Ingredients Needed
- Extra lean ground beef (drained or rinsed!) - Is considered better than higher fat options for several reasons. First, it has less saturated fat, which can contribute to heart disease and other health issues. Additionally, it tends to have fewer calories per serving, making it a good option for those watching their weight. The 96% lean ground beef from Aldi is my favorite.
- Onion (chopped) - use minced onion or onion powder if you don't like onions
- Canned jalapeno slices, chopped
- Fresh tomatoes, chopped or 1 (15 oz) can diced canned tomatoes
- Can kernel corn (drained) - refers to corn that has been harvested, cooked, and preserved in a can. It is a popular food item due to its convenience and long shelf life. However, some people prefer fresh or frozen corn for its taste and texture.
- Black beans (rinsed and drained) - are a convenient and versatile ingredient that can be used in a variety of dishes. They are a great source of protein and fiber, and can be added to salads, soups, stews, and even dips.
- Taco seasoning mix - Is a blend of spices used to flavor ground beef or other meats for use in tacos. It typically includes a combination of chili powder, cumin, garlic powder, onion powder, paprika, and sometimes salt and pepper. It can be purchased pre-mixed, or made at home using individual spices. I usually buy the Lower Sodium Taco Seasoning packets such as Mrs Dash.

How to Make Mexican Casserole
Step 1: Brown ground beef and chopped onions in large skillet; brown 10 to 12 minutes or until thoroughly cooked, stirring constantly. Drain all fat from skillet and return beef/onions to skillet.

Pro Tips for Mexican Casserole

Store any leftovers in an airtight container in the refrigerator for up to 4 days. This casserole holds up very well and is perfect for reheating throughout the week.
To reheat, microwave individual portions for 1 to 2 minutes or warm the entire dish in the oven at 350 degrees until heated through.
