When I first experimented with mushroom patties, I was surprised by how versatile they can be. I tried various types of mushrooms, and I found that a mix of cremini and shiitake adds a rich umami flavor that elevates the patty. I also discovered that adding breadcrumbs helps create a more cohesive texture, making it easy to form them into sliders.

One tip I’d suggest is to grill the sliders instead of frying them. This method enhances their smoky flavor and retains moisture, resulting in an incredibly satisfying bite. I love serving them on mini buns with a fresh herb aioli for a delightful finish!

Understanding the Ingredients

The mushrooms are the star of this dish, and using a blend of cremini and shiitake enhances the umami flavor and adds depth. Cremini mushrooms provide a robust taste, while shiitake introduces a slightly smoky note. When chopping, aim for a uniform size to ensure even cooking. If you prefer, you can substitute with portobello mushrooms for a meatier texture, but keep in mind that their moisture content is higher, so adjust the breadcrumbs accordingly.

Parmesan cheese not only contributes a savory profile but also aids in binding the patties together. You can swap it with nutritional yeast for a dairy-free option, providing a cheesy flavor without the lactose. Breadcrumbs are essential for achieving the right texture—use panko for extra crunch or whole wheat for a nuttier taste. Just remember to lightly toast them if you want a deeper flavor before mixing into your patty batter.

Perfecting the Cooking Process

When sautéing the mushroom mixture, be mindful of the heat level. Medium heat allows the onions and garlic to soften without browning too quickly. Cook the mushrooms until they are browned and have released most of their moisture, which is about 5–7 minutes. This step is crucial as it concentrates their flavors and ensures the patties don’t become soggy later due to excess moisture.

While grilling the patties, keep an eye on the edges; they should turn golden brown and crispy. Use a spatula to carefully flip them to maintain their shape. If the patties seem to crumble, consider adding a bit more binding agent like breadcrumbs or allow them to chill slightly before grilling to firm up the mixture.

Ingredients

For the Mushroom Patties

2 cups chopped mushrooms (cremini and shiitake)
1/2 cup breadcrumbs
1/4 cup grated Parmesan cheese
1/4 cup chopped onion
2 cloves garlic, minced
1 teaspoon soy sauce
1 teaspoon olive oil
1 teaspoon thyme
Salt and pepper to taste

For Assembly

4 mini slider buns
Lettuce leaves
Tomato slices
Herb aioli (optional)

Instructions

Prepare the Mushroom Mixture

In a skillet over medium heat, heat the olive oil and sauté the onions and garlic until soft. Add the chopped mushrooms and cook for about 5–7 minutes, until they release moisture and reduce in size. Stir in the soy sauce, thyme, salt, and pepper.

Remove from heat and let cool slightly.

Form the Patties

In a mixing bowl, combine the mushroom mixture with breadcrumbs and Parmesan cheese. Mix until well combined. Form the mixture into 4 equal-sized patties.

Grill the Patties

Preheat your grill or a grill pan over medium heat. Cook the patties for about 4-5 minutes on each side until golden brown and heated through.

Assemble the Sliders

Place each mushroom patty on a mini slider bun. Add lettuce and tomato slices. Drizzle with herb aioli if desired. Serve warm.

Pro Tips

For extra flavor, you can try adding different herbs or spices to the mushroom mixture, such as smoked paprika or fresh parsley. Also, letting the patties rest for a few minutes after cooking can help them hold together better during assembly.

Make-Ahead and Storage Tips

These mushroom patties can be made ahead of time, making them a convenient option for parties or meal prep. After forming the patties, you can refrigerate them for up to 24 hours or freeze them. To freeze, lay the patties on a baking sheet lined with parchment paper, freeze until solid, and then transfer to a freezer-safe container. They can be cooked directly from frozen, just add a few extra minutes to the cooking time.

To store leftovers, place the cooked patties in an airtight container in the fridge for up to 3 days. They can be reheated in a skillet on low heat for about 5 minutes on each side, allowing them to regain their crispiness. Alternatively, you can microwave them, but they may lose some texture.

Serving Suggestions and Variations

Try serving the sliders with a variety of toppings to elevate the flavor. Pickled red onions, sliced jalapeños, or avocado can add a punch of freshness and complexity. For a twist, swap out the herb aioli for a spicy chipotle mayo to introduce some heat. If you're serving them at a party, consider offering a make-your-own slider bar with diverse toppings, allowing guests to customize their creations.

For a fun variation, consider adding some finely grated carrots or zucchini to the mushroom mixture, which can increase the veggie content and introduce a new texture. You can also try incorporating different herbs such as basil or parsley for a fresh flavor profile, depending on your preference or what you have on hand.
