These mushroom sloppy joes are a flavorful vegetarian take on the ol’ classic dinner sandwich. The meatless mushroom and walnut filling is piled high on a burger bun and then topped with a crunchy slaw and spicy chipotle aioli. They’re sweet, smoky, and saucy, and ready in just 40 minutes!
Whether sloppy joes were a childhood favorite or not, these grown-up vegetarian mushroom sloppy joes are easy to fall in love with. The filling is hearty and satisfying, made with mushrooms and walnuts simmered in an umami-rich sauce that delivers big flavor in every bite.
I like to serve them piled onto soft buns with a simple crunchy slaw and a generous swipe of spicy chipotle aioli. It’s a messy, punchy, totally satisfying meal that feels nostalgic and fresh all at once.
Ingredient notes
Here’s what you need to make the hearty meatless mushroom & walnut filling:
- Mushrooms : we use a simple mix of button and cremini mushrooms, but feel free to use other varieties such as king trumpet or oyster mushrooms if they are available to you.
- Tomato paste : we let the tomato paste caramelize in the pan, which adds a ton of flavor.
- Light beer : a light beer such as a lager adds depth of flavor and a hint of sweetness while replacing the liquid from traditionally used canned tomatoes.
- Chipotle peppers in adobo : chipotle peppers in adobo are spicy and distinctly smoky with an underlying sweetness. Find them in cans or jars with the Mexican products at your grocery store.
Other ingredients you need are vegetable oil, onions, garlic, walnuts, Worcestershire sauce, chili powder, sea salt, and your favorite hamburger buns.
Sloppy joe toppings
Two things not to miss about these vegetarian sloppy joes are the easy-to-make slaw which adds a fresh crunch, and the aioli for another bold layer of flavor.
- To make the slaw , you just need purple cabbage, carrot, red onion, cilantro, and drizzle of olive oil.
- The easy 4-ingredient chipotle aioli is just a mix of mayonnaise (vegan if needed), chipotle peppers in adobo, fresh lime juice, and sea salt.
What to serve with mushroom sloppy joes

Can I make these ahead of time?
Yes! You can prepare all the components of these sloppy joes 1-2 days ahead of time. Simply reheat the filling on the stove with a splash of water when you’re ready to serve them.
How long does the filling keep in the fridge?
Store any leftover filling in an airtight container in the fridge for 3-4 days.
Can I freeze the filling?
You bet! The filling freezes well, making this recipe great for batch meal-prepping. Store it in an airtight container or resealable freezer bag for up to 3 months.
