I’m not an empty nester but due to food allergies my wife and I eat different things. I find a good kitchen scale to be a hard requirement. Just take your recipe and scale it down. For pasta, I weigh the entire box, divide by four, weigh out and cook that fourth.

1. Freeze leftovers. If food is too much, put 1-2 meals in a freezer-ready container, put it away. Eat it a few weeks/months later when you’re too lazy to cook.

2. Measure ingredient amounts. Usually, I don’t bother, but if I don’t want leftovers, it’s necessary.

I don’t really consider food I cook to be leftovers. It’s just prepping ahead. That means I don’t have to cook tomorrow.

Some dishes freeze well, so those leftovers can be turned into future meal prep. I liked freezing my chili in silicone muffin tins, then one or two thawed chili pucks was a perfect last-minute meal when I didn’t feel like cooking.

Buy and make smaller portions? Start trading around leftovers with neighbors and friends?

Cook less.

Orrrr

Cook more. Just cook for a weeks worth of food and freeze the left overs.

I had to work on this issue. I used to massively overcook. My house was always the place people just showed up. I had two kids, friends, family, so I was constantly ready to feed an army. Now one is out of the house, the other isn’t home most of the time and husband works evenings. We don’t have company like we used to before Covid, so unannounced guests happen rarely.

I have to be conscious at all times about what I’m cooking. First I had to admit that my perception of how much food I needed was just wrong and could not be trusted. I started using recipes - even for things I know how to make- purely to reference serving sizes. And when all else failed, however much I felt I needed to make, I’d just make half of that

It took some practice but now I make reasonable sized meals and have few leftovers.

Smaller pans may help because it forces you to cook smaller amounts.
Another possible thing to try is to cook 1 pot dishes

I’m not an empty nester just live alone but I just make enough for 2/3 meals so I can have days off from cooking. If a recipe serves like 6/8 I cut all the ingredient measurements in half. I don’t really do box mac and cheese as a side because it’s too much for just me. I suppose you could try making half a box at a time but I don’t know how well the powder would keep.

Lunch the next day. I fail to see the problem. It’s a massive time saver. You need to join a meal prep community to fully appreciate it! It’s a time and money saver

Find an elderly friend nearby you can share with?

Just start feeding the neighbour teenager. Bottomless pit just waiting for all your spare cooking.

Or, halve the recipes. If you don’t cook enough you can always top up with a snack.

I freeze the leftovers, and don’t necessarily eat your same leftovers multiple days in a row. So if I cook three days in a row, that’s probably enough leftovers to rotate between three for a total of nearly two weeks.

I mostly cook stews and sauces, and cook fresh rice or pasta to go with it, because these foods tend to freeze really well.

I use a meal planning app (Mealime), just fill in the amount of people/servings. Pick a few recipes and you have your grocery list for the week. We eat with 2, so I just set my serving size at 4 people and eat the leftovers every other day.

Most dishes that I make is for 3 to 4 days, the is a lower limited on some food I what size and when it is cheapest.
