There are two “proper” ways to cook frozen hash browns. You can use an Air Fryer to cook hash browns if you have one of these, they cook in about 8-10 minutes at 175C, turning them over half way through. Then, of course, there’s one way to just reheat them and accept it’s food, but not the best way to do it 🙂
You do not need to defrost hash browns before you cook them – cooking from frozen is the usual way. Frozen hash browns are triangle-shaped potato and onion rosti cakes, which have been made and partly cooked before being frozen, so they are already “half cooked” when you open the bag.
To Cook Frozen Hash Browns in a Frying Pan
- Pour a little cooking oil, or lard, into a frying pan (US: skillet). You can use the oil you usually use when you fry chips, or fried eggs. Just regular oil. You just need enough to coat/cover the bottom of the frying pan.
- Put the frying pan on your hob and heat the oil until it you can tell it’s hot. You might hear it, or you might see small bubbles appearing. Make sure your heat is medium, not full on. You don’t want the oil to burn, or the hash browns to cook too quickly.
- Remove all packaging from the hash browns and place them in the frying pan in a single layer, giving yourself enough room to be able to move them about a little, or to turn them over. Fry for 2-3 minutes, then turn them over, repeat until both sides are nicely browned, just how you like them. Expect them to take about 8-10 minutes.
- Turn the hash browns out onto a piece of kitchen paper to drain any excess fat off. Serve.
To Oven Bake Frozen Hash Browns
- Pre-heat your oven to 220°C (200°C for a fan oven), or Gas Mark 7.
- Remove the hash browns from any packaging and place them on a baking tray in a single layer – there’s no need to grease the tray if it’s non-stick or if you’re confident they won’t stick as there will be a residue of fat from their cooking process in the factory. If in doubt, just grease the tray very lightly.
- Place the baking tray on the middle shelf of your oven and bake for 15-20 minutes. Turn them over half way through – the hash browns are cooked when they are the brown colour you want them to be! Check they’re hot in the middle before serving as ovens do vary.
Can You Microwave Frozen Hash Browns?
Ah, there’s a question! Frozen hash browns can be cooked in a microwave oven, but they won’t brown more than the colour they start in the packet. Here’s how to cook has browns in the microwave:
- Remove all packaging and lay your hash browns down in a microwave safe dish that has a lid. The lid will retain the moisture, it’s optional if you have no lid, but they will come out a little drier.
- Microwave on full power (800 watts microwave) for 1½ minutes, then turn them over. Repeat until you feel they’re “good enough to eat” which will be between 4 and 6 minutes, depending on how many you are microwaving, the power of your microwave and the size/shape of dish or mug you are cooking them in. I often cook hash browns in a mug as I’m just cooking two and they fit!
- Leave the hash browns to one side for a minute or two to “settle”.
Hash browns will ALWAYS look and taste better if you have managed to fry, bake or Actifry them. But if that’s not an option, then it’s possible to use a microwave to cook them but you will have to accept that you won’t get the same experience, but they are at least edible and safe!
Most of the time I use the microwave to cook hash browns because it’s quick and clean and unfussy!
