Ingredients
- 2 cups mixed fresh mushrooms (cremini, shiitake, and oyster), sliced
- 4 cups fresh baby spinach, washed and roughly chopped
- 1 medium onion, finely diced
- 3 cloves garlic, minced
- 2 tablespoons olive oil or avocado oil
- 3 tablespoons gluten-free all-purpose flour
- 2 cups unsweetened almond milk (or any plant-based milk)
- ½ cup dairy-free cream cheese or full-fat coconut cream
- 1 teaspoon dried thyme
- ½ teaspoon smoked paprika
- 1 teaspoon Dijon mustard
- ½ cup shredded gluten-free cheese (optional, for topping)
- Salt and freshly cracked black pepper, to taste
- Fresh parsley, chopped, for garnish
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with oil or non-stick spray.
- Heat olive oil in a large skillet over medium heat. Add diced onions and sauté until soft and translucent, about 5 minutes.

- Incorporate the chopped spinach, stirring until just wilted, about 2 minutes. Season lightly with salt and pepper to enhance natural flavors.
- Sprinkle the gluten-free flour evenly over the vegetables, stirring constantly to create a roux. Cook for 2 minutes to remove raw flour taste but avoid browning.
- Slowly pour in the almond milk, whisking gently to prevent lumps. Add the dairy-free cream cheese (or coconut cream),thyme,smoked paprika,and Dijon mustard. Simmer and stir continuously until the mixture thickens into a rich, creamy sauce, about 5 minutes.
- Transfer the creamy vegetable mixture into your prepared casserole dish. Spread evenly to form a smooth surface.
- Sprinkle gluten-free cheese on top if using, for a bubbly, golden crust.
- Bake uncovered in the oven for 20-25 minutes, or until the casserole is bubbling and the top is lightly browned.
- Remove from oven and let rest for 10 minutes before serving. Garnish with freshly chopped parsley for a pop of color and freshness.
Tips for Success: Crafting the Perfect Creamy Texture and Selecting Ingredients
- Choosing Mushrooms: Opt for an assortment like cremini,shiitake,and oyster mushrooms. Their combined textures and flavors build depth-from earthy to slightly sweet. Avoid overly wet mushrooms; fresh, firm caps are key.
- Selecting Spinach: Baby spinach delivers tenderness and mild flavor. Ensure leaves are fresh and vibrant green with no wilting to keep the casserole lively.
- Gluten-Free Creaminess: Using gluten-free flour with plant-based milk creates a luscious sauce without heaviness.Coconut cream or dairy-free cream cheese adds extra richness while keeping it dairy-free friendly.
- Preventing Sogginess: Avoid overwatering mushrooms by cooking until moisture evaporates. This step is crucial to achieve a thick, pleasing consistency.
- Make-Ahead: Prepare the filling a day prior and store in the fridge. Assemble and bake just before serving to save time and preserve freshness.
