A Little Story Behind This Recipe

It all started one Sunday when I was preparing dinner for friends — a cozy roast chicken and mashed potatoes kind of evening. I decided to toss a few heads of garlic into the oven “just to use them up,” and they ended up being the star of the meal. The sweet, roasted garlic spread like butter on bread and infused the potatoes with so much flavor that I’ve been obsessed ever since.

Now, I always roast a few extra heads at a time. It’s one of those small kitchen habits that makes weekday cooking infinitely easier and more flavorful.

Why I Love Roasted Garlic

Roasted garlic is one of those magical ingredients that turns something ordinary into something restaurant-worthy.

  • It’s rich, mellow, and slightly sweet — no harshness like raw garlic.
  • It’s versatile — spread on toast, blend into dressings, or stir into soups and sauces.
  • It’s easy to make ahead and stores beautifully in olive oil.

Once you learn how to roast garlic properly, you’ll never be without it.

Ingredients You’ll Need

  • 1 or more heads of garlic – Look for firm, plump bulbs with tight skin.
  • 1–2 tsp olive oil per head – High-quality extra virgin olive oil adds flavor and helps caramelize the cloves.
  • Salt (optional) – A pinch enhances the sweetness.
  • Aluminum foil or a garlic roaster – For easy cleanup and even roasting.

Optional Add-ins

  • Fresh herbs like thyme, rosemary, or sage
  • Cracked black pepper
  • A drizzle of balsamic vinegar for depth

How to Roast Garlic in the Oven

  1. Preheat the oven to 400°F (200°C).
  2. Prepare the garlic heads: Peel off the loose outer layers, leaving the cloves intact. Slice off about ¼ inch from the top of each head to expose the cloves.
  3. Season: Place each head of garlic on a square of foil. Drizzle with olive oil, sprinkle with salt, and add herbs if desired.
  4. Wrap & roast: Seal the garlic tightly in foil packets (or use a covered garlic roaster). Place on a baking sheet and roast for 35–45 minutes, until the cloves are golden and soft.
  5. Cool & serve: Let cool slightly before squeezing the roasted cloves out of their skins.

Quick Tip

For milder flavor, roast at 350°F for 50–60 minutes. For deeper caramelization, go for 425°F for 30–35 minutes.

Alternative Methods

How to Roast Garlic Without Foil

Place the garlic heads in a covered baking dish or small oven-safe pot with a drizzle of olive oil. Cover with a lid or parchment paper and bake as usual.

How to Roast Garlic in an Air Fryer

Cut the tops off the garlic bulbs, drizzle with oil, and wrap in foil. Air fry at 370°F for 20–25 minutes until golden and tender.

How to Roast Garlic on the Grill

Wrap each head in foil with olive oil and salt, and place over indirect heat. Grill for 35–40 minutes, turning halfway through.

Flavor Variations

  • Herb Roasted Garlic: Add a sprig of thyme or rosemary inside the foil for an aromatic twist.
  • Spicy Roasted Garlic: Sprinkle with crushed red pepper flakes before roasting.
  • Balsamic Garlic: Drizzle a few drops of balsamic vinegar on top before roasting for a sweet-tangy flavor.
  • Garlic & Butter: Add a pat of butter over the top for extra richness and golden caramelization.

How to Use Roasted Garlic

Roasted garlic is endlessly versatile. Here are a few of my favorite ways to use it:

  • Spread on toasted baguette or garlic bread.
  • Mash into butter for a flavorful compound butter.
  • Blend into hummus or mashed potatoes for depth.
  • Stir into soups, sauces, or pasta for extra flavor.
  • Mix into salad dressings or vinaigrettes.
  • Add to roasted vegetables or mashed butternut squash for richness.

Expert Tips for Perfect Roasted Garlic

Use fresh, firm garlic heads for the best flavor. Older garlic can become bitter.

Don’t skip the olive oil — it prevents drying and enhances caramelization.

Roasting multiple heads at once saves time and energy — they’ll all keep well for future recipes.

Let the garlic cool before handling; the cloves will pop out easily when gently squeezed.

How to Store Roasted Garlic

Once cool, remove the roasted cloves from their skins and store them one of three ways:

  1. Refrigerator: Store in an airtight container for up to 1 week.
  2. Olive oil: Submerge cloves in olive oil and refrigerate for up to 10 days (do not store at room temperature).
  3. Freezer: Freeze whole cloves or mashed roasted garlic in small portions or ice cube trays for up to 3 months.
