Spanish Omelet with Spinach & Salmon
A proper Spanish tortilla with a Nordic twist. Thin potato slices layered with cold-smoked salmon, wilted spinach, and cherry tomatoes, all sealed inside a slow-cooked egg base with olive oil. 572 kcal and 31g of protein in one pan, in 20 minutes.
The spinach here isn’t decoration. It’s one of the richest food sources of lutein, a carotenoid that filters blue light in your retina. Research has found that your body absorbs lutein significantly better from egg yolk than from spinach alone, because the yolk’s natural fat matrix acts as a delivery vehicle. This recipe cooks spinach directly inside eggs with olive oil, putting the lutein where the absorption happens.
Ingredients
- potato 0.5 pound
- smoked salmon 2 ounces
- cherry tomatoes 6
- eggs 2
- olive oil 1 tablespoon
- spinach 1 handful
Method
-
Scrub the potatoes clean, slice them thinly, and cook them in a small pot of water for 6-8 minutes until tender.
-
Cut the salmon and cherry tomatoes into small pieces. In a bowl, whisk the eggs with salt and pepper to taste.
-
Heat half of the olive oil in a pan and briefly cook the spinach until wilted, then remove from the heat.
-
In another pan, heat the remaining oil, layer half of the potato slices in the pan, and pour in half of the egg mixture.
-
Top with the salmon, spinach, and cherry tomatoes, then cover with the remaining potato slices.
-
Finally, pour the remaining whisked eggs over the top.
-
Let the egg mixture cook over low heat for about 8 minutes until set.
-
Serve the omelet on a plate.
Slice the potatoes as thin as you can, 2–3 mm thick. Thinner slices cook faster in the boiling water and layer more evenly in the pan, giving you a better set and a cleaner slice when you serve.
A separate trial found that eating eggs with carotenoid-rich vegetables boosted total carotenoid absorption over 8-fold compared to vegetables without eggs. The mechanism: egg yolk phospholipids help fat-soluble compounds like lutein dissolve into mixed micelles during digestion, making them available for your intestinal lining to absorb.

Is 31g of protein enough in one meal?
Research on per-meal protein suggests that 20–40g per meal is the range that maximizes muscle protein synthesis for most adults. At 31g, this omelet sits right in that window. The protein comes from two complete sources — eggs and smoked salmon — which together provide all essential amino acids.
Read the full evidence reviewWhy use smoked salmon instead of fresh?
Beyond the flavor, there’s a preservation advantage. Research found that cold smoking protects the omega-3 fats (EPA and DHA) in salmon far better than raw storage. Over 28 days, raw salmon lost nearly three times more EPA and DHA than cold-smoked salmon. The smoke compounds act as natural antioxidants that shield the fats from oxidation.
Can I flip the Spanish omelet?
You can, but you don’t have to. Traditional tortilla española is often flipped onto a plate and slid back into the pan to cook the top side. This recipe skips that — the low heat and 8-minute cook time sets the egg all the way through without flipping. If you want a golden top, slide the pan under a broiler for 2 minutes instead.
Do boiled potatoes really keep you fuller than other carbs?
In the most cited satiety study ever published, boiled potatoes scored 323% on the satiety index — the highest of all 38 foods tested, and more than three times higher than white bread. The effect is largely driven by the weight-per-calorie ratio: a 240-calorie portion of boiled potatoes weighs significantly more than the same calories from other carb sources, creating more stomach volume.
