Step‑by‑Step Instructions for Delicious Tuna Casserole Freezer Meal
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure that your Delicious Tuna Casserole Freezer Meal bakes evenly and performs beautifully once it’s ready to go in. A properly heated oven is key to achieving that golden, bubbly top we all love!
Step 2: Cook the Pasta
Bring a large pot of salted water to a rolling boil. Add in your elbow macaroni and cook for 7-8 minutes, until al dente. It’s important not to overcook the pasta, as it will continue to soften in the oven. Once done, drain the pasta and give it a quick rinse with cool water to stop the cooking process.
Step 3: Make the Roux
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Once it’s fully melted, whisk in an equal amount of flour, stirring constantly for 3-4 minutes until the mixture turns a light golden color. This roux is crucial for creating a rich and creamy base for your tuna casserole.
Step 4: Create the Sauce
Gradually whisk in 2 cups of chicken broth, ensuring there are no lumps. Keep cooking for 5-7 minutes, allowing the sauce to thicken. You’ll know it’s ready when it coats the back of a spoon. This creamy sauce is what makes your Delicious Tuna Casserole a crowd favorite!
Step 5: Add the Mayonnaise
Remove the sauce from heat and let it cool slightly for a few minutes. Once cooled, gently mix in 1 cup of mayonnaise. This step is essential—increasing creaminess while preventing separation. Make sure the mixture is smooth and well-combined before moving on.
Step 6: Combine Ingredients
In a large mixing bowl, combine the cooked macaroni, the creamy sauce, 2 cans of drained tuna, 2 cups of shredded cheddar cheese, and your chosen seasonings. Stir well until every ingredient is evenly coated in that luscious sauce. This is the heart of your Delicious Tuna Casserole Freezer Meal!
Step 7: Assemble the Casserole
Transfer the mixture into a greased 9×13 inch baking pan. Spread it out evenly, and sprinkle the remaining cheddar cheese on top for that irresistible crispy finish. This assembly phase makes your Delicious Tuna Casserole ready to hit the oven and bring comfort to your dinner table!
Step 8: Bake to Perfection
Bake your casserole uncovered for 30-45 minutes in your preheated oven. You’ll know it’s ready when the cheese is melted, bubbling, and forms a golden crust. The delicious aroma wafting through your kitchen will be hard to resist while you wait for the meal to finish!
Step 9: Freezing for Later
If you plan to freeze the casserole, cover it tightly with plastic wrap and aluminum foil before placing it in the freezer. This helps prevent freezer burn. For the ultimate Delicious Tuna Casserole experience, bake directly from frozen, adding an extra 15-20 minutes to the cooking time when you’re ready to enjoy!
