Preheat the oven to 425 degrees F.
Line a baking sheet with a piece of parchment paper, or place a reusable silicone baking mat on your baking sheet. Set aside.
Cut your head of cauliflower into bite-sized pieces by cutting the cauliflower head in half, and then in half again. Carefully slice out the middle stem. The pieces of cauliflower will easily pull apart.
Place the cut-up cauliflower into a colander or a salad spinner basket, and rinse the cauliflower using water. Drain the water and either pat dry with a towel or using your salad spinner, spin the excess water off.
Transfer the cauliflower to a large mixing bowl. You can also save time by purchasing a bag of pre cut cauliflower.
Finely chop (mince) your 2 cloves of garlic and then add to the bowl with the cauliflower.
In a small bowl add the salt, pepper, smoked paprika, cumin, oregano, and onion powder. Using a small whisk or a fork stir to combine the spices together.
Drizzle the olive oil over the top of the cauliflower. Using a spatula or wooden spoon, stir to evenly coat the cauliflower with the olive oil.
Sprinkle half of the spice mixture over the cauliflower. Then using your spatula or wooden spoon, toss or stir to fully combine.
Add the remaining spice mixture to the bowl and then, using your spatula or wooden spoon, stir to fully combine making sure that every cauliflower piece has some of the spice mixture on it.
Transfer the cauliflower to the lined baking sheet. Spread out the cauliflower so it’s evenly distributed on the baking sheet.
Add to the preheated oven. Bake at 425 degrees for 20 minutes or until the edges of the cauliflower are golden brown.
