Make my crispy smashed brussels sprouts using just 5 simple ingredients! This recipe is an easy, healthy side dish with a cheesy flavor.
Preheat the oven to 425 degrees F (218 degrees C).
Boil a large pot of boiling water with 2 teaspoons of sea salt. Carefully add the brussels sprouts, return to a boil, and boil for 8-10 minutes, until tender (soft enough to insert a knife or fork). Run the sprouts under cold water or plunge into an ice bath to prevent overcooking. Drain and pat dry with a paper towel.
In a large bowl, toss the brussels sprouts together with the olive oil, garlic powder, remaining 1/2 teaspoon of sea salt, and cayenne pepper. Add 5 tablespoons (about 1/3 cup) of the parmesan cheese (if using) and toss again.
Spray a large baking sheet with cooking spray or brush with oil. Arrange the sprouts in a single layer, with about 1.5-2 inches of space between them.
Using the bottom of a glass or mason jar, push down on the sprouts to smash them flat. Sprinkle the remaining 3 tablespoons of grated parmesan cheese on top (optional).
Roast smashed brussels sprouts for 25-30 minutes, flipping halfway through, until golden and crispy on both sides.
