The knish derives from Eastern European, Jewish homes. The word is a Yiddish one. Instead of making the dough from scratch, this recipe uses puff pastry, making this quite a simple recipe to follow. You can even used packaged or re-hydrated mashed potatoes if you'd like. Eat this as a snack, or with a protein (fish, chicken, beans), and a non-starchy vegetable (spinach, broccoli, etc.).

Best eaten warm, by re-heating in a toaster oven or oven. These may be frozen for up to 6 months, and defrosted in the oven.

These would pair nicely with our Stuffed Cabbage, and/or our creamy beat salad.

This recipe is adapted from a recipe by Two Cooks In The Kitchen.

Step 4

Step 6
Unroll the puff pastry sheets and use your fingertips to thin them out a bit.
Step 7

Step 8

Notes

We don't peel the potatoes in this recipe. Leaving the skins on adds additional fiber, which is healthy for our digestion and our gut.

If you use onion and garlic powder instead of onions, this dish still comes out tasting delicious. The quantity is not listed, so add about 1/2 teaspoon of onion and/or garlic powder to the mashed potatoes, taste, and add more as needed.
