What to cook with the ingredients you already have: a simple method

To decide what to cook with what you already have, start from the ingredient that will spoil first, add one base (pasta, rice, bread, eggs or potatoes), then pick a simple method (stir-fry, bake, soup, omelette or salad) and season with whatever sauce or spice you have. That four-part formula covers most weeknights without a recipe. When you are out of ideas, an AI recipe tool or app can suggest dishes from your list of ingredients; just check the result against any allergies in your household.

The four-part method (no app needed)

1. Start with what spoils first. Open the fridge and find the vegetable, meat, fish or dairy that needs using today. That is your main ingredient.
2. Add a base. Pasta, rice, noodles, bread, tortillas, potatoes or eggs. Most pantries have at least one.
3. Choose a method that suits the ingredients:
   • Soft vegetables and leftovers: soup, frittata or fried rice.
   • Firm vegetables and meat: tray bake or stir-fry.
   • Salad leaves and cheese: a big salad with bread or a grain.
   • A bit of everything: pasta with a pan sauce.
4. Season with what you have. Soy sauce, tomato paste, mustard, lemon, garlic, chilli, curry powder or herbs. One strong flavour is usually enough.

Write down what worked. After a few weeks you will have a personal list of "fridge dinners" that needs no thinking.

Keep a short pantry list

The method gets faster when you know what you have without opening every cupboard. Keep a list, on paper, in Notes or in an app, of:

• Bases (pasta, rice, flour, tins)
• Sauces and spices you actually use
• What is in the freezer

Update it when you shop and when you run out. This also stops you buying a third jar of something you already have.

When you are out of ideas: AI recipe suggestions

AI tools can take a list of ingredients and suggest dishes. General assistants such as ChatGPT can brainstorm ideas for leftovers and swaps in a chat (Fritz AI roundup). They work well for one-off inspiration. The ideas and lists stay in the conversation, so you have to copy anything you want to keep.

DishBook is built for doing this regularly:

1. Get ideas from what you have. DishBook generates AI recipe ideas from everyday ingredients, and shows a daily "What to cook tonight" pick on Home.
2. Check your pantry list. Keep your pantry in the app next to the recipe ideas and your shopping list.
3. Set an allergen profile. If someone in your home avoids certain foods, add them to the allergen profile so it is part of planning.
4. Cook hands-free. Use voice commands to move through cooking steps and control timers when your hands are messy.
5. Save what worked. Keep favourites and your own recipes in My Recipes, both free for everyone, so good fridge dinners become repeat meals.

DishBook is on iPhone and Android. All Access is a monthly, six-month or yearly subscription. For a side-by-side view, see DishBook vs ChatGPT for meal planning.

Allergies and safety

AI suggestions and allergen profiles are planning aids, not guarantees. Always read ingredient labels yourself, especially for packaged sauces and stock cubes, which often contain common allergens. This is general cooking guidance, not medical or dietary advice.

Turn tonight's dinner into a plan

Once you have a few reliable fridge dinners, plan two or three of them for the week and let the rest be flexible. A short plan with a matching shopping list cuts waste more than a perfect seven-day menu you never follow. Our guide on planning a week of meals with one grocery list shows how.
