Rinse and remove the stems from spinach. Bring water to a boil in a pot, cook spinach for under 1 minute and drain them with a colander. Transfer the spinach to a bowl of cold water and cool down for 2 minutes. Drain and squeeze out the excess water from spinach as much as possible. Chop the spinach into small pieces and set aside.
Melt the butter in a large skillet (or a non-stick frying pan) with medium-high heat. Add garlic and onion, saute until golden brown and aromatic. Add all-purpose flour and stir well.
Transfer the dish to a baking dish and evenly sprinkle the rest of the shredded cheese on top. Set up the oven to broil, bake the creamed spinach for 3 to 5 minutes until golden brown.
This easy and quick Creamed Spinach recipe is a delicious appetizer or side dish in under 20 minutes. Just a few simple ingredients create something creamy, flavorful, and loaded with cheese flavor.
