Gluten-Free Potato Knish Casserole 🥔✨

Yes! You can absolutely make a delicious gluten-free version of potato knish casserole by swapping out traditional dough for a GF crust or skipping it entirely for a layered, crustless casserole (like a knish-inspired kugel!). Here’s how:

Gluten-Free Potato Knish Casserole (Two Ways)

Option 1: GF Pie Crust Knish (More traditional)

Use a gluten-free pie crust (store-bought or homemade) to line a baking dish, then fill with potato mixture and top with another crust.

GF crust tip: Add ½ tsp xanthan gum if your flour blend doesn’t include it for better texture.

Option 2: Crustless Knish Casserole (Easier, lighter)

Layer mashed potatoes, caramelized onions, and cheese in a baking dish—no dough needed!

Ingredients (For Crustless Version)

4 cups mashed potatoes (made with butter/milk of choice)

2 large onions, thinly sliced & caramelized
2 tbsp olive oil or schmaltz
1 egg (or flax egg for vegan)

½ cup sour cream (or dairy-free alternative)
1 tsp salt, ½ tsp black pepper
1 tsp garlic powder

1 cup shredded cheese (optional, cheddar or GF vegan cheese)
GF breadcrumbs or crushed potato chips for topping (optional)

Instructions

Caramelize onions: Cook in oil over low heat for 25–30 mins until golden.

Mix filling: Combine mashed potatoes, caramelized onions, egg, sour cream, and spices.
Layer & bake: Spread in a greased 9×13-inch dish. Top with cheese and GF breadcrumbs if using.
Bake at 375°F (190°C) for 30–35 mins until golden and bubbly.

Tips

Make it vegan: Use dairy-free butter, cheese, and flax eggs.
Extra flavor: Add sautéed mushrooms or diced pastrami.
Meal prep: Assemble ahead and refrigerate overnight before baking.

Why It Works

✅ Naturally GF (no flour needed for the crustless version).
✅ Crispy topping mimics knish dough texture.
✅ Comfort food magic without the gluten!

Serve with mustard or applesauce for the full knish experience. 😊
