Ingredients

6 servings

For the casserole

12 oz gluten free egg noodles or gluten free wide pasta
3 cans (5 oz each) tuna in water, drained
1 cup frozen peas
1 cup cremini mushrooms, thinly sliced

For the cream sauce

3 tbsp unsalted butter
Chef's tip
Use a stick or block-style dairy-free butter - not a soft tub spread - and swap one-for-one.
½ cup yellow onion, finely diced
2 cloves garlic, minced
3 tbsp cornstarch
2 cups chicken broth
1 cup whole milk
Chef's tip
Use the same amount of soy milk as regular milk. It's one of the most reliable milk swaps and works in almost any recipe, including sauces, custards, and baked goods. In cold drinks or uncooked dishes you may notice a mild soy flavor.
½ cup sour cream
1 tsp dijon mustard
1 tsp salt
½ tsp black pepper

For the topping

1 cup gluten free breadcrumbs
2 tbsp unsalted butter, melted
Chef's tip
Use a stick or block-style dairy-free butter - not a soft tub spread - and swap one-for-one.
¼ cup parmesan cheese, finely grated
Chef's tip
Choose a vegan parmesan in the form the recipe uses - grated for sprinkling and sauces, a firm wedge for shaving or melting.

Instructions

1
Preheat the oven to 375°F (190°C). Bring a large pot of salted water to a boil. Cook the gluten free egg noodles according to package directions until just barely al dente — they should still have a firm bite at the center, as they will continue cooking in the oven. Drain in a colander and set aside.
2
In a medium saucepan, melt 3 tbsp butter over medium heat. Add the onion and cook, stirring occasionally, until softened and translucent, about 4–5 minutes. Add the garlic and cook, stirring constantly, until fragrant, about 1 minute. Add the sliced mushrooms and cook, stirring occasionally, until they release their liquid and the pan looks nearly dry, about 4–5 minutes.
