How Do You Make Creamy Garlic and Herb Mashed Potatoes with Extra Butter?
Short answer: Boil Yukon Gold potatoes in chicken broth, make a garlic-herb cream sauce with butter, sour cream, cheese, and milk, then mash everything together and finish with extra butter for a rich, silky texture.
If you want mashed potatoes that taste as if they came from a steakhouse, this garlic-and-herb version delivers. They’re creamy, savory, and loaded with flavor from fresh garlic, thyme, parmesan, and — most importantly — butter.
Perfect for Thanksgiving, Christmas, Sunday dinner, or any comfort-food craving.
Why These Garlic and Herb Mashed Potatoes Are Better Than Basic Mashed Potatoes
Traditional mashed potatoes are good. This version is next-level because:
- Yukon Gold potatoes add natural creaminess and buttery flavor
- Chicken broth infuses flavor while boiling
- Garlic and fresh herbs add depth and aroma
- Parmesan cheese boosts savory richness
- Extra butter at the end creates a glossy, velvety finish
The result: ultra-creamy mashed potatoes with balanced garlic flavor and a restaurant-quality texture.
Ingredients (Serves 6–8)
- 2 pounds Yukon Gold potatoes, peeled and cut into chunks
- 2 cups chicken broth (for boiling)
- 4 tablespoons butter, divided
- 1 tablespoon fresh garlic, minced
- ½ cup sour cream
- 4 ounces garlic and herb cheese (such as Boursin-style)
- ½ cup whole milk
- 1 teaspoon fresh thyme, finely chopped
- ½ cup freshly grated Parmesan cheese
- AP seasoning, to taste (salt, black pepper, garlic powder, onion powder)
- Extra butter, for finishing
Step-by-Step Instructions
1. Boil the Potatoes in Broth
Direct answer: Simmer Yukon Gold potatoes in chicken broth for 15–20 minutes until fork-tender.
- Place peeled and chopped potatoes in a large pot.
- Pour in chicken broth (add water if needed to fully cover).
- Bring to a boil over medium-high heat.
- Reduce to a steady simmer.
- Cook until a fork slides in easily (about 15–20 minutes).
Why broth matters: It seasons the potatoes from the inside out instead of relying only on salt at the end.
2. Make the Garlic and Herb Cream Sauce
Direct answer: Melt butter, sauté garlic, then stir in sour cream, cheese, milk, thyme, and seasoning until smooth.
While potatoes cook:
- Melt 2 tablespoons of butter in a saucepan over medium heat.
- Add minced garlic and sauté for 30–60 seconds (just until fragrant).
- Stir in sour cream and garlic-herb cheese.
- Pour in whole milk.
- Add fresh thyme and AP seasoning.
- Simmer gently until smooth and creamy.
Do not brown the garlic — burnt garlic tastes bitter.
3. Add Parmesan for Depth
Direct answer: Stir grated Parmesan into the warm cream sauce until melted.
- Add ½ cup freshly grated Parmesan.
- Stir until fully melted and incorporated.
- Taste and adjust seasoning as needed.
Parmesan adds salty, nutty depth that balances the richness.
4. Mash the Potatoes
Direct answer: Drain potatoes, mash by hand, and slowly mix in the cream sauce.
- Drain potatoes thoroughly.
- Return them to the warm pot to release excess steam (30–60 seconds).
- Mash using a hand masher.
- Gradually pour in the cream sauce while mixing.
For best texture:
- Stop once smooth and fluffy.
- Do not use a blender or food processor (it can make potatoes gluey).
Add a splash of milk if they’re too thick.
5. Finish with Extra Butter
Direct answer: Add a generous pat of butter on top before serving.
Let it melt into the hot potatoes for:
- A glossy finish
- Richer flavor
- Creamier mouthfeel
This final step is what makes them feel indulgent and complete.
Pro Tips for Perfect Mashed Potatoes
- Use Yukon Golds for creamy texture and buttery flavor.
- Warm your dairy before adding (prevents cooling the potatoes).
- Mash by hand for the best texture.
- Season in layers — broth, sauce, then final taste adjustment.
- Serve immediately for peak creaminess.
If making ahead, keep warm in a slow cooker on LOW and stir occasionally.
Make-Ahead & Storage
Can You Make Them Ahead?
Yes. Store in an airtight container in the refrigerator for up to 3 days.
To reheat:
- Warm gently on the stovetop over low heat.
- Add 2–4 tablespoons of milk.

Can You Freeze Them?
You can, but the texture may slightly change. For best results, consume fresh.
Variations

- Herb Upgrade: Add chopped parsley or chives.
- Spicy Twist: Stir in cracked black pepper or a pinch of cayenne.
- Dairy-Free Option: Use plant-based butter, unsweetened almond milk, and a dairy-free cream cheese alternative.
