The Keurig coffee makers are not known for brewing the best coffee but for brewing coffee with great convenience and ease using K coffee pods.
Since K cups are more expensive than regular coffee grounds, you may be tempted to use ground coffee in Keurig or you might want to use it if you run out of K cups.
I will discuss two methods of using coffee grounds in Keurig, one using old k cups and the other using reusable filters so you can easily make coffee in a Keurig without K-cups.
Keep reading till the end to find out why I am not a big advocate of using ground coffee in Keurig.
Method # 1: How to use ground coffee in Keurig with a reusable K cup
The most efficient way to use ground coffee in Keurig is to invest in a reusable My K cup filter.
Things you need
- Reusable My K cup Filter
- Ground Coffee
- Paper filters (optional)
- Open the lid of the My K Cup filter by sliding it to the Unlock position and pull out the filter basket from the holder.
- Place the paper filter in My K cup if you want. (Optional)
- Pour the coffee grounds into the filter basket. You can add up to two tablespoons of coffee in a reusable K cup. There is a max line inside the filter basket make sure not to overfill it otherwise coffee will leak.
- Now put the filter basket in the holder and close the lid.
- Open the head of your Keurig machine and pull out the K cup holder
- Now place the Reusable My K cup Filter in the place of the K cup holder and close the head of your Keurig machine.
- Select the desired cup size on your Keurig and Enjoy your tasty coffee.
Note that there are two different types of My K Cup filters 1- With only one hole at the top and 2- With five holes at the top. If you have Keurig Supreme or Slim models that have multi-stream technology you have to buy the one with five holes otherwise buy the one with one hole.
If you want to brew an extra smooth cup of coffee you will need a paper filter. Here are some paper filters specially designed for My K cup reusable filters.

Method #2: How to use ground coffee in Keurig without a reusable K cup
Here’s a simple hack for using ground coffee in Keurig without a reusable K-cup.
Things you need
- Ground Coffee
- Aluminum Foil
- Paper Filters
- First, remove the lid of the used k cup and discard the spent coffee grounds from it. Also, remove the paper filter present at the bottom of the K cup.
- Thoroughly rinse and clean the used k cup with water and allow it to dry.
- Take a paper filter and fit it at the bottom of a used k cup. You’ll need a new paper filter since you can’t reuse a paper filter as it will be dirty.
- Now pour coffee grounds into the k cup (Don’t fill it to the top and leave at least 10-15% space empty otherwise your coffee will leak).
- Cut a piece of aluminum foil and wrap it over the k cup as tightly as you can.
- Put this K cup into the machine and press the brew button.
This process will not make the best cup of coffee and you shouldn’t make this a habit (As it can also cause leakage problems in your Keurig machine).
This is merely a hack you can apply if you run out of K cups and don’t feel like going to the market to buy new K cups.

How much coffee do you put in a reusable K cup?
The amount of coffee you put in a Keurig refillable K-cup is two tablespoons (10-15 grams).
The exact amount can vary depending on your personal preference, however, you shouldn’t fill the refillable pods beyond the max line which is around 15-16 grams.
According to the Speciality Coffee Association:
To achieve the Golden Cup Standard, the recommended coffee-to-water ratio is 55 g/L ± 10%.SCA
So according to the golden cup standard, the best coffee-to-water ratio is 1:17. That means 1 gram of coffee for 17 grams of water.
According to that ratio, you should use 14-15 grams of coffee for an 8 oz serving of Keurig coffee to get the best results.
One important thing to note here is that regular Keurig K-cups contain 9-12 grams of coffee and that is definitely not enough for larger Keurig brew sizes. That’s why I always recommend brewing a 6 oz serving size while using regular K cups to get a better and stronger coffee taste.
What’s the best grind size for Keurig
Medium to medium-fine grind size works best with Keurig My K-Cup filters. Too fine coffee grounds can clog or easily escape through my k cup filter, resulting in muddy coffee, and the coarse grounds will result in a watery or under-extracted cup of coffee.
If you really want to brew the best cup of coffee then use whole-bean coffee and grind them to medium settings just before making a cup of coffee.
Otherwise, you can also buy pre-ground coffee. There are plenty of options available in Medium grind size.
Some tips for Cleaning
While using reusable My K cups you will certainly miss the convenience of using k cups.
Put the K cup in the machine brew coffee and throw it into the recycle bin after brewing as simple as it is!
You must clean the reusable K cup after every use. Ideally, you should clean it right after brewing since otherwise, the coffee grounds will get dry and stuck on the filter’s screen making it a lot harder to clean.
When cleaning it after a while, use a soft sponge to remove dried coffee grounds. Avoid using an abrasive material as it will damage the screen.
Pros of Using Ground Coffee in Keurig
Coffee grounds are way more cost-effective than K-cup coffee pods. Using coffee grounds can cut your monthly coffee expenditure to half.
You can use coffee grounds from your favorite brands
K cups are a fine example of producing a ton of unnecessary plastic waste. So, by using a reusable My K cup filter you can brew coffee in a sustainable way.
Cons of using ground coffee in Keurig
The biggest con of using a reusable My K cup filter is it requires a lot of work.
Let me ask you a question why have you bought the Keurig (at a much higher price than a normal coffee maker) in the first place?
For convenience, Right?
Then what’s the point of using coffee grounds and My K cup filters if you have to give up on the convenience?
I see no reason to use coffee grounds in a Keurig machine when you could have bought a Drip machine at a much lower price if you wanted to do that.

Can You Use Instant Coffee In A K Cup?
Yes, you can use instant coffee in a K cup but it’s certainly not recommended. I mean why would you do that?
Instant coffee is specifically made to dissolve completely in water. If you prefer to use instant coffee with your Keurig, the best way is to pour the instant coffee into your cup, place the cup under the Keurig, and run it without inserting any pods.
This way, Keurig will only dispense hot water on top of the instant coffee, so you can simply mix and enjoy
