Baby Spinach Salad with Avocado, Tomato and Lime Dressing

When I need a quick side dish for burgers, grilled chicken, or a summer barbecue, this baby spinach salad is one of the recipes I come back to regularly. It uses simple ingredients, comes together in minutes, and can be made ahead of time without becoming soggy.

If you’re looking for great options for summer meals, this easy salad pairs well with my Mediterranean Bulgur and White Bean Summer Salad or Grilled Potato and Corn Salad with Green Goddess.

This baby spinach salad is made with fresh baby spinach, avocado, tomato, red onion, and a homemade lime dressing. The dressing is bright and tangy, while the avocado adds enough richness to balance the citrus and tie everything together.

Unlike many avocado salads that need to be eaten immediately, this baby spinach salad holds up surprisingly well in the refrigerator. The lime dressing coats the avocado before it is added to the salad, helping slow browning while allowing the flavours of the avocado, tomato, and red onion to mingle together as the salad sits.

The dressing is intentionally bold. Fresh lime juice, olive oil, celery seed, and a few drops of Tabasco create a flavour that becomes even better after a day or two in the refrigerator. By the second or third day, the avocado, tomato, red onion, and lime dressing begin to develop flavours that remind me a little of fresh guacamole, while the spinach continues to provide a fresh base for the salad.

Quick Answer

This easy spinach salad recipe combines fresh baby spinach, avocado, tomato, and red onion with a homemade lime dressing. It makes a perfect side salad for barbecues and cookouts, but it’s also substantial enough to serve as a light lunch or light meal.

One of the reasons I coat the avocado in the lime dressing before adding it to the salad is to help slow browning during storage. The avocado stayed fresh for several days in the refrigerator, and by the third day the avocado, tomato, red onion, and dressing had developed a flavour that reminded me a little of fresh guacamole.

Why You’ll Love This Baby Spinach Salad

Make-Ahead Friendly: The lime dressing helps slow avocado browning, allowing the salad to stay fresh longer than many avocado-based salads.

Light Lunch Option: This baby spinach salad works well on its own for lunch or paired with grilled chicken for a more filling meal.

Homemade Lime Dressing: The dressing adds a bright citrus flavour with just a small amount of heat from the Tabasco sauce.

How to Make Baby Spinach Salad with Avocado, Tomato and Lime Dressing

Begin by preparing the dressing. Add the olive oil, fresh lime juice, Tabasco sauce, black pepper, salt, celery seed, and sugar to a small mixing cup or jar. Use an immersion blender to blend the ingredients until the dressing becomes smooth and lightly emulsified.

Wash spinach thoroughly, even if using pre-washed baby spinach. Remove any tough stems and pat the leaves dry with paper towels or use a salad spinner before transferring them to a large bowl.

Dice the tomato and red onion finely so they distribute evenly through the salad.

Cut the avocado into small cubes. Since the dressing is made in a small bowl or blending cup, transfer the avocado cubes into the dressing after blending. Gently stir until the avocado is coated before adding it to the salad. This helps slow browning and lets the lime dressing cling to the avocado before it touches the spinach.

Add the tomato, red onion, and dressed avocado with the dressing to the bowl of spinach. Gently toss until the salad ingredients are evenly coated. Refrigerate for at least an hour before serving to allow the flavours to blend together.

This salad is best served chilled for at least an hour or you can refrigerate until needed.

Ingredients 

This baby spinach salad uses a handful of fresh vegetables and a homemade lime dressing that ties everything together.

Baby spinach: Baby spinach forms the base of the salad. Remove any tough stems, wash if needed, and pat dry thoroughly. Excess moisture can dilute the dressing and make the salad watery. Fresh baby spinach has a milder flavour and more tender texture than mature fresh spinach, making it a good choice for salads where you want the dressing and vegetables to remain the focus.

Tomato: The tomato adds freshness, colour, and a little natural sweetness. Dicing it finely helps distribute the flavour throughout the salad instead of creating large chunks.

Avocado: Avocado adds richness and balances the tangy lime dressing. The avocado is coated in dressing before being added to the salad, which helps slow browning and distributes the lime flavour throughout the dish.

Red onion: Red onion provides a bit of sharpness that complements the avocado and tomato. Dicing it finely prevents it from overpowering individual bites.

Homemade Lime Dressing

Unlike many salad dressings that rely on vinegar, this homemade dressing uses fresh lime juice for acidity. The combination of lime juice, celery seed, olive oil, and a few drops of Tabasco creates a dressing that stands up well to avocado and tomato without overwhelming the baby spinach.

Olive oil: Olive oil forms the base of the dressing and creates a smooth emulsion when blended.

Fresh lime juice: This key ingredient provides the bright citrus flavour that defines this dressing.

Tabasco sauce: A few drops add gentle heat without making the dressing spicy.

Black pepper: Adds mild seasoning and depth.

Salt: Helps balance the acidity of the lime juice.

Celery seed: Celery seed gives the dressing a subtle savoury flavour that works especially well with the tomato and avocado.

White sugar: A small amount of sugar balances the tartness of the lime juice.

Substitutions and Add-Ins for Baby Spinach Salad 

This baby spinach salad is flexible, but a few ingredients play an important role in its overall flavour.

Baby spinach: Spring mix or romaine lettuce can be substituted, although the flavour and texture will change. Baby spinach provides the mild base that makes the dressing stand out.

Tomato: Cherry tomatoes or grape tomatoes can be substituted. Dice them into small pieces for similar distribution throughout the salad.

Avocado: Avocado should not be omitted. It balances the acidity of the dressing and is a major part of the salad’s flavour and texture.

Red onion: Sweet onion can be substituted for a milder flavour.

Olive oil: Avocado oil can be substituted with little change to the finished dressing.

Fresh lime juice: Freshly squeezed lime juice is strongly recommended. Bottled juice will work in a pinch but lacks the same fresh flavour. If you don’t have limes you can use lemon juice but the dressing with have a very different flavor profile. 

Tabasco sauce: Other vinegar-based hot sauces can be substituted, although the flavour will vary slightly.

Black pepper: Freshly ground black pepper or pre-ground pepper both work well.

Salt: Table salt or kosher salt can be used.

Celery seed: Celery seed contributes a distinctive flavour to the dressing. If omitted, the dressing will still work but will lose some of its character.

White sugar: Honey or maple syrup can be substituted, although they will add a slightly different flavour profile.

Expert Tips, Serving and Storing Suggestions

Tip #1: Dress the avocado first: Coating the avocado with dressing before adding it to the salad helps slow browning and distributes the lime flavour throughout the salad.

Tip #2: Dry the spinach well: Excess moisture can water down the dressing and reduce the overall flavour of the salad.

Tip #3: Adjust the dressing to taste: This dressing is intentionally tangy. If you prefer a milder dressing, add a little extra sugar or reduce the lime juice slightly.

Tip #4: Dice ingredients small: Small pieces of tomato and red onion help create a more balanced bite and prevent large chunks from overwhelming the spinach.

This baby spinach salad with homemade dressing makes a perfect side salad, for grilled Italian sausage, barbecue chicken, pork chops, or steak. It can also be served as a light lunch or main course when topped with grilled steak strips or chicken for a more substantial meal.
