How to Meal Plan for Beginners: Portions, Shopping and Changing Plans

Start with the evenings you need dinner at home and the time you will have to cook. Pick recipes for those meals, count the portions and check what is already in the kitchen. You can leave the rest of the week open.

Purdue Extension recommends linking your meal plan to the food you have and your shopping list. The example below takes that approach through a few dinners for two, including what to do when plans change.

Check when you will have time to cook

Write down who will be eating and whether the meal will be eaten at home or packed to take along. For a packed lunch, include how it will be kept and transported safely. On an evening when you get home late, choose something you can prepare in the time available.

Choose recipes that suit your equipment, dietary needs and confidence. Read the instructions and check how many portions they make before adding ingredients to the list. Look up any unfamiliar cooking terms now, while you have time.

Next, check the cupboards, refrigerator and freezer. Look at dates and storage history before counting an ingredient or leftover as available. If you are unsure about a leftover, use the storage guide before planning a meal around it.

Plan a few dinners together

Suppose you have chosen a soup recipe that makes four portions and a pasta recipe for two. The example covers three dinners for two people; it is not a complete diet. Use the quantities and cooking instructions from the recipes you actually choose.

Three dinners with different amounts of preparation

Meal	Plan	What needs a decision now?
Sunday	Cook the four-portion soup; serve two portions.	Divide and refrigerate the other two promptly for Monday.
Monday	Reheat the two reserved soup portions for dinner at home.	Keep their original preparation date on the label.
Tuesday	Cook the two-portion pasta recipe.	Buy only the missing recipe quantities; no planned leftovers.

For this example, use US household storage guidance: refrigerate perishables within two hours, or one hour above 90°F (32°C), and keep the refrigerator at 40°F (4°C) or below. Divide hot soup into shallow containers for prompt cooling rather than waiting for a large pot to cool on the counter. These steps follow FDA refrigeration guidance.

Under proper storage, the FoodSafety.gov chart lists three to four refrigerated days for soups and stews containing vegetables or meat. That period applies to those categories, not everything in the refrigerator. Here, the extra soup is already assigned to Monday’s dinner.

Work out what you need to buy

Add up how much of each ingredient your chosen recipes need, then subtract the usable amount you already have. Compare the same form of the ingredient: dry pasta with dry pasta, for example, rather than cooked weight. Check the storage instructions on any opened package.

These assumed quantities show part of the shopping calculation for the pasta dinner. They are an arithmetic example, not a complete recipe or portion-size recommendation.

Worked shopping calculation for three example ingredients

Ingredient	Needed	Usable stock	Still needed
Dry pasta	200 g	80 g	120 g
Canned tomatoes	400 g	0 g	400 g
Frozen vegetables	300 g	100 g	200 g

If the smallest pasta package available is 500 g, you will buy one package to cover the missing 120 g. Using that amount leaves 380 g in the new package. Note what remains for another meal; you do not need to cook the whole package.

Add the soup ingredients and any other planned meals to the same list, combining shared ingredients on one line. If several recipes share ingredients, the recipe-to-list worksheet shows how to keep forms, units and package remainders separate. If the resulting list exceeds the amount available, compare cost per usable portion before replacing an ingredient. If you change a recipe, update the list and check its cooking method, yield and storage instructions too.

When Monday dinner gets cancelled

If you already know on Sunday that Monday’s soup dinner will not happen, freeze the extra portions promptly and keep both the preparation and freezing dates. If plans change later, check how long the soup has been stored and how it was handled before deciding what to do. Freezing will not rescue food that has been kept unsafely.

Allow time to thaw and cook a frozen portion safely when you put it back on the menu. Check the leftover guide for reheating temperatures.

Keep the ingredients and instructions for a backup meal in mind. You can leave it unprepared if the original plan works, so you do not end up with another batch of leftovers to use.

Use the meal-planning sheet
