Prep Time: 15 minutes
Cook Time: 25 minutes
Servings: 4
Ingredients:
- 2 cans (12 oz. each) of tuna in water, drained
- 8 oz. of wide egg noodles
- 2 tablespoons of olive oil
- 1 small onion, finely chopped
- 1 cup of frozen peas
- 1 cup of sliced mushrooms
- 1 cup of shredded cheddar cheese
- 1 cup of sour cream
- 1 cup of mayonnaise
- 1/2 cup of grated Parmesan cheese
- 1/2 teaspoon of garlic powder
- 1/2 teaspoon of dried thyme
- Salt and pepper to taste.
- 1 cup of crushed potato chips
Instructions:
- Preheat your oven to 350°F (175°C). Coat a 9×13-inch baking dish with cooking spray and set it aside.
- Prepare the egg noodles following the instructions on the package until they reach al dente perfection. Afterward, drain them and keep them aside.
- In a generously sized skillet, warm the olive oil over medium heat. Introduce the finely chopped onion and cook it until it takes on a translucent appearance, which should take roughly 3-4 minutes.
- Next, incorporate the frozen peas and sliced mushrooms into the skillet. Continue cooking for an additional 3-4 minutes until the mushrooms turn tender.
- In a separate mixing bowl, blend the drained tuna, cheddar cheese, sour cream, mayonnaise, grated Parmesan cheese, garlic powder, dried thyme, salt, and pepper. Ensure that all the ingredients are well combined.
- Add the cooked egg noodles into the tuna mixture, gently folding them in. Then, fold in the sautéed vegetables.
- Transfer this mix of tuna and noodles to the greased baking dish. Spread the crushed potato chips evenly over the top layer.
- Place the baking dish into the preheated oven and let it bake for 20-25 minutes. You’ll know it’s ready when the casserole becomes hot and bubbly, and the potato chip topping takes on a golden-brown hue.
- Once the timer rings, take the casserole out of the oven and allow it to cool for a few minutes before serving.
