What to Eat Tonight? Cooking with What's in Your Fridge

It's 7 pm, the fridge door is open, and nothing comes to mind. There are three eggs, a piece of cheese, a slightly soft zucchini and half a bag of pasta. Ordering takeout or running to the store is tempting. Yet with a little method, those leftovers are almost always enough for a real meal. Here's how to plan meals around what you already have, cut food waste, and find an idea in seconds with our What to Eat? tool.

Why "what's for dinner?" is so exhausting

Deciding on a meal isn't hard in itself. What wears you down is the repetition: twice a day, every day, often at the end of the day when your energy is at its lowest. This is known as decision fatigue: the more choices you make in a row, the more tempting the easiest option becomes, and it isn't always the cheapest or the healthiest.

The good news is that you can flip the problem around. Instead of asking "what do I feel like?", an endlessly open question, start from what's available: "what can I make with this?". The choice shrinks to a handful of concrete options, and the decision becomes much easier.

Start from the fridge, not the recipe

Most cookbooks work the other way around: you pick a recipe, then buy what it calls for. For everyday cooking, a "fridge first" approach works better:

1. Take stock: glance at the fridge, the pantry and the freezer. Spot what needs to be used up first (vegetables going soft, an open carton of cream, a date coming up).
2. Pick a star ingredient: it sets the tone for the dish. Eggs, leftover chicken, potatoes, a can of chickpeas.
3. Add a base: pasta, rice, bread, pie crust, couscous, lentils. Pantry staples turn almost nothing into a full meal.
4. Fill in with what's left: a vegetable, a cheese, a herb, a spice. That's often where the dish gets its character.

That's exactly how the What to Eat? tool works: you tick what you have, and it shows you the recipes you can make, starting with the ones you can cook right now, then the ones missing only one or two ingredients.

The basic pantry: what's worth always having

Cooking with what you have assumes you have a few supplies. You don't need a restaurant-sized pantry: a handful of long-lasting products is enough to get you out of most situations.

• Starches: pasta, rice, flour, couscous, red lentils.
• Canned goods: diced tomatoes, chickpeas, tuna, coconut milk, corn.
• Fresh items that keep: eggs, butter, a hard cheese (parmesan, aged cheddar), onions, garlic, potatoes.
• Seasonings: oil, vinegar, mustard, soy sauce, bouillon cubes, curry powder, cumin, dried herbs.
• Freezer: spinach, peas, mixed vegetables, puff pastry.

With just eggs, flour and milk, you already have crêpes or pancakes. Add potatoes and an onion: a hearty potato omelette. Pasta, a can of tomatoes and some garlic: a pasta dish in fifteen minutes.

In the tool, salt, pepper, oil and water are treated as always available: no need to tick them.

"Clean out the fridge" recipes that save a weeknight

Some recipes are true all-rounders: they accept almost any leftover and forgive approximations. They're worth knowing by heart.

Omelette, frittata and shakshuka

Eggs are a leftover's best friend. A few sautéed vegetables, some ham, grated cheese: anything goes. Shakshuka, eggs poached in a spiced tomato sauce, turns a simple can of tomatoes into a real meal.

Quiche and savory tarts

A pie crust, three eggs, cream or milk, and whatever filling is at hand: leeks, bacon, zucchini, tuna, goat cheese. Add a green salad on the side and dinner is done.

Gratins

Potatoes, zucchini, yesterday's pasta, cauliflower: cover with cream or white sauce, sprinkle with cheese, and let the oven do the rest. It's also the best way to use up odds and ends of cheese.

Soups

Tired-looking vegetables are perfect for soup: an onion, water or stock, twenty minutes of simmering and a quick blend. A spoonful of cream or a little melted cheese, and even kids ask for more.

Fried rice and stir-fries

Day-old cooked rice is ideal for egg fried rice: drier, it fries without sticking. An egg, a few peas, leftover ham or chicken, a splash of soy sauce.

French toast and leftover desserts

Stale bread becomes French toast; overripe bananas, banana bread; bruised apples, applesauce. Nothing goes to waste.

Less waste, more savings

Cooking what you already have is also the simplest way to reduce food waste. A lot of the food thrown out at home goes because it was forgotten at the back of the fridge, or because nobody knew what to do with it. A few habits make a big difference:

• Read date labels correctly: a "use by" date on perishable foods such as meat or fish is about safety and should be respected. "Best before" or "best if used by" dates are about quality: dry pasta, rice, crackers or canned goods are usually still fine to eat afterwards.
• First in, first out: put the items to finish first at the front, and newly bought ones at the back.
• Keep an "eat me first" shelf: one spot in the fridge for leftovers and opened products, to check before every meal.
• Freeze before it's too late: bread, meat, sauces, and chopped fresh herbs in a little oil all freeze very well.
• Shop with a list: you buy fewer unnecessary items, so you throw away less.

For your budget, the effect is twofold: you get full value from what you've already paid for, and you skip the last-minute grocery run, where you rarely walk out with just one item.

How to use the What to Eat? tool

Our What to Eat? tool offers around fifty simple, family-friendly recipes, from a cheese omelette to chili con carne, red lentil dal or French yogurt cake. It works in four steps:

1. Tick your ingredients in the list, or type their name in the search box and press Enter.
2. Browse the suggestions: recipes you can make right now come first, then those missing one or two ingredients.
3. Narrow things down with the filters: type of dish (mains, starters, desserts, breakfast), preparation time (15 min, 30 min, 1 hour), vegetarian recipes, number of missing ingredients allowed.
4. Open a recipe to see the quantities and steps, adjust the number of servings, and copy the shopping list of missing ingredients in one click.

Optional ingredients, such as toppings or sides, never block a recipe: only the essential ingredients count. Your selection is stored only in your browser so you'll find it again on your next visit; nothing is sent to a server.

Swaps that unlock a recipe

Missing an ingredient? That's not necessarily a deal-breaker. Many are easy to replace:

• Cream ↔ milk (lighter) or plain yogurt, as long as it isn't boiled hard;
• Grated cheese ↔ cheddar, Swiss, mozzarella or any good melting cheese;
• Bacon ↔ diced ham, chorizo, or mushrooms for a vegetarian version;
• Butter ↔ neutral oil in most cakes, using a little less;
• Onion ↔ shallot or the white part of a leek;
• Fresh herbs ↔ dried herbs, using roughly a third of the amount.

Trust your taste: an everyday recipe is a starting point, not a rulebook.

In short

To stop staring blankly into the fridge, just flip the question: start from what you have rather than what you'd like. A well-chosen basic pantry, a few all-purpose recipes and a couple of anti-waste habits are enough to cook nearly every night without last-minute shopping. And when inspiration really runs dry, tick your ingredients in What to Eat?: the answer appears in seconds.
