Portland Crab Rosti Ingredients
For the Rosti
- Baking Potatoes – Offers the ideal structure and crispness; russet potatoes can also work well.
- Onion – Adds sweetness and depth of flavor; slice finely for better distribution in the rosti.
- Brown Crab Meat – The star of the dish, delivering rich seafood flavor; fresh crab is best, but canned works in a pinch.
- White Crab Meat – Lightens the texture and gives a delicate balance; additional brown crab can replace it if preferred.
- Green Chilli – Infuses heat and freshness; adjust according to your spice tolerance!
- Mayonnaise – Binds the flavors for a creamy texture; Greek yogurt makes a lighter alternative.
For the Garnish
- Land Cress – Provides a delightful peppery kick and freshness; try arugula or watercress if unavailable.
- Chives – Enhances the flavor with mild onion notes; fresh chives are recommended for the best taste.
- Lemon – Adds a zesty brightness and acidity; a squeeze of lemon juice can further elevate the crab mix.
For Frying
- Vegetable Oil – Essential for achieving that golden crispiness; corn oil is a good substitution, but olive oil has a distinctive flavor.

How to Make Portland Crab Rosti
-
Prepare the Potatoes: Peel and grate the cooled, parboiled baking potatoes into a mixing bowl. Add the finely sliced onion, season with salt and pepper, and mix well until combined.
-
Heat the Oil: In a non-stick frying pan, heat vegetable oil over medium-high heat until shimmering. This ensures a perfect crispy texture when you fry the rosti.
-
Form the Patties: Divide the potato mixture into four equal portions. Form each portion into round patties, ensuring they’re not too thick, to achieve an even cook throughout.
-
Fry the Rosti: Place the patties in the hot oil, frying for about 4-5 minutes until they develop a golden-brown, crispy exterior. Gently flip and repeat on the other side, keeping them warm on a plate.
-
Mix the Crab Filling: In a separate bowl, combine the brown crab meat, finely chopped green chilli, and mayonnaise. Mix well and season to taste, ensuring each bite is flavorful.
-
Serve It Up: On each warm rosti, generously top with the crab mayonnaise, sprinkle the white crab meat, add fresh land cress and chives. Finish with a lemon wedge on the side for that touch of freshness.
Optional: Drizzle with a bit of lemon juice for an extra zing of flavor!

Portland Crab Rosti with Land Cress and Chives Recipe FAQs
What type of potatoes should I use for crab rosti?
The best choice is baking potatoes, which provide the ideal structure and crispness. I often use russet potatoes as a great alternative if baking potatoes aren’t available.
How can I store leftover crab rosti?
Absolutely! Leftover Portland crab rosti should be stored in an airtight container in the fridge for up to 2 days. For optimal texture, reheat them in the oven at 350°F (175°C) for about 10 minutes to regain their crispness.
Can I freeze uncooked crab rosti?
Yes, you can! To freeze uncooked patties, place them on a baking sheet in a single layer until firm, then transfer them to a Ziplock bag. They can be frozen for up to 1 month. When ready to cook, bake them directly from the freezer without thawing.
What should I do if my rosti is turning out soggy?
Sogginess can often be traced back to too much moisture in the potatoes. Make sure the parboiled potatoes are well-drained, and avoid overcrowding the pan while frying. If needed, you can squeeze out excess moisture using a clean dish towel when mixing the potatoes and onion.
Are there any dietary considerations for crab meat?
Very! Shellfish allergies are common, so always check with your guests if they have any allergies before serving this dish. For a vegetarian option, I recommend replacing the crab with sautéed mushrooms or a vegetable medley, which still keeps the flavors exciting.
Can I make these crab rosti ahead of time?
Certainly! You can prepare the rosti mixture and store it in the fridge for up to 24 hours before cooking. Just remember to give it a good mix before forming patties, as settled ingredients may separate. This way, you can save time when you’re ready to impress your guests during a gathering!
