How to Serve Keto Baked Mahi Mahi
This baked mahi mahi is delicious on its own, but you can serve it with a side of steamed vegetables or a fresh salad to complete your meal. For extra flavor, a drizzle of lemon juice or a sprinkle of fresh herbs adds brightness. You can also pair it with some cauliflower rice for a low-carb option that allows you to enjoy the dish even more.
How to Store Keto Baked Mahi Mahi
If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Make sure to let the fish cool down completely before sealing. To reheat, place the fillets in the oven at 350°F (175°C) for about 10 minutes or until heated through. Avoid microwaving as it can make the fish chewy.
