Potato Recipes

I love potatoes of all types, so I’m always experimenting with new recipes—some from friends or family and others that I come up with on my own. I also take traditional recipes and tweak them.

This parmesan potato bake idea started with a recipe from a church cookbook. I added a couple of ingredients to make it even better.

My husband and I both love these buttermilk garlic mashed potatoes. They’re creamy and packed with so much deliciousness you’ll definitely want seconds.

We also enjoy these fun and festive Tex Mex ranch potatoes. In fact, I like them so much I’ve eaten them as meal, with nothing else.

Parmesan Potato Bake Ingredients

When I looked at the original recipe, I thought it looked good. But I also felt that it could be so much better with more than one form of garlic, a couple of types of parmesan cheese, and some thyme.

It is so delicious, but if you want to change something else to suit your family’s taste, go for it. As soon as you cook this dish, it becomes your recipe.

I placed a printable recipe card with the ingredients, measurements, and complete directions toward the bottom of this post.

Here are the ingredients you’ll need to make this yummy parmesan potato bake:

  • Potatoes cut into 1/4” rounds
  • Thinly sliced onion
  • Grated parmesan cheese
  • Shredded parmesan cheese
  • Minced garlic
  • Garlic powder
  • Dried ground thyme
  • Olive oil
  • Salt and pepper

You can adjust any or all of the ingredients by adding, subtracting, or substituting. I do that all the time, and I think that’s the best way to discover new recipes.

Prepare to Cook

Gather all of the ingredients and put them close by so you don’t have to look for them while you’re cooking.

I’ve gotten so distracted in the past that I messed up entire meals, simply because I couldn’t find something I needed.

There are a couple more things to prep for this dish. Preheat the oven to 375 degrees F and spray a casserole dish with nonstick cooking spray.

How to Make Parmesan Potato Bake

Now it’s time to put everything together. It’s not difficult, so relax and enjoy the process. 

First, combine the sliced potatoes and onions in a large bowl. Secondly, add the olive oil and toss the potatoes until they are all well coated.

Next, get a small bowl.

Combine the grated parmesan, minced garlic, garlic powder, salt, pepper, and thyme. Stir until everything is mixed.

Now it’s time to put it all together in the casserole dish. Start by putting a layer of potatoes and onions in the bottom of the casserole. Sprinkle 1/3 of the parmesan and garlic mixture over the top.

Add another layer of potatoes and onions, followed by more of the garlic and parmesan mixture.

Repeat these steps until all of the potatoes, onions, and seasonings are in the casserole dish. Finally, sprinkle all of the shredded parmesan cheese over the top.

Cover the casserole with foil. I lightly spray the underside of the foil with nonstick cooking spray to keep the topping from lifting off when I remove the foil.

Place the covered casserole in the oven and bake for an hour. It won’t be long before the aroma starts to waft through your house.

After an hour, remove the foil and return the casserole to the oven for another 15 minutes, or until the top is golden brown.

This potato dish is best served hot.

If you’re cooking for a large crowd, you can double the recipe and bake it in a larger casserole dish.
