I mean the one you do when you want something easy to do, but not when you're tired at the point you microwave a frozen-meal, or just cut down a piece of cheese and put it in a bread
Trim any excess skin you don't wanna eat off of a bunch of chicken thighs
Chuck the thighs in a baking sheet skin up
Wash some potatoes and cut em into wedges. You can peel em if you want
Chuck em in the baking sheet with the chicken
Sprinkle on some salt, and a bunch of other spices that work with chicken and/or potatoes. Garlic powder, pepper, paprika, fuckin dry basil or whatever, idk. Try to get it on both sides of the chicken but if you CBA just get it on the skin side
Drizzle some sunflower or olive oil all over everything. Just a bit is fine
Put the baking sheet in the oven. Doesn't matter if the oven isn't fully heated, it's fine
Come back in like 1h and check if the chicken's done. Come back every 10 min after that until it is
Once it's cooked, you might turn on the fan to crisp up the skin and the potatoes a little more, or maybe not, whatever
It's gonna be the most 7.5/10 dinner but it's like 5 min prep, it reheats fine, and you can walk away and shower or take a nap. You can wash the baking sheet tomorrow, who cares? It was the first 'recipe' I learned how to cook in college, and it's still my go-to lazy weekday recipe.
This is called a tray bake, and it's great. I recommend chucking some (chopped) vegetables in with it: tomatoes on the vine, carrots, broccoli, asparagus, Brussel sprouts, cauliflower, onion, garlic... Limitless possibilities.
You can also do this with salmon (gotta be a bit more careful with timing on that). Or bacon. Or do sweet potato, or pumpkin.
All of this is true, the chicken and potato is just the lazy version. Lots of different vegetables can be added to this but the cooking time gets tricky because a lot of stuff cooks at different rates.
