A vegetarian (also vegan and gluten-free) version of everyone's favorite messy sandwich!
A mushroom and vegetable version of sloppy Joe\'s served on a bun with the skillet in the background.

I was not a good vegetarian the year that I tried it in high school. I did not have my complete and utter love for vegetables that I have now and I didn't eat any of the good stuff - like hummus or quinoa - that I should have eaten to get a  more well-balanced diet. Oh, and I kind of cut a lot of corners.

Case in point: I went to visit a friend who was in college that year. We hung out, went to a party and came back to her dorm room late, very hungry. She had one of those plug-in cook tops and some chicken noodle soup from a can. She heated it up and I just picked out what I could of the chicken pieces. They were tiny and everywhere and the whole soup was probably infused with chicken. I obviously didn't take the vegetarian thing very seriously.

These days, I eat plenty of meat. Mostly chicken and turkey and seafood and lean pork. But we do like to have a meatless night here and there. And since I love, love, love sloppy Joe's, I wanted to try a meat-free version. So I experimented with this for a bit and finally settled on the recipe below. Except, well… I pretty much always use chicken broth. Instead of vegetable broth. It's what I've always got on hand and ready to go! I'd still make a terrible vegetarian, apparently.

So use whatever broth you have but you gotta try this version of sloppy Joe's. The mushrooms are so hearty and bring so much good flavor, and then combined with the tangy sauce - so much yum. Even the carnivores won't mind tucking into this.

Now, I know it seems like a ton of mushrooms! And it is, but they cook down a lot. It's kinda like spinach that way. You end up with not nearly so much, just all the meaty, umami flavor that mushrooms bring. The mushrooms also give off a lot of moisture as they cook, so you don't have to add much to get this nice and saucy (and sloppy, as they should be!)

So these sandwiches come out vegan, vegetarian and gluten-free (just check your sauce mixes and buy gluten-free versions) - a dinner everyone can enjoy! And if you're worried about a soggy bun, try these tips:
1. Toast the bun. This helps a lot. Even more helpful is...
2. Use mayonnaise on the bottom bun. It creates a fat barrier that prevents the sauce from dripping through and soaking into the bread. My husband requests this every time he orders a burger at a restaurant.
3. Serve it my favorite way - stuffed into a baked potato! I love having my sloppy Joe's in a potato instead of in a sandwich. I always eat the whole potato, so it acts as an edible bowl with the sloppy Joe mix. Delicious.

Whichever way you go, you may need a fork. Messy central!

I hope you enjoy this veggie-fied version of sloppy Joes!

Notes

Don’t like it spicy? Just leave out the jalapeño pepper and skip the hot chili sauce. These will still have tons of great flavor!
Also, if you are a vegetarian, you'll need to use an anchovy-free Worcestershire sauce. Trader Joe's and other retailers carry this and there are also kosher versions that don't have anchovies and would be vegetarian.

    Lol! You are forgiven for being a terrible vegetarian a while back! I was a vegetarian for a couple years and then a pescatarian for over a decade. Culinary school forced me to knock that nonsense off. But im like you, I still eat vegetarian quite often.. and lots of times I cut "vegetarian corners" like using chicken broth #opps! 🙂 These veggie sloppy joes look awesome, girlfriend! Love that they looks so meaty without the meat! #winning! I'll be trying these for sure! Cheers, lovely!

    For what it's worth, most Worcestershire sauce is not vegetarian or vegan; most varieties contain anchovy. You may want to edit your post to suggest a vegetarian version of it, or a substitute!

      Thanks Mandy! That's a good point. (See, I'm still a terrible vegetarian.) I know Trader Joe's and some other retailers offer an anchovy-free Worcestershire sauce and there are also kosher versions that would be vegetarian. I'll update the notes of the recipe to point that out.
