Hey cousins! So many of you have been asking for slow cooker recipes, so I’ll continue pumping them out. In this post I’m going to show you how I make my slow cooker smothered roast.

This smothered beef roast is fall-apart tender and seasoned to perfection

This recipe is quite easy. I use use a package of onion mushroom soup mix, however regular onion soup mix is okay as well!

At the end of this recipe I add heavy cream to make the gravy nice and creamy. If you’re not a fan of adding cream to your gravy, that step can be omitted.
