Mary Berry Potato Rosti With Onion Recipe

Ingredients Needed

Mary Berry’s Potato Rosti with Onion is a simple yet flavorful dish that highlights the natural goodness of potatoes, paired with the rich, slightly sweet flavor of onions. Here’s what you’ll need:

• 4 large potatoes (preferably waxy potatoes like Maris Piper or Charlotte): Waxy potatoes are key for achieving a rosti with a nice texture-crispy on the outside while soft and tender on the inside. Their lower starch content helps the rosti hold together without falling apart during cooking.
• 1 large onion: The onion adds a deep, savory sweetness to the rosti. It can be sautéed beforehand to bring out its sweetness or grated for a more subtle flavor integration.
• Butter (about 2 tablespoons): Butter helps achieve that golden, crispy exterior while adding a rich flavor to the rosti. You can opt for a mix of butter and oil if you prefer a more neutral fat or want to raise the cooking temperature slightly without burning the butter.
• Oil (about 1 tablespoon): Oil ensures the rosti cooks evenly and prevents the butter from burning at higher temperatures. Vegetable oil or sunflower oil works well here.
• Salt (to taste): Enhances the flavors and brings out the savory notes of the potatoes and onions.
• Black pepper (to taste): Adds a subtle, peppery kick, balancing the richness of the butter and the sweetness of the onions.
• Fresh parsley (optional, for garnish): A sprinkle of fresh parsley adds a pop of color and freshness to the dish. It’s not essential, but it does elevate the dish aesthetically and adds an herbaceous note to complement the potatoes.

Equipment Needed

While Mary Berry’s Potato Rosti with Onion is a simple dish to prepare, there are a few essential tools that will help make the cooking process smoother and more efficient:

• Grater or Food Processor: You’ll need a fine grater to grate the potatoes and onions. A food processor with a grating attachment is an excellent option if you’re short on time or don’t want to strain your wrists. The goal is to shred the ingredients into thin, evenly-sized strips that will crisp up well when cooked.
• Large Frying Pan (ideally non-stick): A non-stick pan is ideal because it helps prevent the rosti from sticking to the pan as you cook it. A frying pan with a flat bottom gives you the maximum surface area for an even, crispy rosti.
• Spatula or Fish Slice: A wide, flat spatula or fish slice is helpful for flipping the rosti without it falling apart. If you have a thinner spatula, you can use it to slide under the rosti carefully before turning it over.
• Large Bowl: To mix the grated potatoes and onions together, you’ll need a large bowl. This allows you to evenly distribute the ingredients and ensure that the rosti mixture is well-combined.
• Tea Towel or Paper Towels: After grating the potatoes and onions, it’s essential to squeeze out any excess moisture. A tea towel or paper towels are the best way to do this, ensuring your rosti stays crispy instead of soggy.
• Lid for the Frying Pan (optional): While this isn’t strictly necessary, covering the rosti with a lid during the cooking process can help ensure it cooks through without burning the outside.

How To Make Mary Berry’s Potato Rosti With Onion

Making this crispy, golden potato rosti with onion is quite simple and doesn’t require a lot of advanced techniques. Here’s a step-by-step guide:

1. Prepare the Potatoes and Onions:
   Begin by peeling the potatoes. Once peeled, grate them using a coarse grater or food processor. Immediately place the grated potatoes into a bowl of cold water to remove any excess starch. After soaking for a minute or two, drain and then pat the potatoes dry with a tea towel or paper towels. This step is crucial for achieving that crispy exterior.

   Next, peel and grate the onion. If you prefer a milder flavor, you can sauté the grated onion briefly in a little butter or oil until softened, but grating it raw will give you a more intense flavor.

2. Combine the Ingredients:
   In a large mixing bowl, combine the grated potatoes and onions. Add salt, pepper, and any optional seasonings you like. Mix well, ensuring the ingredients are evenly distributed. You can also add a small amount of flour here if you prefer your rosti to have a slightly firmer texture.

3. Cook the Rosti:
   Heat the butter and oil in a large non-stick frying pan over medium heat. Once the fat has melted and is sizzling, spoon the grated potato and onion mixture into the pan. Flatten it out with the back of a spoon to form an even, compact layer. It’s important to not overcrowd the pan; if the mixture is too thick, you may need to make it in batches.

   Cook for about 5-7 minutes on one side until the rosti is golden and crispy. Use a spatula to check the underside.

   When it’s ready, carefully flip the rosti over. If it’s too large to flip in one go, you can cut it into sections for easier handling.

4. Finish Cooking:
   Once flipped, reduce the heat slightly and cook the other side for another 5-7 minutes, ensuring that both sides are evenly crisp and golden brown. If you want the rosti to be particularly crispy, you can press it down gently with the spatula during cooking to encourage more even browning.

5. Serve:
   Once your potato rosti is cooked to perfection, slide it out of the pan onto a serving plate. Optionally, garnish with freshly chopped parsley for a touch of color. It’s best served immediately while the rosti is still crisp.

Expert Tips

To ensure your Potato Rosti with Onion turns out perfectly every time, here are a few expert tips:

• Choose the Right Potatoes: For the best texture, use waxy potatoes. These potatoes have the right balance of moisture and starch that gives you a crispy exterior while keeping the interior soft and fluffy.
• Squeeze Out Excess Moisture: After grating the potatoes, make sure to squeeze out as much moisture as possible. This is one of the key secrets to getting a crisp rosti. If there’s too much moisture, your rosti could become soggy instead of crispy.
• Season Well: Don’t be shy with the salt and pepper. These simple seasonings enhance the flavors of the potatoes and onions and are essential for making the dish delicious.
• Temperature Control: Make sure your pan isn’t too hot, as this could cause the rosti to burn before it cooks through. Medium heat is ideal for getting that golden-brown exterior while ensuring the inside is soft and tender.
• Make It in Batches: If you have a smaller pan, consider making smaller individual rostis. This ensures they cook evenly and gives you more control over the crispiness.
• Consider Adding Cheese or Herbs: While the recipe is delicious as is, you can add a bit of grated cheese to the mixture for extra flavor. Parmesan or cheddar work beautifully. Fresh herbs like thyme or chives can also elevate the dish.

Mary Berry’s Potato Rosti with Onion is a fantastic, versatile dish that is sure to impress with its crispy texture and rich, savory flavor. By using the right potatoes, ensuring the mixture is dry, and carefully cooking the rosti to golden perfection, you can achieve a dish that is both satisfying and comforting.

Whether you serve it as a breakfast treat, side dish, or a savory snack, this simple yet elegant recipe is a great addition to any meal. With a few expert tips, you’ll be able to perfect your rosti-making skills and enjoy this crispy delight any time you like!.

Easy Recipe Variations For Mary Berry’s Potato Rosti With Onion

Mary Berry’s Potato Rosti with Onion is a delightful and versatile dish, perfect for breakfast, lunch, or dinner. It’s crispy on the outside, tender on the inside, and loaded with savory flavors.

While the classic recipe is delicious on its own, there are many ways to modify and adapt the dish to suit your taste preferences or to make it more exciting. Here are a few easy variations to try:.

1. Cheese and Herb Rosti

   Adding cheese to your potato rosti is a great way to elevate the dish. Grated cheese, such as cheddar, Gruyère, or even Parmesan, can be mixed directly into the potato mixture or sprinkled on top as it cooks.

   The melted cheese forms a golden, crispy crust and adds an irresistible savory depth. Fresh herbs like chives, rosemary, or thyme can be finely chopped and added to the mixture to enhance the flavor profile with a fragrant, earthy aroma.

2. Bacon or Ham Rosti

   If you love a bit of protein in your breakfast or brunch, incorporating bacon or ham into the rosti mixture is a great way to add a salty, savory bite. Fry chopped bacon until crispy and then mix it into the grated potatoes and onions before cooking. Alternatively, diced cooked ham can be added for a milder option, providing a delicious contrast to the richness of the potatoes.

3. Spicy Rosti with Chilli

   For those who love a bit of heat, adding chopped fresh chilli or dried chilli flakes to your rosti can give it a spicy kick. Combine with a squeeze of lime juice for a zesty contrast or some cumin to introduce a warm, earthy spiciness. This version pairs wonderfully with a cooling dollop of sour cream or yogurt on top.

4. Vegan Rosti

   If you’re looking for a vegan version of the dish, it’s incredibly simple to make. Replace the butter with olive oil or another plant-based alternative for frying.

   You can also skip the eggs if desired, as the potatoes themselves will hold together well during cooking, especially if you finely grate them. For added flavor, incorporate nutritional yeast to give the rosti a cheesy taste without the dairy, and season generously with smoked paprika or turmeric for an extra layer of flavor.

5. Vegetable-Rich Rosti

   Another healthy twist on the traditional recipe involves adding extra vegetables. Grated carrots, zucchini, or parsnips make great additions, enhancing the texture and flavor of the rosti while boosting its nutritional value. You can also try incorporating leafy greens like spinach or kale, sautéed until wilted, to give the dish a fresh, vibrant kick.

6. Smoked Salmon Rosti

   For a more luxurious take, top your potato rosti with smoked salmon and a dollop of crème fraîche or sour cream. A sprinkle of fresh dill or capers would round out the flavors and give the dish an elevated, sophisticated twist-perfect for special occasions or a brunch gathering.

Best Practices To Store Leftovers

If you happen to have leftovers of Mary Berry’s Potato Rosti with Onion, you’ll want to store them properly to maintain their deliciousness. Here are some tips for storing your leftovers:

1. Cooling Down

   Before you store your rosti, always let it cool down to room temperature. Placing hot food directly into the fridge can cause condensation, leading to sogginess. Allowing the rosti to cool also helps prevent any bacterial growth that can occur when food is stored too warm.

2. Storage Containers

   For the best storage, place your leftover potato rosti in an airtight container. This helps to preserve both the texture and flavor.

   You can separate individual portions of the rosti by wrapping them in parchment paper or wax paper before placing them into the container. This will also prevent the rosti from sticking together.

3. Refrigeration

   Store the rosti in the refrigerator for up to 2-3 days. The crispy texture might diminish slightly, but the flavors will still remain intact. Be sure not to store it for longer, as the potatoes may spoil and become unsafe to eat.

4. Freezing Leftovers

   If you want to keep your rosti for a longer period, freezing is an excellent option. Wrap the rosti in plastic wrap or aluminum foil and place it in a freezer-safe bag or container.

   When properly stored, frozen potato rosti can last for up to 3 months. To reheat, simply thaw in the fridge overnight and then reheat in a hot pan or oven until crispy again.

5. Reheating

   To regain some of the original crispiness, avoid microwaving the rosti as it can turn soggy. Instead, reheat in a dry frying pan over medium heat or place it in an oven preheated to 350°F (175°C).

   This will help retain the crispy outer texture that makes the rosti so appealing. A quick spray of oil or a dab of butter will help add a bit of extra crunch.

What Goes Well With Potato Rosti With Onion

Mary Berry’s Potato Rosti with Onion is a versatile dish that pairs beautifully with a variety of accompaniments. Here are some suggestions on what goes well with it:

1. Eggs

   A classic pairing for potato rosti is eggs, especially a perfectly fried or poached egg. The richness of the yolk adds a lovely contrast to the crispy texture of the rosti.

   You can go for a sunny-side-up egg or scrambled eggs if you prefer a different texture. Adding a sprinkle of fresh herbs or a dash of hot sauce on top can further enhance the dish.

2. Sautéed Greens

   Leafy greens, such as spinach, kale, or Swiss chard, sautéed with garlic and olive oil, make a great side dish to balance the heaviness of the rosti. The fresh, slightly bitter flavor of the greens cuts through the richness, creating a well-rounded meal.

3. Salmon or Smoked Salmon

   A luxurious addition, smoked salmon pairs exceptionally well with the crispy potato rosti. The smoky, delicate flavor of the fish contrasts wonderfully with the hearty potatoes. A drizzle of lemon juice and a few sprigs of dill will tie everything together for a sophisticated meal.

4. Grilled Meat or Sausages

   Whether it’s crispy bacon, sausages, or grilled chicken, a savory meat side dish complements the potato rosti beautifully. The rich, meaty flavors balance the starchy potatoes, making it a hearty, satisfying meal. A light gravy or mustard on the side can add an extra layer of flavor.

5. Tomato Salad

   A refreshing tomato salad with balsamic vinegar, olive oil, and a sprinkle of fresh basil or parsley offers a fresh and tangy contrast to the rich rosti. This adds a burst of color and freshness to your plate, making for a more balanced dish.

6. Sour Cream or Yogurt

   A dollop of sour cream or Greek yogurt on top of your potato rosti can add a smooth, creamy element that complements the crispiness of the rosti. If you like a bit of zing, try a flavoured yogurt, such as a garlic or lemon-infused variety.
