Keto Baked Salmon with Asparagus

Ingredient Notes
Salmon
Salmon is the star of this dish and one of the best proteins for a keto diet. It’s rich in omega-3 fatty acids, which support heart health and reduce inflammation. Choose wild-caught salmon if possible for better flavor and nutrition. Skin-on salmon helps retain moisture, but skinless works well too.
Asparagus
Asparagus is a low-carb vegetable that roasts beautifully. It has a mild, earthy flavor and a tender-crisp texture when baked. Trim the woody ends to ensure tenderness.
Olive Oil
Extra-virgin olive oil adds healthy fats and enhances flavor. It helps the salmon and asparagus roast evenly while keeping them moist.
Butter
Butter adds richness and depth, balancing the acidity of lemon and the earthiness of asparagus.
Garlic
Fresh garlic delivers bold flavor and aroma. Minced garlic blends perfectly into the oil and butter mixture.
Lemon Juice & Zest
Lemon brightens the dish and cuts through the richness of salmon. Zest adds concentrated citrus flavor without extra liquid.
Seasonings
Paprika adds subtle warmth and color, oregano gives herbal depth, and salt and pepper enhance all flavors.
Serving Instructions
Serve the salmon warm alongside the roasted asparagus. Garnish with lemon slices and fresh herbs. Pair with keto cauliflower mash, zucchini noodles, or a simple avocado salad for a complete meal.
