Americas Test Kitchen Kale Caesar Salad

In the world of culinary science and home cooking, few names command as much respect as America’s Test Kitchen (ATK). Their rigorous testing methods and dedication to finding the “best” version of a recipe have transformed how we approach everyday staples. One of the most significant contributions to the modern salad repertoire is their approach to the Kale Caesar Salad. For years, the Caesar salad was strictly the domain of Romaine lettuce—crisp, watery, and arguably a mere vessel for the rich dressing. However, the rise of kale as a superfood brought a culinary challenge: how do you turn a fibrous, tough, and sometimes bitter leaf into a salad that is just as luxurious and palatable as its predecessor?

The challenge with raw kale is its texture. Unlike tender lettuces, kale possesses a sturdy cellular structure designed to withstand frost and wind. When eaten raw without proper treatment, it can feel like chewing on leather. The genius of the Test Kitchen approach lies in the “tenderization” process. This isn’t just about tossing ingredients in a bowl; it is about using mechanical and chemical reactions to break down the vegetable’s toughness.

This article explores a recipe inspired by the meticulous techniques popularized by America’s Test Kitchen. We focus on Lacinato kale (also known as Tuscan or Dinosaur kale), which offers a pebbled texture and a sweeter, earthier flavor profile than curly kale. The secret lies in the preparation: slicing the leaves into thin ribbons and massaging them, often with a vinaigrette or a portion of the dressing, to soften the waxy cuticle of the leaf. Combined with garlic-infused homemade croutons and a dressing that balances the umami punch of anchovies with the brightness of fresh lemon juice, this salad transforms a health food staple into a crave-worthy indulgence.

Whether you are looking for a robust side dish for a steak dinner or a substantial main course, this scientifically optimized Kale Caesar Salad offers the perfect balance of crunch, creaminess, and acidity. Below, we break down every element, explaining not just the “how,” but the “why” behind each ingredient choice.

Ingredients

To achieve the perfect balance of flavors and textures, sourcing high-quality ingredients is essential. The simplicity of a Caesar salad means there is nowhere for poor-quality ingredients to hide.

For the Homemade Garlic Croutons

• Ciabatta or Sourdough Bread (6 ounces): You want an airy, crusty loaf. Remove the toughest parts of the crust and cut into 3/4-inch cubes. The holes in these breads catch the olive oil and garlic better than dense sandwich bread.
• Extra-Virgin Olive Oil (3 tablespoons): Used for toasting the bread.
• Garlic (2 cloves): Minced to a paste or grated on a microplane. This will be tossed with the warm croutons for maximum aroma without burning in the oven.
• Sea Salt and Black Pepper: To taste.

For the Creamy Caesar Dressing

• Extra-Virgin Olive Oil (1/2 cup): Use your best oil here; the flavor will shine through.
• Parmesan Cheese (1/3 cup): Freshly grated is non-negotiable. Pre-grated cheese contains anti-caking agents that ruin the texture.
• Lemon Juice (2 tablespoons): Freshly squeezed. Bottled juice lacks the necessary volatile oils and brightness.
• Garlic (1 clove): Minced or pressed.
• Anchovy Fillets (2 to 3 fillets): Or 1 teaspoon of anchovy paste. This provides the essential umami backbone. Do not skip this; it won’t taste “fishy,” just savory.
• Egg Yolk (1 large): This acts as the emulsifier to make the dressing creamy. (See FAQ for raw egg concerns).
• Dijon Mustard (1 teaspoon): Adds a tangy depth and aids in emulsification.
• Worcestershire Sauce (1/2 teaspoon): Enhances the savory profile.

For the Greens

• Lacinato Kale (2 bunches): Also sold as Tuscan kale or Dinosaur kale. Look for dark blue-green leaves. Avoid yellowing tips.
• Kosher Salt: A pinch is used during the preparation to help break down the kale fibers.
• Shaved Parmesan: For garnish.

Preparation Instructions

Follow these steps meticulously to replicate the texture and flavor balance characteristic of a Test Kitchen-style recipe.

1. Prepare the Kale (The Tenderizing Step):
   

   Wash the kale thoroughly and pat dry. This is crucial; wet kale will water down your dressing. Remove the tough stems by holding the stem end and stripping the leaves downward. Stack the leaves, roll them into tight cigars, and slice them crosswise into thin ribbons (about 1/4-inch wide). Place the kale in a large bowl. Sprinkle with a pinch of salt and drizzle with 1 tablespoon of olive oil. Using your clean hands, massage the kale vigorously for 1 to 2 minutes. You will feel the volume decrease, and the leaves will turn a darker, glossy green. This breaks down the cell walls, making the kale tender.

2. Create the Croutons:
   

   Preheat your oven to 375°F (190°C). In a bowl, toss the bread cubes with 3 tablespoons of olive oil, salt, and pepper. Spread them evenly on a rimmed baking sheet. Bake for 10 to 12 minutes, flipping halfway through, until they are golden brown and crisp. While they bake, mince the 2 cloves of garlic. Immediately upon removing the croutons from the oven, toss them in a bowl with the fresh minced garlic. The residual heat will “cook” the raw edge off the garlic without burning it.

3. Construct the Dressing Base:
   

   On a cutting board, mince the garlic clove and the anchovies together. Sprinkle with a pinch of salt. Using the side of your knife, drag it across the mixture repeatedly to mash it into a smooth paste. Transfer this paste to a medium bowl.

4. Emulsify the Dressing:
   

   To the garlic-anchovy paste, add the egg yolk, lemon juice, Dijon mustard, and Worcestershire sauce. Whisk until well combined. While whisking constantly and vigorously, slowly drizzle in the 1/2 cup of extra-virgin olive oil. Start with a few drops, then a thin stream. The mixture should become thick, pale yellow, and creamy. Stir in the grated Parmesan cheese.

5. Dress and Rest:
   

   Pour the dressing over the massaged kale. Toss thoroughly using tongs or your hands to ensure every ribbon is coated. Unlike Romaine, kale benefits from sitting in the dressing. Let the salad stand for 15 minutes. This allows the acidity in the lemon juice to further tenderize the greens.

6. Final Assembly:
   

   Just before serving, add the garlic croutons and toss again. Transfer to a serving platter. Top with large shavings of Parmesan cheese and a generous crack of black pepper.

Chef’s Pro-Tips for Success

To elevate your salad from “good” to “restaurant-quality,” keep these professional insights in mind:

The Science of Emulsion: The key to a creamy Caesar dressing without mayonnaise is a stable emulsion. The lecithin in the egg yolk and the mucilage in the mustard help suspend the oil droplets within the lemon juice. If you add the oil too fast, the dressing will “break” and look oily rather than creamy. If this happens, start with a fresh bowl containing a teaspoon of warm water and slowly whisk your broken dressing into it.

Temperature Matters: Ensure your egg yolk and lemon juice are at room temperature before you start whisking. Ingredients at similar temperatures emulsify much more easily than cold ingredients straight from the fridge.

Garlic Management: Nothing ruins a salad faster than burnt garlic. This is why we add the garlic to the croutons after they come out of the oven. The heat of the bread releases the garlic oils, perfuming the croutons perfectly without the risk of acrid, burnt bitterness.

Drying the Greens: Use a salad spinner if you have one. If water remains on the kale, the oil-based dressing will slide right off (oil and water don’t mix), resulting in a flavorless bite of greens and a pool of dressing at the bottom of the bowl.

Variations and Substitutions

While the classic recipe is divine, dietary needs and pantry limitations sometimes require flexibility. Here are several tested variations.

The “Mayonnaise Hack” (Egg-Free Dressing)

If you are uncomfortable using raw egg yolks or simply want a faster shortcut, you can substitute the egg yolk and olive oil emulsion with high-quality mayonnaise. Use 1/2 cup of mayonnaise (like Hellmann’s or Duke’s) as the base. Whisk in the garlic, anchovy, lemon, and parmesan. You may need to thin it slightly with a teaspoon of water or extra olive oil to get the right coating consistency.

Grilled Chicken or Salmon Caesar

To turn this side dish into a complete meal, add protein. The robust nature of kale stands up incredibly well to warm proteins. Grilled chicken breast, sliced on the bias, is classic. However, a hot, pan-seared salmon fillet is arguably better; the richness of the salmon fat complements the acidity of the dressing. Add the protein while warm to slightly wilt the kale further.

Gluten-Free Crunch

The croutons are a major source of gluten in this recipe. To make this celiac-friendly, you have two great options. First, simply use gluten-free sourdough bread for the croutons. Alternatively, for a unique twist, replace croutons with crispy roasted chickpeas. Toss drained chickpeas in olive oil and garlic powder and roast at 400°F until crunchy. They add a nutty flavor and excellent texture.

Spicy Kale Caesar

For those who enjoy heat, add red pepper flakes to the oil when tossing the croutons. Additionally, you can add a minced pickled pepper (like a Calabrian chili) to the dressing paste. The heat cuts through the richness of the cheese and egg yolk beautifully.

Frequently Asked Questions

Can I make this salad ahead of time?

Yes, and this is the biggest advantage of kale over Romaine lettuce. Because kale is so fibrous, it actually improves after sitting in the dressing for a while. You can dress the salad up to 4 hours in advance and keep it in the refrigerator. However, do not add the croutons until immediately before serving, or they will become soggy.

Is it safe to consume raw egg yolks?

For most healthy adults, the risk of salmonella from raw eggs is very low, especially if you use pasteurized eggs. Pasteurized eggs have been heat-treated to kill bacteria without cooking the egg. If you are pregnant, elderly, or immunocompromised, use the “Mayonnaise Hack” mentioned in the variations section, or purchase pasteurized liquid egg yolks.

I hate anchovies. Can I skip them?

We strongly advise against skipping them entirely. Anchovies provide glutamates (umami) that make the dressing taste savory, not fishy. If you absolutely cannot use them, substitute with 1 teaspoon of white miso paste or an extra dash of Worcestershire sauce and a teaspoon of capers. These alternatives will provide a similar salty, savory depth.

Can I use curly kale instead of Lacinato?

Yes, but it requires more work. Curly kale is tougher and more fibrous than Lacinato (Dinosaur) kale. If you must use curly kale, you need to spend extra time removing the stems thoroughly and massage the leaves for at least 3 to 4 minutes to ensure they are tender enough to eat raw. You may also want to let the dressed salad sit for 30 minutes instead of 15.

My dressing is too thick. What should I do?

The thickness of the dressing can vary based on the size of the egg yolk and the type of cheese used. If it is too thick to pour, simply whisk in warm water, one teaspoon at a time, until it reaches the consistency of heavy cream. It should coat the back of a spoon but still be fluid.
