🥘 Ingredients Needed
- cauliflower rice - contributes to this recipe's nutritional factor, but doesn't alter the flavor much.
- butternut squash - just like the cauliflower rice, the squash adds some vitamins to your sloppy Joe sliders without compromising that classic taste.
- extra lean ground beef - your typical sloppy Joe starting point.
- yellow mustard - gives your sliders just a little bit of bite.
- ketchup - what better to pair with mustard than ketchup?
- brown sugar - with all of the salty and savory ingredients, this will give your dish a bit of sweetness and balance out the flavor profile.
- garlic powder - helps cover up the mild flavors from the cauliflower and squash and trick your taste buds into forgetting they're there!
- salt and pepper - brings all of the flavors together.
- Pour some olive oil into a skillet and heat it over medium-high heat. Add your cauliflower and squash, then cook until they're nice and soft.
- Add the ground beef and cook until it's brown.
- Stir in the remaining ingredients, then simmer for about 5 minutes, until everything is combined.
- Serve on slider rolls and enjoy!
Allow the beef mixture to cool to room temperature, then transfer to an airtight container and store in the fridge for 3-4 days. You can also store the beef in the freezer, where it should keep for up to 6 months.
There are two possibilities here: first, you could transfer your beef mixture to a microwave safe bowl and cover the top with plastic, leaving a space oven to vent, and microwave for about 2 minutes. Then give it a good stir, and continue in 30-second intervals if it's not hot enough.
Or, you could heat over the stovetop. Place the beef in a pot with about 1/4 cup of water, then heat on low with the lid on, stirring occasionally, until the beef is all heated through.
From frozen, just allow the beef to thaw before following either of the methods above.
Yes! If you'd like to prepare the filling ahead of time, just follow the instructions above for reheating when the time comes. Of course, you won't want to divide the mixture onto the slider rolls until it's time to actually serve!
No, the type of roll you serve is completely up to you! But isn't there something so cute about the little mini sandwiches?
💭 Top Tips
- If your beef isn't very lean, you may want to cook it in a separate skillet, drain the grease, and then combine with the veggies.
- To really elevate these sloppy Joe sliders, try toasting the rolls first.
How to buy the best ground beef:
- If you can, look for beef that's been ground in-store on the same day you're buying.
- Even better, if you can request for a butcher to grind it for you on the spot, you'll know you're getting the freshest product available.
- 80/20 ground beef is widely considered the perfect blend for things like burgers. It may seem like this is a lot of fat, but most of it ends up rendering out during cooking. For this recipe, you could get away with something that's a bit on the leaner side.
How to buy the best butternut squash:
- You'll want a squash that feels a bit heavy for its size. Firmness in the stem tends to mean that the squash will hold up longer, which can be useful if you're not planning on using it immediately.
- A fat neck and small bulb is a good indicator of a small seed cavity, which means more squash meat to work with. Avoid a squash that has soft spots or obvious molding.
- The skin of the squash should be fairly hard and free of blemishes, though it's normal for a pale spot to form that tells you where the squash was resting out in the field.
- In terms of color, your squash should have a nice, deep hue to it. For butternut squash, look for a dark beige. Green spots or streaks tend to mean that the squash isn't fully ripe yet.
- No time to deal with a fresh butternut squash? Buy frozen diced squash. That's actually wht I recommend for this recipe. It works really well!
- Instead of beef, you can use ground chicken or turkey! The flavor will be slightly different, but with all of the seasonings and condiments, it will hardly be noticeable.
- Top each of your sloppy Joe sliders with a little piece of cheese. American, cheddar, or pepper jack would be delicious, but you could experiment with whatever you like best!
- For a Southwestern flair, stir in some salsa and black beans into the beef mixture.
- If you're craving something with an Asian twist, omit the ketchup and mustard and substitute hoisin and ground ginger. Then garnish with cucumber, cilantro, and shredded carrot.
- You can turn these into tiny Philly Cheesesteaks by adding chopped onions, mushrooms, and green peppers. Top with Provolone cheese.
