When I first experimented with Mushroom Patty Sliders, I was surprised at how easily they came together and how flavorful they turned out. I used a mix of cremini and portobello mushrooms to give the patties a complex texture and taste. To bind everything, a bit of breadcrumbs and egg works perfectly, and this method ensures the patties hold their shape while cooking.

One essential tip I discovered is to cook the mushrooms until they release their moisture and become deeply browned. This step enhances their flavor significantly, making your sliders incredibly savory and satisfying. Pair these with a crispy lettuce leaf and your favorite toppings for that extra touch.

Perfecting the Mushroom Patty Texture

Achieving the ideal texture for your mushroom patties is crucial for a satisfying bite. When cooking the mushrooms, ensure they are well-browned; this not only enhances the flavor but also helps remove excess moisture, preventing sogginess in the patties. Aim for a golden-brown color, which usually takes about 8–10 minutes over medium heat. If your mushrooms release too much water, extend the cooking time slightly until the liquid has evaporated.

Another key aspect is the binding agent. The egg in your mixture is essential to hold everything together, but the breadcrumbs play a vital role in absorbing any moisture. For a gluten-free option, consider using crushed gluten-free crackers or ground oats as a substitute for traditional breadcrumbs. This will still lend a pleasant texture without sacrificing flavor.

Flavoring Your Sliders

While the mushrooms offer a rich, earthy profile, the addition of Parmesan cheese contributes a subtle nutty flavor that enhances the umami character of the patties. Freshly grated cheese works best as it melts and binds better than pre-grated varieties. If you're looking for a dairy-free alternative, nutritional yeast can lend a similar cheesy flavor without the milk.

Don’t underestimate the impact of seasoning. A dash of soy sauce brings depth and a hint of saltiness to the mix, so taste your patty mixture before cooking. Adjust salt and pepper to your preference, but remember, you can always add more later, while removing it is more challenging after cooking.

Customizing and Serving Your Sliders

These mushroom patties are incredibly versatile. Feel free to experiment with various toppings to cater to different tastes. Try adding slices of avocado for creaminess, or pickled onions to introduce a tangy contrast. If you’re in the mood for a spicy kick, a jalapeño aioli or a dash of sriracha can elevate the flavor profile.

For meal prepping, the patties can be made ahead and stored in the refrigerator for up to three days. If you'd like to freeze them, shape the patties and place them between sheets of parchment paper before sealing them in an airtight container. They can last for up to three months in the freezer. When ready to enjoy, simply thaw in the refrigerator overnight and cook as directed.

1 clove garlic, minced
1/4 cup grated Parmesan cheese

Instructions

Follow these steps to create your Mushroom Patty Sliders:

Prepare the Mushrooms

Heat olive oil in a skillet over medium heat. Add the chopped mushrooms and garlic, cooking until the mushrooms are browned and any moisture has evaporated, about 8–10 minutes. Let cool slightly.

Make the Patty Mixture

In a bowl, combine the cooked mushrooms, breadcrumbs, egg, Parmesan, soy sauce, salt, and pepper. Mix until well combined.

Form and Cook the Patties

Shape the mixture into 4 even patties. In the same skillet, add a bit more olive oil if needed. Cook the patties over medium heat for about 5 minutes on each side, until golden brown.

Assemble the Sliders

Place each patty on a mini bun, top with lettuce, tomato slices, and any other desired toppings. Serve warm and enjoy!

Once assembled, enjoy your sliders immediately while they’re warm and flavorful!

Pro Tips

For added flavor, try mixing in some chopped herbs like parsley or basil into the patty mixture. Additionally, allowing the patties to chill in the fridge for 15 minutes before cooking can help them hold their shape better.

Storing Leftovers

If you have any leftover patties, they can be stored in an airtight container in the refrigerator for up to three days. Reheat them in a skillet over medium heat for 3–5 minutes on each side until heated through, or pop them in the microwave for about 1-2 minutes, although this may slightly change their texture.

For longer-term storage, consider freezing the cooked patties. Let them cool completely before placing them in a freezer-safe container with parchment paper between layers to prevent sticking. When you're ready to enjoy them, simply thaw overnight in the fridge and reheat as desired.

Scaling the Recipe

Easily double or triple this recipe for larger gatherings or meal prep. When scaling, use the same proportions for ingredients, maintaining the ratios. However, remember to increase cooking time slightly when frying multiple patties, as the temperature of the skillet may drop with more patties at once. Cook in batches if necessary, allowing for even browning.

Consider varying the sizes of the patties as well. For smaller sliders, simply shape the mixture into smaller rounds, adjusting the cooking time to 3-4 minutes per side. Larger patties can be made for traditional burger setups, expanding the range of serving styles.
