How to Crack Peppercorns

Cracking peppercorns is fairly easy to do.

To do it, put them on a clean work surface like a cutting board.

Then press them firmly with a skillet or even a sturdy drinking glass.

You don’t want to pulverize them- just gently break them.

Are cracked peppercorns spicy?

The more finely you grind peppercorns the spicier they become.

This is why you just want to crack them and not grind them or really crush them during the process of cracking them.

Cracked peppercorns give you a ton of cozy warm flavors without a lot of heat.

How to Make

This peppercorn chicken is so easy thanks to the slow cooker!

To make it, whisk the onion powder, garlic, whole and cracked peppercorns, Worcestershire, mustard, oregano, and broth together in the bowl of your slow cooker until combined.

Then add the mushrooms and cubed cream cheese to the liquid.

Lay the chicken on top of the mushrooms and cubed cream cheese in the liquid.

Put the cover on the slow cooker and cook on low heat for 5-6 hours.

When there’s 30 minutes of cook time left, whisk together the cornstarch and water to form a slurry then stir it into the liquid in the crockpot.

Cover and turn the heat up to high for the remaining 30 minutes.

Stir in the Parmesan cheese.

Serve and enjoy!
