Sardine Avocado Toasts

Sardine Avocado Toasts turn a few pantry staples into a bright, satisfying meal with restaurant-level flavor. Crisp, garlicky sourdough supports a generous layer of creamy lemon-Dijon avocado and tender olive-oil sardines. Meanwhile, a quick shallot, caper, parsley, and lemon relish cuts through the richness with just enough tang and gentle heat.

These toasts are easy enough for a weekday lunch, yet they also feel right at home at brunch. Every layer has a purpose: crunchy bread, silky avocado, savory fish, and a fresh, punchy finish. Better still, everything comes together in about 20 minutes without complicated prep. Serve the toasts immediately while the bread is warm and crisp. A lemon wedge on the side is all they need, although a simple leafy salad turns them into a complete light meal.

Recipe Yield: 4 servings

INGREDIENTS

4 large slices rustic sourdough bread, about 1/2-inch thick
2 cans (4.25 oz each) sardines packed in olive oil, carefully drained
2 medium ripe avocados
1 small garlic clove, halved
1 small shallot, very thinly sliced, about 1/4 cup
1 tbsp red wine vinegar
1/2 tsp honey
2 tbsp finely chopped fresh flat-leaf parsley
1 tbsp capers, drained and roughly chopped
1 tsp finely grated lemon zest
1/8 tsp red pepper flakes, plus more for serving
3 tbsp extra-virgin olive oil, divided
1 1/2 tbsp fresh lemon juice
1 tsp Dijon mustard
1/4 tsp kosher salt, plus more as needed
1/4 tsp freshly ground black pepper
Lemon wedges, for serving

INSTRUCTIONS

1. Pickle the shallot:
Combine the shallot, vinegar, and honey in a small bowl. Let stand for 10 minutes, tossing once or twice.

2. Make the relish:
Using a fork, transfer the shallot to another small bowl. Add 1 tsp pickling liquid, parsley, capers, lemon zest, red pepper flakes, and 1 tbsp olive oil. Stir gently.

3. Mash the avocado:
Mash the avocados with the lemon juice, Dijon, salt, and black pepper. Leave a few small pieces for texture, then taste and adjust the salt if needed.

4. Toast the bread:
Brush both sides of the bread evenly with the remaining 2 tbsp olive oil. Toast in a skillet over medium heat for 2–3 minutes per side, working in batches if needed. Rub the warm toast lightly with the cut garlic.

5. Assemble the toasts:
Spread the avocado mixture generously over each toast. Arrange the sardines on top, keeping them mostly intact. Spoon over the shallot-caper relish and serve immediately with lemon wedges.

HELPFUL TIPS TO PERFECT THIS RECIPE

• Toast the bread deeply: The sourdough should be crisp and well browned so it stays sturdy beneath the avocado, sardines, and relish.
• Handle the sardines gently: Lift them from the cans with a fork rather than pouring them into a strainer. This helps preserve their attractive shape and tender texture.
• Season after tasting: Sardines, capers, and Dijon vary in saltiness. Taste the avocado before adding extra salt so the finished toast stays balanced rather than briny.
• Prepare only the relish ahead: The shallot-caper relish can be refrigerated for up to one day. However, mash the avocado and assemble the toasts immediately before serving.
