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.

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.
