When you make creamed spinach in the slow cooker, it has all the same rich creaminess you get with the regular recipe, but it is so simple to make. This recipe takes only about 10 minutes of active prep time to prepare. If you're in a rush, you can cook this spinach on high. It'll take anywhere for 1 to 3 hours, depending on how hot your slow cooker gets. Serve as a side with everything from beef to pork to chicken. You can even serve this creamed spinach as a sauce tossed with spaghetti or linguine. Grate a little more parmesan cheese over the top, and you've got a complete meal.
