Gluten-Free Radish Hashbrowns

Here are my radish hashbrowns, with shredded radishes squeezed dry for extra crispiness, pan-fried until golden brown, and served with a smoky chipotle aioli on the side.

These hashbrowns are a fun low-carb twist on the classic breakfast favorite. My kids were skeptical at first, but now they ask for them on weekend mornings. Plus, they’re way easier to make than you’d think!

What Kind of Radishes Should I Use?

Regular red radishes from the grocery store work perfectly for this recipe, and they’re usually the most affordable option. You can also use daikon radishes if you want a milder flavor, though they tend to be a bit larger so you’ll need fewer of them. When picking out your radishes, look for ones that feel firm and heavy for their size, with smooth skin and fresh-looking greens if they’re still attached. Avoid any that feel soft or spongy, as those are past their prime and won’t give you the best texture for hashbrowns.

Options for Substitutions

This recipe is pretty forgiving when it comes to swaps, so here are some options if you need them:

• Radishes: This is the star of the show, so I wouldn’t recommend substituting them. The whole point is getting that crispy, slightly peppery hashbrown texture that radishes provide when cooked.
• Mayonnaise: You can use sour cream or Greek yogurt instead of mayo for the sauce. Both will give you that creamy, tangy flavor you’re looking for.
• Pickle juice: If you don’t have pickle juice, try using a bit more white wine vinegar or even lemon juice. Start with 1/2 teaspoon and adjust to your taste.
• Chipotle powder: This adds a nice smoky kick, but it’s totally optional. If you don’t have it, you can use cayenne pepper for heat or just skip it altogether for a milder version.
• Extra virgin olive oil: Regular olive oil, avocado oil, or even butter will work fine for frying these hashbrowns. Just use whatever cooking fat you have on hand.
• Egg: The egg helps bind everything together, so it’s pretty important. If you need an egg-free option, try using 2 tablespoons of ground flaxseed mixed with 3 tablespoons of water, but let it sit for 5 minutes to thicken first.

Watch Out for These Mistakes While Cooking

The biggest mistake when making radish hashbrowns is skipping the step of squeezing out excess moisture – radishes hold a lot of water, so use a clean kitchen towel or cheesecloth to wring them out as much as possible, or you’ll end up with steamed, mushy hashbrowns instead of crispy ones.

Another common error is not cooking the shredded radishes long enough in the initial pan step, as they need that full 15-40 minutes to release their moisture and develop a slightly sweet flavor instead of tasting too sharp or bitter.

If you’re using a waffle maker, make sure it’s properly preheated and well-greased before adding the radish mixture, and resist the urge to open it early – letting them cook undisturbed for the full 8-12 minutes ensures they’ll release easily and have that golden, crispy exterior.

Finally, serve these hashbrowns right away while they’re hot and crispy, as they tend to soften as they sit.

What to Serve With Radish Hashbrowns?

Radish hashbrowns make a great breakfast or brunch side, so I love pairing them with classic morning favorites like scrambled or fried eggs and some crispy bacon or breakfast sausage. They also work really well as a base for a loaded breakfast bowl – just top them with a poached egg, sliced avocado, and maybe some crumbled feta cheese. If you’re serving them for dinner, try them alongside grilled chicken or fish with a simple green salad on the side. The creamy sauce that comes with these hashbrowns is so good that you might want to drizzle extra over everything on your plate!

Storage Instructions

Store: Keep your leftover radish hashbrowns in an airtight container in the fridge for up to 3 days. They’re best enjoyed within the first day or two when they still have some texture, but they’ll still taste good after that.

Freeze: You can freeze cooked hashbrowns for up to 2 months. Place them in a single layer on a baking sheet to freeze first, then transfer to a freezer bag. This keeps them from sticking together so you can grab just what you need.

Reheat: To get them crispy again, reheat in a skillet with a bit of olive oil over medium heat for about 3-4 minutes per side. You can also use the oven at 375°F for about 10 minutes, flipping halfway through. The microwave works in a pinch, but they won’t be as crispy.

• Calories: 750-850
• Protein: 8-11 g
• Fat: 75-85 g
• Carbohydrates: 18-24 g

Ingredients

For the hashbrowns:

• 2.2 lb radishes (shredded and squeezed dry for a crispier texture)
• 5 tbsp extra virgin olive oil
• 1 large egg
• 1/2 tsp garlic powder
• salt, to taste
• black pepper, to taste

For the keto sauce (optional):

• 2.1 oz mayonnaise
• 1 1/2 tsp mustard
• 1 tsp pickle juice
• 1/2 tsp vinegar
• 3/4 tsp paprika
• 1/2 tsp garlic powder
• 1/4 tsp onion powder
• 1/2 tsp chipotle powder
• salt, to taste
• black pepper, to taste

Step 1: Prepare the Radishes and Make the Sauce

• 2.2 lb radishes, shredded and squeezed dry
• 2.1 oz mayonnaise
• 1 1/2 tsp mustard
• 1 tsp pickle juice
• 1/2 tsp vinegar
• 3/4 tsp paprika
• 1/2 tsp garlic powder
• 1/4 tsp onion powder
• 1/2 tsp chipotle powder
• salt, to taste
• black pepper, to taste

Using a box grater or food processor, shred the radishes directly onto a clean kitchen towel or cheesecloth.

Gather the corners and squeeze firmly to extract as much liquid as possible—this is crucial for achieving crispy hashbrowns rather than soggy ones.

While the radishes drain, prepare the sauce by whisking together the mayonnaise, mustard, pickle juice, vinegar, paprika, garlic powder, onion powder, and chipotle powder in a small bowl.

Season the sauce with salt and black pepper to taste, then set aside.

Step 2: Sauté the Shredded Radishes

• 2 tablespoons olive oil
• Shredded radishes from Step 1

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat.

Once hot, add the squeezed-dry radishes and cook for 15-20 minutes, stirring occasionally, until they begin to soften and the excess moisture evaporates.

The radishes should start to caramelize slightly at the edges.

I find that cooking them this way removes additional moisture and helps develop a slightly sweet, nutty flavor that complements the tangy sauce perfectly.

Once cooked, transfer to a bowl and let cool for 2-3 minutes.

Step 3: Bind the Radish Mixture

• Sautéed radishes from Step 2
• 1 large egg
• 1/2 tsp garlic powder

Crack the egg into the bowl with the cooled sautéed radishes and add 1/2 teaspoon of garlic powder.

Mix thoroughly until the egg is evenly distributed throughout the radish mixture—this acts as a binder to help the hashbrowns hold together during cooking.

The mixture should feel slightly moist but not wet.

Step 4: Cook the Hashbrowns

• 3 tablespoons olive oil
• Radish and egg mixture from Step 3
• salt, to taste
• black pepper, to taste

For waffle maker preparation: Preheat your waffle maker and lightly grease it with a bit of the remaining olive oil.

Divide the radish mixture into portions and cook for 8-12 minutes until golden and crispy on the outside.

For skillet preparation: Heat the remaining 3 tablespoons of olive oil in a large skillet over medium-high heat.

Form the radish mixture into patties or leave as loose cakes, then cook for 3-5 minutes per side until golden brown and crispy.

Season lightly with salt and black pepper as they cook.

The high heat and oil are essential—they create the crispy exterior while keeping the inside tender.

Step 5: Serve with Spiced Aioli

• Cooked hashbrowns from Step 4
• Prepared sauce from Step 1

Transfer the hot hashbrowns to a serving plate immediately and serve alongside or topped with the prepared sauce from Step 1.

The warm, crispy hashbrowns are best enjoyed fresh, so serve right away to maintain their texture.
