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 and Air Fryer Brussels Sprouts to this Shredded Brussels Salad, I jumped on the Brussels bandwagon as quickly as I could.
I thought I had made them 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 can use the same technique with these Crispy Smashed Potatoes!
Ingredients
For the exact measurements and detailed instructions, you can jump to the recipe.
- Brussels Sprouts. Obviously! The mesh bags full of fresh Brussels sprouts are the easiest to find. You can also use the trimmed sprouts found in the refrigerated area of your produce section.
- Butter. If you are vegan or dairy-free you can swap the butter out for extra-virgin olive oil or vegan buttery sticks instead.
- Fresh Thyme. Fresh rosemary or dried herbs are other options with only a slight effect on taste.
- Garlic. Crushing the fresh 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 select a vegan Parmesan cheese.
- Salt & Black Pepper. Please feel free to adjust these to your preference.
How to Make Smashed Brussels Sprouts
Jump to the recipe for the full instructions, ingredient amounts, and a printable recipe.
- Prepare the Brussels sprouts. Use a knife to trim the ends off of the fresh sprouts and remove the outer leaves.
- Boil and blanch. Bring a large pot of water to a boil, then add the sprouts. Boil for about 10 minutes or until tender. Immerse the cooked Brussels in an ice water bath to stop the cooking process. If you skip this step, they’ll keep cooking, and you’ll end up with a mushy texture at the end. (This whole process is also known as blanching.) Pat dry thoroughly with a clean kitchen towel or paper towels.
- Smash the sprouts. Line a sheet pan with parchment paper and place the Brussels sprouts on the sheet cut side-up in a single layer. Push down each Brussels sprout with the bottom of a glass until it is flattened to about ½-inch tall.
- Add the seasonings. Whisk together the butter, garlic, thyme, salt, and pepper in a small mixing bowl. Pour equal amounts of the butter sauce over each sprout. Sprinkle all of them with Parmesan cheese.
- Bake in the oven. Cook the smashed and seasoned sprouts in the preheated oven for 20-22 minutes. You will know they are done when you see crispy edges, and when checked with a fork or knife the middle is tender.
- Serve. Sprinkle the roasted sprouts with remaining cheese and additional fresh thyme, if desired.
Meal Prep and Storage
- Prep-Ahead: Trim, boil, dry, and smash the sprouts, then refrigerate up to 24 hours in advance. On the day of serving let them come to room temperature, top with the sauce and cheese, and bake.
- Storage: Keep leftover smashed sprouts in an airtight container in the refrigerator for up to 3 days.
- Freezing: Seal in a freezer-safe airtight container for up to 12 months.
- Reheating: Bake in a 350°F oven until warm or reheat in a skillet over medium-low heat.
FAQs
It’s important to cut the ends off of the sprouts before you cook them to remove the fibrous part that isn’t very palatable. You only need to slice up to where the leaves start.
The best way to remove some of the bitterness of Brussels sprouts is to buy the freshest vegetables possible and to remove the outer layer of leaves before cooking. The cooking method also affects the flavor of this side dish. Using the oven or a hot pan to caramelize the edges brings out this veggie’s natural sweetness.

Question/ in the ingredients you listed Garlic yet in the directions I’m not seeing when Garlic is added. Is it minced and added into the mixture or is it sort of sautéed/baked along with the Brussel Sprouts? This looks amazing, I’d love to add this to my upcoming Thanksgiving meal.
Thank you for catching that! I’ll update it now.
Yes, the garlic goes into the butter mixture that you pour over the smashed sprouts.
These will be great for Thanksgiving. Thank you for the recipe!
Yay!! I’m so excited to hear what you think 🙂
