Ingredients (Serves 4)
-
1 pound pasta (penne, fettuccine, rigatoni, or your favorite shape)
-
2 cups jarred Alfredo sauce (store-bought or homemade)
-
2 cups fresh spinach leaves (packed)
-
1 cup grated Parmesan cheese
Instructions
-
Spray or grease your slow cooker to prevent sticking.
-
Add the uncooked pasta to the bottom of the slow cooker.
-
Pour in the Alfredo sauce, followed by 2 cups of water (or broth for extra flavor).
-
Stir in the fresh spinach and mix gently to coat everything.
-
Cover and cook on LOW for 2–3 hours, checking after 90 minutes for doneness. Stir once or twice during cooking if possible.
-
Once pasta is tender, stir in the grated Parmesan cheese. Mix until melted and creamy.
-
Serve warm, garnished with extra Parmesan, black pepper, or red chili flakes if desired.
Tips for Best Results
-
Use shorter pasta shapes like penne, rotini, or shells — they cook more evenly in the slow cooker.
-
If using fresh homemade Alfredo sauce, reduce the added water to 1½ cups.
-
Add cooked chicken or shrimp during the last 20 minutes to heat through without drying out.
-
Stir in a splash of milk or cream at the end if the sauce is too thick.
