Common Mistakes to Avoid
When making Keto Garlic Shrimp Au Gratin, it’s essential to avoid common pitfalls that can affect the dish’s flavor and texture.
- Bold seasoning: Forgetting to season the shrimp properly can lead to bland results. Always season with salt and pepper before cooking for enhanced flavor.
- Bold overcooking shrimp: Cooking shrimp too long makes them rubbery. Sear them just until pink; they will continue cooking in the oven.
- Bold wrong cheese: Using non-keto cheeses can ruin your dish. Stick to high-fat, low-carb options like parmesan and Monterey jack for the right texture and flavor.
- Bold skipping aromatics: Neglecting onions or garlic means missing out on depth of flavor. Sauté them until fragrant for a delicious base.
- Bold incorrect baking time: Baking for too long can dry out the dish. Keep an eye on it, aiming for that golden top while ensuring the sauce remains creamy.
