How it works
From a fridge of odds and ends to a finished dinner — in three steps.
Step 1
Tell us what's left over
Type the cooked chicken, roasted vegetables, or extra rice sitting in your fridge — or snap a photo or say them out loud instead.
Step 2
The expiring thing leads
Whatever you need to use up first is what recipes get matched around — it's the star, not an optional extra.
Step 3
Dinner, not another container
Get a personalized recipe with a full ingredient list, clear step-by-step instructions, and a realistic cooking time.
Why it's different
No dish is named “half a container of rice with some roast chicken.” That's exactly why ingredient matching wins.
Recipe sites search by dish name
And no dish is named after your leftovers. Cook Compass matches by ingredient, so the food you'd otherwise throw away becomes the starting point.
Built for food with a clock on it
Leftovers don't wait. Whatever expires first is the priority your recipes are built around — tonight, not someday.
Fast by default
Leftover night is a tired weeknight. Suggestions here default to 15-minute recipes, so dinner happens before the guilt does.

FAQ
Common questions about cooking with leftovers.
What can I make with leftover chicken?
Add chicken along with whatever else you have — vegetables, rice, tortillas, cheese — and Cook Compass matches real recipes built on those ingredients, from soups and stir-fries to salads and grain bowls. The more you add, the better the match.
How long do leftovers last in the fridge?
USDA guidance: eat cooked leftovers within 3 to 4 days, or freeze them. Reheat to 165°F (74°C). When in doubt, throw it out — no recipe is worth a risk. See the leftover clock above for the full picture.
Can it prioritize the ingredient that expires first?
Yes — the ingredients you add are exactly what recipes are matched around. If finishing that half container of cooked rice is the priority, put it on your list and every suggestion will be built on it.
Is the leftover recipe generator free?
Generating a recipe costs 10 credits, and the Free plan gives you 30 credits every day — enough for about three recipes daily. Photo ingredient recognition never uses credits.
Should I freeze leftovers or cook them into something new?
Both beat the bin. If you can cook within the USDA 3–4 day window, turn them into tonight's dinner — that's the fastest win. If not, freeze portions now and they'll be ready for a future meal. Cooked rice, soups, and stews all freeze well.
