Low Sodium Gluten Free Tuna Noodle Casserole

This cozy, oven-baked casserole layers tender gluten free noodles with flaky tuna, sweet peas, and a rich, creamy sauce built from sautéed onion, celery, and garlic. The sauce gets its velvety texture from a broth-and-milk base thickened with cornstarch, then gets finished with a hit of dried thyme and black pepper for warmth. A crunchy topping of gluten free breadcrumbs tossed in melted butter bakes up golden and crisp, giving every scoop that classic contrast of creamy filling and crackly crust. Fresh parsley scattered over the top at the end adds a bright, herby finish. It's the kind of nostalgic, comforting dinner that reheats beautifully, and it's a solid pick for anyone keeping an eye on added salt without giving up flavor or that golden, bubbling casserole top.

Chef's tip
Season to taste - salt substitutes can taste bitter in larger amounts, so start with less.
¼ tsp black pepper

For the topping

1 cup gluten free breadcrumbs
2 tbsp unsalted butter, melted

For serving

2 tbsp fresh parsley, chopped (optional)

Instructions

1
Preheat the oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.
2
Bring a large pot of salted water to a boil. Cook the gluten free pasta according to package directions until just al dente — tender but with a slight resistance at the center. Drain in a colander and set aside. (Gluten free pasta continues to soften in the oven, so pull it 1–2 minutes before fully done.)
