This baked lemon dijon salmon is a simple recipe you’ll love. It’s gluten-free, dairy-free, keto, paleo, low carb and ready in less than 15 minutes. It’s great on the barbecue or in your oven. I love to make it for meal prep so I can enjoy a couple of servings of salmon during the week (and only cook it once).
It’s rare to find a sugar-free marinade recipe. I guess most of us have a sweet tooth (my hand is up over here)! But with some tanginess from lemons, freshness from the zest and spice from the grainy mustard, you won’t be missing the maple or honey found in most fish marinade recipes.
Pair your baked lemon dijon salmon with some salad, green beans or other favorite vegetables. It’s also yummy with cauliflower rice or brown rice noodles.
Health Benefits of Salmon
Salmon and other oily fish are excellent sources of omega-3 fatty acids and vitamin D. (Find out how much vitamin D you need and whether you need a supplement).
Salmon and Vitamin D
- A 3 ounce serving (about the size of the palm of your hand or a deck of cards) of salmon serves up about 450 IU of vitamin D. That’s almost our daily goal (make sure you get some sunshine on your hands and face too).
- Getting enough vitamin D (based on blood tests) may reduce the risk of colorectal cancer.
Salmon and Omega-3 Fatty Acids
- Omega-3s are essential fatty acids, meaning your body can’t make enough of them and you need to get them from your diet.
- Omega-3s have many heart health benefits. They may help lower your risk of stroke by preventing blood clotting. Omega-3s can lower triglyceride levels and raise HDL (healthy cholesterol levels).
- Aim for 2-3 servings of oily fish such as salmon every week to get enough EPA and DHA, omega-3s that are important for brain health and for preventing depression.
