Ingredients You’ll Need

- 8 ounces wide egg noodles
- 2 cans (5 ounces each) tuna in water, drained
- 1 cup frozen peas, thawed
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1 cup chicken or vegetable broth
- 1 cup shredded cheddar cheese
- 1/2 cup breadcrumbs
- 1/4 cup grated Parmesan cheese
- 1 teaspoon dried thyme
- Salt and black pepper to taste
Step-by-Step Instructions
Step 1: Preheat your oven to 375°F (190°C). Cook the egg noodles according to package directions until al dente. Drain and set aside.
Step 2: In a large skillet, melt butter over medium heat. Add chopped onion and cook until softened, about 5 minutes. Add minced garlic and cook for another minute until fragrant.
Step 3: Sprinkle flour over the onion mixture and whisk continuously for 1 minute to create a roux. Gradually pour in milk and broth while whisking constantly to prevent lumps.
Step 4: Bring the sauce to a simmer and cook until thickened, about 3-4 minutes. Stir in dried thyme, salt, and pepper. Remove from heat and stir in 3/4 cup of cheddar cheese until melted.
Step 5: In a large mixing bowl, combine the cooked noodles, drained tuna, peas, and creamy sauce. Gently fold everything together until well combined.
Step 6: Transfer the mixture to a greased 9×13 inch baking dish. In a small bowl, mix breadcrumbs, remaining 1/4 cup cheddar cheese, and Parmesan cheese. Sprinkle evenly over the casserole.
Step 7: Bake for 25-30 minutes until bubbly and the topping is golden brown. Let stand for 5 minutes before serving.
Expert Tips for Perfect Results
Choose Quality Tuna: Opt for tuna packed in water rather than oil for a lighter casserole. Albacore tuna works particularly well for its firm texture and mild flavor.
Don’t Overcook Noodles: Cook the egg noodles just until al dente since they’ll continue cooking in the oven. This prevents them from becoming mushy.
Make Ahead Friendly: You can assemble the casserole up to a day in advance. Cover and refrigerate, then add 5-10 minutes to the baking time when ready to cook.
Customize Your Topping: For extra crunch, mix crushed potato chips or fried onions with the breadcrumb topping. This adds wonderful texture contrast to the creamy base.
This comfort food classic pairs beautifully with simple sides. Consider serving it with a crisp green salad or steamed vegetables for a complete meal that satisfies the whole family.
Frequently Asked Questions
Can I use different pasta? Absolutely! While egg noodles are traditional, you can substitute with fusilli, penne, or shells. Just adjust cooking time according to package directions.
How long does leftover casserole keep? Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F for best results.
Can I make this recipe gluten-free? Yes! Use gluten-free noodles and substitute the flour with cornstarch or gluten-free flour blend. Check that your breadcrumbs are also gluten-free.
What other vegetables can I add? Diced carrots, mushrooms, or corn make excellent additions. Just sauté them with the onions to ensure they’re tender when baked.
