Ingredients For Smashed Brussels Sprouts
- 1½ pounds medium Brussels sprouts, trimmed (this size is really important!)
- 1 cup grated Parmigiano-Reggiano cheese (don't use pre-shredded if possible – the quality makes a difference)
- 1½ teaspoons garlic powder
- ½ teaspoon salt
- Parchment paper for baking sheets
I always grab medium-sized sprouts because they cook evenly and give you the perfect ratio of tender inside to crispy outside. Sarah watches me pick them out at the market now because she's learned that size matters!

How To Make Crispy Garlic-Parmesan Smashed Brussels Sprouts
Preparing Your Brussels Sprouts
- Preheat your oven to 425°F and get your baking sheets ready with parchment paper. There's nothing worse than burnt-on cheese, so trust me on the parchment.
- Bring a large pot of water to a boil and add your trimmed Brussels sprouts. Let them cook for about 10 minutes until they're completely tender. You want them soft enough to smash easily, but not falling apart. The knife should slide through without any resistance.
- Drain them really well and let them sit in the colander for about 5 minutes. This is a step people skip, but it actually matters. You want them dry-ish so the cheese crisps up properly instead of steaming.
Creating The Parmesan Crust
- Mix your Parmigiano-Reggiano and garlic powder together in a medium bowl. Get it really combined so the garlic is evenly distributed. I like to use a fork to break up any little clumps.
- Sprinkle small mounds of this cheese mixture onto your parchment paper, making little circles about 1½ inches apart. I use a rounded teaspoon for each mound. Don't skimp here – you want enough cheese to create that beautiful crispy crust.
- Place one Brussels sprout on top of each cheese mound, then here's the fun part – smash it flat with the bottom of a sturdy measuring cup or cup. I aim for about ¼ inch thick. Alex actually enjoys doing this part, so it's become a little helper task in our kitchen.
Roasting To Crispy Perfection
- Sprinkle the remaining cheese mixture over the top of each smashed sprout. This is what creates those gorgeous crispy edges when everything roasts together.
- Slide everything into your preheated oven for about 10 minutes. Watch for the cheese on the bottom to turn golden brown and crispy. You'll see them starting to brown around the edges – that's exactly what you're looking for.
- Carefully flip each sprout using a spatula so the crispy cheese side faces up. I won't lie – this step requires a gentle hand, but they come off pretty easily.
- Sprinkle with salt and transfer to a serving platter. The cheese will still be hot and slightly melty on top, which is absolutely perfect.
Storage And Reheating Your Smashed Brussels Sprouts
These taste best eaten warm right out of the oven, but honestly, leftovers are still fantastic. I store them in an airtight container in the refrigerator for up to three days. Unlike some roasted vegetables that get mushy, these actually stay fairly crispy because of the cheese coating.
To reheat, I pop them on a baking sheet at 350°F for about five minutes just to warm them through. Don't microwave them – that's the one thing that'll make them lose their crispiness. Trust me, I learned this the hard way one morning when I was in a rush!
They'll keep in the freezer for up to a month if you want to make them ahead. Just thaw them in the refrigerator overnight and reheat as described above. I love doing this before we have company because it takes away one stress on dinner day.

Tips And Tricks For Perfect Crispy Garlic-Parmesan Smashed Brussels Sprouts
Here's what I've learned after making these about a hundred times:
- Size matters more than you'd think – If your Brussels sprouts are wildly different sizes, the big ones won't cook through while the tiny ones start to burn. Spend an extra minute picking similar-sized ones.
- Don't skip the drying step – Those extra five minutes in the colander really do make the cheese crisper. It's not glamorous, but it works.
- Real Parmigiano-Reggiano makes a huge difference – I know pre-shredded is easier, but the quality difference is noticeable. Plus, you'll actually use the whole block because these are so good.
- Watch your oven temperature – If your cheese is burning before the Brussels sprouts are tender, your oven might be running hot. Start checking around the 8-minute mark.
- The cheese should be golden, not brown – Golden brown means crispy and delicious. Dark brown means you've gone a bit too far. I learned this when I got distracted helping Sarah with homework!
- Wondering if you can add anything else? – I've tried mixing in fresh herbs like thyme, but honestly, the garlic and Parmesan are perfect on their own. Sometimes simple is actually better.
Frequently Asked Questions About Crispy Smashed Brussels Sprouts
How do you get crispy garlic-Parmesan smashed Brussels sprouts without burning the cheese?
The key is not overcrowding your baking sheet and keeping your oven at the right temperature. If your cheese is burning before the Brussels sprouts are tender, try lowering the temperature to 400°F and cooking for a few extra minutes. Also, make sure your Brussels sprouts are fully cooked and tender before roasting – this ensures everything finishes at the same time. I always start checking around the 8-minute mark and pull them out as soon as the cheese is golden brown.
Can I make crispy garlic-Parmesan smashed Brussels sprouts ahead of time and reheat them?
Absolutely! You can prepare them up to three days ahead and store them in an airtight container in the refrigerator. To reheat, place them on a baking sheet and warm at 350°F for about five minutes. The key is not to microwave them – that will make them lose their crispiness. They'll stay in the freezer for up to a month too, which makes them perfect for meal prep before hosting dinner parties.
What size Brussels sprouts work best for smashed Brussels sprouts recipes?
Medium Brussels sprouts are ideal – about the size of a walnut. They're large enough to hold together when smashed but small enough to cook through evenly. If you use sprouts that are too big, the outside will char before the inside is tender. Too small and they'll fall apart during smashing. I spend an extra minute at the market picking through to find the most uniform-sized ones.
Do I need to boil Brussels sprouts before smashing and roasting them?
Yes, boiling is actually essential. It ensures the Brussels sprouts are completely tender before you smash them, which means they'll cook evenly when roasted. Raw Brussels sprouts won't smash properly and won't have that perfect tender-inside, crispy-outside texture. The boiling takes about 10 minutes, and it's really the foundation of this whole recipe working perfectly.
