What Are Sloppy Joe Stuffed Portobello Mushrooms?
This dish takes traditional sloppy Joe filling, seasoned ground beef in a sweet and tangy tomato-based sauce and spoons it into roasted portobello mushroom caps instead of sandwich buns.
The mushrooms act as natural “bowls,” soaking up flavor while adding a rich, earthy depth. It’s a gluten-free, low-carb, and keto-friendly way to enjoy a nostalgic favorite.
This meal will get the kids to sit down and enjoy family dinner. My daughter is going through a “I don’t like mushrooms” phase. But, she loved these Italian Sloppy Joe Stuffed Portobello Mushrooms!
Why You’ll Love These Sloppy Joes
- Low-carb & keto-friendly
- Hearty and satisfying
- Ready in about 30 minutes
- High-protein meal
- Naturally gluten-free
Typically I like to add Tex Mex flair to my sloppy joe creations. But like I said, I’m trying to expand my dinner menu. So I added some Italian flavor to this dish. Plus, there is some spinach hiding in there. The kids will never know. Heehee.
Tips for Success
- Pre-bake mushrooms to prevent sogginess.
- Don’t skip draining the meat.
- Simmer the sauce until thick — excess liquid can make the mushrooms watery.
- Use freshly shredded cheese for best melting texture.
Sloppy Joe Stuffed Portobello Mushrooms offer all the nostalgic comfort of a traditional sloppy joe without the bun. They’re hearty, flavorful, and perfect for anyone looking for a lighter or low-carb option.

Loved the Sloppy Joe Jalopie!!!
I want to try their recipe for the chicken strips with zesty dipping sauce. I always viewed Manwich as being one-dimensional, but a look through their recipes shows me that isn’t the case by a long shot

The Creamy Sloppy Joe bites really caught my eye. It sounds like something my husband will love. We’re empty nesters and feeding the two of us is sometimes a hard task. I know that sounds silly, but he won’t eat leftovers but I’ll take them to work. So finding something new to prepare each night is getting so rough. I’m definitely going to try your stuffed portabello mushrooms.
