19 - 2 tablespoons melted unsalted butter
20 - 2 tablespoons chopped fresh parsley (optional)

# How to Make:

01 - Preheat oven to 375°F. Lightly grease a 9x13-inch baking dish.
02 - Prepare the wild rice blend according to package directions using vegetable broth or water; set aside once cooked.
03 - Heat olive oil in a large skillet over medium heat. Add chopped onion and cook until translucent, about 3–4 minutes.
04 - Stir in garlic, mushrooms, celery, and carrots. Sauté until mushrooms are tender and vegetables soften, approximately 8–10 minutes.
05 - Add thyme, salt, and black pepper; cook for 1 more minute then remove from heat.
06 - In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1 minute to form a roux.
07 - Gradually whisk in milk and cream. Cook, stirring constantly, until sauce thickens, about 3–4 minutes.
08 - Remove from heat and stir in Parmesan cheese and soy sauce until fully incorporated.
09 - In a large bowl, combine cooked wild rice, sautéed vegetables, and creamy sauce. Mix thoroughly.
10 - Spread the mixture evenly in the prepared baking dish.
11 - Mix panko breadcrumbs with melted butter and chopped parsley. Sprinkle evenly over the casserole. Add shredded cheese if desired.
12 - Bake uncovered for 25–30 minutes until the topping is golden and the casserole bubbles.
13 - Allow to cool for 5 minutes before serving.

# Expert Suggestions:

01 -
  • It tastes like you spent hours cooking when it's actually ready in just over an hour.
  • The creamy sauce clings to every grain of wild rice, making each bite feel indulgent without being heavy.
  • It sits beautifully as a main course or moves to the side of the plate with equal grace.
02 -
  • The soy sauce might seem like an odd addition, but it deepens the umami in a way that makes people taste mushroom flavor they didn't know was there—don't skip it or reduce it.
  • If your sauce breaks or looks lumpy when you add the cream, strain it through a fine sieve and continue; it will smooth out as it heats and blends with everything else.
  • Don't cover the casserole while baking or your topping will steam instead of crisp, and that golden finish is what makes this dish feel special instead of ordinary.
03 -
  • Toast your panko briefly in a dry skillet over medium heat before mixing with butter and herbs—this extra step creates even more crunch and deepens the flavor.
  • If your mushrooms release a lot of liquid while sautéing, let them cook a bit longer uncovered to evaporate that moisture; this concentrates their earthy flavor instead of diluting your finished sauce.
