How to make ground beef casserole with French fried onions
Honestly what I love most about casseroles is that it’s hard to screw them up. Add something, omit something… casseroles don’t care. Somehow everything just comes together and it works no matter how you twist things.
But, here’s how I make this crunchy beef casserole bake.
Step 1: Prepare elbow mac according to package directions; drain. While it’s boiling, brown the ground beef, crumbling as it cooks. Drain off extra grease.
Step 2: In large bowl, combine all ingredients, using just half the onions. Set the other half aside. Pour the mixture into a 2-quart casserole dish or 9 x 13-inch baking dish.
Step 3: Cover and bake for 30 minutes. Sprinkle remaining half of onions on top and bake, uncovered for another 5 minutes.
Variations and substitutions
Substitute ground turkey for the ground beef.
Add a cup of frozen corn.
Add a can of canned green beans.
For a little kick, add a small amount of red pepper flakes.
Try making it with chow mein noodles.
Enjoy!
