Ingredients
To make these crispy rosemary potato cakes, you will need the following ingredients:
- 3 tablespoons olive oil – Divided, for sautéing onions and frying the cakes
- 1 1/2 cups chopped onion – Yellow or white onions add mellow sweetness
- 1 tablespoon finely chopped fresh rosemary – Fresh is preferred, though dried can work in a pinch
- 3 cups leftover mashed potatoes – Cold, plain or seasoned (avoid instant potatoes for best texture)
- 1 cup panko bread crumbs – For the crispy crust
- Kosher salt and freshly ground black pepper – To taste
These basic ingredients balance texture and flavor, making use of kitchen staples while maximizing leftover value.
Step-by-Step Directions
- Sauté the Aromatics:
- Heat 1 tablespoon olive oil in a medium skillet over medium-low heat.
- Add the chopped onion and rosemary, seasoning with salt and pepper.
- Cook, stirring occasionally, until the onion softens and turns golden—about 7 minutes.
- Transfer the onion and rosemary mixture to a large mixing bowl.
- Mix the Potatoes:
- Add the cold leftover mashed potatoes to the bowl with sautéed onion and rosemary.
- Mix well to thoroughly combine. Taste and adjust seasoning as needed.
- Form the Cakes:
- Spread the panko bread crumbs in a shallow dish.
- Using a 1/3-cup measuring cup, scoop the potato mixture and shape into 12 cakes.
- Press each cake gently into the panko crumbs, coating both sides evenly.
- Fry the Cakes:
- Heat 1 tablespoon olive oil in a large nonstick or cast iron skillet over medium-high heat. Add additional oil as needed throughout the process.
- Place the prepared cakes in the skillet in batches (don’t overcrowd the pan).
- Fry, turning once, until golden brown and heated through—about 8 minutes per batch.
- Remove to a paper towel–lined plate to drain excess oil.
- Serve Hot:
- Serve the potato cakes hot, optionally with toppings such as sour cream, fresh herbs, or a sprinkle of flaky salt for extra flavor.
Expert Tips for Potato Cake Success
- Use Cold Mashed Potatoes: Cold, leftover mashed potatoes hold together best and create a firmer cake that fries nicely. Avoid using hot or freshly-made mash, as it can be too soft and fall apart.
- Season Generously: Mashed potatoes can be bland if underseasoned. Taste your mixture before frying, and don’t be shy with salt and pepper. The addition of sautéed onions and rosemary enriches the flavor profile.
- Get Creative: If you’re a fan of “loaded” potato flavors, try stirring in a handful of shredded cheddar cheese, finely chopped cooked bacon, or sliced scallions for variation.
- Choose the Right Oil: Olive oil is traditional, but for a neutral flavor, use refined coconut or avocado oil. Make sure the oil is hot before adding the cakes to prevent them from absorbing too much oil and becoming greasy.
- Keep Them Crispy: For extra crunch, ensure the panko layer is even and fry over medium-high heat. Avoid crowding the pan to keep temperatures steady.
- Advance Prep: Form the cakes ahead of time and refrigerate up to 1 day before frying. This also helps them firm up and hold shape.
Serving Suggestions and Flavor Variations
These potato cakes are remarkably versatile and can be enjoyed in a variety of ways, making them suitable for breakfast, lunch, dinner, or as a festive appetizer.
- Breakfast Side: Serve alongside eggs and crispy bacon for a hearty start to the day.
- Holiday Leftover Star: Pair with roast turkey, ham, or beef for a creative take on holiday leftovers.
- Appetizer Platter: Offer with dips such as sour cream, apple sauce, or a homemade herby yogurt sauce.

- Mix It Up: Substitute chopped thyme, dill, or chives for rosemary, or use a blend of fresh herbs for added complexity.
- Add Cheese: Stir in grated cheddar, parmesan, or feta to the mashed potato mixture before shaping for a cheesy twist.

Frequently Asked Questions (FAQs)
Q: Can I make these potato cakes gluten-free?
A: Absolutely. Simply use gluten-free panko or substitute with seasoned cornmeal or gluten-free flour blends for the crust.
Q: What’s the best way to store and reheat leftovers?
A: Let cakes cool fully, then store in an airtight container in the refrigerator for up to 3 days. To reheat, place in a 375°F (190°C) oven for 8–10 minutes, or until heated through and crisp, flipping once. Avoid microwaving—reheating in the oven restores their crunch.
Q: My potato cakes keep falling apart. What should I do?
A: Crumbly cakes are often caused by too little binder or too-wet potatoes. Make sure to use cold mashed potatoes. If necessary, add an egg to the mix or a touch of extra panko or flour until the mixture holds together when formed.
What others are reading
Q: Can I use instant mashed potatoes?
A: While possible, potato cakes made with real, homemade mashed potatoes yield a superior texture. Instant potatoes often lack the right starch and cohesion, making the cakes softer and less flavorful.
Q: How can I prevent my cakes from becoming greasy?
A: Always make sure your oil is properly heated before adding the cakes. Use enough oil for a shallow fry, but maintain a steady temperature. Overcrowding the pan can cool the oil and cause soggy cakes.
Q: Can I freeze potato cakes?
A: Yes. Arrange cooked and cooled cakes in a single layer on a baking sheet, freeze until solid, and then store in a freezer-safe bag or container for up to 2 months. Reheat in the oven (do not thaw before reheating) to restore crispness.
Tips for a Perfect Golden Crust
- Use panko breadcrumbs for extra crunch—traditional or seasoned varieties both work well.
- Handle cakes gently during frying and flipping to maintain shape and crust.
- Let the cakes rest on a paper towel or wire rack briefly after frying to maintain maximum crispiness.
