Sloppy Joe Casserole


We love everything sloppy joes in our house! They have been requested for birthday celebrations, parties and of course, weeknight dinner.  My heart jumps when I discover a new variation of a old family favorite!

I’ve already added it to our family dinner favorites list and I know you’ll be doing the same as soon as you make it!




  • Super easy casserole recipe.
  • Ingredients that you probably have in your pantry.
  • Great make ahead or freezer meal.
  • Less dishes!



  • BUNS: I would normally use like a Hawaiian buns but my grocery store was out of them. Darn Covid! So I used brioche mini buns that were so good but use whatever bun you can find right now!
  • CORN: A delicious, simple addition that I sometimes like to add is a bag of frozen corn or cauliflower for a bit of crunch! This is an optional addition to your casserole. Plus a great way to hide veggies from your kids!





  • To Store: Store any leftovers in an airtight container in the fridge for up to 3-4 days.
  • To Freeze: Sloppy joe casserole makes for a great freezer meal, and can be stored for up to 3 months.
