Break the meat into small, uniform pieces and avoid stirring constantly—let it sit 2-3 minutes between stirs to develop deep browning and concentrated flavor that elevates the entire casserole.

Reserve half the shredded taco cheese for the top layer under the cornbread topping; this prevents the bottom cheese from burning while ensuring a melty, golden finish.

Strain canned diced tomatoes through a fine sieve for 5 minutes to remove excess liquid, preventing a watery filling that will soak into the cornbread and make it soggy.

Let your milk, eggs, and oil reach room temperature before mixing into the dry ingredients—this ensures even baking and a tender, moist cornbread topping that rises uniformly.

Allow the casserole to rest for 10-15 minutes after removing from the oven so the layers set slightly, making it easier to cut clean portions while keeping the filling intact.
