Smashed Brussels Sprouts – America’s Favorite Side Dish

A few years ago Brussels sprouts made an epic comeback.

What was once known as a mushy and bland canned vegetable soon became America’s favorite side dish.

From Brussels Sprouts with Bacon, to this Shredded Brussels Salad, I jumped on the Brussels bandwagon as quickly as I could.

I thought I had made Brussels sprouts in every way known to man.

But I realized there was ONE technique I had not tried…

Smashed Brussels Sprouts.

And if you like this recipe, you’ll use the same technique with these Crispy Smashed Potatoes!

What are Smashed Brussels Sprouts?

Smashed Brussels sprouts are trimmed sprouts that are first boiled in water until tender.  They are then smashed with a glass and roasted in the oven to crispy perfection.

Why smash the sprouts?

Smashing the Brussels sprouts creates more surface area for the Brussels sprouts to crisp up nicely when baked in the oven.

And trust me when I say, you will LOVE Brussel sprouts that are cooked this way!

You can flavor smashed Brussels sprouts with anything from a garlic herb butter to loads of grated Parmesan cheese…

Or you can combine it all together to make the BEST smashed Brussels sprouts recipe!

Smashed Brussels Sprouts Ingredients

The ingredients for this smashed Brussels sprouts with Parmesan cheese recipe are easy to find.

There are also a few substitutions you can make depending on the ingredients you have on hand.

• Brussels Sprouts – Obviously!  The mesh bags full of sprouts are the easiest to find.  You can also use the trimmed Brussels sprouts found in the refrigerated area of your produce section.
• Butter – If you are vegan or dairy-free you can also use olive oil or vegan buttery sticks instead.
• Fresh Thyme – Fresh rosemary or dried herbs can also be used with only a slight affect on taste.
• Garlic – Crushing the garlic cloves is a crucial step to ensure the sprouts get an equal amount of the garlicky goodness!  You can also substitute with garlic powder if that is what you have on hand.
• Parmesan Cheese – Make sure you get grated Parmesan cheese and not shredded for the best results.  If you are dairy-free or vegan you can also substitute with a vegan Parmesan cheese.
• Salt & Black Pepper – Please feel free to adjust these to your preference.
