Frozen chopped onions, soffrito and garlic are a game changer. Eliminate the chopping stage and lots of recipes become 5/15 minute prep quick meals.
I love cooking and have always cooked from scratch and avoided UPFs but the mind space taken up with planning, shopping etc can kill the joy!
A repeating monthly meal plan with summer/winter adaptations and a preset online shopping list takes away all the slog of deciding what to cook. I swap things in and out most weeks if I fancy cooking something different or anyone has a special request but it’s a choice to do that, it’s not a chore any more.
Have some super quick recipes (eg carbonara and salad, stir fry, pasta pesto with peas and broccoli), and prepared meals (home batch cooked or the odd beige meal, pizza etc) every week.
If you don’t want to spend an evening batch cooking every week, at least double up on recipes that freeze well eg spag bol so you have some ready made meals in the freezer.
Try cooking 2 meals in one some nights so you have a low or no prep dinner for the next day (or the day after that, if you want more variety) eg
roast chicken then chicken Caesar salad, cold chicken and bubble and squeak, chicken ramen, curry (the 5 minute Spice Tailor kits are good if you aren’t confident), chicken fried rice etc
Make a spag bol, chilli, cottage pie filling, lasagne at the same time eg fry off the mince, garlic and soffrito then split into two and make a cottage pie filling and one of the others, or split after you have added tomatoes to make spag bol/chilli/lasagne.
While dinner is simmering and you can’t really leave the kitchen, brown off ingredients for a casserole or pie filling to chuck in the slow cooker or oven and cook ready for another evening or to freeze.
Don’t forget simple meat/fish and 2 veg recipes that are low prep, quick and easy. You can add a marinade, glaze or sauce to make it less boring eg peri peri chicken, honey and soy salmon, steak hache and peppercorn sauce (fresh non UPF burgers work instead of steak hache 😂).
