Instructions
- Prep for Success:
- Preheat your oven to 190°C (375°F) and give your 9x13-inch (23x33 cm) baking dish a light grease. This ensures nothing sticks and your casserole browns beautifully.
- Cook the Wild Rice:
- In a medium saucepan combine the rinsed wild rice blend vegetable broth and salt. Bring it to a gentle boil then reduce the heat cover and let it simmer for about 40 to 45 minutes until the rice is tender and has absorbed the liquid.
- Sauté the Veggies:
- While the rice simmers heat olive oil in a large skillet over medium heat. Toss in the chopped onion and let it soften for about 3 minutes then add the minced garlic mushrooms celery and carrot. Keep cooking for 8 to 10 minutes until the vegetables are tender and the mushrooms have a nice golden brown. Stir in the thyme and black pepper for the last minute to bloom their flavors.
- Build the Cream Sauce:
- In a separate saucepan melt the unsalted butter over medium heat. Whisk in the flour and cook for just 1 minute to remove any raw flour taste. Gradually whisk in the whole milk then continue to simmer and stir constantly for about 4 to 5 minutes until the sauce thickens to a lovely consistency.
- Finish the Sauce:
- Take the saucepan off the heat and stir in the sour cream Dijon mustard and grated Parmesan cheese until everything is wonderfully smooth and creamy. Taste it and adjust seasoning if needed.
- Assemble the Casserole:
- In a large mixing bowl gently combine the cooked wild rice the sautéed vegetables and the rich cream sauce. Mix everything thoroughly but gently then spread this glorious mixture evenly into your prepared baking dish.
- Top it Off:
- In a small bowl mix the panko breadcrumbs with the melted butter. Sprinkle this buttery breadcrumb mixture generously over the top of the casserole.
- Bake to Golden Perfection:
- Pop the dish into your preheated oven and bake for 25 to 30 minutes or until the casserole is bubbling around the edges and the panko topping is beautifully golden brown. Let it cool for just 5 minutes before serving to allow the flavors to meld and garnish with fresh parsley if you like.
Save My youngest who typically eyes anything with visible mushrooms with great suspicion actually asked for a second helping of this casserole. He even helped himself to the leftovers for lunch the next day!

It became more than just dinner it was a small victory in the ongoing saga of feeding a picky eater.
Mushroom Magic and Sauté Secrets
The key to truly flavorful mushrooms lies in not overcrowding the pan. If you're working with a lot sauté them in batches to ensure they brown nicely instead of steaming and becoming watery. A hot skillet and a little patience go a long way in developing that rich umami depth.
Mastering the Cream Sauce
A smooth lump-free cream sauce is easier than you think if you follow a few simple steps. Gradually whisking in the cold milk into your hot roux helps prevent lumps allowing the flour to disperse evenly. Keep whisking consistently until it thickens to that perfect luscious consistency.
Customizing Your Casserole
This recipe is wonderfully adaptable to whatever you have on hand or what your family prefers. Feel free to swap out the cremini for shiitake or oyster mushrooms for a different earthy note. If you want to add some greens spinach or kale can be wilted into the vegetable mixture during the last few minutes of sautéing.
- For a heartier meal consider stirring in some shredded cooked chicken or turkey.
- To make it gluten-free simply use a gluten-free all-purpose flour blend for the roux and gluten-free panko breadcrumbs for the topping.
- A splash of dry white wine or sherry added to the vegetables before the cream sauce can also deepen the flavor profile.
Save This Creamy Mushroom and Wild Rice Casserole isn't just a recipe it's an invitation to create warmth and comfort in your own kitchen. I hope it brings as much joy to your table as it has to mine.
