Today I’m giving you Low-Carb and Keto Baked Fish Recipes for my weekly round-up of low-carb recipes to try. Of course there are a lot of reasons baked or roasted fish is a great idea. For one thing, fish cooks quickly in the oven. And roasted or baked fish is the ultimate in easy dinner prep! But I am especially sharing this during the holidays because some people celebrate The Feast of the Seven Fishes, and you’ll find some great ideas here for that.

When I started looking through Seafood Recipes for favorites, I found more than 20 different seafood dinners that can be cooked in the oven! And quite a few of these fish recipes are impressive enough that I’ve made them for guests. I’m including a couple of ideas using shrimp, and I also included some quick sheet pan meals with shrimp and salmon.

I’m also a fan of using a toaster oven when you want to bake or roast without heating up the kitchen, and that works well for some of these recipes if you’re not cooking for too many people. Enjoy some low-carb fish dinners everyone, because you know we all should be eating more fish, right?

Use Touch to Tell When Your Fish is Done:

All my fish dinner recipes have a suggested cooking time. But the best way to tell when fish is done is by touch. When the fish feels firm (but not hard) to the touch when you press on it with your fingertip or a fork, you’ll know it’s done. If you use this system regularly you’ll get better at judging the degree of doneness that appeals to you the most.

Side Dishes for Low-Carb and Keto Fish Recipes:

All these recipes are fish dinners, so I want to give you some side dish ideas and I’d love Easy Cheesy Baked Keto Cauliflower, Low-Carb Spicy Cilantro Peanut Slaw, or Lemony Green Beans as a side dish for any of these meals!
