Vegan Lohikeitto – Finnish Salmon Soup with Carrot Lox

What Does Lohikeitto Mean?
The Finnish name is wonderfully straightforward. "Lohi" means salmon and "keitto" means soup. Lohikeitto therefore literally translates as "salmon soup". It is one of Finland's best-known traditional soups and is especially appreciated as a warming, comforting meal.

What Makes Traditional Finnish Lohikeitto Special?
Traditional Lohikeitto is made with relatively few ingredients: fresh salmon, potatoes, leek, cream, dill and often carrots. Some recipes include allspice berries and bay leaves for a subtle aromatic background. The result is a mild, creamy soup in which the individual ingredients remain recognizable rather than being overwhelmed by spices.

Salmon and Carrots – Two Ingredients Become One
Traditional Finnish Lohikeitto often contains both salmon and carrots. In this vegan interpretation, carrots take on two different roles. Two carrots remain in the soup as vegetables, while three larger carrots are transformed into homemade carrot lox.

This means the original salmon ingredient can be replaced entirely without introducing a completely different vegetable. The carrots were already part of the traditional flavor combination – they simply receive a second job.

Fresh Salmon or Smoked Salmon?
Authentic Finnish Lohikeitto is generally prepared with fresh salmon rather than smoked salmon. The fish is usually added towards the end of cooking so it stays tender.

This vegan version takes a slightly different approach by using smoky carrot lox. The result is not an exact reproduction of traditional Lohikeitto, but a plant-based interpretation that combines the soup's familiar ingredients with the distinctive flavor of homemade carrot lox.

What Exactly Is Carrot Lox?
Carrot lox is a plant-based alternative inspired by cured or smoked salmon. Thin carrot ribbons are softened and then marinated with ingredients that create salty, smoky, savory and slightly maritime flavors.

The name "lox" traditionally refers to cured salmon, although the term is often associated with smoked salmon in everyday food culture. Carrot lox borrows the idea of delicate, seasoned slices without using fish.

Why Does Carrot Lox Taste Surprisingly Similar to Smoked Salmon?
Carrots do not naturally taste like salmon. Their transformation comes from a combination of texture and carefully balanced flavors.

Blanching softens the ribbons, making them flexible and delicate. Soy sauce contributes salt and umami, nori provides marine notes, and liquid smoke adds the characteristic smoky aroma. Lemon juice and apple cider vinegar bring acidity, while maple syrup balances the marinade.

The finished carrot lox has its own distinct character rather than being chemically or nutritionally identical to fish.

Why Is Marinating Time So Important?
Marinating allows the carrot ribbons to absorb flavors from the surrounding liquid. Salt, acidity and aromatic ingredients gradually influence the taste of the softened carrot surfaces.

A short marinating time may produce a pleasant result, but the flavor generally becomes more developed after 12–24 hours. Keeping the ribbons in a covered container in the refrigerator helps maintain food safety and prevents them from drying out.

What Is Liquid Smoke?
Liquid smoke is a concentrated flavoring produced by capturing and condensing smoke from burning wood under controlled conditions. It is used to introduce smoky aromas without directly smoking the food.

Because its intensity varies between products, a small quantity is usually sufficient. Starting with half a teaspoon and adjusting gradually helps avoid an overpowering flavor.

Why Use Nori Flakes?
Nori is an edible seaweed commonly used in Japanese cuisine. Its distinctive savory and marine flavor makes it useful in plant-based alternatives to fish and seafood.

In this recipe, nori appears in both the carrot lox marinade and the soup broth, creating a subtle connection between the two components.

Seaweed products can vary in iodine content. Nori generally contains less iodine than some other seaweeds, such as kombu, but quantities and nutritional values still depend on the product.

Why Soy Sauce and Lemon Work So Well Together
Soy sauce provides saltiness and umami, while lemon contributes brightness and acidity. Together, they create a savory flavor profile that works particularly well with dill, seaweed and the natural sweetness of carrots.

Since soy sauce already contains salt, taste the finished soup before adding additional seasoning.

Why Is Fresh Dill Essential?
Dill is one of the defining flavors of Finnish Lohikeitto. Its fresh, grassy and slightly sweet aroma complements the creamy broth and the traditional combination of potatoes and salmon.

In this vegan version, dill also balances the smoky marinade and adds freshness to the carrot lox. Adding most of it near the end of cooking helps preserve its aroma and color.

Why Use Waxy Potatoes?
Waxy potatoes contain relatively little starch compared with floury varieties and tend to hold their shape during cooking. This makes them especially suitable for soups in which tender, recognizable potato pieces are desired.

Cutting the potatoes into similar-sized cubes helps them cook evenly.

Why Use Allspice and Bay Leaves?
Allspice berries contribute warm, aromatic notes reminiscent of several familiar spices, while bay leaves add subtle herbal depth.

Both ingredients should remain in the background rather than dominating the soup. Remove the bay leaves before serving and remove the allspice berries if preferred.

Oat Cream and Oat Drink – A Dairy-Free Alternative
Traditional Lohikeitto often contains dairy cream. Oat cream provides a rich, smooth texture, while unsweetened oat drink makes the broth lighter without sacrificing its comforting character.

Choose unsweetened products without vanilla flavoring. Their fat and protein contents vary between brands and influence the final consistency of the soup.

Carrots and Beta-Carotene
Carrots are well known for their beta-carotene content. Beta-carotene is a carotenoid pigment responsible for much of their orange color, and the body can convert it into vitamin A as needed.

Vitamin A supports normal vision, immune function and the maintenance of healthy skin and mucous membranes. Including some dietary fat, such as the olive oil in the marinade, can support the absorption of fat-soluble carotenoids.

Does Carrot Lox Provide the Same Nutrients as Salmon?
No. Carrot lox can reproduce some of the culinary experience of smoked salmon, but its nutritional composition is very different.

Salmon is naturally rich in protein and provides the long-chain omega-3 fatty acids EPA and DHA. Carrots contain far less protein and do not provide comparable amounts of EPA and DHA.

For a balanced vegan diet, reliable sources of protein and omega-3 fatty acids should come from other foods. Legumes, tofu, tempeh and soy products are useful protein sources, while algae-based supplements can provide EPA and DHA directly.

What About Overfishing?
Choosing carrot lox instead of salmon reduces the demand for fish in this particular meal. This can be one way to enjoy familiar flavors while avoiding direct consumption of salmon.

However, salmon sustainability is more complex than a simple distinction between sustainable and unsustainable fish. Wild salmon populations face different pressures depending on the region, including fishing, habitat degradation and climate change. Farmed salmon raises separate environmental and animal-welfare questions.

Plant-based alternatives offer a practical way to reduce reliance on fish without giving up the pleasure of preparing flavorful, satisfying meals.

Why Fish-Free Does Not Automatically Mean Nutritionally Complete
A vegan replacement can be delicious and environmentally appealing without matching every nutrient provided by the animal-based ingredient.

Carrot lox is primarily a flavorful vegetable preparation rather than a concentrated protein source. This Lohikeitto is rich in vegetables and carbohydrates from potatoes, but its protein content is relatively modest.

A balanced plant-based diet should include sufficient protein, vitamin B12 and other essential nutrients across the day rather than expecting every individual recipe to provide everything.

What About Cholesterol?
Carrots, potatoes and other unprocessed plant foods naturally contain no cholesterol. The plant-based ingredients used in this recipe also avoid the cholesterol found in animal-derived cream and salmon.

However, dietary cholesterol is only one factor affecting blood cholesterol. The amount and type of fat consumed, especially saturated fat, also matter.

HDL, LDL and the Role of Dietary Fat
LDL particles transport cholesterol through the bloodstream, and elevated LDL cholesterol is a well-established cardiovascular risk factor. HDL particles participate in cholesterol transport away from peripheral tissues, but a higher HDL value alone does not necessarily guarantee better cardiovascular health.

Replacing some saturated fats with unsaturated fats can help lower LDL cholesterol. Olive oil, used in the carrot lox marinade, provides predominantly unsaturated fatty acids.

Plant-based cream products vary in their fat composition, so checking the ingredients and nutrition label remains useful.

Zero Waste – Use the Whole Leek
Do not throw away the dark-green leaves of the leek. The tender white and light-green parts are ideal for Lohikeitto, but the tougher dark-green leaves can still be useful.

Wash them thoroughly to remove trapped soil, then freeze them with other clean vegetable trimmings. Once you have collected enough, use them to prepare homemade vegetable stock.

Zest First, Juice Second
When using fresh lemons, grate the zest before squeezing out the juice. It is much easier to remove the zest from a whole lemon than from an already squeezed half.

Use only the colored outer layer and avoid the bitter white pith. Leftover zest can be frozen in a small airtight container for future recipes.

What Can You Do with Leftover Carrot Lox?
Carrot lox is delicious beyond this Finnish soup. Serve it on toasted bread with vegan cream cheese, add it to bagels with cucumber and dill, or use it as a topping for savory breakfast dishes.

Keep unused carrot lox refrigerated in a clean, airtight container and use it promptly. Do not leave it at room temperature for extended periods.

Can Lohikeitto Be Prepared in Advance?
The vegetable soup can be prepared ahead and refrigerated promptly. Store any unused carrot lox separately so it retains its texture and flavor.

When reheating, warm the soup gently rather than boiling it vigorously. Add the carrot lox only after reheating and finish with fresh dill and lemon zest.
