How to Make Tuna Casserole
- Preheat the oven to 350°F (175°C): This prepares the environment for a beautiful bake.
- Make the Sauce: In a saucepan, melt 2 tablespoons of butter over medium heat. Whisk in 2 tablespoons of flour slowly and cook for 1-2 minutes, stirring continuously to avoid burning. Gradually whisk in 1 cup of milk and 1/4 cup of heavy cream until the mixture thickens and begins to bubble. Season it with 1/2 teaspoon salt, 1/4 teaspoon pepper, and 1/8 teaspoon nutmeg, then transfer to a large mixing bowl.
- Prepare the Noodles: In a large pot, boil 2 cups of dried egg noodles in salted water until they are al dente. Drain and set aside.
- Sauté the Vegetables: In a skillet, heat 1 tablespoon of butter over medium heat. Add in the diced onion, chopped cremini mushrooms, and finely diced celery; sauté them while stirring occasionally for about 8-10 minutes until tender. Stir in 1/2 cup of peas, 1/8 teaspoon salt, 1/8 teaspoon pepper, and 1/4 teaspoon lemon zest, and finally fold in the drained tuna before removing from heat.
- Combine and Bake: In your mixing bowl containing the sauce, add in the sautéed filling and the drained noodles. Stir everything well to combine, and then divide the mixture between two 10-ounce ramekins or an appropriately sized baking dish. Top with 1/2 cup of breadcrumbs, drizzle with 1 tablespoon of melted butter, and bake for 20 minutes until bubbling.
Storing & Reheating
Store leftovers in an airtight container at room temperature for no longer than 2 hours, or keep them in the refrigerator for up to 4 days. For longer storage, tuna casserole can be frozen in an airtight container for up to 3 months. When reheating, simply warm in the oven at 350°F (175°C) for about 20 minutes, or until heated through. Note that while the flavors stay delectable, the creaminess may be slightly altered after freezing. To refresh the texture, consider adding a splash of milk when reheating.
Chef’s Helpful Tips
- Be sure to watch the sauce closely when thickening to prevent any lumps from forming.
- For the best flavor, always use fresh spices, and feel free to experiment with herbs like thyme or parsley!
- If making ahead, assemble your casserole without baking and store it in the fridge, then bake just before serving.
- If you notice your casserole is too dry, try adding a little more cream or milk to the mixture before baking for that extra moisture.
- Clean up is a breeze when you use only a few pots, so maximize the flavor without overwhelming your comfort.
Tuna casserole brings comfort and satisfaction in every bite, melding together creamy textures with bursts of flavor. Don’t hesitate to experiment with your favorite ingredients or toppings; you might discover a new twist on this classic dish!
