**Preheat the oven**
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil for easy cleanup.
**Prepare the coating**
In a mixing bowl, combine the breadcrumbs, Parmesan cheese, salt, and pepper. Stir to mix evenly.
**Coat the cauliflower**
Toss the cauliflower florets in olive oil until evenly coated. Then, toss the florets in the breadcrumb mixture, pressing lightly to ensure the coating sticks.
**Arrange and bake**
Spread the coated cauliflower florets in a single layer on the prepared baking sheet. Bake for 20–25 minutes, flipping halfway through, until golden brown and crispy.
**Serve**
Remove from the oven and let cool slightly before serving. Serve with your favorite dipping sauce, such as ranch, marinara, or a spicy aioli.
