Boil some water in a saucepan, while it’s heating we can wash, peel and cut the potatoes roughly. Some people don’t like to remove the skin, but it will help produce a fluffier and creamier mashed potato. Put the potatoes into the boiling water along with the garlic and some extra salt for flavor. Boil them for 12-15 minutes, an easy way to check they are done is to pierce them with a fork. If the fork enters easily they’re ready! Remove the potatoes from the water and drain, keep tossing to help dry them out further. The less moisture the better for our mashed potatoes' consistency!
Transfer them to a bowl and mash them using a potato masher, if you don’t have one to hand a fork can also work.
Melt the butter into a saucepan, then add the milk and oil. Keep stirring until everything thickens up.
Once you are happy with it, turn off the heat and transfer the potatoes you just mashed back to the pan and stir everything up until it’s nice, silky, and smooth.
Season with salt and pepper and you’re done! Now we can move on to the Cajun Gravy.
Using a clean skillet, combine the diced onions, celery, red bell peppers, and add some salt. Saute them for 2-3 minutes and remove them from the skillet.
To the same pan, we add the butter, flour, and bacon grease. Let it cook until it turns to a browny-peanutty kind of look.
Re-add the vegetables to the pan and cook them for another 2-3 minutes. While they are cooking we can add all the delicious spices to it, this includes paprika, cayenne pepper, garlic powder, celery salt, white pepper, and thyme.
Keep it boiling until everything has thickened and then add the veal stock and Worcestershire sauce.Pour this over the mashed potatoes and it’s ready to enjoy!
