Thanks to fresh green beans, an easy homemade cream sauce and crispy onion topping, this green bean casserole recipe is healthier and more delicious than traditional recipes that use canned soup, beans and onions. Plus, the slow cooker saves you time cooking at the stove. Make sure to use fresh green beans, as frozen green beans will become mushy.

Asparagus Casserole

View Recipe

In this baked asparagus side dish recipe, we smother tender-crisp asparagus spears with a creamy cheese sauce and top the casserole with crispy panko breadcrumbs. Blanching the asparagus first in boiling water helps preserve its vibrant green color. Medium-thick asparagus spears work best for this recipe. If your asparagus spears are very thick, they may need a longer time in the oven.
