Quiche with Potato Crust

If you’re anything like us, traditional pie crust in quiche just doesn’t do it. It can feel heavy, soggy, and honestly a bit unnecessary when there are better options sitting right in the kitchen. Around here, we skip the pie crust entirely and build our quiche on a golden potato crust instead. It adds flavor, holds together beautifully, and makes the whole dish feel more like a hearty dinner than a brunch side.

This version came together from what we had growing and what needed using. Italian Sausage for richness, Mushrooms for depth, Bok choy and Okinawa spinach for greens, fresh herbs for brightness, and sharp Old English cheddar to pull it all together. It’s one of those meals that feels a little fancy but is actually very forgiving.

Why Use a Potato Crust Instead of Pie Crust

Potato crust changes the entire texture of quiche. Instead of a soft pastry base, you get crispy edges and a sturdy bottom that holds up to hearty fillings.

A few reasons we keep coming back to it:

• It tastes better with savory fillings

• It holds up well to moisture from vegetables

• It feels more like a full dinner than breakfast

• It uses simple ingredients most kitchens already have

• It’s naturally gluten-free if that matters to you

Plus, if you grow potatoes or keep a stash from the garden, it’s a practical way to use them.

Ingredients:

For the Potato Crust

• 10 or so small Potatoes, unpeeled and cut in half

• 1 tablespoon olive oil

• Salt and black pepper to taste

  
  

For the Filling

• 1 pound Italian sausage (mild or hot, your choice)

• 1 to 1½ cups mushrooms, sliced

• 1 cup chopped Bok choy (or any green of your choice)

• 1 cup Okinawa spinach, chopped (or any green of your choice)

• 2 to 3 tablespoons fresh herbs (thyme, parsley, oregano, or basil work well)

• 2 cups shredded Old English cheddar (again, how much you want to use is entirely up to you as well as what kind of cheese. This is what we use.)

• 6-7 large eggs

• 250ml or 250g or 8.5 oz (its all the same measurement really) of heavy Cream (Again, feel free to substitute with Half and Half or Milk)

• Salt and pepper to taste

• 1 TBSP of Worcestershire Sauce

Step 1: Build the Potato Crust

1. Preheat your oven to 425°F.

2. Boil your Potatoes and let them cool down. (I pressure can whole new Potatoes so I just opened a jar here).

3. Cut them in half and toss them with olive oil, salt, and pepper.

4. Press the potatoes firmly into a greased pie dish or cast iron skillet. Work them up the sides so the crust forms a bowl shape. It works well if you put some parchment paper on top before you start pressing and a lot less messy for your hands.

5. Bake the crust for 20 to 25 minutes, or until the edges start turning golden brown.

6. Remove from the oven, let cool while you prepare your other ingredients. Lower the oven temperature to 350°F.

Step 2: Cook the Filling

1. In a skillet over medium heat, cook the Italian sausage until browned and fully cooked. Break it into small pieces as it cooks.

2. Remove the sausage and set it aside OR If you use Freeze dried Mushrooms like we do, you can omit Step 3 and simply add them to the pan.

3. In the same pan, cook the mushrooms until they release their moisture and begin to brown. Add the bok choy and Okinawa spinach and cook until wilted.

4. Return everything to the same pan.

Step 4: Assemble the Quiche

1. Shred the Cheese.

2. Spread the sausage and vegetable mixture evenly into the baked potato crust.

3. Sprinkle the shredded Old English cheddar across the top.

4. Pour the egg mixture over the filling, making sure it spreads evenly through the dish.

5. Add more Cheese on top.

Step 5: Bake Until Set

Bake at 350°F for about 40 minutes, or until the center is set (poke a toothpick or a knife inside, if it comes out clean you're good!) and the top is lightly golden.

Let the quiche rest for 10 to 15 minutes before slicing. This helps everything firm up and makes cleaner slices.

What Makes This Combination Work

This mix of ingredients hits a lot of the right notes:

• Italian sausage brings richness and seasoning

• Mushrooms add depth and a savory backbone

• Bok choy gives texture and mild sweetness

• Okinawa spinach adds color and nutrition

• Fresh herbs keep it from feeling heavy

• Old English cheddar gives sharpness that cuts through the richness

And the potato crust ties it all together with a crisp, golden base.

Tips From Our Kitchen

Use what you have. This recipe adapts easily. Kale, Swiss chard, regular spinach, or even leftover roasted vegetables work well.

Cast iron works beautifully. If you have a well-seasoned skillet, it makes an excellent quiche pan and helps crisp the potato edges.

Make It Your Own

This quiche is more of a template than a strict recipe. Once you get comfortable with the potato crust method, the filling options are nearly endless.

Try swapping:

• Bacon or ham instead of sausage

• Goat cheese or feta instead of cheddar

• Leeks or onions instead of bok choy

• Sweet potatoes for a slightly sweeter crust

It’s a great way to clean out the fridge without making something that feels like leftovers.

Why This Makes a Great Dinner

Quiche often gets labeled as breakfast food, but this version is solidly dinner-worthy. The sausage makes it filling, the greens add balance, and the potato crust gives it enough substance to stand on its own.

Serve it with:

• A simple garden salad

• Roasted vegetables

• Fresh sliced tomatoes

• Or just by itself on a busy night

Either way, it’s one of those meals that looks impressive, smells incredible while baking, and disappears fast once it hits the table. And best of all? No pie crust required!
