Ingredients
- 3 cups mixed mushrooms (cremini,shiitake,and oyster),cleaned and sliced
- 2 tablespoons olive oil
- 1 medium yellow onion,finely chopped
- 3 cloves garlic,minced
- 1 cup baby spinach,roughly chopped
- 1 cup shredded sharp white cheddar cheese
- 1 cup whole milk
- ½ cup heavy cream
- 3 tablespoons all-purpose flour,sifted
- 4 tablespoons unsalted butter
- 1 teaspoon smoked paprika
- 1 teaspoon fresh thyme leaves,chopped
- Salt and freshly ground black pepper to taste
- 1 cup panko breadcrumbs
- 2 tablespoons fresh parsley,chopped (for garnish)
Instructions
- Prepare the mushrooms: Heat the olive oil in a large skillet over medium-high heat.Add the sliced mushrooms and sauté until their moisture evaporates and they become golden brown, about 8-10 minutes. Stir occasionally to prevent sticking and promote even browning. Season with a pinch of salt and pepper.
- Sauté the aromatics: Lower the heat to medium. Add the butter to the pan along with the chopped onion and garlic. Cook until translucent and fragrant, about 5 minutes, stirring frequently so they don’t brown too quickly.
- Create the roux: Sprinkle the flour into the butter and onion mixture. Stir constantly for 2-3 minutes until the flour is fully incorporated and starts to turn a light golden color, which ensures a smooth, thick sauce without a raw flour taste.
- Make the creamy sauce: Gradually whisk in the whole milk and heavy cream, blending fully to avoid lumps. Continue stirring until the sauce thickens, about 5-7 minutes. Season with smoked paprika, fresh thyme, salt, and pepper. Add the chopped baby spinach and cook until wilted.
- Combine all components: Fold the sautéed mushrooms into the creamy sauce. Transfer this mixture into a buttered 9×9-inch casserole dish. Sprinkle the shredded cheddar cheese evenly over the top.
- Add crunchy topping: In a small bowl, toss panko breadcrumbs with a teaspoon of olive oil to help them brown beautifully. Sprinkle evenly over the cheese layer to create a golden, crispy crust.
- Bake to perfection: Preheat your oven to 375°F (190°C). Bake the casserole uncovered for 20-25 minutes, or until the top is golden and bubbly. Allow it to rest for 5 minutes to set before serving for the best texture and flavor harmony.
Tips for Success
- Choosing mushrooms: Opt for a mix of cremini, shiitake, and oyster mushrooms to achieve an ideal balance of earthiness and texture. Avoid overly watery mushrooms like white button mushrooms alone to prevent sogginess.
- Layering flavors: Don’t rush the sautéing of mushrooms and onions. letting them caramelize fully builds base richness that elevates every bite of this savory mushroom casserole.
- Make-ahead tips: You can assemble the casserole up to one day in advance,cover it tightly,and refrigerate. Bring to room temperature before baking.
- Substitutions: Swap cheddar for Gruyère or fontina cheese for a creamier melt and distinct flavor profile.
- For gluten-free version: Replace all-purpose flour with a gluten-free blend and use gluten-free breadcrumbs.
