I first made this for a Sunday dinner with my family, and let’s just say there wasn’t a spoonful left. Even the picky eaters couldn’t resist!
Why You’ll Love These Garlic Confit Mashed Potatoes

- Melt-in-your-mouth texture thanks to Yukon gold potatoes
- Rich roasted garlic flavor without any harshness
- Easy to prep ahead (hello, time saver!)
- Perfect for holidays or casual dinners
- Pairs beautifully with steak, roast chicken, or even a cozy veggie dish
What is Garlic Confit Anyway?
Confit means “slow-cooked in fat,” and garlic confit is just garlic cloves roasted low and slow in olive oil. The result? Ultra-soft, sweet, buttery garlic with all the bite mellowed out. It’s addictive—and versatile. Use it in pasta, spread on toast, or swirl it into mashed potatoes like this.
Ingredients for Garlic Confit Mashed Potatoes
- 2–3 heads of garlic, peeled
- ½–1 cup olive oil (enough to cover the garlic in a small baking dish)
- 5 lbs. Yukon gold potatoes, peeled and chopped
- ¼ cup butter, softened
- 1 tsp. salt, plus more to taste
- ½ tsp. black pepper, plus more to taste
- ½ cup milk
- ⅔ cup sour cream
- Fresh thyme (optional, for topping)
Pro Tip: Don’t toss the garlic oil! You can drizzle it over the finished mash or use it to roast veggies.
Step-by-Step Instructions
Step 1: Make the Garlic Confit
- Preheat oven to 250°F (120°C).
- Peel all the garlic cloves and place them in a small oven-safe dish.
- Cover with olive oil.
- Cover the dish with a lid or foil and bake for 2 hours, until garlic is soft and golden.
- Let cool to room temperature. You can refrigerate and use it within 1–2 weeks!
Optional shortcut: Roast garlic whole wrapped in foil at 400°F for 40–45 minutes if you’re short on time.
Step 2: Boil the Potatoes
- Peel and chop Yukon gold potatoes into even chunks.
- Add to a large pot with cold, salted water.
- Bring to a boil and cook until fork-tender, about 15–20 minutes.
And Step 3: Mash It Up

- Drain potatoes and return them to the warm pot.
- Add:
- Several cloves of garlic confit (start with 5–6, add more to taste)
- Softened butter
- Salt and pepper
- Milk
- Sour cream
- Mash until smooth and creamy. Use a potato masher, ricer, or electric hand mixer depending on your texture preference.
Want it creamier? Add a splash more milk or garlic oil.
Step 4: Serve with Flair

- Spoon into a serving dish.
- Drizzle with some reserved garlic oil.
- Sprinkle with fresh thyme or extra garlic cloves on top for drama.
Tips for Creamy, Dreamy Potatoes
- Use room temperature butter and warm milk so they mix in easily.
- Never overmix—this can make them gummy.
- Always taste and adjust seasoning before serving.
- Save extra garlic oil to drizzle over steak, roasted veggies, or even bread.
