Chicken Caesar Salad

What this is

Grilled chicken, romaine, parmesan, anchovy dressing, croutons. The version people order when they think they are being sensible, and then regret because it arrives drowned.

Made properly it is one of the better meals on this list: high protein, a genuine amount of leafy vegetable, and a dressing that is not the villain it has been made into.

There are two pieces of research here that will change how you build it, and one about the anchovies that most people skip out of squeamishness.

Ingredients

For 2 servings

2 chicken breasts, about 180 g each 2 romaine hearts, chopped 40 g parmesan, shaved 2 thick slices sourdough, torn into chunks 2 tbsp olive oil for the croutons

Dressing 4 anchovy fillets in oil, drained 1 egg yolk 1 clove garlic 2 tsp Dijon mustard 1 tbsp lemon juice 4 tbsp olive oil 20 g parmesan, finely grated Black pepper

Optional: half an avocado, cherry tomatoes, a soft-boiled egg

Method

1. Heat the oven to 200C. Toss the torn sourdough with olive oil and salt, spread on a tray and bake 10 to 12 minutes until golden. Shop-bought croutons are a waste of the dish.

2. Flatten the chicken breasts slightly so they cook evenly. Season and grill or pan-cook over medium-high heat, 5 to 6 minutes a side depending on thickness, until just cooked through. Rest 5 minutes before slicing.

3. For the dressing, mash the anchovies and garlic to a paste. Whisk in the egg yolk, mustard and lemon.

4. Add the olive oil slowly, whisking constantly, until it thickens and emulsifies. Stir in the grated parmesan and plenty of black pepper.

5. Toss the romaine with the dressing, using less than you think. The leaves should be coated, not swimming.

6. Add the croutons and shaved parmesan, then the sliced chicken on top.

7. Eat immediately. A dressed salad has a short life.

The dressing is not the problem

This is the finding that should change how you order.

A review examined the health functions of vegetables specifically when consumed as a salad, on the grounds that while there are many reports on vegetable intake improving health, no comprehensive review had summarised what happens when they are eaten in salad form with the condiments that come with it.

That is a real gap. Vegetables in a laboratory and vegetables under dressing are different exposures.

The review covers the effects of vegetable salads on amounts of vegetable intake, on lifestyle-related diseases, and on the absorption of specific nutrients through mayonnaise, as well as the effects of the order in which vegetable salad and carbohydrates are consumed.

Two things in that list are worth pausing on.

First, absorption of specific nutrients through mayonnaise. The fat in a dressing is not simply added calories sitting alongside the vegetables; fat-soluble compounds in leaves need fat present to be absorbed. A dry salad is not the optimised version of a dressed one.

Second, the order in which salad and carbohydrates are consumed has been studied as a variable in its own right. Eating your vegetables before your carbohydrate is not a wellness ritual somebody invented, it is something researchers measure.

The practical version for this dish: dress the leaves properly with a real olive oil emulsion rather than a fat-free dressing, and if you are having bread alongside, eat the salad first.

This is a narrative review summarising the salad literature rather than a trial, and it addresses mayonnaise specifically for the absorption question. It establishes that these are studied variables; it does not quantify the effect for this recipe.

Keep the anchovies

The anchovies are the ingredient people ask to leave out, and they are doing more than seasoning.

A study developing anchovy-based products describes why: anchovies are rich in omega-3 fatty acids, high-quality protein, vitamins A and D, and minerals, making them a valuable food source for public health.

The researchers incorporated anchovy into three popular fast-food items, toast, burger and pizza, then measured nutritional composition and sensory acceptance. The anchovy-enriched toast reached the highest crude protein content at 18.64 percent and the highest crude ash at 4.38 percent, while the anchovy burger had the highest crude fat at 10.82 percent.

On taste, the point that matters for anyone squeamish: panellists generally accepted all the products.

Four anchovy fillets in a dressing for two people is a small amount of fish, but it is not nothing, and it is the difference between a Caesar dressing and salted mayonnaise. Mashed into a paste with garlic they do not taste of fish, they taste of savoury depth.

This was a food product development study measuring composition and sensory scores in manufactured items, not a study of dressing or of health outcomes. It is included for what anchovies contain and for the acceptance finding, not as evidence about this recipe.

Why the leaves themselves vary

One thing worth knowing when you buy salad, because not all romaine is equivalent.

A review synthesised how greenhouse environmental conditions shape nitrate accumulation, nutritional quality and shelf life in lettuce, spinach and rocket.

Light intensity and temperature exert the strongest influence, regulating carbon assimilation, nitrate reductase activity and metabolic homeostasis.

And the direction is consistent: adequate, well-distributed light at moderate temperatures enhances chlorophyll, carotenoids, vitamin C and phenolics while lowering nitrate levels. Low light or excessive heat suppress nitrate reduction, dilute pigments and antioxidants, and accelerate deterioration.

So the growing conditions determine both the nutritional content and how long the leaves last in your fridge, through carbohydrate reserves, antioxidant capacity, membrane stability and calcium-mediated tissue integrity.

The practical read is simple and not a purchasing rule: darker, firmer, more vividly coloured leaves are a reasonable proxy for better growing conditions, and limp pale leaves are telling you something real rather than just looking sad.

That proxy is my inference. This review addresses greenhouse production science rather than consumer selection, and it concerns lettuce, spinach and rocket rather than romaine specifically.

Storage and swaps

Dress it at the table, not in advance. Undressed components keep 3 days separately; a dressed salad lasts about twenty minutes.

The dressing keeps 3 days in the fridge in a jar. It contains raw egg yolk, so keep it cold and use it promptly, and skip the raw yolk version if you are pregnant or immunocompromised.

Swap chicken for grilled prawns, leftover steak or a tin of good tuna.

Swap romaine for little gem, which holds dressing better, or kale massaged with a little of the dressing first.

And make the croutons yourself. Ten minutes, and it is the difference between the dish being good and being a bowl of leaves.
