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
Frequently Asked Questions:

My family loved this recipe! Thank you for sharing. I didn’t have liquid smoke on hand so I used a canned chipotle pepper and a little of the sauce they’re packed in. Delicious!
We’re thrilled to hear that your family enjoyed the recipe. Your substitution of using a canned chipotle pepper with its sauce instead of liquid smoke sounds absolutely delicious, what a creative solution! We appreciate you taking the time to share your feedback and are so glad the recipe worked out well for you.
Too sweet for our taste!
Would try again without added sugar, plain tomato paste instead of ketchup, 1/4 cup more lentils and a bit less liquid overall. 😉
Thanks for your feedback
We love this recipe, and I make it again and again. I would not change a thing.
so glad you love it!
Thanks so much for this recipe!!! The sloppy Joe patties were delicious! Will definitely have this as a go to for different dinner nights. 🙏💯
So glad you enjoyed it
My house smells great. I doubled the recipe and it is still very liquidy after 2 hours on high. If I need to can I just continue cooking it until it thickens, I don’t think 3 hours will be enough time. I need it for tomorrow so I have all the time in the world.
It was an epic fail for me too. They were in the crock pot for 6 hours on high last night. Tonight they are on the stove. Lentils still not cooked. Flavor might be ok, but haven’t added ketchup, etc. Will add less of that and the brown sugar and hope for the best.
Did the liquid run out on high for that long? They should be cooked well after 6 hours. What type of lentils did you use?
We love this recipe, it’s become a regular item on our meal rotation.
We’re making it this week for our picky 4-yr-old grandson, I’m betting he will approve. Thanks for all the great recipes you post!
I bet so too!
