Stovetop - Heat 1 tbsp of olive oil over a large skillet. Add cauliflower rice, season to taste and give it a stir. Cover with a lid (to make rice tender) and cook for 5 to 8 minutes, stirring a couple of times in between.
Oven - Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper. Drizzle riced cauliflower with oil and season to taste, then spread it out evenly on the prepared baking sheet. Roast in hot oven for 10 to 15 minutes, stirring halfway through.
Microwave - Place keto rice to a microwave safe bowl, drizzle with oil and season to taste. Cover the bowl, then microwave on high for 4 to 5 minutes, until the rice is tender crisp.
Instant Pot - Place the cauliflower rice in the instant pot, drizzle with oil, and season to taste. Set the pot to "Sauté" mode and cook for 4 to 5 minutes, stirring occasionally, until the rice is ready. Do not use the pressure cooking function, as it will overcook the cauliflower rice and make it mushy.
