Tips

• Browning the beef first gives the casserole a richer flavor.
• Use lean ground beef to reduce excess grease.
• Sharp cheddar provides the best cheesy flavor.
• Add cooked pasta or rice if you want an even heartier casserole.
• Stir in a little sour cream before serving for extra creaminess.
• Top with sliced green onions, crushed tortilla chips, or jalapeños for extra texture and flavor.
• Leftovers taste even better the next day.

Notes

• Store leftovers in an airtight container in the refrigerator for up to 4 days.
• Freeze individual portions for up to 3 months.
• Reheat in the microwave or on the stovetop with a splash of milk or broth if needed.
• You can substitute cream of chicken or cheddar soup for cream of mushroom soup.
