Smoked Salmon and Egg White Frittata Low Carb with Spinach and Dill

Smoked Salmon and Egg White Frittata Low Carb with Spinach and Dill is the kind of recipe that earns a permanent spot in your weekly rotation. At only 142 calories per serving and a striking 28 grams of protein, it delivers serious nutritional weight without the heaviness that comes with whole-egg frittatas or cream-loaded bakes. The carb count sits at just 4 grams, which makes it a genuine fit for ketogenic eating rather than a recipe that merely gestures toward low-carb principles. What separates this frittata from other high-protein breakfast options is the combination of wild smoked salmon and egg whites working together. You get layered, savoury depth that you would never achieve from plain egg whites alone. The spinach and dill bring freshness and colour, so the finished dish looks as good as it tastes. For anyone tracking macros carefully or trying to stay full through a long morning without heavy fat intake, this recipe does the work efficiently and without fuss.

Each ingredient in this frittata has a clear reason for being here. The eight egg whites form the protein backbone of the dish, contributing the bulk of those 28 grams while keeping fat and cholesterol low compared to whole eggs. Wild smoked salmon adds a concentrated hit of omega-3 fatty acids, B12, and additional protein, and using wild-caught fish rather than farmed increases the omega-3 content noticeably. Baby spinach brings iron, folate, and vitamin K, and it wilts down so thoroughly during cooking that even people who are cautious about greens rarely notice its presence. Reduced-fat feta cheese provides calcium and a salty, tangy note that ties the flavours together without loading the dish with saturated fat. Capers are small but genuinely useful here, offering a briny punch alongside trace antioxidants. Fresh dill adds more than flavour: it contains small amounts of manganese and vitamin C. The garlic contributes allicin compounds with known anti-inflammatory properties, and the extra virgin olive oil ensures the frittata releases cleanly from the pan while adding heart-healthy monounsaturated fats.

When this frittata comes out of the oven, the surface has a gentle golden colour with visible flecks of green dill and dark spinach against the pale egg white base. The smoked salmon sits in soft, slightly caramelised ribbons across the top and through the body of the frittata. The texture is set but not rubbery, which is the key challenge with egg white cooking. Using a small amount of almond milk loosens the mixture and prevents that squeaky, overcooked quality that egg white dishes can fall into. The process starts on the hob, where you sauté the garlic, spring onions, and spinach briefly in olive oil before pouring the seasoned egg white mixture over the top. Finishing it under a medium grill or in a moderate oven allows the top to set without the bottom burning. The result smells of smoked fish, fresh herbs, and something faintly toasty from the paprika. The taste is savoury and bright, with the dill cutting through the richness of the salmon cleanly.

This recipe supports several specific health goals at once. The high protein content with low overall calories makes it well suited to body recomposition, where the goal is preserving or building muscle while managing calorie intake. The 4 gram carb count means it fits comfortably within standard ketogenic targets and also suits people following a low glycaemic diet for blood sugar management. The absence of gluten makes it a reliable choice for coeliac diners or those with non-coeliac gluten sensitivity, with no substitutions required. Athletes eating in the morning before training benefit from the fast-absorbing protein from egg whites, which is available to muscle tissue more quickly than protein from whole eggs or meat. People managing cardiovascular health get the omega-3s from the salmon alongside the monounsaturated fats from olive oil, a combination consistently linked to improved lipid profiles. The low sugar content, just 1 gram, also means this breakfast avoids the mid-morning energy crash that higher-carb options tend to cause.

This frittata is genuinely meal prep friendly, which is part of what makes it practical rather than just nutritionally impressive. You can make the full frittata on a Sunday, slice it into portions, and refrigerate it in an airtight container for up to four days. The texture holds well in the fridge and does not become watery as some egg dishes do. To reheat, a dry pan over low heat for two to three minutes works better than a microwave, which can make egg whites tough. For freezing, individual slices wrapped tightly in film and sealed in a bag will keep for up to six weeks. Variations worth trying include swapping the smoked salmon for hot-smoked trout, which gives a flakier texture and slightly earthier flavour. You could also use rocket in place of spinach for a peppery edge, or add thinly sliced courgette to increase the vegetable content without significantly changing the carb count. Replacing feta with a small amount of goat cheese changes the creaminess and works beautifully with dill. The full recipe with quantities, timings, and step-by-step instructions is in the recipe card below.

Ingredients

Serves:6
  • 8 large egg whites (from fresh eggs or a carton of liquid egg whites)
  • 2 tablespoons unsweetened almond milk (or any unsweetened plant-based milk)
  • 120 g wild smoked salmon (torn or roughly chopped into bite-sized pieces)
  • 80 g baby spinach (fresh, roughly chopped)
  • 4 medium spring onions (thinly sliced, white and green parts)
  • 60 g reduced-fat feta cheese (crumbled)
  • 1 tablespoon capers (drained and roughly chopped)
  • 2 tablespoons fresh dill (finely chopped, plus extra to garnish)
  • 1 tablespoon extra virgin olive oil
  • 1 small clove garlic (minced)
  • 0.3 teaspoon black pepper (freshly ground)
  • 0.3 teaspoon smoked paprika (for a gentle background warmth)
  • 1 pinch sea salt (optional, the salmon and capers are already salty)

Instructions

  1. 1

    Preheat your oven to 190 degrees Celsius (375 degrees Fahrenheit). Make sure the rack is positioned in the centre of the oven so the frittata cooks evenly.

    Do not skip preheating. Starting with a hot oven is what gives the frittata a lightly golden top without overcooking the base.

  2. 2

    In a large mixing bowl, whisk together the egg whites and unsweetened almond milk until the mixture is slightly frothy. Season with black pepper, smoked paprika and a small pinch of sea salt if using. Set aside.

    Whisking until frothy, about 60 seconds by hand, incorporates a little air and results in a fluffier, lighter texture once cooked.

  3. 3

    Place a 25 cm (10 inch) oven-safe non-stick skillet over medium heat. Add the olive oil and allow it to warm for about 30 seconds. Add the minced garlic and sliced spring onions. Cook for 2 minutes, stirring occasionally, until softened and fragrant.

    Keep the heat at medium rather than high here. You want the spring onions to soften gently, not brown.

  4. 4

    Add the chopped baby spinach to the skillet. Stir and cook for 1 to 2 minutes until the spinach has wilted down completely. Spread the spinach and spring onion mixture evenly across the base of the pan.

    If there is any liquid released from the spinach, tilt the pan and blot it away with a piece of kitchen paper. Excess moisture can make the frittata watery.

  5. 5

    Scatter the smoked salmon pieces evenly over the vegetable base. Sprinkle over the chopped capers and half of the fresh dill.

  6. 6

    Pour the seasoned egg white mixture over the top, making sure it flows around all the ingredients and covers the base evenly. Scatter the crumbled feta across the surface.

    Do not stir once the egg whites are in the pan. You want the base to start setting while the top remains liquid before it goes into the oven.

  7. 7

    Cook on the stovetop over medium-low heat for 3 to 4 minutes, just until the edges begin to look set and opaque. The centre will still be very jiggly at this point.

    Running a silicone spatula gently around the edge of the frittata helps it release cleanly from the pan later.

  8. 8

    Carefully transfer the skillet to the preheated oven. Bake for 10 to 12 minutes, until the centre is fully set and no longer jiggles when you give the pan a gentle shake. The top should look just lightly golden.

    Check at 10 minutes. Egg whites can go from perfectly set to rubbery quickly, so it is better to check a little early.

  9. 9

    Remove the skillet from the oven using oven gloves and allow the frittata to rest in the pan for 5 minutes before slicing. This resting time helps it firm up so it cuts cleanly into neat wedges.

    Place the handle-side of the skillet somewhere visible when it comes out of the oven as a reminder that it is extremely hot.

  10. 10

    Scatter the remaining fresh dill over the top, slice into six equal wedges and serve warm. A few thin slices of cucumber or halved cherry tomatoes alongside make a lovely, simple accompaniment.

Pro Tips

  • Use a good quality wild smoked salmon for the best flavour. Farmed hot-smoked varieties work too, but cold-smoked wild salmon gives the cleanest taste.

  • If you only have whole eggs and want to save waste, use the leftover yolks to make a small batch of scrambled eggs or add one yolk back into the frittata for extra richness without significantly altering the nutrition.

  • An oven-safe cast iron or ceramic skillet works beautifully here if you do not have a non-stick one. Just make sure to grease it generously with olive oil first.

  • Do not overcook this frittata. The residual heat in the pan continues cooking the egg whites even after you pull it from the oven, so pulling it out when it is just barely set in the centre gives you a tender result.

  • For meal prep, let the frittata cool completely before slicing and storing. This prevents condensation from forming inside the container, which can make the texture watery.

Frequently Asked Questions

Can I make this smoked salmon and egg white frittata low carb recipe ahead of time?

Yes, absolutely. This frittata is brilliant for meal prep. Cook it fully, allow it to cool completely, then slice into wedges and store in an airtight container in the fridge for up to 4 days. Reheat individual slices in the microwave for 60 to 90 seconds.

Can I freeze egg white frittata?

You can freeze it, though the texture does change slightly on thawing. Egg whites can become a little watery after freezing. If you do freeze it, wrap individual slices tightly in cling film and freeze for up to one month. Thaw overnight in the fridge and reheat gently.

What makes this frittata low carb?

This recipe contains no starchy vegetables, no added sugar and no flour or grains. The ingredients, egg whites, smoked salmon, spinach, feta, spring onions and herbs, are all naturally very low in carbohydrates. Each serving has just 4 grams of total carbs.

Can I add whole eggs instead of just egg whites?

Yes. If you prefer a richer frittata, replace 4 of the egg whites with 2 whole eggs. This adds healthy fats and more of the fat-soluble vitamins found in yolks, though it will increase the calorie and fat count slightly per serving.

Is smoked salmon safe to eat without cooking it further?

Cold-smoked salmon sold from reputable retailers is safe to eat without further cooking for most healthy adults. In this frittata it is added to the hot pan and then the dish bakes in the oven, so it does warm through thoroughly. If you are pregnant or immunocompromised, speak with your doctor before consuming smoked salmon.

What can I serve with this frittata?

It is filling enough to eat on its own, but a simple side of sliced avocado, halved cherry tomatoes or a small green salad rounds out the plate nicely without adding significant carbohydrates. A squeeze of fresh lemon over the top just before serving is also lovely.

Variations

  • Dairy-Free Version

    Simply omit the reduced-fat feta and replace it with a tablespoon of nutritional yeast for a cheesy savouriness, plus a small handful of chopped sun-dried tomatoes for extra depth. The frittata is just as satisfying without the cheese.

  • Asparagus and Lemon Twist

    Add 8 thin asparagus spears, cut into 2 cm pieces, to the pan with the spring onions. Finish the frittata with a fine grating of lemon zest before serving. The lemon lifts all the flavours and pairs beautifully with the salmon.

  • Spicy Version

    Add a finely chopped small red chilli or a quarter teaspoon of dried chilli flakes to the pan with the garlic and spring onions. The mild heat cuts through the richness of the salmon and feta in a very pleasing way.

  • Courgette and Herb

    Grate one small courgette, squeeze out as much moisture as possible, and add it to the pan with the spinach. Swap the dill for a combination of fresh chives and flat-leaf parsley. This version adds extra fibre and a different flavour profile while keeping the carb count low.

Substitutions

  • Reduced-fat feta cheeseFull-fat goat cheese or ricotta (Both work well but will increase the calorie and fat content slightly. Goat cheese gives a creamier texture, while ricotta adds a mild, milky flavour.)
  • Unsweetened almond milkUnsweetened oat milk or plain water (Any unsweetened, unflavoured liquid works here. Water is the most neutral option if you want nothing competing with the salmon flavour.)
  • Fresh dillFresh chives or flat-leaf parsley (Dill is the most complementary herb for smoked salmon, but chives give a lovely mild onion note and parsley adds freshness. Use the same quantity.)
  • Baby spinachKale or rocket (Kale should be finely shredded and wilted for an extra minute or two as it is tougher than spinach. Rocket can be stirred in raw just before the egg whites are added, as it wilts quickly from the heat of the pan.)
  • Wild smoked salmonTinned wild salmon or hot-smoked salmon flakes (Tinned salmon is a more budget-friendly option with similar nutritional benefits. Break it into flakes and drain thoroughly before adding to the pan. Hot-smoked salmon gives a slightly firmer, flakier texture.)
  • CapersFinely chopped green olives (Green olives deliver a similar briny, salty punch to capers. Use the same quantity and chop them finely so they distribute evenly through the frittata.)

🧊 Storage

Allow the frittata to cool completely before storing. Slice into individual wedges and place in an airtight container. Refrigerate for up to 4 days. Reheat in a microwave on medium power for 60 to 90 seconds per slice, or in a low oven at 160 degrees Celsius for about 8 minutes.

📅 Make Ahead

This frittata is an excellent make-ahead breakfast. Prepare and bake it fully on the weekend, then store sliced portions in the fridge for quick weekday breakfasts. It also tastes great eaten at room temperature or cold, making it ideal for packed lunches.
