Ingredients needed for Smashed Potatoes with Lemon Dill Cream Sauce
- Baby potatoes - I like to use a tri-color of red, gold, and purple but you can use whatever baby potatoes you like best. Fingerling potatoes also work well!
- Unsalted butter
- Sour cream
- Mayonnaise
- Dijon mustard
- Lemon - Just the lemon zest is used so you'll want to have a citrus zester like this one on hand!
- Fresh dill
- Olive oil
- Garlic-infused olive oil - fresh minced garlic or garlic powder can also be used if you prefer!
- Kosher salt
How to Make Smashed Potatoes with Lemon Dill Cream Sauce
Smashed potatoes are cooked twice: First, they're boiled, then they're roasted. Boiling the potatoes first allows the potato to become fully cooked and tender while retaining their fluffy insides. Then, after coating in olive oil and a generous sprinkle of kosher salt, the potatoes are gently smashed with a fork (or potato masher), drizzled with melted butter, and roasted in the oven until their skins are nice and crispy. The 2-step cooking method produces a fluffy and crispy combination that is really the best of both worlds.
What kind of potatoes are best for smashed potatoes?
Baby potatoes are best for smashed potatoes because they can be boiled and roasted whole, which helps ensure that the texture of the inside of the potato stays soft and fluffy and the outside crisp. Larger potatoes will not cook as evenly when boiled whole and slicing a large potato before boiling will not yield the same texture as the skin helps create a barrier to steam the inside of the potato and prevent them from disintegrating.
For this smashed potato recipe I usually use a mix of red, gold, and purple baby potatoes, but feel free to use whatever baby potatoes are easily accessible to you. This recipe also works really well with fingerling potatoes as an alternative.
Tips for Perfect Smashed Potatoes
- Use baby potatoes of a similar size - Potatoes of a similar size will roast and crisp more evenly than those that are oddly sized.
- Gently pat potatoes dry after boiling - After boiling the potatoes I like to gently pat them dry with a clean kitchen towel so they are not water-logged. Water will encourage the potatoes to steam in the oven rather than crisp, and will make it that much harder for olive oil to coat the skins. Be gentle when patting dry or your potato skins are likely to peel off the flesh.
- Coat the potatoes in oil and salt - After the potatoes have been pat dry to remove excess water, I like to lightly coat them in olive oil and then generously sprinkle them with kosher salt -- This is my go-to kosher salt! The olive oil will help the skins crisp and brown better and helps the salt stick to the skins.
- Roast them in one even layer - The smashed potatoes will take up most of the space on a baker's half-sheet pan, but they should all fit in one even layer.
- Use unsalted butter - I prefer to use unsalted butter for drizzling the insides of the smashed potatoes for two reasons. One, because the skins are already generously coated in salt, and second because the lemon dill cream sauce will add additional salt once added to the potatoes. If you feel that the potatoes would benefit from additional salt, I find that it's best to add it to taste once fully assembled.
- Drizzle with a creamy sauce - The lemon dill cream sauce is one of my favorite ways to enjoy smashed potatoes. Other favorite smashed potato recipes are these Buffalo Smashed Potatoes or these Smashed Potatoes with Avocado Chimichurri Sauce.
How to Make Lemon Dill Cream Sauce
The lemon dill cream sauce is creamy, bright, and tangy owing to a balance of creamy mayo and sour cream, Dijon mustard, lemon zest, garlic-infused olive oil, fresh dill, and just a pinch of kosher salt. Simply mix the ingredients together until combined and top your smashed potatoes!
I prefer to use lemon zest rather than lemon juice in this creamy lemon sauce because the natural oils of the peel offer a pure lemon flavor that nicely balances the flavor of the sauce without overpowering it with acidity. Lemon juice, on the other hand, has a sharp acidity that can sometimes overpower a creamy sauce like this. Although most traditional graters come with a fine grating side, I find that a citrus zester makes a world of difference when zesting citrus -- This is a good citrus zester!
Some of my other favorite easy sauce recipes that would be delicious on smashed potatoes:
- Avocado Chimichurri Sauce
- Romesco Sauce
- Buttermilk Jalapeno Ranch Dressing
- Lemon Herb Tartar Sauce
- Special Sauce
- Basil Walnut Pesto
Serving Suggestions for Smashed Potatoes with Lemon Dill Cream Sauce
These Smashed Potatoes with Lemon Dill Cream Sauce pair perfectly as a side dish to main courses such as roasted chicken, steak, or fish -- I particularly love serving these potatoes with roasted salmon! If there happens to be any leftover sauce, I love to drizzle it over roasted veggies like asparagus, broccoli, or Brussels sprouts.

Description
Looking for a delicious and easy-to-make side dish that's perfect for any occasion? Try these Smashed Potatoes with Lemon Dill Cream Sauce! Baby potatoes are boiled until tender, coated in salt, and smashed before roasting to a golden crisp. The resulting dish includes fluffy and buttery potatoes with delightfully salty and crispy skin. A creamy and tangy lemon dill cream sauce is drizzled over top, ensuring that this easy side dish becomes the highlight of your dinner!
Ingredients
For the smashed potatoes:
- 2 lbs baby potatoes, scrubbed clean (I used tri-color)*
- 1 tbsp olive oil
- 1 ½ tsp kosher salt
- 3 tbsp unsalted butter, melted
For the lemon dill cream sauce:
- 6 tbsp (90 g) sour cream
- 4 tbsp (56 g) mayonnaise
- 1 tbsp garlic-infused olive oil (see notes for substitutions)**
- 1 tbsp fresh dill, minced, plus more to garnish if desired
- Zest of 1 lemon, plus more to garnish if desired
- ½ tsp Dijon mustard
- ¼ tsp kosher salt
- Optional: cracked black pepper, to taste
Instructions
For the smashed potatoes:
- Add the potatoes to a large pot, cover with water, and set to boil over high heat. Cook the potatoes until they are fork-tender. I find in most cases that this takes around 25 minutes from when you first set the pot to heat.
- While the potatoes boil, preheat the oven to 425 degrees Fahrenheit / 220 degrees Celcius. Line a baker's half-sheet pan with parchment paper and set it to the side.
- Once the potatoes are fork-tender, drain them into a large colander. I like to take a clean kitchen towel and give them a gentle pat dry. Don't worry about getting all the water or drying the potatoes individually! You just want to make sure that the potatoes aren't water-logged so that the oil coats the skins properly and they crisp up better.
- Transfer the potatoes to the sheet pan and give them another pat dry if needed. Pour 1 tablespoon olive oil on top of the potatoes and coat by hand (or gently with a wooden spoon if they are too hot to the touch!). Repeat with 1 ½ teaspoon kosher salt, until the potato skins have an oily, grainy texture.
- Using a fork (or a potato masher), gently press down on each potato with the flat portion of the fork tines until the skin breaks and they flatten slightly leaving a crater in the center. Don't worry if some of the potatoes break in half, some of them likely will and they will still be perfectly delicious.
- Drizzle the melted butter over the potatoes, making sure that each crater has butter.
- Roast for 30-40 minutes (depending on size of your potatoes) or until the skins and edges have gone crisp and the lighter-colored potatoes are starting to turn golden.
For the lemon dill cream sauce:
- Combine the sour cream, mayonnaise, garlic-infused olive oil (or olive oil + garlic), Dijon mustard, minced dill, lemon zest, and kosher salt (all of the sauce ingredients) in a small prep bowl. Mix together with a spoon until well combined.
- Once the potatoes have come out of the oven, drizzle them with the sauce. If there's any sauce left over, it's delicious on fish, chicken, veggies, etc.
- Garnish with the optional extra chopped fresh dill, lemon zest, and a few cracks of black pepper if desired.

So. Much. Yes. I'm such a sucker for *anything* involving dill. It's been my favorite herb since I was a kiddo; the smell just *screams* summer time. This is such a great idea for potatoes. Nice to move away from the usual rosemary!
Debra says
Totally agree about potato being a perfect food. Smashed potatoes are a favorite of ours. That creamy dill sauce sounds tasty and makes the dish so beautiful. I can see serving this at brunch instead of hash browns.

Lisa says
You've zoned in on my biggest food weakness... Potatoes. I'll eat them in any form -- and in fact have some baking in the oven as I write this. It's your lemon dill sauce that's really sent me over the edge though. Creamy, herbaceous with a touch of citrusy zing -- this sauce would gild those perfectly crispy, creamy spuds like nothing else. I'm sold.
Tracy says
Oh my gosh, you're right - potatoes DO have super powers!! And yours - this lemon dill cream sauce!! I want to put that on EVERYTHING.
Gloria | Homemade & Yummy says
Potatoes and dill are a winning combination. We have a family recipe that has been enjoyed for at least 50 years. Love the colour of these potatoes...and the perfect side dish to all the BBQ parties
