Common Mistakes to Avoid
When making a Creamy Winter Vegetable Casserole, avoid these common pitfalls to ensure a delicious outcome.
- Skipping the steaming step. Not steaming your vegetables can lead to an uneven texture. Be sure to steam them for 5–7 minutes until just tender for the best results.
- Using cold milk. Adding cold milk to the roux can cause lumps in your cheese sauce. Always warm your milk before whisking it into the roux for a smooth sauce.
- Overbaking the casserole. Leaving it in the oven too long can dry out your dish. Keep an eye on it and remove it once it’s bubbly and golden, usually around 20–25 minutes.
- Ignoring seasoning adjustments. Tasting and adjusting seasoning is crucial. Don’t forget to add salt and pepper according to your taste preferences for a well-balanced flavor.
