Common Mistakes to Avoid
When making Cajun Shrimp and Crab Mac and Cheese, it’s easy to overlook a few key steps. Here are common mistakes to avoid for the best results.
- Skipping the seasoning: Failing to season your shrimp and cheese mixture properly can lead to bland flavors. Be generous with your spices and taste as you go.
- Overcooking the pasta: Cooking the macaroni too long will make it mushy in the final dish. Aim for al dente, as it will continue cooking in the oven.
- Not letting it rest: Serving right out of the oven can cause a soupy dish. Allowing it to sit lets it set and enhances texture.
- Using low-quality cheese: Cheaper cheeses may not melt well or provide the rich flavor you desire. Opt for fresh, high-quality cheeses for better results.
- Skipping the foil cover: Not covering your mac and cheese midway through baking can lead to a burnt top. Make sure to use foil to protect it from direct heat.
Refrigerator Storage
