Garlic Confit (Two Ways – Roasted & Traditional French)

ByChef Griffin

Garlic confit is whole garlic cloves cooked slowly until they’re soft, sweet, and spreadable. The raw sharpness is gone, replaced by a mellow, almost buttery richness that makes you want to put it on everything.

I’m showing you two methods here. The first uses whole garlic bulbs wrapped in foil and roasted in the oven. It’s the quickest path to soft, caramelized garlic—no peeling required, no jar of oil to store, just pure roasted garlic ready to use in an hour. You slice the top off the bulbs, drizzle with olive oil, wrap them up, and let the oven do its work.

The second method is traditional French confit—peeled garlic cloves submerged completely in olive oil and cooked low and slow. This is the classic technique. It takes more time and more oil, but you end up with perfectly preserved garlic that keeps for weeks and infused oil that’s just as valuable as the garlic itself.

Both methods give you soft, sweet garlic with that signature velvet texture. The foil method is faster and simpler. The oil method is traditional French technique and gives you more versatility.

The Foil Method

This is roasted garlic at its simplest. Whole bulbs get cut across the top to expose the cloves, drizzled with olive oil, wrapped in aluminum foil, and roasted at 400°F for about an hour. The foil creates a steamy environment that keeps the garlic moist while it caramelizes.

When you unwrap the packet, the cloves squeeze out of their skins like soft butter. The texture and flavor are similar to traditional confit, but you save yourself the time of peeling individual cloves and you don’t need to deal with storing garlic in oil.

This method works perfectly when you need roasted garlic right now—mashed into compound butter, stirred into pasta, spread on bread, or blended into sauces. It’s immediate. No advance planning required.

The Traditional French Confit Method

Real confit means cooking something submerged in fat. That’s the French technique. You peel the garlic cloves, place them in a pan or oven-safe dish, cover them completely with olive oil, and cook them gently at low temperature until they’re soft and golden.

This method takes longer—about 90 minutes to 2 hours depending on your heat source. But the payoff is garlic that keeps in the refrigerator for 2-3 weeks because it’s preserved in oil, plus you get garlic-infused olive oil that you’ll use in everything.

The confit method is better when you want to make a batch that lasts. You can pull cloves out as needed throughout the week, and the infused oil becomes a staple in your kitchen for sautéing, making vinaigrettes, or finishing dishes.

When to Use Each Method

Use the foil method when you’re already using the oven for something else and want roasted garlic to use within a day or two. It’s perfect for dinner tonight—roast the garlic while your chicken cooks, then mash it into the pan sauce or spread it on bread alongside the meal.

Use the traditional confit method when you want to prep ahead and have roasted garlic on hand for the week. Make a big batch on Sunday, store it properly, and you’ve got soft, sweet garlic ready whenever you need it. The infused oil alone is worth the extra effort.

Materials

  • Foil Method
  • 3 garlic bulbs
  • 3 tbsp olive oil
  • Salt and freshly ground black pepper
  • Optional: fresh rosemary or thyme sprigs, red pepper flakes
  • Traditional Confit
  • 35 cloves garlic
  • 2 cups olive oil
  • 4 sprigs fresh thyme
  • 1 bay leaf

Instructions

  • FOIL METHOD (QUICK ROASTED GARLIC):
  • Preheat Oven: Preheat oven to 400°F. Position rack in center of oven.
  • Prep the Garlic: Take each garlic bulb and slice about 1/4 to 1/2 inch off the top to expose the individual cloves. You want to see the garlic flesh, but you're not cutting the bulbs in half. Leave the root end intact—this holds everything together. Peel off any loose papery skin from the outside.
  • Prepare Foil: Tear off a piece of aluminum foil large enough to fully wrap all your garlic bulbs. You want it big enough to create a sealed packet.
  • Season: Place the garlic bulbs cut-side up on the foil. Drizzle each bulb generously with olive oil—about 1 tablespoon per bulb. The oil should pool in the exposed cloves. Season with salt and freshly ground black pepper. If using herbs, tuck a small sprig of rosemary or thyme next to each bulb.
  • Wrap Tightly: Bring the edges of the foil up and over the garlic. Fold and crimp the edges to create a sealed packet. The packet must be completely closed so steam can't escape.
  • Roast: Place the foil packet on a baking sheet and roast for 50-60 minutes. The garlic is done when the cloves are completely soft and golden brown. The bulbs should feel very soft when you gently squeeze them through the foil (use an oven mitt).
  • Cool and Use: Remove from oven and carefully open the foil—watch for steam. Let cool 5-10 minutes. Squeeze the bulbs from the root end and the roasted cloves will slide right out. Use immediately or store in an airtight container in the refrigerator for up to 2 days.
  • TRADITIONAL OIL CONFIT METHOD:
  • Peel the Garlic: Break garlic heads into individual cloves. Place cloves in a heatproof bowl and pour boiling water over them. Let sit 5 minutes—this loosens the skins. Drain and peel each clove. Remove the woody core at the base of each clove if desired.
  • Choose Your Method: You can make confit on the stovetop or in the oven. Stovetop gives you more control. Oven is more hands-off.
  • Stovetop Method: Place peeled garlic cloves in a small saucepan. Add herbs and spices if using. Pour in enough oil to completely submerge the garlic—usually 1.5 to 2 cups. Place over the lowest heat. You want the oil to reach about 200-210°F—barely simmering with just a few tiny bubbles. If it starts bubbling actively, reduce heat immediately. Cook 45-90 minutes, stirring occasionally, until garlic cloves are completely soft and lightly golden. They should be light golden (not dark brown), completely soft when pierced with a fork, and almost falling apart.
  • Oven Method: Preheat oven to 250°F. Place peeled garlic cloves in a small oven-safe dish. Add herbs and spices if using. Pour in enough oil to completely cover the garlic. Cover tightly with foil or a lid. Bake 90 minutes to 2 hours until garlic is completely soft and golden. Check at 90 minutes—cloves should be tender when pierced with a fork.
  • Cool Completely: Remove from heat and let cool to room temperature in the oil.
  • Store: Transfer garlic cloves and oil to a clean jar. Make sure garlic stays completely submerged in oil—this prevents spoilage. Seal and refrigerate immediately. Keeps for 2-3 weeks refrigerated.

Notes

Which Method Should You Choose: Use the foil method when you need roasted garlic fast and plan to use it within 2 days. Use the traditional oil confit method when you want to make a batch that keeps for weeks and want garlic-infused oil as a bonus.
Fresh Garlic Only: Use fresh, firm garlic cloves. Avoid any that are sprouting, soft, or have brown spots. Quality matters since garlic is the star.
Oil Choice: Extra virgin olive oil is traditional and adds its own flavor. If you want pure garlic flavor without olive oil taste, use a neutral oil like avocado oil or grapeseed oil. Avoid oils with low smoke points.
FOIL METHOD SPECIFIC NOTES
Don’t Skip the Foil Seal: The packet must be sealed completely. If steam escapes, the exposed garlic will dry out and burn instead of staying soft and buttery. Crimp those edges tight. 
How Much to Cut Off: About 1/4 inch off the top is perfect. Just enough to expose the flesh. If you cut too little, cloves won’t roast evenly. If you cut too much, cloves dry out.
Oil is Essential: The olive oil keeps the cloves moist and adds flavor. Use about 1 tablespoon per bulb. Don’t skip it. Checking Doneness: The bulbs should feel very soft when you gently squeeze them through the foil (use an oven mitt). If still firm, roast another 10-15 minutes. When done, cloves should be golden brown and completely soft—almost paste-like.
Storage for Foil Method: This version is meant to be used within a day or two. Store squeezed-out cloves in an airtight container in the refrigerator for up to 2 days. They dry out faster than oil-preserved confit because they’re not submerged in fat.
No Infused Oil: This method doesn’t give you garlic-infused oil. If you want infused oil, use the traditional oil confit method.
Scaling: Use as many bulbs as you want. If making a large batch, use multiple foil packets rather than one giant one for even roasting. Three to four bulbs fit comfortably in one packet.
Temperature Variations: You can slow-roast at 350°F for about 75 minutes if you prefer. Lower and slower gives slightly more caramelization.
OIL CONFIT METHOD SPECIFIC NOTES
Temperature is Critical: This is the most important thing. Too hot and the garlic will fry, giving you harsh, bitter flavor and possibly burning. Too cool and it takes forever. You want the oil between 200-210°F with just occasional tiny bubbles. If using stovetop, use your lowest heat setting and watch it closely for the first 15 minutes until you find the right temperature. A thermometer helps but isn’t required—just watch for very gentle bubbling.
Don’t Skimp on Oil: The garlic needs to be completely submerged for even cooking and preservation. If cloves poke out of the oil during cooking, they can brown unevenly or dry out. When storing, make sure they stay submerged to prevent mold.
The Peeling Trick: Soaking cloves in boiling water for 5 minutes makes the skins slide right off. This saves significant time when peeling multiple heads of garlic. You can also lightly smash cloves with the flat side of a knife to loosen skins.
Herbs are Optional but Nice: Fresh thyme is classic and adds an earthy note. Rosemary works but can be strong—use just 1-2 small sprigs. Bay leaf adds subtle depth. Black peppercorns and red pepper flakes give a hint of spice. You can skip all herbs and make plain garlic confit—it’s still excellent.
Storage and Safety: This MUST be stored in the refrigerator and keeps for 2-3 weeks. Garlic in oil at room temperature can develop botulism, which is dangerous. Always refrigerate. If you see any mold, off smells, or the oil becomes cloudy, discard immediately. When removing garlic from the jar, always use a clean spoon to prevent contamination.
The Oil is Just as Valuable: Don’t throw out the infused oil. Use it to sauté vegetables, make vinaigrettes, drizzle over pasta or pizza, or dip bread. It has absorbed all that mellow garlic flavor and any herbs you added.
Yield Depends on Pan Size: The amount of oil needed depends on your pan dimensions. You want just enough to cover the garlic. A small saucepan requires less oil than a wide, shallow pan. Start with 1.5 cups and add more if needed to submerge everything.
Visual Cues for Doneness: Garlic should be light golden (not dark brown), completely soft when pierced with a fork, and almost falling apart. If you can smash a clove easily with the back of a spoon, it’s done. Undercooked garlic will still have some firmness and a sharper flavor.
Stovetop vs Oven: Stovetop is faster and gives you more control—you can adjust heat immediately if oil gets too hot. Oven is more hands-off and heats more evenly, but you can’t adjust temperature as quickly. Both methods work perfectly. Choose based on your preference and what else you’re doing in the kitchen.
What If It Browns: Light golden color is fine and actually adds a slightly nutty flavor. Dark brown means it cooked too hot and may taste bitter. It’s still usable but not ideal. Next time, lower your heat.
Why This is Traditional French Technique: Real confit means cooking something completely submerged in fat at low temperature. This is how the French preserve duck, pork, and garlic. The fat creates an anaerobic environment that, when refrigerated, prevents spoilage and transforms the texture. This is the authentic method.
TROUBLESHOOTING
 Foil Method: Garlic tastes bitter—roasted too hot or too long, or burned. Garlic is dry and shriveled—foil packet wasn’t sealed properly and steam escaped. Garlic isn’t soft enough—needs more time, reseal and continue roasting. Cloves won’t squeeze out easily—let them cool a bit more, or use a fork to help extract them.
Oil Confit Method: If garlic is taking forever to soften, your temperature is too low—increase heat slightly. If cloves are browning quickly, temperature is too high—reduce heat immediately. If oil is bubbling vigorously, it’s too hot and you’re frying, not confiting—remove from heat, let cool, and restart at lower temperature. If stored confit develops an off smell or visible mold, discard it—don’t risk it.
