What to Cook With What You Have at Home – and How to Plan the Week Around It

The fridge isn't empty, but nothing in it looks like dinner. There's some rice, two eggs, a pepper that needs using, half a tin of chickpeas. The easy answer is a takeaway or another trip to the shop. The better answer is usually already there – you just need a way to see it.

This guide gives you a simple formula for turning random ingredients into a meal, a combination table for quick ideas, and a way to go one step further: planning several dinners around what you have, so the shopping list only covers what's missing.

Step 1. Take a quick look before you decide

Spend a couple of minutes on a quick check. Open the fridge, freezer and cupboards and sort what you see into three groups:

• Use first – things that will spoil soon: soft vegetables, open dairy, cooked leftovers, fresh herbs.
• Basics – rice, pasta, potatoes, flour, eggs, tins, frozen vegetables.
• Flavour – spices, sauces, stock, garlic, onions, cheese, lemon.

Dinner starts with the "use first" group. That's what saves food from the bin.

Step 2. Use the formula: base + protein + vegetables + flavour

Most everyday dinners follow the same pattern. Pick one from each column:

• Base: rice, pasta, potatoes, bread, couscous, noodles, tortillas.
• Protein: eggs, beans, lentils, chickpeas, chicken, minced meat, fish, tofu, cheese.
• Vegetables: anything fresh or frozen – especially the ones that need using.
• Flavour: a sauce, spice mix, stock, garlic and onion, a squeeze of lemon, herbs.

You don't need all four every time, but checking each one stops dinner from feeling like "just rice".

Combination table

Treat the table as a starting point. If someone at the table has an allergy, check every ingredient – especially sauces, spice mixes and stock, which often contain allergens.

Step 3. Keep a small rescue kit at home

A few long-lasting items make almost any leftover into a meal:

• a starch: rice, pasta or potatoes,
• tins: tomatoes, beans or chickpeas,
• eggs,
• onions and garlic,
• frozen vegetables,
• one or two flavours you like: stock, a spice mix, soy sauce, pesto.

You don't need a big supply. Just restock the kit when something runs out.

Step 4. Go from "tonight" to "this week"

Answering "what tonight?" is useful. Planning the week around what you have is more useful, because it also tells you what not to buy.

1. Write down what you have, starting with the "use first" group.
2. Give each of those items a dinner early in the week. The soft pepper goes into Monday's fried rice, the open cream into Tuesday's pasta sauce.
3. Fill the rest of the week with dinners that use your basics and need only a few fresh items.
4. Make the shopping list from the gaps – only what the planned dinners still need.

Example: a week built around what you have

Say you have rice, eggs, half a bag of pasta, tinned tomatoes, a pepper and some cream. Monday is fried rice with egg and the pepper. Tuesday is pasta with a tomato and cream sauce. Wednesday uses beans from the cupboard in wraps. For Thursday and Friday you buy only what those two dinners need – and nothing you already have.

Step 5. Keep track of what you have

The hardest part of cooking from what you have is remembering what's there. A few habits help:

• Put new shopping behind the older items, so older food gets used first.
• Keep leftovers in see-through containers at eye level.
• Keep a simple list of what's in the freezer and update it when you take something out.
• Before every shop, take a quick look at the shelves – it takes less time than buying something twice.

Common mistakes

• Planning recipes first and checking the fridge afterwards.
• Leaving the "use first" items for the end of the week.
• Buying a new jar of something because you couldn't see the old one.
• Forgetting allergies when improvising with sauces and mixes.

How GroceryFlow helps

GroceryFlow is an Android app that plans the week around what you already have:

• Add the food you have at home manually, pick a category and adjust the quantity when it changes.
• When the app suggests your 7-day dinner menu, it starts with those items, so they get used first.
• The Shopping List then covers what's still missing for the planned dinners, sorted by store section.
• Don't fancy one of the dinners? Swap that dish without rebuilding the week.

If you also want to keep an eye on spending, read Meal planning on a budget. The app is available in English, Danish and Polish and is currently being tested before public launch.

FAQ – cooking with what you have

What can I make with only basic ingredients?

With rice, pasta or potatoes, eggs, tinned tomatoes, onion and a spice you like, you can make fried rice, tomato pasta, an omelette or a simple soup. The formula above helps you fill the gaps.

How do I use up leftovers without eating the same thing twice?

Change the form: leftover meat can go into wraps or a stir-fry, cooked rice into fried rice, roasted vegetables into a soup or a pasta sauce.

Can I freeze leftovers to use later?

Many cooked dishes can be frozen. Label the container with what it is, and follow food-safety advice for storing and reheating.

Do I need a recipe-finder app?

Not necessarily. A recipe finder helps with one dinner. Planning the week around what you have helps you buy less of what you don't need – with or without an app.
