April Bloomfield’s rosemary straw potatoes with lemon salt are the definition of crispy indulgence with a vibrant pop of citrus. These are the fries you want when you crave restaurant-level crunch and unforgettable flavor at home—each bite is golden and showered with a fragrant homemade lemon salt. They are my family's go-to for burger nights and the smell of rosemary always brings everyone to the kitchen in anticipation.
I first made these as a side for lamb burgers and everyone fought for the last handful. The lemon salt truly makes these potatoes taste gourmet with almost no extra work.
Ingredients
- Yukon Gold potatoes: Choose firm potatoes with no green spots for great flavor and texture
- Lemon zest: Fresh and brightens the fries Use a microplane for the finest zest
- Sea salt: Look for flaky or kosher salt for best crunch and flavor
- Sunflower oil or a blend of canola and vegetable oil: Pick high smoke-point oils for a golden crisp finish
- Fresh rosemary: Sprigs add a savory aroma Use fragrant bunches with soft needles
Why each ingredient matters—using a high-quality salt or fresh lemon really lifts the whole dish In terms of oils stick with neutral flavors and always buy potatoes that feel dense and not spongy
Step-by-Step Instructions
- Make the Lemon Salt:
- Crush lemon zest and sea salt together with a mortar and pestle until the mixture is deeply fragrant and fine Set aside to dry out if not using immediately so the flavors mellow and intensify
- Prepare the Potatoes:
- Julienne the potatoes into matchstick strips using a sharp knife or mandoline Take your time to keep the pieces even for more consistent frying
- Dry the Potatoes:
- Spread julienned potatoes on a clean towel or paper towels and pat thoroughly to remove surface moisture This is crucial for crispiness
- Heat the Oil:
- Pour oil into a sturdy high-sided pan until about two to three inches deep Heat gradually and check temperature with a thermometer aiming for three hundred fifty degrees Fahrenheit Drop a test potato in and wait for it to rise and color to confirm oil is ready
- Fry in Batches:
- Carefully lower handfuls of potatoes into the hot oil without overcrowding Fry for one to two minutes until golden and crisp Stir occasionally to keep strips from sticking
- Add the Rosemary:
- During the last thirty seconds of each batch drop in rosemary sprigs to infuse aroma Be quick as rosemary cooks fast and can burn easily
- Drain and Season:
- Scoop cooked potatoes and rosemary to a paper towel lined bowl or large bowl Drain excess oil Shower immediately with lemon salt and toss while hot for best flavor distribution
- Serve:
- Enjoy straight away for maximum crunch and aroma These fries shine when freshly cooked and are guaranteed to disappear fast

The rosemary is my favorite touch each time as the sizzling sound and smell of the fresh herbs turning crisp fills the kitchen My niece loves digging for the little shards of rosemary that stick to the fries and says they taste like a grown-up potato chip moment
Storage Tips
Any leftovers should cool completely before storing in an airtight container Fries will lose some crispness but reheat well in a hot oven A quick toss on a sheet pan at four hundred degrees Fahrenheit for five or so minutes revives most of the crunch
Ingredient Substitutions
Try russet potatoes for a thriftier option or fingerlings for a fun look If you do not have fresh rosemary swap in dried but use less as the flavor is stronger No lemon zest around You can use orange or lime zest for a different citrus feel
