actually get better as they sit together, so it’s perfect for meal prep. Just keep in mind that the kale might soften a bit more, but it still tastes great.

Freeze: You can freeze this soup for up to 3 months, though I’d recommend adding fresh kale when you reheat it since frozen kale can get a bit mushy. Pour the cooled soup into freezer-safe containers, leaving some room at the top for expansion.

Warm Up: Gently reheat the soup on the stovetop over medium-low heat, stirring occasionally until it’s heated through. If you’re warming it from frozen, let it thaw overnight in the fridge first. Add a fresh squeeze of lemon and green onions right before serving to brighten it up again.

Ingredients

For the roasted garlic:

• 2 whole garlic bulbs
• 2 tbsp olive oil

For the miso soup:

• 6 cups water or vegetable broth
• 3 to 4 tbsp white miso paste
• 4 cups chopped kale
• Himalayan salt, as needed

For serving:

• Red pepper flakes, pinch for garnish
• Lemon wedge or juice, optional
• Sliced green onions, optional

Step 1: Roast the Garlic

• 2 whole garlic bulbs
• 2 tbsp olive oil

Preheat your oven to 400°F (200°C).

Remove most of the outer layers of skin from the garlic bulbs, leaving the innermost layer to keep them together.

Slice the tops off the garlic bulbs to expose the cloves.

Place them cut side up on a sheet of tin foil, then drizzle 1 tablespoon olive oil over each bulb.

Fold and seal the foil around the bulbs, pinching or folding the ends to close tightly.

Roast the wrapped bulbs in the oven for 45–50 minutes, then let them cool for 10 minutes before handling.

Step 2: Make the Broth and Incorporate the Roasted Garlic

• roasted garlic (from Step 1)
• 6 cups water or vegetable broth
• 3 to 4 tbsp white miso paste
• himalayan salt, as needed

Once the garlic bulbs have cooled, squeeze the roasted cloves out into a large pot.

Use the back of a wooden spoon to mash the garlic cloves slightly, creating a flavorful base.

Pour in the water or vegetable broth and bring the mixture to a gentle simmer over medium-low heat.

Stir in the miso paste until it is fully dissolved into the broth.

I like to taste the broth at this point and adjust the level of miso to my preference, adding a pinch of Himalayan salt if needed.

Step 3: Add the Kale and Finish the Soup

• 4 cups chopped kale

Add the chopped kale to the broth and allow it to wilt, cooking until the leaves are soft and deep dark green, about 5–10 minutes.

Stir occasionally to help the kale cook evenly.

Step 4: Serve and Garnish the Soup

• red pepper flakes, pinch for garnish
• lemon wedge or juice, optional
• sliced green onions, optional

Ladle the hot soup into bowls.

Garnish each serving with a pinch of red pepper flakes, a squeeze of lemon juice or a lemon wedge, and some sliced green onions if desired.

I love adding extra lemon at the end for a little extra brightness!
