Creamy, rich potato gratin with onions. Soft baked potato slices with a generous crispy cheese top. Only a handful of ingredients needed.
Whenever I have little time on hands (which is most of the time), I like to make quick and easy dishes for dinner. My chicken quinoa salad and stir fry fish udon are dishes that are served quite often in my home. The bf usually makes these super simple sausage ramekins, which I love just as much. So if you’re anything like us, fancy roasted chicken with homemade potato wedges just aren’t things you can eat often. BUT because you don’t have a lot of time, doesn’t mean your dinner can’t be delicious. Right?! For me, food is my peace-and-quiet-lets-enjoy-moment 😀 So today, I’m sharing this super simple, creamy, cheesy onion and potato gratin with you 🙂
So to make this dish, all you need are these 6 ingredients:
- Grated cheese
- Pepper and salt (these shouldn’t even count as ingredients)
The most ‘important’ part to this dish are the potatoes (obviously). First, don’t get store-bought pre-cut potatoes. I’ve tried. They’re not that good and way too thick. Which brings me to my second tip: Slice your potato’s as thin as possible. You need to do this for two reasons:
- Maximum flavor
- Quick cooking
I guess that latter is the most important reason, right? 😉
As for the onions, slice them as thick or thin as you’d like. It all depends on your taste. If you like sweet and soft onions, slice the onions as thin as possible. If you like more texture and a more prominent onion-flavor, slice them a bit thicker. And if you have time, you can even fry the sliced onions until lightly golden brown before adding it to the gratin. It adds more flavor! 😀 But like I said, “if you have time”.
To assemble the dish, make layers of potato slices, sliced onions, and pepper and salt. Once you’ve poured the cream on top, you can pop it in the oven! Yes, without the cheese. You will add the cheese later on to prevent it from burning. No one likes burnt cheese. Bake the dish 40-50 minutes depending on the thickness of your potatoes. Do some other stuff in the mean time 😉 Then, add the cheese on top and bake for another 5-10 minutes or until the cheese is melty and beautiful golden brown. I love melty cheese. ♥_♥ Let the dish cool slightly before serving or cool completely and store in the fridge to eat it later on. Whatever floats your boat ^^ Enjoy!
