Ingredients

  • 2 teaspoons olive oil
  • 1 pound 85% lean ground turkey (or 2 cups cooked, diced turkey, such as leftover roasted turkey)
  • 1 ½ teaspoon kosher salt, divided
  • 2 tablespoons butter
  • ½ small yellow onion, finely diced
  • 2 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • cups low-sodium chicken broth
  • ½ cup whole milk
  • 3 heaping cups small broccoli florets, roughly chopped (see notes)
  • cups shredded sharp cheddar cheese, divided
  • ¼ teaspoon freshly ground black pepper
  • 2 cups cooked long grain white rice (see notes)

Instructions

  • Preheat & Prep: Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish and set aside.
  • Cook the Turkey: In a large skillet over medium heat, warm the olive oil. Add the ground turkey and ¼ teaspoon of the salt and cook for 5-7 minutes, breaking it up with a spoon, until browned and cooked through. Transfer to a plate and set aside. (If using cooked diced turkey, skip this step.)
  • Sauté the Onion: In the same skillet (no need to wash it first), add the butter, onion, and ¼ teaspoon of salt. Cook over medium heat for 4-5 minutes, stirring, until very soft but not browned. Add the garlic and cook for another 30 seconds until fragrant.
  • Make the Sauce: Turn the heat to low, then sprinkle the flour over the onion, stirring to coat. Cook for about 1 minute, stirring constantly, then slowly whisk in the chicken broth and the milk, stirring to avoid lumps. Simmer for 2-3 minutes until slightly thickened.
  • Once the sauce is slightly thickened, stir in the broccoli and simmer for 2-3 minutes, just until it turns bright green and starts to soften. It will continue to cook a bit more in the oven, so be careful not to overcook in this step. Turn off the heat and add 1 cup of the cheddar cheese, stirring until melted and smooth. Season with 1 teaspoon of the salt and the black pepper.
  • Assemble: Add the cooked turkey and cooked rice to the prepared baking dish. Pour over the sauce and broccoli, mixing to evenly coat. Sprinkle the top evenly with ¾ cup of cheddar cheese.
  • Bake: Cover with foil and bake for 20 minutes, then uncover and bake for 5-10 more minutes until bubbly and golden on top. Let rest for a few minutes before serving.

Notes

  • Rice: For the rice, use leftover cooked or pre-cooked frozen rice. Or cook 1 cup dry long grain white rice according to package directions.
  • Turkey: If using cooked turkey, you will not need the olive oil for this recipe.
  • Broccoli: I like using bagged broccoli florets for convenience, but be sure to give them a rough chop so they cook in the time allotted and disperse more evenly through the casserole. I did test this recipe with frozen broccoli florets, and while I preferred fresh for texture, frozen definitely works and is a great convenience option. If using frozen I recommend defrosting first and then gently squeezing out any extra liquid so it doesn’t water down the final dish.
  • Resting Time: Giving the casserole time to rest will allow the rice to absorb any extra liquid and the cheese sauce time to set a bit, so even though it’s hard to wait, I definitely recommend it!
