Keto Hash Browns

Crispy keto hash browns made with coconut flour and a secret potato flavor extract. No cauliflower, no cabbage. Just three ingredients that shred on a cheese grater and fry up exactly like the real thing.
I started making these back in 2021, and they’ve become a Sunday morning staple. The idea was simple: coconut flour, xanthan gum, and hot water form a dough you can actually shred on a box grater. Real shreds, not pressed patties or cauliflower mush.
The texture is what sold me. When you fry these in avocado oil, the outside crisps up golden and almost crackles when you bite in. The inside stays soft, just like the diner version I grew up eating. I’ve tested this recipe dozens of times, adjusting the coconut flour ratio and the oil temperature until the crunch was right.
What makes this different from every other low carb version is the shredding technique. Most recipes press cauliflower or radish into a patty shape. That gives you a fritter. When I shred this dough through a box grater, you get actual strands that crisp individually in the oil. Reader Kay tried it and confirmed: ‘It actually grated into neat shreds.’ That’s the texture I was going for.
The secret weapon is OOOFlavors mashed potato extract. I use 30 to 40 drops per batch, and it transforms the flavor completely. Without it, you’ve got a perfectly crispy coconut flour patty. With it, you’ve got something that genuinely tastes like potatoes. I developed this use case myself (the product page doesn’t even suggest it) and it’s become my favorite kitchen hack.
These are naturally dairy-free since there’s no cheese or butter in the dough. I fry mine in avocado oil, but you could use ghee or beef tallow for a richer flavor. Nathan from the comments tried duck fat and an air fryer. The flavor was good, but he found pan-frying works better than air frying for this dough. The coconut flour base needs direct contact with hot oil to crisp properly.
I serve these alongside crispy air fryer bacon, sheet pan eggs, or a loaded breakfast bowl for a full keto breakfast. They also go well with air fryer breakfast sausage if you want more protein on the plate.
One thing I love about this recipe is how fast it comes together. While your bacon cooks, you can mix the dough, shred it, form the patties, and start frying. No wringing out cauliflower in cheesecloth. No pre-cooking vegetables. Just mix, shred, fry.
For the crispiest result, keep your patties on the thinner side and don’t pack them tight. I want the hot oil to reach the interior, not just the surface. Shake the skillet as you fry and let the oil splash over the edges. That’s how you get those golden, crunchy edges.

Step by Step Instructions
Step by Step Instructions
Form a hash brown patty
Portion the shreds into four parts. Gently mold each one into a loose patty. Don’t pack it too tight – you want the oil to reach the inside for a crispy result.
Fry it
Add enough avocado oil to a small skillet to cover the hash brown patty halfway. Heat over medium heat. Place the hash brown patty into the hot oil and fry until golden brown (2-3 minutes). Flip over and fry the other side. Gently move the skillet back and forth on the burner to slosh hot oil over the sides and top of the hash brown. This will help crisp it up further. Remove from the skillet and place on a paper towel lined plate to absorb excess oil. Serve immediately.

Can I make these in the air fryer?
I've had readers try the air fryer, and the results aren't great with this coconut flour dough. Nathan from the comments tested it with duck fat and ended up switching back to pan-frying. This dough needs direct contact with hot oil to crisp properly, which is why skillet frying is my go-to method for these keto patties.
Where do I buy the mashed potato flavor extract?
I buy mine from OOOFlavors. They sell it on their website and it's also on Amazon. Use code Ketofocus-10 for 10% off on their site. I've been using this brand since I developed the recipe, and a single bottle lasts me months since you only need 30 to 40 drops per batch.
Can I skip the potato extract entirely?
Yes. Without it, you'll get crispy coconut flour patties that taste more neutral. I'd add onion powder and garlic powder to the dough if you skip the extract. Reader Kay does this and said the flavor was great. The texture stays the same either way.
Are these dairy-free?
Yes, they're naturally dairy-free. There's no cheese or butter in the dough, and I fry mine in avocado oil. You could also use coconut oil or beef tallow. I developed this recipe without dairy from the start, so you don't need to make any substitutions.
Can I use these in a breakfast casserole?
I haven't tried them in a casserole myself. Reader Chris asked the same question. My guess is the shreds would soften since they won't have direct oil contact. If you try it, I'd par-fry them first for some crunch, then layer them in. Let me know how it turns out so I can update the recipe.
What can I use instead of coconut flour?
Coconut flour is what gives these their texture, so it's my first choice. I've tested almond flour, but it absorbs moisture differently and the dough doesn't shred as cleanly. If you go with almond flour, use about double the amount and expect a slightly denser result.
What can I use instead of xanthan gum?
I've tried psyllium husk powder and ground chia seeds as substitutes. Both hold the dough together, but the texture changes slightly. Psyllium gives a chewier result, and chia seeds add a little crunch. My preference is still xanthan gum for the closest match to real shredded texture.
How should I store leftovers?
I keep mine in an airtight container in the fridge for up to 3 days. Reheat them in a hot skillet (the microwave makes them soggy). They crisp back up in about 2 minutes per side. I also pair reheated ones with breakfast quesadillas for a quick lunch.
You grate the dough like cheese and it just... becomes hash browns. Never made anything like this and I was fully convinced it would disintegrate the second it hit the oil, but they held together and got genuinely crispy. Four stars because I burned my first batch misjudging the oil temp, but that's a me problem.
Burned my first test batch too. Medium heat and I drop a tiny piece of dough in first, if it sizzles immediately the oil's ready. Medium-high just scorches the outside before the inside sets.
Added onion powder to the dry mix and fried them in butter instead of avocado oil. Way more depth of flavor, tastes like something from an actual diner. I cannot stop making these.
Butter browning on coconut flour is on another level. The avocado oil keeps the flavor neutral but butter actually adds to it. Stealing this.
Used the large holes on my box grater instead of the fine side and got actual texture for once, not the flat crispy pancake situation I kept getting before.
Large holes all the way. The fine side compresses the dough and you end up with something closer to a pancake. The shreds need room.
Made these for meal prep this week. Didn't think coconut flour would pull off hash browns but it actually works.
Right? Coconut flour binds weirdly well here. I make a double batch every Sunday.
You are a genius!!! Followed your directions - didn’t have the potato extract, so used a little onion & garlic powder for some flavour. It actually grated into neat shreds!
I actually just fried a handful of the shreds (so they were all crispy all over) and placed on bottom of bowl with eggs & salmon on top. Absolutely divine and giving some crunch I’ve been sorely missing.
Onion and garlic powder is a solid swap for the flavor. And that bowl, crispy shreds as the base under eggs and salmon, that's a full breakfast right there.
If the shredded ‘potatoes’ are cooked until crispy, will they say crispy if cooked in a breakfast casserole?
I haven't tried them in a breakfast casserole. Let me know if you do and how it turns out so I can update the recipe information for others.
I tried doing these mixing duck fat in with the shredded "potatoes" and air frying them (decided to skip my original step idea of freezing first).
The result was essentially that it did not work. Ended up just pan frying as you said to do and that worked better. Hopefully the frozen ones will work out a bit better.
Regardless, the flavor was good. Definitely not the same as actual hash browns, but close enough to make me happy. I had one with some jalapeno ranch on top and it was yummy.
Yeah, this dough needs direct oil contact to crisp up right. Duck fat in the skillet would probably be great though. Jalapeño ranch on top, I'm stealing that.
I am going to try these tonight, though I think I will mix the shredded "potato" with duck fat, form them into patties, and then freeze them for a bit. From there, I am going to try cooking them in the air fryer.
Duck fat is a good call. Air fryer is tough with this dough (it needs direct contact with hot oil to crisp). Freezing first to firm them up, that part I like.
I made them and used the mashed potato extract. Used 40 drops. Couldn’t taste it. They didn’t seem cooked throughout so I guess I didn’t have them loose enough. Do you think just frying them in a pan without forming the patties would work?
Yes, try to do a looser patty too. I have just taken a handful of the shreds and placed them in the skillet.
Now if you can figure out how to do something similar to make mashed potatoes!
Ha, working on it. Those mashed potato drops from OOOFlavors actually work in cauliflower mash too if you need something to hold you over.
Not exactly like hash browns but pretty close! I used beef tallow and the potato extract.
Beef tallow plus the drops is the closest you're going to get. I'd call that a win.
