Ingredients
Scale
- 1 tablespoon olive oil
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1/2 cup all-purpose flour
- 2 cups milk (dairy or non-dairy)
- 1/2 cup chicken or vegetable broth
- 1 teaspoon Dijon mustard
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 (5 ounce) cans tuna in water, drained
- 4 cups broccoli florets, steamed until tender-crisp
- 1 cup shredded cheddar cheese
- 1/2 cup breadcrumbs
- 2 tablespoons melted butter
Instructions
- Preheat your oven to 375°F (190°C).
- Heat olive oil in a large saucepan or Dutch oven over medium heat. Add chopped onion and cook until softened, about 5 minutes. Add minced garlic and cook for 1 minute more until fragrant.
- Stir in the flour and cook for 1 minute, stirring constantly, to create a roux.
- Gradually whisk in the milk and broth until the sauce is smooth and thickened.
- Stir in the Dijon mustard, salt, and pepper. Cook for 2-3 minutes, stirring, until the sauce coats the back of a spoon.
- Remove the sauce from heat. Gently fold in the drained tuna, steamed broccoli florets, and shredded cheddar cheese.
- Pour the mixture into a 9×13 inch baking dish.
- In a small bowl, combine the breadcrumbs and melted butter. Sprinkle the breadcrumb mixture evenly over the casserole.
- Bake for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
- Let the casserole rest for 5 minutes before serving.
Notes
- For a richer flavor, use a combination of cheddar and Monterey Jack cheese.
- You can add a pinch of nutmeg to the sauce for extra depth.
- If you prefer a milder onion flavor, use shallots instead of onion.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
