Ingredients

Instructions

  1. Step 1: Heat 2 tbsp butter in a large skillet over medium-high heat. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant.
  2. Step 2: Add 10 oz sliced cremini mushrooms and cook for 6-7 minutes, stirring occasionally, until mushrooms release their moisture and start to brown.
  3. Step 3: Stir in 4 cups baby spinach and cook for 2-3 minutes until wilted.
  4. Step 4: Reduce heat to medium-low and add 3 oz softened cream cheese and 1/4 cup heavy cream. Stir constantly until the cream cheese melts and forms a creamy sauce coating the vegetables.
  5. Step 5: Season with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp chopped fresh thyme leaves. Cook for an additional 1 minute and serve immediately.
