Common Mistakes to Avoid
When preparing your Dump and Bake Meatball Casserole, avoiding common pitfalls can elevate your dish from good to great.
- Using the wrong pasta: Opting for a type of pasta other than rotini can lead to uneven cooking. Stick to uncooked rotini for best results.
- Skipping the water: Forgetting to add enough water can result in dry pasta. Always ensure you add the specified amount for perfect texture.
- Overbaking the casserole: Leaving it in too long will make the pasta mushy. Check for doneness at 35 minutes and adjust as needed.
- Choosing low-quality sauce: A bland marinara can dull the flavors of your casserole. Invest in a quality marinara sauce that you love.
- Not garnishing: Skipping herbs and cheese at the end minimizes flavor depth. Always finish with Parmesan and fresh herbs for an extra kick.
