🥗 Ingredients
The Base
- 2 thick slices Whole Grain Rye Bread (Rugbrød) (ensure 100% whole grain and no added sugar or molasses)
- 1 tablespoon Extra Virgin Olive Oil (for brushing the bread)
The Protein
- 1 tin (4.25 oz) Canned Sardines in Olive Oil (sustainably caught, bone-in for extra calcium)
- 1/2 teaspoon Lemon Juice (to brighten the fish)
The Herb Gremolata & Toppings
- 1/4 cup Fresh Flat-Leaf Parsley (finely chopped)
- 1 teaspoon Lemon Zest (from an organic lemon)
- 1/2 clove Garlic (minced into a paste)
- 2 pieces Radishes (sliced paper-thin)
- 1 small Shallot (sliced into thin rings)
- 2 tablespoons Apple Cider Vinegar (for quick-pickling the shallots)
- 1 teaspoon Capers (drained and patted dry)
Finishing Touches
- 1 pinch Flaky Sea Salt (like Maldon)
- 1/4 teaspoon Cracked Black Pepper (freshly ground)
- 2 teaspoons Dijon Mustard (ensure no sugar added)
- 1/4 cup Microgreens (optional, for garnish)
👨🍳 Instructions
-
1
Begin by quick-pickling the shallots: In a small bowl, submerge the shallot rings in apple cider vinegar. Let them sit for at least 10 minutes to soften the bite and turn them a vibrant pink.
-
2
Prepare the gremolata by combining the finely chopped parsley, lemon zest, and the minced garlic paste in a small ramekin. Stir well to release the aromatic oils.
-
3
Open the tin of sardines and carefully drain about half of the oil. Transfer the sardines to a small plate and gently flake them into large chunks, drizzling with 1/2 teaspoon of lemon juice.
-
4
Preheat a cast-iron skillet or heavy pan over medium-high heat. Lightly brush both sides of your rye bread slices with olive oil.
-
5
Place the rye bread in the hot skillet. Toast for about 2-3 minutes per side until the edges are crispy and the center is warm and firm.
-
6
While the bread is hot, spread a thin, even layer of Dijon mustard across one side of each slice.
-
7
Layer the thinly sliced radishes over the mustard. This creates a crunchy, peppery barrier that prevents the bread from getting soggy.
-
8
Arrange the sardine chunks over the radishes, distributing them evenly across both slices of toast.
-
9
Drain the pickled shallots from the vinegar and scatter them over the sardines, followed by the capers.
-
10
Generously sprinkle the herb gremolata over the top of the assembly.
-
11
Finish with a pinch of flaky sea salt, a healthy crack of black pepper, and a handful of fresh microgreens if using.
-
12
Serve immediately while the bread is still warm and the sardines are at room temperature for the best flavor profile.
💡 Chef's Tips
Always look for sardines packed in olive oil or water rather than soybean oil for better flavor and health benefits. If you find sardines too intense, try 'bristling' sardines which are smaller and milder. To ensure the recipe is truly sugar-free, check the label on your rye bread; many commercial brands use molasses or honey for color and sweetness. Rubbing a raw garlic clove directly onto the toasted bread before spreading the mustard adds an extra layer of savory depth. If you prefer a creamy element, a dollop of full-fat Greek yogurt or labneh (sugar-free) works beautifully under the sardines.
🍽️ Serving Suggestions
Pair with a hot cup of black pour-over coffee or a strong Earl Grey tea. Serve alongside a soft-boiled egg (6-minute egg) for extra protein. A side of sliced cucumber seasoned with dill and white vinegar complements the richness of the fish. For a brunch setting, serve with a chilled glass of tomato juice spiked with lemon and black pepper.
