Ingredients
- 1 medium (about 5 cups riced) cauliflower head
- 8 oz, sliced cremini mushrooms
- 3 tbsp extra virgin olive oil
- 3 cloves, minced garlic cloves
- 1 tbsp, chopped fresh thyme leaves
- 1 tsp sea salt
- 1/2 tsp black pepper
- 1 small, finely chopped yellow onion
Instructions
- Step 1: Remove leaves and core from 1 medium cauliflower head and pulse in a food processor until it resembles rice grains, about 5 cups.
- Step 2: Heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 small finely chopped yellow onion and sauté for 4 minutes until softened.
- Step 3: Add 8 oz sliced cremini mushrooms and 3 minced garlic cloves to the skillet, sautéing for 5-6 minutes until mushrooms release moisture and start to brown.
- Step 4: Stir in the riced cauliflower, 1 tbsp chopped fresh thyme, 1 tsp sea salt, and 1/2 tsp black pepper. Cook, stirring frequently, for 6-8 minutes until cauliflower is tender but not mushy.
