Mushroom Preparation

• Mushrooms: You’ll want to choose large mushrooms like portobello or BBQ flat mushrooms, as they’re slightly larger than most burger buns and can hold up well in a burger. Their meaty texture makes them an excellent choice for a vegetarian alternative to beef.
• Seasoning & Butter: The garlic butter is what makes these mushrooms rich and savory. You’ll use unsalted butter, fresh garlic, salt, and pepper to make sure every bite bursts with flavor.
• Cheese: Swiss cheese is the star here, adding a creamy, melty element to the mushrooms. You can, however, substitute it with your favorite cheese, such as cheddar or gouda, for a different twist.

Onion Preparation

• Onions: Sautéed onions are the perfect topping to complement the mushrooms. The sweetness from the onions will balance the savory flavors in the garlic butter and cheese.
• Seasoning: A pinch of salt and pepper are all you need to season the onions, letting their natural sweetness shine through as they caramelize.

Pink Burger Sauce

• Sauce Ingredients: The homemade pink sauce is made by combining mayonnaise (or sour cream if you prefer a creamier texture), ketchup, and Sriracha for a spicy kick. This sauce is what ties everything together with its tangy and slightly spicy flavor.

Burger Assembly

• Buns: You’ll need 4 burger buns, and brioche buns are preferred for their soft, slightly sweet texture. They’re the ideal base for this mushroom burger, providing a gentle contrast to the savory toppings.
• Fresh Vegetables: Crisp lettuce and fresh tomato slices are the perfect additions for some crunch and freshness.

Optional Sides

• Side Suggestions: While your burger is the star, pairing it with crispy French fries or baked potato wedges will make for a well-rounded meal.

Step-by-Step Instructions for Crafting the Perfect Savory Mushroom Burger

Now that you have all your ingredients ready, let’s break down the steps to create the ultimate savory mushroom burger. From prepping the mushrooms to assembling the burger, every detail counts in ensuring your burger is packed with flavor.

Preparing the Mushrooms

1. Brush the Mushrooms: Start by brushing the smooth side of the mushrooms with your homemade garlic butter. Make sure you cover them generously for maximum flavor.
2. Roast the Mushrooms: Preheat your oven to 450°F (or 425°F if you’re using a convection fan setting). Place the mushrooms on a baking sheet with the gills facing up and roast them for 25 minutes. After 25 minutes, flip the mushrooms over, basting them with the juices on the tray, and roast for another 10 minutes or until they are tender and juicy.

Caramelizing the Onions

1. Sauté the Onions: While the mushrooms are roasting, heat 1 tablespoon of olive oil in a large skillet over high heat. Add your onion rings and cook them for 5-7 minutes, stirring occasionally, until they soften and turn a beautiful golden brown. This caramelization process enhances the natural sweetness of the onions.
2. Season the Onions: Add a pinch of salt and pepper to the onions while they cook, bringing out the savory flavors that will perfectly balance the mushrooms and cheese.

Melting the Swiss Cheese

1. Top the Mushrooms with Cheese: Once the mushrooms are roasted to perfection, place a slice of Swiss cheese on top of each one.
2. Melt the Cheese: Return the mushrooms to the oven for 3 more minutes, or until the cheese has melted and is oozing beautifully over the mushrooms.

Toasting the Buns

1. Toast the Buns: Split your brioche buns in half and place them in the oven to toast for a few minutes until they’re golden brown. This step adds a bit of crunch and prevents the buns from becoming soggy when the juicy mushrooms and sauce are added.

Crafting the Pink Sauce

1. Make the Sauce: In a small bowl, combine 2/3 cup of mayonnaise, 2 tablespoons of ketchup, and 1 to 3 teaspoons of Sriracha (depending on your spice preference). Stir until the sauce is smooth and well mixed. Set it aside for assembly.

Assembling the Burger

1. Spread the Pink Sauce: Spread a generous amount of the pink sauce on the bottom half of each toasted bun. This creamy sauce will add a tangy, spicy kick that enhances the richness of the mushrooms and cheese.
2. Layer the Ingredients: On top of the pink sauce, layer a few fresh lettuce leaves and sliced tomatoes for a refreshing crunch. Then, place the roasted mushroom with melted cheese on top.
3. Add the Caramelized Onions: Top the cheese-covered mushrooms with the sweet, caramelized onions.
4. Finish the Burger: Spread a little more pink sauce on the top half of the bun and place it on top of the burger, pressing gently to hold everything together.

Tips for a Perfect Savory Mushroom Burger

Choosing the Right Mushrooms

The type of mushrooms you choose can make a big difference in the final flavor and texture of your burger. Portobello mushrooms are a popular choice for their large size and meaty texture, but BBQ flat mushrooms are also a great option for their mild flavor and slightly firmer texture. Whichever you choose, just make sure they’re large enough to hold up as a burger patty.

Customizing the Pink Sauce

Feel free to experiment with the pink sauce to make it your own. For a creamier texture, you can substitute sour cream for mayonnaise. You can also adjust the amount of Sriracha to suit your spice tolerance. If you’re not a fan of spicy sauces, try adding a little Dijon mustard or lemon juice for a tangy alternative.

Serving Suggestions

To complete the meal, pair your savory mushroom burger with crispy French fries or baked potato wedges. The crunchy sides will complement the soft, juicy burger and enhance the overall experience. You can also serve a refreshing side salad for some added freshness.
