Step‑by‑Step Instructions for Ensalada de San Isidro
Step 1: Prepare Dressing
In a small bowl, whisk together 1/4 cup of extra virgin olive oil, 2 tablespoons of sherry vinegar, 1 clove of grated garlic, 2 tablespoons of finely chopped fresh parsley, and a pinch of sea salt and black pepper. Mix rapidly for around 30 seconds until the mixture is well combined and emulsified. Set the dressing aside to allow the flavors to meld while you prepare the rest of the salad.
Step 2: Lettuce Prep
Take a head of romaine lettuce and separate the leaves. Wash them thoroughly under cool water to remove any dirt or grit. After rinsing, dry the leaves using a salad spinner or by patting them gently with a clean kitchen towel. Once dried, chop the romaine into bite-sized pieces, about 1 inch, and place them into a large serving bowl.
Step 3: Slice Vegetables
With your prepared romaine base ready, thinly slice 1/2 a red onion and halve 1 cup of cherry tomatoes. As you cut, aim for consistent thickness to ensure even distribution of flavors in your Ensalada de San Isidro. Add the sliced onions and halved tomatoes directly to the bowl with the chopped romaine, creating a colorful mixture.
Step 4: Assemble Salad
Gently toss the romaine, sliced onions, and cherry tomatoes together in the bowl. This combination of fresh vegetables creates a vibrant base for your salad. Ensure that the ingredients are evenly mixed, creating an inviting presentation and ensuring each bite is packed with flavor.
Step 5: Add Protein and Olives
Open a can of tuna in olive oil, draining it lightly. Flake the tuna with a fork and gently fold it into the salad mixture along with 1/3 cup of green pimento stuffed olives and 1/3 cup of black pitted olives. For added creaminess, slice 2 hardboiled eggs in half and add them on top, creating a visually appealing layer on your Ensalada de San Isidro.
Step 6: Season
Sprinkle the mixed salad with a pinch of sea salt and freshly cracked black pepper to taste. Then, drizzle the prepared dressing over the top, ensuring an even distribution. Gently toss the entire salad again to combine all ingredients thoroughly, making sure the lettuce is well coated without bruising the delicate leaves. Serve immediately for optimal freshness and flavor.

Expert Tips for Ensalada de San Isidro
-
Dry Lettuce Thoroughly: Use a salad spinner or dishcloth to remove excess moisture; soggy lettuce can ruin the salad’s texture.

Adjust Seasoning Smartly: Taste as you go; salt levels may vary depending on the type of olives used, so season gradually for the perfect balance.

Ensalada de San Isidro Recipe FAQs
How do I choose ripe ingredients for Ensalada de San Isidro?

Can I freeze Ensalada de San Isidro?
Not recommended! Freezing this salad can lead to a mushy texture once thawed, especially for the lettuce and tomatoes. Instead, I suggest enjoying it fresh and making only what you plan to eat.

What should I do if my salad ingredients are getting soggy?
No worries! If you find your salad components becoming soggy, start by ensuring your lettuce is completely dry after washing. Use a salad spinner or a clean dish towel.

If you’re serving this for guests with gluten allergies, rest assured that it’s naturally gluten-friendly. Always check labels on canned items, like olives and tuna, to ensure they meet dietary requirements.
How long can I leave the salad out at room temperature?
To ensure safety, avoid leaving the salad out for more than 2 hours, especially due to ingredients like tuna and eggs. If it’s hot or in warm conditions, it’s best to refrigerate any leftovers sooner to keep them safe for the next meal. Enjoy your Ensalada de San Isidro fresh and at its best!
