Meet Sloppy Jane: a lighter, nutrient-dense take on the classic Sloppy Joe. These Sloppy Janes swap a bread roll for roasted sweet potatoes and deliver all the savory, slightly spicy flavors you love in a classic sloppy sandwich—while remaining Whole30-friendly, paleo, gluten-free, grain-free, and dairy-free. They’re easy to prepare, family-approved, and perfect for weeknight dinners or casual gatherings.

To make Sloppy Janes, roast whole sweet potatoes until tender, then stuff them with a well-seasoned ground beef mixture made with onions, bell pepper, garlic, tomato paste, mustard, and coconut aminos. Most of the cooking time is hands-off while the potatoes roast, making this dish low-stress and ideal for busy evenings. The result is a comforting, satisfying main course that offers more nutrients and fiber than a traditional sandwich—plus bright flavor and a pleasing contrast of textures.
These are great for feeding a crowd. Roast extra potatoes and double the beef mixture for easy meal prep or leftovers that reheat well. Serve with a simple green salad or steamed vegetables for a balanced plate.
Ingredients
- For the sweet potatoes:
- 4 medium sweet potatoes
- 2 tablespoons avocado oil
- 1/2 teaspoon kosher salt
- For the Sloppy Jane mixture:
- 2 tablespoons avocado oil
- 1 cup finely diced yellow onion (about 1/2 large onion)
- 1 cup finely diced green bell pepper (about 1 pepper)
- 2 garlic cloves, minced
- 1 pound ground beef
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon chili powder
- 2 tablespoons tomato paste
- 1 tablespoon yellow mustard (or 1 teaspoon dry mustard powder)
- 1/4 cup coconut aminos (or soy sauce/tamari as a non–Whole30 substitute)
Step-by-Step
Step one: Preheat the oven
Preheat your oven to 400°F (about 200°C). Position a rack in the center so the sweet potatoes roast evenly.
Step two: Prep the sweet potatoes
Scrub the sweet potatoes well and pat them dry. Place them on a baking sheet and pierce each potato about six times with a fork. Drizzle with avocado oil and rub it over each potato so they’re evenly coated, then sprinkle with kosher salt.
Step three: Bake the sweet potatoes
Roast the potatoes in the preheated oven until tender when pierced with a knife, about 45 minutes depending on size. Remove and let cool slightly so they’re easy to handle.
Step four: Start the Sloppy Jane mixture
While the potatoes roast, heat 2 tablespoons of avocado oil in a large skillet over medium-high heat. Add the diced onion, green bell pepper, and minced garlic. Sauté, stirring occasionally, until the vegetables soften, about 3 minutes.
Step five: Add the ground beef
Add the ground beef and cook, breaking it up with a spatula, until it’s cooked through and no pink remains, about 6–8 minutes. If there’s excess fat, drain it from the pan and reduce the heat to medium-low.

Step six: Finish the Sloppy Jane mixture
Stir in the salt, black pepper, chili powder, tomato paste, yellow mustard, and coconut aminos. Cook briefly to meld the flavors, then remove from heat, cover, and keep warm until the sweet potatoes are ready.
Step seven: Finish and serve
When the potatoes are cool enough to handle, slice a lengthwise slit across the top of each one and use a fork to fluff the flesh. Spoon the warm Sloppy Jane mixture over each potato, garnish if desired (fresh cilantro, sliced green onions, or avocado are nice options), and serve immediately.

Recipe FAQs
Can I add other vegetables to the Sloppy Jane mixture?
Yes—add finely diced carrots, zucchini, corn, or a handful of spinach. If using firmer vegetables like carrots or zucchini, sauté them with the onions and peppers until tender before adding the beef.
I don’t have yellow mustard—can I use dry mustard?
Yes. Substitute about 1 teaspoon of dry mustard powder for 1 tablespoon of prepared yellow mustard. Taste and adjust as needed.
How do Sloppy Janes differ from sloppy joes?
Sloppy Janes keep the core savory, tangy flavor of a sloppy joe but serve it in a roasted sweet potato instead of a bun. That swap increases fiber and nutrients while reducing refined carbs.
What can I use instead of coconut aminos?
Soy sauce or tamari make good substitutes but are not Whole30 compliant. Reduce the amount slightly if using a saltier soy sauce to keep sodium in check.
