Crispy Smashed Brussels Sprouts is a healthy green vegetable that’s incredibly delicious and easy to prepare. They have nice crispy edges and a tender, sweet center. The Brussels sprouts are boiled and smashed, topped with garlic and parmesan and roasted until golden. Even if you think you don’t like Brussels sprouts, you’ll like these. There is a vegan option too!

This is a simple recipe with only a few ingredients; Brussel sprouts, olive oil, garlic powder, parmesan or vegan parmesan, and balsamic vinegar.

I love them with the parmesan but if you’re not eating dairy right now they are also good with vegan parmesan.

The only chopping is to trim the bottom of the Brussels sprouts.

How To Make Crispy Smashed Brussels Sprouts

Here are the basic directions with more detail in the recipe card below.

  1. Trim – Start by trimming the brussel sprouts. Slice off only the very tip of the sprout so the leaves stay together. Remove any discolored leaves.
  2. Boil – Boil the Brussels sprouts in salt water, with enough salt that it tastes like the sea, to give them a firm succulent texture. Cook briefly until they are bright green and barely able to be pierced with a fork. DON’T OVERCOOK.
  3. Drain & Dry – Pour into a colander and run cold water over the sprouts to stop the cooking, then pat dry with a kitchen towel.
  4. Season – Put Brussels sprouts on a baking sheet. Toss with olive oil , garlic powder, ½ teaspoon salt and pepper.
  5. Smash – Arrange the sprouts in a single layer on the baking sheet, with space between each sprout. Flatten the Brussels sprouts with a mason jar or flat measuring cup.
  6. Top with Parmesan – Top each sprout with parmesan or vegan parmesan.
  7. Roast – Roast in the oven until golden brown on top and the edges are crispy.
  8. Remove from the pan – Let cool a few minutes to firm up. Use a spatula to remove from the pan onto a serving dish.
  9. Sprinkle with Balsamic Vinegar

Tips To Make The Best Crispy Smashed Brussel Sprouts

  • Choose medium/small Brussels sprouts, they are sweeter than the big ones. Try and have them be all the same size so they cook evenly.
  • When boiling BE CAREFUL NOT TO OVER COOK THE SPROUTS. If cooked too long they get mushy and release excess sulphur. That is the taste most people don’t like when eating Brussels sprouts. The goal here is to soften them just enough to be able to smash them. They will cook more in the oven.
  • Grate the parmesan on the small holes of a box grater not the big ones.
  • Be sure to dry them before putting onto the pan. This allows them to get nice crispy edges.
  • Spread them out on the baking pan, don’t overcrowd. They need room to get crispy.
  • If after 10 minutes of roasting they aren’t brown, put the baking tray in the broiler for 2-4 minutes to get a nice golden color. If you leave them in the oven too long they will overcook and get mushy.

Storing Crispy Smashed Brussels Sprouts

Store leftovers covered in the refrigerator for up to 3 days.

Reheat in a 350° oven for 5 minutes or lightly pan fry them covered. Don’t microwave, they will get soggy.

    Hello Ingrid. Why do you flatten the sprouts? More surface area to hold cheese? Heidi

    • Ingrid says:

      Hi Heidi, Thanks for the question. Flattening the sprouts allows the surface to hold the cheese and the sprout to crisp up a bit on the bottom and sides. It give them a nice texture. Enjoy the recipe.
