Meet your new favorite comfort food: Garden Tuna Casserole. It's a delightful twist on a classic dish, lightened up with fresh veggies and a zesty touch of lemon. Perfect for weeknight dinners or a cozy weekend meal.
Let's dive into what makes this dish shine. First, the elbow macaroni serves as the base, providing that classic comforting texture. You'll sauté a small onion and bell peppers in olive oil, which adds sweetness and a little crunch. A cup of peas brings a pop of color and a touch of sweetness, while tuna introduces a savory, protein-rich element. Cherry tomatoes add freshness and a juicy burst, and sharp cheddar cheese gives the casserole its irresistible cheesiness. The combination of sour cream and mayonnaise creates a creamy, tangy sauce, with a hint of brightness from lemon zest. Finally, a breadcrumb and parsley topping gives you a satisfying crunch.
This casserole pairs wonderfully with a simple green salad dressed in a lemon vinaigrette. The acidity cuts through the richness of the dish. A side of crusty bread works well to mop up any extra sauce.
First, preheat your oven to 350°F (175°C). While that's warming up, cook the elbow macaroni according to the package instructions. Don't forget to season the water with a pinch of salt—it makes a difference. Once cooked, drain the pasta and set it aside.
Heat up your olive oil in a large skillet over medium heat. Add the diced onion and bell peppers. Sauté them until they're soft and fragrant, which should take about 5 minutes. Stir in the peas and let them cook for another 2 minutes. This quick cook time keeps them vibrant and tender.
In a large mixing bowl, combine the cooked macaroni, your sautéed veggies, tuna, cherry tomatoes, cheddar cheese, sour cream, mayonnaise, lemon zest, salt, and pepper. Mix everything thoroughly so each bite is loaded with flavor.
Transfer this delicious mixture to a greased 9x13 inch baking dish. In a small bowl, combine breadcrumbs with chopped parsley, then sprinkle evenly over the casserole. This step is key for that golden, crunchy topping.
Pop the dish into your preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbly. Once done, let it cool for a few minutes before serving. This short rest lets the flavors meld together beautifully.
