Crispy Buttery Cheesy Smashed Potatoes Recipe
There are few things in the culinary world as satisfying as a truly great potato side dish. We’ve all had them – roasted, mashed, fried – but I want to share a method that combines the best of all worlds. This Crispy Buttery Cheesy Smashed Potatoes Recipe delivers fluffy, soft interiors encased in a shatteringly crisp, golden-brown skin, all blanketed in a glorious layer of melted, slightly-browned cheese. It’s a texture and flavour journey that transforms the humble spud into something genuinely special. This was inspired by a dish I had at a little trattoria in Tuscany, where they served simple smashed potatoes drizzled with local olive oil and herbs. I’ve taken that rustic charm and added a decadent, cheesy, buttery twist that we just can’t get enough of at home.
What we’re creating here isn’t just another roasted potato. It’s a deliberate process designed to maximise crispiness. By boiling the potatoes first, we ensure they are tender all the way through. The ‘smashing’ step is where the magic happens; it dramatically increases the surface area, creating countless nooks and crannies. These little ridges and rough edges are what catch the garlic butter and heat from the oven, transforming into an addictively crunchy crust. The final layer of cheese melts into these crevices and forms its own savoury, golden topping.
This potato side dish works beautifully for a Sunday roast, a special weeknight dinner alongside a steak or piece of salmon, or even as the star of a casual meal with a fresh salad. It’s a recipe that always gets compliments, with guests often asking exactly how I get them so unbelievably crispy. Well, today I’m sharing all my secrets.
Recipe Overview
This recipe guides you through a two-stage cooking process to achieve the ultimate textural contrast: a fluffy inside with a deeply crisp, cheesy exterior. The flavour is rich and savoury from the garlic-infused butter and the sharp, nutty combination of cheeses. I’ve found that letting the potatoes steam-dry for a full 5 minutes after boiling is the non-negotiable step for getting that perfect crunch.

Why You’ll Love This Crispy Buttery Cheesy Smashed Potatoes Recipe
- Incredible Texture: The method creates a fantastic contrast between the creamy, fluffy potato centre and the super crispy, craggy edges that are fried in the oven. The melted cheese adds another layer of texture, with some bits getting soft and gooey and others becoming wonderfully crisp.
- Rich, Savoury Flavour: We infuse salted butter with fresh garlic and thyme, which soaks into every crevice of the smashed potatoes as they roast. The combination of mature Cheddar and Parmesan provides a sharp, salty, and nutty finish that is utterly delicious.
- A Straightforward Method: While it takes a little over an hour, the steps are very straightforward. Most of the time is hands-off while the potatoes are boiling and roasting, making it an ideal side dish to prepare while you focus on your main course, like a Garlic Parmesan Chicken Pasta.
- Works Wonderfully for Gatherings: Whether it’s a family Sunday dinner or a casual get-together with friends, these cheesy potatoes are always a hit. They feel a bit more special than standard roasties but are just as comforting.
- Family Tested: My kids, who can be fussy about textures, absolutely devour these. They call them “crispy potato pancakes,” and there are never any leftovers when I make a batch. It’s one of those recipes that everyone seems to love.
Ingredients You’ll Need
For the best results, start with good quality waxy potatoes. Their lower starch content helps them hold their shape after boiling and smashing. When it comes to the butter, I always use a good quality salted butter; the flavour really comes through. I particularly like using a block of Welsh salted butter for its rich, creamy taste.
- 1 kg baby new potatoes or other small, waxy potatoes (like Charlotte or Maris Peer)
- 1 tbsp sea salt flakes (for the boiling water)
- 100g salted butter
- 4 cloves garlic, minced or finely grated
- 2 tsp fresh thyme leaves (or 1 tsp dried thyme)
- 1/2 tsp black pepper, freshly cracked
- 75g mature Cheddar cheese, grated
- 50g Parmesan cheese, finely grated
- 2 tbsp olive oil
- Fresh chives or parsley, finely chopped, for garnish
Adam’s Tip: Don’t be tempted to skip the step of letting the potatoes steam-dry. This is crucial for driving off surface moisture, which is the enemy of crispiness. A dry surface allows the butter and oil to fry the potato rather than steam it.

How to Make Crispy Buttery Cheesy Smashed Potatoes
The process is broken down into a few key stages: boiling, smashing, a first roast for crispiness, and a final roast to melt the cheese into a golden crust. Follow these steps closely, and you’ll be rewarded with the best smashed potatoes.
- Preheat and Prepare: Preheat your oven to 220°C (200°C fan). Place a large, sturdy baking tray in the oven to heat up. This will help the potatoes start crisping immediately.
- Boil the Potatoes: Place the potatoes in a large pot and cover with cold water. Add the tablespoon of sea salt. Bring to a boil and cook for 15-20 minutes, or until they are completely tender and a knife inserts with no resistance.
- Drain and Steam-Dry: Drain the potatoes thoroughly in a colander. Return the empty pot to the low heat for a minute to evaporate any remaining water, then turn off the heat. Tip the potatoes back into the dry pot, cover with a tea towel (not the lid), and let them sit and steam-dry for at least 5 minutes. Give them a gentle shake halfway through.
- Prepare the Garlic Butter: While the potatoes are drying, melt the butter in a small saucepan over a low heat. Add the minced garlic and fresh thyme leaves and cook gently for 1-2 minutes until fragrant. Be careful not to let the garlic burn. Remove from the heat.
- Smash the Potatoes: Carefully remove the hot baking tray from the oven. Drizzle with the 2 tbsp of olive oil. Arrange the steam-dried potatoes on the tray, leaving plenty of space between them. Use the base of a glass or a potato masher to firmly press down on each potato until it’s about 1.5 cm (just over 1/2 inch) thick. Don’t press so hard they disintegrate! I find that a firm, steady press works best.
- First Roast: Drizzle the smashed potatoes generously with the prepared garlic thyme butter. Season with the cracked black pepper. Roast for 20-25 minutes, until the edges are golden brown and starting to look crispy.
- Add the Cheese: Remove the tray from the oven. In a small bowl, mix the grated Cheddar and Parmesan together. Sprinkle the cheese mixture evenly over the top of each potato.
- Final Roast: Return the tray to the oven and roast for another 10-15 minutes, or until the cheese is completely melted, bubbling, and golden brown in spots.
- Serve Immediately: Let the potatoes cool on the tray for a minute or two, which helps them firm up slightly. Garnish with fresh chives or parsley and serve hot.
Tips From My Kitchen
- Hot Oven, Hot Tray: Starting with a preheated oven and a hot baking tray is essential. When the potatoes hit the hot oil, they start searing immediately, which is the first step towards a super crispy base.
- The Steam-Dry Secret: I can’t stress this enough. I learned that letting the potatoes sit in the colander or a dry pot for 5-10 minutes makes a world of difference. The dry, slightly fluffy surface that develops is what allows them to get properly crunchy in the oven.
- Make-Ahead Method: You can boil and smash the potatoes a few hours in advance. Arrange them on the baking tray, cover, and refrigerate. When you’re ready to cook, let them sit at room temperature for 20 minutes, then drizzle with the butter and roast as directed. You might need to add 5-10 minutes to the initial roasting time.
- Storage and Reheating: Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat and bring back some crispiness, place them on a baking tray in a 200°C (180°C fan) oven for 10-12 minutes, or until heated through.
Equipment You’ll Need
- Large saucepan
- Colander
- Heavy-duty baking tray
- Small saucepan
- Potato masher or a sturdy glass
- Grater
Common Mistakes to Avoid
- Overcrowding the Tray: Giving each potato enough space is vital. If they are too close together, they will steam instead of roast, resulting in soggy potatoes. Use two trays if necessary to ensure good air circulation.
- Under-Boiling the Potatoes: The potatoes must be completely tender before you smash them. If they are undercooked, they won’t smash properly and will have a hard, unpleasant texture in the centre. Test with a sharp knife – it should slide in and out with zero resistance.
- Smashing Too Hard: The goal is to flatten the potato to increase its surface area, not to obliterate it into a mash. Apply firm, even pressure until it’s about 1.5cm thick. You want it to hold together but have lots of craggy edges.
Delicious Variations to Try
Once you’ve mastered the basic recipe, it’s fun to experiment. These smashed potatoes are a fantastic canvas for other flavours.
- Spicy Kick: Add 1/2 teaspoon of red chilli flakes to the garlic butter when you’re melting it to infuse the potatoes with a gentle, warming heat.
- Herb Variations: Swap the thyme for finely chopped fresh rosemary, or add some smoked paprika to the butter for a smoky depth.
- Different Cheeses: Try using Gruyère for a nutty flavour, or a spicy Monterey Jack for a bit of a kick. A combination of any good melting cheese will work well here.
What to Serve With This Crispy Potato Side Dish
These cheesy smashed potatoes are incredibly versatile. They are substantial enough to be a main feature but also work as a fantastic accompaniment to many dishes.
- Roast Chicken or Beef: They are a brilliant alternative to traditional roast potatoes for a Sunday dinner. They soak up gravy wonderfully.
- Grilled Steak or Salmon: Serve them alongside a perfectly cooked steak or a fillet of salmon for a meal that feels both rustic and elegant.
- A Hearty Salad: For a lighter meal, pair them with a robust salad. A Classic House Salad with Red Wine Vinaigrette provides a sharp, acidic contrast to the rich potatoes.
- Pasta Dishes: While it might sound like a carb-heavy meal, they are a surprisingly good side for a simple pasta dish, like this Creamy Garlic Penne Pasta, where they can be used to scoop up the sauce.
