How to make Crispy Potato Casserole

First, was the russet potatoes and pat them dry. 

Next, dice them into small chunks and place in a glass casserole dish.

Sprinkle on the thyme, salt, pepper, garlic powder, and onion powder.

Drizzle the olive oil over the potatoes and use your hands to toss them until the oil coats the potatoes.

The potatoes should be well coated in oil, which will help get them super crispy on all sides.

Spread out the potatoes in an even layer to make sure that they cook evenly.

Roast at 425 degrees until potatoes are crispy on all sides, stirring and flipping every 15 – 20 minutes.

Pro tip: use a spatula every time to scrape up potatoes that stick to the dish.

This is where you get all those delicious crispy bits from!

The secret is in the depth of flavor you get from roasting the potatoes for hours.

The ingredients themselves are simple..but the real magic happens in the oven!

Once the potatoes are almost done cooking, make your garlic and onion mixture.

Dice up the fresh garlic and onion and add it to a skillet with a touch of olive oil.

Cook for 10 – 15 minutes , stirring often, until onions are caramelized and soft but not burned.

Those caramelized bits will add a next level of flavor to this dish!

Once the potatoes are done, you will mix in the caramelized onion and garlic with a spoon until it is all combined.

The goal is to get the potatoes as crispy as possible without burning.

You will take them out every 20ish minutes and scrape and stuck pieces from the bottom of the pan.

The easiest way to do this is to use a spatula upside down to scrape up any stuck potato edges.

The method is the same one that I use to make my simple vegan breakfast hash and my sweet potato hash.

I even use hash in my vegan breakfast burritos for crazy flavor!

At the end, you will have tender potatoes with crispy bits that just melt in your mouth.

I could literally eat this every week and never get sick of it!

And trust me…the cook time is so worth it. Just wait until you see how fast it will disappear when you make it!

I usually make a double batch when I take it anywhere.

And there are no leftovers when I do!

Famous Crispy Potato Casserole

Yield: 6 servings
Prep Time: 20 minutes
Cook Time: 1 hour 30 minutes
Total Time: 1 hour 50 minutes

This famous crispy potato casserole is a guaranteed crowd pleaser! The holy grail of vegan potato recipes!


  • 3 pounds russet potatoes, diced into small chunks
  • 2 teaspoons dried thyme
  • 2 teaspoons sea salt
  • 1 teaspoon pepper
  • 1 tablespoon garlic powder
  • 1 teaspoon onion powder
  • scant ½ cup olive oil
  • 1 yellow onion, diced
  • 6 cloves of garlic, finely diced or minced


  1. Preheat oven to 425 degrees
  2. Dice potatoes and place in a glass 13 X 9 pyrex baking dish
  3. Sprinkle potatoes with thyme, salt, pepper, and garlic and onion powder
  4. Pour on olive oil and toss the potatoes until spices and oil are well coated (it will be very oily - you will need the oil to help with roasting)
  5. Spread out potatoes into an even layer so that they cook evenly
  6. Roast potatoes at 425 degrees for around 1.5 hours, checking every 20 minutes
  7. Every 20 minutes, remove potatoes from oven and use a spatula to scrape any stuck pieces from the bottom of the pan and toss potatoes around.
  8. Cook for approximately 1.5 hours, or until potatoes are crispy and tender
  9. Once potatoes are almost done, dice up a yellow onion and 6 cloves of garlic
  10. Sautee onion and garlic with a touch of olive oil in a skillet on medium high heat
  11. Sautee for 10-15 minutes, or until caramelized and cooked down
  12. Once potatoes are finished cooking, transfer onion mixture to the dish with the potatoes and stir
  13. Serve and enjoy!


1. It's important to check on the potatoes every 20 minutes since we are roasting at a high temperature. To avoid burning, make sure to use a spatula to scrape sticking pieces from the bottom and toss around.

2. The potatoes will soften as they are out of the oven, but the flavor is insanely good! They reheat well, just keep in mind that they will be more crispy straight out of the oven.

This recipe looked really good, but I am ok with eating meat, even though I don't normally overdo it.

I've had 4 squirrels in the freezer since this past January, and have been wonder what to do with them. I was tired of the same old squirrel recipes, so I deboned them, sautéed them in a bit of garlic butter (With lots of extra freshly minced garlic), then added them to this otherwise unchanged recipe.

Delicious. Next time I think I'll add in 2 pounds of Pepperidge Farm Maple Sausage, or just season up a batch of venison sausage myself.

Do you know if this would freeze well? I’d like to cut it in pieces and freeze individually.
