The short answer
Plan first. Combine ingredients second.
Choose the recipes you will really cook, set the number of portions, copy every ingredient with its quantity, combine compatible duplicates, group the result by grocery category, then check the kitchen before shopping. Keep the final list connected to the plan so a changed dinner does not leave behind irrelevant ingredients.
The most common mistake is starting with seven attractive recipes. Start with the calendar instead. A takeaway night, leftovers, or dinner out should remove a recipe before it adds anything to the list.
The method
Five steps from recipes to a grocery list.
Choose only the recipes the week needs.
Mark dinners that are already covered by plans, leftovers, or takeout. Then choose enough recipes for the remaining nights. If one batch covers two dinners, count it once. This keeps the shopping list attached to a realistic cooking workload.
Useful check
Can you point to the night when each recipe will be cooked or reheated? If not, it probably does not belong on this week’s list.
Scale every recipe before copying ingredients.
A recipe written for four does not make a correct list for two, six, or a batch that must cover tomorrow as well. Set the required portions first, then scale every quantity. Keep optional toppings separate so they can be removed without changing the base meal.
Useful check
Count both people and planned leftovers. Four people eating tonight plus two lunch portions means shopping for six, not four.
Combine duplicates only when they are genuinely compatible.
Two recipes may both need onions, garlic, rice, or stock. Add compatible amounts into one line. Do not merge ingredients just because their names look similar: fresh tomatoes and canned tomatoes, or chopped herbs and whole garnish, may serve different jobs.
Useful check
Normalize units before adding. Convert grams to grams or cups to cups, and keep “one bunch” separate when the other recipe specifies a measured weight.
Group the list the way you move through the shop.
Put produce, meat or alternatives, chilled items, pantry goods, and bakery items together. A categorized list reduces backtracking and makes duplicate lines easier to spot. Keep the ingredient name first and the total quantity beside it.
Useful check
Read each category once before leaving it. That is easier than scanning three recipes repeatedly in every aisle.
Check the kitchen, then keep the list tied to the plan.
Cross off what you already own only after checking the cupboard, fridge, and freezer. If a meal changes later, remove its ingredients and add the replacement. A grocery list is trustworthy only when it still describes the current plan.
Useful check
Keep checked items visible until the shop is finished. It prevents accidental re-adding and gives you a record of what is already in the basket.
Worked example
Three recipes do not need three separate lists.
Imagine the week includes Spicy Chicken Burgers, Coconut Chickpea Curry, and Sticky Garlic Beef.
Three ingredient lists
Each recipe repeats staples such as garlic, onions, rice, oil, or seasonings.
Correct weekly quantities
Portions reflect the people eating and any meals intended to cover another night.
One route through the shop
Produce appears together, proteins together, and pantry ingredients together.
The final list should still preserve meaningful differences. Jasmine rice can combine across two meals; burger buns should remain their own bakery line. The goal is not the shortest possible list. It is a list you can trust without reopening every recipe.
Manual list or app?
Use the method that matches your recipe source.
A spreadsheet or notes app works when the week is small and you enjoy maintaining it. A recipe-importing app is a better fit if your recipes come from social posts, websites, or a personal cookbook.
Where PrepWeek fits
PrepWeek is for choosing from a curated recipe catalog, connecting those recipes to dinner nights, scaling portions, and producing one categorized grocery list. It does not currently import personal recipes.

Useful answers before you start.
Can PrepWeek turn recipes into a grocery list?
Yes. PrepWeek builds one categorized grocery list from the recipes and portions in your selected dinner plan.
Can I import my own recipes into PrepWeek?
Not currently. PrepWeek uses its curated recipe catalog. Choose a recipe-importing app if your main goal is converting personal or social recipes into a list.
Should pantry staples stay on the grocery list?
Keep them until you confirm what is already at home. Removing staples from memory is how small missing ingredients derail a planned meal.
What happens when two recipes use the same ingredient?
Compatible quantities should be combined into one practical grocery line. Check units and ingredient forms before adding amounts together.
