Why I Love This Recipe

As someone that grew up with Japanese cuisine, I’m thrilled to introduce my Japanese Style Roasted Garlic Bulb! Similar to my Japanese Soy Sauce Pickled Garlic, this recipe offers a traditional yet innovative way to savor garlic, but this time, it’s oven-roasted and seasoned with authentic Japanese flavors! What makes my dish truly special is my oven roasting approach, inspired by my Roasted Shiitake Mushroom and Crispy Baked Garlic Kale Chips recipes!

With minimal prep and my proven oven roasting method, you’ll enjoy savory-sweet roasted garlic bursting with flavor. It’s the perfect side dish to accompany grilled protein or a Japanese-inspired meal, offering both delicious taste and health benefits!

Step 2 Start by preparing the head of garlic. Use a knife to cut off approximately 1 inch from the top of the garlic head, exposing the cloves at the top. Then, wrap the whole head of garlic in aluminum foil. Drizzle the sauce on top of the garlic, ensuring it’s evenly distributed, and let the sauce marinate for 10-15 minutes.

💡 Marinating Pro Tip

For enhanced flavor, allow the garlic to Marinate for 30-45 Minutes. This extended marinating time allows the flavors to fully infuse into the garlic, resulting in a richer and more pronounced taste.

Step 3 Next place garlic in the oven and roast at 400F for 25-30 minutes.

Frequently Asked Questions

Can I use pre-peeled garlic cloves instead of a whole bulb?

No, for this recipe, it's essential to use a whole garlic bulb rather than pre-peeled cloves. The outer bulb is needed to roast and marinate the cloves, ensuring the desired flavor and texture.

Should I remove the outer skin of the garlic bulb before roasting?

No, it's not necessary to remove the outer skin of the garlic bulb before roasting. Simply cut the top to expose the cloves, but leave the outer skin intact. This helps to retain the marinade during the roasting process.

How do I know when the garlic bulb is done roasting?

When the garlic bulb is done roasting, you'll notice a brown tint on the cloves, indicating they're fully cooked. Additionally, the cloves should be easy to pull out from the bulb, and when pierced, they should have a tender texture.

Storage Tips

Store the leftover roasted garlic in an airtight container in the refrigerator for 5-7 days to maintain freshness.
