Common Mistakes to Avoid
When making the Easy Keto Reuben Casserole, it’s easy to overlook a few key steps. Here are some common mistakes to avoid for the best results.
- Incorrectly draining sauerkraut: Not removing excess liquid from the sauerkraut can make the casserole watery. Always drain it thoroughly using a mesh strainer or cheesecloth.
- Skipping the greasing step: If you skip greasing your casserole dish, your casserole may stick and be hard to serve. Use butter or nonstick cooking spray generously.
- Layering inconsistently: Inconsistent layering can lead to uneven cooking. Follow the layering order closely—start with corned beef, then sauerkraut, pickles, sauce, and cheese.
- Overcooking or undercooking: Baking for too long can dry out the casserole, while undercooking will leave it cold in the center. Aim for 10-15 minutes covered and then broil briefly.
- Not allowing leftovers to cool: Placing hot leftovers directly in the fridge can raise temperatures inside, risking food safety. Let it cool before storing.
