Method #2: How to use ground coffee in Keurig without a reusable K cup (Reusing Used K cups)

Here’s a simple hack for using ground coffee in Keurig in case you run out of K-cup coffee pods.

Reusing k cups with coffee grounds

Things you need

  • Keurig coffee maker
  • Reusable My K cup Filter
  • Ground Coffee
  • Aluminum Foil
  • Paper Filters

Instructions

  1. First, remove the lid of the used k cup and discard the spent coffee grounds from it (Here are some creative ways to reuse coffee grounds). Also, remove the paper filter present at the bottom of the K cup.
  2. Thoroughly rinse and clean the used k cup with water and allow it dry.
  3. 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.
  4. 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).
  5. Cut a piece of aluminum foil and wrap it over the k cup as tightly as you can.
  6. 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 market for buying new k cups.

What’s the best grind size for Keurig

Medium or medium fine Grind size is best for use in 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.

Here’s a detailed guide on different coffee grind sizes

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 waste 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.

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 want to do that.

FAQs

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 designed to dissolve completely in water. If you want to use instant coffee in Keurig the better way is to pour instant coffee into your cup, place the cup under Keurig, and run Keurig without inserting any pods so Keurig only dispenses hot water on top of the instant coffee.

Can You Use Keurig Without A K Cup?

No, Keurig coffee makers are only designed to brew coffee using K-cup coffee pods. If you don’t have any K-cup coffee pods you can use reuse old K-cup coffee pods as the trick mentioned in this article.
Otherwise, there is no way of using coffee grounds directly in the Keurig machine. You can run it without inserting a K-cup coffee pod if you just need hot water from Keurig.
