Instructions
Set the oven rack in the center and preheat to 400°F.
Break the cauliflower into 1-inch pieces. Rinse and pat very dry, then add to a large mixing bowl.
In a medium bowl, whisk the olive oil, garlic powder, salt, and pepper. Add the cauliflower and toss to coat evenly.
Spread the cauliflower florets on a large sheet pan in a single layer and roast for 10 minutes.
While the cauliflower roasts, cook the spaghetti in a large pot of salted water. Drain and toss with butter or olive oil, a pinch of salt, and chopped parsley.
In another bowl, mix the breadcrumbs, melted butter, cheese, parsley, Italian seasoning, and salt.
Remove the cauliflower from the oven. Slide the pieces slightly closer together and scatter the breadcrumb mixture evenly over the top.
Return to the oven and bake another 5 to 10 minutes, until the topping is golden brown.
Plate the spaghetti on a platter and scatter the roasted cauliflower over the top.
Finish with lemon zest and red chili flakes, if using.
Serve with extra Parmesan at the table.
