Baby Yukon gold potatoes are the star of these Lemon Mustard Roasted Potatoes and get tossed in a simple six-ingredient seasoning that features the tang of dijon mustard and the refreshing taste of lemon. Baked to perfection, these crispy potatoes are the ultimate side dish for any main course! 

As an experienced home chef juggling a busy schedule, I’m always on the lookout for simple yet satisfying side dishes to complement our meals. That’s why recipes like these lemon-roasted potatoes are a staple in my side dish recipe collection. 

This easy side dish is made with just SIX simple ingredients, many of which you may already have on hand! A simple blend of olive oil, lemon zest and juice, Dijon mustard, salt, and garlic powder is all you need to bring these baby Yukon gold potatoes to life. You could use a homemade seasoning to amp up the flavor. The Dijon mustard adds a subtle tang, while the freshly grated lemon zest really brightens up the flavor for a potato that is crispy on the outside and tender on the inside.

Optimal Roasting Temperature

In order to get the best texture, you’ll need the right temperature in the oven. I’ve found that the optimal oven temperature for roasting potatoes is 450F. I know that seems high, but unlike roasting at 400 or 425, the higher temperature allows the potatoes to cook with more dry heat and much faster. Because of this, the potatoes don’t get a chance to release much steam, which keeps a nice crispy crust on the outside. Trust me, it’s worth it!

Serve for family dinners, potlucks, a BBQ, or any time you need a delicious side dish during a busy week. Pair them with grilled chicken, roast chicken, steak, a tender piece of salmon, a side salad, or roasted veggies!

Simple Potato Side Dish

• 6 ingredients: You probably already have everything you need to make this, and even if you don’t, you can find everything at the grocery store. 
• Vibrant flavor: The tang of mustard and the brightness of lemon pair perfectly with this tender, creamy potato. 
• Versatile: Roasted potatoes can be served with many different main courses and pair well with lots of different side dishes. 
• Perfect texture: Roasting at a high heat of 450F makes them super crispy and delicious!

Key Ingredients & Substitutions

• Baby Yukon Potatoes – These tiny golden potatoes have a natural creamy inside with a thin skin on the outside. This makes them the best roasting potatoes that get super crispy and hold onto flavor well.
• Olive Oil – Coats the entire surface area of the potatoes to make sure the seasonings stick. The oil also gets hot, which creates crispy skin. You can also use a different oil as long as it has a high smoke point such as avocado oil. 
• Lemon Zest & Juice – Adds a refreshing brightness to the potatoes with the natural flavors and essential oils of lemon. 
• Dijon Mustard – Gives the potatoes a unique and delicious tang that helps cut the tart citrus taste for a balanced flavor.
• Seasonings—Salt and garlic powder balance the flavors even more. Here is where you can get creative and add onion powder, paprika, or black pepper if desired. 

How To Make Lemon Dijon Roasted Potatoes

Prepare for baking: Preheat the oven to 450F. Line a baking sheet with parchment paper. 

Prepare the potatoes: Wash the potatoes thoroughly. You want them to be a uniform size, so cut each in half. If they are on the larger side, quarter them instead. Place them on the prepared baking sheet.

Season potatoes: In a bowl, mix together the olive oil, lemon zest, lemon juice, Dijon, salt, and garlic powder until evenly distributed. Pour over the sliced potatoes and toss until they are coated on all sides. Arrange each potato, so it is cut side down and in one single layer without overlapping. 

Roast: Place in the oven and bake for 40-45 minutes or until the potatoes are crisp and lightly browned. Remove and let cool for 5 minutes before serving with your favorite main course. Enjoy! 

Tips For Roasting Potatoes

• Keep the potato pieces a uniform size. This with make sure that they cook evenly and are finished at the same time. 
• Placing the potatoes cut side down allows contact with the very hot sheet pan. This is what creates that golden brown crust. 
• Arrange the potatoes in a single layer without touching or overlapping. This prevents steaming, which could make the texture mushy or soggy. 
• Baby potatoes are best for this recipe because they have a thin skin and a tender texture on the inside, which helps them roast quicker with a better texture. 

Customize The Flavor

• Swap the Dijon mustard for whole grain mustard to add texture and a different tangy flavor.
• Add dried herbs to the seasoning like basil, rosemary, thyme, or marjoram. 
• If you like potatoes with a kick, add a pinch of red pepper flakes or a dash of hot sauce to the olive oil.
• Grate Parmesan cheese over the potatoes during the last few minutes of roasting for a savory and cheesy flavor.
• Add a light drizzle of honey on top after roasting for a slightly sweet flavor that complements the tangy potatoes.
• Give the potatoes a smoky flavor by adding a bit of smoked paprika to the seasoning blend.

Storing, Freezing & Reheating

Storing: Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. 

Freezing: Allow the roasted potatoes to cool completely, then transfer them to a freezer-safe container or resealable bag. Remove as much air as possible before sealing. They can be frozen for up to 2-3 months.

Reheating: When ready to reheat, preheat your oven to 350°F (175°C). Spread the frozen or refrigerated potatoes in a single layer on a baking sheet lined with parchment paper. Bake for 15-20 minutes or until heated through and crispy.
