I love making these vegetarian sliders because they are simple, tasty, and perfect for sharing with friends or family. They’re a fun way to enjoy something healthy without missing out on flavor. I can’t wait for you to try them and see how easy it is to make a delicious meal from just a few ingredients.
Most of the ingredients in this recipe are pretty common, but if you don’t usually keep black beans at home, you might want to pick up a can or some cooked beans from the store. Bread crumbs can sometimes be found near the baking supplies or in the bread aisle. If you don’t have cumin or paprika, those spices add a lot of flavor, so it’s worth grabbing them too—they’re usually in the spice section.
Ingredients For Vegetarian Sliders Recipe
Black beans: mashed black beans give the sliders a soft texture and add protein.
Bread crumbs: help hold the patties together so they don’t fall apart while cooking.
Onion: finely chopped onion adds a bit of crunch and a mild, sweet flavor.
Garlic: minced garlic brings a nice, savory kick to the patties.
Olive oil: used for cooking the patties and adds a subtle richness.
Cumin: a warm spice that gives the sliders a slightly smoky taste.
Paprika: adds color and a mild peppery flavor.
Salt: enhances all the flavors in the patties.
Black pepper: adds a little bit of heat and depth.
Slider buns: small buns perfect for holding the patties and toppings.
Technique Tip for This Recipe
One of the most important steps in this Vegetarian Sliders Recipe is chopping the onion finely. When you chop an onion into tiny pieces, it mixes better with the other ingredients and helps the patties hold together without big chunks. Here’s a simple way to do it:
- Peel the onion and cut it in half from top to bottom.
- Place one half flat side down on the cutting board.
- Make several horizontal cuts into the onion, but don’t cut all the way through the root end.
- Then, make vertical cuts from top to bottom, again stopping before the root.
- Finally, slice across the onion to create small, even pieces.
Doing it this way keeps the onion pieces small and even, so they cook well and don’t overpower the other flavors. Plus, finely chopped onion spreads throughout the black beans and spices in the patties, giving each bite a little bit of tasty onion without being too strong.
When I first tried this, I didn’t chop the onion finely enough, and some bites had big chunks that made the patties fall apart or taste too sharp. After practicing this method, the patties stayed together better and tasted smoother. Also, if you’re in a hurry, you can use a food processor to pulse the onion a few times, but be careful not to turn it into mush!
Taking a little extra time to chop the onion well really makes a difference in how your vegetarian sliders turn out. It’s a small step that helps everything cook evenly and taste just right.

How to Store / Freeze Your Sliders
- Allow the patties to cool completely before storing. This prevents condensation, which can make them soggy.
- Place the cooled patties in an airtight container. If stacking, use parchment paper between layers to avoid sticking.
- Store the container in the refrigerator for up to 3-4 days. This keeps the patties fresh and ready for a quick meal.
- For longer storage, freeze the patties. Lay them out on a baking sheet lined with parchment paper and freeze until solid.
- Once frozen, transfer the patties to a freezer-safe bag or container. Label with the date to keep track of freshness.
- Frozen patties can be stored for up to 2-3 months. This ensures you always have a quick and healthy meal option on hand.
- To reheat, thaw the patties in the refrigerator overnight. This helps maintain their texture and flavor.
- Heat a skillet over medium heat and add a bit of olive oil. Cook the thawed patties for 2-3 minutes on each side until heated through.
- Alternatively, reheat in the oven at 350°F (175°C) for about 10-15 minutes. This method is great for retaining the patties' crispiness.
- Enjoy your vegetarian sliders with fresh slider buns and your favorite toppings for a delicious meal.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the vegetarian sliders on a baking sheet lined with parchment paper. Cover them with aluminum foil to prevent drying out. Heat for about 10-15 minutes or until warmed through.
For a quicker method, use a microwave. Place the sliders on a microwave-safe plate. Cover them with a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure they are evenly heated.
If you prefer a crispy exterior, reheat the sliders in a skillet. Heat a bit of olive oil over medium heat. Add the patties and cook for about 2-3 minutes on each side until they are heated through and regain some of their original crispiness.
For an air fryer method, preheat the air fryer to 350°F (175°C). Place the sliders in the basket in a single layer. Heat for about 5-7 minutes, shaking the basket halfway through to ensure even heating.
If you have a toaster oven, preheat it to 350°F (175°C). Place the sliders on a baking tray and cover with aluminum foil. Heat for about 10 minutes or until they are warmed through.
