Crispy Thousand Layer Potato Stacks with Sausage Gravy and Sunny Side Egg
These crispy potato stacks are one of the first recipes that ever went viral for me. Millions of views. Years later, I still come back to them.
They are rich, layered, pressed, seared until golden, and topped with a tight Portuguese sausage gravy and a sunny side egg. The inspiration comes from my time cooking at Palace Kitchen, where we built deep, savory gravies for loco moco that stuck with you.
This is not a quick potato side dish. This is a technique-driven, restaurant-level potato.
And yes, it is worth it.
Why Use Idaho Russet Potatoes?
Use Idaho russets. Do not substitute waxy potatoes.
Russets are high in starch and lower in moisture. That starch content is what allows the layers to bind together when pressed and chilled. It also creates that crispy exterior when seared.
Waxy potatoes will not give you the same structure.

How to Make Crispy Thousand Layer Potato Stacks
Build the Herb Cream:
In a saucepan, melt 8 ounces butter with rosemary and thyme over medium heat.
Once melted and fragrant, whisk in 2 cups half and half. Bring just to a gentle simmer.
Remove from heat and let cool to room temperature. Remove herb sprigs.
Slice and Toss the Potatoes: Using a mandoline, slice potatoes lengthwise to about credit card thickness or slightly thinner.
Slice directly into the herb butter cream mixture. Season with kosher salt.
Gently toss to coat every slice.
Build the Terrine: Line a terrine mold with parchment paper and lightly grease with olive oil or butter.
Shingle the potato slices tightly, layering evenly until the mold is completely full.
Fold parchment over the top. Add another layer of parchment and cover with lid.
Bake at 375 degrees Fahrenheit for 45 to 50 minutes, or until knife tender.
Press and Chill: Remove from oven.
While hot, press with another same-size mold or weighted container.
Let cool to room temperature with pressure on top.
Refrigerate overnight with weight still on.
This step is critical. It compresses the layers and allows the starch to bind everything together.
Slice and Sear: The next day, warm the outside of the mold slightly so the terrine releases cleanly.
Remove, trim edges, and cut into desired portions.
Heat a cast iron skillet with a thin layer of oil.
Sear each portion until deeply golden brown on both sides.
Finish in a 350 degree oven until warmed through.
You are looking for crispy exterior, tender interior.
Portuguese Sausage Gravy: Cook diced Portuguese sausage in a pan until fat renders and sausage is browned.
Remove sausage and reserve fat in pan.
Add 4 ounces butter. Once melted, whisk in 4 ounces flour.
Cook the roux, whisking constantly, until dark brown and nutty.
Slowly whisk in 2 cups beef stock.
Add sausage back in.
Simmer until thick and tight.
Season with MSG, citric acid or lemon juice, and salt to taste.
This should be a thick, glossy gravy.
Finish the Dish: Fry eggs sunny side up.
Place crispy potato stack on plate.
Top with sunny side egg.
Spoon over hot Portuguese sausage gravy.
Finish with chopped chives.
Serve immediately.
Pro Tips for Perfect Potato Stacks
- Press overnight. Do not rush this.
- Slice evenly. Uneven slices create weak structure.
- Sear aggressively. Color equals flavor.
- Use russets only.
FAQ
Can I make potato stacks ahead of time?
Yes. After pressing and chilling, they hold well in the refrigerator for up to three days before searing.
Why are my potato stacks falling apart?
You likely used waxy potatoes or did not press and chill long enough. The starch needs time to set.
Can I skip the pressing step?
No. Pressing is what turns this from layered potatoes into a sliceable terrine.
Can I freeze potato stacks?
You can freeze after baking and pressing. Thaw in refrigerator before searing.
What can I substitute for Portuguese sausage?
Chorizo works well. Any cured sausage with strong flavor and fat content will build a similar gravy base.
