Ingredients
Instructions
- Preheat oven to 425°F (220°C) and position rack in top third. Wash and dry produce. Cut potatoes into ½-inch-thick wedges. Trim and thinly slice scallions, separating whites from greens; roughly chop whites. Quarter lemon. Trim and halve mushrooms (quarter any large ones).
- Toss potato wedges on a baking sheet with a drizzle of oil, half the Old Bay seasoning, salt and pepper. Roast on top rack, flipping halfway, until browned and tender, 20-25 minutes.
- In a medium bowl, combine shredded cabbage, scallion greens, sour cream, sugar and juice from one lemon wedge. Season with salt and pepper. Set slaw aside.
- In another medium bowl, mix mayonnaise, Dijon mustard, scallion whites, juice from one lemon wedge and hot sauce to taste. Set remoulade aside.
- In a third bowl, whisk together tempura batter mix, garlic powder, remaining Old Bay and ⅓ cup cold water (add more water 1 tbsp at a time if too thick) until smooth like pancake batter. Stir in mushrooms until fully coated.
- Heat a ⅓-inch layer of oil in a large pan over medium-high heat. When oil is hot (a drop of batter sizzles), add coated mushrooms in a single layer (work in batches if needed). Cook until golden brown, 3-4 minutes per side. Transfer to a paper-towel-lined plate and season with salt.
- While mushrooms cook, slice baguettes lengthwise without cutting all the way through. Toast cut sides up directly on oven rack or a baking sheet until golden, 3-5 minutes.
- Spread remoulade on cut sides of baguettes. Fill with mushrooms, dill pickles and slaw. Serve sandwiches with fries, remaining slaw, remoulade and lemon wedges on the side.
Recipe Tips
For extra crispy mushrooms, make sure the oil is hot enough before adding the batter-coated mushrooms.
If the batter thickens while standing, thin with a little cold water.
Serve fries with ketchup or malt vinegar if desired.
FAQ
Can I use a different type of mushroom?
Yes, cremini or oyster mushrooms work well, but button mushrooms are recommended for their mild flavor and firm texture.
How do I make the remoulade spicier?
Add more hot sauce or a pinch of cayenne pepper to the mayonnaise mixture.
Can I make these gluten-free?
Use a gluten-free tempura batter mix and gluten-free baguettes. Ensure all other ingredients are gluten-free.
