Creamy Spinach Soup with Boiled Eggs (Nordic Classic)

Published: 7/27/2026

“Pinaattikeitto” is a foundational 20-minute weekday meal (arkiruoka). The technical objective is a smooth, stable béchamel-based soup.

Ingredients (4 servings)

• 10 oz (285 g) frozen chopped spinach (thawed) or fresh spinach (finely minced)
• 4 cups (960 ml) whole milk
• 2 tbsp (28 g) unsalted butter
• 3 tbsp (24 g) all-purpose flour
• 1/2 tsp (3 g) salt
• 1/4 tsp (0.5 g) ground nutmeg
• 4 large hard-boiled eggs

Instructions

1. In a heavy-bottomed pot, melt the butter over medium heat. Whisk in the flour to form a roux. Cook for 60 seconds, whisking constantly to remove the raw flour taste without coloring the roux.
2. Incremental Mixing: Add the milk in 1/2 cup increments, whisking vigorously after each addition. This technique prevents the roux from clumping and ensures a velvety texture.
3. Once all the milk is incorporated, add the spinach and bring the soup to a very gentle simmer.
4. Simmer for 10 minutes, stirring frequently to prevent the milk solids from settling.
5. Season with salt and nutmeg.
6. Slice the hard-boiled eggs in half. Ladle the soup into bowls and place two egg halves, yolk-side up, in the center of each serving.

Pro Tips

• Scorch Prevention: Use a heavy-bottomed stainless steel or enameled cast iron pot. Thin-walled pots create hot spots that will cause the milk proteins to burn and impart a bitter flavor to the soup.
• Easy-Peel Technique: For the garnish, boil eggs for 9.5 minutes, then immediately plunge them into an ice bath for 5 minutes. This creates a clean separation between the membrane and the shell.
