Prepare the Mushroom Marinade: In a mixing bowl, whisk together olive oil, maple syrup, soy sauce, paprika, garlic powder, and onion powder until smooth.

Marinate the Mushrooms: Slice the shiitake mushrooms and add them to the bowl with the marinade, coating them evenly. Let them marinate for about 10–15 minutes.

Roast the Mushrooms: Spread the marinated mushrooms in a single layer on a greased baking dish and roast at 400°F (200°C) for 25–30 minutes.

Prepare the Miso Sauce: In another bowl, combine white miso paste, peanut butter, toasted sesame oil, chili garlic sauce, soy sauce, maple syrup, rice vinegar, and minced garlic. Whisk until creamy.

Cook the Noodles: Cook the chosen noodles according to package instructions, typically 4–6 minutes, then drain and rinse under cold water.

Combine Noodles and Sauce: In a large bowl, add the cooked noodles and pour in the miso sauce, tossing until thoroughly coated.

Add Edamame and Mushrooms: Add roasted mushrooms and cooked shelled edamame to the noodles and gently fold together.

Serve and Garnish: Divide among serving plates, topping with sliced radish and chopped green onions or Thai basil.
