You're going to love this classic Tuna Noodle Casserole! This creamy and comforting dish is quick and easy to make and will taste just as good as you remember from childhood.
0 Preheat the oven to 350°F.
1 Bring a large pot of water to boil and cook the noodles according to package instructions, then drain and set aside.
2 While the noodles are cooking, add the butter to a large, heavy-bottomed pan or cast-iron over. Once butter is melted, add the onion, garlic, and mushrooms. Saute for 4-5 minutes, until the onion and mushrooms have started to brown.
3 Add the flour to the onion and mushroom mixture and toss to coat, then slowly whisk in the milk and broth. Continue whisking until there are no remaining clumps.
4 Next, stir in the salt, pepper, peas, and tuna and let the mixture come to a bubble. Once bubbling, add the cooked and drained pasta and toss to coat.
5 Transfer the mixture to a 3 quart casserole dish, top with cheese, if desired, and bake at 350°F for 20 minutes, until hot and bubbling. Remove from the oven, garnish with parsley, and serve!
