How to Cook Buckwheat: Cooking Time and Water Ratio
Roasted buckwheat groats (kasha) are simmered for 15-20 minutes after the water boils, covered, over low heat, then taken off the heat and left to rest for 10 minutes. Use twice as much water as groats by volume: 2 cups of water and 1/2 tsp of salt for 1 cup of buckwheat. For softer buckwheat, use 2.5 cups. Buckwheat grits take 15-20 minutes, green buckwheat 10-15 minutes plus 15-20 minutes covered, boil-in-bag buckwheat 10-15 minutes.
How long to cook buckwheat: time and ratio table
Start timing when the water boils, then turn the heat down to the lowest setting and cover the pot tightly. Ratios are by volume: measure the groats and the water with the same cup. A 250 ml (1 cup) measure holds about 210 g (7.4 oz) of buckwheat, and cooked buckwheat weighs roughly three times as much as dry.
| What you cook | Cooking time and water per cup |
|---|---|
| Roasted groats, fluffy Do not stir while cooking | 15-20 min + 10 min covered water: 2 cups |
| Roasted groats, soft Good for kids | 20-25 min + 10 min covered water: 2.5 cups |
| Thick porridge For patties and casseroles | 25-30 min water: 3-3.5 cups |
| Buckwheat grits (cracked) Makes a soft porridge | 15-20 min water: 2.5-3 cups |
| Green buckwheat Rinse until the water runs clear | 10-15 min + 15-20 min covered water: 2 cups |
| Boil-in-bag buckwheat Check the package | 10-15 min 1-1.5 litres per bag |
| With milk Cook in water for 10 min first | 20-25 min water: 1 cup water and 1-1.5 cups milk |
| Multicooker Buckwheat or Grain mode | 25-40 min by program water: 2 measuring cups |
| Microwave Stir every 5 min | 12-15 min at 600-800 W water: 2 cups |
| Thermos, no boiling Wide-mouth thermos | 1-2 h water: 2 cups boiling water |
| In soup Buckwheat soup with meatballs | last 15-20 min of cooking 1/2 cup per 2.5-3 litres of soup |
Exact time depends on the groats and the stove. Buckwheat is done when the water is fully absorbed, small steam holes appear on the surface, and the grains are tender but whole.
How to cook fluffy buckwheat in a pot: step by step
1. Measure the groats and water
For 1 cup of buckwheat, take 2 cups of water and 1/2 tsp of salt. If you prefer weighing, use about 240 ml of water per 100 g of groats. One cup of dry buckwheat makes 3-4 side servings: allow 50-70 g (1.8-2.5 oz) of dry groats per person.
2. Sort and rinse
Spread the groats on a light plate and pick out dark grains, husks and any small stones. Then rinse the buckwheat in a bowl or sieve with cold water 2-3 times, until the water is almost clear, to wash off dust and fine crumbs. Packaged premium groats rarely need sorting, but rinsing is still worth it.
3. Toast the groats if you like
Spread the rinsed buckwheat in a dry skillet and heat it for 3-5 minutes over medium heat, stirring, until the grains are dry and smell nutty. Toasting boosts the aroma and helps the grains stay separate. This step is optional: brown roasted groats turn out fluffy without it.
4. Bring to a boil
Transfer the buckwheat to a heavy-bottomed pot, add the water and salt, and bring to a boil over high heat. You can also do it the other way round and pour the groats into salted water that is already boiling. Either way, the time counts from the boil. Skim off any husks and foam that float up.
5. Simmer covered over low heat
Turn the heat down to the lowest setting, cover the pot tightly and cook roasted groats for 15-20 minutes. Do not stir: a spoon breaks the softened grains and the side dish turns gluey. To check the water, gently push the groats aside near the wall of the pot: if there is still liquid at the bottom, cook for 2-3 more minutes.
6. Let the buckwheat rest
Take the pot off the heat and leave it covered for 10 minutes; you can also wrap it in a towel. During this time the steam spreads through the grains and the remaining moisture is absorbed. Then add a knob of butter and fluff the buckwheat with a fork.
Water ratios: fluffy, soft and thick buckwheat
The texture of buckwheat depends mostly on the amount of water. Measure the groats and water with the same cup and keep the heat low.
- Fluffy side dish: 1 cup of groats to 2 cups of water, 15-20 minutes plus 10 minutes covered.
- Soft, for kids and light meals: 1 cup to 2.5 cups of water, 20-25 minutes plus 10 minutes covered.
- Thick porridge for patties, casseroles and buckwheat fritters: 1 cup to 3-3.5 cups of water, 25-30 minutes.
- Porridge with milk: 1 cup of groats, 1 cup of water and 1-1.5 cups of milk.
If the buckwheat comes out a little dry, add 2-3 tbsp of boiling water and keep it covered for 5 more minutes. Excess water can be cooked off uncovered over low heat in 2-3 minutes.
Roasted groats, grits and green buckwheat: how long to cook each
Stores sell three kinds of buckwheat, and each one cooks differently.
Roasted groats (kasha)
Whole hulled kernels. Brown groats are steamed and dried at the factory, so they cook quickly and keep their shape. They need 15-20 minutes and are the main choice for a fluffy side dish.
Buckwheat grits
Cracked kernels, that is, small pieces of the groats. Grits release starch faster and make a soft, slightly thick porridge, so they are used for kids, patties and casseroles. One cup of grits needs 2.5-3 cups of water and 15-20 minutes of cooking.
Green buckwheat
Unroasted, unsteamed groats of a pale green or beige colour. They have a mild grassy flavour and release a slimy film when soaked and cooked, so they are rinsed especially well.
- Without soaking: 1 cup of groats to 2 cups of water, 10-15 minutes over low heat, then 15-20 minutes covered off the heat.
- With soaking: cover the groats with cold water for 6-8 hours, rinse off the slime, add fresh water just to the level of the groats and cook for 5-10 minutes until tender.
- Long cooking turns green buckwheat into mush, so it is usually finished covered off the heat rather than on the stove.
How long to cook boil-in-bag buckwheat
A small portion of groats in plenty of boiling water cooks faster than in a pot: boil-in-bag buckwheat needs 10-15 minutes. The exact time is printed on the package.
- Bring 1-1.5 litres of water per bag to a boil and add salt: about 1 tsp per litre.
- Drop the bag into the boiling water so that it is fully covered. There is no need to pierce the bag: the water gets in through the holes.
- Cook for 10-15 minutes over medium heat.
- Lift the bag out by its loop with a fork, let the water drain, cut the bag open and tip the buckwheat onto a plate.
In a bag the groats cook in a lot of water, so they come out slightly moister than in a pot. Add butter right after cooking.
How to cook buckwheat in a multicooker, microwave or thermos
In a multicooker
- Put the rinsed buckwheat into the bowl and add water: 1 measuring cup of groats to 2 cups of water, then salt.
- Select the Buckwheat, Grain or Rice mode. The program sets the time, usually 25-40 minutes depending on the model.
- After the signal, leave the buckwheat on Keep Warm for 10 more minutes, then add butter and stir.
In a microwave
- Use a deep microwave-safe dish: the water rises as it boils.
- Pour 2 cups of hot water over 1 cup of buckwheat, add salt and cover loosely.
- Cook for 12-15 minutes at 600-800 W, stirring every 5 minutes because a microwave heats unevenly, then leave covered for 5 more minutes.
In a thermos, without boiling
Put the buckwheat into a wide-mouth thermos, pour in boiling water at a 1:2 ratio, add salt and close it for 1-2 hours. The groats can also be steeped in a pot: pour boiling water over them, cover, wrap the pot in a towel and leave for 1-2 hours. This method is handy for trips and work lunches.
How to cook buckwheat with milk
In milk alone, buckwheat takes a long time to cook and easily burns, so it is first cooked in water. Pour 1 cup of water over 1 cup of groats, add salt and cook covered for 10 minutes, until the water is absorbed. Add 1-1.5 cups of hot milk and 1-2 tsp of sugar and simmer over the lowest heat for 10-15 more minutes. Finish the porridge with butter.
How long to cook buckwheat in soup
Rinsed raw buckwheat goes into the soup 15-20 minutes before the end of cooking, together with the potatoes or right after them. For 2.5-3 litres of soup, 1/2 cup of groats is enough: buckwheat swells a lot and keeps soaking up the broth while the soup cools. This is how buckwheat soup with meatballs and buckwheat soup with mushrooms are made.
Common mistakes
- Stirring buckwheat while it cooks in a pot. The grains break, starch comes out, and the side dish turns gluey. Fluff cooked groats with a fork instead.
- Lifting the lid. Steam escapes and the top layer of grains stays hard. Check the water only at the end of cooking.
- Cooking over high heat. The water boils away before the grains soften, and the bottom burns. After the boil, keep the heat at the minimum.
- Eyeballing the water. Fluffy buckwheat needs 1:2, soft buckwheat 1:2.5. Measure the groats and the water with the same cup.
- Cooking old groats. Buckwheat stored for a long time in a warm or bright place can taste bitter. Keep it in a closed jar somewhere cool and dry.
- Leaving the pot on the stove overnight. At room temperature bacteria multiply quickly in cooked food. Cool the buckwheat and refrigerate it within 2 hours.
How to store cooked buckwheat
- Cool the buckwheat and put it in the fridge no later than 2 hours after cooking.
- In a closed container at 0-4 °C (32-40 °F) it keeps for 2-3 days.
- To freeze, pack the buckwheat in portions: it keeps in the freezer for up to 1 month.
- Reheat it in a skillet with a spoonful of water or covered in the microwave until it is hot all the way through.

❓ Frequently asked questions
How long do you cook buckwheat after the water boils?
Roasted groats simmer for 15-20 minutes over low heat, covered, then rest off the heat for 10 minutes. Buckwheat grits take 15-20 minutes, green buckwheat 10-15 minutes plus 15-20 minutes covered, boil-in-bag buckwheat 10-15 minutes.
What is the buckwheat to water ratio?
For fluffy buckwheat, 1:2 by volume: 1 cup of groats to 2 cups of water. For soft buckwheat 1:2.5, for thick porridge 1:3-3.5. By weight, a fluffy side dish needs about 240 ml of water per 100 g of groats.
Do you need to rinse buckwheat?
Yes, 2-3 times in cold water to remove dust, fine crumbs and husks. You can then dry the rinsed groats in a dry skillet for a stronger aroma.
When should you salt buckwheat?
Right away, together with the water, so the salt spreads evenly through the grains. A guide: 1/2 tsp per cup of groats. Butter goes in at the end, after the buckwheat has rested.
Should buckwheat go into cold or boiling water?
Both work. Boiling water is more convenient because the timing is easier. If you start with cold water, count the time from the boil; the result is almost the same.
Why does buckwheat turn into mush?
Usually because of too much water, stirring during cooking or high heat. Measure the water with a cup (1:2), do not stir the groats and keep the heat at the minimum. Grits always make a softer porridge than whole groats.
How long do you cook green buckwheat?
Without soaking, 10-15 minutes over low heat and 15-20 minutes covered off the heat, with water at 1:2. After soaking for 6-8 hours, the groats are rinsed of slime and cooked for 5-10 minutes.
How long do you cook boil-in-bag buckwheat?
10-15 minutes in boiling salted water, 1-1.5 litres per bag. The time depends on the brand and is printed on the package.
How much buckwheat per person?
For a side dish, 50-70 g (1.8-2.5 oz) of dry groats, roughly a third of a cup. After cooking, the serving weighs 150-200 g, because buckwheat roughly triples in weight.
How many calories are in cooked buckwheat?
Dry buckwheat has 346 kcal per 100 g (USDA data). Buckwheat cooked in water without butter has 92-115 kcal per 100 g: the more water the groats absorb, the fewer calories in every 100 g. Portions are easy to count in the buckwheat calorie guide.
