Tips for the Cowboy Casserole
- Brown Meat First: Searing the beef before adding it to the slow cooker boosts flavor and texture.
- Layer Tater Tots at the Bottom: This ensures they cook evenly and absorb maximum flavor.
- Cheese Timing: Stir in or top with cheese during the last 10–15 minutes so it melts perfectly without overcooking.
