Shake up Taco Tuesday with a taco casserole that combines everyone's favorites—seasoned beef, tortilla chips, and all the toppings—in one baking dish. The chips are layered just like noodles in a lasagna and will still keep some of their crunch after baking. As for toppings, the sky's the limit! Go classic with avocado, sour cream, and shredded lettuce, or try adding pickled jalapeños or your favorite salsa. Add this meal to your list of go-to Mexican recipes for any night of the week.

What is in taco seasoning?

Taco seasoning is a bold blend of chili powder, cumin, paprika, oregano, and a few other spices. You can make your own or pick up a packet at the store for this recipe. 

Are poblano peppers spicy? 

Large, dark green poblano peppers are mildly spicy, about halfway between the heat of an Anaheim pepper and a jalapeño. Removing the seeds before cooking helps to tame the heat a bit more. You can also swap the poblano for an Anaheim pepper (long and light green). 

Do you really need to grease the baking dish? 

Coating your baking dish with cooking spray is probably the easiest step to forget, but it's worth doing. Greasing the dish keeps the cheese from gluing to the corners of the casserole and makes scooping and serving easier. As for another big bonus: it makes cleanup easier!
