Listen, as a mom for over a decade, I know how important quick, easy meals are and this slow cooker sloppy joes recipe hits all the right notes.
Plus, what kids don’t love sloppy joes! You’re literally giving them a reason to have a messy dinner!
Sloppy joes themselves are really easy to make; however, these slow cooker vegan sloppy joes are even easier. Literally we are just going to throw most of our ingredients together in a slow cooker and then the recipe is good to go.
Lentils are a great meat replacement because they are filling and take on somewhat of a similar texture in that they are hearty.

Slow Cooker Sloppy Joes Ingredients:
Below are notes about the ingredients before we get into the full recipe located lower in this post on how to make this easy crockpot vegan sloppy joes:
- lentils – you want to use green or brown lentils for this recipe. Red lentils break down too much so they won’t be great for this recipe
- onions, garlic, and bell peppers – These three are our aromatics of the dish and create the base layer of flavor that is perfect is giving this knock off burger lots of flavor.
- seasonings- We have a unique blend that we highly suggest not altering. Obviously, you can taste and adjust as needed, but we definitely recommend starting with the base we suggest
- diced tomatoes – We love fire roasted tomatoes in this dish. Adding the tomatoes into the lentils when it first start cooking allowing for the flavor to develop
- soy sauce and liquid smoke – the soy sauce gives us an umami flavor and the liquid smoke helps the recipe seem like it’s been out under a smoker for hours
- ketchup, yellow mustard, brown sugar – these three are the base of any sloppy joe recipe and give that sloppy yet sweet
SUBSTITUTIONS AND VARIATIONS:
- lentils – you could sub the dried lentils for canned lentils. If you do this, reduce the stock to ¾ cup.
- diced tomatoes – While we love fire roasted tomatoes in this dish, any diced tomatoes would work
- soy sauce and liquid smoke – soy sauce can be swapped with coconut or liquid aminos if needed
- yellow mustard – try swapped the yellow mustard for dijon for a little different taste
- brown sugar – replace with coconut sugar, date sugar or a syrup like maple syrup
