Directions
-
Break the fettuccine pasta in half and place it in the bottom of your slow cooker.
-
In a saucepan over medium heat, melt the butter. Whisk in the heavy cream, milk, garlic powder, onion powder, black pepper, and salt until well combined.
-
Pour the cream mixture over the pasta, ensuring the noodles are coated and submerged.
-
Add the sliced mushrooms and fresh spinach on top.
-
Cover and cook on low for 2–3 hours, or until the pasta is tender.
-
Stir in the grated Parmesan cheese until fully melted and smooth.
-
Let the pasta rest for 10–15 minutes to allow the sauce to thicken and the flavors to meld.
Serve hot, garnished with chopped parsley.

Dairy-free version: Substitute butter, cream, and milk with plant-based alternatives like coconut milk and vegan butter.

Pasta swap: Try penne, rotini, or your favorite pasta shape for a fun texture change.
