Preheat oven to 425 degrees F and line large baking sheet with parchment paper.
Remove green leaves and cut cauliflower head into 4 quarters, starting at the base and slicing through the core. Lay each quarter on a cutting board, angle your knife and cut florets from the stem. Then cut through the quarter one more time lengthwise and separate with hands into small steaks.
Place cauliflower in the center of previously prepared baking sheet, drizzle it with olive oil and butter, and toss to coat.
Sprinkle evenly with garlic powder, onion powder, smoked paprika, salt and pepper. Stir well to coat evenly.
Spread cauliflower in a single layer so florets are not touching each other. Bake for 25 minutes or until soft to the touch with a fork.
Serve hot with your favorite protein and grain.
Notes
Store: Refrigerate in an airtight container for up to 3 days. Cauliflower will become softer in but still delicious.
I don't recommend to freeze baked cauliflower leftovers.
