Your results will appear here.
Enter your values and press Calculate.
Enter the number of servings you need, from 1 to 200, and the calculator works out your ratatouille batch at once. It uses a fixed ratatouille serving size of 250 grams per person, so 20 servings gives 5000 grams of ratatouille, and it allows 200 grams of vegetables per person, so the same 20 servings needs 4000 grams of vegetables. That simple rule answers how much ratatouille per person to plan, and it scales cleanly whether you are cooking for a small table or planning ratatouille for a crowd. Use the result to shop, to choose a ratatouille large pot, and to plan a ratatouille batch recipe without guessing. If you change the servings, both totals update at once, so you can test a side dish portion, a main course portion, or ratatouille for 50 servings in seconds.
body: "This ratatouille batch calculator uses one clear rule, so you never have to guess a quantity. Each serving is planned as 250 grams of finished ratatouille, and 200 grams of vegetables per person goes into that serving. Multiply servings by 250 to get total ratatouille grams, and multiply servings by 200 to get total vegetable grams. For 10 servings, that is 2500 grams of ratatouille and 2000 grams of vegetables. For 50 servings, it is 12500 grams of ratatouille and 10000 grams of vegetables. The formula stays the same at every size, which makes shopping, chopping, and pot planning simple. Use the vegetable total for fresh produce shopping, and use the ratatouille total to judge how much finished dish you will serve."
body: "Enter only the number of servings you plan to feed, then read the two results. The first result is the total ratatouille you need, in grams. The second result is the total vegetables you need, also in grams. There are no extra settings to adjust, and no hidden steps. If your guest list changes, change the servings number and check the new totals before you shop. This is useful for a family dinner, a party, and ratatouille crowd cooking for a larger gathering. It also helps when you want to test a smaller trial batch first, then scale up once you know the dish suits your guests."
body: "Ratatouille vegetables per person are set at 200 grams in this calculator, which covers the classic mix of eggplant, zucchini, peppers, tomatoes, onion, and garlic. Fresh herbs, olive oil, salt, and seasoning sit outside that vegetable weight, so buy those as usual for your own recipe. When you shop, split the vegetable total across the vegetables you plan to use, keeping the mix balanced rather than loading it with one vegetable only. Uniform chopping helps the vegetables cook evenly, and it also helps the finished stew look neat. If you add mushrooms, beans, or extra peppers, keep the total vegetable weight close to the calculator result so the texture stays right."
body: "Ratatouille pot size matters as much as the ingredient total. For ratatouille crowd cooking, use a large pot or Dutch oven, and cook in batches if the vegetables would otherwise be crowded. Crowded vegetables steam instead of browning, and they release water that can make the stew thin. To scale ratatouille recipe quantities safely, keep the servings rule the same and split a very large batch across two pots rather than forcing it into one small pot. Brown the vegetables in batches, then combine them for simmering. That method works for a small family batch and for ratatouille for 50 servings, with only the number of batches changing."
body: "For ratatouille make ahead cooking, cook the batch a day early when you can, because the flavours meld as it rests. Cool it fully, then store it in an airtight container in the refrigerator for 3 to 4 days, following the storage guidance used by the competitor recipe pages. To freeze ratatouille, cool it completely first, then pack it into freezer-safe containers or bags for 2 to 3 months. Thaw frozen ratatouille in the refrigerator overnight, then reheat it gently on the stovetop, stirring often, until it is heated through. Leftover ratatouille also works spooned over grains, folded into an omelet, or served with crusty bread."
body: "This ratatouille French vegetable stew comes from Provence, and it works in many roles. For ratatouille side dish servings, pair it with grilled meat, fish, or tofu, and serve it with crusty bread to catch the juices. For ratatouille main course servings, serve it over rice, polenta, quinoa, or pasta, or add beans for a fuller vegan plate. The classic dish is naturally vegetarian, vegan, dairy free, and gluten free when no cheese or bread topping is added. Try pistou or fresh basil on top, a splash of balsamic vinegar at the end, or a pinch of red pepper flakes for warmth. Keep the calculator totals the same, and change only the accompaniment."
Plan 250 grams of ratatouille per person, which is the ratatouille serving size used by this calculator. That gives ratatouille serving grams of 2500 grams for 10 servings, 5000 grams for 20 servings, and 12500 grams for ratatouille for 50 servings. If ratatouille is only one of several side dishes, some hosts plan a little less, but 250 grams is a safe main serving amount.
Allow 200 grams of vegetables per person. That is the ratatouille vegetables per person figure in the formula, so 20 servings needs 4000 grams of vegetables in total. Split that total across eggplant, zucchini, peppers, tomatoes, onion, and garlic, and buy herbs, oil, and seasoning separately.
To scale ratatouille recipe amounts, multiply your servings by 250 grams for ratatouille and by 200 grams for vegetables. Do not change the per person amounts as the batch grows. For very large groups, cook the vegetables in batches and use a larger pot, or split the batch across two pots, so the vegetables brown properly instead of steaming.
Use the largest heavy pot or Dutch oven you have for a crowd batch, and cook in batches when the pot would be overcrowded. A large pot spreads heat evenly and gives the liquid room to reduce. If the batch still looks crowded after the first vegetables go in, brown the rest separately and combine everything for the final simmer.
Yes. Canned diced or crushed tomatoes work well, especially outside tomato season. Drain off excess liquid if the canned tomatoes look very watery, so the finished ratatouille does not turn thin. Fresh tomatoes give a brighter flavour, but canned tomatoes give a consistent result for a large batch.
Peeling eggplant is often recommended because the skin can taste bitter, while peeling zucchini is optional. Leaving zucchini skin on adds texture and colour. Whichever you choose, cut the pieces to a similar size so the eggplant, zucchini, and peppers cook at the same rate.
Yes. Bell peppers in different colours, mushrooms, and beans are common additions. Add them in the same style as the main vegetables, and keep the total vegetable weight close to the calculator result. Adjust cooking time if a new vegetable is much firmer or softer than the classic mix.
Do not overcrowd the pot, brown the vegetables in batches, and simmer uncovered at the end if the stew still looks watery. Cut eggplant a little larger than zucchini, because eggplant softens more. Stop cooking when the vegetables are tender but still hold their shape, and remember the stew thickens a little as it cools.
Yes, you can layer the vegetables in a slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, following the crowd recipe guidance. Store leftovers in an airtight container in the refrigerator for 3 to 4 days, or freeze ratatouille for 2 to 3 months. Thaw in the refrigerator overnight and reheat gently on the stovetop.
Classic ratatouille is vegetarian and vegan, dairy free, and gluten free, provided you use a dairy free fat and no cheese topping. Calorie figures vary by recipe and oil amount, and published nutrition pages give different values for a 250 gram serving, so this calculator reports grams only and does not claim a fixed calorie total. Treat any calorie figure as an estimate, not professional nutrition advice.
