Difficulty Level

Ingredients
- 3 cups gluten-free pasta (such as brown rice penne or quinoa rotini), cooked al dente
- 2 cans (5 oz each) tuna in water, drained and flaked
- 2 cups fresh mushrooms, sliced
- 1 medium onion, finely diced
- 3 cloves garlic, minced
- 2 cups unsweetened almond milk (or your preferred gluten-free milk alternative)
- 3 tablespoons gluten-free all-purpose flour
- 4 tablespoons unsalted butter
- 1 cup gluten-free bread crumbs (for topping)
- 1 cup sharp white cheddar cheese, shredded
- 1/4 cup frozen peas, thawed
- 1 teaspoon Dijon mustard
- 1 teaspoon dried thyme
- Salt and freshly ground black pepper, to taste
- Fresh parsley, chopped for garnish
Instructions
- cook the gluten-free pasta according to package instructions until al dente. Drain and rinse under cold water to stop cooking,then set aside.
- Prepare the creamy base: In a large skillet over medium heat, melt the butter. Add diced onions and sauté until translucent, about 4 minutes.Stir in minced garlic and cook another 1 minute, until fragrant.
- Create the roux: Sprinkle the gluten-free flour evenly over the onion mixture. Stir continuously for 2-3 minutes to cook out the raw flour flavor and achieve a light golden hue. This ensures a smooth, velvety sauce without lumps.
- Slowly whisk in almond milk, a little at a time, making sure the mixture stays smooth. Add Dijon mustard and dried thyme. Continue stirring until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Adjust seasoning with salt and pepper.
- Add mushrooms and peas, and cook for 3-4 minutes until mushrooms release moisture but remain firm. Avoid overcooking to keep texture contrast in the casserole.
- Fold in the drained tuna and shredded cheddar cheese,combining them gently into the sauce. Lastly, incorporate the cooked gluten-free pasta, making sure every piece is enveloped in the creamy sauce.
- Transfer the mixture to a greased 9×13-inch baking dish. Evenly sprinkle the gluten-free bread crumbs over the top to create a golden, crunchy crust.
- Bake uncovered at 375°F (190°C) for 20-25 minutes, until the casserole is bubbling and the topping turns a gorgeous golden brown. Let rest for 5 minutes before serving to help set the sauce.
Tips for Success
- Ingredient swaps: Use coconut milk for a creamier, dairy-free sauce or swap cheddar for mozzarella for a milder flavor.
- Texture matters: Don’t overcook the mushrooms or peas to maintain a balance of bite and tenderness.
- Make ahead: Assemble the casserole the day before, cover tightly with foil, and refrigerate. bake fresh before serving.
- gluten-free breadcrumbs: Use crushed gluten-free crackers or rice cereal as a crunchy alternative to customary breadcrumbs.
- Enhance flavor: A squeeze of fresh lemon over the tuna before folding in adds a bright, zesty note that elevates the entire dish.
Creative Serving Suggestions
Present your casserole with a sprinkle of fresh parsley or chives for color and added freshness. Pair it alongside a crisp, lightly dressed salad featuring seasonal greens or a refreshing cucumber and dill salad to contrast the creamy richness. For an inviting family-style meal, place individual ramekins under the broiler briefly to achieve bubbling, golden edges that invite instant indulgence.For a pop of texture, serve with crunchy roasted almonds or pine nuts on the side. To round out the platter, a simple bowl of pickled vegetables adds both tang and vibrant visual appeal.
