Step‑by‑Step Instructions for Mushroom & Spinach Cauliflower Rice

Step 1: Cook the Cauliflower Rice
Begin by cooking the frozen riced cauliflower according to package instructions, typically 4–6 minutes in the microwave, until it’s tender and heated through. If using fresh cauliflower, grate it or pulse in a food processor until it resembles rice, then cook in a large skillet over medium heat for about 5 minutes, stirring occasionally until slightly softened.

Step 2: Sauté the Onions
While the cauliflower rice cooks, heat 1–2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onions and sauté for 3–4 minutes until they become translucent and start to soften. This step adds a lovely sweetness and depth of flavor to your Mushroom & Spinach Cauliflower Rice.

Step 3: Add the Mushrooms
Next, stir in the sliced mushrooms to the skillet with the onions. Sauté for about 5 minutes, allowing the mushrooms to cook down and turn golden brown. They should release their moisture and develop a rich, earthy flavor that perfectly complements the other ingredients.

Step 4: Incorporate the Garlic
Add the minced garlic to the skillet with the sautéed onions and mushrooms. Cook for an additional 1 minute, stirring frequently, until the garlic becomes fragrant and aromatic. This step is key to infusing your Mushroom & Spinach Cauliflower Rice with a delightful garlicky aroma.

Step 5: Mix in the Cauliflower Rice and Soy Sauce
Now, incorporate the cooked cauliflower rice into the skillet. Drizzle in 1–2 tablespoons of soy sauce (or coconut aminos) and stir until the rice absorbs the sauce evenly, about 2–3 minutes. You’ll know it’s ready when the mixture is heated through and well combined, creating a savory base for your dish.

Step 6: Add the Spinach
Finally, fold in the spinach and cook for 1–2 minutes, just until it wilts and retains its vibrant green color. This final addition not only enhances the visual appeal of your Mushroom & Spinach Cauliflower Rice but also boosts the nutritional profile of this tasty low-carb side dish.
