Cook techniques
Sautéing
Sautéing is a cooking method that involves cooking food quickly in a small amount of oil over relatively high heat. This technique is used here to soften the onions and cook the garlic until fragrant, enhancing the flavor profile of the dish.
Browning
Browning ground turkey helps to develop a rich flavor and adds a nice texture. This technique involves cooking the meat until it is no longer pink and begins to form a brown crust.
Simmering
Simmering involves cooking food gently in a liquid at a low temperature. In this recipe, it allows the ingredients to meld together and enhances the overall flavor of the sauce.
Mixing
Mixing ensures that all ingredients are evenly distributed. This technique is crucial when adding the rice and spinach to incorporate them thoroughly within the casserole.
Baking
Baking is a method of cooking food using dry heat in an oven. In this recipe, baking ensures that the casserole is heated through, the cheese melts, and the flavors meld perfectly.
Covering
Covering the baking dish with aluminum foil prevents the cheese from over-browning too quickly and helps retain moisture in the casserole during the first part of baking.
Resting
Letting the casserole sit for a few minutes after baking allows the dish to set up, making it easier to serve and enhancing the flavors.
