Ingredients for 2 servings

2 servings

Check off ingredients as you go.

Contains eggs, gluten, milk. Check the labels on packaged ingredients:

  • Gruyère. Traditional Gruyère is made with animal rennet, so it is not vegetarian.
  • sourdough bread. Bread often contains soya and can contain milk, egg or sesame; check the label.

Cooking steps

  1. Heat the oven to 180°C / 350°F (160°C fan).

  2. Warm the oil in a wide pan over medium heat and add the spinach in handfuls, letting each wilt before the next goes in. It takes 3 to 4 minutes.

  3. Tip the spinach into a sieve and press it hard with the back of a spoon until it stops dripping. This is the step the dish depends on.

  4. Divide the spinach between two shallow ovenproof dishes and make two hollows in each. Crack an egg into each hollow.

  5. Scatter over the grated Gruyère and the thyme leaves. Bake for 12 to 15 minutes.

    Cooked when: the whites are set and the yolks are firm.

  6. Toast the sourdough bread while the eggs bake and serve straight from the dishes.

The useful detail

Press the spinach hard before the eggs go on. Spinach is almost all water, and any you leave behind collects under the eggs and turns the dish into soup.

Make it work for you

One serving is One dish of two eggs over half the spinach, with a slice of toast. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Cheddar instead of Gruyère

    Sharper and oilier when it melts. Use the same weight.

    Per serving: about the same energy, about 1 g less protein, about the same fat.

  • Frozen spinach, 200 g, thawed

    Squeeze it even harder than fresh; it holds more water. Nutrition is close enough not to recalculate.

  • Gluten-free bread instead of sourdough

    No difference to the baked eggs.

    Allergens: Needed if you avoid gluten.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

A hot breakfast built on eggs and cheese rather than cereal, with the spinach carrying most of the fibre and the toast the carbohydrate.

Show calculation notes

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 2. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Best eaten straight away. If you have to keep one, cool it, cover and refrigerate within 2 hours, and eat within 3 to 4 days.
Reheating
Reheat until it reaches 74°C / 165°F, steaming hot throughout. The yolk will firm up completely.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
