How to Make Squash and Tuna Melt Casserole

1. Prepare the squash: Trim the ends of the squash, slice them in half lengthwise, and sprinkle salt on the cut sides. Let them drain for about 1 hour to remove excess moisture.

2. Sauté the aromatics: In a skillet, heat a generous amount of extra-virgin olive oil over medium heat. Add the sliced scallions, fresh thyme, dried chile flakes, kosher salt, and black pepper. Cook until soft, about 3-4 minutes.

3. Preheat your oven: Set your oven to 450°F so it s nice and hot when it s time to bake the casserole.

4. Roast the squash: Place the squash halves cut-side down on a baking sheet. Roast until slightly shrunk and browned, about 15 minutes this enhances their flavor and texture.

5. Assemble the casserole: Once roasted, flip the squash cut side up in a baking dish. Top with the sautéed scallion mixture, flake the oil-packed tuna over the top, and generously sprinkle the shredded cheddar cheese.

6. Bake to perfection: Place the casserole in the preheated oven and bake until the cheese is melted and bubbly, about 10-15 minutes. Allow it to cool for 5 minutes before serving.
