Common Mistakes to Avoid
When making Keto Garlic Shrimp Au Gratin, there are a few common pitfalls you should watch out for. Here are the key mistakes to avoid for a perfect dish.
- Overcooking shrimp: It’s important to sear shrimp just until they turn pink. Overcooked shrimp can become rubbery. Aim for about 1–2 minutes per side.
- Skipping the seasoning: Don’t forget to season your shrimp with salt and pepper before cooking. Proper seasoning enhances the flavors of the dish.
- Using cold cream: Cold heavy cream can cause the sauce to separate. Always let it come to room temperature before adding it to the skillet.
- Neglecting the baking time: Keep an eye on your dish while it bakes. Baking too long can dry out the shrimp and sauce. Look for a golden top and bubbling sauce.
- Not letting it rest: Allowing the dish to sit for a few minutes after baking helps thicken the sauce and improves texture.
