If you’re looking for a simple low carb side that works with almost any dinner, this spinach mushroom cauliflower rice is one of my favorites. It’s made in one pan with everyday ingredients and comes together quickly on busy nights.
In the summer, I sometimes use cauliflower from my garden. The rest of the year, frozen riced cauliflower makes this recipe fast, affordable, and always ready when I need an easy vegetable side.
Ingredients
- 10 oz frozen riced cauliflower
(or about 2½ cups fresh riced cauliflower) - 1 tbsp olive oil or butter
- 1/2 cup chopped onion
- 2 cloves garlic, minced
- 2–3 cups sliced mushrooms
- 2 cups fresh spinach, chopped
(or 1 cup of frozen chopped spinach) - 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp garlic powder
- 1/4 tsp onion powder
Instructions
- Heat olive oil (or butter) in a large skillet over medium heat.
- Add chopped onion and sauté for 2–3 minutes, until soft.
- Stir in garlic and mushrooms. Cook 4–5 minutes, until mushrooms release their moisture.
- Add frozen cauliflower rice and all seasonings.
- Cook uncovered for 10–15 minutes, stirring occasionally, until the moisture cooks off and the cauliflower looks fluffy (not watery).
- Stir in spinach and cook 1–2 minutes, just until wilted.
- Taste and adjust salt and pepper as needed.

Notes and Tips
- Save money on cauliflower: I often buy a 12 oz bag of frozen cauliflower florets and pulse them in my food processor instead of buying pre-riced cauliflower. It usually saves me about $1 per bag and works the exact same.
- Fresh or frozen both work: Use fresh riced cauliflower when you have it, and frozen when you don’t — this recipe is forgiving either way.
- Make it richer: Stir in a little butter or sprinkle Parmesan on top just before serving for extra flavor.
- Add protein: This is great as a side, but you can also add cooked chicken, sausage, or shrimp to make it a full meal.
- Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a skillet for best texture.
This spinach mushroom cauliflower rice is especially delicious served alongside my Keto Chicken Bruschetta for an easy, flavorful low carb dinner.
