✔️ Why should you try it?

• Perfect crispy roast potatoes every time.
• Delicious with any roast dinner.
• Can be frozen and cooked straight from the freezer.

🥘 Ingredients

• Maris Piper Potatoes - the best variety of potato for roasting. You could also use King Edward.
• Olive Oil - the healthiest fat for roasting potatoes.
• Polenta - helps create that crispy crunch on the outside.
• Rosemary - delicately flavours the roast potatoes.
• Sea Salt - essential for seasoning.

🔪 Instructions

The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post

One: Preheat the oven to 220°c (200 fan/ 425F/ Gas 7).

Two: Peel the potatoes and cut any larger ones into two pieces.

Three: Place the potatoes in a pan of salted water and place on the hob on a high heat. Once the water is boiling time 8 minutes.

Four: Drain the potatoes immediately and allow to steam dry in a colander for 5 minutes.

Five: Tip the potatoes back into the pan (make sure there are no remaining water droplets in it) and add the polenta. Give the potatoes a shake to rough up the edges and coat the outsides in the polenta grains.

Six: Put 3 tablespoons of olive oil into a roasting pan and place in the oven for 5 minutes.

Seven: Take the pan out of the oven and tip the potatoes into the hot oil. Coat each one with oil, using a spoon then roast in the oven for 30 minutes.

Eight: After 30 minutes, baste the potatoes and then return to the oven for 15-20 more minutes until golden and crispy. Serve with freshly chopped rosemary and season with salt.

🍴 Serving suggestions

The polenta roasties are great with slow cooker roast beef, air fryer whole chicken, turkey crown, slow cooker lamb breast or roast pork. I also regularly serve them with slow cooker pork chops, savoury mince, baked cornflake chicken nuggets and lamb tagine for filling weeknight dinners.

📖 Variations

• Use semolina flour instead of polenta for coating the potatoes.
• Flavour the roast potatoes with fragrant herbs such as bay, thyme and rosemary. Garlic cloves in their skins can also be added whilst roasting.
• Use goose fat or duck fat instead of olive oil for a richer flavour.
• Try roasting sweet potatoes instead of white potatoes. There is no need to par boil sweet potatoes first.

🧊 Suitable for freezing?

Make the potatoes up to the stage of roasting in the oven and instead of cooking them straight away, open freeze them on a baking tray for 2 hours, and then pop the frozen potatoes into freezer bags for future use.

When you're ready for roast potatoes, just whip them out of the freezer and carry on with the recipe. There is no need to defrost them first, but you will need to add 5 minutes to the cooking time.

I always have a stash of parboiled polenta-coated potatoes in my freezer for quick and easy weeknight dinners.
