Spread this 1 mixture over salmon in a baking dish for a low carb bake that’s surprisingly luxurious

This baked salmon with a creamy, low-carb topping is one of those weeknight heroes I lean on when I want something that feels a little fancy but doesn’t require me to hover over the stove. Think of it as a lighter, easier cousin to classic baked fish with a rich sauce—only here, the creaminess comes from a quick mix of Greek yogurt, mayo, and Parmesan instead of a flour-thickened sauce.

It’s the kind of dish that works when you’re juggling emails, laundry, and figuring out tomorrow’s schedule, but still want dinner to feel intentional and nourishing. If you’re watching carbs or just trying to cut back on heavy pastas and breads, this is a great way to get that cozy, comfort-food vibe without the carb hangover.

This salmon pairs really well with simple, low-carb sides that you can throw together while it bakes. I love serving it with roasted asparagus or green beans tossed in olive oil, salt, and pepper—just pop them in the oven on a separate sheet pan. A crisp side salad with mixed greens, cucumber, and a tangy vinaigrette balances the richness of the creamy topping.

If you want something a bit heartier but still low carb, try cauliflower mash or roasted cauliflower florets. For meal prep, you can portion the salmon with a side of steamed broccoli and a scoop of cauliflower rice so lunches are ready to grab from the fridge.

Low Carb Baked Salmon with Creamy Parmesan Topping

Servings: 4 servings

Ingredients

1 1/2 to 2 pounds salmon fillet (about 4 portions), skin-on or skinless
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 teaspoon garlic powder
1 tablespoon olive oil (for brushing the pan or foil)
1/3 cup plain Greek yogurt (full-fat or 2%)
3 tablespoons mayonnaise
1/3 cup grated Parmesan cheese
1 teaspoon Dijon mustard
1 teaspoon lemon zest (optional but recommended)
1 tablespoon fresh lemon juice
1 tablespoon chopped fresh dill or parsley (or 1 teaspoon dried)
Pinch of paprika or smoked paprika (optional, for color)
Lemon wedges, for serving

Directions

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil, then lightly brush or spray it with olive oil to prevent sticking.

Place the salmon fillet on the prepared baking sheet, skin-side down if using skin-on. Pat the salmon dry with paper towels so the topping adheres better.

Season the salmon evenly with salt, black pepper, and garlic powder.

In a small bowl, stir together the Greek yogurt, mayonnaise, Parmesan cheese, Dijon mustard, lemon zest, lemon juice, dill or parsley, and paprika (if using) until smooth and well combined.

Spoon the creamy mixture over the top of the salmon, spreading it into an even layer that covers the fish from end to end. It’s okay if a little drips down the sides.

Bake the salmon in the preheated oven for 12–15 minutes, depending on the thickness of your fillet, until the fish flakes easily with a fork and the topping is set and lightly golden around the edges.

If you’d like a deeper golden top, switch the oven to broil for 1–2 minutes at the end, watching closely so it doesn’t burn.

Remove the salmon from the oven and let it rest for 3–5 minutes. Slice into portions and serve with lemon wedges for squeezing over the top.


Variations & Tips

If your evenings are especially hectic, you can mix the creamy topping a day in advance and stash it in the fridge; then all you have to do is spread and bake when you get home. For a slightly lighter version, use all Greek yogurt and skip the mayo, adding an extra pinch of salt and a drizzle of olive oil for richness. If you’re dairy-free, try using a dairy-free mayo plus a spoonful of unsweetened coconut yogurt and skip the Parmesan, or swap it for a dairy-free Parmesan-style cheese.

You can also play with herbs: swap dill for basil, chives, or Italian seasoning depending on what you have on hand. For a little kick, add a pinch of red pepper flakes or a dash of hot sauce to the creamy mixture. If you’re cooking for one or two, halve the recipe and bake a smaller piece of salmon, or cook the full amount and portion leftovers into containers—this reheats nicely in the oven or microwave and makes an easy, low-carb lunch for the next couple of days.
