Best Smashed Potatoes

There are countless ways to make smashed potatoes but the most important elements are 1) using buttery gold potatoes, lots of garlic, and parmesan cheese, 2) adding butter or olive oil, and seasonings, and 3) baking until crispy.

Smashed potatoes are totally customizable so make them the way you like them. Try other types of cheese, add crumbled bacon or small pieces of steak, use olive oil instead of butter, or try other seasonings and herbs.

How to make Garlic Parmesan Smashed Potatoes:

Step 1
Boil potatoes. Place baby potatoes in a large stock pot. Cover with water and bring to a boil over high heat. Reduce heat and add a good amount of kosher salt. Cook until the potatoes are fork tender. Use a colander to drain. Cool slightly.

Step 2
Make garlic butter. In a small bowl, combine the softened butter, smashed garlic, onion powder, kosher salt, and freshly ground black pepper. Mix until well combined.

Step 4
Add garlic butter. Use a pastry brush and divide garlic butter evenly over each smashed potato.

Step 5
Add cheese. Divide the freshly shredded parmesan cheese on top of each potato. Then add a drizzle of olive oil over the top (if desired).

Step 6
Bake. Bake smashed potatoes for 15-20 minutes in preheated oven. You may want to broil for a few minutes too to add extra crispiness.

Step 7
Serve. Serve potatoes with extra salt and pepper (if needed), chopped cilantro, and a dollop of sour cream.

Store leftover smashed potatoes in an airtight container for 3-4 days.

Recipe FAQs:

Do I need to peel the potatoes?

No, leaving the skins on adds texture and flavor, plus they help hold the potatoes together when smashed.

What’s the best way to smash potatoes?

We prefer to pierce the top of each potato so that the skin will break open on the top (allowing the “meat” of the potatoes to be exposed) before using a glass to smash them.

How do I get the potatoes crispy?

After smashing, brush the potatoes with the garlic butter mixture and roast them at a high temperature or broil them.

Can I use pre-grated parmesan cheese?

Freshly grated parmesan is recommended for better flavor and melting, but pre-grated works in a pinch.

Can I prep these ahead of time?

Yes, you can boil and smash the potatoes ahead of time, then refrigerate them until ready to add toppings, roast, and serve.
