Instructions

1. Preheat oven to 425°F. Cut potatoes into wedges. Toss with 2 tsp oil, salt, and pepper. Spread on a baking sheet and bake for 20-25 minutes until golden and crispy.
2. While potatoes bake, slice mushrooms and onion. Heat 2 tsp oil in a skillet over medium-high heat. Add mushrooms and onion, season with salt and pepper. Cook until softened and browned, about 5-7 minutes. Stir in mushroom stock concentrate and cook 1 minute more. Remove from heat.
3. In a small bowl, mix mayonnaise and garlic powder to make garlic aioli. Set aside.
4. Lay sourdough slices on a work surface. Spread Dijon mustard on two slices. Top each with Swiss cheese, mushroom-onion mixture, Monterey Jack cheese, and remaining bread slices.
5. Melt 1 tbsp butter in a large skillet or panini press over medium heat. Place sandwiches in skillet (work in batches if needed). Cook until bread is golden and cheese melts, about 3-4 minutes per side. Add remaining butter as needed.
6. Serve panini with potato wedges and garlic aioli for dipping.
