Step-by-Step Instructions for Tuna and Broccoli Casserole

Now, let’s get cooking! First, preheat your oven to 375°F (190°C). This ensures it’s hot and ready. Heat the olive oil in a large saucepan. I often use my trusty Dutch oven for this. Cook the chopped onion until it’s soft, about 5 minutes. Then, add the minced garlic. Stir it for just 1 minute until you can smell its lovely fragrance. Don’t let it brown! Next, sprinkle in the flour. Stir constantly for 1 minute. This makes a roux, our sauce base. Gradually whisk in the milk and broth. Keep whisking until the sauce is smooth. It will start to thicken. Stir in the Dijon mustard, salt, and pepper. Cook for 2-3 minutes. The sauce should coat the back of your spoon. Remove it from the heat. Gently fold in the drained tuna. Add the steamed broccoli florets. Stir in the shredded cheddar cheese. Pour this mixture into a 9×13 inch baking dish. In a small bowl, mix the breadcrumbs and melted butter. Sprinkle this over the casserole. Bake for 20-25 minutes. It should be bubbly and golden brown. Let it rest for 5 minutes before serving. This helps it set up nicely.

Crafting the Creamy Sauce for Your Tuna and Broccoli Casserole

Making a great sauce is key to this tuna and broccoli casserole. After cooking the onion and garlic, stir in the flour. This creates a roux, a thickener. Whisk in the milk and broth slowly. This prevents lumps. Keep stirring until it’s smooth and thick. Patience here makes all the difference! The sauce should be rich and velvety. This creamy base truly brings the dish together. It makes every bite delicious.

Assembling and Baking Your Tuna and Broccoli Casserole

Once your creamy sauce is ready, it’s assembly time! Gently fold in the tuna, broccoli, and cheese. Mix it all together. Pour this delicious mixture into your baking dish. For the topping, combine breadcrumbs with melted butter. This creates a golden, crispy crust. Sprinkle it evenly over the casserole. Bake until bubbly. The top should be a beautiful golden brown. This tuna and broccoli casserole will be perfect!

Tips for Success with Your Tuna and Broccoli Casserole
